New Low Mileage Owner Charging Approach
I spent hours, no days, reading and re-reading the many threads (like this one, at least twice) and opinions on this subject while researching before ordering my new MS...
For perspective, I've had my MS for nearly a month, and I'm a very casual driver: Most days I drive 0-15 miles, a couple days a week perhaps 40-50, and perhaps one or two times a month go on road trips where I'll use most of my charge in a day, or perhaps I'll need to charge while away from home. I live in SoCal -- no extreme climates like those with lots of white stuff on the ground, or owners in climates like Arizona where I lived for a time and it hits 115F+ for days on end during the summer. I'm an anal kinda guy when it comes to taking care of my rides in just about every way, and keep them generally 5-8 years. The way I'm approaching MS charging is:
- I plug my MS into my HPWC every time I get home, if I don't have another planned errand that day; Charging begins at 12:05AM if MS decides it needs it, so I get the best rates; With my dual charger and 100-amp circuit, I could fully charge my "empty" MS to 100% before the cheap rates end each morning
(That was a purposeful decision on my part before I ordered my S90D and set up the electrical in my garage. Is it overkill, perhaps yes to a large degree, but I have no anxiety about possibly not having a charge in an emergency and I don't have to overthink it either).
- I leave my MS at the 90% default charging level
- If I'm going on a major road trip (only once so far), I use my Tesla App to bring the charge up to 100% when I wake up in the morning, then take off within an hour or two at most when I'm ready
- I would only bring my default charging level down to 50% if I were going out of town for several weeks and was going to leave my MS parked in my garage the whole time
I too figure if Tesla Engineers who design MS and are responsible for it's 8-year warranty went to the trouble of building the 90% default, setting the car to that default upon delivery, and say in the Owner's Manual to keep MS plugged in when not in use, who am I with my limited engineering knowledge of a Tesla Battery to do something different. Also, I think sometimes enthusiasts can overthink things -- I sure do some times -- but in this case, I believe the KISS method (Keep It Simple Stupid) approach is best for me. I don't plan to keep my MS for the rest of my life, but I do expect that my battery range, especially with the 8-year warranty my MS battery has, will not be a problem as long as I own it, and likely not for whoever owns my best toy after me.
