基于AVR的笔记本电池检测仪

Surveymeter of Laptop Battery Based On AVR

本文研制了以ATMEGA88为核心、上位机软件为辅助的笔记本智能电池监测仪。监测仪通过系统管理总线将把电池的容量、电压、温度等信息通过RS232发送给上位机软件进行分析,并控制充放电电路对电池进行充放电以检测笔记本电池是否达到设计要求。

This paper studies the intelligent battery tester of laptop computer. This tester takes ATMEGA88 as core and takes PC software as an auxiliary. With the help of the system management bus the tester sends information to the PC for analyzing by RS232 Bus which the data of capacity,voltages,temperature and so on, and control the circuit of charging and discharging for the battery, the purpose of circuit is to detect faults in battery.
