An energy adjusting device is provided which transfers energy charged in an arbitrary cell to the input/output terminals of a unit energy storage device. The energy adjusting device includes a transformer having a plurality of primary coils and a secondary coil mutually coupled magnetically but electrically insulated, switching circuits which open and close the circuits of the primary coils of the transformer connected to the arbitrary cell, a circuit connecting the secondary coil of the transformer via a rectifying circuit to the input/output terminals of the unit energy storage device, and a control circuit which, by operating the switching circuits, adjusts the amount of energy stored in the cells to a specific ratio with respect to the amount of energy stored by the unit energy storage device.
