An AC charge point controls the AC supply and charging interface presented to a vehicle.

## In plain English

### What does AC electric vehicle charge point mean?

An AC charge point controls the AC supply and charging interface presented to a vehicle.

### A simple example

The vehicle's onboard charger performs the conversion needed to charge its battery from an AC connection.

### What the drawings help you do

Draw the AC power path, controlled switching and vehicle signalling as separate parts. In AC charging, the vehicle’s onboard charger performs the battery-side conversion. The charge point provides the controlled supply and interface; it should not be drawn as if it were an offboard DC converter.

### Before using this reference

- Identify supply phases and the selected connector arrangement.
- Separate pilot signalling from charging conductors.
- Reference the complete switching, metering and protection design.

### Where is AC converted for the vehicle battery?

In an AC charging arrangement, that conversion is performed by the vehicle’s onboard charging equipment. A DC charging station instead supplies controlled DC from offboard conversion equipment.

### Terms

- Onboard charger: The vehicle equipment that converts the incoming charging supply for its battery.
- Charge point: The supply and control interface presented to a vehicle.
