| 摘 要： | 为了准确了解以蓄电池为动力的电动汽车所用电池的剩余电量，在讨论目前一些电池剩余电量计算方法的基础上，提出了一种基于开路电压法和安时法测量电池剩余电量的新方法。进一步讨论了计算模型的参数自调整和偏差自校正的思想，并在研制的一台剩余电量计上实现了用开路电压法和安时法测量电池的剩余电量。经初步测试，其误差在５％左右。文中详细介绍了这台剩余电量计的情况。

| Abstract: | To know the accurate residual capacity of the EV traction batteries is very important to the drivers of EVs. This paper describes a new algorithm based on OCV AH combination to calculate the residual capacity of lead acid batteries. We have developed a SOC indicator employing this algorithm. The indicator's error is about 5 percent in primary accuracy confirmation test. This paper introduces the indicator in detail. |
