ᐅ Underground parking space: Optimal location for a 230V outlet and electric vehicle charging station (wallbox)

Hello everyone,

We have purchased an apartment with an underground parking space and are planning to install a standard 230V outlet at the parking spot as well as a 400V high-voltage line in preparation for a wallbox (for charging an electric car sometime in the future). The parking space is 3m (10 feet) wide.

We need some advice on the best positioning of the outlet and the wallbox. Currently, we plan to place the 230V outlet at the front right of the parking space (green dot) and the wallbox at the back left of the parking space (blue dot).

Does this make sense from your point of view, or would it be better to position the wallbox on the short wall where the green dot is?

Thank you very much for your help!

Good question. Unfortunately, we don’t know the size of the parking space, which would make it easier to say.
However, I would prefer limiting the length rather than the width. So, wallbox plus socket at the green dot. But it also depends on where the car’s charging port is located...
Please remember that the electricity goes through your own meter since this is a condominium association (HOA).

Personally, I wouldn’t worry about that too much, since these aren’t distances you need to cover with a standard outlet. It’s more about, for example, vacuuming the car, right? A 10m (33 feet) extension cord costs about 5€. As for the wallbox, the cable for the electric vehicle is also usually quite long. The position is hard to fix because the charging port on the car isn’t always in the same place.
I would simply go with the cheapest option.

Thank you for your responses.

The parking space is 3m (10 feet) wide and about 6m (20 feet) long. In the current Teslas, the charging connector is located at the rear left of the car, so I planned the wall box at the blue point.

The vacuum cleaner would be plugged into the socket, and we found the position at the green point quite suitable for that. In terms of costs, we can choose the position freely. Both connections, of course, run to our apartment.

Or park in reverse?

Yes, it would basically be possible to park backwards, but my wife has already mentioned that she only wants to park facing forwards. It’s just easier to drive straight in, and that was also the reason why we chose the parking space there.
