Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

Fig. 1 is an application scenario of a vehicle charging duration calculation method according to an exemplary embodiment of the present disclosure, as shown in fig. 1, the scenario includes a vehicle end 2 and a cloud platform end 1, and the cloud platform end 1 and the vehicle end 2 may be connected through a preset network connection protocol for communication. The cloud platform end 1 and the vehicle end 2 can jointly execute the method for calculating the vehicle charging time. The vehicle end 2 continuously uploads operating data generated in the vehicle to the cloud platform end 1 in an awake state, and the operating data may be sent to the cloud platform end 1 in a form of a CAN (Controller Area Network) message. The cloud platform end 1 may be provided with a corresponding data parsing module (not shown) and a corresponding data conversion module (not shown) to parse the operating data into a data format that CAN be processed by the cloud platform end 1, and convert data to be sent to the vehicle end 2 in the cloud platform end 1 into a data format of the CAN packet. In addition, a data cleaning module (not shown) may be further disposed in the cloud platform end 1 to clean and filter the vehicle operation data sent by the vehicle end, and remove invalid data, so as to save a storage space of the cloud platform end 1.

In one possible implementation, the vehicle charging period calculation method shown according to yet another exemplary embodiment of the present disclosure may also be applied only in the vehicle end 2.

Fig. 2 is a flowchart illustrating a vehicle charging period calculation method according to an exemplary embodiment of the present disclosure. As shown in fig. 2, the method includes steps 201 to 203.

In step 201, the current remaining battery capacity is obtained. The current BATTERY remaining amount may be acquired by, for example, a BATTERY management system (BATTERY MANAGEMENT SYSTEM, BMS) in the vehicle terminal 2.

In step 202, historical charging data corresponding to the vehicle is obtained, wherein the historical charging data comprises historical charging time corresponding to each battery power interval. The historical charging data may include charging data generated during one or more charging processes that have been completed. The battery power interval may be an interval divided by the percentage of the battery power in the total battery capacity, for example, a battery power interval is defined between 0% and 1% of the battery power, and the historical charging time corresponding to the battery power interval is the time consumed for charging from the state of 0% of the battery power to the state of 1% of the battery power in any one charging process in the historical charging data.

When the historical charging data includes charging data generated in a plurality of charging processes, only one or a plurality of actual effective historical charging times corresponding to each battery power interval may be available, or the possibility that a certain battery power interval does not have corresponding actual effective historical charging time in the historical charging data may also occur. For example, when the plurality of charging processes included in the historical charging data are all charging processes performed by starting with the battery level 10% as the initial battery level of the charging process, the maximum value of the battery level section is all battery level sections with the battery level below 10%, there is no corresponding actual valid historical charging time in the historical charging data, and in the historical charging data, the charging time corresponding to all battery level sections with the maximum value below 10% of the battery level may be, for example, 0 or NULL.

In addition, the battery power interval can be divided according to the specific battery power. Moreover, no matter the battery power interval is divided according to the percentage of the battery power in the total capacity of the battery, or the battery power interval is directly divided according to the specific battery power, the divided interval can be divided according to the actual battery condition. For example, when the battery power interval is divided according to the percentage of the battery power to the total battery capacity, the battery power of each percentage may be used as a battery power interval, for example, 0% to 1% of the battery power is a first interval, 1% to 2% of the battery power is a second interval, and so on, or every two percentages of the battery power may be used as a battery power interval, for example, 0% to 2% of the battery power is a first interval, 2% to 4% of the battery power is a second interval, and so on, or 0% to 1% of the battery power is a first interval, and 1% to 3% of the battery power is a second interval, and so on. The division of the battery power interval is not limited in the present disclosure, as long as all the battery powers that may occur in the battery during the charging process can be divided into a battery power interval.

In step 203, a charging time period required by the vehicle to complete charging is calculated according to the historical charging data and the current remaining battery capacity.

When the charging time required for completing the charging of the vehicle is calculated according to the historical charging data and the current battery residual capacity, the charging time required for each battery capacity interval is determined according to the historical charging data, so that the charging time required from the current battery residual capacity to the charging completion is estimated.

