【 英文摘要 】The anti-backflow electric vehicle charging module comprises a power input end, a conversion circuit, a filter circuit, a switch, a diode, a control circuit, a detection circuit and a power output end. The power input end is used for providing power input for the charging module. The conversion circuit is used for converting an input voltage into a target voltage. The filtering circuit is used for filtering the target voltage, and the target voltage is the available voltage of the charging module. The detection circuit is used for detecting the output current of the power output end and sending the output current value to the control circuit. The control circuit is used for receiving the output current value and sending the disconnection or closing command to the switch according to the output current value. The switch is used for disconnecting or closing the circuit in which the received command is located. The diode is used for soft starting and anti-backflow in the charging module. To the embodiment of the invention, the anti-backflow electric vehicle charging module is small in size. The cost is low, and the circuit is simple.
