I am the original poster and wanted to mention this is resolved. The answer, which isn’t great, is that the math they use to estimate max capacity has some serious limitations. When I initiated this post I never let my batter “rest” (sit at constant charge, with sentry mode off, for 4-6hrs) at...

Ah man, I’m the worst

I’ve tried and it hasn’t helped. The driving habits thing is interesting. Bc it’s hot down here, we blast the ac’s and drive 80mph it sounds like it may be adjusting to reflect that we should expect lower miles of range for a given SoC. If true, it could mean our batteries are totally fine.

What makes you think the driving habits factor is bs?

Possibly the most useful post so far, very interesting. So because I drive lead footed it may be saying that I have less estimated range, but still may have something lose to 82 kwh of capacity?

Very helpful. The previous driving habits could be key. Does that mean because I drive lead footed that my estimated range went down but not necessarily the kwh capacity of the battery?

Will give it a try this week and report back. Thank you much!

Interesting, thank you

Very good to know but not sure that’s my issue. I have sentry mode off at work and overnight in my garage.

Thanks. I hope you’re right. When I look at the scatter plots it seems like I’m on the very high end of degradation. Do you know how much is “normal”?

I admit I occasionally mash the pedal but even when I’m driving normally I feel like I have excess degradation. My 9% loss has been pretty evenly spread across the months I’ve owned it regardless of how much I use the acceleration.

I did some quick math: i use 15% of my batt in 30min. At that rate it would be fully discharged in 3.3hrs, which is about 3x the rate I charge it with a 220v 50amp circuit. Might not be as fast as supercharging but it’s getting close. I realize I’m mixing charging and discharging but it’s the...

I’m showing 9% degradation after 9k miles and 5 months. I think it’s because I regularly cruise at 80mph with the AC on max. There was another thread of a guy living on top a hill that degraded fast. I’m suspecting these cars don’t do well if you require sustained high discharge loads. Do you...

I have also taken exemplary care of my battery but have almost 9% degradation after 5 months and 9k miles. I pretty regularly cruise at 80mph with AC on full which is probably similarly taxing to the battery as driving uphill. Unless I got a lemon this is the only thing I can think of. I’ve...

Hello everyone! So, I read a lot about proper battery maintenance (or so I thought), but I’m sitting on 8% degradation after 5 months and 9k miles… which sounds like way higher than most people experience and is pretty worrisome. I charge my battery to 80% everyday as soon as I get home from...
