A driver assistance system aids a driver in charging one or more trailer-mounted batteries in a trailer being towed by an electrified passenger vehicle. Many existing charging facilities for electric vehicles have charging stalls with a layout configured to accommodate single vehicles. Charging facilities having drive-through or elongated charging stalls able to accommodate larger vehicles which are towing an electrified trailer are much scarcer. When attempting to charge a trailer-mounted battery in a charging stall meant for a single vehicle, it may be necessary to unhitch (i.e., decouple) the trailer while in the charging stall so that the passenger vehicle does not block the aisles of a charging station. Sensors in the vehicle perform a sensor sweep of a selected charging stall, and after unhitching, the trailer uses an independent drive system to park itself in the selected charging stall using driving commands which are calculated from the sensor sweep.

An electric moving object guiding situation of wireless charging and a method using the same includes a power reception module unit configured to receive power through a power transmission module unit of a wireless charging device; a charging controller configured to control a charging operation and to generate data associated with information on a charging situation including charging progress information and charging obstacle information that occurs during a charging abnormality; and a processor configured to transmit data associated with the information on the charging situation so that the data is displayed on a user device.

A charging system for autonomous charging of an electric vehicle with electric energy includes a vertical charging arm part, a charging cable or busbar connectible to the electric vehicle, and an elongate horizontal charging arm part extendible from the vertical charging arm part toward the electric vehicle. The horizontal charging arm part has a first drive system with a first linear operative direction corresponding to a longitudinal direction of the horizontal charging arm part, allowing a vehicle-side end of the horizontal charging arm part to move autonomously using the first drive system, relative to the electric vehicle relative to a first linear degree of freedom. A second drive system has a second linear operative direction moving the horizontal charging arm part autonomously relative to the electric vehicle relative to a second linear degree of freedom. A method for charging an electric vehicle using the charging system is also provided.

Disclosed are a robot, a charging station, and a robot charging system comprising same. The charging station of the present disclosure may comprise: at least one indicator; at least one reflector configured to reflect light received from the outside to the at least one indicator; an interface configured to dock an external device; and a processor that, when it is detected that the external device is docked in the interface, supplies power to the docked external device through the interface. In addition, the robot of the present disclosure may comprise: a driver; a sensor; and a processor is configured to, when light irradiated to a charging station by means of a light emitter of the sensor is reflected by at least one indicator of the charging station and then received by a light detector of the sensor, perform alignment for docking on the charging station on the basis of a pattern of the reflected light, and after performing the alignment, control the driver such that the robot may be docked on the charging station.

An alignment method for wireless charging of an electric vehicle includes identifying presence of a wireless power transmission pad during driving, estimating a distance to the wireless power transmission pad, performing a macroscopic alignment procedure according to the distance, and performing wireless charging based on the macroscopic alignment procedure being completed.

A wireless power-transmitting device includes a power-transmitting coil installed in a predefined parking area, a receiving device configured to receive a signal for a power supply instruction transmitted through a windshield or through a rear window of a vehicle, and a control device configured to control supply of electric power from the power-transmitting coil to a power-receiving coil of the vehicle based on the signal received by the receiving device.

A charging amount calculation apparatus calculates an amount of power consumption by a battery for running along a running route and a during-running charging amount received by a power reception apparatus from at least one second power feeding facility. The charging amount calculation apparatus calculates a pre-running charging amount based on the amount of power consumption and the during-running charging amount.

A coil alignment method performed in a vehicle-side coil alignment apparatus coupled to a vehicle assembly (VA) controller includes: moving a light-blocking unit protruding from a vehicle parked in a wireless charging area in a first direction toward the ground facing one side of a vehicle-side wireless power transfer pad which is mounted on the vehicle and includes a VA coil, where the light-blocking unit protrudes from the one side of the vehicle-side wireless power transfer pad; stopping movement of the light-blocking unit in response to a first stop signal from a ground assembly (GA) controller; moving the light-blocking unit in a second direction perpendicular to the first direction; and stopping movement of the light-blocking unit in response to a second stop signal from the GA controller.
