[0035] The following describes in detail the embodiments of the present invention in conjunction with the accompanying drawings. The principles and processes of the vehicle charging control method, system, device, and storage medium in the embodiments of the present invention are described as follows.

[0036] First, the following terms are necessarily explained:

[0037] Battery charging allowable current. The battery charging allowable current is the current allowed during battery charging, which is affected by the ambient temperature and the battery SOC. The relationship can be referred to Figure 1 , where the full name of SOC is State of Charge, which is the state of charge of the battery in Chinese, also called the remaining charge, representing the ratio of the remaining dischargeable charge of the battery after being used for a period of time or left unused for a long time to the charge of its fully charged state, usually expressed as a percentage. It is represented by one byte, that is, two-digit hexadecimal (the value range is 0-100), meaning the remaining charge is 0%-100%. When SOC = 0, it means the battery is fully discharged, and when SOC = 100%, it means the battery is fully charged. The SOC (state of charge) of the battery reflects the actual available charge of the battery, and it is a very important indicator during the operation of an electric vehicle. As Figure 1 shown, under the condition that the battery cell temperature is 20 degrees Celsius, the battery charging allowable current is different as the SOC rises from 5% to 60%. At 5% and 20%, it reaches a maximum of 200A. Subsequently, as the SOC increases, the battery charging allowable current gradually decreases, and the vehicle charging control method of the present application precisely utilizes this characteristic.

[0038] Secondly, the vehicle control method of the present application is described. Referring to Figure 2 , the present invention provides a vehicle charging control method for controlling the charging current of the battery and the heating current of the heating system, enabling the vehicle to charge more quickly and energy-efficiently in a low-temperature environment. The method may include the following steps:

[0039] S1. Receive the first user input instruction;

[0040] Specifically, in the embodiments of the present application, the user input instruction can be an instruction input through a button on the vehicle's internal central control. By inputting the instruction, the vehicle can be controlled to enter different charging modes. Or, a network connection can be established first through the network or cloud platform, and a wireless connection between the mobile device and the vehicle to be charged can be established, and the vehicle can be controlled to enter different charging modes through the wireless device. Further, in the embodiments of the present application, the first user input instruction is a fast charging instruction. After the controller receives this instruction, it enters the fast charging mode. In this mode, the battery can be charged with the maximum current output by the charging pile, the maximum charging allowable current, or the current optimized by the algorithm.

[0041] S2. Obtain the output current of the charging pile, the maximum heating current of the heating system, and the current charging allowable current according to the first user input instruction;

[0042] In some embodiments of the present application, the current charging allowable current of the battery can reflect the maximum current allowed for battery charging at a certain temperature. Different temperatures of the battery cells result in different charging allowable currents. In the embodiments of the present application, a relationship table of the current charging allowable current, the cell temperature of the battery, and the SOC of the battery can be pre-input to the electronic control unit. The electronic control unit can obtain the current charging allowable current of the battery by acquiring the cell temperature of the battery and the SOC of the battery from the table; the output current of the charging pile is one of the fixed parameters of the charging pile. In the embodiments of the present application, the output current of the charging pile can be obtained through data interaction between the vehicle and the charging pile; the maximum heating current is one of the fixed parameters of the vehicle heating system and can be obtained through the electronic control unit of the vehicle. After receiving the fast charging instruction input by the user, the vehicle electronic control unit can obtain the maximum current of the heating system and the current charging allowable current through the vehicle CAN bus. The vehicle electronic control unit can also obtain the output current of the charging pile through data interaction with the charging pile. Different charging piles have different output currents. By obtaining the output currents of different charging piles through data interaction in the present application, the accuracy of charging control can be further improved.

[0043] S3. Adjust the charging current and the heating current according to the output current of the charging pile, the maximum heating current, and the current charging allowable current.

[0044] In some embodiments of the present application, since the output voltage of the charging pile is usually a rated value, the output current of the charging pile can reflect the maximum power of the charging pile during charging. During the charging process of the vehicle, the magnitudes of the output current of the charging pile and the current charging allowable current of the battery will affect the electronic control unit's control of the charging current flowing to the battery and the current flowing to the heating system. According to the comparison result between the output current of the charging pile and the current charging allowable current, the charging current of the battery and the current of the heating system can be adjusted. The charging battery and the heating current are adjusted based on different comparison results to minimize the charging time of the battery or save the charging energy consumption of the battery.

