Legal issues aside, is there enough power there to make it worthwhile?
My home has a 200A meter, and at 240V, that's 48 kW. Let's round it up to 50 kW.
A Level 2 charging point is 50 kW, and EV owners sneer at Level 2 chargers because they are too slow. A supercharger is up to 200 kW and more.
Worse, I share one ground-mounted transformer with 3 neighbors (we have underground utility). This transformer is in my neighbor's yard, and here's a photo of it. The label on it says 50 kVA (I magnified the label to make it legible).
So, although each of the 4 homes can draw 50 kW, they don't expect us to do that at the same time. That transformer would blow!
And indeed, even when I ran the 5-ton central AC 24/7 in the 115F heat, my consumption was only 5 kW on the average. And if each of the 4 homes did that, that transformer still delivered only 20 kW and had plenty of reserve. However, it cannot handle all 4 homes charging EVs at the same time, unless the charging power is set down way low.
PS. By the way, I never looked at that transformer really close until recently, when they changed out the 40-year-old transformer that was leaking oil. This is the photo of the new transformer.
