Abstract
A method for checking a control pilot, referred to below as CP, line of a charging socket of an electrically drivable transportation means. The method includes closing the charging socket, as a result of which an electrical, in particular galvanic, connection is closed between the CP line and a line of the charging socket providing electrical energy, and checking a signal received via the CP line in response to the closing. Also disclosed is a corresponding apparatus.
Claims9
A method for checking a control pilot (CP) line of a charging socket of an electrically drivable vehicle, the method comprising:
- closing the charging socket, as a result of which a galvanic connection is closed between the CP line and a line of the charging socket which provides a signal to the CP line;
- and
- checking the signal received via the CP line in response to the closing using an evaluation unit,
- wherein closing the charging socket prevents contact with charging infrastructure.
An apparatus for checking a control pilot (CP) line of a charging socket of an electrically drivable vehicle, the apparatus comprising:
- at least part of a CP line;
- a line which provides electrical energy and ends in the charging socket;
- and
- an evaluation unit,
- wherein the evaluation unit is designed to check a signal of the line which provides electrical energy which is received via the CP line in the evaluation unit when the charging socket is closed,
- wherein when the charging socket is closed it is prevented from contacting charging infrastructure, and
- wherein the line which provides electrical energy is a plug present (PP) signal line.
An electrically drivable vehicle comprising an apparatus for checking a control pilot (CP) line of a charging socket of the electrically drivable vehicle, the apparatus comprising:
- at least part of the CP line;
- a line which provides electrical energy and ends in the charging socket;
- and
- an evaluation unit,
- wherein the evaluation unit is designed to check a signal of the line providing electrical energy which is received via the CP line when the charging socket is closed, and
- wherein when the charging socket is closed it is prevented from contacting charging infrastructure.
