Charging equipment for electric vehicle, power supply method and power supply system using the same

Abstract

A charging equipment for an electric vehicle, a power supply method and a power supply system using the same are provided. The charging equipment includes a main control module and an auxiliary startup module. The main control module includes a processing circuit and a relay. The relay is connected to the processing circuit and is used to connect to the electric vehicle. The auxiliary startup module includes a power line port and a charging protocol controller. The charging protocol controller is connected to the power line port. The charging protocol controller is used to detect whether the power line port is connected to a DC power source. The DC power source supplies power to the main control module via the power line port to enable the main control module, so that the electric vehicle supplies power to a power grid or a household appliance through the main control module.
