I have a 60kWh battery and commute 75 miles round trip daily. There is a new Clipper Creek, 16 amp/10 MPH charger at work and I have been using it. With my range, I could charge every other day, but all charging would be at home, or I can charge every day, either at home or the charger or I can charge at home and "top off" daily at the freeby charger. Would the twice a day charging hurt (or help) the battery? (I don't do full charges.)
