Title:
BATTERY STACK AND BATTERY MODULE USING THE BATTERY STACK
Document Type and Number:
Japanese Patent JP2021093331
Kind Code:
A
Abstract:
To obtain a battery stack and a battery module, capable of improving radiation performance of a plurality of battery cells on which water proof measures are taken, with simple structures.SOLUTION: A battery stack 12 has an opening 40 on a resin frame 18 provided between battery cells 16 arranged so as to be adjacent to each other. The opening 40 is formed between tips of a support part 26 and a support part 28 that are formed by being bent from bottom edges of side wall parts 22, 24 of the resin frame 18 in directions in which the support parts become closer to each other. Thereby, at an undersurface 38 of a battery cell 16, a region other than both end parts 30, 34 of the battery cell 16 is exposed through the opening 40. Because a plurality of battery cells 16 are arranged along the longer direction of the battery stack 12, a large opening 41 is formed by continuous openings 40. Cooling the battery cells 16 through the large opening 41 makes it possible to improve radiation performance of the battery cells 16 with a simple structure.SELECTED DRAWING: Figure 2
