Abstract

An electric vehicle charging apparatus is disclosed. The electric vehicle charging apparatus has a housing having a front cavity, rear cavity, and a separating wall having a common electrical passage, wherein the rear cavity is formed by sidewalls with one sidewall having a slot formed therein. A power cord passes through the common electrical passage in the separating wall, and the power cord is configurable to provide a number of electrical connection options, such as an “outside cord option” and a “rear mount option.” Methods of configuring the electric vehicle charging apparatus are provided, as are other aspects.

Claims

1. An electric vehicle charging apparatus, comprising:

a housing having a body having a front cavity having at least one electrical terminal, a rear cavity formed by sidewalls, at least one sidewall having a slot formed therein, a separating wall separating the front cavity and rear cavity and having a common electrical passage through the separating wall; and

a power cord having a cord length, the power cord connected through the common electrical passage, wherein the cord length is configurable to provide one installation option selected from a group consisting of;

an outside cord option wherein a portion of the cord length extends through the slot to a position outside of a footprint of the body and is adapted to electrically connect to an first electrical article located outside of the footprint, and

a rear mount option wherein a portion of the cord length is received in the rear cavity and is adapted to electrically connect to a second electrical article located inside of the footprint of the body.

2. The electric vehicle charging apparatus of claim 1, wherein the first electrical article is selected from a group of an load center panel, a sub-panel, a gang box, and an electrical receptacle.

3. The electric vehicle charging apparatus of claim 1, wherein the second electrical article is selected from a group of a gang box and an electrical receptacle.

4. The electric vehicle charging apparatus of claim 1, comprising an electrical plug attached to the cord length.

5. The electric vehicle charging apparatus of claim 4, comprising:

the outside cord option wherein a first portion of the cord length extends through the rear cavity, through the slot, and the electrical plug is adapted to electrically connect to an electrical receptacle located outside of the footprint of the body.

6. The electric vehicle charging apparatus of claim 4, comprising:

the rear mount option wherein the cord length and the electrical plug are received in the rear cavity and are adapted to electrically connect to an electrical receptacle located inside of the footprint of the body.

7. The electric vehicle charging apparatus of claim 1, wherein the slot is positioned on a bottom sidewall of the body.

8. The electric vehicle charging apparatus of claim 7, wherein the slot is positioned adjacent to an exit through the lower sidewall of a charging cable.

9. The electric vehicle charging apparatus of claim 1, wherein the rear cavity includes dividing walls positioned on each side of a charging cable that is adapted to electrically connect to an electric vehicle.

10. The electric vehicle charging apparatus of claim 9, wherein a second portion of the cord length passing around the charging cable in the rear cavity is spaced from charging cable the by the dividing walls.

11. The electric vehicle charging apparatus of claim 1, wherein the common electrical passage includes an electrical connector.

12. The electric vehicle charging apparatus of claim 11, wherein the electrical connector comprises a sealed connector.

13. An electric vehicle charging apparatus, comprising:

a housing having a body with a front cavity, a rear cavity formed by sidewalls, wherein at least one of the sidewalls has a slot through, a separating wall separating the front cavity having a common electrical passage, an electrical terminal in the front cavity;

a common electrical pass through connector received in the common electrical passage; and

a power cord having a cord length and an electrical plug at a terminal end, the power cord connected through the common electrical pass-through connector and electrically connected to the electrical terminal in the front cavity, wherein the cord length and electrical plug are configurable to provide a plurality of electrical installation options, selected from a group consisting of;

an outside cord option wherein a portion of the cord length passes through the slot and the electrical plug is configured and adapted to electrically connect to an electrical receptacle located outside a footprint of the body, and

a rear mount option wherein the cord length and electrical plug are received in the rear cavity and are configured and adapted to electrically connect to an electrical receptacle located inside of the footprint of the body.

14. A method of configuring an electric vehicle charging apparatus, comprising:

providing a housing having a body with a front cavity, a rear cavity formed by sidewalls, at least one sidewall having a slot formed therein, a separating wall separating the front cavity and rear cavity and having a common electrical passage through the separating wall, at least one electrical terminal in the front cavity, and a power cord having a cord length, the power cord connected through the common electrical passage; and

configuring the cord length to provide an electrical installation option, selected from a group consisting of;

an outside cord option wherein a portion of the cord length extends through the slot to a position outside of a footprint of the body and is configured to electrically connect to an first electrical article located outside of the footprint, and

a rear mount option wherein the cord length is received in the rear cavity and is configured to electrically connect to a second electrical article located inside of the footprint of the body.

15. The method of claim 14, comprising:

the outside cord option wherein the cord length and coupled electrical plug are configured to electrically connect to an electrical receptacle located outside of the footprint of the body.

16. The method of claim 14, comprising:

the rear mount option wherein the cord length and a coupled electrical plug are received in the rear cavity and are configured to electrically connect to an electrical receptacle located inside of the footprint of the body.
