Abstract: The problems during the charging process of electric vehicle battery group and fast charging characteristics were analyzed. On the basis of domestic and overseas developing status of battery management system, a kind of battery management system based on the conception of charging single cell in the same time was proposed. Taking the AT89C51 as the core of control module, collecting voltage, temperature parameter by the V/F conversion machine—LM331 and DS18B20 respectively, and carrying on voltage with the compensation of temperature, the voltage control was achieved and the precision of control was gotten in the charging process.
