I have been looking at preparing for charge at home station. I am sure I could just google it and I probably will... But I would love to know what people had to do to put one in. I am about to put a 60 Amp sub-panel outside on my shed, and am wondering if that is good enough.
I have some info, but do you mind if I move this over the Car >> EV thread?
And here we are
So at home you can use a 120v (Level 1) but clearly if you can accommodate a 240v Level 2 it's much better. L2 chargers (not to be confused with Tesla fast Level 2 public systems) are generally going to be up to 40 amps, and there's standard protocol that you should only charge about 80% of the circuit spec, i.e., a 40a charger should be on a 50a circuit.
The max amps for the circuit will depend on the existing panel configuration. We went with 50a, we have existing 200a service, and we had space for the 2-pole breaker right in the existing panel.
If it's not a hardwired charger, it'll use a NEMA specification for the receptacle, with a 50a/240v that would be either an N6-50 or an N14-50, for charging an EV, those are effectively the same. The 14-50 is common in RV parks, the 6-50 is used by equipment like a welder. The big difference is the 14-50 supports both 120 and 240 so it's useful for something like an RV that might have lighting but also an oven. Because it requires a dedicated neutral it can be more expensive to install.
I had the simpler N6-50 installed. We got a pretty great deal, the install, parts, from a certified electrician was ~$220, but a few things about that price: simple 18" wire run, existing panel with no issues, the whole area easily accessible on the back wall of the garage.
I like that I can easily unplug it, and if the need arose, swap out chargers.
While we're on the subject, these types of boxes aren't really "chargers", they're an EVSE, it's basically an AC switch, the actual charger is built into the vehicle.
There's two plug specs: Tesla and a J1772, that can be used by a Tesla with an adapter they provide.
We use a Grill-E Smart charger, it's fantastic, 40a, N6-50, 3 year warranty, built like a tank, 24' cable.
I need to jet, but I'll add a few more things in a bit
