DC Fast Charging Tips

Follow the 80% Rule - Since car battery follows what's called a "charging curve" when charging. Charging starts slow while your car monitors several factors, climbs to peak speeds for as long as possible and slows down again around 80% to prolong battery life. So it's best to unplug when your battery reaches about 80% charge. That's when charging slows dramatically—it could take almost as long to fill the last 20% of charge as it did to get to 80% in the first place.