If there is no historical charging time corresponding to a certain battery power interval in the historical charging data, and the charging time corresponding to the battery power interval is needed when the charging time required by the vehicle from the current battery remaining power to the charging completion is calculated, the preset default charging time corresponding to each battery power interval can be used as the charging time corresponding to the battery power interval.

According to the charging time length calculation method provided by the technical scheme, the problem that the charging speed difference between different battery electric quantity intervals is large due to charging characteristics can be fully considered, the time length required by the current charging of the vehicle is calculated according to the historical charging time corresponding to each battery electric quantity interval, so that the calculation precision of the time length required by the charging is greatly improved, the vehicle using experience of a user is improved, and the reasonable planning of the vehicle using time of the user is facilitated.

In one possible embodiment, it should be understood by those skilled in the art that the battery power interval is divided by the actual power of the vehicle battery. For example, in order to protect the safety of charging and discharging the battery and prolong the life of the battery, the upper charging limit and the lower discharging limit of the battery are actually limited when the vehicle battery is charged and discharged, for example, the upper charging limit may be 95% of the total capacity of the battery, and the lower discharging limit may be 7% of the total capacity of the battery, and when the battery capacity is displayed in the vehicle, the actual battery capacity is processed and then displayed to the user with the battery capacity of 0% to 100%, so that when the vehicle is charged, the battery capacity is actually 95% of the total capacity of the battery, but the user sees 100%. Since the battery capacity interval of the battery is divided by the real capacity of the battery, based on the charging upper limit, when the battery capacity interval is divided, the battery capacity interval is only divided by the battery capacity below 95% of the total capacity of the battery, and when the charging time is calculated, the charging time is also the time required for calculating the charging time to 95% of the total capacity of the battery.

In a possible implementation, when the historical charging data corresponding to the vehicle is acquired in step 202 shown in fig. 2, the historical charging data may also be acquired according to a preset time threshold, so as to ensure that the generation time of the acquired historical charging data does not exceed the time threshold from the current time, so that the charging time calculated according to the historical charging data can be more suitable for charging performed under the current environment. In addition, in addition to limiting the acquired historical charging data according to the time threshold, the number of times included in the historical charging data may be used, for example, only the charging data corresponding to the charging process that is closest to the current time in the charging process performed in the past and is acquired by a preset number of times.

Fig. 3 is a flowchart illustrating a vehicle charging period calculation method according to still another exemplary embodiment of the present disclosure. As shown in fig. 3, the method includes step 301 and step 302 in addition to step 201 and step 202 shown in fig. 2.

In step 301, in the case that the historical charging data includes charging data of a plurality of times of charging, an average charging time length of a plurality of historical charging times corresponding to each battery power interval is calculated according to the historical charging data. That is, the average charging time of the battery power interval is calculated according to the historical charging time corresponding to the battery power interval in the process of charging for multiple times, and the average charging time is used as the historical charging time corresponding to the battery power interval.

When calculating the average charging time, only the actually valid historical charging time is averaged. For example, if the historical charging data includes 3 charging processes, and one of the charging processes is performed from the battery with the battery capacity of 15%, and the other two charging processes are performed from the battery with the battery capacity of 10%, the historical charging time corresponding to the battery power interval of 10% -15% of the battery power for example is only valid twice, in the charging process starting from the battery with the battery capacity of 15%, the actual effective historical charging time corresponding to the battery capacity section included in the range of 10% to 15% of the battery capacity is not generated, and therefore, when calculating the average charging time corresponding to the battery power interval included in the range of 10% -15% of the battery power, only the average charging time corresponding to the battery charge interval included in the range is calculated according to the two actually effective historical charging times.

In step 302, a charging time period required by the vehicle to complete charging is calculated according to the average charging time period corresponding to each battery power interval and the current battery remaining power.

Specifically, the process of calculating the charging time required for completing the vehicle charging according to the average charging time corresponding to each battery power interval and the current battery remaining power may be as shown in fig. 4, and includes steps 401 to 404.

In step 401, a first battery capacity interval in which the current battery remaining capacity is located is determined.

In step 402, a first charging duration required from the current remaining battery capacity to the maximum value of the first remaining battery capacity interval is calculated according to the average charging duration corresponding to the first remaining battery capacity interval and the current remaining battery capacity.

