摘要： 以铅酸蓄电池为研究对象，针对蓄电池起火爆炸原因设计基于单片机的充电保护系统。分析铅酸蓄电池充电起火的机理，介绍系统的软硬件组成，对基于Proteus 7 的单片机系统进行仿真。模拟结果表明，基于单片机的充电保护系统可以实现发生两个及以上主要失控现象时的自动断电报警功能。保护系统可对电池充电过程进行火灾预防保护，对电池充电保护装置后续研发提供一定参考。

Abstract: Taking lead-acid battery (VRLA) as the research object,the charging protection system based on single-chip microcomputer was designed for the cause of fire and explosion of the battery. Fire reason of battery during charging was analyzed.The software and hardware were introduced.The single-chip system based on Proteus 7 was simulated. Simulation results showed that, the charging protection system based on singlechip can achieve the automatic power off and alarm function when no less than 2 main runaway happen. The protection system can protect the charging process from the fire, and can provide reference for study on battery charging protection system.

Key words: electric bicycle fire, lead-acid battery, thermal runaway, hydrogen evolution explosion, charging protection device
