Different vehicles charge at different speeds, so these recharge times are just estimates.2
Level 1 uses a regular household outlet, but recharging is fairly slow, adding on average about 2 to 3 miles of range per hour.
Level 2 uses a 240-volt connection, such as you may have for a large appliance. You can install a connection at home, but you'll need a place to put it, such as a garage or parking spot. These chargers add 12 to 37 miles of range per hour, so you can get a full recharge overnight (or during the workday if your employer offers a charging option).
Level 3 DC fast chargers are located at many public charging stations and are becoming more and more available. Level 3 chargers can add dozens if not hundreds of miles in as little as 30 minutes.
