A server includes a communication device and a processor. The communication device obtains a power rate unit price dependent on a region where external charging is performed and a time slot when external charging is performed. The processor calculates a first power rate indicating a power rate when the external charging is performed with a first power feeding facility provided at a departure place before departure of a vehicle, calculates a second power rate indicating a power rate when the external charging is performed with a second power feeding facility provided in the vicinity of a traveling route after departure of the vehicle, and when the second power rate is lower than the first power rate, reduces an amount of power feeding during the external charging with the first power feeding facility, as compared with when the second power rate is equal to or higher than the first power rate.

A charging device for inductive transfer of electric energy with a primary conductor arranged in a first housing, by which an alternating magnetic field can be generated when it is energized with an alternating current, electrically connected to a power source that is electrically connectable to a power electronics device for energizing the primary conductor with an alternating current. A drive means for moving the first housing from a first position to a second position, wherein the charging device is equipped with a fault detecting device, by which can be detected whether the first housing is or is not moved when a movement operation has been initiated by the drive means.

A wireless power transfer (WPT) method based on a state of an auxiliary battery and an electric vehicle (EV) for the same includes receiving, by an EV charging apparatus, a wireless jump start request message from a user terminal; transmitting, by the EV charging apparatus, a primary jump start power according to the wireless jump start request message to the EV; driving an auxiliary power supply device provided in the EV by a secondary jump start power induced by the primary jump start power; driving a controller of the EV based on a preset power outputted from the auxiliary power supply device; and charging, by the controller of the EV, an auxiliary battery of the EV.

A charging status or a location of a wireless charger is provided. A vehicle may charge at a particular wireless charger based at least in part on the charging status of the wireless charger and/or the location of the wireless charger.

A vehicle is provided that comprises two or more radio frequency (RF) antennas and two or more RF transceivers to communicate wirelessly sensitive information associated with a user of the vehicle (the two or more RF antennas being at different physical locations on an exterior of the vehicle). The vehicle determines which one of the two or more RF antennas is receiving a strongest signal from a common signal source, selects a first RF transceiver associated with the RF antenna with the strongest signal to send the sensitive information associated with the user to the common signal source, and sends the sensitive information associated with the user to the first RF transceiver for transmission to the common signal source.

A method for producing an inductive charging device may include inserting a ferrite and a coil, wound from a braid, into a mould; and encasing the ferrite and the braid at least partially with a plastic in a low pressure casting method, a pressing transfer moulding method, or an injection moulding method.

A wireless charging system includes a platform having a substantially horizontal upper surface configured to support a vehicle and an induction coil coupled to the platform. The induction coil is configured to receive electrical energy from an energy source and generate a magnetic field above the upper surface, the magnetic field being positioned to wirelessly transfer the electrical energy to the vehicle while the vehicle is positioned atop the platform.
