A power receiving apparatus includes a power receiving unit and a control unit. The power receiving unit receives a first power from a power supply apparatus via a connection unit. The control unit determines whether or not authentication information including identification information of the power supply apparatus is authentic, and determines whether or not the power supply apparatus has passed a compliance test based on the identification information. The power receiving unit is allowed to receive a second power greater than the first power, in a case where the authentication information is authentic and the power supply apparatus has passed the compliance test.

Various embodiments include a storage device for electrical energy, the device comprising: a rechargeable battery; two terminals to connect the battery to at least one of: a supply network, an electrical load, and/or an electrical generator; a control unit to control charging and discharging of the battery; a communication interface configured to provide wireless data access; and a display of machine-readable code including authentication data enabling wireless data access.

An authentication between a wireless charger and a device configured to receive wireless energy from the wireless charger includes establishing a wireless data channel between the wireless charger and the device. An authentication challenge signal is driven onto a transmit charging coil of the wireless charger and a receive charging coil of the device is configured to receive the authentication challenge signal. The device sends an authentication response signal to the wireless charger based at least in part on the authentication challenge signal.

Described herein is a battery system that allows a battery pack to operate in different modes at different times. Each of the different modes may provide its own set of functionality that affects how the battery pack operates and/or reacts to external input signals. A mode may change how the battery pack discharges power by, for example, altering whether terminals are enabled or disabled. A mode may change how the battery pack's hardware operates by, for example, disabling or enabling portions of the battery pack's hardware. A mode may change what battery-related services are provided by the battery pack and available to an end user by, for example, enabling or disabling the sending of battery status information from the battery pack.

An apparatus and a method for an aerosol generating device is described, the apparatus including a charging controller. The charging controller is configured to control charging of a battery using a power supply at a charging current dependent, at least in part, on power capabilities of the power supply.

A vehicle is a vehicle in which a mounted power storage is charged with electric power from a charging facility, the vehicle including a communication unit that obtains a first voltage value indicating an outputtable voltage value that can be outputted from the charging facility and a processing unit that transmits to the charging facility, a third voltage value which is equal to or smaller than the first voltage value as a maximum voltage of the power storage when a second voltage value indicating a maximum voltage value of the power storage is larger than the first voltage value.

An electronic device according to various embodiments of the present invention may comprise: a connector comprising at least one power terminal for receiving power supplied from an external electronic device, and at least one data terminal for transmitting/receiving data to/from the external electronic device; and a processor comprising at least one sensing terminal connected to the at least one data terminal through at least one resistor, wherein the processor is configured to: when the external electronic device is connected to the electronic device through the connector, check a value corresponding to the voltage at the at least one data terminal, by using the at least one sensing terminal; and transmit, to the external electronic device, a control signal for controlling power supply from the external electronic device, on the basis of the value checked by means of the at least one sensing terminal. The various embodiments of the present invention may also include other embodiments.

Systems and methods are provided for charging for a connection in a radiocommunication system that provides services to both a device which is directly connected to the radiocommunication system and one or more other devices which connect to the radiocommunication system using, e.g., the transceiver of the device which is able to directly connect to the radiocommunication system. A method for charging for a first device which is connected to a second device that has radiocommunication connectivity includes receiving, at a node in the radiocommunication system, a charging authorization message for the second device’s connection to the radiocommunication system, which charging authorization message includes the device identifier associated with the first device; adding, by the node in the radiocommunication system, the device identifier for the first device to a list associated with the second device; and sending an indication that a connection for the first and second device is authorized.

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 charging management unit of a charging management server acquires contact information of a first user who uses a charging unit for charging a traction battery of a vehicle. The charging management unit of the charging management server receives a first request indicating that a second user, who is a user different from the first user, wants to use the charging unit being used by the first user after the first user has finished using the charging unit. When the charging management unit of the charging management server receives the first request, it notifies the first user about the first request.
