I had the foolish idea of installing a Tesla charger at home to charge my Bolt. I’ve been unable to ever use it.
The wall charger works fine with Teslas.
My car and adapter charge fine at Tesla superchargers.
But the home Tesla charger refuses to charge my Bolt.
(Yes I disabled vehicle restrictions and tried all sorts of combinations of settings for weeks before giving up. Tesla support was useless of course)
They make a "universal charger" for this express purpose. It even has the adapter embedded in the holster, so you can either grab just the NACS connector, or the connector + J1772 adapter in one smooth motion.
Just don't try to use that adapter on another NACS connector like the Mobile Connector, it'll get stuck and you'll have to do some magnet shenanigans to get it off (ask me how I know...)
NACS on Level 2 has the same number of pins, but speaks a different protocol than J1772, so just a normal "dumb" adapter won't work. You either need a Connector that can speak J1772, or a TeslaTap.
> I thought tesla even made a j1772 native wall connector.
At least a few years ago, they would openly recommend it for non-Teslas.
I thought NACS brought some changes to Level 1 and 2 that aren't backwards compatible with J1772? I know there's an oddball voltage in there so you can put a NACS charger on a lamppost where J1772 would require a transformer; but I didn't think there were protocol issues too.
J1772 is 120V or 208-240V. Those are by far the most common voltages in the US. (208 is what you get when you take a US 3 phase system and connect to two phases - this is somewhat common and most people don't know or care that their apartment is wired like that). I have seen other voltages at industrial sites, but I wouldn't expect that in a lamppost.
Publicly accessible piece of equipment that could have a pseudo-trusted connection to an internal network (since they're connected to the Tesla Cloud(tm)).
Picturing someone rolling up to a charger outside of a large office building, 'plugging in', exploiting the charger via the communications, then using the charger to pivot inwards.
Or just for the spirit of actually owning the shit you pay for.
