The disclosure relates to a modular measuring unit comprising a measuring module and an access module. The measuring module and the access module are connected via an interface internal to the measuring unit. The defined interface guarantees modular isolation of the measuring module for the determination of a measured data item from the access module for generating a measuring data set with assignment of an identification data item. Because of this modular isolation, technical changes or developments in the access module do not necessarily lead to a loss of an approval under calibration legislation of the measuring module, as its core function significant under calibration legislation remains untouched. The modular measuring unit interacts with an authentication apparatus, which may be provided as a remote instance apart from a charging station.

Modular measuring unit and authentication apparatus for detecting energy output

The invention relates to a method for the computer-aided parameterisation of a technical system () in which the technical system () is used to store a software package (SP) that is signed with a first digital signature (SIG) and comprises a test program (PM). The technical system () checks the validity of the first digital signature (SIG). If the first digital signature (SIG) is valid, the software package (SP) is installed on the technical system (), wherein during the installation the test program (PM) checks whether a number of rules (RU), at least some of which are stored in the test program (PM), are observed by external digital information (DA) coming from outside the software package (SP). If there is a number of conditions (CO) comprising observance of the number of rules (RU) by the external digital information (DA), parameter setting is performed in the technical system () by means of the external digital information (DA) and otherwise the method is terminated.

The invention relates to a method for setting at least one communication parameter of a communication module () of a charging station (), used for communication, in particular wired communication, via an interface () of the charging station (). The invention addresses the problem of enabling the at least one communication parameter to be set in the simplest manner possible, with significant reliability and great security. It is proposed according to the invention that: &#x2014;a calibration device () is coupled to the interface (), &#x2014;authentication data is transmitted from the calibration device () to the communication module (), &#x2014;a value for the at least one communication parameter is transmitted from the calibration device () to the communication module (), and&#x2014;the at least one communication parameter is set by the communication module () depending on an evaluation of the authentication data by the communication module () according to the value transmitted.

Setting a communication parameter of a communication module of a charging station

The invention relates to means for a calibration standards-compliant determination of the electrical energy transferred from a charging station, which make a measurement at the transfer point, that is to say at the vehicle-side end of the charging cable, unnecessary. Here, the electrical energy transferred from a charging station is determined by a measurement of the energy before the transfer point, wherein the reactive power component from the termination point as far as the transfer point is compensated. The reactive power component is determined from at least one second electrical variable, for example a resistance of a conductor or a conductor shield, which is in a fixed relationship with an analog electrical variable that is relevant to the transferred electrical energy, for example an ohmic total resistance of at least two conductors involved in a charging circuit.

The disclosure relates to a charging system for charging an electrical energy storage device in an electric vehicle. The charging system includes: an input for an alternating current, which is provided with a source of electrical energy, at least one transformer element for transforming the alternating current into a direct current, and a charge output for connecting the charging system to the electric vehicle. The charging system is configured to connect the at least one transformer element to the charge output for charging the electrical energy storage device with direct current. The charging system is further configured to connect the input to the charge output for charging the electrical energy storage device with alternating current.

The invention relates to a method for providing data packets () from a CAN bus (), in particular a charging station for a motor vehicle. In order to permit a resource-saving and nevertheless secure possible way of providing data packets (), steps are provided: detection of the data packets () from at least one component () of the CAN bus () by a detection unit () which is part of the CAN bus (), creation of at least one web resource () which contains the data packets () in accordance with a predetermined specification by a computing unit (), wherein only data packets () which are related in accordance with the predetermined specification are combined in the at least one web resource (), transmission of a content of the at least one web resource () from the computing unit () to a receiving device () by means of a communication unit () via a data link () having a transmission protocol that differs from the CAN bus ().

Method for providing data packets from a CAN bus, control device and system having a CAN bus

The method for a two-stage authorization of a charging operation includes a first stage and a second stage. In the first stage, a control device allocated to the charging station receives a terminal-side proof of authorization transmitted from a mobile terminal device. The first personal authorization of the charging station user is verified on the basis of the terminal-side proof of authorization, without any action of the charging station user being required. With the given first authorization, the charging cable is released. In the second stage, the vehicle-side proof of authorization is received and verified after the vehicle has been connected to the charging cable, whereupon in response to verification of the vehicle-side proof of authorization, a second authorization is carried out, due to which the charging operation is approved.
