摘要
为了测量采用锂离子动力电池组的电动汽车的剩余电量并估计其续驶里程,设计了一套电池SOC(荷电状态)的车载测量系统。该测量系统基于开路电压法与安时计量法,实现了电压、电流的实时采集,根据测量出的SOC可换算成剩余续驶里程并在液晶仪表上实时显示。车载试验表明,相比其他电量计量系统,该系统实用可靠。
In order to measure power consumption and estimate the continued drive mileage of electric vehicle batteries with lithium-ion power, a new set of vehicle battery＇s state of charge measurement system is designed. The system can collect real-time voltage and current exactly by using the open circuit voltage and Ah counting measurement method. The measured state of charge can be converted to the remaining continued drive mileage, which can be displayed on an LCD instrument. Experimantat results show that this system is practical and reliable. Its performance is much better than other electricity metering systems.
