Charging an Electric Vehicle: A Complete Guide to Speed, Cost, and Convenience
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
