Appl. No.:

16/277695

Inventors:

- Salt Lake City UT, US
RYAN CALDER - Saratoga Springs UT, US
EVANS GRIEGO - Murray UT, US
STEVE BALL - Sandy UT, US

International Classification:

H02J 50/12
H01F 27/28
H02J 50/40

Abstract:

A vault apparatus for wireless power transfer includes a vault comprising an opening for a wireless power transfer (“WPT”) pad. The opening is located on a top of the vault. The vault apparatus includes a junction box formed into the vault. The junction box includes an opening oriented toward the top of the vault. The vault apparatus includes a sealing ring that maintains a WPT pad fixed in the vault where a portion of the sealing ring covers the junction box.

Abstract:

An approach module determines that a wireless power transfer (“WPT”) secondary pad on a vehicle approaching a WPT primary pad is within an approach distance threshold from the primary pad. A pulse module generates an electrical alignment pulse in the primary or secondary pad in response to determining that the secondary pad is within the approach distance. A measurement module determines an amount of magnetic coupling between the primary pad and the secondary pad, and a feedback module that provides an alignment signal to a driver of the vehicle. The alignment signal represents magnetic coupling. The pulse module continues to provide electrical alignment pulses, the measurement module continues to determine an amount of magnetic coupling in response to the electrical alignment pulses, and the feedback module continues to provide alignment signals indicative of an amount of magnetic coupling as the vehicle moves in relation to the primary pad.
