Abstract
The present invention provides a modular system for accommodating batteries therein, which has a simple structure and a high reliability and prevents a difference in properties between the batteries included therein. The modular system includes a plurality of single batteries,, which are arranged side by side between the beams of a top plate,and a bottom plate,to locate covers of the batteries,with terminals on a front side of the top plate,and the bottom plate,. The single battery,has a plurality of ribs,that are formed on a specific pair of opposite outer surfaces in such a manner as to extend in a longitudinal direction of the single battery,, and have concaves formed at regular intervals. The plurality of ribs,formed on each outer surface of each single battery,are in contact and joined with the plurality of ribs,formed on a matching outer surface of an adjoining single battery,. The joint surfaces of the adjacent single batteries,form connection grooves,that are defined by the concaves of the ribs,and extend perpendicularly to the top plate,and the bottom plate
