According to the single-pile double-parking-space wireless charging control system and method based on the variable impedance networks, the variable impedance networks are arranged between the inverter and the two wireless energy transmitting modules respectively, and when only one wireless energy transmitting module needs to transmit energy, the wireless energy transmitting modules transmit the energy to the inverter; the equivalent inductance value of the corresponding variable impedance network is adjusted to the minimum set value, and the equivalent inductance value of the other variable impedance network is adjusted to the maximum set value, so that the inverter provides energy for the single wireless energy transmitting module at a preset first power output level; and when the two wireless energy transmitting modules need to transmit energy at the same time, the equivalent inductance values of the two variable impedance networks are adjusted to an intermediate set value, so that the inverter provides energy for the two wireless energy transmitting modules at the same time at a preset second power output level. The beneficial effects are that the circuit structure is simple, the reliability is high, the hardware cost and the installation and maintenance cost are saved, different power distribution can be realized, and different charging requirements are satisfied.

    本发明提供一种基于可变阻抗网络的单桩双车位无线充电控制系统及方法,在逆变器和两个无线能量发射模块之间分别设置有一个可变阻抗网络,当只需要一个无线能量发射模块发出能量时,对应可变阻抗网络的等效电感值调节至最小设定值,另外一个可变阻抗网络的等效电感值调节至最大设定值,使得逆变器以预设的第一功率输出等级为单个无线能量发射模块提供能量;当需要两个无线能量发射模块同时发出能量时,两个可变阻抗网络的等效电感值均调节至中间设定值,使得逆变器以预设的第二功率输出等级为两个无线能量发射模块同时提供能量。其效果是:电路结构简单,可靠性高,节约硬件成本和安装维护成本,能够实现不同的功率分配,满足不同充电需求。
