Abstract:Lithium-ion battery is used as the main energy storage in electric vehicles (EV) because of its large capacity and high power density. The battery management system (BMS) of EVs is important. The traditional BMS simply measures battery voltage and current. Most battery damages are caused by failure of error detection by the sensors or actuators of the battery. Therefore, the system requires accurate fault detection on the battery. An equivalent circuit model should be established precisely to monitor battery charge and open circuit voltage. In this study, equivalent circuit models of LiMn2O4 batteries were implemented in the MATLAB Simulink model to determine voltage and current limit. Simulation results indicate the accurate fault detection of the model.
