The invention discloses a battery management system supporting active equalization, and relates to the technical field of battery detection.When the system runs, a battery state monitoring module monitors and integrates working state data of battery units in real time, generates a battery state vector BSV, recognizes a current charging mode CM of a battery pack, and stores the battery state vector BSV; by adjusting the equalization strategy ASOC between the battery units in real time, the charging fluctuation range between the battery units is effectively limited, and the phenomena of loss and overheating caused by uneven current or charging speed difference in the charging process of the battery units are avoided. By monitoring the working state of the battery unit and comparing the working state with the safety working early-warning threshold value Ath, the overheating or overload risk of the battery unit can be recognized in time, and possible safety accidents are avoided. By summarizing and calculating the overall charging efficiency OE of the battery pack, a targeted charging optimization scheme can be provided, the charging efficiency is further improved, and the energy loss is reduced.
