Source check: September 13, 2026. DOE's Alternative Fuels Data Center continues to distinguish Level 1 home charging from faster Level 2 charging and recommends code-compliant installation by qualified professionals. Charging cost depends on vehicle efficiency, wall losses and the applicable utility tariff, including time-of-use pricing where offered.
