Patent 7913787 was granted and assigned to Toyota on March, 2011 by the United States Patent and Trademark Office.
A power source pack is arranged on a floor in such a manner that the vehicle front side is positioned higher than the vehicle rear side. Specifically, the front side of the power source pack is placed on a cross member qualified as a structural member that is fixed to traverse the vehicle on the floor. By such a configuration, it is possible to provide a structure for mounting a power source pack that is configured to be less vulnerable to the heat penetrating from a lower surface of the floor to the interior of a cabin even if the power source pack is arranged on the floor.
