For the imbalance phenomenon of battery packs in electric vehicles, a new charge equalization converter using flyback DC/DC in electric vehicle battery system was designed, The principal and circuit of the equalization system were particularly presented, as well as three balancing strategies name Top , Bottom and mixture balancing . The method of modeling for flyback DC/DC and Li-ion battery was described, and the PSIM simulation model of the equalization system was built. The mixed strategy was simulated under 5 kHz high frequency condition , and the SOC of experimental batteries were involved from 44.3% to 55.7%. For all the errors between simulation and experiment results were within 10%, the simulation circuit and modeling methods were verified as well as the correctness of the hybrid control strategy.
