POWER TRANSMITTING DEVICE, POWER RECEIVING DEVICE, AND NON-CONTACT CHARGING METHOD

摘要

In a non-contact charging method, variable information with which a resonance frequency of a resonance circuit of an equipment device having maximum charging power as the power transmitting frequency, and a resonance frequency or a Q value of a resonance circuit of a power receiving unit of an equipment device other than the equipment device having the maximum charging power as a resonance frequency or a Q value for charging depending on each charging power, and transmits to each equipment device variable information corresponding to each equipment device.

主权项

1. A power transmitting device, comprising:
a power transmitting unit which transmits electric power at a power transmitting frequency using magnetic field resonance or electric field resonance to each of a plurality of equipment devices including a non-contact power receiving unit; a control unit which obtains variable information which sets a resonance frequency of a resonance circuit of an equipment device having maximum charging power as the power transmitting frequency, and sets a resonance frequency or a Q value of a resonance circuit of a power receiving unit of an equipment device other than the equipment device having the maximum charging power as a resonance frequency or a Q value for charging depending on each charging power; a power supply unit which provides the power transmitting unit with electric power to be transmitted to the equipment device; and a communication unit which transmits to each equipment device variable information corresponding to each equipment device.
