动力电池电量计

Power Battery Coulometer

分析了各种电池荷电状态估算方法的优缺点,提出了一种实时检测电池端电压作为判断电池充电状态的安时计量算法。由于该算法构成的电量计能实时、准确计算电池的电量和SOC,并应用于风光互补路灯系统,保证了路灯照明安全、可靠地运行。

To establish the need for battery management system,to explore battery state of charge（SOC） of the real-time measurement and estimation methods,the advantages and disadvantages of the various battery SOC estimation method were analyzed,a real-time detection battery terminal voltage as the battery charge status to determine the voltage-Ah counting algorithm was proposed.The power battery coulometer,which was made of the algorithm,could calculate real-time,accurately the battery＇s SOC,successfully apply to wind and solar street lighting system,and ensure street lighting safe and reliable operation.
