Detailed Description

The present invention will be described below with reference to embodiments thereof, but the following embodiments do not limit the invention according to the claims. In addition, a combination of all the features described in the embodiments is not necessarily essential to the means for solving the problems of the present invention. In the drawings, the same or similar portions are denoted by the same reference numerals, and redundant description may be omitted.

Fig. 1 schematically shows a basic configuration of a power supply and reception system 100. The power supply and reception system 100 is a system for performing, for example, V2G (Vehicle-to-Grid) for a power integrator to use a battery provided in a Vehicle to integrate electric power between the Vehicle and a Grid. The power supply and reception system 100 has a function of facilitating connection of a vehicle having a battery with an appropriate remaining capacity for power demand to a grid. Further, a case where at least one of the vehicle discharges electric power to the grid and the vehicle receives electric power from the grid is referred to as V2G.

The power supply and reception system 100 includes a vehicle 30a, a plurality of vehicles including a vehicle 30b and a vehicle 30c, a stationary battery 14, a plurality of charging and discharging devices 20, a management server 40, a power generation device 12, and a plurality of user terminals including a user terminal 82a, a user terminal 82b, and a user terminal 82 c.

User 80a is a user of vehicle 30a, user 80b is a user of vehicle 30b, and user 80c is a user of vehicle 30 c. The user of the vehicle may be an arbitrary person who uses the vehicle, such as the owner of the vehicle or a relative of the owner. In the present embodiment, the users 80a, 80b, and 80c may be collectively referred to as "users 80".

The vehicle 30a includes a battery 32 a. The vehicle 30b includes a battery 32 b. The vehicle 30c includes a battery 32 c. In the present embodiment, a plurality of vehicles including the vehicle 30a, the vehicle 30b, and the vehicle 30c may be collectively referred to as "the vehicle 30". A plurality of batteries including the battery 32a, the battery 32b, and the battery 32c may be collectively referred to as "the battery 32". The battery 32 may be a lithium ion battery, a nickel metal hydride battery, or any other secondary battery.

The battery 32 is an example of a driving power source provided in the vehicle 30. The driving power source includes a power source that consumes fuel such as a fuel cell to generate electric energy to be supplied to a power source of the vehicle 30. The fuel may be hydrogen, gasoline, light oil, hydrocarbon fuel such as natural gas, alcohol fuel, or the like. The driving power source may be any power source capable of generating electric energy to be supplied to the power source of vehicle 30.

The vehicle 30 is an example of a conveyance device. The vehicle 30 is a vehicle having a power source driven by electric energy, such as an electric vehicle or a Fuel Cell Vehicle (FCV). Electric vehicles include hybrid vehicles or plug-in hybrid electric vehicles (PHEVs) that include a battery-operated electric power delivery device (BEV) or an internal combustion engine that provides at least a portion of the power. In the present embodiment, the vehicle 30 is an electric vehicle including a battery 32 as a driving power source. In a system using a battery as a driving power source, discharge of the battery corresponds to discharge of energy from the driving power source, and charge of the battery corresponds to accumulation of energy in the driving power source. The remaining capacity of the battery corresponds to energy stored in the driving power supply, such as electric energy or electric energy that can be supplied from the driving power supply. The free capacity of the battery corresponds to energy that can be further stored in the driving power source, such as electric energy or electric energy that can be further stored in the driving power source.

The user terminal 82a is a communication terminal used by the user 80 a. The user terminal 82b is a communication terminal used by the user 80 b. The user terminal 82c is a communication terminal used by the user 80 c. A plurality of user terminals including the user terminal 82a, the user terminal 82b, and the user terminal 82c are sometimes collectively referred to as "user terminal 82".

The user terminal 82 may be, for example, a portable terminal, a personal computer, a car navigation device, or the like. Examples of the portable terminal include a mobile phone, a smart phone, a PDA, a tablet computer, a notebook computer, a portable computer, and a wearable computer.

The management server 40 is capable of communicating with the vehicle 30, the stationary battery 14, and the user terminal 82 via a communication network. The management server 40 can also communicate with the electric power transaction server 50 through a communication network. The communication network may include transmission paths for wired communication or wireless communication. The communication network may comprise a communication network including the internet, a P2P network, a private line, a VPN, a wire line communication line, a handset line, etc.

The power grid 10 may comprise a power supply system or a power distribution system of a power system, a distribution grid of a power grid. The grid 10 may be geographically located. The grid 10 may be a small scale grid. The power grid 10 may be any size of power distribution network that connects power devices that consume power to a power source. For example, the power grid 10 may be a power distribution grid installed at any facility such as the commercial facility 150. The power grid 10 may be provided by a building. The vehicle 30, the stationary battery 14, the charge and discharge device 20, and the power generation device 12 are connected to the grid 10. The charge/discharge device 20, the stationary battery 14, and the power generation device 12 can supply and receive electric power to and from the grid 10. Further, charge/discharge device 20 is an example of a power supply/reception device for supplying and receiving electric power between vehicle 30 and grid 10. The charge/discharge device 20 and the stationary battery 14 are examples of electrical devices for accumulating energy in a driving power source provided in the vehicle 30.

