Charging station

A DC voltage source, for example an AC/DC converter, has an output producing a controllable DC voltage for a DC charging station to charge the battery of an electric vehicle. A voltage balancing unit is connected between the output of the converter and the output terminal of the DC charging station. The voltage balancing unit has a controllable switch by which the connection between voltage source or converter and battery can be made or broken as desired. The switch is controlled as a function of the voltage on the input and output side of the voltage balancing unit to the effect that the switch breaks the connection before and while the battery is being connected to the DC output terminal, and makes a connection only when the voltage on the input side of the voltage balancing unit corresponds substantially to the voltage on the output side of the voltage balancing unit.

A method is disclosed for charging at least one energy store of an electric vehicle via a charging point, using a first terminal having first connecting elements of a charging cable connected to the charging point. The first connecting elements are connected to corresponding second connecting elements of a second terminal on the vehicle, and the first and second connecting elements are designed to supply alternating current for charging the at least one energy store. Direct current from the charging point for charging the at least one energy store is supplied to the electric vehicle via at least two first connecting elements or at least two third connecting elements of the first terminal, wherein PLC communication between the electric vehicle and charging point in order to exchange information relating to the charging operation occurs via one or more first connecting elements on which no direct current for charging is carried.

An RFID transponder comprises an electronic assembly and an antenna assembly. The electronic assembly is a multi-layer film body having one or more electrically conducting functional layers and one or more electrically semiconducting functional layers. The antenna assembly has one or more electrically conducting functional layers, of which one is an antenna coil. In a first region and a second region of the body a respective one of the one or more electrically conducting functional layers forms respective first and second capacitor plates. In addition, in the first region and the second region of the body a respective one of the one or more electrically conducting functional layers of the antenna assembly is formed as a third and a fourth capacitor plate so that the electronic assembly and the antenna assembly are electrically coupled by capacitors formed respectively by the first and third and by the second and fourth capacitor plates.

A communication system is proposed which, as its communication elements (KE) has a gatekeeper (GK), a gateway (GW) coupled to the gatekeeper (GK) and at least one communication unit (KEH) coupled to the gateway (GW), with the communication system being set up so that, to register a communication relationship of the communication unit (KEH) in the communication system (KS), a request message (ANF) is transmitted from the communication unit (KEH) via the gateway (GW) to the gatekeeper (GK), which is checked in the gateway (GW) for authenticity and in the gatekeeper (GK) for authorization.
