Battery equalization device, battery equalization control method, battery management system and medium

The invention provides a battery equalization device, a battery equalization control method, a battery management system and a medium. The device comprises a battery management system, a battery pack, a switching network and a power supply, the battery management system is respectively connected with the battery pack, the switching network and the power supply which are connected in sequence; the battery management system is used for detecting a first working parameter of each battery cell in real time and calculating a first charge state of each battery cell, and if the first working parameter and/or the first charge state do/does not meet a corresponding index threshold value, the switch corresponding to the corresponding target battery cell is controlled to be switched from a conduction state to a cut-off state. Through the implementation of the scheme of the invention, under the control of the battery management system, the balanced charging and discharging of the battery can be realized only by adopting
