舰船混合储能动力系统包括数万个单体电池。每个单电池的性能不可能完全一致。反复充放电后，微小的差异会逐渐增大，这可能导致电池性能和循环寿命急剧下降。针对船用混合储能系统中各单体电池间的不平衡性能，提出了一种融合模糊PID充电均衡器、顺序放电均衡器和浮充均衡器的多模式均衡控制方法，以减小电池组间的差异。根据所提出的平衡控制策略，对由铅酸蓄电池组成的混合储能电池组进行了实验，取得了较好的平衡效果。
Shipboard hybrid energy storage power system includes tens of thousands of single batteries. The performance of each single cell can't be completely consistent. Small differences will gradually increase after repeated charging and discharging, which may lead to a sharp decline of the performance and the cycle life of the battery. For imbalance performance between each single cell of shipboard hybrid energy storage, this paper proposes a multi-mode balance control method, which integrates fuzzy PID charging equalizer, sequential discharging equalizer and floating charging equalizer, in order to reduce the differences between the battery packs. According to the proposed balance control strategy, this paper takes an experiment on the battery packs for hybrid energy storage which are composed of lead-acid batteries, and achieves a better balance result.
