This paper presents a shift gating equalization charging system for power battery pack. Each cell is equipped with a gating charging module in this system. In order to make an equalization charging for power battery pack, battery management system control gating charging module,increasing the charging current of the battery which is charging slowly,accelerating the charging speed. Gating charging module using the shift gating control mode, this control circuit structure is simple and easy to expand. Experiments show that using this system, when charging is completed the battery terminal voltage difference is only 50mV and no overcharging, the power battery pack achieving an equalization charging purposes.
