The invention discloses a wireless charging system which comprises a transmitting end and a receiving end, the transmitting end is provided with a transmitting resonant capacitor and a transmitting coil, the receiving end is provided with a receiving resonant capacitor and a receiving coil, the wireless charging system further comprises detection equipment, and the detection equipment is arranged at the transmitting end and/or the receiving end; the detection equipment is provided with a detector and a capacitor access port; when the detection equipment is arranged at the transmitting end, the capacitor access port is connected with the transmitting resonant capacitor and the transmitting coil to form a resonant circuit; when the detection equipment is arranged at the receiving end, the capacitor access port is connected with the receiving resonant capacitor and the receiving coil to form a resonant circuit; and the detector detects a voltage value of the resonant circuit. When the wireless charging system works, the capacitance value of the transmitting resonant capacitor or the receiving end resonant capacitor changes, and the working resonant frequency of the wireless charging system is not changed, so that the resonant circuit is not in a resonant state, the voltage value of the resonant circuit detected by the detector changes, and the influence of the temperature on the system is directly judged through the change of the voltage value.
本发明公开了无线充电系统包括发射端和接收端,发射端具有发射谐振电容和发射线圈,接收端具有接收谐振电容和接收线圈,还包括检测设备,检测设备设置在发射端和/或接收端;检测设备具有检测器,还具有电容接入口;当检测设备设置在发射端时,电容接入口接入发射谐振电容和发射线圈,形成谐振回路;当检测设备设置在接收端时,电容接入口接入接收谐振电容和接收线圈,形成谐振回路;检测器检测谐振回路的电压值。发射谐振电容或者接收端谐振电容的电容值会产生变化,无线充电系统的工作谐振频率不变,这就导致谐振回路不处于谐振状态,从而检测器检测到的谐振回路电压值发生变化,通过该电压值的变化,直接判断温度对系统的影响。
