1results about How to "Reduce voltage requirements" patented technology

The application relates to a battery equalization method and device, a battery management system, equipment and a storage medium. The device is applied to a battery pack comprising a plurality of battery monomers connected in series, and the device comprises a transformer, an isolation switch and a control unit. The primary winding of the transformer is connected with a total positive electrode and a total negative electrode of the battery pack, the secondary winding of the transformer comprises a plurality of secondary windings, and the plurality of secondary windings are connected with the plurality of battery monomers in the battery pack one by one. The isolation switch assembly corresponds to the plurality of battery monomers in the battery pack one by one, and each isolation switch assembly is connected in series between the corresponding battery monomer and the secondary winding. The control unit is connected with the battery monomer and the isolation switch assembly to detect the voltage signal of each battery monomer and control the isolation switch assembly to be closed according to the voltage signal, so that the transformer balances the energy among the battery monomers in the battery pack. The application solves the problems of high cost, high complexity and slow equalization speed of the battery equalization function of the BMS system.
