I am a new owner for Model X 100D. I only have access to a 100V plug in my apartment building and can't install better options. My town does have a Supercharger. I heard that ONLY Supercharging can be bad for the battery. I am also trying to maintain it between 30-80%. I just plugged my car into the 110 outlet for the first time. Started off at 113 miles, which would be 38% on the "295" range. I can charge it for about 15 hours before having to take it to work. It is charging at 2 miles per hour, so it should put me around 143 miles (48%). Then I have to drive and will probably lose 10 miles making it around 133 miles (45%). Then charge again and use again.

Will doing little charges like these of about 10% a day and using lets say 5% mess with the battery?? I would be fluctuating between 10-15% charge and use without actually reaching my goal of 80% charge before I have to drive again. Or are these small charges and uses a bad idea?? Thanks
