Tesla Supercharger Charging Speed

[ActionableDave]

This isn't true.

I think the implied part of the last post was if your charge endpoint is over 60%; as others have said, it takes speed hits at 60/70/80

At least part of the temperature decrease is related to State of Charge.

I think part of it is also related to battery temperature. Not sure of that though.

Best to all!

Received my A2Z Tyhoon Pro the other day and went to test it out yesterday. Plugged it in to the truck connected the CCS cable and within 20 seconds it was charging. I was at 14%SOC and it quickly ramped up to 204kwh. I proceeded to start playing with the new haloween costumes among other things and noticed after about 30 minutes of charging I was down to 65kwh. This was at around 75% SOC. No limited charging messages, no heat at the handle or the adaptor. Anyone else experience such slow speeds with no notice/messages?

Not my experience. Screenshot taken during a Tesla SC session today.

Normal.

I’ve been to 3 different Tesla 325kw superchargers with my 2025 gen2 R1T max with the Rivian supplied adapter and have only been getting like 60-100 kw max. Most of the time closer to 60-70 kw. I’m thinking it could be the adapter maybe causing the slower speeds?

I’ve preconditioned every time and I’m not showing up with like 85% battery more like 25-50%. I get faster speeds at CCS (non Tesla) DC fast chargers which is why I’m thinking it could be the adapter. Just curious if anyone else has had a similar experience.

See if Rivian will exchange your adapter for you or help with some troubleshooting. I get between 150kw - 215kw with an adapter. Rivian or A2Z its the same for me.

I've seen slow Supercharger speeds too. I get a "speed limited by charger" message on my Rivian UI. I get better/expected results at other providers.

I wish I had my a2z adapter with me to test it out but it’s in my wife’s R1S.

I have had higher and sustained charging speeds at the V4 chargers over the V3 but a good margin. Also charging in the shade and keeping the last foot of the charge cord covered ensures no derating of charging speeds. Anyone else have the same experience?

Charging an EV is not the same as filling a gas can. This is electrochemistry mixed with two separate controllers that communicate. Lots of variables that ensure the charging will be different every single time. Completely normal. Any max rating would only be for perfect conditions in the battery, onboard controller and the charging supply controller. Any component may reduce the maximum charge capability.

It may not be your adapter. I've had the same experience as others have stated here. I typically hit the DCFC stops with 10% to 15% SOC, and preconditioned. At maybe 70% of my Tesla Supercharger stops, I get flawless charging, topping out at 212 kW. At the other approximately 30%, I get the dreaded "Charging Speed Limited by Charger" message. This happens both with my A2Z and Rivian adapters, and under similar outdoor temperature conditions on the same cross-country trip.

So the problem may not be at your end. It may just be the small sample size of your SC attempts. If you have a chance to charge at others you haven't visited yet, that may be worth the try. To rule out other factors, try to get there with a low SOC and a preconditioned car.

Just odd because I’ve never had this experience with my gen 1 R1S, only my gen 2 R1T.

I’ll keep troubleshooting and see if anything changes and if not I’ll make the dreaded service appointment.

It's pretty unlikely there is anything wrong with your truck. Plenty of reports of Superchargers under delivering power.

A suggestion I have is to make sure the Rivian battery is 80 deg F or higher for fast charging. As it gets colder now it can take 30 minutes or more to warm the battery that much.

Also, if you are in the vicinity of a iONNA charger try using the NACS handle on the iONNA charger with your NACS to CCS adaptor. That could help rule out adaptor/truck issues.

So I just tried using my wife’s official Rivian supplied adapter and I’m getting better speeds at the same Tesla charger I tried last week.

Not blazing speeds, but better than the 60-70 kWh I was getting last time. I’m going to try my adapter again at this same charger showing up with similar battery level and see what I get.

Stay tuned .

204kwh

Wow! That's good! I've hit around there once or twice when my battery was (well) below 15%. Usually pegs in the 140-150kW range until it hits 70%.

We're planning a road trip for the week after Christmas (weather permitting). Will see what we get when we are on the road.
