120V can charge at 48A

[Dark-Fx]

Finally got around to building my OpenEVSE. Wired it for 120V and set the advertised current at 60A. The truck will happily pull up to 48A on 120V. I knew it would do 32A on the portable, but I just had to find out if it'd actually be able to pull the full 48A the charger supports. It will.

Not sure if this will help anyone, but I find it extremely interesting.

5kw on 110v means you are only pulling 30A. BUT….very few 110v outlets are run at 10 gauge. Most are run at 12 or 14 gauge, meaning you very well might trip a breaker (hopefully) or worse (set your house ablaze or damage the OpenEVSE).
If you actually go over 30A, you may need to worry about melting your lines too. Be careful!

Good to know. It is a pretty edge case that a person would have a 60 amp 110v circuit and not a 240, but it could happen. Now I want to look and see if the is an official outlet for that.

? The OpenEVSE says the Rivian was pulling 47.7A. 120*30 is only 3600, I don't think the Rivian app rounds up either. "The outlet" I'm currently wired to has 6 awg wiring, and only did this as an experiment. I'm not going to bother charging like this ever.

NEMA outlets run up to 50A for 120V and 60A for 120/240V. It's conceivable that someone might only have access to a 5-50, which is the 120A outlet, but should still only pull 40A continuous max through it.

NEMA outlets run up to 50A for 120V and 60A for 120/240V.

So, obviously, one could get 60A @ 120 from one side of a NEMA 14-60.
