The invention discloses an automatic switching device for a wireless charging coil of an electric vehicle and a control method. Vehicle parking information is obtained through a wireless sensor arranged on a ground parking space, meanwhile, electric quantity information of a vehicle located on the ground parking space is obtained, and when the wireless sensor detects that the vehicle is parked andthe electric quantity of the vehicle located on the ground parking space is smaller than a charging saturation threshold value, a switching circuit is started to enable a power supply coil to be powered on to work; when the wireless sensor does not detect vehicle parking, the switching circuit is powered off, and a situation that when vehicle parking is not standard, a electric quantity detectionwireless communication module mistakenly recognizes that the obtained vehicle electric quantity is smaller than a set saturation threshold value so that the switching circuit is started to work is prevented; and the working efficiency of the power supply coil is improved, and meanwhile charging safety is increased. The device and the method can prevent a vehicle battery from being repeatedly charged to damage the battery when the vehicle is parked for a long time and a natural discharge point of the vehicle battery is smaller than a set saturation threshold, and guarantee the safety of a vehicle charging process.
本发明公开了一种用于电动汽车无线充电线圈自动开关装置及控制方法,通过设置于地面停车位上的无线传感器获取车辆停放信息,同时获取位于地面停车位上车辆的电量信息,当无线传感器检测到有车辆停放时且位于地面停车位上车辆的电量小于充电饱和阈值,则开启开关电路使供电线圈得电工作;当无线传感器没有检测到车辆停放时,则开关电路断电,防止车辆停放不规范时,电量检测无线通讯模块误识别获取车辆电量小于设定饱和阈值而使开关电路开启工作,提高了供电线圈的工作效率,同时提高充电安全性;本申请能够防止车辆长时间停放,车辆电池自然放点小于设定饱和阈值时,使车辆电池反复充电进而损坏电池,确保了车辆充电过程的安全性。
