Abstract: The present disclosure relates to the technical field of charging devices of electric vehicles, provides a charge and discharge control method, a charging device and a storage medium, the method including: obtaining a residual voltage of an output terminal after a charging circuit is disconnected; controlling a discharge load connected in parallel with the output terminal to form a discharge circuit; performing frequency adjustment and/or width adjustment and/or dead zone adjustment on the residual voltage, so as to accelerate a discharge speed of the discharge circuit. Through the present disclosure, a residual voltage on a charging device side can be released quickly and safely after a charging circuit is disconnected.
