This paper has applied battery pack technologies in battery system based on the characteristics of charging and discharging process and composed big battery pack from single battery cells with MSP430 as micro control unit (MCU). The paper has also designed the monitoring hardware system of main control unit, data monitoring module, as well as the monitoring software of upper computer of CAN communication technologies with collected voltage, current and temperature of battery. The upper software is designed by module process with real-time monitoring function in voltage and temperature. SOC on-line prediction can be obtained by the establishment of mathematical model of Li-ion battery based on Extended Kalman Filter algorithm (EKF), the accuracy of the prediction is about 2.7%. The algorithm can be applied in battery management system of Li-ion battery for electrical vehicles with the same application effect and accuracy.
