A stackable handcart includes a cart frame, a display, and a restriction member. The cart frame includes a receiving portion on which a shopping basket is placeable and a front end portion that abuts a first stackable handcart when the stackable handcart is stacked with the first stackable handcart from behind the first stackable handcart. The display is attached to the cart frame. The restriction member is attached to the cart frame at a position to abut a front end portion of a second stackable handcart when the second stackable handcart is stacked with the stackable handcart from behind the stackable handcart. The restriction member is positioned such that a display of the second stackable handcart does not abut the display of the stackable handcart when the front end portion of the second stackable handcart abuts the restriction member.

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.

A measurement apparatus includes a measurement circuit configured to measure a first current that flows to an electricity storage device and a second current that flows from the storage device, and a processor configured to detect one of a first state, in which the storage device is fully charged, and a second state, in which the storage device is fully discharged. The processor is configured to, upon detection of one of the first and second states, control the measurement circuit to start the measurement of the first current and the second current, calculate a remaining amount of power of the storage device using the measured first current and the measured second current, and output the calculated remaining amount of power.

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.

The display is attached to the cart frame. The restriction member is attached to the cart frame at a position to abut a front end portion of a second stackable handcart when the second stackable handcart is stacked with the stackable handcart from behind the stackable handcart. The restriction member is positioned such that a display of the second stackable handcart does not abut the display of the stackable handcart when the front end portion of the second stackable handcart abuts the restriction member.

A positioning apparatus for a mobile apparatus and a battery production line are provided. The positioning apparatus for a mobile apparatus includes: a locking rod arranged on the mobile apparatus, the locking rod being provided with an accommodating region; a bracket arranged at a preset place; and a locking block arranged on the bracket and having a first end that moves vertically in a gravity direction (y); wherein the locking block is configured to: when the mobile apparatus moves toward the bracket in a horizontal direction (x), the first end of the locking block is pushed by the locking rod to move upward, and when the locking rod moves to a preset position, the first end of the locking block falls into the accommodating region of the locking rod under the action of gravity to lock the locking rod.

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 service cart and associated apparatus that is suitable for servicing electric vehicles and vehicle batteries. The service cart may comprise a frame having a number of members that may be arranged in a compact configuration. The service cart may comprise a number of support pads that may be adjustably arranged with respect to the frame. The support pads may comprise an overload protection mechanism having a break pin. The service cart may comprise a detachable handle operable to selectively disengage a number of brakes on the cart. The service cart may comprise a tow hitch suitable for detachably coupling an external tow device.
