Level 1
Level 1 charging is the slowest form of charging and can be obtained by connecting an EV to a standard household outlet. This is an uncommon form of charging for fleets and is recommended for those fleets that travel 40 miles at most daily.
Level 2
Level 2 charging is the most common type for fleets and can occur at home or at a depot. For most applications, adding chargers to home-based depots will be essential. Level 2 Charging requires a 240-volt at-home outlet (such as the outlet often used for dryers and refrigerators) and a specialized EVSE "box" that becomes the intermediary between the power source and the car. The EVSE costs around $1,200 and adds 10 to 60 miles of range per charge hour.
Level 3
Level 3 charging is the fastest and most expensive method. The charger is roughly the size of a gas pump and is found in public. Drawing 480-volt, Level 3 chargers provide about 90 miles of range in approximately 30 minutes and are ideal for heavy-duty trucks. Most fleets do not need to consider Level 3 Charging due to the incredible expense involved.
