| 摘 要： | 根据电池在工作过程中任意时刻的剩余电量理论上应该等于电池的实际容量减去放电电量的原理，推导出了剩余电量的实用计算公式，设计了剩余电量计量系统。通过对一组铅酸电池的实车道路测试，发现其计量误差大约为20％，误差主要由电池的实际放电模式与试验模式的不同所造成。

| Abstract: | According to the residual capacity in any time being the difference of the actual capacity and the quantity of output charges during the discharging of a battery in terms of theory, the paper put forward a formula and a system to compute the residual quantity. Test results show that the system error is about 20% , and the key reason of error comes from the difference between lab discharging mode and practice discharging mode of battery. 2 tabs, 3 figs, 8 refs. |
