2022 Rivian R1T's Fast-Charging Performance Is behind the Best

[kanundrum]

Rivian claims that its R1T electric pickup can withstand peak charging rates of up to 220 kilowatts on a DC fast charger. In the future, it says, its vehicles will be able to accept energy at a rate of 300-plus kilowatts after an over-the-air update. This would put it in the league of Lucid, which already touts 300 kilowatts; Tesla, which CEO Elon Musk says will soon upgrade its Supercharger network to more than 300 kilowatts; and the Porsche Taycan, which can currently accept up to 270 kilowatts.

@SeaGeo We got another "quote" seems official.

Their charging curve is drunk with a poor sense of direction...

Honestly I can see why they are limiting or trying to massage it!

also, what's up with the taycan curve?

There is definitely room for improvement here, especially in the critical 25-70% range. Hopefully at least some of this is attributable to early software issues as also reported with the infotainment system.

I don't understand why RIvian would hand out these pre-production trucks that they must know have a few quirks to the press. It just makes it obvious to me that their communication and marketing department are in their infancy.

I personally think that they are just being super conservative right now and will allow higher rates and a more aggressive charging curve as they build up the data profile from more end users. The amount of data available should grow significantly over the next 3-6 months, which will allow them to make significant adjustments.

Because it would be much worse press to give them a latest and greatest version and then IT has issues during their testing. A preproduction unit gives them some wiggle room for excuses for any bugs or performance issues.

The entire graph is wrong. I've never once got that bad of a curve on my 2020 Taycan 4S. In dozens of charging attempts that would have been my worst curve by a large margin.

Fake graph, bad data.

Yes, very likely.

Rivian also describes their BMS as being "smart" and adapting to driving and charging behaviors. This is great but it also suggests that Rivian needs to communicate how certain user behaviors might impact charging.

At this rate going from 30% to 70% (~50kwh) would take ~30 min. Yikes.

Very likely based on your hopes?? Maybe it'll get slightly better, maybe they'll decide it's best as is. You have no way of knowing. People should buy the car as is and if it gets better it's just a perk.

Can’t help but wonder about temperature. I consistently hit 125kW in my ID4 in the summer, but haven’t seen more than 55kW this winter, charging at similar SOC below freezing. I feel like we are not going to see faster charging until the weather warms up. I don’t know if teslas are impacted this severely as well but even after driving up and down mountain passes (same route as that Ike gauntlet) I haven’t seen fast charging in the cold.
