The invention discloses an automobile wireless charging control method. The method comprises the steps that (1) when the distance between an electric automobile and a charging pile is within 20 m, a communication relation is established between the electric automobile and the charging pile; (2) the charging pile obtains the position of the vehicle in real time, and when the electric automobile enters the position range with the highest charging power, the charging pile sends a signal that the position of the vehicle is reasonable to the electric automobile; (3) the electric automobile starts to conduct vehicle state self-inspection; (4) if self-inspection is normal, a signal of being ready for charging is sent to devices related to wireless charging in the electric automobile; (5) after preparation is completed, the electric automobile sends a signal of allowing the electric automobile to enter the wireless charging mode to the charging pile; and 6) the charging pile is started to start wireless charging. According to the wireless charging method and system for the electric automobile, the problem of signal interaction between the charging pile and the electric automobile can be solved, the overall structure is simple, the assembling and manufacturing cost is reduced, meanwhile, interaction between the charging pile and the automobile is reduced to the minimum, and the operation reliability of the system can be improved.
本发明揭示了一种汽车无线充电控制方法:1)当电动汽车与充电桩距离20米以内时,电动汽车和充电桩建立通信关系;2)充电桩实时获取车辆位置,当电动汽车进入到充电功率最高的位置范围后,充电桩将“车辆位置合理”信号给电动汽车;3)电动汽车开始进行车辆状态自检;4)若自检正常向电动汽车中与无线充电有关的器件发出“进入充电准备”的信号;5)准备完毕后电动汽车向充电桩发出“允许进入无线充电模式”的信号;6)充电桩启动开始无线充电。本发明电动汽车无线充电方法和系统能够解决充电桩与电动汽车信号交互问题,整体结构简单,降低了装配和制造成本,同时充电桩与汽车交互降到最低,能够增大系统运作的可靠性。
