Abstract
A power supply apparatus including a near-field wireless communication unit that wirelessly communicates with a plurality of communication terminals, a power transmission unit that sets a plurality of resonance frequencies to transfer power in a non-contact manner to each of the plurality of communication terminals, and a control unit that determines a priority level of each of the communication terminals based on identification information received from the communication terminals and determines an amount of power transmitted at each of the resonance frequencies based on the determined priority levels.
Claims20
A power supply apparatus comprising:
- a near-field wireless communication unit configured to wirelessly communicate with a plurality of communication terminals;
- a power transmission unit configured to set a plurality of resonance frequencies to transfer power in a non-contact manner to each of the plurality of communication terminals;
- and
- a control unit configured to determine a priority level of each of the communication terminals based on identification information received via the near-field wireless communication unit, and determine an amount of power transmitted at each of the resonance frequencies based on the determined priority levels.
A wireless power transmission method performed by a power supply apparatus, the method comprising:
- receiving identification corresponding to each of a plurality of communication terminals via near-field wireless communication;
- setting a plurality of resonance frequencies to transfer power in a non-contact manner to each of the communication terminals;
- determining a priority level of each of the communication terminals based on the received identification information;
- and
- determining an amount of power transmitted at each of the resonance frequencies based on the determined priority levels.
A non-transitory computer readable medium including computer program instructions, which when executed by a power supply apparatus, cause the power supply apparatus to perform a method comprising:
- receiving identification corresponding to each of a plurality of communication terminals via near-field wireless communication;
- setting a plurality of resonance frequencies to transfer power in a non-contact manner to each of the communication terminals;
- determining a priority level of each of the communication terminals based on the received identification information;
- and
- determining an amount of power transmitted at each of the resonance frequencies based on the determined priority levels.
A communication terminal comprising:
- a non-contact power reception unit configured to receive power from a power supply apparatus;
- a near-field wireless communication interface configured to transmit identification data to the power supply apparatus, and receive a response indicating a resonance frequency at which the non-contact power reception unit is to receive power from the power supply apparatus;
- and
- a control unit configured to set a resonance frequency of the non-contact power reception unit to the resonance frequency indicated by the power supply apparatus.
A wireless power reception method performed by a communication terminal, the method comprising:
- transmitting identification data to a power supply apparatus;
- receiving a response indicating a resonance frequency at which a non-contact power reception unit of the communication terminal is to receive power from the power supply apparatus;
- setting a resonance frequency of the non-contact power reception unit to the resonance frequency indicated by the power supply apparatus;
- and
- receiving, at the non-contact power reception unit, power from a power supply apparatus.
