STM32处理器的锂电池组保护电路设计

摘要

为实现对电池组的过电压、欠电压、过电流等基本保护和电池组的温度保护,以及电池组单体电池间电压均衡功能,提出了一种针对由4节锂离子电池组成的锂电池组保护电路.该电路以STM32F103处理器和X3100电池保护芯片为核心进行设计,采用C语言编写,使用Keil软件调试.可用于各种使用锂电池供电并且以STM32处理器为核心开发的电子产品.%This paper proposed a lithium battery protection circuit based on the STM32F103 processor and X3100 battery protection IC.The circuit realized the battery overvoltage,undervoltage,overcurrent protection and battery temperature protection,as well as cell voltage balancing function.The results show that the circuit can be applied to all kinds of electronic products which use lithium battery as its power and use the ARM as the core.
