Study on the application of lead-acid batteries in micro-grid energy storage system

铅酸蓄电池具有成本低、可靠性好、性价比高等优点,因此成为微网中常见的储能形式。然而,寿命短、能量转换效率低、废弃电池污染环境等弱点使得铅酸蓄电池在储能系统中的应用还需要进一步完善。延长电池的工作寿命、提高蓄电池的充电效率,研究一种带修复功能的蓄电池智能管理系统,是微网储能中十分令人关心的问题。本文中,简要介绍了蓄电池智能管理系统,用谐振脉冲修复技术对微网储能系统中的铅酸蓄电池进行修复的基本原理,以及算例分析,并简单评估此系统的实际效用。

The lead-acid battery has the advantages of low cost,good reliability,cost-effectiveness,therefore,lead-acid battery becomes a common form of energy storage in micro-grid.However,due to the short service lifetime,low energy conversion efficiency,waste batteries polluting the environment and other weaknesses,the application of lead-acid batteries in energy storage system needs a further improvement.In order to prolong the working life of the battery and improve the charging efficiency of the battery,the research of an intelligent battery management system with repair function is a very concerned problem in the energy storage of micro-grid.This paper briefly introduces an intelligent battery management system,according to the micro-grid energy storage system,the basic repair principle of lead-acid battery by using resonance pulse repair technique,the case analysis,and a brief evaluation of actual utility of this system.
