1. Non-transitory computer-readable media storing computer-executable instructions that, when executed, perform operations for avoiding inductive charging disruption comprising:
- detecting an event that is predicted to change a voltage supplied to a primary coil, wherein the change in voltage presents an increased likelihood of interrupting a charging function of the primary coil; and
responsive to the event, avoiding interruption of the charging function of the primary coil by shifting a voltage of the primary coil to counteract the predicted change in the voltage supplied to the primary coil due to the event.

Abstract
Maintaining continuous wireless charging of a device includes various elements. Events that may disrupt wireless charging are detected and the disruption circumvented by adjusting functions of an inductive coil. A frequency and power-shifting methodology is employed to achieve the continuous wireless charging. The invention may be implemented into various devices and environments, including vehicle consoles.

11. A method for limiting inductive charging disruption, the method comprising:
-
detecting a signal; measuring a frequency and amplitude of the detected signal; when it is determined that the measured frequency and amplitude of the detected signal will disrupt a charging function of a first coil by causing interference with an operating frequency of the first coil, changing the operating frequency of the first coil to create a margin between the operating frequency of the first coil and the frequency of the detected signal, wherein the operating frequency affects an amount of power inductively supplied from the first coil to a second coil; and when changing the operating frequency of the first coil, maintaining the amount of power inductively supplied from the first coil at a level sufficient to charge a power supply coupled with the second coil. - View Dependent Claims (12, 13, 14, 15)

16. An inductive coupling device for avoiding charging disruption, the device comprising:
-
a primary coil that connects to a power source; and a controller that dictates primary-coil operations and that utilizes a processor to; receive an indication of an event that is predicted to change a voltage supplied by the power source to the primary coil, wherein the change in voltage presents an increased likelihood of interrupting a charging function of the primary coil; and in response to receiving the indication, avoiding the change in the charging function of the primary coil by modifying one or more operating parameters of the primary coil to counteract the predicted change in voltage supplied by the power source to the primary coil, wherein the one or more operating parameters include a voltage supplied from the primary coil to a secondary coil and another voltage supplied to the primary coil from the power source. - View Dependent Claims (17, 18)
