摘要
Abstract
It is well known that the open circuit voltage and SOC of battery exist close relationship.However,a large number of studies have shown that when the battery charges and discharges at constant current,the changing rule of the terminal voltage and SOC approximates the changing rule of open circuit voltage and SOC.But for the car battery,no literature clearly gives the corresponding relationship expression of voltage and SOC when charging and discharging current change.Through electricvehicle battery charging and discharging experiments,Matlab was used to process experimental data by curve fitting,getting the mathematical relationship of the battery SOC and voltage under changing current,putting forward the modified empirical formula,providing a new way for accurate estimation of battery driving mileage.关键词
