An electric work vehicle includes a carrier provided separately from a vehicle body for mounting/dismounting a battery, a carrier storage section provided in the vehicle body for attaching the carrier to the vehicle body, and an attachment mechanism for attaching/detaching the carrier to/from the carrier storage section.

An integrated high-performance and light-weight electric drive system for a bicycle is disclosed comprising an integrated unitary motor-controller-drive system that can be inserted into and removed from a first tube portion of a bicycle frame through an open bottom bracket shell portion of the bicycle frame. A longitudinally-extending battery pack configured to be electrically connected with and to provide electrical power to the electric motor and the controller may be configured to be inserted into and removed from a second tube portion of the bicycle frame through the open bottom bracket shell portion of the bicycle frame. Some or all of the electrical components may not be visible from the exterior of the bicycle. A unique digital torque sensing and control system is described along with regenerative braking and other unique features.

The present invention provides a battery-driven traveling device including: a framework section disposed on at least a bottom part of a vehicle body for ensuring strength of the vehicle body; two slide rails being composed of a left slide rail and a right slide rail and being supported by the framework section and extending substantially horizontally; a battery supporting member that is mounted to be insertable into the vehicle body and extractable from the vehicle body by using the two slide rails; and a plurality of dampers disposed on a path through which vibration of the vehicle body is transmitted from each of the slide rails to the battery supporting member for relaxing the vibration transmitted from the vehicle body to the battery while the device travels, wherein the left slide rail is disposed on left side of the battery supporting member and the right slide rail is disposed on right side of the battery supporting member, and each of the dampers is disposed above or below the left slide rail or the right slide rail.

A balancing apparatus of a vehicle includes: a load sensor installed in a seat of the vehicle to measure a weight of a passenger sitting on the seat; and a balance control apparatus that controls a center of gravity of the vehicle, when the balance control apparatus includes: a battery pack that supplies power to the vehicle, and the battery pack is movably installed on a frame module and moves to control the center of gravity of the vehicle based on a value measured by the load sensor.

A vehicle including: a floor panel; a pair of left and right front seats which are disposed on the floor panel; and a high-voltage battery which is disposed between the front seats and which is held on a frame member, wherein a guide member which guides the frame member is provided between the front seats on the floor panel, and wherein the guide member has a pair of left and right guide rails and a positioning portion which controls a position of the frame member in relation to the guide member in at least a front-rear direction.

A materials handling vehicle including a battery receiving space, and a removable battery assembly, wherein: the removable battery assembly includes lateral battery faces, each including a longitudinal guide structure; the battery receiving space includes opposing guide blocks, each arranged on opposite sides of the battery receiving space, and each including a securement portion and a replaceable portion; the replaceable portion of each guide block including a friction-inducing surface and a guiding surface; each friction-inducing surface facing an opposing one of the lateral battery faces; and each guiding surface facing an opposing surface of the longitudinal guide structure, with the removable battery assembly seated in the battery receiving space.

A vehicle includes a chassis, tractive elements coupled to the chassis, an electric motor coupled to the chassis and coupled to the tractive elements such that the electric motor drives the tractive elements to propel the vehicle, an accessory module coupled to the chassis and coupled to an output of the electric motor. The accessory module is configured to receive mechanical energy provided by the electric motor and provide at least one of electrical energy or fluid energy.

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.

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.

A two-way distribution, charging, and vending system permits a subscriber to exchange one or more partially or completely discharged portable electric energy storage devices for a comparable number of charged portable electric energy storage devices. The two-way distribution, charging, and vending system includes a number of charging modules, each with a dedicated power converter, communicably coupled to at least one two-way distribution system controller and to a power distribution grid. Upon receipt of a discharged portable electric energy storage device, the at least one two-way distribution system controller validates a manufacturer identifier and a subscriber identifier stored in a nontransitory storage media carried by the discharged portable electric energy storage device. Responsive to a successful authentication and validation, the at least one two-way distribution system controller dispenses a charged portable electric energy storage device to the subscriber.
