BMW i7 fast charging
DC fast charging bypasses the car's onboard charger and is far quicker, but the speed depends on each model's charging curve, which slows as the battery fills. That's why fast-charge times are quoted from 10% to 80%. The EPA doesn't test DC charging, so check BMW's quoted figure for the i7. The EV charging curve guide explains why it slows.
