There are three primary levels of EV charging:
Level 1 Charging: Uses a regular household outlet (120 volts). It's the slowest form and is typically used for overnight charging at home.
Level 2 Charging: Requires a specialized charging station and provides power from a 240-volt source. It's commonly found in public places and can charge a typical EV in four to eight hours.
DC Fast Charging: Offers rapid charging, often charging an EV to 80% in under an hour. However, compatibility varies. For instance, Tesla's Supercharger stations, which utilize this fast-charging technology, are primarily for Tesla vehicles, though there have been discussions about opening them up to other EVs.
