A DC charging station performs offboard power conversion and supplies controlled DC to the vehicle interface.

## In plain English

### What does DC electric vehicle charging station mean?

A DC charging station performs offboard power conversion and supplies controlled DC to the vehicle interface.

### A simple example

The station coordinates the requested voltage and current with the connected vehicle.

### What the drawings help you do

Show the grid-side conversion stages, controlled DC output and vehicle communication separately. The station performs offboard conversion; its cable and connector deliver the resulting DC interface. A site drawing also needs the selected cabinets, auxiliaries and installation interfaces beyond this functional overview.

### Before using this reference

- Separate AC input, conversion and DC output paths.
- Identify the vehicle-control and measurement interfaces.
- Reference the exact power modules, connector and installation documents.

### Is a DC station just an AC charge point with another connector?

No. The power-conversion location and control arrangement differ. A DC station includes offboard conversion that regulates the DC supplied to the compatible vehicle interface.

### Terms

- Offboard: Equipment located outside the vehicle.
- DC output: The controlled direct-current supply presented by the selected charging system.
