Methodology & Energy Data Sources — EV Charger (Level 2)
Source reviewed May 25, 2026: EIA rate feed, DOE Energy Saver guidance, ENERGY STAR criteria, and appliance-specific assumptions.
How we calculate EV Charger (Level 2) energy costs: Our calculations use EIA (US Energy Information Administration) residential electricity price data, cross-referenced with ENERGY STAR appliance efficiency standards and DOE Appliance and Equipment Standards. Wattage values reflect nameplate ratings from manufacturer specifications, normalized by the ENERGY STAR Testing & Certification Program.
- Wattage (7200W): Nameplate wattage from ENERGY STAR certified product database. Actual consumption may vary ±15% based on usage patterns and age of appliance.
- Annual kWh (6480 kWh): Calculated as (Wattage x Avg Hours/Day x Avg Days/Year) / 1,000. Usage hours based on RECS (Residential Energy Consumption Survey) typical usage patterns for Garage equipment.
- Annual cost ($1203): Calculated using the live EIA 2026-03 U.S. residential average electricity rate of 18.56¢/kWh. State-level rates are loaded from the same EIA data feed.
- Lifetime energy cost ($18,045): Projects 6480 kWh/year × 15-year lifespan at the current national average rate. Use the state selector for a local-rate version.
- Carbon footprint (4.63 metric tons CO2e/year): Uses EPA eGRID national average emission factors. Regional factors vary significantly, so check EPA eGRID subregion data for local estimates.
- EIA Electric Power Monthly — residential electricity rates
- EIA Residential Energy Consumption Survey (RECS)
- ENERGY STAR Certified Products Database
- EPA eGRID — electricity emission factors
- DOE Appliance and Equipment Standards Program
Disclaimer: Energy cost estimates are based on national and state averages. Actual costs depend on your utility's rate structure, time-of-use pricing, demand charges, and actual usage patterns. Contact your utility for exact rates and consider a home energy audit for personalized recommendations.
