摘要
针对离网型光伏发电系统,提出了一种基于PIC单片机的估算蓄电池荷电状态的电量计,分析了估算蓄电池荷电状态常用的开路电压法和安时积分法,并根据安时积分法设计了电量计。
A battery coulometer was presented to estimate the state of charge（SOC） of battery in off-grid PV power system based on PIC microcontroller.PV charge controller chosen a new DC chopper.Furthermore,two commonly used method of estimating SOC were analyzed,the open-circuit-voltage method and the current integration method,and a battery fuel gauge based on current integration method were designed.
