Frequently asked questions
No, EV connectors are not universal. The plugs vary by type, charging speed, and compatibility. For example, the J1772 plug is the most common, but Tesla’s are not able to use it without an adapter. Not all EVs are compatible with Level 3 fast chargers because of high voltage.
Level 1 and 2 chargers convert AC to DC to power your EV’s battery. A 120-volt household outlet can be used for Level 1 chargers, but you may need a professional to install a 240-volt outlet for Level 2 chargers. Level 3 chargers use DC to directly charge the battery without needing a current conversion and are not available for residential use.
The U.S. Department of Energy provides a map for locating EV charging stations throughout the U.S. and Canada. The map provides a filtering option, so you can make a selection and find stations using the connector needed for your EV. The cost to charge an EV varies based on location, charger type, and other factors.
Charging speed depends on the EV battery size and EV charger type. Level 1 chargers can take about 40 to 50 hours to charge an EV fully. Level 2 chargers can take about 4 to 10 hours, and Level 3 takes 20 minutes to an hour for a full charge.
