A driving force transmitting device includes an axle housing and a transaxle main body. The axle housing includes a supporting body and two shafts extending in opposite directions from the supporting body. The supporting body has an internal space. The transaxle main body is supported by the supporting body. The axle housing further includes a first breather plug. The first breather plug is fixed to the supporting body and is configured to discharge a gas in the internal space to an outside. The transaxle main body includes a gear mechanism, a case that accommodates the gear mechanism, and a second breather plug. The gear mechanism is configured to transmit a driving force. The second breather plug is fixed to the case and is configured to discharge a gas in the case to the outside. The second breather plug is located in the internal space.

Vehicle battery pack comprising a support structure comprising, in turn, at least two elongated perimeter members facing one another and defining, between them, a box portion; several bulkheads arranged so to divide the box portion delimiting at least two housings, wherein the bulkheads are arranged transversely to the two perimeter elements facing one another; a plurality of planar, electrically connected electrochemical cells parallel both to one another and to the bulkheads and divided into at least two modules, wherein said at least two modules each comprise at least two insertion plates arranged at the ends of each module, parallel to the bulkheads, and configured to facilitate the insertion of each module under compression into the respective housing, so that the compression remains even after the insertion.

A detection device configured to detect a decrease in heat insulation performance of a battery pack mounted at an electrically powered vehicle, the detection device including: a heat insulation performance derivation unit configured to derive a heat insulation performance value, which is an evaluation value of the heat insulation performance, based on a temperature change of the battery and an environmental temperature in a predetermined period in which the electrically powered vehicle is stopped; a determination unit configured to determine, based on the heat insulation performance value derived by the heal insulation performance derivation unit and a predetermined reference value, whether the decrease in the heat insulation performance occurs; and an output unit configured to output, when the determination unit determines that the decrease in the heat insulation performance occurs, detection information indicating that the decrease in the heat insulation performance occurs.

An electric vehicle includes a first rocker and a second rocker spaced from each other. A first slider is slideably engaged with the first rocker, and a second slider is slideably engaged with the second rocker. A first pyrotechnic actuator is supported by the first rocker and is configured to slide the first slider relative to the first rocker. A second pyrotechnic actuator is supported by the second rocker and is configured to slide the second slider relative to the second rocker. A cable extends from the first slider to the second slider.

An embodiment skateboard platform for an electric vehicle includes a skateboard frame including a center module, a front module connected to a front of the center module, and a rear module connected to a rear of the center module, and a battery assembly mounted on the skateboard frame, wherein the battery assembly is detachably connected to the center module.

A vehicle includes a body including a first frame rail and a second frame rail and a cross-brace directly connected to the first frame rail and the second frame rail. A powertrain-electrification component is supported by the cross-brace. A vehicle subframe is directly connected to the cross-brace. A vehicle-steering gear is connected to the subframe. The direct connection of the subframe to the cross-brace dampens vibration, e.g., road vibration and noise, in the subframe to reduce noise, vibration, and harshness transferred to a vehicle occupant through the vehicle-steering gear.
