R2 Battery Capacity / Range Options?

[RivAW]

Exactly! One of my daughters goes to a school that's 124 miles from our house - If I could drive my R1S Gen1 Quad in conserve the entire distance I might be able to do a round trip without charging, but it's just too close to do so. I typically arrive at school with 48-50% battery left. There's a Tesla station at a Sheetz convenience store that we usually hit either on the way there or on the way home. I pull in, plug in, use the restroom and get a snack and come out and unplug and we're on our way. It really doesn't take any longer than when we used to do the drive in our ICE, except that I don't have to stand by the pump in case the auto-shutoff doesn't work. With 8-10 minutes of charging (and the ability to start pre-conditioning the battery about 30 minutes before we arrive), I then have a comfortable margin for the trip.

This is because you are an educated EV driver….and is what people need to understand!

I care more about the charging curve than range.

Will it charge at 200kw for a long time or only for a small 15% window?

I prefer more frequent but shorter stops on long trips.

I usually aim to arrive at 5% charge and leave before 50% when the rate slows way down. But if the curve is better it would be nice to stay to a higher %.

Planning to arrive at 5% is something you get better at the more you drive. If during a drive you realize your estimate is way off just slow down - can go twice the distance at 50mph as 80mph.

Also 0% had a reserve - usually about 15-20miles.

An R1 will charge at >200 kW until about 45% SoC. Where does your 15% number come from? Why would you assume the curve will be significantly worse than the R1?

I've done a lot more charging with Teslas and their models vary greatly with charging curve. Some Model Y are good others are horrible. Yes some throttle below 200kw around even 20%. Depends on the battery chemistry, kwh size, and likely other factors. On the flip side the Tesla use so much less watts/mile they still charge "faster" than a Rivian in 'miles/hr' of charging possibly even for the whole session.

R2 is much smaller KWH pack than R1 so might not be able to sustain as high of KW rate as long.

Lots of people only look at the miles of range when comparing packs. I'm just saying the Charging curve is much more important if trying to minimize time at chargers on long road trips.
