Immanent problem existed in equalizing charging process may induce performance recession of power battery, and a new method raised in this paper, combining fuzzy strategy, is put forward in dealing with the problem. It is functioned with established mathematical model, closed-loop energy controlled digital pulse-width modulation power source on the foundation of element simulation in Simulink. The method can conduct simulation experiments on system response with and without static load-balance, as well as prompt load-balance respectively. It is shown in the results that, the sever coupling occurred between internal error voltage and external load current, can be escaped by applying the fuzzy controller based on closed- loop energy control model. The results also embrace real-time control output under any error voltage input signal and load current, which improves the adaptability and robustness of the system.
