Poor control performance of flexible charging output power fluctuation of electric vehicles will reduce the charging transmission efficiency of electric vehicles. In order to improve the stability of output power, a flexible charging control algorithm for electric vehicles in the platform area based on semi-supervised integrated pruning algorithm is proposed. Fitting the relationship between temperature and battery capacity, analyzing the active power of flexible charging of electric vehicles in the platform area, and constructing the flexible charging load model of electric vehicles in the platform area; According to this model, the stable state of flexible charging is adjusted, and the flexible charging control of electric vehicle group is realized. The experimental results show that the control performance of the proposed algorithm is strong, and the active power load value of the flexible charging process of the electric vehicle group in the station area is close to the expected power load value.
