Abstract：In order to extend the service life of wireless charging in the car battery, improve the charging efficiency and speed, meet the battery charging process of constant current charge first to a certain voltage constant voltage charging, in this paper, starting from the essential attribute of circuit, analyzes the bilateral LCC constant current output and bilateral LCL constant voltage output characteristic, studied the method of constant current constant voltage charging battery, and designs the after switching state, can keep the output current and voltage in same resonant frequency location of the charging circuit.In Simulink, the output current and voltage characteristics were observed, and a set of parameters which could realize the bilateral LCC constant current output and bilateral LCL constant voltage output weregiven. Meanwhile, the transmission power and efficiency of the scheme were studied.
