The invention provides an anti-backflow electric vehicle charging module, a charging pile and a charging system. 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 the input voltage into a target voltage; the filter circuit is used for filtering the target voltage, and the target voltage is 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 an opening or closing instruction to the switch according to the output current value; the switch is used for opening or closing the circuit where the switch is located according to the received instruction; the diode is used for soft starting and backflow prevention in the charging module. According to the embodiment of the invention, the anti-backflow electric vehicle charging module is small in size, low in cost and simple in circuit.
