Vehicle charging and discharging system and power supply terminal thereof

Abstract

The present disclosure provides a vehicle charging and discharging system and a power supply terminal thereof. The system includes a first conversion module, a second conversion module, and a main control module configured to control a plurality of MOS transistors to be conducted and cut off that are arranged inside the first and second conversion modules, for achieving a conversion from an AC voltage to a DC voltage, and achieving a purpose of boost control during the conversion, thereby solving a technical problem that two new energy vehicles of the related art can't be charged therebetween. The present disclosure can also achieve that a power of a drive battery in a vehicle is reverse output to an AC mains power through reverse charging from the second conversion module to the first conversion module, and is compatible with a DC voltage output to take electricity from new energy vehicles.
