Abstract
An integrated battery case 2 is made by coupling together a plurality of cell cases 3 into an integral body, open ends of the cell cases 3 being closed integrally with a lid member 4. Communicating paths 37 for communicating a suitable number of neighboring cell cases 3 with one another are provided in the lid member 4, whereby the cell cases 3 have a uniform internal pressure.
Claims11
A battery module comprising:
- an integrated battery case that is constituted by coupling together a plurality of cell cases into an integral body, each cell case defining an interior cavity;
- an integral lid member for closing open ends of the plurality of cell cases;
- and
- gaseous communicating paths provided for communicating said interior cavities of neighboring ones of said cell cases with one another.
