Title:
BATTERY ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/1998/040918
Kind Code:
A1
Abstract:
A battery assembly usually provided with a plurality of battery modules (16). At the time of manufacturing the assembly, the battery modules (16) are incorporated in a battery case (10) having fixed bulk heads (14) and intermediate bulk heads (20) so that they pass through battery holding holes (18) and battery inserting holes (22). The connecting sections of the batteries (12) constituting each module (16) are held and supported by the battery holding holes (18) of the fixed bulk heads (14). The batteries (12) are efficiently cooled or warmed regardless of the vertical position of the batteries (12) by blocking the flow of a cooling/warming medium which flows upward from the bottom side with tuning projections (38) or adjusting the cross-sectional area of the flow passage of the medium. Since the intermediate bulk heads (20) are separately formed, this battery assembly can be manufactured and assembled easily. In addition, the batteries (12) can be cooled or warmed efficiently with fewer parts and assembling man-hours. This battery assembly can be suitably mounted on a motor-driven vehicle, such as the electric automobile, etc.
