Detailed Description

In order to explain technical contents and structural features of the present invention in detail, the following description is made with reference to the embodiments and the accompanying drawings.

The invention provides a power supply method for a new energy automobile, wherein the new energy automobile comprises an automobile body and a power utilization module 200, such as a three-module. The power supply method of the new energy automobile comprises the following steps: the method comprises the steps of providing a fixed battery pack 10 capable of being plugged in and a standardized shared battery module 20, initially placing the shared battery module 20 in a shared battery cabinet, fixedly installing the fixed battery pack 10 in the new energy automobile, and enabling the fixed battery pack 10 to be used for driving a preset mileage of the new energy automobile. The new energy automobile (the power utilization module 200) is independently powered through the fixed battery pack 10, and the residual capacity of the fixed battery pack 10 is monitored in real time. When the remaining capacity of the fixed battery pack 10 is reduced to a preset threshold, a plurality of shared battery modules 20 are detachably mounted on the new energy vehicle, and the new energy vehicle is powered by the shared battery modules 20 (as shown in fig. 1). After the power supply requirement is met or the use is finished, the shared battery module 20 is dismounted from the new energy automobile and returned to the shared battery cabinet, and the shared battery module 20 is charged through the shared battery cabinet so as to realize cyclic utilization. Specifically, it is preferable to charge the shared battery module 20 at night during the peak of power level-valley. Therefore, invalid occupation of the shared battery module 20 and long-term stop occupation of the shared battery module 20 are avoided, the sharing characteristic of the shared battery module 20 is ensured, the use frequency of the shared battery module 20 is improved, at the moment, an operator can design a simple charging mode to charge, profit is realized, meanwhile, waste is also avoided, and the method is more green and environment-friendly.

Specifically, a plurality of connectors for electrically connecting the shared battery module 20 are provided in advance in the new energy vehicle. The shared battery module 20 is installed by installing a plurality of standardized drawers matched with the shape and the size of the shared battery module 20 in the new energy automobile, and each standardized drawer can be provided with one shared battery module 20.

The preset mileage is the normal daily driving mileage of most new energy vehicles so as to meet the short-distance commuting requirements of users. Preferably, the preset mileage is 100-360 kilometers, so that the requirement of a user on short-range commuting can be met, the dead weight of the new energy automobile is reduced, the manufacturing cost of the new energy automobile is reduced, and the purchase cost of the user is reduced. In specific implementation, the fixed battery pack 10 with the corresponding capacity can be set according to the preset mileage and the energy consumption of the new energy automobile, and the fixed battery pack 10 is not limited to a specific capacity value. Wherein the remaining capacity of the stationary battery pack 10 can be obtained by a battery management system BMS (prior art).

The preset threshold is an electric quantity value which is greater than zero and can provide a certain mileage for the new energy automobile, so that a user can reach the nearest shared battery cabinet to rent the shared battery module 20 before the electric quantity of the fixed battery pack 10 is exhausted, and the new energy automobile can be supplied with power through the shared battery module 20. Preferably, each shared battery module 20 is a 5KW to 30KW shared battery module, the shared battery module 20 is relatively light in weight, and is convenient to take and mount/dismount, and the number of the shared battery modules can be flexibly adjusted according to the endurance requirement, for example, when the endurance mileage is long, 6 to 7 shared battery modules 20 can be selected, and when the endurance mileage is short, 1 to 2 shared battery modules 20 can be selected, which not only reduces the rental cost, but also prevents unnecessary occupation of the shared battery modules 20.

