Taking Delivery of R1S Tomorrow...Purchase RAN Charger or NACS Equivalent?

[pchutts]

Hi Team,

Taking delivery of a QM 2024 R1S tomorrow. Got a smoking deal and couldn't be happier. With NACS adapters currently being shipped and Rivian moving to full NACS down the road, if you were in my position would you buy a RAN charger or a NACS equivalent and scoop a third party adapter in the meantime?

With thanks. Appreciate your experience and perspective.

Your question is kind of confusing, a "RAN charger" is either typically a Level 2 RAN Destination Charger, or a Level 3 DCFC CCS Combo Charger.

The 2024 will be CCS and eventually Rivian will send adapters for the Supercharger network. On a Level 2 charger, you'll use the J-1772 plug. Don't expect the Rivian supplied charger to be delivered soon, as those people who took delivery 2 years ago are still waiting for this adapters.

If I were buying a new truck with the CCS Combo charge port on it, I'd go with the J-1772 plug on my home L2 charger. Why use an adapter every time you charge at home. Buy a 1772-Tesla adapter for those times when you will need it away from home.

Although Rivian will sell you their home L2 charger, it's pretty over-priced and there are several other options that will do just as good of a job for less money. If you're looking to install a Level 2 Charger in your home, then contact your power company and see if they have any rebates, and buy the charger they may require for said rebate -- I did that last year and the total cost for charger and professional install only cost $200 out of pocket.

If you're asking about what sort of L2 charger to use at home...

I believe that many people have suggested getting a 60amp circuit installed (so you can charge at 48amps) and get the Tesla Universal Wall Connector hard wired to that circuit.

The Universal Wall Connector has a NACS connector with an integrated J1772 adapter.

We took the "easy" road and bought the Rivian L2 charger when we bought our R1S a year ago. As soon as we got our VIN we asked them to ship the charger so that we could have it installed before we picked up the vehicle. Rivian did and we got it installed and inspected the week before pickup. I'll strongly recommend you hardwire your charger, versus a plug, whichever model you get. Yes - it might make it harder to swap to a different charger in the future, but you're going to have your R1S for a while so you won't need a different adapter until you have another EV with NACS.

Tesla's NACS charge port is dual-purpose, one plug for both Level 2 and Level 3 charging. Rivian's charge port is two parts. J1772 for Level 2 and CCS1 for Level 3.

RAN (not Waypoint) is Level 3, DC (direct current) Fast Charging. Those units likely cost $20-30k each.

The Tesla-made adapters Rivian is distributing to customers is for use at select Tesla Superchargers (Level 3). It's NOT for home charging.

The typical 240V home and destination chargers (including Waypoint) are Level 2, AC (alternating current). You don't have to buy the one Rivian sells. Only advantage it offers is app integration with your Rivian app/account. Watch State of Charge channel's reviews and recommendations on which to get. Out of these, there are two kinds, hardwired or NEMA 14-50 plugged. Hardwired will deliver higher current and shorter charging time. Tesla's Universal Wall Connector is a good option because it supports both J1772 and NACS. But know that it is still a Level 2 AC charger. And technically, these are all EVSEs, or power supplies. The actual charger is built into the car. Most hardwired EVSEs can deliver 48A. The mobile charger that will come with your Rivian can deliver just 32A.

We got an electrician to install a 14-50 outlet which we use for our Tesla and R1S. We use the charging cable which comes with the Rivian.

Tesla UWC FTW. One of the few EVSEs that can daisy chain multiples on the same circuit.

NACS >> J1772 and NACS >> CCS adapters are still useful for destination and DCFC, but not needed with the Tesla UWC, and not something you have to fiddle with every time you plug in at home.

Thanks everyone. Super helpful, informed responses. Much appreciated.

Big nope. CCS is Level 3 (fast charging). It is cost ineffective to install a fast charger at home. For the charging hardware alone, it's on the order of $20-30k vs a $500 Level 2 EVSE.

Futhermore, If one were to go through the expense of hiring an electrician to wire a home for Level 2 EVSE, best to be as future-proof as possible—i.e. buy and install one that has support for both J1772 and NACS. Why? because your next EV, or the person you sell the house to, will probably have a NACS charging port.

There's absolutely nothing wrong with using an adapter, as long as it is a quality adapter that isn't going to melt, or arc, and start a house/vehicle fire.

For those confused about the various charging interfaces:

*NACS = Supercharger

Congrats on the new R1!!

It sounds like your asking about home charging. Hands down I recommend the Universal Tesla Wall Connector. I have links to them on my website as well as a couple videos on my setup.

The UWC is future proof and can charge any EV out of the box since it has both J3400 (Tesla NACS) and J1772 all other EVs currently.

I have used a Lectron adapter to charge my Rivian with my Tesla Wall Charger since day one. Is there a problem with using an adapter?
Have never had any issues whatsoever.

Critically - if you expect to charge at 11.5kW (48A) you have to have a hard wired EVSE. Using 14-50R you’d be limited to a 9kW (40A) EVSE at best. Plus 14-50R/P can be prone to failure over time as the interface will get hot. It’s less of a problem is you go with an even lower capacity EVSE (like 32A for 7.6kW). The point being, if you want to max your L2 EVSE to match what the Rivian’s onboard charger can handle (11.5kW) then go hardwired.

As to what flavor (NACS or J1772), that’s entirely up to whether you’d want to have to use an adapter at home or not. With NACS you’d have to have a NACS to J-1772 adapter, with J1772, no adapter required at home - it’s native to Rivian and every non Tesla.

Some people find it a hassle to plug in an adapter and then plug into the truck, and then store the adapter when you're done. I used a Lectron adapter when I had my Lightning and it was a little bit annoying to do the above steps, but it's really a first world problem. If it doesn't bother you, however, it's not actually a problem. As you've experienced, there's nothing functionally wrong with using an adapter whenever you charge.

You mean J1772.
