A mains supply method, including, upon a mains failure, detecting whether a quantity of remaining electricity of the backup mains supply system is not enough for supporting a critical load of the mains supply system to work properly for a time T; if yes, detecting whether a quantity of feedable electricity of an electric vehicle of the mains supply system is greater than zero; and if yes, controlling one or more electric vehicles that can provide feedable electricity and the backup mains supply system to jointly supply electricity to the critical load. Technical solutions provided in the embodiments of the present disclosure can keep, upon the mains failure, the critical load working as long as possible to wait for the mains to restore, that is, can improve working stability of the critical load.
