The invention provides a wireless mutual charging device for an electric vehicle. The wireless mutual charging device at least comprises a power receiving coil, a power transmitting coil and a position state adjusting device, wherein the power receiving coil and the power transmitting coil are connected with a vehicle-mounted storage battery, and the position state adjusting device is configured to at least keep the power receiving coil and/or the power transmitting coil in different position states. The invention further provides an electric vehicle mutual charging method. The method comprises the steps that the electric quantity margin of the vehicle is determined; determining the power supply and demand state of the vehicle based on the electric quantity margin; and performing mutual charging communication and matching with other vehicles within a predetermined range according to the power supply and demand state, and performing a mutual charging process with the matched counterpart vehicle through the wireless mutual charging device for the electric vehicle according to the present invention. According to the device and the method, wireless charging, especially mutual charging between vehicles, can be realized under various conditions by using configuration as few as possible, so that the problem that the vehicles need to be charged in the driving process or under the condition that no charging pile exists is solved, and the use experience of a vehicle user is improved.

    本发明提出了一种用于电动车辆的无线互充电装置,至少包括与车载蓄电池连接的受电线圈和送电线圈以及被配置成至少能够将受电线圈和/或送电线圈保持在不同的位态的位态调节装置。本发明还提出一种电动车辆互充电方法,其包括:确定本车辆的电量余裕;基于电量余裕确定本车辆的电力供需状态;和根据电力供需状态与预定范围内的其他车辆进行互充电通信和匹配,并通过根据本发明的用于电动车辆的无线互充电装置执行与所匹配的对方车辆之间的互充电过程。利用根据本发明的装置和方法,能够使用尽量少的配置在多种情况下实现无线充电,尤其是车辆间的相互充电,从而解决在行驶过程中或无充电桩的情况下车辆需要充电的问题,提高车辆使用者的使用体验。
