The present disclosure is directed to battery cart for transporting large and heavy electric car batteries. The cart includes a pair of independently movable and positionable cart half assemblies, with each cart half assembly having a pair of battery supports that are slidably positionable and lockable along a center crossbar. Each support includes height adjustable columns. The cart assemblies therefore, are adjustable to support batteries of varying sizes as well as positioning a supported battery to desired height, facilitating repairs to, and transport of, the electric car battery.

Disclosed are mobile battery powered workstations, methods of operating these workstations to increase warehouse and retail efficiency (through improved order fulfillment, as a mobile shipping & receiving station, mobile inventory management, and/or as mobile powered quality analysis stations), and methods of calculating remaining battery runtime for these workstations. A mobile battery powered workstation may comprise a wheeled base having a modular battery power bay, an upper workstation having a monitor, a computer, a printer, and at least one adjustable height column coupling the wheeled base to the upper workstation. The workstation may also include a glass overlay display positioned on a top surface of the upper workstation area and configured to provide order fulfillment employees with haptic feedback on remaining battery runtime, calculated via an algorithm for increased accuracy. These workstations may be used in warehouses and retail operations for order picking and fulfillment, shipping and receiving tasks, etc.

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.

In one embodiment, a power storage system includes a movable cart, an external frame, a rechargeable battery, and an electronic system. The movable cart includes a support frame. The support frame includes a base, a plurality of sidewalls mounted vertically with respect to the base, a lid mounted with respect to the plurality of sidewalls, and a set of wheels mounted with respect to the base. The external frame is mounted with respect to the base and is configured to extend around the plurality of sidewalls, where the plurality of sidewalls are accessible from a position outside of the external frame. The electronic system includes at least one output electrical receptacle and at least one input electrical receptacle. The electronic system is configured to electrically connect with the rechargeable battery, and the rechargeable battery and the electronic system are mounted with respect to the movable cart.

A backpack for stowing and carrying a smart self-balancing electric scooter is provided. The backpack includes a tubular shaped body defining an interior compartment sized to fit a self-balancing electric scooter compactly therein. A pocket disposed in the interior compartment receives the scooter's battery and a slot disposed in the body provides a power cord access to the interior compartment, such that the scooter may be charged while stowed in the backpack. A flame retardant layer lining the interior compartment extinguishes any fire caused by the scooter battery, while the scooter charges in the backpack. An access flap and an access collar provide access to the interior compartment for stowing the scooter. A shoulder harness enables the backpack to be carried and a retractable handle and a plurality of multidirectional wheels enable the backpack to be towed while the scooter is stowed therein.

A fuel cell assembly for easy removal and installation of a fuel cell system is described. The fuel cell assembly includes one or more first rolling members provided in one or more first slots of a first base arrangement, where a plurality of holes are configured on a second surface of the first base arrangement. Each of the one or more first rolling members includes a plurality of rollers configured to be inflated and deflated. The inflating and deflating of each first rolling member facilitate movement of the plurality of rollers of each first rolling member into a plurality of holes and out of the plurality of holes, respectively, which enables the fuel cell system to move between a raised position and a lowered position. The raised position of the fuel cell system indicates a position in which the fuel cell system is in contact with the plurality of rollers.

A battery transportation equipment to transport a plurality of backup batteries. The battery transportation equipment includes: rollers, an equipment body, a battery cavity and a cooling device. The rollers are connected to the equipment body; the battery cavity is formed by an inward recess of the equipment body; the battery cavity is used to accommodate the plurality of backup batteries and is provided with a pairs of outwardly extending power plugs. The power plugs are used to plug-connect with the power jacks of the backup battery. The cooling device surrounds the battery cavity to dissipate heat when the plurality of backup batteries are being charged.

A backpack for stowing and carrying a smart self-balancing electric scooter is provided. The backpack includes a tubular shaped body defining an interior compartment sized to fit a self-balancing electric scooter compactly therein. A pocket disposed in the interior compartment receives the scooter's battery and a slot disposed in the body provides a power cord access to the interior compartment, such that the scooter may be charged while stowed in the backpack. A flame retardant layer lining the interior compartment extinguishes any fire caused by the scooter battery, while the scooter charges in the backpack. An access flap and an access collar provide access to the interior compartment for stowing the scooter. A shoulder harness enables the backpack to be carried and a retractable handle and a plurality of multidirectional wheels enable the backpack to be towed while the scooter is stowed therein.

Battery systems containing recyclable battery portions. The present disclosure includes disclosure of a battery system, comprising a housing configured to retain two or more battery portions; two or more battery portions configured to fit within the housing; wherein the housing is configured to fit within a battery compartment of a cart; wherein the two or more battery portions, when effectively connected together using a central connector of the battery system, collectively produce sufficient power to power electronic equipment of the cart; and wherein each of the two or more battery portions weigh at or below a desired threshold weight.

A service cart for an electric vehicle (EV) battery, comprising a lift assembly supporting a platform. The platform is configured to support the EV battery. The service cart comprises an electrically-driven hydraulic pump that is configured to extend and retract the lift assembly in order to raise and lower the platform. The service cart may comprise one or more electric wheels which may be driven by rotational force from a first electric motor, or controlled with respect to an adjustable directionality by a second electric motor.
