Definitions
- the present invention relates to a charging station for charging electric vehicles comprising at least two charging points, which are each connected to an electric vehicle for charging a elec- tric energy storage of the electric vehicle.
- the charging station comprises at least two rectifier branches for respectively providing electrical energy, wherein the rectifier branches are electrically connected to the charging points and the electrical connection between at least one of the rectifier branches and the La deyaken is reversible.
- the charging station comprises at least one energy meter for providing counter values which describe the electrical energy provided by the rectifier branches.
- the present invention relates to a method of operating a charging station for charging electric vehicles.
- the interest here is directed to charging stations for charging electric vehicles and in particular to so-called fast charging stations.
- fast charging stations for electric vehicles it is customary to design them such that there is a central station and several optionally te des th charging points. With these charging points, the Elekt can be connected electric vehicles to load an electric energy storage of the electric vehicle.
- the individual compo nents in the central station are not necessarily assigned to a specific charging point, but are dynamically assigned to the charging points if possible.
- the utilization of high-priced components can be increased and the required number of identical components reduced (utilization of the simultaneity factor).
- the dynamics caused on the vehicle side is particularly strong over time.
- maximum charging currents due to the properties of the built-in electric vehicles energy storage or accumulators can be achieved only for relatively short times. Furthermore, it can be observed that there is a relatively wide variance of electric vehicles and their charging profile, which can not be readily subdivided into defined classes. Finally, the maximum charging current depends among other things on parameters such as the battery temperature, which can not be assumed to be constant.
- the charging stations or fast charging stations comprise appropriate rectifier branches, with which an AC side AC voltage or an AC current can be converted into an output DC voltage or a DC current.
- An output-side DC measurement of the electrical energy output zwangswei se leads to the fact that the meters must be designed for the entire dynamic range catch. Not only is the current highly dynamic, but also the output voltage is variable. This is due to power losses and due to different battery voltages. The consideration of the error propagation of two mutually multiplier ter sizes has a particularly unfortunate. In addition, further difficulties in the measurement, for example by Rippelströme.
- An alternative to the output-side measurement is the one-sided AC measurement.

Since the counter values recorded by the energy meters are billing-relevant, it must be ensured that an assignment to a customer or electric vehicle is possible. However, this requirement he has for several reasons as technically Schwiering rig.
- measuring instruments for the procurement of electrical energy are usually used to determine (multi) annual consumption of whole households, whereby random errors of successive measuring periods compensate each other in time (usually the same customer).
- the fast charging infrastructure is currently being set up in higher capacity classes. Previous approaches to energy only meet reduced requirements with regard to tamper-proofing and traceability of the measurement. However, it is to be expected that higher requirements will be required as part of the conformity assessments of the fast-charging infrastructure and that statutory transitional periods will not be extended.
