摘要：In electric vehicles (EVs), the lithium-ion battery is used as the main energy storage because of its large capacity and high power density. The traditional battery management system (BMS) simply measures battery voltage and current. Most battery damage is caused by failure of the battery's sensor or actuator error detection, which can affect driving safety. Therefore, the system requires accurate failure diagnosis on the battery is significant. An equivalent circuit model should be established precisely to monitor battery charge, open circuit voltage and to diagnose the possible faults at the same time. In this study, equivalent circuit models of LiMn2O4 batteries were implemented in the MATLAB Simulink model to determine the limit of voltage and current as well as the method of failure diagnosis. Simulation results indicate the accurate failure diagnosis of the model.