The power generation facility 12 is managed by a power company or the like. The charging/discharging facility 20 includes, for example, a charger and discharger installed in a house, a charging/discharging station installed in a parking lot or a public space of an apartment, a building, or a commercial facility 150, and the like.

The vehicle 30 is connected to the charge and discharge device 20 through the charge and discharge cable 22. That is, the vehicle 30 is connected to the grid 10 via the charging/discharging cable 22 and the charging/discharging device 20. The vehicle 30 receives power between the battery 32 and the power grid 10 through the charge and discharge device 20. For example, the vehicle 30 discharges the power essential oil charge and discharge cable 22 and the charge and discharge device 20 obtained by discharging the battery 32 to the power grid 10. Further, the vehicle 30 charges the battery 32 with electric power supplied from the grid 10 via the charge/discharge cable 22 and the charge/discharge device 20. In addition, the power supply and reception with the grid 10 may be referred to as "power supply and reception with the grid 10" or the like.

The stationary battery 14 is managed by a power integrator. The battery 32 of the vehicle 30 forms a virtual power generation station together with the stationary battery 14. The management server 40 is managed by the power integrator. The management server 40 controls power supply and reception between the battery 32 and the power grid 10, and between the stationary battery 14 and the power grid 10.

The management server 40 conducts power trading by bidding in the power wholesale market. The electricity trading server 50 is managed by an operator of the electricity wholesale market. The management server 40 bids on the electricity trading server 50 for a time unit of 1 section of 30 minutes. The management server 40 discharges the battery 32 and the stationary battery 14 in each section based on the contract result, and supplies electric power to the grid 10.

For example, the management server 40 discharges the battery 32 and the stationary battery 14 in accordance with an amount of contract for bidding by a power integrator in the power wholesale market, and supplies the power discharged from the battery 32 and the stationary battery 14 to the grid 10. The management server 40 controls charging and discharging of the battery 32 and the stationary battery 14 within a range of adjustment force for bidding engagement by the power integrator in the supply and demand adjustment market, thereby adjusting the power supply and demand on the power grid 10. For example, the management server 40 controls charging and discharging of the battery 32 and the stationary battery 14 according to an increase demand response (increase DR), a decrease demand response (decrease DR), and an increase/decrease demand response (increase/decrease DR) from a distribution company or a retail electric power company.

Specifically, the management server 40 controls at least one of the vehicle 30 and the charge/discharge device 20 in accordance with the increase DR, thereby charging the battery 32 of the vehicle 30 with the electric power received from the grid 10 by the charge/discharge device 20. In addition, the management server 40 controls at least one of the vehicle 30 and the charging/discharging device 20 according to the drop DR, thereby discharging the battery 32 of the vehicle 30 and discharging the electric power obtained by the discharge of the battery 32 to the grid 10 through the charging/discharging device 20.

In the present embodiment, management server 40 prompts user 80 of vehicle 30, whose remaining capacity and free capacity of battery 32 are respectively greater than a preset capacity value, to connect to grid 10. The vehicle 30 having a large remaining capacity and a large vacant capacity of the battery 32 can supply power to the grid 10 when the power supplied from the power generation facility 12 is insufficient for the power demand, and can absorb the remaining power when the power supplied from the power generation facility 12 is excessive for the power demand, for example. Therefore, it is possible to cope with both a case where the power demand is large and a case where the power demand is small in the grid 10 by using fewer vehicles 30. Therefore, the power integrator can ensure the capacity capable of supplying power between the vehicle 30 and the grid 10 by managing a small number of vehicles 30.

In the present embodiment, power supply and reception means that transmission and reception of electric power from at least one of vehicle 30 and grid 10 to the other occurs. For example, supplying power may mean performing discharge of electric power from vehicle 30 to grid 10. In addition, supplying power may mean performing power supply from the grid 10 to the vehicle 30. In addition, when vehicle 30 discharges electric power through a charger/discharger provided at an electric power consumption place such as a house, if the electric power consumption on the electric power consumption place side is larger than the electric power discharged by vehicle 30, a net power supply to grid 10 does not occur at a connection point between the electric power consumption place side and grid 10, and the amount of electric power supplied from the connection point to the electric power consumption place may simply decrease. Even in such a case, when viewed from the grid 10, it can be considered that electric power reception and supply have occurred with respect to the outside of the grid 10. Therefore, in the present embodiment, in the case of power supply and reception with grid 10 when vehicle 30 is discharging electric power, it is irrelevant whether or not grid 10 receives net electric power from a specific connection point with vehicle 30.

Fig. 2 schematically shows a functional configuration of the management server 40. The management server 40 includes a processing unit 42, a storage unit 48, and a communication unit 46.

The processing unit 42 is realized by a processing device including a processor. The storage unit 48 is implemented by a nonvolatile memory device. The processing unit 42 performs processing using the information stored in the storage unit 48. The communication section 46 is responsible for communication between the vehicle 30, the stationary battery 14, the user terminal 82, and the electric power transaction server 50. The information received by the communication unit 46 from the vehicle 30, the stationary battery 14, the user terminal 82, and the electric power transaction server 50 is supplied to the processing unit 42. Information transmitted to the vehicle 30, the stationary battery 14, the user terminal 82, and the electric power transaction server 50 is generated by the processing unit 42 and transmitted via the communication unit 46.

