Abstract: The invention relates to a method for the computer-aided parameterisation of a technical system (1) in which the technical system (1) is used to store a software package (SP) that is signed with a first digital signature (SIG1) and comprises a test program (PM). The technical system (1) checks the validity of the first digital signature (SIG1). If the first digital signature (SIG1) is valid, the software package (SP) is installed on the technical system (1), 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 (1) by means of the external digital information (DA) and otherwise the method is terminated.

Abstract: The invention relates to a method for setting at least one communication parameter of a communication module (28) of a charging station (10), used for communication, in particular wired communication, via an interface (18) of the charging station (10). 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: —a calibration device (56) is coupled to the interface (18), —authentication data is transmitted from the calibration device (56) to the communication module (28), —a value for the at least one communication parameter is transmitted from the calibration device (56) to the communication module (28), and—the at least one communication parameter is set by the communication module (28) depending on an evaluation of the authentication data by the communication module (28) according to the value transmitted.

Abstract: 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.

Abstract: The disclosure relates to a management unit for managing a plurality of measurement units involved in a charging process, wherein distinguishable process identifiers are generated from a piece of authentication data of a user. A process identifier is transferred to a measurement unit involved in a charging process and integrated in a measurement data set from then on. Such a charging process also includes different phases of a charging process, wherein current branches joining or exiting are involved in each phase. Providing distinguishable process identifiers based on authentication data advantageously provides a unique allocation between a charging process and a user and a unique allocation of a plurality of measurement data sets generated by different measurement units to a charging process of the user, even if these change, join or exit during the charging process due to a charging power controlled in variable switching steps of the current branch.

Abstract: 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.

Abstract: 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.

Abstract: To protect a charging station LS against improper use, a second identification feature ID2 is also checked in addition to a first identification feature ID 1. The charging process is only authorized or continued if the check of the second identification feature ID2 was also successful. The authentication or authorization is thus implemented in a low-threshold manner by means of an additional authentication, in which a weak identification is supplemented by one or more further automatic identifications, which can also be checked continuously. This means that an authorized and genuine user does not incur any additional expense, while at the same time any damage caused by behavior in breach of contract by authorized users can be greatly reduced. Related system and methods for protecting against unauthorized use are also disclosed.

Abstract: A method for a device-dependent provision of download resources provides a request of a device to a server with transfer of a proof of identity. An allocation of device properties is carried out in the server based on the proof of identity. This is followed by a collation of at least one download resource based on the device properties. This collation may occur after the receipt of the request, to tailor the selection of the downloadable resources to the individual device properties or the software installations thereof. This is followed by a configuration on the server side of at least one resource address on which the selection of download resources is provided for download. A response message is sent to the device in response to the request, where the response message contains the at least one resource address for accessing the at least one download resource.

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.
