Abstract: A traction battery charging station for charging a traction battery of a motor vehicle having an electric traction motor. The charging station includes a converter that feeds DC voltage into a pair of two charging lines during charging operation, a charging controller, and an insulation monitor having two measuring resistors that are each connected to a charging line and are able to be connected to protective earth via a respective resistor switch. The insulation monitor monitors the electrical insulation of the pair of charging lines with respect to protective earth during non-charging and during charging of the traction battery. A test mode controller has a non-restricted non-charging test mode in which one resistor switch is closed and the other resistor switch is open at the same time, and a symmetric charging test mode in which both resistor switches are closed at the same time or open at the same time.

Abstract: A device for charging at least one battery has an electronics module and at least one charging pillar with a charging point. The electronics module has at least one power electronics unit having an AC/DC converter and a DC/DC converter, wherein the electronics module and the at least one charging pillar are spatially separate from one another.

Abstract: A transformer device for a charging station for electrically charging vehicles with at least two charging points, having an input connection for electrical connection to an electrical power source, also having a primary winding and at least one secondary winding for each charging point. The secondary windings are DC isolated from one another and each have at least one winding section which is connected electrically in parallel. Adjacent winding sections of at least one secondary winding overlap one another at least partially in an axial direction or radial direction.

Abstract: A method and corresponding system for providing a charging park having a plurality of charging points, in which all of the charging points are connected to a medium-voltage grid by a common transformer with overloading capability. A power electronics system is provided at each charging point, which power electronics system is designed to perform a quick-charging operation of a connected electrically driven vehicle that is to be charged, and a power drawn from the medium-voltage grid jointly by the charging points at a respective time is monitored centrally and/or decentrally and continuously at a grid contact point connected upstream of the transformer in the direction of the medium-voltage grid. An average power drawn from the medium-voltage grid jointly by the charging points is in each case adjusted over a prescribed time interval.
