Abstract: This paper designs a battery detection system of electric vehicle with STM32 as the core. The SOC value is
estimated by ampere-hour integral method, and the charging and discharging voltage of each battery in the balanced control
circuit tends to be consistent. The test and experiment results show that the voltage balance between each cell effectively
improves the service efficiency and life of the cell.
Keywords: Storage battery; SOC estimate; Equalizing control
