A non-contact power feeding device includes multiple power feeding elements that are disposed spatially separated from one another in a movement direction, an AC power supply that supplies AC power to the power feeding elements, multiple power receiving elements that are provided in a moving body and that receive AC power in a non-contact manner, and a power receiving circuit that converts the AC power received by the power receiving elements and that outputs to an electrical load. When a length of the power feeding elements in the movement, direction is LT, a separation distance between the power feeding elements is DT, a length of the power receiving elements in the movement direction is LR, and a separation distance between the power receiving elements is DR, the relationship DTDR and the relationship (2LR+DR)LT are satisfied.

A monitor device is provided with an imaging device that shoots an overhead line and a current collector, and a controller that processes an image. The controller includes a day or night determination processing section, and an image processing section that switches a parameter for recognizing the overhead line and the current collector in the image by executing image processing different in the daylight and at night based upon the result of the day or night determination. Further, there are provided reference photographic subjects to be shot by the imaging device in positions different from the overhead line and the current collector in an image area to be shot, and the day or night determination processing section performs the determination of day or night based upon a luminance average value of the reference photographic subjects inputted into an image input section.

Systems of an electrical vehicle and the operations thereof are provided that use identifiers and sensed power source parameters to determine whether a rule, such as a warranty or licensing requirement, has been violated.

An apparatus comprises a first induction section comprising a first core and a first coil on the first core. A second induction section comprises a second core and a second coil on the second core. The first core comprises rail extensions, where at least two of the rail extensions extend from opposite ends of the first core. The second core comprises shoe portions located at respective ones of the rail extensions, where a gap is provided between each of the rail extensions and respective ones of the shoe portion. The second induction section is configured to move relative to the first induction section in a path along the extensions. The first induction section is configured to induce current in the second induction section, including when the second core moves relative to the first core along the extensions, to provide a contactless induction coupling between the first induction section and the second induction section.

A testing station for testing an industrial cart includes a controller, a length of track having a first section, a second section, and a third section. Sensors are communicatively coupled to the controller, where the sensors are configured to at least detect a cart traversing the third section. An electric source electrically coupled to the second section, where the second section provides electric power to a first pair of wheels of a cart when the cart traverses the first section and the second section, and the second section provides electric power to a second pair of wheels when the cart traverses the second section and the third section. An instruction set causes the processor to receive, from a first sensor, signals indicating the cart is traversing the third section and in response to receiving the signals indicating that the cart is traversing the third section, determine the cart is functioning.

Systems and methods for enabling fast charging of an electric vehicle at a charging station. An electric vehicle in positioned in a given location for charging and/or discharging. A charging arm comprising a plurality of charging brushes is then positioned relative to the position of the electric vehicle. The plurality of charging brushes on the charging arm is positioned to contact a charging interface of the electric vehicle. The charging brushes are moved relative to the charging interface such that a portion of the charging brushes is removed as a result of the movement.
