Glowing J1772 socket

3D Printed Charging Port Lets Your Eco-Credentials Glow

We’re not sure about you, but we find that when trying to find a charging station, locating it can be an utter pain. Even once you’ve found the approximate location of your car’s next refill with your satellite navigation or online map, locating the charging station within that parking lot can take forever, especially at night.

But what if the charging station — specifically the plug and socket — glowed in the dark? Wouldn’t that make it easier to find?

Enter enterprising Canadian EV owner Joel Clemens. As well as being an EV advocate and regular on the DIYelectriccar forum, Clemens happens to own a  3D printer, and set out to make plugging in at night easier by designing and printing glow in the dark Type 1 (J1772) connectors.

While they can’t be used to replace the inlet on your vehicle, these ‘dummy’ connectors can be attached to a wall to hold the J1772 plug found on domestic and public charging stations throughout the world when not in use. As well as being functional, they also help draw your attention to the charging station.

As with many items in the 3D printing community you can download and print this out yourself – staying within the stated licence of course. But for those of you who don’t have access to a 3D printer or glow in the dark material, you can buy this directly from Clemens for $25 plus shipping.

He writes, ‘This is useful as a parking spot marker for your EVSE that will glow in the dark and make it easy to find the J1772 connector in a dark garage or if your charger is outside.It will also act as a cap and protect the plug from bugs and dirt that might get in your plug. Simply mount this plastic part on a wall, post, or even on your existing EVSE. (Screws not included)

‘I am developing other things such as a microEVSE, j1772 splitter/extension and more. Please support my efforts and I will be able to better support the EV community in return.’

At Transport Evolved we believe one of the most powerful aspects of the plug-in community is our ability to modify, adapt and upgrade what we have. These plugs would make a great addition to public charging stations; the could allow a user to quickly see and identify the type of connector from a distance.

What do you think of this project? Do you want a glow in the dark plug? Would it make a good Christmas present? Let us know in the comments below.

    My Hymotion Prius just has a plain black 120V charging port on it, which is hard to find in the dark. To solve that, I simply use an extension cord that has a power indicator light built into the end. That light is bright enough to help me plug the car in.
