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 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.

A battery device for a vehicle, which can be miniaturized while including ancillary instruments such as a relay device. The battery device is mounted in a lower portion of a vehicle, and including a battery case; a plurality of battery modules accommodated in the battery case and arranged such that at least some of the battery modules are stacked in a plurality of levels; and a first relay device that switches connection and disconnection between external electric devices and the battery modules. The first relay device is disposed on a side in a vehicle width direction of a portion where the battery modules are stacked in a plurality of levels.

Battery device for vehicle

A structure of an intake manifold () for an engine is constituted of divided pieces (). The structure of the intake manifold includes a gas supply hole () formed in a predetermined position of an outer surface of the intake manifold, and configured to supply predetermined gas from the outside, and a gas inlet passage () formed in predetermined joint surfaces () of the divided pieces (), and configured to guide the gas supplied through the gas supply hole to a predetermined gas inlet position () of an intake passage (E).
