In order to ensure good performance and extend the lifetime of li-ion batteries in electric cars, effective real-time monitoring and management must be valued. This paper designs an electric vehicle battery management system based on a smart battery monitoring chip, DS2438. It integrates the measurement of battery's temperature, voltage, current, and power as a whole, which not only simplifies the circuit, but also saves system cost. The battery’s SOC (State Of Charge) can be easily estimated and displayed in this design. It improves the reliability of power battery pack and prolonged its life, which can be used as reference to battery management system design and application.

Share Information

According to the requirements of the battery pack on pure electric vehicles, designed a distributed battery management system using the bus communication technology, the system can detect various operating parameters of the battery in real-time, diagnose and alarm according to the battery status. The system can also share information with the other systems of the vehicle through CAN bus. Through testing the system, the result shows that it can accurately measure the current and voltage of the battery, and the measurement accuracy meets the actual requirements.
