Combined battery

Abstract

The combined battery of the present invention includes two end plates and a plurality of general cells stacked adjacent each other and bound by two end plates. The general cells are provided with a battery container made of resin, and bound by two end plates with a binding force equal to or lower than a threshold value determined based on the number and the compressibility of the cells and the stiffness of the battery container, in such a manner that no more than a predetermined amount of irreversible deformation will be caused in the battery container.

What is claimed is:  
     
         1 . A combined battery comprising two end plates and a plurality of cells stacked adjacent each other and bound by the two end plates, 
 wherein the cells are provided with a battery container made of resin, and    the plurality of cells are bound by the two end plates with a binding force equal to or lower than a threshold value determined based on a number and a compressibility of the cells and stiffness of the battery container, in such a manner that no more than a predetermined amount of irreversible deformation will be caused in the battery container.    
     
     
         2 . A combined battery according to  claim 1 , wherein the cell includes an electrode plate group containing positive electrode plates and negative electrode plates stacked adjacent each other with separators interposed therebetween, and 
 the cells are stacked in a direction corresponding to a stacking direction of the electrode plate group.
