6、SUN Hang（China Agricultural University, Beijing 100083, China）Abstract：Battery state of charge （SOC） is one of the important parameters in battery management system. Anaccurate estimation for the battery SOC is of great significance. Firstly, the general problems existing in thedefinition of SOC is
7、analyzed, and the fact is discussed that the various conditions of power battery SOC is betterdescribed by the definition with power instead of coulomp. Secondly, the existing estimation methods are divided intofopen-circuit voltage method, ampere-hour integral method, advanced estimation method and
8、 composite method, andtheir advantages, disadvantages and adaptive working conditions are analyzed. Data mining and data fusiontechnology are introduced to the recorded history of battery management system （BMS）data for the SOC estimationto improve the accuracy and scope of application.Key words：bat
