I do not have a lot of miles on yet after 2 days of ownership, but I did my first DC charge this afternoon (Electrify America) on one of 6 350 kWh chargers at their Cadillac, MI location. I was the only vehicle charging. I drove about 60 miles to get there at highway speeds (60-80 mph) in moderate rain, 37 degrees, so the truck was not cold. I opened an account with EA yesterday, and charge session started within 60 seconds of plugging in and tapping my iPhone on their reader. First impression of EA is good!

The R1T started the charging session at 39% SOC. Charge rate began at 166 kWh.
I went into Meijers for about 45 minutes so could not monitor charge rate, but here are some points:
SOC 39% - 80% : 28 minutes (based on text notification)
SOC 39% - 91% : 46 min. At 91% charge rate observed at 41 kWh
SOC 39% - 100% : 1 hr 18 min.

In Normal mode at 100% SOC the truck indicated it had a range of 286 miles. Changing to Conserve mode bumped that up to 310.

I was not tracking my range/efficiency for the drive to the charging station, but I noticed shortly before I arrived at EA that the 15 min avg efficiency number was hovering around 2 mile/kW while running 60-80 mph. I was in Normal mode, low suspension setting, cabin heat at 70, headlights and fog lights on, radio on, radar detector on.

For the drive home I selected Conserve Mode. The road was still wet (light rain & 36 degrees, minimal wind) and was in a slightly hilly area with cruise control set for 60. After about 20 minutes I checked the 15 min avg efficiency number and saw it was up to 2.52 mile/kW. The last part of the drive I lowered the cruise to 55 mph and saw the 15 min avg number go up to 2.82. The road for this last section was flat. Way too early to know how accurate that number is, but it does give some idea of how Conserve mode and lower speeds impact range. I'm very curious to see how other do with range.

My Wall charger was delivered yesterday and I am waiting for an electrician to install it, so I am limited to public charging options. I tried the portable charger at 120v and had a charge rate of about 1.5 mile/hr. :-(

Thank you for sharing these details. I hope your wall charging installation goes well.

Very insightful.....we're all hoping once Rivian has enough date from the field on battery specifics during charging, etc., they can allow for a greater charge rate.....thank you.

Looking like conserve mode makes up for lost range due to tires….

Tell me you're from Michigan without telling me you're from Michigan.
I could've said 'Culvers' which is just as close and it would have been a little more vague... :cool:

I’ve still never been to Culver’s and we have one in my town in Ohio. ??‍♂

Haha. Could be Ohio as well!
Is Meijer(s) with the s a thing in Ohio too? When I worked there as a kid in Michigan they drilled into us that it was "Meijer" over and over and over. No one ever changed the way they said it.

SOC 39% - 100% : 1 hr 18 min.
So probably something like 60kw at 80%, and 41 kw at 90%. With about 40 minutes from 10 to 80% at best.

I'm really not thrilled with the +50% curve so far given how large the pack is and how long they've been developing this. I'm really curious to see if Kyle gets much different.

Haha. People born and raised here seem to say Meijer(s) a lot more than transplants. We’re originally from NY, so we’re the odd balls on how we say some things.

Judging from his tweet while they were trailer testing, it didn't seem positive - though seemed like a lot of that was down to the charger output. Guess we'll see.

Admittedly based on threads in here I’m way less concerned about DCFC charge speed than others. Probably because I do not use them that much. The times are way faster than my MS and I never found a need to complain about that charge rate when traveling.

Just my take, please check my math, but I read it like this going 39% to 80%.

That 41% of battery is 55 kWh so an average rate of 2 kWh per minute or or 120 kWh per hour. Based on 2.32 miles per kWh which is EPA rating for the 314 miles, that is 127 miles in 28 minutes. Not 120 in 20 Rivian claimed but the session started at 39% so probably would have been a little better going 20% to 61%.

Appreciate the insight into the charging. While this isn’t the best real world data hopefully it’s software capped in some way. If not it’s not a dealbreaker for me since most of my charging will be at home and any road trips will just require a bit more planning. Don’t mean to derail your thread but what are your impressions of Forrest Green now that you’ve lived with it for a couple days?
