Abstract
Magnetic or electromagnetic field generators are disposed on, near or toward opposite sides of a roadway, carriageway or lane such that magnetic or electromagnetic lines of force across at least a portion of the roadway, carriageway or lane. A vehicle traveling down the roadway, carriageway or lane interacts with the magnetic or electromagnetic lines of force to absorb energy that can be used for battery recharging or other purposes. Magnetic or electromagnetic flux density can be increased by embedding magnetic materials or additional structures in the top paving course forming the roadway, carriageway or lane.
Claims20
A charging roadway for wirelessly charging vehicles as they move along a carriageway or lane longitudinal path, the carriageway or lane having a transverse extent between a first side of the carriageway or lane and a second side of the carriageway or lane opposite the first side, the transverse extent being sufficiently wide to accommodate the vehicles as they travel along the longitudinal path, the charging roadway comprising:
- a first array of electromagnets disposed on or in the first side of the carriageway or lane, the first array of electromagnets providing a first series of magnetic poles;
- and
- a second array of electromagnets disposed on or in the second side of the carriageway or lane opposite the first side and spaced apart from the first array of electromagnets with the longitudinal path between the first array of electromagnets and the second array of electromagnets, the second array of electromagnets providing a second series of magnetic poles,
- the first array of electromagnets and the second array of electromagnets configured to cooperatively produce charging magnetic fields spanning between the first series of magnetic poles and the second series of magnetic poles, without requiring registry of magnetic field pickup elements on vehicles moving along the roadway with either the first array of electromagnets or the second array of electromagnets for wireless charging.
A charging roadway including a carriageway or lane disposed on a top surface course, the carriageway or lane providing a path for longitudinal vehicle travel down the roadway, the charging roadway comprising:
- a first electromagnet disposed in or on the top surface course on a first side of the carriageway or lane,
- a second electromagnet disposed in or on the top surface course on a second side of the carriageway or lane opposite the first side, the path being defined between the first side and the second side,
- the first electromagnet and the second electromagnet cooperating to produce a charging magnetic field spanning the path from the first side of the carriageway or lane to the second side of the carriageway or lane;
- and
- ferromagnetic particles disposed within the top surface course between the first side of the carriageway or lane and the second side of the carriageway or lane, the ferromagnetic particles providing a magnetic characteristic that causes or encourages the charging magnetic field to span the path between the first side of the carriageway or lane and the second side of the carriageway or lane so that neither the first electromagnet nor the second electromagnet are disposed underneath vehicles traveling down the roadway.
A charging roadway for wirelessly charging vehicles as they move along a longitudinal path on the charging roadway, the charging roadway having a transverse extent that is sufficiently wide to accommodate the charging vehicles as they move along the longitudinal path, the charging roadway comprising:
- a first array of electromagnets disposed on or in a first side of the transverse extent, the first array of electromagnets providing a first series of magnetic poles;
- and
- a second array of electromagnets disposed on or in a second side of the transverse extent opposite the first side and spaced apart from the first array of electromagnets with the longitudinal path between the first array of electromagnets and the second array of electromagnets, the second array of electromagnets providing a second series of magnetic poles,
- the first array of electromagnets and the second array of electromagnets configured to cooperatively produce charging magnetic fields spanning across the transverse extent between the first series of magnetic poles and the second series of magnetic poles, without either the first array of electromagnets or the second array of electromagnets being aligned beneath wireless charging magnetic field pickup elements on charging vehicles moving along the longitudinal path.
