  • Autonomous wireless charging system and method based on power loss tracking
    Patent number: 11894697
    Abstract: The present invention relates to an autonomous wireless charging system, and more specifically, to a tray-type case and a high-precision autonomous wireless charging system based on power loss tracking, whereby, in terms of performance, the center position of a power receiving coil of a wireless device having a battery mounted therein, the wireless device being placed on top of a charger pad, is precisely tracked through a controller in the system by periodically tracking a difference in the increase/decrease of a power loss value generated in the process of foreign object detection of a power transmitter, and even when the position of the wireless device shifts, a power transmitting coil mounted in a moving device unit is accurately repositioned to the changed position through threshold value identification or, when necessary, by the selective use of a sensor matrix, thereby enabling the centers of the power transmitting coil and the power receiving coil to always coincide, and thus a maximum level of wirele
