[0003] However, in the above-mentioned Patent Document 1, the connection portions (joint portions) on the extended side members of the battery pack are only arranged at appropriate intervals in the front-rear direction of the vehicle, so the battery pack does not contribute to improving the torsional rigidity of the vehicle body. The joint of the heavy battery pack may instead reduce the torsional rigidity of the vehicle body

Abstract

A battery unit (21)comprises plural side connection portions (48, 49)which are provided at its both-side end portions in a vehicle width direction and connected to said vehicle-body member, and these connection portions are connected to a high rigidity portion of a vehicle-body member, concretely, to the vehicle-body member at a specified position where floor cross members (13, 14) integrally connected to a vehicle floor panel (1) are located, to the vehicle-body member at a specified position where a torque box (15)is located, or to the vehicle-body member at a specified position where a kick-up portion of the vehicle floor panel is located. Accordingly, the torsional rigidity of the vehicle body can be increased by utilizing the battery unit (21) mounted below the vehicle body floor (vehicle floor panel).

Description

technical field [0001] The present invention belongs to the technical field related to a battery mounting structure of an electric vehicle in which a battery module is mounted on the lower side of a vehicle compartment floor. Background technique [0002] Generally, in an electric vehicle such as an electric automobile, a plurality of battery modules are mounted under a vehicle floor in a combined state. Such battery assemblies are typically joined to body components. For example, in Japanese Patent Laid-Open Publication No. 2006-224877 (Patent Document 1), the frame of the cell assembly including the fuel cell is arranged to straddle the bottom walls of a pair of extended side members extending from the rear side of the vehicle body of the front side members. The above state setting, the frame of the battery assembly is connected to the extended longitudinal beam by connecting bolts at a plurality of positions in the length direction. [0003] However, in the above-mentio...
