LR RWD Battery Rebalance Success!

what app are you all using? is it a subscription service like those other sites?

The OP appears to be using TeslaFi and I think the plots with the orange dots are from Stats.

Mine has had its ups and downs:

stats is a mobile app?

Yes, iOS only.

Funny thing: here’s my graph - note the dip around 12k miles and the recovery. But I did absolutely nothing to “fix”it. No deeper than usual discharge, no higher than usual charge limit.

Here’s mine. I had a similar dip and recovery but didn’t do any balancing procedures. I think this might be a product of a BMS software bug.

Can you tell us what your charging regimen is, since you both have no deg and both state not having done anything rebalancing, etc.

I generally charge to 75% and avoid going below 20% but charge to 90 or 100 when I need the range. I never let the car sit at extreme charge levels (high or low) for any period of time.

When I need range I have gone as low as 3% but my daily needs are about 50 miles so I try to be gentle on the battery.

Edit: I only supercharge on road trips.

I'll try re-balance if I ever encounter a range issue. For now, I follow the manual: charge to 80-90% daily and keep plugged in all the time at home. I will supercharge on road trips.

Is there an Android equivalent?

Sure. Charge limit is set to 82-84% on weekdays and 90% on weekends (that's when I do most of my driving). Typically charge at home from a 30 amp outlet and the car is almost always plugged in when I'm not driving. Charge to 95-99% 1-2 times a month and make sure to drive right after I stop charging if I go above 90%. Supercharge 10 times a month or so, usually to 80-85%. So, in other words, nothing unusual.

Thanks for both of your answers. Mtndrew's charging seems very conservative, charging to 75%; while ilyak's is usually conservative, 82-84%, but a little more aggressive use of supercharging. The only commonality is both keep their normal charge limit near 80%, between 75% and 84%, as opposed to charging up to 90%.

I used to charge to 75-80% regularly. And then of course it was suggested that I should be charging to 90%. I did that for about three months, and of course there has been no benefit.

I think that the idea of the slowly permeating call to set the mark at 90% is not that there will be any benefit per se, but rather that it doesn't do any actual harm.

I believe that the 90% thing originated from Musk in a tweet about unbalanced packs showing reduced range.

If I start off by telling people that I charge to 90% all the time, they tell me that perhaps my problem is that I'm charging too high. If I start by telling them that I charge to 80%, I'm likely to hear that perhaps my problem is that I'm not charging high enough.

Or that I should go to 100% and 10% more often. Or that I should do it less often... you get the picture.
