Abstract
The present invention relates to a wireless power transmission or reception system for measuring a valid charging time in which a voltage value measured by a reception unit is equal to or greater than a pre-configured voltage value, and controlling transmission power so that the valid charging time is included in a pre-configured target charging time range.
Claims19
A magnetic resonance wireless power transmission and reception system comprising a transmitter Tx installed on one side of a device and a receiver Rx installed on the other side and intermittently charged by an operation of the device,
- wherein a valid charging time during which a voltage value measured by the receiver is greater than or equal to a preset voltage value is measured, and transmission power is controlled so that the valid charging time is within a preset target charging time range.
A magnetic resonance wireless power transmission and reception system comprising a transmitter Tx installed on one side of a device and a receiver Rx installed on the other side and intermittently charged by an operation of the device,
- wherein a valid charging time during which a voltage value measured by the receiver is greater than or equal to a preset voltage value is measured, and transmission power is controlled so that a charging section length calculated based on the measured valid charging time is within a preset target charging section length range.
A magnetic resonance wireless power transmission and reception method using charging section control, the method using a magnetic resonance wireless power transmission and reception system comprising a transmitter Tx installed on one side of a device and a receiver Rx installed on the other side and intermittently charged by an operation of the device, the method comprising:
- a step (a) of measuring, by the receiver, a voltage value of the receiver for wireless power transmitted by the transmitter;
- a step (b) of measuring, by the receiver, a valid charging time, which is a time when the measured voltage value of the receiver is greater than or equal to a valid charging voltage value;
- and
- a step (c) of controlling, by the transmitter, transmission power so that the measured charging time received from the receiver is within a preset target charging time range.
A magnetic resonance wireless power transmission and reception method using charging section control, the method using a magnetic resonance wireless power transmission and reception system comprising a transmitter Tx installed on one side of a device and a receiver Rx installed on the other side and intermittently charged by an operation of the device, the method comprising:
- a step (a) of measuring, by the receiver, a voltage value of the receiver for wireless power transmitted by the transmitter;
- a step (b) of calculating a charging section length corresponding to a rotation length of the tire during a charging section according to the measured voltage value of the receiver;
- and
- a step (c) of controlling, by the transmitter, transmission power so that the measured charging section length received from the receiver is within a preset target charging section length range.
