Abstract
In the lithium-ion batteries for electric vehicle applications, the battery equalizer is required to enhance life time and guarantee safety. A simple technique that provides effective equalization in terms of battery voltage for a series string of battery cells is presented in this paper. The advantages of accurate equalization are very substantial and include reduced damage to battery cells in the stack and a dramatic increase in battery life. The main circuit technique of two-level DC/DC converters substantially simplifies the structure. Moreover, fuzzy logic equalizing algorithm effectively enhances the uniformity of batteries. The operational principles and design considerations of the proposed equalizer are presented, and equalization performance is verified by the prototype with 6 Ah lithium-ion batteries.