[0045] Further, referring to Figure 3 , the adjusting the charging current and the heating current according to the output current of the charging pile, the maximum heating current, and the current charging allowable current may include:

[0046] S31. If the output current of the charging pile is less than or equal to the current charging allowable current, adjust the charging current to the output current of the charging pile;

[0047] Specifically, if the output current of the charging pile is less than or equal to the current charging allowable current of the battery, at this time, since the output current of the charging pile is still not enough to reach the current charging allowable current of the battery, in order to accelerate the battery charging and shorten the charging time, the electronic control unit can adjust the charging current of the battery to the output current of the charging pile. At the same time, since all the output current of the charging pile is used for battery charging, the current of the heating system is 0 and the heating system does not work.

[0048] S32. If the output current of the charging pile is greater than the current charging allowable current, calculate the difference between the output current of the charging pile and the current charging allowable current.

[0049] Specifically, if the output current of the charging pile is greater than or equal to the current charging allowable current of the battery, at this time, if all the output current of the charging pile is provided for battery charging, since the current is greater than the current charging allowable current of the battery, if the electronic control unit controls the charging current to be the output current of the charging pile, the battery life will be reduced. Therefore, in this case, the electronic control unit can control that the current for charging the battery can only be at most the same as the current charging allowable current of the battery, and the difference between the output current of the charging pile and the charging current is used as the heating current of the heating system.

[0050] S33. Compare the maximum heating current with the difference to obtain a comparison result.

[0051] Specifically, in the embodiment of the present application, when the maximum heating current is less than or equal to the difference between the output current of the charging pile and the current charging allowable current, it means that the output current of the charging pile can simultaneously provide the battery with the maximum charging allowable current for charging and provide the heating system with the maximum heating current to heat the battery; if the maximum heating current is greater than the difference between the output current of the charging pile and the current charging allowable current, it means that the output current of the charging pile cannot simultaneously provide the battery with the maximum charging allowable current for charging and provide the heating system with the maximum heating current to heat the battery. At this time, it is necessary to reasonably adjust and distribute the charging current of the battery and the heating current of the heating system through an algorithm.

[0052] S34. Adjust the charging current and the heating current according to the comparison result.

[0053] Specifically, in the embodiment of the present application, when the maximum heating current is greater than the difference between the output current of the charging pile and the current charging allowable current, since the output current of the charging pile is not enough to provide the maximum heating current for the heating system and the charging allowable current for the battery, the electronic control unit can aim to fully charge the battery in the shortest time and reasonably distribute the charging current and the heating current; the distributed charging current is lower than the charging allowable current, and the heating current of the heating system is between 0 and the maximum heating current. By charging and heating simultaneously, the battery charging is accelerated.

[0054] Further, adjusting the charging current and the heating current according to the comparison result may include:

[0055] S341. If the difference between the output current of the charging pile and the first current parameter is greater than or equal to the maximum heating current, adjust the heating current to the maximum heating current;

[0056] Specifically, in the embodiment of the present application, when the output current of the charging pile is greater than the current charging allowable current of the battery, and the difference between the output current of the charging pile and the current charging allowable current of the battery is greater than or equal to the maximum heating current of the heating system, in order to make the charging speed the fastest, the vehicle electronic control unit can control the heating system to heat the battery with the maximum heating current, control the charging current to the current charging allowable current, and minimize the heating and charging time.

[0057] S342. If the difference between the output current of the charging pile and the first current parameter is less than the maximum heating current, adjust the charging current and the heating current through an algorithm.

