An electric work vehicle includes a plurality of battery mounting portions, a plurality of battery packs that can be detachably mounted to the battery mounting portions, a main body contact provided for each one of the battery mounting portions and electrically connected with the battery back mounted to the battery mounting portion, a power feeding circuit to which the main body contact is parallel connected, a battery switch configured to block flow of electric power from the battery pack to the power feeding circuit, a switch operating portion for operating the battery switch, a charged amount estimating portion for estimating a charged power of the battery pack mounted to the battery mounting portion, an electric motor driven by power fed from at least one battery pack via the power feeding circuit, and a driving wheel receiving power transmitted from the electric motor.

An electric work vehicle includes: a battery accommodating portion that is provided in the vehicle body and accommodates a battery; a first connector provided on the battery accommodating portion; a second connector provided on the battery; and an operating tool for moving the battery and the second connector, and switching from a pre-attachment orientation in which the second connector opposes the first connector to an attachment orientation in which the second connector is joined to the first connector.

A vehicle bottom structure includes a floor panel, a battery mounted on the floor panel, a deck board, and an inclined portion. The inclined portion is arranged adjacent to the battery. The inclined portion is inclined such that, in a direction parallel to a mounting surface of the floor panel, the inclined portion rises as a distance from the battery increases. The inclined portion includes an end facing the battery. The end is located above a lower surface of the battery and below half the height of the battery.

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.

A battery changing system includes a grasping assembly and an actuation assembly. The grasping assembly is configured to be disposed onboard a vehicle and to engage a battery box having one or more batteries disposed therein. The actuation assembly is configured to move the grasping assembly away from the vehicle toward the battery box. The actuation assembly also is configured to move the grasping assembly into engagement with a securing assembly of the battery box. The actuation assembly is configured to move the grasping assembly back toward the vehicle while the grasping assembly engages the securing assembly of the battery box to lift the battery box onto the vehicle.

A tray glide system includes a frame having opposite sides, and a base defining an interior, where a tray slides relative to the frame. Glide mounts formed of ultra-high molecular weight polyethylene are attached to the base in the interior, and are located under the tray providing sliding of the tray relative to the frame. Glide rails are engaged to the bottom of the tray and are shaped to engage one or more surfaces of the slide mounts. Each of the glide rails includes a bearing ledge proximate to one of the opposite sides of the frame. An upper guide rail is attached to each of the opposite walls. Each upper guide rail has a horizontal retaining ledge positioned above one of the bearing ledges, to engage the bearing ledges, and to prevent downward pivoting of the tray during withdraw of the tray from the frame.

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.

In an embodiment, a battery module compartment chamber is configured for deployment with one or more other battery module compartment chambers within a battery module mounting area of an energy storage system. The battery module compartment chamber includes exterior walls and at least one interior firewall that define multiple battery module compartments into which battery modules may be inserted and/or removed. Each battery module compartment includes an insertion-side configured to be closed via a respective insertion-side cover to seal the respective battery module compartment. In a further embodiment, the battery module compartment may be stacked longitudinally with one or more other battery module compartment chambers to form a battery module mounting area. A type of the battery module compartment chamber and/or a number of longitudinally stacked battery module compartment chambers may be selected to satisfy a size requirement for the battery module mounting area.

An embodiment is directed to a battery module mounting area of an energy storage system. The battery module mounting area includes a first set of battery module compartments arranged along a first longitudinal side of the battery module mounting area, and a second set of battery module compartments arranged along a second longitudinal side of the battery module mounting area. Each battery module compartment in the first and second sets of battery module compartments includes an insertion-side through which a battery module is configured to be inserted into the battery module compartment and/or removed from the battery module compartment. The insertion-side of each battery module compartment in the first and second sets of battery module compartments is configured to be closed via an insertion-side cover to form a battery housing with a closed compartment profile that is characterized by each battery module compartment being sealed from at least one other battery module compartment in the battery housing.

In an embodiment, a battery module compartment is configured for deployment with one or more other battery module compartments within a battery module mounting area of an energy storage system. The battery module compartment includes aa plurality of walls defining an interior space configured to fit a battery module, and an insertion-side through which the battery module is configured to be inserted or removed. The insertion-side is configured to be closed via an insertion-side cover to form part of a battery housing with a closed compartment profile that is characterized by the battery module compartment being sealed from at least one other battery module compartment in the battery housing.
