Battery module

摘要

A battery module with a plurality of battery cells arranged in a first direction in a battery array, the battery module including a plurality of barriers in which a pair of adjoining ones of the barriers mount a battery cell therebetween, a frame having at least a pair of opposed frame members, the battery array and the barriers being between the opposed frame members and disposed internally thereof, the frame including a pair of end blocks at outermost sides of the battery array, side frames connecting the end blocks, and a degassing portion overlying vent portions of each of the plurality of battery cells and providing a passage for directing vented gas from the battery cells away from the battery module, the degassing portion rigidly supporting the battery cells and barriers of the battery array within the frame.

1. A battery module with a plurality of battery cells arranged in a first direction in a battery array, the battery module comprising:
a plurality of barriers in which a pair of adjoining ones of the barriers mount a battery cell therebetween, a frame having at least a pair of opposed frame members, the battery array and the barriers being between the opposed frame members and disposed internally thereof, the frame including: a pair of end blocks at outermost sides of the battery array, side frames connecting the end blocks, a degassing portion overlying vent portions of each of the plurality of battery cells and providing a passage for directing vented gas from the battery cells away from the battery module, the degassing portion rigidly supporting the battery cells and barriers of the battery array within the frame; and a reinforcing barrier in between adjacent battery cells in a central region of the battery array, wherein: the degassing portion continuously extends from one end of the battery array to another end of the battery array and across the central region of the battery array, the reinforcing barrier includes a fastening portion for fastening the degassing portion to the reinforcing barrier, and the reinforcing barrier includes:
a partition wall completely separating two adjacent battery cells,a side surface extending perpendicularly from a plane of the partition wall to cover at least a portion of a sidewall of the two adjacent battery cells, anda mounting portion underlying a side of one of the two adjacent battery cells, the side being opposite to a side that includes the vent portion therein.
