摘要
针对电动汽车的车载电池续航距离短、充电时间长的现状,设计一套基于电磁耦合谐振的电动汽车动态无线充电系统。该系统分为能量发射部分和能量接收部分,以STM32为控制核心,实现发射端的线圈切换管理及接收端的能量管理功能,具有静止充电、驱动行驶和动态充电三种模式状态。实验结果表明,所设计系统可以根据车载电池电压,自动切换工作模式,采用嵌套方式的接收线圈,在偏移40%情况内,输出功率基本稳定。该设计能够实现电动汽车无线充电的智能化,有助于加快商用化速度。
In allusion to the current situation of short cruising distance and long charging time of on-board batteries of the electric vehicles,a dynamic wireless charging system based on electromagnetic coupling resonance is designed for the electric vehicle. The system is divided into the energy transmitting part and the energy receiving part. In the system,STM32 is taken as the control core to implement the functions of coil switching management at the transmitting end and energy management at the receiving end. The system has three modes:static charging,running charging and dynamic charging. The experimental results show that the designed system can switch working mode according to the on-board battery voltage automatically. The receiving coil with nested mode has basically stable output power within the deviation of 40%. This design can realize the intelligentization of wireless charging of electric vehicle,which is helpful in accelerating the commercial application.
