The purpose is to provide an electric vehicle charging device capable of preventing arc discharge when disconnecting a power supply connector and a vehicle-side connector. An electric vehicle charging device provided with: a power supply connector (3) for supplying electrical energy from outside the vehicle; a vehicle-side connector (2) for connecting to the power supply connector (3) and positioned in the vehicle; a spring (34) for generating repulsive force in the direction in which the power supply connector (3) and the vehicle-side connector (2) separate; and an engaging part (32) for detecting the disconnection of the power supply connector (3) and the vehicle-side connector (2); wherein the spring (34) generates repulsive force in the direction in which the power supply connector (3) and the vehicle-side connector (2) separate when the engaging part (32) detects that the power supply connector (3) and the vehicle-side connector (2) have disconnected.
