What is Level 1, Level 2, and Level 3 (DC Fast) charging?
Level 1 uses a standard 120V household outlet and delivers 3–5 miles of range per hour. It's the slowest method but requires no special equipment — just plug in at home.
Level 2 uses a 240V circuit (like a dryer outlet) and delivers 15–30 miles of range per hour. Most home EV chargers and public destination chargers are Level 2.
Level 3 (DC Fast Charging) bypasses the car's onboard charger and delivers power directly to the battery. Speeds range from 50 kW to 350 kW, adding 100–200+ miles of range in 20–40 minutes. Tesla Superchargers, Electrify America, and EVgo are primarily DC fast charging networks.

How much does it cost to charge an EV?
Charging costs vary widely depending on the network, your location, and the time of day.
Home charging: Typically $0.09–$0.37/kWh depending on your state's electricity rates. Charging a 75 kWh battery from empty to full costs roughly $7–$28 at home.
Public Level 2: Often $0.20–$0.45/kWh, or a flat hourly rate of $1–$3/hour.
DC Fast Charging: Usually $0.25–$0.60/kWh. A 20–30 minute fast charge to add 100 miles typically costs $8–$20 depending on the network and your vehicle's efficiency.

Tesla Supercharger vs Electrify America — which is cheaper?
It depends on your membership status and location.
Tesla Supercharger rates average $0.25–$0.50/kWh for non-members. Tesla owners who charge regularly can reduce costs through billing tiers.
Electrify America charges $0.43–$0.48/kWh for pay-as-you-go users, but the EA Pass+ membership ($4/month) drops this to $0.25–$0.32/kWh — often making it cheaper than Superchargers for frequent users.
For occasional road trips, Tesla Superchargers tend to have better reliability and more locations. For cost-conscious drivers with an EA Pass+, Electrify America can be the better value.

How do I calculate cost per mile for EV charging?
Use this formula:
Example: You drive a Tesla Model 3 Long Range (75 kWh, 358-mile range) and pay $0.13/kWh at home:
(0.13 × 75) ÷ 358 = $0.027 per mile (~2.7 cents/mile)
At a public fast charger at $0.45/kWh:
(0.45 × 75) ÷ 358 = $0.094 per mile (~9.4 cents/mile)
Use our Cost Calculator to run these numbers for your specific vehicle and network.
(kWh rate × battery size) ÷ range = cost per mileExample: You drive a Tesla Model 3 Long Range (75 kWh, 358-mile range) and pay $0.13/kWh at home:

Is home charging cheaper than public charging?
Almost always yes — by a significant margin.
Home charging costs typically range from $0.09 to $0.37/kWh depending on your state. Even in high-rate states like California (~$0.29/kWh), home charging is usually 30–60% cheaper than public DC fast charging.
The exception: some workplaces offer free Level 2 charging, and a few networks (like Volta) offer ad-supported free charging at retail locations.
For most EV owners who can charge at home, 80–90% of their charging happens overnight at home rates. Public fast charging is mainly for long road trips.

How long does it take to charge an EV?
Charging time depends on three factors: charger speed (kW), your battery size (kWh), and your car's maximum charge rate acceptance.
Level 1 (1.2–1.4 kW): 40–50+ hours for a full charge — practical only for top-ups overnight.
Level 2 (7–19 kW): 4–12 hours for a full charge. Most home setups and workplace chargers.
DC Fast Charging (50–350 kW): 20–60 minutes to reach 80%. (Charging slows above 80% to protect battery.)
Example: A Tesla Model Y (75 kWh battery, 250 kW max charge rate) at a 250 kW Supercharger can add 200 miles in about 25 minutes.

What is kWh and why does it matter for EV charging?
A kilowatt-hour (kWh) is the standard unit of electrical energy — equivalent to using 1,000 watts of power for one hour.
For EV charging, kWh matters in two ways:
Battery size: EV batteries are rated in kWh (e.g., a 75 kWh battery). A larger battery = more range, but also means a longer or more expensive charge.
Charging cost: Most public networks charge per kWh (e.g., $0.35/kWh). Some charge per minute instead — which can be more expensive if your car charges slowly.
Why per-kWh pricing is better for consumers: You pay for actual energy delivered, regardless of how fast your car charges. Per-minute pricing can penalize owners of vehicles with slower onboard chargers.
