What does it actually cost to charge your EV at home in Maryland? We break down the math using current BGE and Pepco electricity rates.
The Math: BGE Residential Rate
As of 2025, BGE's standard residential electricity rate is approximately $0.13–$0.15 per kWh. A typical long-range EV (75 kWh battery) costs about $10–$11 to charge from empty to full on a BGE standard rate. For a driver who adds 1,000 miles per month (roughly typical), that's about $35–$45 per month in home charging costs, assuming 3–4 miles per kWh efficiency.
Time-of-Use Rates: Save More
BGE offers time-of-use (TOU) rate plans where off-peak electricity (typically 9pm–7am) costs significantly less — sometimes $0.07–$0.09/kWh. Smart chargers that schedule overnight charging can cut your EV electricity cost by 30–40% compared to the standard rate. Over a year, that's $100–$150 in savings for an average driver.
vs. Public Charging in Maryland
Public DC fast charging in Maryland (at Electrify America, ChargePoint, or EVgo stations) typically runs $0.35–$0.55 per kWh — three to four times the home rate. A full charge at a DC fast charger for a long-range EV costs $25–$40. Relying on public charging instead of home charging adds $200–$400 per year in costs for a typical Maryland driver.
vs. Gasoline
A comparable 30 MPG gasoline vehicle driving 1,000 miles per month uses about 33 gallons of gas. At $3.20/gallon (current Maryland average), that's $106/month in fuel. Compare to $35–$45/month for the equivalent EV on home charging. The annual savings are $700–$850 per year — or about the cost of a Level 2 charger installation after rebates. Most EV owners recoup their home charger installation cost through fuel savings within the first year.
