A charging contactor control function commands the switching device in the charging power path.

## In plain English

### What does EV charging contactor control mean?

A charging contactor control function commands the switching device in the charging power path.

### A simple example

A charging controller can close the selected contactor only when the required operating conditions are satisfied.

### What the drawings help you do

Draw the contactor coil command separately from the main contacts carrying charging power. If the design monitors contact position, show that feedback as another signal. This makes it clear that requesting a change and confirming the physical contact state are different parts of the control sequence.

### Before using this reference

- Identify the coil or actuator interface.
- Distinguish main contacts from auxiliary feedback contacts.
- Reference the selected charging sequence and interlocks.

### Does an ON command prove the contacts closed?

No. A command expresses the requested state. Any confirmation depends on the actual feedback arrangement and the checks implemented by the charging system.

### Terms

- Coil: The electrically operated part that actuates a contactor.
- Feedback contact: A separate contact used to report an associated mechanism’s condition.

## How to read it

- Identify the coil or actuator interface.
- Distinguish main contacts from auxiliary feedback contacts.
- Reference the selected charging sequence and interlocks.
- A control command does not itself verify that the contactor contacts reached the requested state.

## Information to show or reference

- Identify the coil or actuator interface.
- Distinguish main contacts from auxiliary feedback contacts.
- Reference the selected charging sequence and interlocks.

## Important distinction

A control command does not itself verify that the contactor contacts reached the requested state.
