How to use the Level 1 vs Level 2 EV Charging Time
The Formula
Hours = kWh ÷ kW (ignoring losses). Level 1 (~1.4 kW) is slow overnight; Level 2 (6–11 kW) suits daily top-ups.
Practical Example
If you drive under ~40 miles/day, Level 1 may suffice. Higher mileage or large packs benefit from a 240 V Level 2 circuit.
