Abstract: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.
Keywords:microcontroller  photovoltaic battery  charging system  coulometer  state of charge(SOC)
