通过电池均衡提高铅酸蓄电池组寿命

探讨了电池均衡对铅酸蓄电池的性能影响。通过以前的研究成果可以看出:有效的均衡过程要求10mV的均衡精度,达到这种精度的电池均衡确实能延长电池组的寿命。主动均衡可以加速均衡过程,而传统的过充电的被动均衡非常缓慢。与其他方法比较,主动均衡很明显地延长了电池寿命。回顾了常用的几种均衡方法并简单介绍了目前的工作。

Life extension through battery equalization of lead-acid batteries

This paper discussed battery behavior and performance related to the equalization problem,in the context of lead-acid batteries.As established in prior work,equalization precision in the order of 10 mV/cell is required for a successful process.Equalization processes that can achieve this precision do indeed extend the life of battery packs.Active equalization speeds the process.Passive equalization(conventional overcharge)is too slow.Active equalization provides clear life extension over the other approaches.Several cell equalization methodologies were reviewed.
