Abstract
A multi-cell inductive wireless power transfer system includes multiple transmitting elements. Each transmitting element includes one or more transmitting windings and one or more transmitting magnetic cores. The multi-cell inductive wireless power transfer system also includes multiple receiving elements. The transmitting elements are separated from the receiving elements by an air gap. Each receiving element includes one or more receiving windings and one or more receiving magnetic cores.
Claims8
A method of controlling a power charging system, the method comprising:
- generating a magnetic field via at least one transmitting element among a plurality of transmitting elements installed in a charging station, the magnetic field generated in response to energizing at least one transmitting winding arranged adjacent to at least one transmitting magnetic core included in the at least one transmitting element;
- and
- positioning a vehicle including at least one receiving element among a plurality of receiving elements in proximity of the magnetic field to energize at least one receiving winding arranged adjacent to at least one receiving magnetic core included in the at least one receiving element;
- generating an output power signal in response to energizing the at least one receiving element via the magnetic field;
- charging a battery of the vehicle based on the output power signal;
- determining, via the transmitting controller and the receiving controller, a first transmitting clock phase of at least one transmitting element and a first receiving clock phase of at least one receiving element;
- identifying an unbalanced phase of the output power signal;
- in response to determining the unbalanced phase, determining a lost phase among at least one of the first transmitting clock phase and the first receiving clock phase;
- identifying at least one of a faulty transmitting element and a faulty receiving element causing the lost phase;
- and
- resetting remaining phases to a new synchronization frequency to restore a phase balance of the output power signal.
