摘要
相比有线充电系统,电动汽车的无线充电系统具有安全性高、便捷性好等优点。在实际应用中,充电系统的发射线圈和接收线圈难免会发生偏移,从而影响汽车蓄电池的正常充电。另外,高温超导因其高载流密度和低损耗的特点被引入无线充电系统中。基于此,通过采用高温超导线圈取代传统无线充电中的发射线圈,搭建无线充电系统,实验研究了发射、接收线圈偏移对负载电压的影响。通过理论计算和实验结果的对比,验证了互感模型理论同样适合超导无线充电系统,为进一步的研究提供了分析参考依据。
Compared with the wired charging system, the wireless charging system of the electric vehicle has the advantages of high security and convenience. In practical application, the transmission coil and receiving coil of the charging system will in- evitably shift, which affects the normal charging of the car battery. In addition, the high temperature superconductor is introduced into the wireless charging system because of its zero resistance and low loss to study the feasibility of the superconducting wireless charging technology. Based on this, the high temperature superconducting coil was used to replace the transmitting coil of the tra- ditional wireless charging technology, and the wireless charging system was built. The influence of the transmitting and receiving coil offset on the load voltage was experimentally studied. In addition, the comparison between theory and experiment verifies the correctness of the mutual inductance model and provides an analytical reference for further research.
