-The design parameters of the main circuit and in MATLAB/Simuhnk environment simulation. The paper also proposed to MC9512D64 core bidirectional DC/DC converter control panel and controller hardware and software design. Charging using the combination of constant current charge and constant voltage charge control strategy to achieve the control of cell voltage, and to improve the charge-discharge control performance and security. The charging and discharging system prototype test results show that: when fully loaded, the system efficiency is above 80 , more than 99　of the power factor, harmonic content below 5 , to meet the design requirements, verify the feasibility of the design of the system.
