The invention relates to an electric vehicle dynamic wireless charging system based on segmented series connection of transmitting coils, a transmitting end comprises a plurality of transmitting coils arranged and distributed along a vehicle driving path, every two transmitting coils form a group to form a transmitting unit, and the two transmitting coils in each transmitting unit are connected in series through a resonant capacitor. Each transmitting unit is connected with a direct-current bus through an inverter box, the receiving end comprises two receiving coils which are arranged front and back along the driving direction of the automobile, the two receiving coils are respectively provided with a secondary side compensation network and a rectifying circuit, and the two rectifying circuits are connected in parallel and output to supply power to a load; each transmitting unit in the transmitting end dynamically switches power supply according to the positions of the two receiving coils in the receiving end, and the two receiving coils do not directly face the two transmitting coils in the same transmitting unit at the same time and are also not in a transition area state at the same time. The beneficial effects of the invention are that the safety performance is improved, the component cost is saved, and the power output is relatively stable.
本申请涉及一种基于发射线圈分段串联的电动汽车动态无线充电系统,发射端包括多个沿汽车行驶路径排列分布的发射线圈,发射线圈两两一组构成一个发射单元,每一个发射单元中的两个发射线圈之间通过谐振电容串联,每一个发射单元通过一个逆变箱连接直流母线,接收端包括沿着汽车行驶方向呈前后布置的两个接收线圈,两个接收线圈分别配置有副边补偿网络和整流电路,且两个整流电路并联输出为负载供电;发射端中的每个发射单元根据接收端中的两个接收线圈的位置动态切换供电,两个接收线圈不同时正对同一个发射单元中的两个发射线圈,且也不同时处于过渡区状态。其效果是:提高了安全性能,节约了元器件成本,功率输出相对平稳。
