In one embodiment, a device may include a processor, memory, at least one speaker coil configured to reproduce audio signals and receive wireless power from a wireless power source, and a switch configured to switch the at least one speaker coil between reproducing the audio signals and receiving the wireless power from the wireless power source. A method may include identifying a device that includes at least one speaker coil, receiving, via the at least one speaker coil, audio signals, and receiving, via the at least one speaker coil, wireless power. Various other methods, systems, and computer-readable media are also disclosed.

A system and method for a recharging station including an elevated landing pad, a rechargeable component coupled to the elevated landing pad, a power delivery unit configured to deliver power from a power supply unit or power storage unit to the recharging component, and a support component coupled to the bottom of the elevated landing pad.

A vehicle configured to be able to suitably judge whether to be supplied with power by noncontact while running, that is, a vehicle configured to receive power from a ground power supplying apparatus by noncontact, comprising a control device for controlling reception of power from the ground power supplying apparatus while running based on charging scheduled after the vehicle finishes running.

Electric vehicle charging management methods and systems are provided. A server performs a charging scheduling operation for each electric vehicle charging station to determine a specific time point for each electric vehicle charging station to perform a charging operation in which the charging operation is to charge an electric vehicle coupled with the electric vehicle charging station. When the charging operation corresponding to each electric vehicle charging station is being performed, each electric vehicle charging station transmits charging information corresponding to the charging operation to the server through a network. The server determines whether the charging operation of specific electric vehicle charging station among the electric vehicle charging stations is abnormal based on the charging information received from each electric vehicle charging station, and generates a warning notification and sends the warning notification through the network when the charging operation of the specific electric vehicle charging station is abnormal.

A battery charger includes a housing having support structure for simultaneously supporting at least two batteries of different types for charging including a first battery of a first type and a second batter of a second type. The battery charger further includes charger electronics supported by the housing and operable to output charging current to charge the first battery and charging current to charge the second battery. A fan is operable to cause air flow through the housing. A fan speed of the fan is adjustable based on a temperature of the battery charger (i) while at least one of the at least two batteries is coupled to the battery charger for charging and (ii) while no batteries are coupled to the battery charger for charging.

An electronic device includes a charging unit that charges a battery with power supplied from an external device, and a control unit that controls a communication unit of the electronic device such that a communication interval from a start of charging the battery by the charging unit until a battery voltage exceeds a predetermined threshold is shorter than a communication interval after the battery voltage exceeds the predetermined threshold, in a case where power is received from the external device.
