<p><P>PROBLEM TO BE SOLVED: To uniformly cool a number of unit cells and prevent the degradation of a specific battery caused by temperature unevenness, thereby prolonging a whole life time. <P>SOLUTION: The battery pack for a vehicle includes a battery block 2 to which a plurality of batteries 1 are connected, a cooling passage 3 thermally bonded to the battery block 2 to cool the batteries 1, a cooling mechanism 4 for supplying cooling medium to the cooling passage 3, and an electronic component case 5 for incorporating an electronic circuit connected to the battery block 2. The cooling medium supplied from the cooling mechanism 4 to the cooling passage 3 cools the battery block 2. The battery block 2 cooled by the cooling medium is divided into a supercooled side battery 2A thermally bonded to an outward path side of the cooling passage 3 and a warmed side battery 2B thermally bonded to a return path side of the cooling passage 3. The battery pack arranges the electronic component case 5 in the thermally coupled state with the battery block 2, and the electronic component case 5 is arranged so as to be adjacent to the supercooled side battery 2A than the warmed side battery 2B. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
