That is, the unit batteries 20 shown in FIGS. 1 and 2, FIGS. 3 and 4, FIGS. 7 and 8, and FIGS. 11 and 12 can be fixed to each other in a state of being arranged in both the vertical direction and the horizontal direction. With this configuration, the number of unit batteries 20 can be easily changed according to the required amount of power. In FIGS. 1 and 2 and FIGS. 3 and 4, the first connecting hole 241 is used when connecting vertically, and the second connecting hole 242 is used when connecting horizontally. Used. 7 and 8, when the unit batteries 20 are connected in the horizontal direction, the upper and lower opposing surfaces of the unit case 22 are made to project from the terminal projecting surface 20a to form a “lid attaching portion”. What is necessary is just to provide a through-hole etc. in a cover attachment part, and connect the through-holes arranged in the horizontal direction with a bolt etc. In FIGS. 11 and 12, when the unit batteries 20 are connected in the horizontal direction, when a bolt or the like is screwed into the mounting female screw portion 26 through the mounting hole 331, the unit cells adjacent in the horizontal direction are connected. What is necessary is just to connect with a battery via the attachment hole part 331.

  Further, in the above embodiment, as described above, the connecting portion 24 is provided on the unit battery 20, and the plurality of unit batteries 20 are connected to each other and fixed using the connecting portion 24. This fixing step is performed in a relatively large space in front of and behind the unit battery 20, as shown in FIGS. Therefore, according to the configuration having such a connecting portion 24, the fixing step for fixing the plurality of unit batteries 20 can be performed easily in a short time.

  The present invention is not limited to the above embodiments, and various changes other than those described above can be made without departing from the gist of the present invention.

  For example, in each of the embodiments described above, the case where the unit battery is configured using eight storage batteries has been described. However, the present invention is not limited to this configuration.If necessary, seven or less or nine or more. A unit battery may be configured using a storage battery.

  Also, in the above-described embodiments of FIGS. 1 and 3 and FIGS. 11 and 13, the case where the lid is formed by bending a plate-like member such as a steel plate is described, but the present invention is not limited to this configuration. The lid may be formed by welding a plurality of members as long as a predetermined interval can be provided between the lid and the terminal protruding surface of the unit battery.
