摘要
为使用户能够了解电池的剩余电量,研究了电池恒流放电规律,设计了剩余电量与总电量百分比测量电路和单片机测量电池剩余电量的测量电路。研究表明,不同的恒流放电电池的剩余电量与总电量比和剩余电压与总电压差之比的关系曲线相同,而且不同型号的电池也相同。通过测量电池的电压值即可获得电池剩余电量与总电量的百分比。而且属于非破坏性实验,测量方法简单。
In order to enable users to understand the battery remaining charge, the battery constant current discharge rule was researched. The measurement circuit of percentage of remaining charge with the total power and measurement circuit of battery remaining power by single-chip were designed. The research shows that for different discharge current value, the ratio curve of percentage of remaining charge with the total power is the same as the ratio of voltage with total voltage difference. And the rule is also same to different types of batteries. The percentage of battery remaining charge with the total electricity power by measuring the battery voltage value could re obtained.This method is non-destructive and simple, and suitable for users,
