METHOD FOR CONTROLLING POWER TRANSMISSION IN WIRELESS POWER TRANSMISSION APPARATUS AND WIRELESS POWER TRANSMISSION APPARATUS THEREOF
First Claim
1. A method for controlling a power transmission in a wireless power transmission apparatus, the method comprising:
- detecting via an object detecting sensor whether a foreign object is placed on or near a charging position of the wireless power transmission apparatus during a wireless charging;
calculating a power loss of the wireless charging by a controller of the wireless power transmission apparatus if the foreign object is detected by the object detecting sensor; and
stopping the wireless charging if the power loss is over a reference value.
