EV control pilot interface
In plain English
What does EV control pilot interface mean?
The control pilot is part of the signalling interface between charging equipment and a vehicle.
A simple example
Charging equipment can use pilot signalling to coordinate a permitted charging state.
What the drawings help you do
Show the pilot connection beside, but separate from, the charging power conductors. It carries interface information used in the charging sequence. Label the charger side and vehicle side, and refer to the selected charging-system documentation for the applicable signal interpretation.
- Pilot
- A signalling connection used by the selected charging interface.
- Power conductor
- A conductor intended to carry the charging energy.
Before using this reference
- Identify which side is the charge point and which is the vehicle.
- Keep pilot wiring separate from the main power path.
- Reference the applicable interface and fault-state requirements.
Does the pilot conductor deliver charging power?
No. Its role is signalling. The charging energy uses the designated power conductors, controlled by the complete charging system and its switching and protection arrangements.

A distinction that matters
A pilot signal is a control interface, not the main charging power conductor.
