Which level of Electric Vehicle (EV) charger is designed solely for public charging?

Level 3 chargers, often referred to as DC fast chargers, are specifically designed for public charging of electric vehicles. These chargers enable rapid charging, typically delivering significant amounts of power (in the range of 50 kW and higher), significantly reducing the amount of time it takes to recharge an electric vehicle compared to Level 1 and Level 2 chargers.

Level 1 and Level 2 chargers are primarily intended for use in residential or commercial settings rather than public charging stations. Level 1 chargers use a standard 120V outlet, which makes them slow and suitable for home use where vehicles can be charged overnight. Level 2 chargers, while also common in both home and public settings, usually provide faster charging than Level 1 but are still not as rapid as Level 3. They typically operate at 240V and serve both residential and commercial applications, making them versatile but not solely designated for public use.

Level 4 is not a commonly recognized standard in electric vehicle charging. The existing levels are primarily categorized into Level 1, Level 2, and Level 3, focusing on power output and charging speed. Therefore, when discussing chargers specifically designed for public use with high-speed capabilities, Level 3 is identified as the correct choice.
