Abstract
The present invention provides an assembled battery with reduced weight and high reliability that can achieve improvement of assembling easiness at low cost. An assembled battery is provided with a frame holding a plurality of unit cellshaving positive polarity at one end and negative polarity at the other end. The frame is composed of two outer frameshaving the same shape and an inner frame. The unit cellsconstituting an assembled batteryare disposed on both sides of the inner frame, and one outer frameand the other outer frameare disposed such that the unit cells are sandwiched between the former outer frameand the inner frameand between the latter outer frameand the inner frame. The two outer framesare joined to the inner framethrough side face coupling portionsand vertical coupling portions. The inner frameis fixed with positive electrode bus bars, negative electrode bus bars, and inter-unit cell bus barsfor electrically connecting the unit cellsin series, and lead wires for voltage detection with a connectorfor detecting voltages of the unit cells
