L1 charging adds about 1 kWh to the battery for each full hour of charging. With freeway driving and climate control use, 3 miles per kWh is a reasonable energy consumption value. Therefore, 8 hours of charging is good for about 24 miles of driving. I prefer to round down when offering recommendations to make sure potential EV drivers understand the limitations of L1 charging.
