Abstract

The invention relates to a vehicle to grid (V2G) intelligent charging and discharging system, which comprises a monitoring center, a background management subsystem, an intelligent ammeter, a bidirectional and intelligent charging and discharging device, a charging and discharging terminal, an electric vehicle, a transformer and a power grid. The monitoring center is connected with the background management subsystem; the bidirectional and intelligent charging and discharging device is respectively connected with the background management subsystem, the intelligent ammeter, and the charging and discharging terminal; the charging and discharging terminal is connected with the electric vehicle; the intelligent ammeter is connected with the transformer; and the transformer is connected with the power grid. Compared with the prior art, the technology employed in the invention enables bidirectional interaction and exchange of the energy of an electric vehicle between a controlled state and a power grid to be realized; besides, the V2G intelligent charging and discharging system has advantages of energy conservation and environmental protection.

Description

technical field [0001] The invention relates to an electric vehicle charging and discharging system, in particular to a V2G intelligent charging and discharging system. Background technique [0002] V2G (electric vehicle grid or vehicle to grid) describes a new grid technology. Electric vehicles not only serve as users and power consumers, but also connect to the grid as green mobile energy storage units to provide power for the grid when electric vehicles are idle. , to realize the two-way interaction and exchange between the energy of the electric vehicle and the grid under control. [0003] In recent years, with the rapid development of pure electric vehicle technology and power lithium-ion battery technology, large-scale centralized charging stations have begun to appear. During the 2008 Beijing Olympic Games, the first centralized charging station in China was built, which can meet the power battery charging needs of 50 pure electric buses. The 2010 Shanghai World Exp...
