I have a few questions on supercharging speed and impact on battery life.
I have a 2013 S P85+ purchased used a few years ago. It has lifetime free supercharging, regardless of ownership transfer.
Max charge equates to around 260 miles. But I think now it is a little less than that.
I have a dryer plug @35 watts at home that gets me 17mph charging speed, enough to get a decent charge overnight.
But I found that my electricity bill increased a lot when I charged at home, so I switched to only supercharging. I'd combine trips to the shopping center, for shopping or eating, with supercharging so I didn't have a lot of wasted time. Or I'd meet up with my old friends from my former workplace, where there is a supercharger. I don't charge all the way up, only to 80% or sometimes as much as 90% if I am unable to return to my car soon enough.
Even when at a 150kW supercharger, even with a very low battery the car would not charge much above 75kW ~ 80kW, and would of course drop as it charged.
So I have learned to accept the time involved to charge up, and find ways to pass the time. Since I am retired now, it is not a big problem for me.
But I am concerned about impact on battery life. The car, though now 8 years or so old, still has less than 40,000 miles on it. I've read, here and there, that for battery life and total range capacity, etc., it is best to NOT supercharge. I think I even saw some mention somewhere that the best thing is to use only the 110v charging to top off every night (though I frankly don't know what you'd do if you drive more than, say, 30 miles per day).
I would really like to understand what the best practices are, and what the worst case scenario or other general adverse impacts might be, with respect to supercharging, all the time or otherwise. Will always supercharging to charge have truly deleterious impact on battery life, capacity or charging speed, and if so, how significant might this be?
Also, I sometimes do not charge until the car is around 10% of battery capacity, as I prefer to minimize my trips to the supercharger. Does this create any potential battery life (or other) issues?
Thanks in advance for any and all info and advice.
