A non-contact charging cart station includes a housing and a plurality of non-contact charging devices. The housing has a cart placement region on which stackable carts or the like can be inserted along a cart placement direction. The plurality of non-contact charging devices are in the housing and aligned in the cart placement region along the cart placement direction.

Electric trolley includes safety controller that determines whether or not to stop the driving of driving wheel, and driving commander that outputs, to the motor driver, (i) an operation permission signal for permitting motor to be operated and (ii) a control signal for controlling an operation of motor, in which safety controller performs control to stop inputs of the operation permission signal and the control signal to motor driver when the safety controller determines to stop the driving of driving wheel.

A non-contact charging cart station includes a housing and a plurality of non-contact charging devices. The housing has a cart placement region on which stackable carts or the like can be inserted along a cart placement direction. The plurality of non-contact charging devices are in the housing and aligned in the cart placement region along the cart placement direction.

A wheel assembly includes an attachment module, a motor module, a battery module, and a wheel. The wheel is rotatably coupled to the attachment module about a rotational axis of the wheel. The attachment module has a plurality of coupling elements, and the motor module and the battery module each releasably couple to one of the coupling elements. The wheel extends around the attachment, motor, and battery modules. The motor and battery modules are identically shaped in a direction along the rotational axis.

A current collector monitoring system in one aspect of the present disclosure is provided with: a collected current measurement unit; a collected current state determination unit; an image acquisition unit; an event recognition unit; an event determination unit; and a determination result output unit. When a state of collected current corresponds to an abnormal state, the image acquisition unit acquires an image including, within an angle of view, a collector shoe provided to a current collector.

A Power transmission system for transmission of electrical energy comprising a battery unit and a form of transportation to transport said battery unit wherein the transportation is comprised of a plurality of train cars carrying said battery unit and at least one rail track system to which the railcars travel on and further where the railcars are comprised of plurality of battery modules which are comprised of plurality of battery packs which are comprised of plurality of battery cells and a battery pack management system.

A vehicle power delivery assembly that includes a mast configured to couple with a vehicle such that the mast projects from the vehicle, and a collection arm configured to be coupled with the mast in a location apart from the vehicle to engage an off-board source of electric current that is off-board the vehicle while the vehicle moves along one or more routes. One or more of the mast or the collection arm is formed from at least one inductive support member that provides an integrated inductor of the one or more of the mast or the collection arm through which at least some of the electric current that is received from the off-board source of the electric current is filtered prior to being conducted to the vehicle.

An information processing apparatus controls a vehicle having a service power supply used to provide a service and a driving power supply used for traveling. The information processing apparatus has a storage unit configured to store service-related information concerning the service provided by the vehicle, and a controller configured to select any of a first mode, in which the service power supply and the driving power supply are independently used, and a second mode, in which the service power supply and the driving power supply are shared, based on the service-related information.

A transport robot may include a wheel driver, a power supply, and a processor. The transport robot may execute artificial intelligence (AI) algorithms and/or machine learning algorithms, and may communicate with other electronic devices in a 5G communication environment. Thus, user convenience can be improved.

A combination vehicle includes a tractor and a trailer towed by the tractor. The trailer includes a first tank that is configured to store a high-pressure gas as a fuel used by the tractor to travel. The tractor includes a second tank that is configured to store a high-pressure gas as a fuel used by the tractor to travel. The combination vehicle is configured to travel using the fuel supplied from the first tank and the second tank.
