Charging it for less in Maryland
- An off-peak or dedicated EV rate is the single largest lever, and it costs nothing but a schedule set in the car. Utilities in high-rate states often price overnight power at a fraction of the average shown here.
- Cold weather cuts real-world efficiency substantially, sometimes by a third. Preconditioning while still plugged in draws from the wall instead of the battery.
- Public DC fast charging typically costs several times home charging. The figures on this page are home Level 2 only.
- Charging to 80% rather than 100% for daily use costs proportionally less per session and is easier on the pack.