For example, the current remaining battery capacity may be 47.5%, when each percentage of the battery capacity is taken as a battery capacity interval, the first battery capacity interval in which the current remaining battery capacity is located may be a forty-eighth interval, the battery capacity ratio range of the forty-eighth interval may be 47% -48%, and the corresponding average charging time period of the forty-eighth interval may beThe first charging period required from the current remaining battery capacity of 47.5% to the maximum value of 48% of the forty-eighth interval may be calculated according to the following equation:

wherein n is the serial number of the next interval of the first battery power interval, soc is the remaining power of the current battery,and the average charging time length corresponding to the n-1 interval.

According to the above formula, the first charging time period required in the forty-eighth interval can be calculated asThat is to say

In step 403, a battery power interval, in which a minimum value in the interval is greater than a maximum value in the first battery power interval, is determined as a second battery power interval, and the average charging time corresponding to the second battery power interval is determined as a second charging time, where the second charging time is one or more.

For example, when the set upper limit of charge is 95% of the battery level and the first battery level section is the forty-eighth section, the second battery level section may be all battery level sections in which the battery level ranges from 48% to 95%. Any battery charge within the second battery charge interval is greater than the maximum value of 48% within the first battery charge interval. The second charging duration may also be the average charging duration corresponding to all battery power intervals included in the second battery power interval.

In step 404, the sum of the first charging period and the second charging period is determined as the charging period required for the vehicle to be charged.

The calculation formula of the charging time period may be as follows:

t is the charging time required for completing the charging of the vehicle, T_n+T_n+1+……+T₉₅The sum of all the second charging periods.

Fig. 5 is a flowchart illustrating a vehicle charging period calculation method according to still another exemplary embodiment of the present disclosure. As shown in fig. 5, the method comprises step 501 and step 502 in addition to step 201, step 301 and step 302 as shown in fig. 3.

In step 501, when a vehicle is in a charging state, a charging pile identifier corresponding to a charging pile used for charging the vehicle is acquired.

In step 502, historical charging data corresponding to the vehicle and the charging pile identifier is obtained, and the historical charging data includes historical charging time corresponding to each battery power interval.

The charging pile identification can be a fixed identification which is actively acquired by the vehicle in the charging process or actively sent by the charging pile, or can be set by the user. For example, in the process of charging the vehicle, a user can actively set the currently used charging pile as a first household charging pile, so that in the process of charging the vehicle, charging-related data can be stored correspondingly to the first household charging pile, and when the first household charging pile is used again for charging later, historical charging data corresponding to the first household charging pile can be acquired, so that the calculation error of charging duration caused by different charging devices is avoided, and the calculation of the charging duration of the vehicle is more accurate.

The charging pile identification can be determined only when the vehicle is in a charging state, but the vehicle charging time can be calculated in real time when the vehicle is in the charging state, and the vehicle can also be calculated when the vehicle is in an uncharged state. Therefore, when the vehicle is in the uncharged state, the history data corresponding to the vehicle may be directly acquired.

Fig. 6 is a flowchart illustrating a vehicle charging period calculation method according to still another exemplary embodiment of the present disclosure. As shown in fig. 6, the method includes step 601 and step 602 in addition to step 201, step 301 and step 302 as shown in fig. 3.

In step 601, an ambient temperature around the vehicle is obtained.

In step 602, historical charging data corresponding to the vehicle and the ambient temperature is obtained, and the historical charging data includes historical charging time corresponding to each battery power interval.

When historical charging data corresponding to the vehicle and the ambient temperature are acquired, historical charging data of which the difference value between the corresponding historical ambient temperature and the acquired ambient temperature is smaller than a preset threshold value may be acquired, or a temperature interval in which the ambient temperature is located may be determined according to the ambient temperature, and then the historical charging data corresponding to the temperature interval may be acquired. The historical ambient temperature corresponding to the historical charging data may be an ambient temperature detected by a corresponding temperature sensor during charging.

Through the technical scheme, the historical charging data generated under the condition that the ambient temperature of the current charging environment is close to the ambient temperature of the current charging environment can be acquired to calculate the charging time, so that the influence of the temperature of the charging environment on the charging time can be further avoided, and the calculation of the charging time of the vehicle is more accurate.

In one possible embodiment, the vehicle charging period calculation method may further include: and displaying the charging time required by the vehicle charging completion. The display method may be any instrument or display screen in the vehicle.
