Each of the charging bays comprises an antenna configured to provide charging power to a battery disposed in a receptacle. The charging device includes a charging controller to provide charging power to the battery via the antenna.

The present specification relates to a device and method for supporting heterogeneous communication in a wireless power transfer system. The present specification discloses a wireless power reception device comprising: a power pickup circuit configured to receive, from a wireless power transfer device, wireless power generated on the basis of magnetic coupling in a power transfer phase; and a communication and control circuit configured to transmit, to the wireless power transfer device, a first random address packet including a random address of the wireless power reception device or receive, from the wireless power transfer device, a second random address packet including a random address of the wireless power transfer device via in-band communication. By performing a handover using a random address, cross reference can be prevented and security can be enhanced, and thus a BLE connection in a wireless charging system can be more safely performed.

One or more disclosed embodiments relate to a wireless charging transmitter and a wireless power transfer method. The wireless charging transmitter includes a first charging pad including a first wireless power circuit, a second charging pad including a second wireless power circuit, and a controller configured to, in response to detection of a first electronic device being placed on the first charging pad, transfer power at a first designated wireless power level via the first wireless power circuit, in response to detection of a second electronic device being placed on the second charging pad, transmit a first command for decreasing power transferred to the first electronic device, and transfer, upon receipt of a first request for power at a second designated wireless power level from the first electronic device in response to the first command, the power at the second designated wireless power level via the first and second wireless power circuits. The disclosure may further include other various embodiments.

After a data backup unit connects to a mobile device, an App executed on the mobile device will create a user profile block in the memory unit of the data backup unit, help set up charging preferences and backup preferences in the profile block, and create a backup folder to store backup files from the mobile device. The App estimates a charging time required to charge the battery, a backup time required to complete the data backup and an available time interval, then the App sums up the charging time and the backup time to get a required time interval. Then, the App compares the required time interval and the available time interval to decide whether to perform both the backup task and the charging task or to perform just the charging task.

A control device includes a first acquisition unit configured to acquire geographical position information of a battery registered as being mounted in an electric power supply target, a second acquisition unit configured to acquire geographical position information of the electric power supply target having the battery mounted therein, a determination unit configured to determine whether a change has occurred in a relative relationship between the geographical position information of the battery acquired by the first acquisition unit and the geographical position information of the electric power supply target acquired by the second acquisition unit, and a coping unit configured to stop supply of power to the electric power supply target having the battery mounted therein in a case where it is determined by the determination unit that a change has occurred in the relative relationship.

An inductive charging system for inductive charging of electronic devices is disclosed. In accordance with an embodiment, the system includes a substantially planar inductive charging coil parallel to the surface of the inductive charger or the electronic device. The system further includes a metallic layer positioned proximate to and substantially parallel to the inductive coil to cover a surface of the inductive coil. The metallic layer comprises multiple substantially concentric rings or polygons, with each of the concentric rings or polygons having multiple sections separated by gaps such that each concentric ring or polygon is discontinuous. Adjacent sections of each concentric ring or polygon are electrically isolated from one another to avoid eddy current generation and heating of the metallic layer during inductive power transfer.
