Abstract—To realize electric bus's quick charge, which choose nickel metal hydride (Ni-MH) capacitor battery as its power system in Zibo, then analysis and design quick charge system. Using the Matlab/Simulink measures the power grid harmonic content, and according to the Ni-MH capacitor battery's short-time large current charge characteristics, selecting voltage controller method as charging terminate parameters. Eventually, realize the electric bus's quick charge through the field experiment. At the same time, in the use of the Ni-MH capacitance power battery, the performance difference of battery cells makes the voltage unbalance in the charge and discharge processes, which traditional balanced method also needs long time. This paper studies the quick charge method of the power battery, and proposed a sawtooth balance strategy which can increase the battery life. Based on the proposed charge control strategy, and test on Zibo electric bus for balance charging. Experimental results show its feasibility and effectiveness.
