Control pilot

The signal wire in an AC or CCS charging connector: the charger puts a ±12 V square wave on it whose duty cycle tells the vehicle the maximum current, and the vehicle answers by switching resistors. The proximity pilot beside it tells the vehicle a plug is inserted.

Abbreviation
CP
Also called
proximity pilot, PP

Example

Charging infrastructure: an example situation

A 100 kW model request does not establish real voltage, current, connector or negotiation compatibility.

Read Control pilot alongside Charging control unit in this context. The vehicle-side controller that manages charging: it detects the plug, talks to the charging station over the control pilot or ISO 15118 and DIN 70121, and passes the current and voltage limits the BMS allows. In some bus and truck architectures CCU also names a central or cluster control unit, so the system diagram decides.

Use in Lemonergy

Separate compatibility from requested average power.

This is a reference concept. No executable Lemonergy block has been verified for this term.
