Abstract

Provided is a battery pack for a vehicle including an approximately rectangular pack case, a plurality of flat box-shaped battery modules, a cooling unit, and a junction box for storing a relay, in which: the plurality of battery modules is piled up flat in the pack case so that a terminal provided on a short side of each battery module is directed in a longitudinal direction of the pack case; the cooling unit is disposed at one end of the pack case in the longitudinal direction and configured to send and circulate cooling air in the pack case along an outer periphery of the pack case; and the junction box is disposed in a most downstream side of the circulating cooling air beside the cooling unit in a width direction of the pack case.

Description

[0001] Cross References to Related Applications [0002] This application claims the priority of Japanese Patent Application No. 2015-103337 submitted to the Japan Patent Office on May 21, 2015, and therefore the entire content of said Japanese Patent Application is incorporated herein by reference. technical field [0003] The present invention relates to a battery pack for vehicles. Background technique [0004] A large-capacity secondary battery is required to drive the vehicle. Therefore, as a vehicle battery pack, as shown in Japanese Patent Laid-Open Publication No. 2013-171662 and Japanese Patent Laid-Open Publication No. 2015-26428, it is known that a plurality of flat box-shaped battery modules are housed. A battery pack formed inside a battery case. [0005] Here, in Japanese Patent Laid-Open Publication No. 2013-171662, a part of the battery modules are laid flat (a form in which the main surface of the battery module is substantially parallel to the bottom surf...
