摘要:

利用库仑计法进行电量监控精度高,因技术要求复杂、成本较高,在电动工具上未能被广泛采用。文中提出了一种2~4串锂电池组库仑计法电量计的设计方案,设计中采用TI公司的MSP 430G2001为主控制器,通过电量计芯片BQ27210对电量信号进行处理。文中介绍了系统硬件设计和软件流程,并对设计中的有关问题进行了说明。该电量计电量指示精确,拥有自我学习能力,成本低、可靠性高、移植性好、扩展性强、具有较强的实用价值。

Abstract:

Coulomb counter is used to monitor the electric quantity.It has high-precision,but the technology is complex and expensive,which confines its application.This paper proposes an implementation of the coulomb counter system based on 2 to 4 cells lithium-powered battery pack.The main controller uses MSP 430G2001,and coulometer chip BQ27210 completes the signal processing of the electric quantity.The designs of hardware and software are given and related issues are introduced.The designed Coulomb Counter System has high-precision,self-learning ability,low cost,high reliability,portability,scalability,practical value and is referential for engineers.

Key words: coulomb counter;battery fuel gauge;Lithium battery;BQ27210
