My Frankenstein NACS Conversion (Poor Man’s Tesla Universal Wall Connector)

[shrink]

Got the Gen 2 Quad with NACS port. Also have a leased IONIQ 5 with NACS port. My wife drives a Gen 1 R1S Quad with J1772.

I’ll be honest. I was annoyed NACS won the charging port wars. I’ve been driving EV’s since 2011. Started with J1772 EVSE’s with a LEAF and Volt, was all Tesla for a while, and changed my EVSE’s accordingly, then all Rivian and changed my EVSE’s again. So I went from J1772 to Tesla to J1772 and now back to NACS.

Anyway, while the Gen 2 R1T Quad and IONIQ 5 both came with J1772 to NACS adapters, I find them annoying for home use. Pressing the release latch on the J1772 handle sometimes leaves the adapter in the charging port, then it’s an extra step to remove or use 2 hands to remove. That’s just inconvenient - especially if carrying something. I’d also prefer to keep the J1772 adapter in the car for use in public.

So I wanted a native NACS handle for home use. I didn’t want to swap out a working EVSE if I didn’t have to do so. Only ChargePoint sells a NACS conversion cable and I was unsure if it’d work with my EVSE.

My solution (thanks @A2ZEV)
1) Bought a second J1772 adapter to keep on the home EVSE (and keep the OEM adapter in the car)

2) NACS extension cable

Pics are below. Working perfectly so far. Loving the convenience of a native NACS handle - and flexibility to remain on J1772.

I’m using an old school Tesla-branded Clipper Creek CS-70. This thing is 14 years old and I got it free when I bought an OG Tesla Roadster (as a CPO). It can charge at up to 70 amps/16.8 kWh. I used to have the horrific Tesla Roadster charging handle on it. I converted it to J1772 at some point. The J1772 cable and adapter are rated at up to 80 amps. The extension cable is rated at 48 amps and since the Rivian can’t pull more than that I’m thinking we’re good to go here.

NACS is clearly the superior technology for public chargers. That huge, clunky, easily broken when dropped CCS1 handle clearly designed by committee.

NACS connector will break too if the end portion is pointed down when dropped on to concrete. Ask me how I know that

Interesting idea. Perhaps worth considering creating some kind of a wall-mounted cable holster that you can plug the J1772 into, that has pins and a cord with a NACS connector on the other end.

Can't be true, NACS is superior

Was really hoping this was for a CCS to NACS conversion in the truck itself when I saw the title.

Maybe one day....

That would be ultra cool. This is what I did and almost as convenient (and doesn't require redundant cabling). Wanted native NACS w two load sharing chargers (one inside the garage, one outside). J1772 for Gen 1 R1T.

Since I use the outside one almost exclusively for the R1T it is always connected. I thought about locking the adapter, but they are now a dime a dozen and I always have the adapter in the truck if someone steals it. I have had several neighbors and plugshare users use it (with my permission), so the convenience is nice. Both wall units are mounted inside the garage.

(and yeah, NACS > J1772)

I'm with "the.phd", I too am interested in a conversation to NACS in the truck.
