Level 1 charging stations are typically provided with an EV purchase and use a J1772 connector. They are rated 120 Volts and can be plugged into a standard NEMA 5-15 household outlet. Level 1 provides the slowest charging time, averaging 5 miles of range per hour of charging.
Level 2 charging stations are the most common type of charging stations in the US and North America, using a J1772 connector. As of 2022, over 85% of public EVSE ports in the US were Level 2. They are rated 240 Volts and charge faster than Level 1, averaging 25 miles of range per 1 hour of charging. Level 2 charging stations are common for homeowners, workplace, and other commercial/public locations.
DC charging stations, often referred to as "Level 3 Charging Stations", use direct-current to provide quick charging. They use CCS connectors (also known as J1772 combo) and CHAdeMO connectors. They are typically rated 208/480 Volts and charge faster than Level 2, averaging 100-200+ miles of range per 30 minutes of charging (or 200-400+ miles of range per 1 hour of charging) and are common at rest stops, gas stations, shopping malls, and other public locations.
