I'm trying to figure out how often I should charge my MME. I've searched online, and I can't seem to find a clear answer to this question. Is it better for the battery to top off every night, or is it better to run it down (not all the way, obviously) to a lower percentage and just charge it at longer intervals?
I purchased my MME on the 13th, charged it when I got home (~80 miles of driving from the dealership to home). I have level 2 charging at home, so it charged just fine overnight. I did charge it to 100% that night, but I have since updated the car to only charge to 90%, per Ford's recommendation. Since that charge, I did slightly more than my typical driving, and didn't charge it again until last night (8 days of driving), and I was at around ~33% battery charge. So, I can clearly get away with a week of driving in most circumstances without charging and not have any issues.
Obviously, my mileage right now is a bit lower due to COVID, but my regular mileage is basically taking my kid to daycare M-F (~7 miles roundtrip), and maybe a few errands over the weekend. Even pre-pandemic, my loop between daycare, work, and home was only 17-18 miles, and I was fortunate enough to be able to work from home 2 days a week, so I was looking at ~65 miles per week (M-F).
Now, I get that I won't get the cabin pre-conditioning if I don't plug in every night, but since I live in Southern California, and my car is parked in a garage most of the time, the interior doesn't really hit either extreme when I'm at home. Also, my wife still has a gas car, so, in emergency circumstances, we still can make a long drive if the MME is low on charge.
So, back to the original question, given my typical driving habits, is it better for me to charge every night, or should I charge when I need to (mostly weekly, aside from planned longer drives)? Does either method affect the longevity of the battery either way?