In this embodiment, the output current of the shared battery module 20 is also monitored in real time, and when the output current of the shared battery module 20 is greater than the supply current required by the new energy automobile, the shared battery module 20 is controlled to charge the fixed battery pack 10. For example, when a new energy automobile runs on a downhill road section, the required supply current is small, and at this time, the fixed battery pack 10 is charged through the shared battery module 20, so that waste of electric energy can be avoided, and the electric quantity of the fixed battery pack 10 can be supplemented. When the output current is smaller than the required power supply current of the new energy automobile, the fixed battery pack 10 and the shared battery module 20 are controlled to cooperate to supply power to the new energy automobile. For example, when a new energy automobile runs on an uphill road, the required power supply current is large, and at this time, the fixed battery pack 10 and the shared battery module 20 cooperate to supply power to the new energy automobile, so that the power consumption requirement of the new energy automobile is met. Or, when the required driving mileage is short, the user rents only a small number of shared battery modules 20, for example, one or two shared battery modules 20, and at this time, the power consumption requirement of the new energy vehicle may not be met if the shared battery module 20 alone supplies power to the new energy vehicle, and through the mode that the fixed battery pack 10 and the shared battery module 20 cooperatively supply power, the renting cost can be reduced and unnecessary occupation of the shared battery module 20 can be avoided. The output current of the shared battery module 20 can be obtained by the battery management system BMS (prior art), the output current of the shared battery module 20 is compared with the required supply current of the new energy vehicle by the controller 50, and a corresponding instruction is output according to the comparison result to enable the shared battery module 20 to charge the fixed battery pack 10 or enable the fixed battery pack 10 and the shared battery module 20 to cooperate to supply power to the new energy vehicle.

Specifically, the sensor 30 is arranged in the new energy vehicle to sense the access of the shared battery module 20, and the sensor 30 is in communication connection with the controller 50 of the new energy vehicle. The current output of the fixed battery pack 10 is controlled by providing a control switch 40, and the control switch 40 is in communication connection with a controller 50 (shown in fig. 2) of the new energy vehicle. When the sensor 30 senses that the shared battery module 20 is connected, an access signal is fed back to the controller 50, and at this time, the controller 50 controls the control switch 40 to be turned off to stop the fixed battery pack 10 from supplying power to the new energy vehicle. When the fixed battery pack 10 and the shared battery module 20 need to supply power cooperatively, the controller 50 controls the control switch 40 to be turned on, so that the fixed battery pack 10 supplies power to the new energy automobile again.

In one embodiment, when the required driving range is reduced to the range threshold, the remaining capacity of the shared battery module 20 is obtained, and if the remaining capacity of the shared battery module 20 is greater than the driving range required by the range threshold, the shared battery module 20 is controlled to charge the fixed battery pack 10. That is, when the cruising requirement is nearly completed, the remaining electric quantity of the shared battery module 20 is charged to the fixed battery pack 10, so that the new energy vehicle can be supplemented with electric quantity during the driving process, and the next cruising can be completed.

Specifically, in this embodiment, the shared battery module 20 is connected to the fixed battery pack 10 by a wire, and the on-off switch 60 is disposed on a connection line between the shared battery module 20 and the fixed battery pack 10, the on-off switch 60 is connected to the controller 50 in a communication manner, so that the controller 50 controls the on-off switch 60 to be turned on when the required driving range is reduced to the mileage threshold and the remaining capacity of the shared battery module 20 is greater than the driving range capacity required by the mileage threshold, so as to charge the fixed battery pack 10 with the shared battery module 20 (as shown in fig. 3); otherwise, the on-off switch 60 is controlled to be turned off, at which time the electrical connection between the shared battery module 20 and the stationary battery pack 10 is broken.

Compared with the prior art, the invention ensures that the endurance mileage of the new energy automobile can meet the endurance requirement of a user under special conditions on the premise of not increasing the original weight and price of the new energy automobile, even reaches the same level as that of a fuel oil automobile, reduces the manufacturing cost of the new energy automobile and lightens the purchase cost of the user. Moreover, the invention adopts the shared battery module 20 to realize endurance, can realize instant use and replacement, and has good user experience because the user does not occupy a certain shared battery module 20 for a long time, and the user does not need to face the quality problem and the battery aging problem of the shared battery module 20. Meanwhile, the sharing mode also avoids a user from unnecessarily occupying a certain shared battery module 20 for a long time, improves the use frequency of the shared battery module 20, avoids resource waste and is more environment-friendly.

The present invention has been described in connection with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, and is intended to cover various modifications, equivalent combinations, which are made in accordance with the spirit of the present invention.
