Abstract

With the development and popularization of new energy vehicles, more and more electric vehicles have entered the public's vision, and gradually replaced the traditional fuel vehicles to become a good partner for people to travel. However, electric vehicles have problems such as slow charging process, short driving range, insufficient number of charging piles, and the energy structure of municipal power dominated by thermal power also restricts the emission reduction ability of electric vehicles. The establishment of off-grid optical storage wireless charging system will greatly alleviate this situation. The system uses photovoltaic as a source of all energy, which can be distributed in the open space on both sides of the highway and municipal roads, and the charging base is arranged in the safety zone on both sides of the road or at the traffic light intersection. Its energy storage facilities can ensure the stability of the photovoltaic system power supply and meet the needs of car charging. By optimizing the energy storage battery capacity, photovoltaic panel layout and number, inverter and wireless charging system circuit structure will greatly improve the efficiency and reliability of the charging system, making it possible to use on a large scale.
