Abstract

A power supply system includes a convertor and a power supply control device. The power supply control device includes a first power supply interface configured to connect to a mains power interface to obtain electric power, and a second power supply interface configured to supply power to a power tool battery pack. The convertor includes a first conversion interface and a second conversion interface. The first conversion interface is connected to an electric vehicle, the second conversion interface is connected to the first power supply interface, so that the power supply control device connects to the convertor to connect to the electric vehicle to obtain electric power. The convertor can also communicate with the power supply control device and the electric vehicle to achieve power matching of the power supply system based on the communication.
