I've seen a few comments about leaving your car plugged in everyday for maximum battery happiness, but what's the recommendation for if you have a very short commute? I use to drive 35 miles a day, but for the past 6 months my commute has become 6 miles round trip. Prior (with the longer commute) I had my car set to charge to 75% and noticed that my 100 and 90% charges were very low (165-171 miles for a 60kwh battery). The service center had me set my charge to 90% over 2 months ago to help balance the battery, but it is not increasing. So my question is in this scenario where I don't use much battery on a daily basis is it better to leave the car unplugged until I burn 30-60% and then charge back up or just charge back the 3-6% I burn up daily? Thoughts???
