On average, Level 2 chargers can provide around 10-60 miles of range per hour, depending on the electric vehicle's battery capacity and charging capabilities.

These stations are commonly found in public places such as parking lots, shopping centers, and workplace parking areas. Level 2 charging can be an excellent choice for EV owners who need to top up their vehicles' batteries while going about their daily activities. With the charging rates provided, Level 2 stations can efficiently charge an electric vehicle in just a few hours.

Level 3 Charging Stations (DC Fast Charging)

Level 3 charging stations, also known as DC fast charging, are designed to deliver a rapid charge to electric vehicles. Unlike Level 1 and Level 2 stations, Level 3 chargers use direct current (DC) instead of alternating current (AC) to charge the vehicle's battery directly. This allows for significantly faster charging speeds.

Level 3 chargers can provide an impressive range of 60-80 miles in just 20 minutes of charging, making them ideal for long-distance travel or emergencies. However, it is important to note that not all electric vehicles support Level 3 charging. While most modern EVs are equipped with fast-charging capabilities, some older models may not be compatible with these stations.
