Für das Laden von Baterien aus Elektrofahrzeugen stellen Ladestationen entweder Gleichstrom oder Wechselstrom bereit. Beim Wechselstromladen wird normalerweise ein im Elektrofahrzeug mitgeführtes Ladegerät, ein sogenannter On-Board-Charger, verwendet. Der On-Board-Charger erzeugt eine Gleichspannung bzw. einen Gleichstrom zum Laden der Baterie. Seine Eingangsspannung bezieht er aus einer sogenannten Wallbox, die bspw. von einem Energieversorger an einer Ladestation zu Verfügung gestellt wird. Allerdings ist ein Eingangsspannungsbereich des On-Board-Chargers begrenzt und muss vorsorglich bzgl. verschiedenphasiger Wechselspannungssysteme, bspw. einphasig oder dreiphasig, ausgelegt sein. Weiter nachteilig ist auch, dass beim Wechselstromladen mehrere Wandlerstufen eingesetzt werden, mit jeder Wandlerstufe aber ein elektrischer Verlust einhergeht. Beide Ladestandards benötigen separate Installationen von Ladegeräten, die jeweils auf Anforderungen der Elektrofahrzeuge bzw. Spezifikationen der Energieversorger zugeschniten sein müssen. Hohe For charging electric vehicle batteries, charging stations provide either DC or AC power. AC charging usually involves the use of a charger, a so-called on-board charger, carried in an electric vehicle. The on-board charger generates a DC voltage or a DC current for charging the battery. He draws his input voltage from a so-called wallbox, which is provided, for example, by an energy supplier to a charging station. However, an input voltage range of the on-board charger is limited and must be designed as a precaution with respect to different-phase AC voltage systems, for example single-phase or three-phase. Another disadvantage is that when AC charging multiple converter stages are used, with each converter stage but an electrical loss is accompanied. Both charging standards require separate installations of chargers, each of which must be tailored to the requirements of electric vehicles or energy suppliers' specifications. Height
Installationskosten sind die Folge. Installation costs are the result.
Beim Gleichstromladen, welches auch als Schnellladen bezeichnet wird, wird die When DC charging, which is also referred to as fast charging, the
Gleichspannung bzw. der Gleichstrom direkt von der Ladestation zur Verfügung gestellt und kein On-Board-Charger benötigt. Obwohl letzterer ein zusätzliches Gewicht darstellt, wird er in dem Elektrofahrzeug aber mitgeführt, da prinzipiell auch das DC voltage or direct current provided directly from the charging station and no on-board charger needed. Although the latter is an additional weight, it is carried in the electric vehicle but because in principle also the
Wechselstromladen möglich sein soll. Auch beim Gleichstromladen kommt eine Mehrzahl von Wandlerstufen zum Einsatz.  AC charging should be possible. Even when DC charging a plurality of converter stages is used.
Vorteilhaft verwendet die Druckschrift US 2007/0274109 Al in einem Elektrofahrzeug einen Matrixkonverter zum direkten Übertragen von Wechselstrom zwischen zwei Elektromotoren. Da keine Umwandlung von Wechselstrom zu Gleichstrom und wieder in Wechselstrom benötigt wird, können so Energieverluste vermieden werden. Advantageously, document US 2007/0274109 Al in an electric vehicle uses a matrix converter for directly transmitting alternating current between two Electric motors. Since no conversion from AC to DC and back into AC is needed, so energy losses can be avoided.
Neuerdings werden Anforderungen betreffend eines bidirektionalen Energieflusses erhoben, um an eine Ladestation angeschlossene Batterien auch zu einer Recently, requirements regarding a bi-directional flow of energy are raised to also connected to a charging station batteries
Netzstabilisierung in einem Niederspannungsnetz heranzuziehen, oder auch zu weiteren Netzdienstleistungen zu verwenden. Hierbei müssen alle Wandlerstufen mit entsprechend geeigneten Leistungshalbleiterschaltern ausgestattet werden. Allgemein beschreibt die US-amerikanische Druckschrift US 2013/0103191 Al ein System und ein Verfahren zu Daten- und Energieaustausch zwischen einem Ladegerät und einer Batterie und insbesondere der hierzu benötigten Schnittstellen. Weiter offenbart die Druckschrift US 2013/0069424 Al ein im Elektrofahrzeug mitgeführtes und mit der Batterie verbundenes elektrisches System, welches einen extern von einem Stromnetz zur Verfügung gestellten Wechselstrom zum Gleichstromladen der Batterie in Gleichstrom umwandelt. Umgekehrt kann das elektrische System aber auch zu einer Grid stabilization in a low-voltage network to use, or to use other network services. All converter stages must be equipped with suitable power semiconductor switches. Generally, US-A-2-D-US 2013/0103191 A1 describes a system and method for data and energy exchange between a charger and a battery, and in particular the interfaces required therefor. Further, document US 2013/0069424 A1 discloses an electric vehicle carried and connected to the battery electrical system which converts an external power source AC provided for DC charging of the battery to DC power. Conversely, the electrical system but also to a
Stromkonditionierung eines externen Stromnetzes herangezogen werden, indem es den von der Batterie zur Verfügung gestellten Gleichstrom zu Wechselstrom umwandelt und dem externen Stromnetz zuführt. Power conditioning of an external power grid can be used by converting the provided by the battery DC power to AC power and the external power supply.

Verschiedene Netzspannungen sollen genauso wenig ein Hindernis darstellen wie Kompatibilitätsprobleme mit Anschlüssen vorhandener oder zukünftiger Ladestationen. Des Weiteren soll ein bidirektionaler Energiefluss möglich sein. Ferner ist es eine Aufgabe der vorliegenden Erfindung, ein entsprechendes mit dem Ladegerät ausführbares Verfahren bereitzustellen. Zur Lösung der voranstehend genannten Aufgabe wird ein Ladegerät zum Energieaustausch zwischen einem Versorgungsnetz an einer Ladestation und einer Batterie eines Elektrofahrzeugs bereitgestellt, wobei das Ladegerät einen Includes AC charging as well as DC charging, allows and saves both manufacturing costs and weight over the previously used concepts.

Furthermore, a bidirectional flow of energy should be possible. Further, it is an object of the present invention to provide a corresponding charger implementable method. To solve the above object, a charger for energy exchange between a supply network to a charging station and a battery of an electric vehicle is provided, wherein the charger a

Üblicherweise handelt es sich bei dem im Versorgungsnetz fließenden Wechselstrom entweder um einen einphasigen Wechselstrom, oder, im Falle eines Drehstromnetzes, um einen dreiphasigen Wechselstrom. Der Hochfrequenztransformator wird dabei im  Usually, the alternating current flowing in the supply network is either a single-phase alternating current or, in the case of a three-phase network, a three-phase alternating current.

Generally three-phase (N = 3) designed so that each results in a three by three matrix of bidirectional power semiconductor switches in each matrix converter.
