Detailed Description

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

The following describes a method and apparatus for controlling charge of a vehicle, a storage medium, and a vehicle according to embodiments of the present invention with reference to the accompanying drawings.

Fig. 1 is a flowchart of a charge control method of a vehicle according to an embodiment of the present invention.

As shown in fig. 1, the present invention proposes a charge control method of a vehicle, the charge control method comprising the steps of:

s10, acquiring a charging expected parameter and an original charging map of the vehicle.

Specifically, for example, in a vehicle provided with a central control screen, a charging desired parameter of the vehicle may be obtained through the central control screen, that is, a user may input a charging desired parameter desired by the user through the central control screen. The charging expected parameters may include a charging expected time and a charging target SOC, for example, the current battery SOC of the vehicle is 30%, and the distance from the destination is at least 50% of the electric quantity, so that the user can set the charging target to 50%, and thus the vehicle can be guaranteed to travel to the destination, and charging is performed after reaching the destination, so that charging cost in the charging pile can be reduced, and the expenditure of the user can be saved. In addition, in the process of charging the vehicle, the user can set the charging time expected by the user, namely the charging expected time, and sometimes the performance and the service life of the battery are considered, so that the user can more hopefully reduce the charging current, and the loss of the battery caused by the charging current is reduced, and the charging time can be prolonged.

In this step, an original charging map of the vehicle needs to be obtained, where the original charging map may be directly obtained from a BMS (Battery management system) of the vehicle, and it may be understood that the original charging map may be factory set for the vehicle, and information such as charging times corresponding to different charging targets, charging currents corresponding to different SOC intervals of the Battery and the like are marked in the original charging map.

S20, determining a charging map to be executed of the vehicle according to the charging expected parameters and the original charging map.

Specifically, after the charging expected parameter is obtained, the original charging map may be corrected and adjusted according to the charging expected parameter, so that the charging map to be executed after correction and adjustment can meet the charging requirement of the user. It is understood that the map to be charged is temporarily used, which may be temporarily stored in the BMS, and then deleted after the current vehicle charging is completed, so as to reduce the occupation of the storage space in the BMS.

And S30, sending the to-be-executed charging map to the charging pile so that the charging pile charges the vehicle according to the to-be-executed charging map.

Specifically, after the to-be-executed charging map of the vehicle is determined, the to-be-executed charging map may be sent to the charging pile through the BMS of the vehicle, so that the charging pile may output a corresponding charging parameter to the vehicle according to the to-be-executed charging map, specifically, a table may be checked in the to-be-executed charging map according to the battery SOC of the vehicle to obtain the corresponding charging parameter, and then current/voltage is output to complete charging of the vehicle according to the found charging parameter. It can be appreciated that, because there may be a difference in the charging parameters corresponding to different battery SOCs, the present embodiment may acquire the battery SOC of the vehicle once every preset time, so as to timely and accurately update the charging parameters of the vehicle, and the charging post may also feed back the relevant charging parameters to the BMS of the vehicle during the charging process of the vehicle.

More specifically, as shown in fig. 2, the charging control method of the vehicle in the present embodiment may be applied to one central computing unit 20, the central computing unit 20 may be disposed on the vehicle and connected to the custom input terminal 10 and the BMS30, respectively, the charging desired parameters may be obtained from the custom input terminal 10, and the original charging map may be obtained from the BMS30, after determining the charging map to be performed based on the charging desired parameters and the original charging map, the charging map to be performed may be sent to the charging post 40 through the BMS30, so that the charging post 40 may be capable of charging the vehicle, and the charging post 40 may also be capable of feeding back corresponding charging parameter information to the BMS30, so that the BMS30 may be capable of performing fault handling, parameter adjustment, and other charging management on the charging of the vehicle.

In some embodiments of the present invention, as shown in fig. 3, determining a charging map to be performed for a vehicle according to a charging desired parameter and an original charging map includes:

S301, determining the original charging time of the vehicle according to the charging target SOC and the original charging map.

Specifically, the correspondence between the charge target SOC and the charge time is stored in the original charge map, so after the charge target SOC is determined, the original charge time required if charging is performed in accordance with the charge information corresponding to the original charge map can be determined.

S302, calculating correction parameters according to the original charging time and the expected charging time.

Specifically, if the original charging time is different from the charging expected time, in order to improve the use experience of the user, the charging expected time may be taken as a reference, and the corresponding charging parameters may be modified so that the vehicle can complete charging according to the charging expected time. Specifically, the correction parameter may be calculated according to the original charging time and the charging expected time, and more specifically, the quotient of the original charging time and the charging expected time is taken as the correction parameter, and in this embodiment, the correction parameter is calculated by taking the charging expected time as a reference, and since the original charging time can be obtained, the correction parameter between the original charging time and the charging expected time is calculated, and then the charging parameter is adjusted by using the correction parameter, so that the vehicle can meet the requirement of the charging expected time after charging by using the adjusted charging parameter.

