电池/超级电容器(SC)混合储能系统因其具有高功率密度、高循环能力、长寿命等优点而受到广泛的研究。通过无线电能传输(WPT)对HESS进行重复充电是一种潜在的减小车载电池尺寸的解决方案。对于WPT充电，提出了利用DC-DC转换器进行负载阻抗控制，以提高传输效率。由于HESS的容量有限，充电功率控制也是必要的。此外，还应在接收端进行功率控制，以简化传输端的配置。本文提出了一种基于小波变换的充电功率控制方法，发射端和接收端之间不需要通信。通过实验验证了前馈控制方法的有效性。
Battery/Supercapacitor (SC) hybrid energy storage system (HESS) is widely researched due to the superiority of SC in high power density, high cycle capability, and long life time. The repetitive charge for HESS via Wireless Power Transfer (WPT) is a potential solution for reduction of battery size on board. For WPT charging, the load impedance control using DC-DC converter was proposed to improve the transmission efficiency. The charge power control is also necessary because of the limited capacity of HESS. Moreover, the power control should be done on the receiver side to simplify the configuration of transmission side. In this paper, charge power control via WPT without communication between transmitter and receiver side is proposed. The proposed method applied the feedforward controller is verified by experiments.
