Abstract
A system, method, and apparatus for wirelessly charging a load. A primary transformer coil from an energy source is provided to interface with a load application with a secondary transformer coil. The method of charging is independent of resonance frequency.
Claims27
An electrical charging unit for a wireless transfer of energy, the electrical charging unit comprising:
- one or more first windings mateable with one or more mating windings for the wireless transfer of energy between the one or more first windings and the one or more mating windings;
- a first ferromagnetic core around which the one or more first windings are disposed;
- and wherein:
- the one or more first windings are not conductively coupleable to the one or more mating windings;
- and
- the one or more first windings are not required to be disposed in a plane.
3 more elements
An autonomous electrical charging system comprising:
- a chassis;
- a powertrain coupled to the chassis;
- and
- a brushless dispensing unit coupled to the chassis, the for an electrical cord;
- an electrical charging unit (200) for a wireless transfer (114) of energy, the charging unit further comprising:
- one or more first windings (225) mateable with another winding (234) for wirelessly transferring energy between the one or more first windings and the another winding;
- a first ferromagnetic core (232) around which the one or more first windings are disposed;
- and
- wherein:
- the one or more first windings are not conductively coupleable to the another winding;
- and
- the one or more first windings are not required to be disposed in a plane.
9 more elements
A method of wirelessly transferring energy from an electrical charging unit to a load:
- traversing either the one or more first windings or the one or more mating windings to proximate location with each other;
- coaxially self-aligning an axis of the one or more first windings with an axis of the one or more mating windings;
- and
- longitudinally self-aligning the one or more first windings with the one or more mating windings along approximately coaxially self-aligned axes of the one or more first windings and the one or more mating windings.
