An electrical vehicle including a vehicle body, a passenger compartment, a chassis supporting the passenger compartment, a plurality of wheels and at least one electrical motor for driving the wheels. A battery compartment of the vehicle is configured to removably mount therein a plurality of more than two rechargeable batteries which are movable into position in the battery compartment by a battery conveyor system which has a battery access opening through which batteries are installed or removed, one by one, to and from the battery compartment. In the battery compartment, a connection mechanism effects the needed mechanical and electrical connections. An overall control system controls the conveyor system and the connection mechanism to enable rapid replacement of the removable batteries, whereby an electrical vehicle can be instantly driven, even after its batteries have been discharged by a replacement of the discharged batteries and the installation of freshly charged batteries.

A machine may include a frame and a lift system. The lift system may include a lift arm attached to the frame. The lift arm may be configured to actuate between a raised position and a lowered position. The lift system may include a roller attached to the frame. The machine may include a power unit including an energy storage unit and a power unit housing containing the energy storage unit. The power unit housing may include an engagement element configured to engage the power unit housing with the lift arm. The power unit housing may include a cam element, projecting from the power unit housing, configured to slidably engage with the roller during actuation of the lift arm.

A floor module is provided for installation in the rear area of a motor vehicle. A rear area of the floor module facing the tail of the vehicle includes a first plastic composition, and a front area facing away from the tail includes a second plastic composition, wherein the first plastic composition imparts a higher elastic deformability to the rear area than to the front area.

Methods and systems are provided for cooling a hydrogen fuel cell assembly. A vehicle system, in one example, includes a hydrogen fuel cell assembly electrically coupled to a traction motor, positioned behind a cab, and including a plurality of hydrogen storage tanks and hydrogen fuel cells. The vehicle system further includes a fuel cell cooling assembly including an inlet manifold in a deflector, where the deflector is fixedly coupled to and positioned vertically above the cab and designed to direct airflow to a fan array that is coupled to a fuel cell assembly heat exchanger, where the fan array is positioned behind inlet manifold and longitudinally offset therefrom.

A mounting structure for a series of electric battery packs (21); such packs get mounted between the two lateral chassis rails (11, 12) of a medium or heavy-duty electric vehicle. The battery packs get inserted through either the forward-facing or rear-facing ends of the chassis frame. Such chassis frame is created by joining a set of double up frame rails (11, 12) together with U-shaped cross members (32), allowing access to the interior of the chassis frame, and allowing a simplified removal and replacement of batteries for maintenance purposes.

An energy store floor system for an electrically drivable motor vehicle includes a floor structure having respective side sills, to the underside of which is fastened a store housing of an energy store for an electrical drive of the motor vehicle, and having respective profile elements, which are arranged along longitudinal sides of the store housing and are fastened to the underside of the respectively assigned side sill. In order to create an energy store floor system with an improved accident behavior in the event of a side impact, the profile elements are connected to the respectively laterally assigned side sill via respective connection devices, which are detachable from the outside inwards when there is a relative movement, caused by an accident, of the respective side sill relative to the assigned profile element in the vehicle transverse direction.

An unlocking assembly for unlocking a battery pack (400) in an electric vehicle is disclosed. The electric vehicle is provided with a locking mechanism (200), and the battery pack (400) is locked and connected to the electric vehicle by means of the locking mechanism (200). The unlocking assembly comprises: a first unlocking portion (100) arranged in the battery pack (400) and configured to drive the locking mechanism (200) to move to an unlocking position to unlock the battery pack (400); and a second unlocking portion (300) arranged on a battery swapping device (10) and configured to move the first unlocking portion (100) that is located at an initial position in the battery pack (400) to an extended position in a vertical direction to unlock the battery pack (400).

Various personal mobility vehicles, such as scooters, are disclosed. The scooter can include at least one battery and motor for powering at least one driven wheel. The vehicle can include a gear assembly to convert a torque produced by the motor to a different torque to a driven shaft to power the at least one driven wheel. The battery can be removable.

An electric vehicle (EV) battery unit and installation method is provided herein. The EV battery unit includes a modular housing with a central section with batteries positioned therein and a first lateral section with a battery cooler that is designed to reduce a temperature of the batteries and an inverter that is positioned therein and electrically coupled to the batteries. The modular housing further includes a first frame attachment interface profiled to attach to a first longitudinal frame rail in an EV and a second frame attachment interface profiled to attach to a second longitudinal frame rail in the EV, where the batteries are positioned laterally between the first and second frame attachment interfaces.

An electric work vehicle includes an electric work machine including a battery mounting unit on which a battery is detachably mountable; a battery housing unit supported by at least one wheel and configured to house the battery; and a battery carrier including the at least one wheel and a manual push handle configured to be manually pushed to move the battery housing unit. The battery housing unit is detachably mountable on the battery mounting unit for the battery to be mounted on the battery mounting unit, and the at least one wheel and the manual push handle are separable from the battery housing unit.
