Tesla warranties the batteries for 8 years unlimited miles and they recommend charging to 90% every night. I'm just going to do that and not worry about it.
Makes sense...I wonder if lease holders are as diligent.......
I charge to 90% now, but I also don't recharge on a daily basis, but rather every 2-3 days as my daily driving is 40-60 miles.
I don't know if this is a good thing to recharge every couple days, or is it better for battery life to bring the battery back up to 90% for better battery health.
Advantage of every 2-3 day charging:
- don't have to plug in nightly
- can use summons every morning with home link to open garage, back up the X and close the garage from my phone while drinking my coffee in my kitchen watching the show
... where is 4.0v relative to state of charge? maybe 75%.
...
one other thing i would recommend is to avoid high rate charging at temperature below 0c. especially when the cells are above 75% soc. tesla electronics may prevent this
...
keeping below 4.0v may double or triple life time compared to a full charge every cycle, i suspect.
...
i think that really deep discharge should be avoided as then the graphite empties of Li and the cell potential rises to the point where the SEI on the graphite side can be damaged. keep the cells above 3.0v per cell (no way you can tell that) but that would be about 98% discharged. so do not discharge beyond 98%.
...
My X spends most of its time plugged in, so I keep my charge a little lower since I also don't need the range. Lately I've been doing 70% and it's been difficult mentally (I like to see a full battery for purely aesthetic reasons), but practically I still don't drive enough to see my charge fall below 50%. What @daxz said about voltage in relation to SOC makes a lot of sense.
It would be nice to know for sure how an average SOC affects cell longevity in the Tesla battery pack. However it seems that since Tesla added lower charge limits (to 50%), it was probably for a reason, I'm just surprised that everyone is saying that Tesla recommends 90%.
I've read elsewhere that 50-62% is the ideal charge range for the Tesla, so maybe work with that?
The main problem with a lower charge level is that the pack goes out of balance . . . .
