Analysis on V2G Mode Charging and Discharging Circuit Based on Power Exchange Station

With the development of new energy industry, the number of electric vehicles is also climbing gradually, which promotes the steady development of V2G technology. Based on this status quo, this paper discusses the Vehicle-to-Grid (V2G) mode and its significance, especially the positive significance for the grid side, and details the specific working mode of the V2G mode. Based on the context of a power exchange station, this paper describes the charging and discharging circuit of V2G technology and its working principle, and uses MATLAB/Simulink to build a typical three-phase rectifier and active inverter circuit and observe and analyze its waveform. In the battery swap station, it can not only avoid the adverse impact on the power grid due to the large number of electric vehicles connected to the grid in an uncontrolled manner, but also enable vehicle owners to have a simpler and more convenient experience of changing batteries, which is a major trend for future development.
