Abstract
A charging pad includes a housing, an interface layer, a magnetics assembly, and an electronics assembly. The housing has a magnetics assembly housing part and an electronics assembly housing part. The interface layer is within the housing. The magnetics assembly is arranged below the interface layer within the magnetics assembly housing part and the electronics assembly is arranged above the interface layer within the electronics assembly housing part.
Claims15
A charging pad comprising:
- a housing having a magnetics assembly housing part and an electronics assembly housing part;
- an interface layer within the housing, the interface layer having a top side and a bottom side, wherein the interface layer includes a thermal insulator sub-layer and an electromagnetic shielding sub-layer, the thermal insulator sub-layer forms one of the top side and the bottom side of the interface layer and the electromagnetic shielding sub-layer forms an other one of the top side and bottom side of the interface layer;
- wherein the magnetics assembly housing part includes a floor portion spaced apart from the bottom side of the interface layer;
- wherein the electronics assembly housing part includes a ceiling portion spaced apart from the top side of the interface layer;
- a magnetics assembly arranged below the bottom side of the interface layer within the magnetics assembly housing part and attached to the floor portion of the magnetics assembly housing part;
- and
- an electronics assembly spaced apart from and arranged above the top side of the interface layer within the electronics assembly housing part and attached to the ceiling portion of the electronics assembly housing part, the electronics assembly including a printed circuit board having electric and electronic components arranged thereon, the printed circuit board being attached to the ceiling portion of the electronics assembly housing part.

A charging pad for an electric vehicle, comprising:
- a magnetics assembly to wirelessly receive power from a charging source;
- an electronics assembly to convert the power wirelessly received by the magnetics assembly into electrical power for charging the electric vehicle;
- an interface layer separating the magnetics assembly and the electronics assembly, the interface layer includes a thermal insulator sub-layer and an electromagnetic shielding sub-layer;
- a magnetics assembly housing part having a floor portion spaced apart from the interface layer;
- an electronics assembly housing part having a ceiling portion spaced apart from the interface layer;
- wherein the magnetics assembly is arranged below the bottom side of the interface layer within the magnetics assembly housing part and is attached to the floor portion of the magnetics assembly housing part whereby heat generated by the magnetic assembly thermally conducts from the floor portion of the magnetics assembly housing part into an external environment;
- and
- wherein the electronics assembly is spaced apart from and arranged above the top side of the interface layer within the electronics assembly housing part and is attached to the ceiling portion of the electronics assembly housing part whereby heat generated by the electronics assembly thermally conducts from the ceiling portion of the electronics assembly housing part into the external environment, the electronics assembly including a printed circuit board having electric and electronic components arranged thereon, the printed circuit board being attached to the ceiling portion of the electronics assembly housing part.
