Problems solved by technology
[0007] However, in this case, in order to easily insert the battery block into each layer, it is necessary to provide margins in the height direction and width direction of each layer, and as a result, there is a problem that the power source case becomes thicker.
Generally, for the purpose of arranging as many battery blocks as possible in a limited space, it is not desirable to increase the size of the power supply case.

The invention provides a power source apparatus, a vehicle equipped with the power source apparatus and a power storage system equipped with the power source apparatus. The power source apparatus is made up of an arrangement of a plurality of battery blocks (10) having a plurality of rectangular battery cells with endplates (7) disposed at the ends. A base-panel (41) that carries battery blocks disposed in a horizontal plane, and floor-panels (40) disposed on top of battery blocks and configured with upper surfaces capable of carrying other battery blocks are provided. Battery block endplates (7) have upper attachment sections (52) to attach a floor-panel (40) disposed on the upper surfaces of the endplates (7), and lower attachment sections (54) to attach a base-panel (41) or floor-panel (40) disposed at the lower surfaces of the endplates (7).
Description
Technical field [0001] The present invention relates to a power supply device in which a plurality of rectangular single cells are stacked, a vehicle having the power supply device, and a power storage device, and more particularly to a structure for disposing a power supply device that is mounted on a hybrid vehicle or a fuel cell vehicle , Electric vehicles, electric motorcycles and other electric vehicles to drive the electric motor power supply devices, or power supply devices used in households, factories and other high-current power supplies for power storage. Background technique [0002] Power supply devices with multiple single cells are used in power supply devices for vehicles such as hybrid vehicles and electric vehicles. Such a power supply device is composed of a battery block in which a plurality of single cells are stacked. In particular, with the recent demand for higher output, a structure in which a plurality of battery blocks are combined and arranged has bee...
