Document Type and Number:
Japanese Patent JP5651444
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a battery module with a long life by dissolving ununiformity of a temperature difference of unit cells in a battery holder with a simple structure.SOLUTION: The module comprises a battery holder 300, which has a plurality of battery housing parts 200, in which unit cells 100 are housed with their polarities aligned in the same direction; and in which the plural battery housing parts 200 are arranged in three or more lines. An area of the battery holder 300 has outer areas S1, S3 having the battery housing parts 100 arranged in the outside line, and a central area S2 having the battery housing parts 100 arranged in the center line. A thermal capacity per cell housing part obtained by diving a thermal capacity of the battery holder in the central area S2 by the number of the battery housing parts 100 arranged in the area is larger than that in the outer areas S1, S3.
