The embodiment of the invention provides a battery device, a power utilization device and an energy storage device. The performance of the battery device can be effectively improved. The battery device includes: a first battery cell set including at least one first battery cell; a second battery cell set including at least one second battery cell; the on-off device is used for switching working modes of the first battery monomer set and the second battery monomer set; wherein in the first direction, at least part of the first battery monomers and at least part of the second battery monomers are alternately arranged, the at least one second battery monomer is arranged between the at least one first battery monomer connected with the same confluence component, and / or the at least one second battery monomer is arranged between the at least one second battery monomer connected with the same confluence component. And the at least one first battery monomer is arranged between the at least one second battery monomer connected with the same confluence component.

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.
