Embodiments of a method for monitoring a charging process at a charging station are provided herein. In the method, the end of a charging process with an electric vehicle at the charging station is determined. In order to determine whether a vehicle is permanently connected to a charging station, without charging, it is proposed to carry out a charging readiness test with the electric vehicle at the charging station after the end of the charging process with this electric vehicle has been determined and to produce a signal at the charging station when charging readiness has been determined.

Method and device for checking a connection between an electric vehicle and a charging station

Provided is a charging station for electric vehicles. The charging station includes a charge control circuit designed to control a charging process of an electric vehicle at the charging station, a communication module having a charge control interface designed for communication with the charge control circuit, and an operator interface designed for communication with a control centre external to the charging station. A first protocol is implemented in the operator interface for communication with the control centre. Improved interoperability is ensured by providing an interface device arranged at the operator interface in the charging station. This interface device communicates with the operator interface by means of the first protocol and with the external control centre by means of a second protocol which is different from the first protocol.

Charging station for electric vehicles as well as interface device in such a charging station and method for operating a charging station

A component with an internal conductor is so configured that it is ruptured at a predetermined position while forming an arc, if predetermined current/voltage conditions occur at the terminals of the component. The component includes a circuit element which is so arranged that an arc formed at the predetermined position can act on the circuit element such that the circuit element alters its electrical properties.

Self-configuring component by means of arcing

The invention relates to a method for producing a protective component, for example a fuse component or a fusing resistor, including a fusible element and a heating element, which are attached as stacking components to the surface of a substrate. The fusible element is configured in such a way that a current flow between its connections is interrupted, if the fusible component is heated, at least in one fusible region, for a predetermined time period to above a predetermined temperature. The fusible element and the heating element are arranged on the substrate in such a way, that heat created by the heating element is transported to the fusible element and the current flow through the heating element exceeds a threshold value for a predetermined time period. During production, the heating element is positioned next to the fusible element, at a predetermined distance from it. A predetermined, local thermal capacitance is set, at least approximately, at the location of the heating element and is coupled to the latter. Alternatively, a predetermined, local thermal capacitance is set at least at one predetermined location between the heating element and the fusible element. The capacitance accumulates part of the heat that is dissipated from the heating element to the fusible element. This produces, at least approximately, a defined time response of the thermal transmission from the heating element to the fusible element.