The management server 40 functions as a power supply and reception management device. The management server 40 may be a system realized by 1 information processing apparatus, or may be a system realized by a plurality of information processing apparatuses.

Processing unit 42 includes selection unit 200, notification control unit 230, capacity information acquisition unit 240, capacity presentation control unit 250, reward control unit 270, power supply and reception control unit 280, and demand information acquisition unit 290.

The storage unit 48 includes a reward information storage unit 282 and a history storage unit 284. The reward information storage unit 282 stores reward information indicating a reward (reward) provided to the user 80. The history storage unit 284 stores history information including the travel history of the vehicle 30.

The demand information acquisition unit 290 acquires information indicating the demand for electric power in the power grid 10. In response to the power demand, selection unit 200 selects vehicle 30 having battery 32 with a remaining capacity greater than a predetermined remaining capacity value and a free capacity greater than a predetermined free capacity value as vehicle 30 to receive and supply power to and from grid 10. As will be described later, selection unit 200 may select vehicle 30 including battery 32 having a remaining capacity greater than a predetermined remaining capacity value Δ 1 and a free capacity greater than a predetermined free capacity value Δ 2 as vehicle 30 that supplies and receives power to and from grid 10.

The notification control unit 230 notifies the user 80 of the vehicle 30 selected by the selection unit 200. For example, the notification control unit 230 transmits notification information for the user 80 via the communication unit 46 to cause the user terminal 82 to perform notification for the user 80.

The information representing the demand for electric power may be information representing the demand for adjustment force in the power grid 10. When the demand for the adjustment force is larger than the preset value, the selection unit 200 may select the vehicle 30 having the battery 32 with the remaining capacity larger than the preset remaining capacity value and the vacant capacity larger than the preset vacant capacity value as the vehicle 30 that receives and supplies power from the grid 10, in preference to the other vehicles 30.

Notification control unit 230 may notify user 80 of vehicle 30 selected by selection unit 200 of a reward for a case where vehicle 30 can supply and receive power with grid 10. Further, when power can be supplied to and received from grid 10 by vehicle 30 selected by selection unit 200, reward control unit 270 associates reward information indicating a reward for the case where power can be supplied to and received from grid 10 by vehicle 30 with user 80 of vehicle 30. For example, reward control unit 270 may store reward information associated with user 80 in reward information storage unit 282. In the present embodiment, connection of vehicle 30 to charge/discharge device 20 is an example of "vehicle 30 can supply and receive power to and from grid 10".

The selection unit 200 selects a vehicle 30 having a battery 32 that stores more energy than a preset amount of energy and can store more energy than a preset amount of energy as a vehicle 30 that supplies and receives power to and from the grid 10, according to the power demand. For example, selection unit 200 may select, as vehicle 30 that receives power from grid 10, vehicle 30 that includes battery 32 having a remaining capacity greater than a predetermined remaining capacity value, a free capacity greater than a predetermined free capacity value, and a temperature of battery 32 within a predetermined range, in accordance with a power demand.

In response to the power demand, selection unit 200 may select, as vehicle 30 that receives power from grid 10, vehicle 30 that includes battery 32 having a remaining capacity greater than a predetermined remaining capacity value, a free capacity greater than a predetermined free capacity value, and a temperature of battery 32 within a predetermined range determined based on the remaining capacity of battery 32.

Power supply and reception control unit 280 supplies and receives power to and from grid 10 in accordance with the power demand, and allows vehicle 30 to supply and receive power to and from grid 10. For example, power supply and reception control unit 280 communicates with the ECU of vehicle 30, and sequentially acquires power supply and reception permission information indicating whether or not vehicle 30 is connected to charge/discharge device 20 capable of supplying and receiving power to and from power grid 10. When vehicle 30 can receive power from power grid 10, power supply/reception control unit 280 instructs the ECU included in vehicle 30 to charge/discharge battery 32 in accordance with the power demand acquired by demand information acquisition unit 290. The ECU of vehicle 30 communicates with charge/discharge device 20 in accordance with an instruction from power supply/reception control unit 280, and controls the power converter of vehicle 30 to charge battery 32 via charge/discharge device 20 or discharge electric power obtained by discharging battery 32. Further, power supply and reception control unit 280 may sequentially acquire, from the ECU of vehicle 30, information indicating the amount of input power from charge/discharge device 20 to the power converter when battery 32 is charged, the amount of output power from the power converter to charge/discharge device 20 when battery 32 is discharged, and the soc (state of charge) of battery 32. Power supply and reception control portion 280 may control power supply and reception between vehicle 30 and grid 10 based on information acquired from the ECU of vehicle 30.

