Abstract Hybrid energy storage system (HESS) has dual advantages of high power density and high energy density, but it is rarely discussed for wireless power transfer (WPT) system. Considering the characteristics of WPT system, this paper optimized the power allocation strategy of HESS. First, the circuit of the WPT system charging for HESS is proposed, the circuit adopts a primary-side inductor/capacitor/capacitor compensation and secondary-side series compensation topology. The compensation topology has a constant voltage output of the secondary side, the equivalent load of the coupling coils can be controlled to the optimal value if the input power of HESS is adjusted properly, thus the system optimal efficiency is maintained. At the same time, the wireless charging strategy of HESS is designed according to the power allocation mode of HESS. This control strategy can not only meet the requirements of the system energy output, but also maintain high efficiency of the system. Finally, the feasibility of the control method is verified by experiments.

Key words： Wireless power transfer hybrid energy storage system optimization control power allocation efficiency optimization
