Power source device and battery cooling structure for vehicle
First Claim
1. A power source device for a vehicle having left and right side frames extending longitudinally with respect thereto, said power source device, comprising:
- a battery box, housing one or more battery modules, and being mounted on a vehicle body, said one or more battery modules supplying electric power to a motor for driving the vehicle, wherein the battery box is mounted between the left and right side frames such that said one or more battery modules are offset altogether to one of a left and right side of the vehicle, with respect to a center line thereof, such that a majority of said battery or battery modules are located on said left or right side of the vehicle with respect to the center line;
an intake duct connected to the battery box at an other of the left and right sides of the vehicle, for supplying cooling air to said one or more battery modules; and
an exhaust duct connected to the battery box at said other of the left and right sides of the vehicle, for exhausting cooling air from said one or more battery modules.

Abstract
A battery box housing a battery is mounted between left and right side frames extending in a longitudinal direction of a vehicle body so that the battery box is offset to a left side of the vehicle body, and an intake duct and an exhaust duct for cooling air for cooling the battery are connected to an end of the battery box on a right side of the vehicle body. Therefore, it is possible not only to protect the battery between the left and right frames from a shock caused upon a side collision, but also to ensure a space for disposition of the intake duct and the exhaust duct while ensuring a volume of the battery box to the maximum. Moreover, the battery box is connected at its left and right ends to the left and right side frames.
