Self-adaptive control two-way electric vehicle charging equipment and method

The invention discloses a self-adaptive control bidirectional electric vehicle charging device and method, and belongs to the field of batteries, the charging device comprises a direct current charging gun, a charging module and a controller, the direct current charging gun is connected with the charging module, and the controller is connected with a control signal port of the direct current charging gun and the charging module. The working mode of the bidirectional charging module is determined according to the power level, and high-efficiency voltage regulation output is adaptively calculated according to the charging power, so that the working parameters of the charging module are determined, and charging in the optimal state is completed. Meanwhile, the battery states of the two parties are detected through communication, and when the charging and discharging states and temperature of the batteries exceed normal values, charging equipment is protected and stops charging; the charging equipment has triple
