Alternate (AC) and direct (DC) charging are two different charging modes used to power electric vehicles.
AC charging is the most common charging method for electric vehicles. Electricity is supplied from the home grid or public charging stations via AC sockets and cables during charging. The energy is converted from AC to DC via a conversion device called an onboard charger in the vehicle.
Direct current (DC) charging is a faster charging method than AC charging. In this case, electricity is supplied by specially designed charging stations with internal conversion devices to convert energy from DC to high-voltage DC. During DC charging, the power is sent directly to the electric vehicle battery without going through an onboard charger. This allows electric vehicle batteries to be recharged in a much shorter time than AC charging.
