The charging speeds offered by various EVSE variants vary. Chargers at level 1 use a 120 volt (V),
5 miles of range are provided for every hour of charging via an alternating-current (AC) socket and a dedicated circuit.
Level 2 stations use a 240V, AC plug to charge
and demand the installation of home charging or public charging devices.
For every hour of charging at a level 2 station, 10 to 20 miles of range are provided.
The most popular chargers, Level 2 chargers, charge roughly at the same rate as a residential system.
DC fast chargers are another name for level 3 chargers.
A 480V direct-current (DC) socket is used for Level 3. They don't use the in-car charger.