S303, correcting the original charging map according to the correction parameters to determine the charging map to be executed.

Specifically, after the correction parameter is calculated, the original charging map may be corrected according to the correction parameter, specifically, the charging current corresponding to each SOC interval in the original charging map may be corrected, for example, the correction parameter may be multiplied by the charging current to obtain a new charging current, and then the new charging current, the corresponding SOC interval, the corresponding charging time and other information form the charging map to be executed.

In this embodiment, correcting the original charging map according to the correction parameter includes: multiplying the correction parameter by the charging parameter corresponding to each SOC interval in the original charging map to obtain a corrected charging parameter; and updating the charging parameters corresponding to each SOC interval in the original charging map according to the corrected charging parameters.

Specifically, for example, assuming that the battery SOC of the vehicle is 30% when the user arrives at the charging station, the user plans to charge the battery to 100%, the charging time is approximately 0.75h calculated from the original charging map, and the user intends to move around the charging station for 3 hours, at this time, if the user does not perform the custom charging, the vehicle may face a occupation fee of 2.25 hours after the charging, and thus the user inputs the charging desired time of 3 hours at the custom charging module, and the charging target SOC is 100%. The correction parameters are calculated to obtain correction parameters λ=0.75/3=0.25, and the original charging maps captured by the central computing unit in the BMS are multiplied by 0.25 for each value. More specifically, assuming that charging is performed from 30% -100% in accordance with the original charging map, the specific body will be charged with a charging current of 200A in 30% -50% of the battery SOC; charging with a charging current of 160A when the SOC of the battery is 50% -70%; charging with 140A of charging current when the SOC of the battery is 70% -80%; charging with a charging current of 80A when the SOC of the battery is 80% -90%; the battery SOC is in the range of 90% -100% charged with a charging current of 40A. After the correction is carried out by the obtained correction parameters, the battery SOC is particularly in 30% -50%, and charging is carried out by adopting a charging current of 50A; charging with a charging current of 40A when the SOC of the battery is 50% -70%; charging with a charging current of 35A when the SOC of the battery is 70% -80%; charging with a charging current of 20A when the SOC of the battery is 80% -90%; the battery SOC is in the range of 90% -100% charged with a 10A charging current. The corrected charging map is the charging map to be executed in the embodiment, and the charging map to be executed is input into the BMS of the vehicle, so that the BMS can exchange handshaking with the charging pile, the charging pile charges according to the charging map to be executed, the charging time is close to the set charging time for 3 hours according to the user requirement, the charging requirement of the user is met, and the occupation expense is saved.

In some embodiments of the present invention, the charge control method further includes: and when the correction parameter is greater than or equal to the preset parameter, determining the original charging map as the charging map to be executed of the vehicle.

Specifically, in the process of correcting the original charging map using the correction parameters, since the user sometimes needs to accelerate the charging speed, it is necessary to judge and limit the battery performance or charging safety. In this embodiment, preset parameters are introduced and compared with correction parameters, and when the correction parameters are greater than or equal to the preset parameters, it means that if correction is performed according to the correction parameters, there may be a potential safety hazard or the like, so that the original charging map may be determined as a charging map to be performed on the vehicle, that is, whether the charging pile is controlled or the charging of the completed vehicle is performed according to the original charging map. In some embodiments, the preset parameter may be 1, that is, it may be understood that the charging parameter corresponding to the original charging map is the maximum charging parameter that can be executed by the battery of the vehicle, and charging according to the original charging map is fastest, so that the user can only reduce the charging speed and prolong the charging time, so that the correction parameter is generally smaller than 1 in this case, and if the correction parameter is calculated to be greater than or equal to 1, the vehicle is directly charged according to the original charging map.

In this embodiment, the charge control method further includes: and sending reminding information that the charging map to be executed is the original charging map to the vehicle.

Specifically, after the vehicle does not correct the original charging map according to the needs of the user and still uses the charging map to be executed as the original map, corresponding reminding information needs to be sent to remind the user. Alternatively, the reminding manner of the reminding information may include a sound reminding, an image reminding, etc., and the content of the reminding information may include information such as a reason for still executing the original charging map, a danger if the original charging map is forcedly corrected and executed, and a charging time according to the original charging map. Of course, in some embodiments, the maximum output current of the charging pile may be set as a limiting value, and if the charging current corresponding to the SOC interval in the corrected charging map to be executed is found to be greater than the limiting value, the original charging map is still used as the charging map to be executed, and reminding is performed.

In summary, the vehicle charging control method in the embodiment of the invention can greatly improve the use experience of a user and the flexibility of vehicle charging, simultaneously improve the service life of a vehicle battery and ensure the charging safety of the vehicle.
