<p><P>PROBLEM TO BE SOLVED: To provide a high-strength battery module capable of restraining temperature rise even when large-current charge and discharge are executed. <P>SOLUTION: This module 60 is composed by composing each battery pack by arranging four cells each having a cell lid and a cell can providing electrodes different from each other in a line so that the bottom surfaces of the cell lids and the cell cans are alternately arranged in the side surface direction, composing each submodule 40 by fixing the battery pack by a frame body comprising a battery pack holder and a battery pack cover, and electrically connecting the cells, housing and arranging 14 pieces of the submodules 40 in an armoring case of a hexahedron comprising a lower case 45, an upper case 47, side cases 49, 50 and 51 and electrically connecting them. On the lower case 45 constituting one surface of the armoring case, a honeycomb structure is arranged. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
