铅酸蓄电池的并联/串联使用探讨

Discussion on the parallel/series use of lead-acid battery

储能用铅酸蓄电池如何进行串联、并联使用,目前没有相关的规范。有分析认为,只能是同种性质、同种品牌、同种规格、甚至是同批次的蓄电池才能串联、并联使用。这一要求缺乏基本理论依据,也不符合实际应用情况。本文分析了同种性质、不同规格的铅酸蓄电池进行串联、并联使用的可行性和各自的优缺点,并在实际运行中进行了检验。实践结果表明,同种性质不同规格的铅酸蓄电池在采取必要的措施后是可以串联、并联使用的,但要满足蓄电池的使用效能和考虑使用的经济效益,即便同种规格的铅酸蓄电池,也不能直接并联使用。直接并联会存在很大的安全隐患。

How to use lead-acid storage battery for series and parallel,there is no relevant specification at present.Relevant literature analysis thinks,only the same nature,the same brand,the same type,and even the same batch of battery can be used in series and in parallel.This requirement lacks a basic theoretical basis and does not meet the actual application situation.In this paper,the feasibility,advantages and disadvantages of using lead-acid batteries in series and parallel are analyzed and the test is carried out in the actual operation.The practice results show that lead-acid batteries of the same nature and different specifications can be used in series and in parallel after taking necessary measures.However,it is necessary to meet the utilization efficiency and economic benefit of the battery.Even if the same type of lead-acid battery,can not be directly used in parallel.There will be great safety risks in direct parallel connections.
