A server includes a processor and a communication device configured to acquire a transmitted power amount transmitted from a power facility during external charging of a vehicle participating in a DR. The processor is configured to calculate, when a plurality of vehicles participates in the DR, a standard reward that is a standard of a reward given from an aggregator to each of the vehicles, according to the transmitted power amount, decide, when a first vehicle participates in the DR, a first reward that is a reward given from the aggregator to the first vehicle, such that the first reward becomes the standard reward for the first vehicle, and decide, when a second vehicle participates in the DR, a second reward that is a reward given from the aggregator to the second vehicle, such that the second reward becomes higher than the standard reward for the second vehicle.

Described herein are methods and system for pairing a wireless power receiver to a wireless power transmitter. The method can include joining, by the wireless power receiver, to a wireless network provided by a network device and transmitting, by the wireless power receiver over the wireless network, a message to a primary wireless power transmitter. The method can include receiving, by the wireless power receiver from the primary wireless power transmitter, identification information of an available communication channel and an SSID associated with an available transmitter. The method can include receiving, by the wireless power receiver over the wireless network, alignment information from the available transmitter associated with the SSID, detecting that the vehicle has parked proximate to the available wireless power transmitter according to the alignment information, and establishing, by the wireless power receiver with the available transmitter, a connection based on the SSID.

A management system used in a charging facility for performing non-contact charge to electric vehicles running in a charge zone includes a control apparatus including a processor and a memory and configured to select one or more charge permitted vehicles for which charge is permitted from an electric vehicle group including electric vehicles running in a determination area including at least part of the charge zone. The control apparatus is configured to calculate an upper-limit number of the charge permitted vehicles based on a target vehicle speed indicated to the charge permitted vehicles, to order the electric vehicles in the electric vehicle group in an ascending order of mileages based on the mileage of each electric vehicle composing the electric vehicle group, and to select the charge permitted vehicle from the electric vehicle group based on a result of ordering the electric vehicles and the upper-limit number.

An urban air mobility power supply system includes an urban air mobility (UAM) device and a power supply drone docked with the UAM device using electromagnetic force to supply external power, and a power supply method, in which the UAM device 200 and the power supply drone are accurately aligned with each other using electromagnets provided in the UAM device and the power supply drone to supply power, and the UAM device and the power supply drone can be easily separated from each other using electromagnetic force.

In an embodiment, an apparatus for charging an electric vehicle, can include a receptacle mountable to a structure above the electric vehicle. The receptacle can maintain a charge transmitting device, which can be automatically moveable and directable from the receptacle toward a target area on the electric vehicle associated with a receiving coil mounted on the electric vehicle for the charging of an electric vehicle when the one receiving coil engages with the charge transmitting device when the electric vehicle is located below the receptacle. One or more optical sensors can be utilized to direct the charge transmitting device toward the target.
