[0054] Step 101, obtaining the charging mode selected by the user, the charging current required by the target vehicle, the charging voltage required by the target vehicle, the total power of the charging pile, the number of charging guns of the charging pile, and the temperature of the charging gun line.

[0055] Exemplarily, multiple charging guns can be provided on each charging pile, and multiple charging modules can be provided in each charging gun. The charging module is the smallest charging unit in the present application.

[0056] Step 102, based on the charging mode selected by the user, the charging current required by the target vehicle, the charging voltage required by the target vehicle, the total power of the charging pile, the number of charging guns of the charging pile and the temperature of the charging gun line, calculate the power adjustment target value of the charging gun connected to the target vehicle.

[0057] Exemplarily, step 102 may include:

[0058] The first formula is used to calculate the power adjustment target value of the charging gun connected to the target vehicle.

[0059] The first formula can be:

[0060]

[0061] Among them, P dst represents the power adjustment target value of the charging gun connected to the target vehicle, α user Indicates the coefficient corresponding to the charging mode selected by the user, 0<α user <1,I car Indicates the charging current required by the target vehicle, U car Indicates the charging voltage required by the target vehicle, P Term Indicates the total power of the charging pile, Gnum Indicates the number of charging pile charging guns, β gt Indicates the weight coefficient of charging speed corresponding to the charging gun line temperature, 0<β gt ≤1.

[0062] Step 103: Control the charging power of the charging gun connected to the target vehicle based on the power adjustment target value.

[0063] Exemplarily, step 103 may include:

[0064] When the power adjustment target value is less than or equal to 0, the real-time charging current of the charging gun is directly adjusted to the charging current required by the target vehicle, and the real-time charging voltage of the charging gun is adjusted to the charging voltage required by the target vehicle.

[0065] Exemplarily, step 103 may also include:

[0066] When the power adjustment target value is greater than 0, the product of the charging current required by the target vehicle and the charging voltage required by the target vehicle is calculated and recorded as the charging power required by the target vehicle.

[0067] If the charging power required by the target vehicle is less than the real-time charging power of the charging gun, the difference between the real-time charging power of the charging gun and the charging power required by the target vehicle is calculated and recorded as the first power adjustment amount.

[0068] The charging module removal behavior parameter is calculated based on the first power adjustment amount, the charging mode selected by the user, and the rated power of a single charging module in the charging gun.

[0069] If the charging module removal behavior parameter is less than 0, the charging power of the charging module in the charging gun connected to the target vehicle is reduced so that the total output power of the charging module is the same as the charging power required by the target vehicle.

[0070] If the charging module removal behavior parameter is greater than 0, the number of charging modules in the charging gun connected to the target vehicle is reduced and the charging power of the charging module is adjusted so that the total output power of the charging module is the same as the charging power required by the target vehicle.

[0071] Exemplarily, calculating the charging module removal behavior parameter based on the first power adjustment amount, the charging mode selected by the user, and the rated power of a single charging module in the charging gun may include:

[0072] The second formula is used to calculate the charging module removal behavior parameters.

[0073] The second formula can be:

[0074]

[0075] Among them, R modIndicates the charging module removal behavior parameters, represents the first power adjustment amount, α user Indicates the coefficient corresponding to the charging mode selected by the user, 0<α user <1, P mod Indicates the rated power of a single charging module in a charging gun.

[0076] Exemplarily, the method may further include:

[0077] If the charging power required by the target vehicle is greater than the real-time charging power of the charging gun, the increase in charging power of the charging gun connected to the target vehicle is calculated based on the total power of the charging pile, the total rated power of the charging modules on all charging guns being charged, and the power adjustment target value of each charging gun.

[0078] Based on the increase in the charging power of the charging gun, the output power of the charging gun connected to the target vehicle is increased so that the total output power of the charging gun is the same as the charging power required by the target vehicle.

[0079] Exemplarily, based on the total power of the charging pile, the total rated power of the charging modules on all the charging guns being charged, and the power adjustment target value of each charging gun, calculating the charging power increase of the charging gun connected to the target vehicle may include:

[0080] The third formula is used to calculate the increase in charging power of the charging gun connected to the target vehicle.

[0082]

[0083] in, Indicates the increase in charging power of the charging gun connected to the target vehicle, P RS Indicates the total rated power of the charging modules on all charging guns being charged. Indicates the lth power adjustment target value P dst The power adjustment target value of the charging gun that is greater than 0 and the charging power needs to be increased. m represents the power adjustment target value P dst The number of charging guns that are greater than 0 and whose charging power needs to be increased, P dst Indicates the power adjustment target value of the charging gun connected to the target vehicle.

[0084] Exemplarily, to make the total output power of the charging gun the same as the charging power required by the target vehicle, there are two situations, corresponding to when the charging power is reduced: 1. Increasing the charging power of the charging module in the charging gun connected to the target vehicle; 2. Increasing the number of charging modules in the charging gun connected to the target vehicle and adjusting the charging power of the charging module.

[0085] Specifically, according to the formula Calculate the charging module to increase the behavior parameter R' mod , when R' mod When it is less than 0, the charging power of the charging module in the charging gun connected to the target vehicle is directly increased. mod When it is greater than or equal to 0, the number of charging modules in the charging gun connected to the target vehicle is increased and the charging power of the charging module is adjusted.

[0086] The above cluster charging power allocation method can calculate the power adjustment target value based on the BMS data of the target vehicle, the charging pile data and the user demand data. Subsequently, based on the power adjustment target value, the charging power of the charging gun can be accurately controlled to ensure the accuracy of the charging power allocation, maintain the stability of the power grid, and improve the utilization rate of energy. In addition, the entire process will be calculated and processed periodically at a preset time, so that in the electric vehicle cluster charging scenario, the charging pile can reasonably allocate and regulate the power of each charging terminal based on the vehicle-side BMS data, the pile-side data and the user-side demand data, to ensure the safe, orderly and efficient charging process.
