METHOD FOR WIRELESS CHARGING AND DEVICE SUPPORTING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18098354 titled 'METHOD FOR WIRELESS CHARGING AND DEVICE SUPPORTING SAME
Simplified Explanation
The patent application describes a power transmitting unit (PTU) that supports both resonance wireless charging and induction wireless charging. The PTU includes a first coil for induction charging, a second coil for resonance charging, a wireless charging circuit, a short-range wireless communication circuit, and at least one processor.
- The PTU is capable of detecting external electronic devices through its coils and receiving feedback from them.
- Based on the feedback received, the PTU can control the wireless charging circuit to transmit power in a resonance scheme to charge the external electronic device.
- The PTU can also identify if a flat region corresponding to the first coil is available and determine whether to switch the charging scheme from resonance to induction.
- If the flat region is available, the PTU can transmit a control signal through the short-range wireless communication circuit to charge the external electronic device using the induction scheme.
Potential Applications
- Wireless charging systems for electronic devices such as smartphones, tablets, and wearables.
- Charging stations in public places like airports, cafes, and offices.
- Integration into furniture or vehicles to provide convenient charging options.
Problems Solved
- Simplifies the wireless charging process by supporting both resonance and induction charging schemes.
- Allows for efficient charging by dynamically switching between resonance and induction based on the availability of a flat charging surface.
- Provides flexibility in charging options for different types of electronic devices.
Benefits
- Enhanced user experience with the ability to charge devices wirelessly.
- Increased charging efficiency by utilizing the most suitable charging scheme.
- Versatility in charging options for various electronic devices.
Original Abstract Submitted
A power transmitting unit (PTU) configured to support resonance wireless charging and induction wireless charging may include: a first coil for induction wireless charging, a second coil for resonance wireless charging, a wireless charging circuit electrically connected to the first coil and the second coil, a short-range wireless communication circuit, and at least one processor operatively connected to the wireless charging circuit and the short-range wireless communication circuit. The at least one processor may be configured to control the PTU to transmit a first signal for detecting at least one external electronic device through at least one of the first coil and the second coil, and receive, through the second coil, a feedback of the transmitted first signal from a first external electronic device among the at least one external electronic device, and in response to receiving the feedback, control the wireless charging circuit and transmit a first power for charging the first external electronic device in a resonance scheme, and identify whether a first region corresponding to the first coil and being at least partially flat is available, and based on the first region being available, determine whether to change a charging scheme of the first external electronic device from the resonance scheme to an induction scheme, and in response to determining to change the charging scheme of the first external electronic device into the induction scheme, transmit a control signal for charging using the induction scheme to the first external electronic device through the short-range wireless communication circuit.
