I know that there are other charging routine questions, but I wasn't sure if my situation is unique at all. I have a 14-50 NEMA plug in my garage, but I can also charge at work. At work, they just charge me a flat rate of $12/month regardless of what I consume. I have the charge limit set to around 75% now. Given my and my wife's driving, I could easily charge it up on Monday, have her drive it Tues, Wed, and Thurs, and then I can charge it back up on Friday. Due to the flat rate, I have no motivation to plug in at home unless I have some trip coming up. But am I going to be getting more degradation from doing this? I've read the manual, and I know that a plugged in Tesla is a happy Tesla. But to save the most costs, I'd rather not plug in at home...really ever at all.
