Charging an electric vehicle (EV) is simple, cost-effective, and convenient. You can charge at home, work, or while running errands – similar to charging your phone overnight.

Charging Speed Basics

Three main factors determine charging speed:

  • Your EV's cord capacity
  • Charging equipment power level
  • Ambient temperature

For optimal battery life, charge between 30% and 80% capacity.

Charging Levels Explained

Level 1:

  • Uses standard 120V household outlet
  • Comes with most new EVs
  • Perfect for overnight charging
  • Charges about 40 miles per night

Level 2:

  • Uses 208-240V outlet (like dryer outlet)
  • Available at homes and public locations
  • Charges 40 miles in under 2 hours
  • Requires professional installation at home

DC Fast Charging:

  • Provides 10-20 miles range per minute
  • Available only at public stations
  • Not for home use
  • Most modern EVs are compatible

Charging Costs

Home Charging:

  • National average: 13 cents per kWh
  • Full charge cost (80kWh battery): ~$10.40

Best Charging Practices

  1. Start charging at 30% battery level
  2. Charge to 80% instead of 100%
  3. Unplug from public chargers when done
  4. Use adapters carefully
  5. Follow charging station etiquette

Finding Charging Stations

  • Public stations are available at malls, stores, theaters, hotels
  • One charger for every 15 gas stations nationally
  • Many apps and websites help locate charging stations
  • Workplace charging increasingly available
  • Home charging possible for most residences

Battery Care Tips

  • Typical EV battery lasts 12+ years
  • Avoid completely depleting battery
  • Don't regularly charge to 100%
  • Use regenerative braking
  • Follow manufacturer guidelines

Additional Resources

  • Check with manufacturer for specific charging requirements
  • Consider installing Level 2 home charging
  • Look for local charging incentives
  • Join charging networks for convenience
  • Use charging station locator apps
