Electric Vehicle Charging Fault Monitoring and Warning Method Based on Battery Model

With the development of electric vehicles in China, fault monitoring and warning systems for charging process have received industry’s attention. A method vehicle faults based on a battery model is proposed this paper. Through online estimation state charge power electromotive force, parameters such as charge, voltage, temperature can be adjusted real time to simulate response battery, which batteries different types, specifications, parameters. During process, CAN (Controller Area Network) bus technology used receive analyze information charger, well demand information. The simulated by compared with information, charger determine whether normal. When it judged that occurs, signal sent. This identify more than 10 types faults, including failure BMS (Battery Management System) function. comparison analysis actual accident data verifies feasibility
