    Frequently Asked Questions

    How much does it cost to charge an EV?

    Home charging typically costs $0.10-$0.20 per kWh. For a 75 kWh battery charging from 20% to 80%, expect $6-$9 at home or $16-$22 at public stations.

    Is home charging cheaper than public?

    Yes, home charging is typically 50-70% cheaper than public fast charging, depending on your local electricity rates and the public charger pricing.

    What affects EV charging efficiency?

    Charging efficiency (typically 85-95%) is affected by temperature, charging speed, battery condition, and the charger type. L2 chargers are more efficient than L3 fast chargers.

    How many miles do I get per kWh?

    Most EVs achieve 3-4 miles per kWh. Smaller EVs can reach 5+, while larger trucks/SUVs may get 2-3 miles per kWh.

    Should I charge to 100% every time?

    For daily driving, charge to 80-90% to preserve battery health. Charge to 100% only for long trips, as frequent full charging accelerates battery degradation.

    How do electricity rates affect charging costs?

    Rates vary by location and time of day. Time-of-use plans offer lower rates overnight (as low as $0.08/kWh), making off-peak charging much cheaper.

    What is the cost difference between Level 2 and DC fast charging?

    Level 2 charging costs $0.10-$0.20/kWh at home. DC fast charging costs $0.30-$0.60/kWh. Fast charging is convenient but significantly more expensive.

    How do I reduce EV charging costs?

    Charge at home during off-peak hours, use solar panels, maintain proper tire pressure, drive efficiently, and minimize DC fast charging.
