  • Charging station having differential current monitoring for charging an electric energy storage means of an electric vehicle
    Patent number: 10759297
    Abstract: A charging station for charging an electric energy storage means of an electric vehicle using alternating charging current, having a fault-current protective device and having a charging controller. The fault-current protective device is divided into its functional units, a differential-current monitoring unit forming an integral structural unit in the form of a charging-current controller and monitoring device in conjunction with the charging controller according to the invention. Alternatively, the fault-current protective device forms an integral structural unit in the form of a charging-current controller and protective device in conjunction with charging controller.

  • CHARGING STATION HAVING DIFFERENTIAL CURRENT MONITORING FOR CHARGING AN ELECTRIC ENERGY STORAGE MEANS OF AN ELECTRIC VEHICLE
    Publication number: 20190023143
    Abstract: The invention relates to a charging station for charging an electric energy storage means of an electric vehicle using alternating charging current, having a fault-current protective device and having a charging controller. In a first embodiment, the fundamental idea is based on carrying out the fault-current protective device modularly. For this purpose, the modular fault-current protective device is divided into its functional units, a differential-current monitoring unit forming an integral structural unit in the form of a charging-current controller and monitoring device in conjunction with the charging controller according to the invention. In an alternative embodiment, the fault-current protective device forms an integral structural unit in the form of a charging-current controller and protective device in conjunction with charging controller.
