What is DC charging?

DC in DC charging is direct current, it is typically used for fast charging of electric vehicles, and stored in batteries of portable electronic devices (e.g. mobile phones, electric vehicles).
Fast chargers for electric vehicles make use of DC charging. They convert the power before it enters the vehicle and after conversion, the power goes directly into the car battery, bypassing the car’s converter.

There is a wide range of DC charge point types, ranging from 25 to 400 kW. A DC charge point typically requires more power from the grid than an AC charge point (up to 580A). Therefore the costs (production, installation and operation) are quite high, resulting in higher tariffs for charging. However, as it usually allows for much faster charging, it is the preferred charging method to quickly recharge during long-distance trips (for cars that support DC charging). This type of charger is mostly found along highways, rather than at home or business locations.
