Development research about the power battery management system of pure electric vehicle

Battery management system can provide accurate and reliable power battery information to electric vehicle, as well as carry on real-time monitoring to the various functions of battery management system itself operated. And it also can carry on acquisition and analysis to battery running data. The electric vehicle power battery management system designed in this paper has solved the real-time accurate collection problem of battery monomer voltage, which lays a good foundation for accurate judging the battery status and accurate measuring state of charge (SOC).
