At present, V2G(vehicle to grid) technique is received more and more attention due to developing of renewable energy sources. So, development process of EV(electric vehicle) technology is introduced in this paper and relative difficulties in V2G is analyzed. The main difficulties including the service life of battery, control strategy of current and the EVs paralleling into the grid. Battery charger is one of the key technologies of V2G.The charger consist of a filter, an AC/DC converter for grid interface and multiple bidirectional DC/DC converters for EV battery management, and a direct-current control mechanism is employed for ac system bus voltage and dc-link voltage control. Simulation results show that the AC/DC converter and the DC/DC converters have the function of electric power flowing with two-ways. Finally it points out the development direction of V2G technology.
