Abstract
In one embodiment, a device in a wireless power transfer (WPT) system receives data regarding a vehicle equipped with a vehicle-based charging coil configured to receive electrical power transferred from a ground-based charging coil of the WPT system. The device determines, based on the received data, a time at which the vehicle-based charging coil is expected to be in charging proximity of the ground-based coil. Based on the received data, the device determines a gap distance between the vehicle-based charging coil and the ground-based charging coil to optimize the transfer of electrical power from the ground-based charging coil to the vehicle-based charging coil when the coils are in charging proximity of one another. The device sends control instructions to an adjustment system to implement the identified gap distance in advance of the determined time by adjusting a height of the vehicle-based charging coil or the ground-based charging coil.
