摘要
针对目前的笔记本电池多采用保护板来进行保护,而保护板的工作状态又无法得到检测的情况。设计了一个保护板测试仪,该测试仪的核心是充电管理芯片PS501和控制芯片C8051F020。该测试仪系统可以有效的测量笔记本电池保护板通信是否正常,对保护板进行充放电。保证了笔记本的电源管理模块与笔记本电池能够正确通信,防止有害的充电状态,对电池进行保护,增加电池的使用寿命,使其能够可靠的工作。
In view of the present situation that notebook computer battery uses battery protection board to protect widely, and the working status of the protection board can not be detected. This paper designs a protection board tester,the core of the tester is charging management chip PS501 and the control chip C8051F020. The tester system can measure note- book computer battery protection board communication whether normal or not effectively, charge and discharge battery protection board. The tester system can ensure the notebook computer power management module to communicate with the battery correctly,can prevent the harmful state of charge, protect the battery, increase the life of battery, make the battery work reliably.
