A vehicle includes a body including a rocker, the rocker being located outside a floor panel in a vehicle width direction and extending in a front-rear direction. The vehicle further includes a battery unit located under the floor panel and detachably attached to the body from below. The vehicle further includes a bracket fixed to the rocker. The vehicle further includes a pipe or wire fixed to the bracket, located outside the rocker or the battery unit in the vehicle width direction, and extending in the front-rear direction of the body. The vehicle further includes a rocker molding extending from a position facing an outer side surface of the rocker to a position facing a lower surface of the battery unit, the rocker molding covering an outer side of the pipe or wire in the vehicle width direction.

A traction battery assembly according to an exemplary aspect of the present disclosure includes a lower tier of battery arrays, an upper tier of battery arrays, and a support structure disposed between the lower tier and the upper tier. The lower tier is suspended from a downwardly facing side of the support structure. The upper tier is disposed atop an upwardly facing side of the support structure.

A tractor trailer battery system having a battery compartment containing one or more battery units which house one or more battery cells, electrical leads from the battery units to a trailer mounted controller in electrical communication with a cab mounted controller which is in electrical communication an electric motor or hybrid engine system. The battery system allows for either the trailer mounted controller or the cab mounted controller to provide principal communication to the electric motor or hybrid engine system.

A system can prevent burning of a vehicle or human injury caused by a fire spread from a battery to a vehicle in the event of a fire in the battery of an eco-friendly vehicle. The system can release a battery from the vehicle such that the battery can be separated and removed from the vehicle when a fire occurs in the battery. The system is operated in response to a control signal of a controller detecting the fire in the battery and by manipulation of a driver, and releases a state of the battery mounted to a vehicle body to release the battery from the vehicle such that the battery can be separated or removed from the vehicle.

Disclosed is a battery unlocking control method, a battery locking control method and an electric vehicle battery swapping control method. The battery locking control method comprises the following steps: moving the battery to the fixing base to enable the lock shafts to enter the lock slots; after the lock shafts enter the lock slots, detecting the locations of the lock shafts, and moving the battery until the lock shafts arrive at locking locations; and with the lock tongues falling, snapping the lock shafts into the lock slots. By providing various location detection components, the battery is accurately located and locked when being loaded into a fixing base, and then accurately located and unlocked when being removed from the fixing base, thereby achieving full-automatic control during swapping of the battery and improving the swapping speed and success rate of the battery.

A battery assembly is disclosed that includes a battery housing, a battery array, and one or more cooling plates. The battery housing forms a battery compartment having a width and length greater than a height. The battery array includes a plurality of cylindrical battery cells oriented with an axis perpendicular to the height of the battery compartment. The plurality of cells are organized into a plurality of rows within the battery compartment. The one or more cooling plates oriented perpendicular to the axis of the battery cells and positioned proximal to an end of battery cells within a row of the plurality of rows.

There is provided a vehicle lower section structure including: a frame member that includes a pair of rockers, a front cross member coupled to the pair of rockers through a front coupling member, and a rear cross member coupled to the pair of rockers through a rear coupling member; an intermediate cross member that extends in the vehicle width direction between the front cross member and the rear cross member and that is coupled to the pair of rockers; and a bridging member that includes a rear portion located at a vehicle rear of the bridging member and joined to the rear cross member or the rear coupling member, and that includes a front portion located at a vehicle front of the bridging member and joined to one of the rockers, the front cross member, the front coupling member, or the intermediate cross member.

A vehicle includes: a vehicle interior; a front room provided on a front side of the vehicle interior; a luggage room provided in a rear side of the vehicle interior; a weight part which includes at least one of a drive unit to drive a vehicle wheel and a power source to supply fuel or power to the drive unit; and a battery. The weight part includes a first weight part and a second weight part, at least one of the first weight part and the second weight part includes the drive unit, the battery is provided below the vehicle interior, the first weight part is provided in the front room, the second weight part is provided below the luggage room, and a height of the second weight part is lower than a height of the first weight part.

A side sill structure included in a substructure of a vehicle body, includes a battery pack disposed below a floor panel, a side sill disposed at an outer part in a vehicle width direction and extending in a front-rear direction of the vehicle body, and a stiffener disposed inside a cross section of the side sill and extending along an extending direction of the side sill. The stiffener is composed of an outer stiffener bulging outward in the vehicle width direction, and an inner stiffener bulging inward in the vehicle width direction. In the side sill structure, a first side surface of the stiffener, formed on the inner stiffener, is shifted to a relatively upper side than a second side surface of the stiffener, formed on the outer stiffener, and the battery pack is supported on a lower surface of the side sill.

This disclosure details electrified vehicles that are equipped with pass through assemblies for structurally reinforcing and sealing battery packs. An exemplary pass through assembly includes clean-side component and a dirty-side component. The clean-side component is positioned primarily inside the battery pack, and the dirty-side component engages the clean-side component and extends to a location outside of the battery pack for interfacing with a component of the vehicle underbody. A seal of the pass through assembly is positioned between the clean-side component and the dirty-side component and is configured to block the ingress of water, dirt, and other potential contaminants.