The amount of contract in the above-described power transaction is an example of information indicating the power demand. The information indicating the power demand may be a contract price in the power trade, a contract category indicating whether to buy or sell a contract. The information indicating the power demand may be information indicating the real-time supply and demand unbalance amount in the grid 10 or information indicating a predicted value of the future supply and demand unbalance amount. The information indicating the power demand may be information indicating the real-time power consumption amount at the electricity consumption site of the power grid 10 or a predicted value of the power consumption amount. As the information indicating the power demand, various information that directly or indirectly affects the power demand, such as temperature information, humidity information, weather information, and activity information, can be used without being limited to the amount of electricity itself. Further, as the electricity trading market, trading markets such as a one-day market, and a demand market may be mentioned. As a transaction method of the electric power transaction, various transaction methods other than those in the electric power transaction market can be used.

The capacity information acquisition unit 240 acquires information indicating a minimum capacity value to be secured for the battery 32 provided in the vehicle 30 from the user 80 of the vehicle 30. For example, the capacity information acquisition unit 240 acquires information indicating the minimum capacity value input to the user terminal 82 via the user terminal 82 and the communication unit 46.

The power supply and reception control unit 280 may supply and receive power with the grid 10 so that the remaining capacity of the battery 32 is not less than the minimum capacity value. Selection unit 200 may select, as vehicle 30 that receives power from power grid 10, vehicle 30 that includes battery 32 having a remaining capacity greater than the sum of a predetermined remaining capacity value and a minimum capacity value of battery 32 and having a free capacity greater than a predetermined free capacity value. For example, as described later, selection unit 200 may select, as vehicle 30 that receives power from grid 10, vehicle 30 that includes battery 32 having a remaining capacity greater than the sum of predetermined remaining capacity value Δ 1 and minimum capacity value Cmin and a remaining capacity greater than predetermined remaining capacity value Δ 2.

The capacity presentation control unit 250 presents information indicating the recommended value of the minimum capacity value to the user 80 based on the travel history of the vehicle 30. For example, the capacity presentation control unit 250 calculates a recommended value of the minimum capacity value based on the travel history information stored in the history storage unit 284. The capacity presentation control unit 250 transmits information indicating the calculated recommended value of the minimum capacity value to the user terminal 82 via the communication unit 46, and causes the user terminal 82 to present the recommended value of the minimum capacity value to the user 80. Further, the smaller the minimum capacity value acquired from the user 80, the reward control unit 270 associates information indicating a greater reward with the user 80.

Management server 40 facilitates connection of a vehicle, which holds a remaining battery capacity and a free capacity that can correspond to a change in power demand, to power grid 10. Therefore, the power integrator can reduce the number of vehicles 30 that need to be managed to ensure the power supply and reception capacity with the grid 10. Further, stabilization of the grid 10 is facilitated.

The function of the power supply and reception management apparatus may be realized by the management server 40 alone, or may be realized by a combination of the management server 40 and the ECU of the vehicle 30. For example, at least a part of the processing performed by the management server 40 may be performed by the ECU of the vehicle 30. For example, at least a part of the functions realized by selection unit 200, notification control unit 230, capacity information acquisition unit 240, capacity presentation control unit 250, reward control unit 270, power supply and reception control unit 280, demand information acquisition unit 290, reward information storage unit 282, and history storage unit 284 may be realized by an ECU of vehicle 30.

FIG. 3 is a diagram for explaining the remaining capacity of the battery 32And a schematic of the free capacity. In FIG. 3, C_totalIndicating the overall capacity of the battery 32. E.g. C_totalMay be the full charge capacity of the battery 32.

C1 represents the minimum capacity that should be ensured in battery 32. The ECU of vehicle 30 controls the discharge of battery 32 so that the SOC of battery 32 does not become lower than the SOC corresponding to C1. C2 represents the charge-prohibited capacity in the battery 32. The ECU of the vehicle 30 prevents, for example, the overcharge of the battery 32 so that the SOC of the battery 32 does not exceed C_total-SOC corresponding to C2, controlling the charging of the battery 32. For example, at C1 and C2 are each C_totalThe ECU of the vehicle 30 controls the charge and discharge of the battery 32 in such a manner that the SOC of the battery 32 is in the range of 5% to 95%.

Cmin represents a minimum capacity value specified by the user 80 that should be secured for the battery 32. When power supply/reception control unit 280 of management server 40 discharges battery 32, the discharge is performed so that the SOC of battery 32 is not less than the SOC corresponding to C1+ Cmin. When power supply/reception control unit 280 supplies and receives power to and from grid 10, SOC of battery 32 is controlled to be equal to or higher than C1+ Cmin to C_totalThe charge and discharge of the battery 32 are controlled so as to fall within the SOC range corresponding to-C2. Thereby, the user 80 can use the battery capacity corresponding to at least Cmin in the vehicle 30.

C3 represents the current residual capacity of the battery 32. Cr represents a remaining capacity available in the battery 32. Specifically, the residual capacity Cr is C3-C1. The remaining capacity Cr does not include C1. That is, Cr is a dischargeable capacity allowed in the battery 32. Cf represents a free capacity available in the battery 32. Specifically, the free capacity Cf is C_total-C2. The capacity Cf does not include C2. That is, Cf is a chargeable capacity allowed in the battery 32.

