A battery pack and an electric vehicle are provided. The battery pack includes a cell array and two first reinforcing plates. The cell array includes a number of cells. Each of the cells is defined with a length L, a thickness D, and a height H between the length L and the thickness D. The number of cells are arranged along a thickness direction, and the cells are adhered to each other by a structural adhesive. The two first reinforcing plates are arranged opposite to each other and are respectively adhered to two surfaces of the cell array along the arrangement direction of the cells, and are configured to constrain relative positions between the cells.

An electric vehicle includes: a frame with two spaced-apart longitudinal members having an upper transversely oriented wall member that is situated a vertical distance Hu from a bottom plane and a lower transversely oriented wall member that is situated near the bottom plane, and a battery pack with an array of battery cells defining an array top surface, an array bottom surface and an array side surface. A casing top plate contacts the array top surface, a casing bottom plate contacting the array bottom surface and a casing side wall, connected to the top and bottom plates and contacting the array side surface. The casing top plate is situated a vertical distance Hct from the bottom plane that substantially corresponds with the distance Hu. The battery pack includes a longitudinal impact absorption structure.

A bottom structure for an electric vehicle including at least a first and second beam-shaped battery modules extending in a length direction. Each module is formed by a number interconnected cells and has two longitudinal sides, two transverse sides and a top side covered by a cover plate. The modules are mutually interconnected along their longitudinal sides via an adhesive.

A lateral surface member structure (100) of a vehicle body (1) includes a tubular body (110) extending in a front-rear direction of the vehicle body (1) and an impact absorbing member (120) disposed inside the tubular body (110). The impact absorbing member (120) includes a web (121) extending along the front-rear direction and flat in a vehicle width direction, a vehicle outer flange (122) joined to a vehicle outer end portion of the web (121) and extending along the front-rear direction, and a vehicle inner flange (123) joined to a vehicle inner end portion of the web (121) and extending along the front-rear direction. The vehicle outer flange (122) and the vehicle inner flange (123) each include a rib (122R, 123R) disposed so as to sandwich the web (121) from above and below and extending along the front-rear direction.

A lower structure for a hybrid automobile in which a high-voltage battery is disposed in a lower surface of a floor panel includes an engine exhaust system component which is disposed in front of the high-voltage battery in the lower surface of the floor panel and on one vehicle-width-direction side of a center in a vehicle width direction and high-voltage devices which are disposed in front of the high-voltage battery and on another vehicle-width-direction side of the center in the vehicle width direction. In-vehicle equipment is disposed between the high-voltage battery and the high-voltage devices, and the in-vehicle equipment is in an inclined state where an upper surface of the in-vehicle equipment is inclined in a front-rear direction such that the in-vehicle equipment has a shorter dimension in the front-rear direction than a dimension in a horizontal state where the upper surface becomes horizontal.
