Techniques are described for aligning a vehicle to a wireless charger. Wireless communication is performed between at least a first wireless device of the vehicle and at least a second wireless device external to the vehicle. The first wireless device has a stationary position relative to the vehicle. The second wireless device has a stationary position relative to the wireless charger. Based on the wireless communication, a distance between the first and second wireless devices is measured and used to determine the relative position of the vehicle. A trajectory is calculated, based on the relative position of the vehicle, to enable the vehicle to be maneuvered into a charging position in which a charge receiving device of the vehicle is aligned with respect to the wireless charger. In some embodiments, multiple wireless devices on the vehicle or external to the vehicle participate in determining the relative position of the vehicle.

A working machine is provided, comprising a working machine frame structure, at least one electric machine configured to propel the working machine, a re-chargeable energy storage system electrically connected to the at least one electric machine, the at least one electric machine being operable by electric power received from the re-chargeable energy storage system, a load implement body configured to receive a load and being pivotably connected to the working machine frame structure at a pivot joint, and an electrical charge element electrically connected to the re-chargeable energy storage system, the electrical charge element being arranged on a surface portion of the load implement body and configured to, in a charging state, receive electric power from a vertically elevated power source, wherein the working machine is configured to bring the electrical charge element into the charging state by rotation of the load implement body around the pivot joint.

An external appearance image of a power transmission unit of a wireless power supply device is registered in a parking assist apparatus in association with identification information on the wireless power supply device. The parking assist apparatus superimposes and displays a target parking area image on a parking space image showing a parking space, and superimposes and displays the external appearance image associated with identification information having the same content as the identification information acquired from the wireless power supply device by wireless communication at a position corresponding to an installation position of the power transmission unit on the parking space image.

An adjustment system causes a target power supply device to execute first processing and second processing while causing at least one adjacent power supply device to perform a regular power supply operation. The first processing is processing for measuring a first voltage value while a power supply circuit of the target power supply device does not output an alternating current. The second processing is processing for measuring a second voltage value while the power supply circuit of the target power supply device outputs an alternating current. The adjustment system obtains a feeder circuit reactance of a feeder circuit based on the difference between the first voltage value and the second value, and executes adjustment processing for adjusting circuit characteristics with use of an adjustment unit in accordance with the obtained feeder circuit reactance in such a manner that the feeder circuit impedance is a predetermined impedance.

A power feeding station according to one or more embodiments may include a feeder including a feeder coil that feeds power to a receiver in an electric mobility vehicle, a power supply circuit that supplies AC power to the feeder coil, and a control circuit that controls a frequency and a voltage of the AC power. The control circuit provides, through a notification source a notification of guidance about a stop position of the electric mobility vehicle relative to a housing to increase power transmission efficiency from the feeder to the receiver in accordance with the frequency of the AC power supplied to the feeder coil with which the receiver outputs a constant voltage or in accordance with the voltage of the AC power supplied to the feeder coil with which the receiver outputs a constant and predetermined voltage.
