It can take 10 to 12 hours to fully charge an electric vehicle with Level 1 charging. You can charge your car three to four times faster by installing a 240-volt, Level 2 charger. Although your home probably has 240-volt service for a clothes dryer or electric range, you'll need a dedicated circuit for your EV charger. Don't install it yourself; hire a licensed electrician. Level 2 charging stations cost anywhere from $500 to $2,000, before incentives.
