Frequently asked questions

Is it cheaper to charge at home or DC fast?

Home Level 2 is 3–5× cheaper per kWh than public DC fast on national 2026 averages (home $0.175, DC fast $0.48). Exceptions: TOU off-peak (some utilities $0.04–0.08/kWh between 11 PM and 6 AM) and free workplace charging.

How many kWh per mile does an EV use?

Sedans 0.24–0.28, midsize SUVs 0.30–0.34, pickups 0.42–0.50. Cold weather adds 15–35 % to consumption.

Should I install Level 2 charging at home?

Yes if you drive over 30 mi/day. Hardware $400–$700, install $800–$2,500. Federal Section 30C credit (30%, capped at $1,000 residential) was eliminated July 2025 by OBBBA; some utilities still rebate.
