Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1 . A battery pack for a vehicle, comprising: an approximately rectangular pack case; a plurality of flat box-shaped battery modules; a cooling unit; and a junction box for storing a relay, wherein 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. 2 . The battery pack for a vehicle according to claim 1 , wherein the cooling unit includes an evaporator to which a cooling medium is supplied from outside the pack case. 3 . The battery pack for a vehicle according to claim 1 , wherein the cooling unit has a suction port opening toward the adjacent junction box, the suction port being provided at a higher position than an upper surface of the junction box. 4 . The battery pack for a vehicle according to claim 1 , wherein the cooling unit and the junction box are disposed in the vehicle at a front end of the vehicle in a vehicle traveling direction. 5 . The battery pack for a vehicle according to claim 1 , wherein the pack case including the junction box has a reinforcement bar at one end in the longitudinal direction, the reinforcement bar extending in the width direction of the pack case and connecting between a pair of side walls of the pack case, and the reinforcement bar passes above the junction box.
