AC/DC fast charging stations are comprehensive charging facilities that support both alternating current (AC) and direct current (DC) charging, catering to the charging needs of different types of electric vehicles. Here is the working principle:

Alternating Current (AC) Charging: The charging station is connected to an AC power source, typically the grid or another AC power supply. The charging station converts AC power into the appropriate form of energy for electric vehicle charging.

Direct Current (DC) Charging: Fast charging stations are equipped with DC charging modules that convert AC power into direct current to meet the requirements of vehicles that need DC charging.

Charging Control: Charging stations are equipped with charging control units responsible for monitoring and managing the charging process. They regulate the charging power and current to ensure safe and efficient charging.

Charging Interface: Standardized charging interfaces are installed on the charging stations, allowing them to connect with the charging plugs of electric vehicles. Through this connection between the plug and the charging interface, energy is transmitted to the vehicle's battery for charging.

Charging Protection: Charging stations incorporate various safety measures to ensure the safety of the charging process. These measures may include overcurrent protection, overvoltage protection, temperature monitoring, and power outage protection, among others.

By combining AC and DC charging technologies, AC/DC fast charging stations provide flexible, efficient, and safe charging services for electric vehicles. Whether it is a vehicle that supports AC charging or one that requires DC fast charging, the charging stations can meet their diverse charging needs.
