The increasing number of Electric Vehicles (EVs) on the roads brought about the need for more charging stations, including DC fast charging stations and CHAdeMO-compliant fast charging stations. DC fast charging stations provide vehicles with level-3 charging, enabling a 100-kilometer driving range in just 10 to 12 minutes. While level-2 chargers supply AC power to the battery (which is then converted to DC power by the on-board charger), level-3 fast chargers directly deliver DC power, which significantly improves charging time. DC charging stations currently target three main power levels: ≤ 50 kW for city use, 150 kW for highways, and 350 kW for supercars/trucks/buses. DC fast chargers usually include 20 kW subunits and then stack them up to create a higher power DC charging system. The ≤ 50kW power level category for city use shows the biggest growth according to market studies.
