| 摘 要： | 由于动力电池的真实荷电状态SOC受许多因素的影响，基于电压检测的电量表很难收到理想的效果。设计了一种基于C8051F330单片机和按时积分算法的电量袁，可以准确计算出蓄电池的残余电量和荷电状态。实验表明：其测量误差小于±5％。

| Abstract: | Since the actual SOC of power batteries is influenced by many factors, it is difficult to obtain ideal results by coulometer based on testing the voltage of batteries. The author designed a coulometer based on C8051F330 MCU and AH integral principle to calculate the residual capacity and SOC of power batteries, it can get the accurate and reliable SOC of battery correctly. The results showed the accuracy is with ±5% by experimentations. |