In fig. 3, Δ 1 represents a remaining capacity value desired for demand and supply adjustment. Δ 2 represents the amount of headroom desired for demand adjustment. The selection unit 200 of the management server 40 selects a vehicle 30 whose remaining capacity Cr exceeds at least the remaining capacity value Δ 1 and whose free capacity exceeds at least the free capacity value Δ 2 as a vehicle 30 to be supplied and received with the grid 10.Δ 1 and Δ 2 may be the same value or different values.

As shown in fig. 3, when Cmin is specified by user 80, selection unit 200 selects vehicle 30 whose remaining capacity Cr exceeds at least Cmin + Δ 1 and whose free capacity exceeds at least Δ 2 as vehicle 30 to be supplied and received with power grid 10. The vehicle 30 in which the remaining capacity Cr exceeds Cmin + Δ 1 and the free capacity Cf exceeds Δ 2 is selected. Reward control unit 270 calculates a reward to user 80 when selected vehicle 30 is connected to charge/discharge device 20, based on at least remaining capacity Cr and free capacity Cf.

For example, when the vehicle 30 is connected to the charge/discharge device 20, a basic reward is given regardless of Cr and Cf of the battery 32. The user 80 of the vehicle 30 having the battery 32 with the remaining capacity Cr exceeding Cmin + Δ 1 and the free capacity Cf exceeding Δ 2 is rewarded (returned) in addition to the basic reward.

For the reward payment, for example, the coefficient K0 and the coefficient K are multiplied by the capacity value of the smaller one of Cr — Cmin and Cf_TTo calculate. The coefficient K0 is a conversion coefficient for converting into points as a reward given to the user 80. Coefficient K_TIs a coefficient of 0 or more determined by the temperature of the battery 32. For coefficient K_TAs will be described later.

The consideration controller 270 associates the information indicating the bonus consideration with the user 80 of the vehicle 30 selected by the selector 200. The reward control unit 270 transmits information indicating the reward of the bonus to the user terminal 82 via the communication unit 46, and presents the information from the user terminal 82 to the user 80.

Fig. 4 is a diagram schematically showing a case where the free capacity Cf of the battery 32 is smaller than the free capacity value Δ 2 for demand adjustment. In the case where the free capacity Cf is smaller than the free capacity value Δ 2, the prize payout is 0. That is, when the vehicle 30 having the battery 32 with the free capacity Cf smaller than the free capacity value Δ 2 is connected to the charge/discharge device 20, the reward control unit 270 gives only the basic reward to the user 80, and does not give the reward.

Fig. 5 is a graph showing the dependence of the amount of heat generated in the battery 32 on the SOC during charging and discharging of the battery 32. The vertical axis of fig. 5 represents the amount of heat generated. The region where the heat is larger than 0 indicates that heat release occurs, and the region where the heat is smaller than 0 indicates that heat absorption occurs. The horizontal axis of fig. 5 represents SOC.

When the SOC is larger than S2 or smaller than S1, an endothermic reaction occurs and when the SOC is larger than S1 and smaller than S2, an exothermic reaction occurs during charging of the battery 32. The maximum value of the amount of heat release is obtained at SOC S3.

On the other hand, when the SOC is larger than S2 or smaller than S1, an exothermic reaction occurs, and when the SOC is larger than S1 and smaller than S2, an endothermic reaction occurs during discharge of the battery 32. The endothermic quantity maximum value is obtained at SOC S3.

For the battery 32, a temperature range that allows the battery 32 to be charged or discharged is generally set. When the temperature of the battery 32 is outside this temperature range, the ECU of the vehicle 30 does not charge and discharge the battery 32.

Therefore, for example, when the battery 32 is charged in a case where the SOC of the battery 32 is between S1 and S2 and the temperature of the battery 32 is in the vicinity of the upper limit of the temperature range, the temperature of the battery 32 exceeds the upper limit of the temperature range due to heat generation accompanying the charging, and the charging of the battery 32 may be stopped. For example, when the battery 32 is discharged when the SOC of the battery 32 is between S1 and S2 and the temperature of the battery 32 is near the lower limit of the temperature range, if the temperature of the battery 32 is lower than the lower limit of the temperature range due to heat absorption accompanying the discharge, the discharge of the battery 32 may be stopped.

Therefore, depending on the SOC of battery 32 and the temperature of battery 32, there is a possibility that power supply and reception between battery 32 and grid 10 cannot be performed. Therefore, it is preferable that selection unit 200 further selects vehicle 30 to be supplied with and received from grid 10, taking into account the SOC of battery 32 and the temperature of battery 32.

Fig. 6 is a graph showing conditions for determining the chargeable and dischargeable battery 32. The vertical axis of fig. 6 represents the battery temperature, and the horizontal axis represents the SOC of the battery.

Region 600 represents the conditions satisfied by chargeable and dischargeable battery 32. Selection unit 200 identifies battery 32 having a battery temperature and an SOC within region 600 as chargeable and dischargeable battery 32.

