Title:
BATTERY
Document Type and Number:
WIPO Patent Application WO/1999/060653
Kind Code:
A1
Abstract:
A multistage battery having a plurality of battery modules (1) arranged at predetermined intervals in a case (2) includes an obstacle (5), such as a dummy battery, at the upstream end of an air stream flowing along the array of the battery modules so that turbulent flow may occur. The turbulent flow introduced into the case increases heat transmission from the battery modules in upstream regions. Moreover, the heat transmission in the middle of the air stream is also increased by providing a supplementary entrance (7) through which refrigerant is introduced. As a result, the temperature difference between battery modules arranged in the case is reduced, and this simple structure provides a battery of improved quality and stability.
