Abstract

The invention discloses a charge and discharge system and a control method thereof. The system includes a charge and discharge interface device, a control device, a fast and slow charge and dischargesystem control device and a grid access device. The control device is configured to control the grid access device, and the fast and slow charge and discharge system control device performs charging and discharging through the charge and discharge interface device. The control device controls a contactor of the fast and slow charge and discharge system control device to be closed when the charge and discharge interface device is connected to a single gun and the charge and discharge required power exceeds a set threshold and controls the contactor in the fast and slow charge and discharge system control device to be open when the charge and discharge interface device is connected to the single gun and the charge and discharge required power is lower than the set threshold or the charge anddischarge interface device is connected to double guns. Therefore, two-way charging and discharging of a double-gun charge interface can be achieved.

Description

technical field [0001] The present application relates to the technical field of new energy vehicle charging, in particular to a charging and discharging system and a control method thereof. Background technique [0002] This section is intended to provide a background or context to the embodiments of the application that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Vehicle to grid (V2G) technology of electric vehicles refers to the technology that electric vehicles send power to the grid. Its core idea is to use a large number of electric vehicle energy storage as a buffer for the grid and renewable energy. Vehicle-to-grid technology is attracting widespread attention. Through V2G, the problems of low grid efficiency and fluctuations in renewable energy can be alleviated to a large extent, and it can also create benefits for electric vehicle users. [0004] During the charging process of the exi...
