EV chargers are classified into three categories: Level 1, Level 2, and direct current (DC) fast charging. Sometimes DC charging or fast charging is also referred to as level 3 charging. Do you know what is Level 1, 2, 3 Charging? Or what are the major differences between them?
Level 1 Charging
Level 1 charging is the slowest way to charge an electric vehicle. So it is mainly used for home charging. The maximum output for Level 1 charging stations is between 1.3 kW to 2.4 kW, which adds about 3.5 – 6.5 miles of driving range per hour of charging. These charging rates can be satisfactory for drivers who do not drive more than 30-40 miles daily and who can use the charger overnight.
Level 1 works well at home, work, or anywhere—when you have sufficient time to charge. This charging takes the longest and is used primarily as an additional, emergency, or backup charging solution.
Level 2 Charging
Level 2 charging is considerably faster, but requires installing charging stations. They are typical solutions for residential and commercial/workplace settings. Level 2 charging station installation requires a dedicated 240-volt or 208-volt electrical circuit. Besides, Level 2 chargers use the same standard connector as Level 1 charging, meaning any electric car can plug in at any Level 2 charger.
In general, Level 2 chargers are distinguished between non-networked chargers and networked chargers.
Level 3 charging - DC Fast Charging
Direct current fast charging is the fastest way to fill up an EV. A DC EV charger can boost the EV battery to 80% within 30 minutes based on battery pack size. However, since it requires a 480-volt connection, making DC fast charging is unsuitable for home use, and not every electric car model is equipped for it. Level 3 DC fast charger is the ideal charging type for on-the-go locations like shopping centers, gas stations, or fleet depots.
