US Patent 11689065 System and methods for charging a device

Systems and methods for supplying power to an electronic device are provided. A first power limit is received from the electronic device at a transmitter. The transmitter input power is set to correspond to the first power limit. The transmitter supplies power corresponding to the transmitter input power to the electronic device to initiate charging, and an electrical value associated with the transmitter input power is monitored. During monitoring, the first electrical value is compared to a predefined second electrical value, the power supply to the receiver is discontinued based on the monitoring, and the transmitter input power is adjusted to correspond to a second power limit based on the comparison.
