A lower structure for a vehicle includes a battery unit which is provided under a vehicle body floor, a frame member which extends in a front-rear direction on a vehicle-width-direction outer side of the battery unit, a high-voltage cable which extends forward from a front portion of the battery unit, and a fixing member which fixes a rear portion of the battery unit to the frame member, and the fixing member is configured to be fractured when an inward collision load in a vehicle width direction is input to a position in front of a position of a center of gravity of a first battery unit.

Lower structure for vehicle

A lower structure of a vehicle may include a transmission disposed in a floor tunnel, a rear propeller shaft that transmits power from the transmission to rear wheels, and left and right battery units disposed on the left and right sides of the floor tunnel, in which a rear portion (transfer) of the transmission is disposed in proximity to the portions on the front side and the upper side of the battery units, and inner protectors that cover inner side surface portions in the vehicle width direction of the battery units from the inner side in the vehicle width direction may be mounted to the front end portions of the inner side surface portions.

Lower structure of vehicle

A vehicle battery pack capable of suppressing a variation in cooling performance for a battery module by a cooling pipe. A vehicle battery pack includes a cooling pipe in a flat plate shape that abuts a lower surface of respective one of battery modules; and an elastic urging member that urges the cooling pipe upward to make the cooling pipe abut the lower surface of respective one of the battery modules. The elastic urging member has plural elastically-deformable legs that are aligned in a longitudinal direction of the cooling pipe.

Vehicle battery pack

A vehicle may include a propeller shaft that extends from a transmission toward a vehicle rear side and left and right battery units disposed below floor panels disposed on the left and right sides of a floor tunnel. The propeller shaft may include a first shaft portion connected to the transmission and a second shaft portion connected to the first shaft portion via a universal joint. The left and right battery units may have inner side surface portions that face the inner side in the vehicle width direction, respectively. Planar protectors that cover the portions of the inner side surface portions on the vehicle rear side of the universal joint may be mounted to the battery units, respectively.

Lower structure of vehicle having planar protector at inner side surface of battery unit

A vehicle battery pack capable of reducing a possibility of damage to a cooling pipe and suppressing reliability of cooling performance from being degraded. A vehicle battery pack includes two battery modules that are arranged at mutually adjacent positions; and a connecting pipe that communicates between two cooling pipes for respectively cooling the two battery modules. The connecting pipe connects in a manner to allow displacement of a relative position between the two cooling pipes.

A vehicle battery pack capable of improving distributivity of a refrigerant to a plurality of battery modules. A vehicle battery pack includes battery modules that are arranged in alignment in a vehicle width direction; two cooling pipes that cool the battery modules when being supplied with the refrigerant; and a flow divider that divides and supplies the refrigerant to the two cooling pipes. The flow divider is arranged between two battery modules in the vehicle width direction.
