Zusammenfassung:	There is provided an assembled battery allowed to compute and detect an SOC easily with high accuracy while increasing energy density. An assembled battery 1 is configured by connecting batteries BT1 to BTn-1 and a battery BTn in series. A discharge curve of each of the batteries BT1 to BTn-1 exhibits substantially flat characteristics, and a discharge curve of the battery BTn exhibits slope characteristics. The SOC or DOD of the assembled battery 1 is detected from the battery voltage of the battery BTn by a battery control unit 3. As the discharge curve of the battery BTn exhibits slope characteristics, the battery voltage is allowed to be detected easily with high accuracy. As the batteries BT1 to BTn-1 have high energy density, the energy density of the whole assembled battery 1 is allowed to be increased, and the size and weight of the assembled battery 1 are allowed to be reduced.
