[0047] Reference Figure 1 , Figure 1This is an optional flow chart of a vehicle charging power control method provided by an embodiment of the present application. The method may include but is not limited to steps S101 to S103:

[0049] Step S102, determining the charging adjustment power corresponding to each vehicle according to the charging status data and grid load data corresponding to each vehicle;

[0050] Step S103, generating a charging control instruction for each vehicle according to the charging adjustment power corresponding to each vehicle, and adjusting the current charging power of each vehicle to the corresponding charging adjustment power according to the charging control instruction for each vehicle.

[0051] In some embodiments, the charging power of each vehicle is dynamically adjusted in combination with the charging status data and grid load data corresponding to multiple vehicles to avoid overloading the grid. Optionally, during peak grid load periods, the current charging power of the vehicle is reduced, and when the grid load is low and the vehicle battery is in good condition, the charging power is increased to speed up the charging process.

[0053] Step S201, collecting charging status data corresponding to each vehicle;

[0054] Step S202, collecting power grid load data.

[0055] In some embodiments, the charging status data may include but is not limited to the current charging power, the current remaining charging time and the current remaining battery charge, etc. The grid load data may include but is not limited to the total grid power supply power and the current grid load, etc.

[0056] In some embodiments, step S102 may include but is not limited to steps S301 to S303:

[0057] Step S301, sorting the vehicles according to the current remaining charging time corresponding to each vehicle to determine the charging priority of each vehicle, wherein the vehicle with the shorter current remaining charging time has the higher corresponding charging priority;

[0058] Step S302, determining the remaining dispatchable charging power of the current power grid according to the total power supply of the power grid and the current power grid load;

[0059] Step S303, determining the charging adjustment power corresponding to each vehicle according to the remaining dispatchable charging power of the current power grid and the charging priority and charging status data of each vehicle.

[0060] In some embodiments, the current remaining dispatchable charging power of the power grid is calculated by the following formula:

[0061] Q=Q s -Q c ;

[0062] Among them, Q is the remaining dispatchable charging power of the current power grid, Q s is the total power supply of the power grid, Q c is the current grid load.

[0063] In some embodiments, vehicles with high charging priority are given priority for intelligent charging, so that when the grid load is peak, their current charging power is maintained to the maximum extent to ensure their charging needs.

[0064] In some embodiments, step S303 may include but is not limited to steps S401 to S405:

[0065] Step S401, obtaining a vehicle with the highest charging priority as the currently adjusted vehicle, and obtaining a current charging power corresponding to the currently adjusted vehicle as the current charging power to be adjusted;

[0066] Step S402, when the current remaining dispatchable charging power of the power grid is greater than the current charging power to be adjusted, the current charging power to be adjusted is determined as the charging adjustment power corresponding to the current adjustment vehicle, and the current remaining dispatchable charging power of the power grid is updated according to the charging adjustment power corresponding to the current adjustment vehicle and the current remaining dispatchable charging power of the power grid;

[0067] Step S403, determining the total charging power corresponding to all vehicles except the currently adjusted vehicle, comparing the updated remaining dispatchable charging power of the current power grid with the total charging power, and generating a comparison result;

[0068] Step S404, determining the charging adjustment power corresponding to the remaining vehicles according to the comparison result, the remaining dispatchable charging power of the current power grid and the charging status data corresponding to the remaining vehicles;

[0069] Step S405, when the current remaining dispatchable charging power of the power grid is less than the current charging power to be adjusted, the charging power is dynamically allocated according to the current remaining dispatchable charging power of the power grid and the current remaining charging time corresponding to each vehicle, and the charging adjustment power corresponding to each vehicle is determined.

[0070] In step S405 of some embodiments, the charging adjustment power corresponding to each vehicle is determined according to the current remaining dispatchable charging power of the power grid and the current remaining charging time corresponding to each vehicle. The charging adjustment power corresponding to each vehicle is calculated by the following formula:

[0071]

[0072] Among them, Q k Adjust the charging power for the kth vehicle, t k is the remaining charging time of the kth vehicle, Q is the remaining dispatchable charging power of the current power grid, M is the number of vehicles including the currently adjusted vehicle, t g is the remaining charging time of the g-th vehicle.