Region 600 is the region between line 601 and line 602. The line 601 has a maximum value at S1 and S2 and a minimum value at S3. The line 602 has a minimum value at S1 and S2 and a maximum value at S3. The temperature shown on any SOC line 601 is higher than the temperature shown on line 602. The line 601 and the line 602 are predetermined in consideration of heat release and heat absorption accompanying charge and discharge described in association with fig. 5 so that the temperature of the battery 32 is within a chargeable and dischargeable temperature range regardless of which of the charge and discharge of the battery 32 is performed.

Selection unit 200 preferentially selects vehicle 30 including battery 32 having a battery temperature and an SOC within region 600 over vehicle 30 having a battery temperature and an SOC not within region 600. For example, selection unit 200 selects vehicle 30 having battery 32 with the battery temperature and SOC within region 600 as vehicle 30 to be supplied with power from grid 10, and does not select vehicle 30 having battery 32 with the battery temperature and SOC outside region 600 as vehicle 30 to be supplied with power from grid 10.

Specifically, selection unit 200 preferentially selects vehicle 30 including battery 32 whose current battery temperature is lower than the temperature determined by current SOC and line 601 and whose current battery temperature is higher than the temperature determined by current SOC and line 602, as the vehicle to be supplied and received with power grid 10.

In addition, the coefficient K is in the region 600_TIs set to be larger than 0, and has a coefficient K in a region outside the region 600_TIs set to 0. As described in connection with FIG. 3, reward control unit 270 will be based on K0, Cr and Cf, and coefficient K_TThe determined bonus payment is given to the user 80 of the vehicle 30 selected by the selection part 200.

This makes it possible to give a reward to the user 80 of the vehicle 30 having the battery 32 whose battery temperature is in the chargeable and dischargeable temperature range. Therefore, for example, it is possible to preferentially select the vehicle 30 that has the SOC capable of providing the adjustment force of the power supply and demand and that can be reliably charged and discharged, and to provide a reward to the user of the vehicle 30.

The temperature change during charging and discharging of the battery 32 is also determined by the ambient temperature. Therefore, the condition shown by the area 600 shown in fig. 6 may be set in plural in correspondence with plural ambient temperatures. Based on the temperature and SOC of battery 32, selection unit 200 may select vehicle 30 that satisfies a condition corresponding to the current ambient temperature around vehicle 30 as the vehicle to be supplied and received with power grid 10.

The thermal characteristics of the battery shown in fig. 5 are determined by the type of battery pack constituting the battery 32. Therefore, the condition shown in fig. 6 can be set for each kind of battery 32.

Fig. 7 shows an example of the history information stored in the history storage unit 284 in a table format. The history information associates the vehicle ID, time of day, battery SOC, battery temperature, vehicle position, and vehicle state.

The vehicle ID stores therein identification information of the vehicle 30. The time or the period of acquiring the history is stored. The SOC of the battery 32 is stored in the battery SOC. The battery temperature retains the temperature of the battery 32. The vehicle position stores the position of the vehicle 30. As the position information, in addition to geographical information such as latitude and longitude information, any information that can specify the position of vehicle 30, such as identification information of charge/discharge device 20 connected to vehicle 30, information indicating whether it is a house, or the like, can be used. The vehicle state stores the state of the vehicle 30. The state of the vehicle 30 may be stopped, started, running, started, charged, or charged. The management server 40 may sequentially receive vehicle data acquired by the ECU of the vehicle 30 from the ECU of the vehicle 30, and generate history information based on the received vehicle data.

Further, the capacity presentation control unit 250 may determine a recommended value of the minimum capacity value Cmin for each vehicle 30 based on the history information. For example, the capacity presentation control unit 250 may specify a travel pattern repeated in the vehicle 30 with reference to the history information, and determine the minimum capacity value Cmin based on the amount of electricity consumed when traveling in the specified travel pattern. The capacity presentation control unit 250 may transmit information indicating the determined minimum capacity value Cmin to the user terminal 82 through the communication unit 46.

Fig. 8 is a flowchart related to a process of selecting a vehicle 30 to be supplied with power from grid 10. The flowchart of fig. 8 is executed mainly by the processing unit 42 of the management server 40. The processing of the present flowchart may be executed periodically in the management server 40, for example. For example, the processing of the present flowchart may be performed every 30 minutes. For example, the processing of the flowchart may be executed at a time point N hours before the start time of each section for each section of 30 minutes which is a bidding unit of the power trading.

In S802, the demand information acquiring unit 290 acquires the adjustment force contract result information. For example, the demand information acquiring unit 290 acquires the contract result information of the adjustment force in the section of 30 minutes after the current start of N hours.

In S804, the selection unit 200 determines whether the amount of the adjustment force exceeding a predetermined threshold. The approximate quantitative amount of the adjustment force is an example of information indicating the magnitude of the adjustment force provided by the vehicle 30. When the amount of the adjustment force exceeds the predetermined threshold, in S806, selection unit 200 selects vehicle 30 to be supplied and received with power grid 10. For example, as described in association with fig. 3 to 6, the selection unit 200 selects the vehicle 30 based on the SOC and the temperature of the battery 32, the remaining capacity value Δ 1 for supply and demand adjustment, the empty capacity value Δ 2 for supply and demand adjustment, the minimum capacity value Cmin, and the like.

