The utility model relates to the technical field of power grid energy exchange, more specifically to a bidirectional energy exchange system between electric vehicle and power grid. Background technology: due to the uncertainty of load demand, the voltage and frequency regulation of power grid increases the operation cost of power grid to a large extent. In addition, renewable energy systems are widely connected to the power system, because of its natural discontinuity will also cause fluctuations in power generation. It is urgent to compensate the grid load with battery energy storage system, so as to smooth the natural variability of renewable energy, ensure the stability of grid frequency and restrain the voltage rise caused by reverse power flow. At the same time, with the promotion and application of a large number of new energy electric vehicles, most of the electric vehicles have a stop state for nearly several hours in a day, and their batteries belong to the stop stat...
