What is an AC EV charger and what is a DC EV charger?

An AC EV charger (alternating current) and a DC EV charger (direct current) play a crucial role in electromobility by charging electric vehicles and thus improving their range and availability. Let's start with the AC EV charger.

The AC EV charger, which relies on alternating current, is an essential element for charging electric vehicles, be it at home or at public charging stations. These chargers act as a link between the electrical grid and the electric vehicle by converting the alternating current from the socket into direct current suitable for the vehicle's battery. Using AC EV chargers offers electric vehicle owners a convenient way to charge their vehicles overnight, making them ready for their daily commutes. They also contribute to the flexibility to charge electric vehicles at public charging stations during the day, which is particularly advantageous in urban areas.

On the other hand, we have the DC EV charger, which acts as a fast charging system and uses direct current to charge electric vehicles in the shortest possible time. These chargers are typically found at fast charging stations and offer significantly higher charging power compared to AC EV chargers. Providing direct current to the vehicle enables faster charging speeds, which is particularly advantageous on long journeys or when there is an urgent need for energy. DC EV chargers therefore play a crucial role in providing charging options along highways and in busy urban areas where fast charging is of great importance.

Overall, AC EV chargers and DC EV chargers work together to support electric vehicle infrastructure and drive electric mobility adoption. While AC chargers provide the basis for everyday charging, DC chargers enable quick charging on the go, making electric vehicles an increasingly attractive option for drivers and thus helping to reduce the environmental impact of road transport.
