锂离子电池正成为电动汽车电源的最佳选择。为了防止锂离子电池的充电损伤，延长电池的使用寿命，本文提出并评价了一种基于动态平衡点沿着无耗散均衡器的特殊控制策略。所提出的控制策略的主要焦点是确保电池组的单个电池将快速，有效地，同时通过动态调整均衡电流平衡。在本文中，一个模型的四个串联连接的锂离子电池组已建立评估所提出的控制策略。仿真结果表明了该方法的上级性能。
Li-ion battery is becoming the optimal choice for EV's power supply. In order to keep the Li-ion battery away from charging damage and prolong the battery's life, we present and evaluate here a special control strategy based on dynamic balanced point along with a non-dissipative equalizer. The main focus of the proposed control strategy is to insure that individual cell of a battery pack will be rapidly, efficiently and simultaneously balanced by adjusting equalizing current dynamically. In this paper, a model of four series connected Li-ion batteries pack has been established to evaluate proposed control strategy. The superior performance is shown by the simulation.
