Has anyone done or could help with this analysis? What is the fastest speed we should use on m3 to get somewhere far (1000+ miles) while using only superchargers to charge up in order to get somewhere in the shortest amount of time? I.e. driving 90 mph in m3, battery loses about 30% so it takes 150 miles of charge to go 100 miles. Then it takes ~20 mins to charge those 150 miles of battery. So in effect, you spend ~85 minutes to go 100 miles which averages to ~70 mph (drive+charge) speed. Eg 65 minutes to drive 100 miles and 20 minutes to charge= 85 minutes to travel 100 miles. What happens when's driving 80, 70, 60 instead of 90?