In S808, a bonus reward for the connection with the charge and discharge device 20 is calculated for each of the vehicles 30 selected in S806. For example, as described in connection with fig. 3 to 6, reward control unit 270 is based on K0 and K_TThe remaining capacity Cr, the remaining capacity value Delta 1 and the free capacity Cf determine a prize payout.

In S810, the consideration controller 270 transmits the bonus consideration information indicating the bonus consideration determined in S808 to the user terminal 82, thereby notifying the user 80 of the bonus consideration and ending the processing of the flowchart. When it is determined in S804 that the amount of the adjustment force is equal to or less than the predetermined threshold, the process of the flowchart is terminated.

Fig. 9 shows an example of a bonus prize payment notification screen 900. The notification screen 900 is displayed to the user terminal 82 in response to the user terminal 82 receiving bonus award information from the management server 40. The notification screen 900 includes a notification item 910. The notification item 910 includes information 912 indicating a period during which the bonus payment is given, and information 914 indicating a range of battery remaining amounts during which the bonus payment is given.

Since the notification screen 900 can notify the user 80 of the period in which the bonus payment is given in advance, the user 80 can be prompted to connect the vehicle 30 and the charge and discharge device 20. In addition, since the range of the remaining amount of the battery for which the reward is given can be notified to the user 80, the user 80 can be prompted to connect the vehicle 30 and the charge and discharge device 20 in a state in which the remaining amount of the battery 32 is within the range.

Fig. 10 is a flowchart related to a process of notifying a reward for a case where the vehicle 30 is connected to the charge and discharge device 20. The flowchart of fig. 10 is mainly executed by the processing unit 42 of the management server 40. The processing of the flowchart may be periodically executed in the management server 40, for example. For example, the processing of the present flowchart is performed for each day of each vehicle 30.

In S1002, reward control unit 270 determines a period during which vehicle 30 is connected to charge/discharge device 20. Reward control unit 270 specifies the period during which vehicle 30 is connected to charge/discharge device 20, based on the history information shown in fig. 7 and the like. In S1004, reward control unit 270 calculates a basic reward from the time when vehicle 30 is connected to charge/discharge device 20. Reward control unit 270 calculates a basic reward from the time period during which vehicle 30 is connected to charge/discharge device 20.

In S1006, reward control unit 270 determines whether or not there is a period in which the state of battery 32 satisfies the condition for giving a reward during the period in which vehicle 30 is connected to charge/discharge device 20. For example, reward control unit 270 determines whether or not there is a period in which the SOC and the temperature of battery 32 at the start time of each period are present in region 600 shown in fig. 6 during the period of connection to charge/discharge device 20.

If it is determined in S1006 that the state of the battery 32 satisfies the condition for giving a bonus payment, it is determined in S1In 008, reward control unit 270 determines a bonus reward to be given to user 80. For example, as described in connection with fig. 3 to 6, etc., reward control unit 270 is based on K0 and K_TThe remaining capacity Cr, the remaining capacity value Δ 1, and the free capacity Cf determine a prize payout.

In S1010, the reward controller 270 stores reward information indicating the sum of the basic reward and the bonus reward determined in S1008 in the reward information storage 282 in association with the identification information of the user 80. In S1012, the reward control unit 270 notifies the user 80 of the bonus reward by transmitting bonus reward applying information indicating the bonus reward to the user terminal 82, and ends the processing of the flowchart.

When it is determined in S1006 that the state of the battery 32 does not satisfy the condition for giving a bonus reward, in S1020, the reward controller 270 stores reward information indicating the basic reward in the reward information storage 282 in association with the identification information of the user 80, and ends the processing of this flowchart.

Fig. 11 shows an example of a notification screen 1100 of a bonus payment given to the user 80. The notification screen 1100 is displayed to the user terminal 82 in response to the user terminal 82 receiving bonus award information from the management server 40. The notification screen 1100 includes a notification item 1110. The notification item 1110 includes information 1112 indicating the bonus payment given to the user 80, and information 1114 indicating the SOC range in which the bonus payment is given.

By the notification screen 1100, the user 80 can be notified that the bonus payment has been given, and thus it can be promoted that the user 80 constantly connects the vehicle 30 and the charge and discharge device 20. In addition, since the range of the remaining amount of the battery for which the reward is given can be notified to the user 80, the user 80 can be prompted to connect the vehicle 30 and the charge and discharge device 20 in a state in which the remaining amount of the battery 32 is within the range.

Fig. 12 shows an example of the reward information stored in the reward information storage unit 282 in a table format. And the reward information establishes correspondence between the user ID, the current points and the accumulated points.

The user ID stores identification information of the user 80. The current points hold the current points being offered to the user 80. The accumulated points are stored as a total value of points provided to the user 80 up to the present time. The accumulated points store a total value of points provided to the user 80 from a time point before a preset time to the present time.

