Abstract
Devices, systems, and methods related to wireless charging for transportation vehicles include a wireless charge assembly including a capacitor bank assembly, shielding body, and a coil assembly. The coil assembly can include a coil body having a plurality of shielding turns positioned which can be arranged to reduce stray field from inductive charging of the transportation vehicle.
Claims18
A vehicle capable of wireless charging comprising:
- a transportation vehicle chassis having a lower section;
- and
- a charge assembly mounted with the lower section and configured to receive wireless charge from a ground charge assembly, the charge assembly comprising a shielding body, a capacitor bank assembly arranged on one side of the shielding body, and a charge coil assembly arranged on an opposite side of the shielding body, the charge coil assembly comprising a coil body including a number of coils each having coil turns arranged in a charging plane, wherein the coil body includes a plurality of shielding turns positioned along the charging plane adjacent the number of coil turns, wherein the shielding turns are arranged on opposing ends of the coil body within the charging plane,
- wherein ends of the number of coils penetrate through the shielding body at the same location to reduce additional flux and/or stray field, wherein the location of penetration through the shielding body corresponds with a center of one of the coils.
