资料介绍

在大规模的电池储能应用中,单体电池需要串并联应用,以使电压和容量达到要求,而生产、使用过程中的差异导致电池单体的不一致性是影响储能电站寿命的主要因素之一。储能电池在长期充放电过程中,蓄电池组内各单体电压的离散性会逐渐变大,致使整组电池寿命下降甚至失效,因此普遍采取各种均衡电路降低电池不一致性的影响。本文对几种常用的蓄电池组均衡电路做了简单的比较,包括能量耗散型均衡电路和能量非耗散型均衡电路,着重对开关电容法工作原理及其工作效率进行了分析,得出开关电容法的均衡效率与电池初始状态有关,而与电容容值大小无关等结论。

For the large-scale energy storage applications, the cells need to be in series/parallel to get the required voltage and capacity. The inconsistency of the cells due to the manufacturing process and using is one of the main factors affecting the service life of energy storage unit. In the charging and discharging process of battery for long-term energy storage applications, the difference of the voltage of cells will gradually become larger, leading to the fading of battery or even failure. Various kinds of equalization circuits are applied to reduce the influence of battery inconsistency. In this paper, a comparison of several kinds of commonly used battery equalization circuit, inc...
