Frequently Asked Questions
How long does it take to charge an EV at home?
On Level 1 (120V outlet), a full charge can take 40-60 hours. On Level 2 (240V/7.2kW), most EVs charge in 8-12 hours. Most people plug in overnight and wake up to a full charge with Level 2.
How much does it cost to charge an EV?
At the national average of $0.13/kWh, charging a 75 kWh battery costs about $9.75 for a full charge, giving roughly 250-300 miles of range. This is equivalent to about $0.03-0.04 per mile.
Is Level 1 or Level 2 charging better?
Level 2 is strongly recommended for home EV charging. It charges 5-6x faster than Level 1, easily providing a full charge overnight. Level 2 requires a 240V outlet and an EVSE (charger), typically costing $300-$800 installed.
