System and method for a multi-coil wireless power transfer
First Claim
1. A wireless charging system comprising:
- a first transmitting coil disposed within a lower portion of a wireless charger;
a second transmitting coil disposed within a side portion of the wireless charger;
a communications module configured to receive a signal from an information handling system, the information handling system including a receiving coil; and
a processor configured to;
determine an orientation of the receiving coil, wherein the receiving coil is not oriented coaxially with the first transmitting coil or the second transmitting coil;
determine a target flux vector based on the orientation of the receiving coil; and
determine a first current to provide to the first transmitting coil and a second current to provide to the second transmitting coil based on the target flux vector.
