A vehicle body structure for an electric vehicle includes: a battery disposed at a center lower portion of a vehicle body; a side sill being hollow and extending in a vehicle body front-rear direction outside in a vehicle width direction of the battery; a bridge beam member being hollow, disposed below the side sill and outside in the vehicle width direction of the battery, extending in the vehicle body front-rear direction, and having a cross section perpendicular to the vehicle body front-rear direction formed as a closed cross section; and at least one bridge pier member made of steel, extending in the vehicle width direction from the battery toward the bridge beam member, and having a cross section perpendicular to the vehicle width direction forming at least a part of a closed cross-sectional shape.

Vehicle body structure for electric vehicle

A vehicle body structure includes: a battery disposed at a vehicle body central lower portion, i.e., at a central lower portion of the vehicle body; a side sill of a hollow shape, the side sill disposed at an outer side of the battery in a vehicle width direction and extending in a vehicle longitudinal direction; a reinforcement member disposed inside the side sill, having a closed cross section of a polygonal shape, and having a continuous cylindrical structure where a plurality of the closed cross sections are continuous when viewed in the vehicle width direction; and a deformation control member attached to the reinforcement member and configured to control a deformation of the continuous cylindrical structure of the reinforcement member in the vehicle longitudinal direction.
