The invention relates to a wireless charging dynamic frequency adjusting system and a vehicle, the wireless charging dynamic frequency adjusting system comprises a ground wireless charging module and a vehicle end wireless charging module, the vehicle end wireless charging module is provided with a vehicle coupling circuit, the vehicle coupling circuit comprises a coupling coil and a capacitance adjustable circuit, and the capacitance adjustable circuit comprises a plurality of resonant capacitors. And a controller in the vehicle-end wireless charging module controls a resonant capacitor in the capacitance adjustable circuit to be switched in or switched out so as to realize the adjustment of the working frequency of the coupling coil. And when the working frequency of the coupling coil is inconsistent with the set working frequency, a set number of resonant capacitors are cut in or cut out, then the working frequency of the coupling coil is detected, and if the working frequency of the coupling coil is close to the set working frequency, the capacitance is continuously adjusted in the same capacitance adjusting mode as the last time until the set working frequency is reached. And if the working frequency of the coupling coil is far away from the set working frequency, adjusting the capacitance in a capacitance adjusting mode opposite to the previous capacitance adjusting mode until the set working frequency is reached.

    本发明涉及一种无线充电动态频率调节系统及车辆,包括地面无线充电模块和车辆端无线充电模块,车辆端无线充电模块设置有车辆耦合电路,车辆耦合电路包含耦合线圈和电容可调电路,电容可调电路包含若干个谐振电容,车辆端无线充电模块中的控制器控制电容可调电路中谐振电容切入或切出以实现耦合线圈工作频率的调节。当耦合线圈工作频率与设定工作频率不一致时,切入或切出设定数量的谐振电容,再检测耦合线圈的工作频率,若耦合线圈的工作频率朝向设定工作频率靠近,则继续以和上次相同的调整电容方式调整电容,直到达到设定工作频率。若耦合线圈工作频率远离设定工作频率,则以和上次相反的调整电容方式调整电容,直到达到设定工作频率。
