<p><P>PROBLEM TO BE SOLVED: To provide a battery structure for effectively cooling. <P>SOLUTION: In the battery structure arranged in a common battery housing and having at least two battery cell packs, the battery cell packs are mutually and vertically arranged in the battery structure wherein the battery housing includes at least one first opening for supplying cooled air and at least one second opening for discharging heated air, and partitions a tunnel formed between the battery cell packs in a height direction. Here, at least a first opening is substantially arranged at the same height with the tunnel, and the tunnel is closed at a side facing to the second opening. Thus, air passing the first opening flows in the tunnel, and comes out through the second opening by passing or making a detour of the battery cell pack. Alternatively, at least the second opening is substantially arranged at the same height with the tunnel, and the tunnel is closed at a side facing to the first opening. Thus, a flow of the cooled air is reversed. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
