Power distribution method of charging station and terminal

The invention provides a power distribution method of a charging station and a terminal. The current maximum allowable power of the charging station is calculated in real time; acquiring the required current and the vehicle side voltage of the charged vehicles, and calculating the required power of each charged vehicle and the total required power of all the charged vehicles; calculating the power limit of each charging vehicle based on the maximum allowable power, the demand power and the total demand power, and taking the power limit as the power upper limit of the charging pile for charging the corresponding vehicle; the current SOC, the total battery electric quantity and the charging starting time of the charged vehicles are obtained in real time, and the charging ending time of each charged vehicle is calculated in combination with the current charging power of the corresponding charging pile; and grouping the charged vehicles according to the sequence of the charging ending time, and increasing or decr
