BMW's qualifies a bad profile by somebody who drive less than 5km at a time. These short distances do not allow a battery to actually charge and you are using more power than charging. Where we live we are about 5 miles from most places we go. My last report was like 120 trips under 5km in 30 days. How did I Do that???? Drop off at daycare 3 (car odd)miles, from daycare to home 3 miles(car off) , to grade school after school 4 miles (car off), then home. That's 80 cycles for just school. If I go to lunch, 2 more short trips and throw in a drive to the grocery store, now were looking at 8-10 trips the burn the battery power than charge it.

The real killer is the heated seats, defrosters, A/C full blast on the short trips. I do take some 20-30 milers 1-2 times a week which helps but the cars still need the tender
