摘要
利用电压/频率变换器配合单片机设计出一种电量计,以实现蓄电池组充.放电电流的数字测量和充、放电电量的准确积算。
In this paper,the author designed a kind of Ampere-hour Meter ,which is based on Voltage/Frequency Convertor and MCS52 MCU,to accurately measure Current and Accumulate the Discharge and Charge Electric Quantity of Storage Battery.Used Electric Quantity Criterion,we can ensure the Accuracy of Discharging Quantity;and compared with the Voltage Criterion in Charging process, we can void insufficient Charge or Over Charge and insure the life of Storage Battery.
