I’ve had my p3d+ for just over 2 yrs 26k miles. The end of July I happened to start doing this method before the OP started this thread. I stopped charging everyday and only charged when it was 20-30%....letting the car sit/sleep at those low SOC for at least 2-3hrs before charging back up to 90% and letting it sit at 90% for a few hrs. I don’t use sentry mode...so it’s always off. I went from plugging in daily to only charging every 4-6 days. My 90% went from 248 to now 260.
Takeaways from my experience:
1) I’ve done 15 deep charging cycles since I started end of July and only got to 260 with my last two charges....so it can take some time depending on how many miles you drive.
2) caused some range anxiety that I never had before. I’m the never let my gas tank get below 1/4 kind of guy. With having a varying work/kids/family schedule there’s been times I would have to calculate and plan for how far I might be driving to make sure I had enough SOC to get through my day/trip.
3) confirmed my lack of desire to drive at low SOCs. One of the main reasons I bought the car was for the acceleration. There’s a noticeable drop in power at lower SOC (as seen by MPP’s dyno testing) and is one of the reasons I prefer plugging in everyday. Last night I ran into a modified e92 m3 on the highway and had some friendly pulls. With only 50% SOC it left me wondering how it would have compared if I had a higher SOC.
Not sure how much longer I can keep this up...but at this point I have to keep going until the range levels off lol.
Here’s a screen shot from STATS showing calculated 100%
