[Application Fields]

· Energy Storage (V2G for Electric Vehicle Energy Storage):
With the increasing number of electric vehicles, it is predicted that by 2030, there will be 80 million electric vehicles globally. Massive amounts of electric vehicles can serve as flexible loads on the user side and distributed power generation devices. V2G enables bidirectional energy flow between electric vehicles and the power grid, allowing electric vehicle owners to charge during off-peak hours and discharge during peak hours to take advantage of price differentials. It enhances load flexibility, reduces distribution network investments, and promotes the integration of clean energy. Moreover, it contributes to the development of the electric vehicle industry and reduces the land occupation of public charging facilities.
