Arrangement and method for locking an automatic reeling mechanism of a charging cable for an electric vehicle

摘要

An automatic reeling mechanism for an electric vehicle or a charging post can automatically reel a charging cable and thus protect it against dirt and weather. In order to reduce mechanical loads and damage to the plug and minimize a risk for stumbling to a person, the automatic reeling mechanism is switched in a passive mode as long as a plug of the charging cable is plugged in and is not touched by a person. This is the case during the charging process. In this way, the automatic reeling mechanism can be comfortably used because no traction forces are active during the charging process and the charging cable can be laid out so that there is no risk of stumbling.

主权项

1. A device for a charging cable having a plug to be inserted in an electric vehicle or in a charging station, comprising:
an automatic reeling mechanism to automatically reel the charging cable such that the charging cable can be drawn out of the automatic reeling mechanism by overcoming a retraction force which acts on the plug of the charging cable via the charging cable; and a control unit to:
detect whether the plug of the charging cable is inserted or is no longer being touched by an operator, andat least reduce the retraction force as soon as the plug of the charging cable is inserted or is no longer being touched by the operator.
