Systems and methods for improving misalignment during wireless charging

Abstract

Systems and methods are provided for improving misalignment during wireless charging (e.g., during wireless charging of electric vehicles (EVs)). A transmitter coil can be disposed on a mobile plate, which can act as a robot to move the transmitter. A magnetic field sensor can be installed on the transmitter pad to measure the magnetic field, and the measured magnetic field can be compared with the highest magnetic field value, with the error being sent to a controller. The controller can send a command to the robot to move the transmitter to adjust itself to be better aligned with the receiver. This can continue until the transmitter and the receiver are in a well-aligned state.
