The invention provides a wireless fast charging system and method for an electric vehicle. The wireless fast charging system comprises a battery pack, a wireless charging receiving module, at least one wireless charging transmitting module, a battery management controller and a charging management module. The charging management module controls the working state of the wireless charging transmitting module; the wireless charging transmitting module is used for transmitting electric energy in an external power supply to the wireless charging receiving module; the wireless charging receiving module receives the electric energy transmitted by the wireless charging transmitting module and transmits the electric energy to the battery pack, and the battery pack supplies power to the electric vehicle; the battery management controller is connected with the battery pack, is used for calculating the SOC of the battery pack, and is in wireless communication connection with the charging management module; and the battery management controller or the charging management module controls the number of the wireless charging transmitting modules needing to work. According to the technical scheme, the state of the battery pack is fed back to the charging pile in real time through wireless communication, the output power is controlled, the charging efficiency is improved, resource waste is prevented, and an efficient and convenient wireless charging mode is achieved.

    本发明提供了一种电动汽车无线快充系统及方法,包括电池包、无线充电接收模块、至少一个无线充电发射模块、电池管理控制器及充电管理模块;充电管理模块控制无线充电发射模块的工作状态;无线充电发射模块用于传输外部电源中的电能至无线充电接收模块;无线充电接收模块接收无线充电发射模块传输的电能并将电能传输至电池包,电池包给电动汽车供电;电池管理控制器与电池包连接,用于计算电池包的SOC,并与充电管理模块无线通信连接;电池管理控制器或充电管理模块控制需工作的无线充电发射模块的数量。通过此技术方案,采用无线通信实时将电池包的状态反馈至充电桩,控制输出功率,既提高充电效率,又防止资源浪费,实现高效便捷的无线充电方式。
