A battery for an electric drive of a motor vehicle, including a plurality of battery modules which are arranged in an associated layer and are accommodated in at least one associated battery housing. In order to produce a battery which is optimized both in terms of its manufacture and also in terms of sealing tightness and properties in the event of a crash, the battery housing is accommodated in a protective housing of the battery.

The present disclosure provides a vehicle lower portion structure including: a case main body portion, disposed at a vehicle lower side of a vehicle cabin floor and including a bottom wall and peripheral walls that extend toward a vehicle upper side from a peripheral edge portion of the bottom wall, and accommodating a battery at an interior thereof; a front portion extending portion formed integrally with the case main body portion at a vehicle front side of the case main body portion, at the peripheral wall that is at a vehicle front side of the case main body portion; and an impact absorbing portion, extending in a vehicle longitudinal direction and deforming due to input of collision load from a vehicle front side, a rear end portion of the impact absorbing portion being connected to a vehicle front side region of the front portion extending portion.

A vehicle comprising: at least one electric motor configured for driving the vehicle; a battery pack configured to supply the electric motor with electric power for driving the vehicle; a vehicle body frame structure configured to form a main supporting structure of the vehicle; and a collision energy absorbing system configured to absorb collision energy in the event of an accident. The collision energy absorbing system comprises a first absorbing structure that is positioned between the battery pack and a front of the vehicle, wherein the first absorbing structure is configured to, in case the vehicle is subject to a head-on collision with an object, act against the object and absorb all or most of a collision energy of the battery pack without transferring the battery pack collision energy to the vehicle body frame structure.

A fuel cell vehicle includes a first high-voltage unit and a second high-voltage unit in a front compartment. The first high-voltage unit includes a first case including a body portion, and a projecting portion that projects from an outer surface of the body portion, and is located between a pair of suspension towers, and between a dashboard panel and a front bumper. The second high-voltage unit is placed in space between one of the suspension towers and the dashboard panel. The projecting portion projects toward the one suspension tower, and at least a part of the projecting portion is located on the front side in the traveling direction, relative to a straight line connecting center axes of the suspension towers, as viewed from the top of the vehicle.

A vehicle front portion structure that includes: a suspension member that is provided further toward a vehicle front side than a battery accommodating portion, and that has a pair of side rails that are disposed with an interval therebetween in a vehicle transverse direction and that extend in a vehicle longitudinal direction; and connecting members that connect rear portions of the side rails and a front portion of the battery accommodating portion, and at which deforming portions that, due to input of collision load to the side rails from a vehicle front side, deform such that the rear portions of the side rails move toward a vehicle lower side with respect to the front portion of the battery accommodating portion are formed, the connecting members being formed by members having higher ductility than the side rails.

A fuel cell vehicle includes a fuel cell module accommodated in a fuel cell accommodation space disposed in a front portion of the vehicle, a hydrogen circulation flow path configured to recirculate anode off-gas that is discharged from a fuel cell constituting the fuel cell module to the fuel cell, and a hydrogen pump provided in the hydrogen circulation flow path and fixed to a lower portion of the fuel cell module. The hydrogen pump is fixed to the fuel cell module via a bracket and the deformation strength of the bracket is set to be lower than a load input from a wall portion behind the fuel cell accommodation space at the time of collision of the vehicle.

The high voltage electric equipment unit is mounted in between left and right side frames of a vehicle body, and is disposed so that at least a portion of an outer side surface of the unit case in a vehicle width direction faces an inner side surfaces of the side frame in the vehicle width direction. A protective structure includes a plurality of contact surfaces formed on the outer side surface of the unit case in the vehicle width direction, a flat section formed in a region surrounded by the plurality of contact surfaces of the outer side surface so as to protrude outward in the vehicle width direction with respect to other area inside the region, and a plate-shaped guard member fixed to the plurality of contact surfaces and facing the flat section via a predetermined gap.

A battery assembly for a vehicle including a battery pack and a platform supporting the battery pack. A tubular sled runner is longitudinally oriented to absorb collision forces in a frontal collision. The sled runner defines first and second coolant supply channels on opposite lateral sides of a central coolant return channel. A coolant circulation system provides coolant to the first and second coolant supply channels and receives coolant from the central coolant return channel. A coolant loop is disclosed for cooling another heat source with the coolant flowing through the sled runner. Longitudinally extending ribs may be provided on the inner side, outer side, or both sides of the sidewalls of the sled runner to increase crush resistance or heat transfer efficiency.

A vehicle power source system includes a plurality of module groups each including a plurality of battery modules and disposed separately from each other, and a cooling circuit including a plurality of module group cooling units which are configured to respectively cool the plurality of module groups. The plurality of module group cooling units are connected in series. Each of the plurality of module group cooling units includes a plurality of module cooling units, each of which is configured to cool one or more of the battery modules. In each of the plurality of module group cooling units, the plurality of module cooling units are connected in parallel.
