CHARGING VOLATAGE CONFIGURING METHOD FOR WIRELESS CHARGING AND WIRELESS POWER RECEPTION UNIT
First Claim
1. A method for charging voltage configuration of wireless charging by a wireless Power Reception Unit (PRU) which receives wireless charging power from a wireless Power Transmission Unit (PTU), the method comprising:
- measuring charging power received from the wireless power reception unit;
when the measured charging power is smaller than a minimum power level for charging initiation or a difference between the measured charging power and the minimum power level is within a predetermined range, determining a voltage configuration value upwardly adjusted by a pre-configured level in comparison with a pre-configured voltage configuration value; and
transmitting the determined voltage configuration value to the wireless power transmission unit.
