The invention relates to the technical field of electric vehicle wireless charging, and particularly discloses an electric vehicle charging system and method for positioning based on reverse wireless charging, and the system comprises a plurality of electric vehicles, a plurality of parking spaces, receiving coils laid under each parking space, and a plurality of charging piles connected with the plurality of receiving coils in a one-to-one correspondence manner, and the charging pile control system is connected with the plurality of charging piles. Near-field wireless communication is selected as a way for the charging piles to access the Internet, the multiple charging piles are compatible in the same network, when an electric vehicle enters a charging range, the electric vehicle is connected and matched with the vehicle-mounted Internet, a charging pile master control system sends information to the parked vehicle, and then through reverse wireless electric energy transmission, the charging piles are connected with the charging pile. By means of the energy reverse flow capability, current signals are reversely sent to the whole parking charging system, the position information of the parking space where the vehicle is located is determined, other auxiliary positioning devices do not need to be adopted, a large amount of cost can be saved, and positioning is accurate.
本发明涉及电动汽车无线充电技术领域,具体公开了一种基于反向无线充电进行定位的电动汽车充电系统及方法,该系统包括多个电动汽车,多个停车位,铺设于每个停车位下的接收线圈,与多个接收线圈一一对应连接的多个充电桩,以及连接多个充电桩的充电桩控制系统。本发明选择近场无线通信作为充电桩接入互联网的途径,把多个充电桩兼容在同一个网络下,在电动汽车进入充电范围时与车载互联网进行连接匹配,由充电桩总控系统向停入的车辆发出信息,再通过反向无线电能传输,借由能量反向流动的能力,反向给整个停车充电系统发送电流信号,确定车辆所处车位的位置信息,无需采用其他辅助定位装置,可节约大量成本,且定位精准。
