My spouse and I run a small farm stand outside town in rural Vermont, and this spring we went from one PHEV to two — I've had a Pacifica Hybrid for about a year and a half for hauling stand inventory and the kids, and my spouse just picked up a RAV4 Prime for the commute. We've got a detached two-car garage with two 15A outlets on the wall, original to the building as far as I can tell (it's a 1970s pole barn we converted). Called three electricians in April about a real Level 2 setup — dedicated circuit, maybe two spots — and the earliest anyone can actually get out here to look at the panel is late September. Panel's already pretty full, so I'm guessing this turns into a subpanel job, not a quick add.
In the meantime we've been running the factory 120V cords that came with each car, one per outlet. Don't know if the two outlets share a circuit — the panel labels are from the previous owner and half of them just say 'shop.' Ran both cords through a cheap two-outlet splitter for about a week when we had houseguests, and it got noticeably warm to the touch after a couple hours, so I unplugged it and stopped. Before I do something dumber waiting four more weeks: what actually works here?
