Abstract

A charging device for an electric vehicle, which charging device can be protected against unauthorized access in a particularly reliable manner. The charging device for an electric vehicle has a bolt for locking a connection between the charging device and a further charging device. If the charging device is mechanically connected to a further charging device for charging purposes, this mechanical connection is then locked by a corresponding end of the bolt being moved into a retaining opening in the further charging device. A retaining opening of this kind can, for example, be damaged by a broken web which serves for locking such that locking is no longer possible. Therefore, a device is provided which can prevent movement of the bolt in the direction of a locking position when the retaining opening is damaged in this way. A locking arrangement which is damaged in the above manner therefore fundamentally does not remain unnoticed. Charging therefore preferably requires sufficiently undamaged, correct locking of the two charging devices involved.
