Rivian R1T charging curve test 20-80% [by TFL]

[kanundrum]

For fun because it stopped at 151kw I am wondering if @TFLtommy will you be doing one more DCFC test on a different charger to see if EA MAYBE was throttling for some odd reason.

Not surprised TFL didn't get a proper curve. At all.

What's improper about it? Looks good to me.

Of you're concerned by this, I've had multiple owners tell they've seem 180 and 190kw.

Don't doubt it. What you will get varies.

To me, this is a fairly low value data point, and I'll still be waiting for InsideEVs to do a charging test and range test.

It's as good as any other in that it adds to our appreciation of the dispersion of charging curves we can expect on the road.

An analyst doesn't throw away data he doesn't like. He tries to find out why it doesn't agree with his assumptions going in.

I appreciate the feedback (i’ve seen lots of it on this forum) and say what you want but we DO have tons of experience in towing and off-road environments.

On our rocky mountain towing test quickest rate was 150kW as well from 15%.

I don't at all disagree with the other experience.

That's very weird that it only pulled 150kw at 15% after towing too. It sounds like (at a minimum) they need to work on making their charging curve more consistent.

In any case, thanks for trying to get the data!

Yeah, I am going back to edit my comment. Improper was the wrong choice of words.

That's bad.

I can't tell if the answer means it already preconditions so there's no user selectible setting, if they mean preconditioning as a whole doesn't do anything, or if the vehicle is currently incapable of preconditioning. There are varying degrees of bad.

Starting at 20% left is too high. That's still 63 miles left. You're better off in almost every EV trying to do 10-70% between stops instead of 20-80%.

Many feel that staying out of the bottom 20% is as important for battery life as staying out of the top 20%.

I asked the development team about preconditioning via nav and they said it doesn’t have an impact.

As the car had been driven extensively before the charge the battery would be at the proper temperature and no preconditioning necessary.

I’m looking forward to seeing all of the other tests! A 0-100% charge test would be great too if you can work it into the schedule.

I don't think it's too high as a frame of reference. I actually think @TFLtommy chose a good percent for to reflect someone typically driving. I am just dubious that this is the "ideal " curve for the Rivian even for this portion of the curve.

It's there, there's bugging to unlock. TFL just doesn't have the experience to get a "ideal " curve on a test yet.

What sort of experience does it take to get an "ideal" curve? I owned a Model S for a couple of years and my supercharging strategy was the same the very first time I used as it was the last time.

 

[SeaGeo]

My 'hate' derived from being turned off at their entitled whining. I don't expect MotorTrend or Edmunds to weigh in because I'm not sure they know what a "charge curve" is. What TFL provided in this video is one data point. I'd ultimately prefer those with a demonstrated proficiency in charge curves to weight in.





I'll be waiting for something to pop up from Tom my money is on him getting to it first. Really curious as to the 70mph range test.

Oh, he will. I'm pretty curious to see what they get in their towing test.

@TFLtommy , if you have Brian Gase’s contact, ask if Rivian is currently software locking at 150 on all chargers and if/when they would push an OTA to unlock 200. Thanks for the video.

Tbh, I kind of suspect it's either the battery not being warm enough for whatever reason. Or EA shenanigans on a specific piece of hardware.

Did they mention lifting the charging cap in the future? There’s been speculation on if the 300 kW that they’re advertising is for current production models or future ones

They aren't. I've had multiple owners say they've gotten ~180 to 190 kW.
