Abstract:
The invention relates to the technical field of cell balancing system, in particular to a balanced battery pack system based on two-way energy transfer, which comprises battery modules, battery management units, a BMS (Battery Management System) master-control unit and a high-voltage two-way DC/DC circuit module, wherein the battery modules are connected with an internal power bus and an internal CAN (Controller Area Network) bus through the battery management units. The balanced battery pack system based on two-way energy transfer utilizes the high-voltage two-way DC/DC circuit module and the public internal power bus and performs centralized control on the number of balanced channels in the whole battery pack through the BSM master-control unit to realize energy transfer, thus achieving the balancing between various single cells in the whole battery pack and between the battery modules.