The accumulated point can be used as an expected value for the user 80 to connect the vehicle 30 and the charge/discharge device 20 for a predetermined period. Reward control unit 270 may give preference to a reward such as a coupon in commercial facility 150 to user 80 with a higher accumulated point. The current points provided to user 80 may be available as a price for the goods of commercial facility 150. Further, reward control unit 270 may set a price for buying electricity from battery 32 of vehicle 30 and a price for selling electricity to vehicle 30, based on the accumulated points. For example, reward control unit 270 may set the electricity purchase price higher and the electricity sale price lower as the number of accumulated points increases.

In the power supply and reception system 100, the user 80 can use the point provided to the user 80 for charging the vehicle 30 with the stationary battery 14 in an emergency or disaster. For example, when the current point of the user 80 is equal to or more than a predetermined value and the remaining capacity of the battery 32 of the vehicle 30 of the user 80 is lower than the predetermined value, the processing unit 42 of the management server 40 subtracts the predetermined number of points from the current point provided to the user 80, and in exchange for this, allows the charging of the battery 32 by the stationary battery 14.

In the present embodiment, a description has been given of a mode in which points as an example of a reward are given to the user 80. The reward is not limited to points. For example, a discount of the utilization cost of the charge and discharge device 20, a discount of the utilization cost of the parking lot of the commercial setting 150, a discount of purchase tickets of commodities in the commercial facility 150, and the like can be used as consideration. Any thing can be used as a reward as long as the user 80 is given valuable things or incentive measures, and not limited to money or non-money.

According to the power supply and reception system 100 described above, connection of the vehicle 30 having the rechargeable battery 32 to the grid 10 can be promoted in response to a change in power demand. Therefore, the power integrator can reduce the number of vehicles 30 to be managed to secure the power supply and reception capacity with the grid 10. Thus, the power integrator easily ensures the supply and reception capacity, and thus contributes to stabilization of the grid 10.

FIG. 13 illustrates an example of a computer 2000 capable of embodying, in whole or in part, various embodiments of the invention. The program installed in the computer 2000 can cause the computer 2000 to function as an apparatus such as the management server 40 according to the embodiment or each unit of the apparatus, execute an operation associated with the apparatus or each unit of the apparatus, and/or execute a process according to the embodiment or a step of the process. Such programs may be executed by CPU2012 in order to cause computer 2000 to perform the process flows described herein and the specific operations associated with some or all of the functional blocks of the block diagrams.

The computer 2000 further includes a ROM2026, a flash memory 2024, a communication interface 2022, and an input/output chip 2040. The ROM2026, the flash memory 2024, the communication interface 2022, and the input/output chip 2040 are connected to the main controller 2010 via the input/output controller 2020.

The CPU2012 operates in accordance with programs stored in the ROM2026 and the RAM2014, thereby controlling the respective units.

The communication interface 2022 communicates with other electronic devices via a network. The flash memory 2024 stores programs and data used by the CPU2012 in the computer 2000. The ROM2026 stores a startup program and the like executed by the computer 2000 when activated and/or a program dependent on the hardware of the computer 2000. The input/output chip 2040 may also connect various input/output units such as a keyboard, a mouse, and a monitor to the input/output controller 2020 via input/output ports such as a serial port, a parallel port, a keyboard port, a mouse port, a monitor port, a USB port, and an HDMI (registered trademark) port.

The program is provided via a computer-readable medium such as a CD-ROM, DVD-ROM, or usb-disk, or a network. RAM2014, ROM2026, or flash memory 2024 are examples of computer-readable media. The program is installed to the flash memory 2024, the RAM2014, or the ROM2026, and executed by the CPU 2012. The information processing described in these programs is read by the computer 2000, and the cooperation between the programs and the various types of hardware resources described above is realized. The apparatus or method may be constituted by performing operations or processes on information in compliance with the use of the computer 2000.

For example, in the case of performing communication between the computer 2000 and an external device, the CPU2012 may execute a communication program loaded into the RAM2014, and instruct communication processing to the communication interface 2022 based on processing described in the communication program. The communication interface 2022 reads transmission data stored in a transmission buffer processing area provided in a recording medium such as the RAM2014 and the flash memory 2024 under the control of the CPU2012, transmits the read transmission data to a network, and writes reception data received from the network into a reception buffer processing area provided in the recording medium or the like.

In addition, the CPU2012 can retrieve information in files, databases, etc., within the recording medium. For example, when a plurality of items each having an attribute value of the 1 st attribute associated with an attribute value of the 2 nd attribute are stored in the recording medium, the CPU2012 may retrieve an item that matches the condition, which specifies an attribute value of the 1 st attribute, from among the plurality of items, and read the attribute value of the 2 nd attribute stored in the item, thereby acquiring the attribute value of the 2 nd attribute associated with the 1 st attribute satisfying the preset condition.

The programs or software modules described above may be stored on a computer readable medium on or near the computer 2000. A recording medium such as a hard disk or a RAM provided in a server system connected to a dedicated communication network or the internet can be used as the computer-readable medium. The program stored in the computer-readable medium can be provided to the computer 2000 via a network.
