I have had my 90D for 5 weeks now. I have read many different threads on here about charging percentages and how low to let the battery get, etc., and there seems to be a wide array of opinions. I'd appreciate any clarifications or thoughts, mainly about whether the differences in opinion are actually significant in terms of battery health or whether they are personal preferences.
Daily Charging Percentage: I have seen 50%, 80%, 90%. I've been doing 80%, but does it really matter, as long as it's not 100%?
Charging to 100%: I've seen that you should only do this if you will be driving "right away". What timeframe is this? Within 10 minutes? 2 hours? I have done this once to go on a 250 mile trip, but set it to charge the night before. Should I be changing the charge start time to try to anticipate it finishing closer to when I will actually leave?
Lowest SOC: I've seen not to let the battery get below 10%. I've also seen to arrive at a Supercharger with as little charge as possible. On my one long trip, we didn't make it as far as I had thought we would. We left home with 292 rated miles, but rain, wind, new tires, and inconsistent driving speed (my 19 year old son was driving) all meant we had to pull into an SC at 212 miles with around 6% charge. We charged enough to get to our destination (my son's college) and for me to get back to the SC. On my way home, I charged to 85% and the system said I'd arrive home with 5%. I was able to finagle things to actually get home with 13%. I really didn't want to have to make a second SC stop on the way. So, what's the ideal lowest percentage?
Range Mode: I've seen some people say to use it on long trips and other people say not to use it. I'm not sure what to think. I forgot to turn it on on the way to the college, but did turn it on on the way back. I'm assuming that contributed to the change in range.
Preheating: I live in Berkeley, CA, so it doesn't get super cold here very often. For daily driving, I don't think it matters to preheat the car/battery, but is it better for the health of the battery? What about on a full range trip?
Plugging In: I'm trying to keep the car plugged in all the time at home. There have been a few times when it has gone a day not plugged in. The cable has to go across the path my husband uses to get into the house and it is a minor inconvenience in his wheelchair. My impression is that it's not an issue for shorter periods, but is for longer. I don't expect to need to leave it unplugged for lengthy periods, but how long can it go without damaging the battery?
Anything else I should know? Thanks!
