Battery Losing Range at Low SOC

[johnse]

I know that with Teslas the BMS will do cell balancing at the top of the charging process... between about 92% and 100% IIRC. So it's often suggested to charge to 100% occasionally and immediately drive it so it doesn't sit at the high SOC. Subsequently running it down to single-digit SOC helps the BMS to calibrate the present capacity.

Is that also true for Lucid?

My 2017 chevy Bolt does a better job

I don't know why I find this post so irritating, but I do.

Because you weren’t aware you could have had a much better car for much less money!

True for all lithium-based cell chemistries, which includes Lucid. But also good to remember that this does little for the health of the battery itself - rather the opposite if anything. I've encountered people who almost religiously tried "calibrating their battery" by ramming it up to 100% and going as deep as 1-2% as often and once per week. Totally unnecessary, and likely to increase degradation.

Your 2017 Chevy Bolt was not on topic. What’s that saying about throwing stones in glass houses?

That's fair

Yes, it's normal. Low SOC affects voltage and range drops faster. Try to stay above 10% if possible.

Such different mindsets here.

Remaining miles has always been a snapshot guesstimate. Audi's for decades still give one guesstimate when hot, at 9pm after a drive when below 1/8 tank, and a very different one when cool the next morning. Normal.

Drove with someone in a Tesla last week for 100 mile trip. I asked if we could stop for coffee. Said we couldn't. Not enough juice to stop and then to get home. He purposely left his house in the AM with the level of charge at just enough juice so he would arrive back home with a few percent left. Has two Tesla chargers in his garage. Didn't see the need to top up overnight and start out with a full battery "since (he) would have a few percent to spare.".

I have found, not really. Pleasantly surprised how little juice Dog mode uses.

Keeping the car hot or cool does not use a lot of energy. Cooling a hot car or heating a cold one does use alot of energy.
