资料介绍

这里对电动汽车等使用的串联锂电池组存在的多次充放电后不均衡问题。提出一种基于超级电容器和模糊控制的能量转移型均衡电路。该均衡电路从串联电池组中电压高的电池汲取能量,并转移给电压低的电池,从而维护了电池组电压一致性,具有结构简单,控制方便,快速有效的优点。这里对电路工作原理进行分析,介绍了基于模糊逻辑的控制策略,最后用实验结果证明了该均衡电路优良的稳态和动态特性。

A novel equalizer based on super capacitors and fuzzy control is presented, for problem that the EV and HEV used lithium-ion battery series are imbalance when charged and discharged.The equalizer derives energy from the battery with high voltage in the battery strings and transfers energy to the battery with low energy, as to maintain consistency.The circuit has advantage of simple structure, convenient control, quickly and efficiently work.The working principle of the circuit is introduced and fuzzy logic control strategy is analyzed.Excellent steady and dynamic performances of this equalizer are verified by experimental results in the end.