[0058] Specifically, in the embodiment of the present application, when the output current of the charging pile is greater than the current charging allowable current of the battery, and the difference between the output current of the charging pile and the current charging allowable current of the battery is less than the maximum heating current of the heating system, since the output current of the charging pile is not sufficient to provide the maximum charging allowable current for the battery and also provide the maximum heating current for the heating system at the same time, at this time, the charging current of the battery will not reach the current charging allowable current of the battery, and the heating system will not reach the maximum heating current either. Instead, in order to minimize the charging time, within the range of the current charging allowable current and the maximum heating current, the controller can calculate through a specific algorithm to adjust the charging current of the battery and the heating current of the heating system under the condition of maximizing power. Refer to Figure 4 , in Figure 4 , when the current charging allowable current of the battery is 60A, the output current of the charging pile of the charging pile is 50A, and the maximum heating current of the heating system is 20A. At this time, since the current of the charging pile is 50A, which is less than the current charging allowable current of the battery, the heating current is 0 at this time, and the charging current is 50A. When the output current of the charging pile of the charging pile is 100A, since the output current of the charging pile of the charging pile is greater than the sum of the current charging allowable current of the battery and the maximum heating current, the charging pile charges the battery with the current charging allowable current of the battery and controls the heating system to heat the battery with the maximum heating current. When the output current of the charging pile of the charging pile is 70A, at this time, the output current of the charging pile of the charging pile is greater than the current charging allowable current of the battery, and the difference between the output current of the charging pile and the current charging allowable current of the battery is less than the maximum heating current of 20A. At this time, the weighted coefficient obtained through the genetic algorithm is 0.75. Therefore, the optimized heating current is 15A, and the charging current is the difference between the output current of the charging pile of the charging pile and the heating current, that is, 55A.

[0059] Further, the adjusting of the charging current and the heating current by the algorithm may include:

[0060] Obtain the ambient temperature of the vehicle;

[0061] Obtain a weighting coefficient based on the ambient temperature and the current allowable charging current;

[0062] Adjust the heating current and the charging current according to the weighting coefficient and the maximum heating current.

[0063] In the embodiment of the present application, the core of the algorithm is to determine the weighting coefficient. The electronic control unit can obtain the ambient temperature of the vehicle and the current allowable charging current, and take the shortest charging time for battery charging as the objective function. The weighting coefficient is calculated through a genetic algorithm. Since the charging current cannot be greater than the current allowable charging, the value range of the weighting coefficient is 0-1. The heating current can be obtained by multiplying the maximum heating current by the weighting coefficient, and the charging current can be obtained by subtracting the heating current from the output current of the charging pile.

[0064] In addition, in some other embodiments of the present application, the vehicle charging control method may further include:

[0065] Receive a second user input instruction;

[0066] Obtain the current allowable charging current and the ambient temperature of the battery according to the second user input instruction;

[0067] Predict the longest charging time of the battery according to the current allowable charging current and the ambient temperature;

[0068] If the predicted longest charging time is greater than the target charging time, adjust the charging current and the heating current.

[0069] Specifically, in the embodiment of the present application, the second user input instruction is an energy-saving charging instruction. After receiving the user input energy-saving charging instruction, the vehicle electronic control unit can obtain the current allowable charging current of the battery by obtaining the core temperature of the battery and the SOC of the battery in the table, predict the longest charging time through the current allowable charging current and the ambient temperature, and set a target charging time, which is the time required for the battery to be fully charged, and this time must be a time that meets the commodity nature, such as it can be set to 10 hours. If the longest charging time is greater than the target charging time, the electronic control unit can appropriately adjust the charging current and the heating current to make the battery fully charged within the target charging time of 10 hours with the smallest possible charging current and heating current.

[0070] Further, if the longest charging time is less than or equal to the target charging time, the electronic control unit can adjust to use the current charging allowable current as the charging current, and set the current of the heating system to 0 to charge the vehicle battery.

[0071] Further, in some other embodiments of the present application, the adjustment of the charging current and the heating current includes:

[0072] Obtain the ambient temperature of the vehicle;

[0073] Obtain a weighting coefficient according to the ambient temperature, the current charging allowable current, and the target charging time;

[0074] Adjust the heating current and the charging current according to the weighting coefficient and the maximum heating current.

[0075] Specifically, in the embodiments of the present application, different from fast charging, the algorithm for adjusting the current in the energy-saving mode requires not only obtaining the ambient temperature of the vehicle and the current charging allowable current, but also setting the charging time. Taking the minimum charging current to complete the battery charging within the set time as the objective function, the weighting coefficient is obtained by calculating through the genetic algorithm. The heating current can be obtained by multiplying the maximum heating current by the weighting coefficient, and the charging current can be obtained by subtracting the heating current from the output current of the charging pile.