[0073] In some embodiments, step S404 may include but is not limited to steps S501 to S502:

[0074] Step S501: when the comparison result is that the updated remaining dispatchable charging power of the current power grid is greater than the total charging power, the current charging power corresponding to the remaining vehicles is determined as the charging adjustment power;

[0075] Step S502, when the comparison result is that the updated remaining dispatchable charging power of the current power grid is less than the total charging power, the charging adjustment power corresponding to the remaining vehicles is determined according to the updated remaining dispatchable charging power of the current power grid and the current remaining charging time corresponding to the remaining vehicles.

[0076] In step S502 of some embodiments, the charging adjustment power corresponding to the remaining vehicles is calculated by the following formula:

[0077]

[0078] Among them, Q j Adjust the charging power for the jth remaining vehicle, t j is the current remaining charging time of the jth remaining vehicle, Q1 is the updated remaining dispatchable charging power of the current power grid, N is the number of remaining vehicles excluding the currently adjusted vehicle, t i is the current remaining charging time of the i-th remaining vehicle.

[0079] In some embodiments, when the comparison result is that the updated remaining dispatchable charging power of the current power grid is greater than the total charging power, the current charging power corresponding to each of the remaining vehicles is maintained unchanged, and the current charging power corresponding to each of the remaining vehicles is determined as the charging adjustment power.

[0080] In some embodiments, for example, assuming that the total power supply of the power grid is 1000kW, and the monitored current power grid load is 900kW, the current remaining dispatchable charging power of the power grid is: 1000kW-900kW=100kW.

[0081] Vehicle charging situation: Assume that there are 3 electric vehicles being charged, and their relevant information is as follows:

[0082] 1) Vehicle A: 30% charged, 70% remaining, 2 hours remaining, current charging power 50kW;

[0083] 2) Vehicle B: 50% charged, 50% remaining, 1.5 hours remaining, current charging power 60kW;

[0084] 3) Vehicle C: 20% charged, 80% remaining, 3 hours remaining, current charging power 40kW;

[0085] According to the current remaining charging time of vehicles A to C, the charging priority of vehicles A to C is determined, specifically: vehicle B>vehicle A>vehicle C.

[0086] According to the charging priorities of vehicles A to C, vehicle B is determined as the current adjusted vehicle, and the current charging power of vehicle B, 40kW, is obtained as the current charging power to be adjusted. The current charging power to be adjusted is compared with the current remaining dispatchable charging power of the power grid, 40kW<100kW, that is, the current remaining dispatchable charging power of the power grid is greater than the current charging power to be adjusted. The current charging power of the current adjusted vehicle is maintained, and the current charging power to be adjusted is determined as the charging adjustment power corresponding to the current adjusted vehicle, that is, the charging adjustment power of vehicle B is 40kW. According to the charging adjustment power corresponding to the current adjusted vehicle and the current remaining dispatchable charging power of the power grid, the current remaining dispatchable charging power of the power grid is updated. The updated current remaining dispatchable charging power of the power grid is 100kW-60kW=40kW.

[0087] Determine the total charging power corresponding to all vehicles except the currently adjusted vehicle, which is 50kW+40kW=90kW. Compare the updated remaining dispatchable charging power of the current power grid with the total charging power to generate a comparison result of 40kW<90kW, that is, the comparison result is that the updated remaining dispatchable charging power of the current power grid is less than the total charging power. Then, according to the updated remaining dispatchable charging power of the current power grid and the current remaining charging time corresponding to the remaining vehicles, determine the charging adjustment power corresponding to the remaining vehicles. Specifically, the charging adjustment power of vehicle A is: 40kW*[2 / (2+3)]=16kW, and the charging adjustment power of vehicle B is: 40kW*[3 / (2+3)]=24kW.
