Wireless charging systems with multiple power receiving devices
First Claim
1. An electronic device comprising:
- a coil that is configured to receive wireless power signals;
a display; and
control circuitry operatively coupled to the coil and display, the control circuitry configured to;
receive a first device identifier from a power transmitting device, wherein the first device identifier identifies a first wireless power transmitter;
receive a second device identifier from an external electronic device, wherein the second device identifier identifies a second wireless power transmitter; and
determine whether to present, at the electronic device, a battery charge status of the external electronic device based on the first device identifier and the second device identifier.

Abstract
A wireless charging system may include a wireless power transmitting device that receives multiple wireless power receiving devices. A primary power receiving device that is used to display battery charge status information for other power receiving devices on the power transmitting device may be referred to as a hero device. The other wireless power receiving devices may be referred to as paired devices. When a paired device is added to a wireless power transmitting device where a hero device is already present, the hero device may verify that the paired device is on the same mat as the hero device. The hero device and paired device may then synchronously output a user notification. When a paired device is present on a wireless power transmitting device, the paired device may send battery charge status information to the wireless power transmitting device at predetermined intervals.
