Abstract
Die Erfindung betrifft eine Ladevorrichtung zum Laden eines elektrischen Energiespeichers (22) eines Kraftwagens (20), mit einem gebäudeseitigen elektrischen Energiespeicher (10), mittels dessen elektrischer Leistung der elektrische Energiespeicher (22) des Kraftwagens (20) aufladbar ist. Um einen Ladevorgang des elektrischen Energiespeichers (22) des Kraftwagens (20) zu verkürzen ist vorgesehen, dass die Ladevorrichtung eine gebäudeseitige Einrichtung (34) umfasst, mittels derer die durch den gebäudeseitigen elektrischen Energiespeicher (10) bereitgestellte elektrische Leistung mit einer durch einen gebäudeseitigen Netzanschluss (12) bereitgestellten elektrischen Leistung zur Erhöhung einer Ladeleistung des elektrischen Energiespeichers (22) des Kraftwagens (20) koppelbar ist.The invention relates to a charging device for charging an electrical energy store (22) of a motor vehicle (20), with a building-side electrical energy store (10), by means of which electric power of the electrical energy store (22) of the motor vehicle (20) is chargeable. In order to shorten a charging process of the electrical energy store (22) of the motor vehicle (20), it is provided that the charging device comprises a building-side device (34), by means of which provided by the building-side electrical energy store (10) electrical power with a through a building-side power supply (12) provided electrical power for increasing a charging power of the electrical energy storage device (22) of the motor vehicle (20) can be coupled.
Description
Die Erfindung betrifft eine Ladevorrichtung zum Laden eines elektrischen Energiespeichers eines Kraftwagens gemäß dem Oberbegriff des Patentanspruchs 1. Die Erfindung betrifft außerdem ein Verfahren zum Laden eines elektrischen Energiespeichers eines Kraftwagens gemäß dem Oberbegriff des Patentanspruchs 6.The invention relates to a charging device for charging an electrical energy store of a motor vehicle according to the preamble of patent claim 1. The invention also relates to a method for charging an electrical energy store of a motor vehicle according to the preamble of patent claim 6.
Ein Kraftwagen mit einem elektrischen Antrieb, insbesondere ein Elektrofahrzeug oder Hybridfahrzeug, umfasst einen elektrischen Energiespeicher, insbesondere einen Akkumulator oder eine Hochvoltbatterie zum Versorgen des elektrischen Antriebs mit elektrischer Energie. Dabei stellt der elektrischen Energiespeicher insbesondere eine Spannung von mehr als 80 Volt, vorzugsweise mehr als 200 Volt, bereit.A motor vehicle with an electric drive, in particular an electric vehicle or hybrid vehicle, comprises an electrical energy store, in particular a rechargeable battery or a high-voltage battery for supplying the electric drive with electrical energy. In particular, the electrical energy store provides a voltage of more than 80 volts, preferably more than 200 volts.
Der elektrische Energiespeicher kann mittels einer Ladevorrichtung zum Laden eines elektrischen Energiespeichers aufgeladen werden, wobei für eine kurze Ladedauer eine hohe Ladeleistung von Nöten ist. Zur Erzielung einer kurzen Ladedauer sind insbesondere Schnellladestationen als Ladevorrichtungen bekannt, welche zur Bereitstellung einer hohen Ladeleistung ausgebildet sind. Da der gebäudeseitige Netzanschluss eines Gebäudes, insbesondere eines Wohngebäudes, häufig nur geringe Ladeleistungen zulässt, ist die Ladedauer für den elektrischen Energiespeicher des Kraftwagens oft erhöht. Insbesondere am Wohnhaus eines Nutzers mit einem gebäudeseitigen Netzanschluss, welcher nur eine geringe Ladeleistung ermöglicht, kann die Ladedauer des elektrischen Energiespeichers des Kraftwagens unpraktikabel lang sein.The electrical energy storage device can be charged by means of a charging device for charging an electrical energy storage device, wherein for a short charging time a high charging power is needed. To achieve a short charging time, in particular fast charging stations are known as charging devices, which are designed to provide a high charging power. Since the building-side grid connection of a building, in particular a residential building, often allows only low charging power, the charging time for the electrical energy storage of the motor vehicle is often increased. In particular, at the home of a user with a building-side power supply, which allows only a small charging power, the charging time of the electric energy storage of the motor vehicle can be impracticably long.

Es ist Aufgabe der vorliegenden Erfindung einen Ladevorgang eines elektrischen Energiespeichers eines Kraftwagens gegenüber dem Stand der Technik zu beschleunigen.It is an object of the present invention to accelerate a charging process of an electrical energy storage device of a motor vehicle compared to the prior art.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Ladevorrichtung mit den Merkmalen des Patentanspruchs 1. Die Aufgabe wird außerdem gelöst durch ein Verfahren mit den Merkmalen des Patentanspruchs 6. Vorteilhafte Ausgestaltungen und nicht triviale Weiterbildungen sind Gegenstand der abhängigen Ansprüche.This object is achieved by a charging device having the features of claim 1. The object is also achieved by a method having the features of claim 6. Advantageous embodiments and not trivial developments are the subject of the dependent claims.
Um nun eine Ladevorrichtung zu schaffen, mittels derer einen Ladevorgang eines elektrischen Energiespeichers eines Kraftwagens gegenüber dem Stand der Technik zu beschleunigt werden kann, ist erfindungsgemäß vorgesehen, dass die Ladevorrichtung eine gebäudeseitige Einrichtung umfasst, mittels derer die durch den gebäudeseitigen elektrischen Energiespeicher bereitgestellte elektrische Leistung mit einer durch einen gebäudeseitigen Netzanschluss bereitgestellten elektrischen Leistung zur Erhöhung einer Ladeleistung des elektrischen Energiespeichers koppelbar ist. Auf diese Weise können in einem Betrieb der Ladevorrichtung die elektrischen Leistungen, welche durch den gebäudeseitigen elektrischen Energiespeicher sowie den gebäudeseitigen Netzanschluss bereitgestellt sind, zur Erhöhung der Ladeleistung des elektrischen Energiespeichers gekoppelt sein und insbesondere addiert sein. Der gebäudeseitige elektrische Energiespeicher ist insbesondere dann mittels des gebäudeseitigen Netzanschlusses aufladbar, wenn keine Ladeleistung zum Aufladen des elektrischen Energiespeichers des Kraftwagens benötigt ist. Durch die erfindungsgemäße Ladevorrichtung ist die Bereitstellung einer hohen Ladeleistung zum Laden des elektrischen Energiespeichers des Kraftwagens auch dann ermöglicht, wenn der gebäudeseitige Netzanschluss nur zur Bereitstellung einer geringen elektrischen Leistung ausgebildet ist.In order to provide a charging device by means of which a charging process of an electric energy storage device of a motor vehicle can be accelerated compared to the prior art, the invention provides that the charging device comprises a building-side device, by means of which provided by the building-side electrical energy storage electric power a provided by a building-side power supply electrical power for increasing a charging power of the electrical energy storage is coupled. In this way, in an operation of the charging device, the electrical powers which are provided by the building-side electrical energy store and the building-side grid connection to be coupled to increase the charging power of the electrical energy storage and in particular added. The building-side electrical energy storage is particularly rechargeable by means of the building-side power supply when no charging power is required to charge the electrical energy storage of the motor vehicle. By the charging device according to the invention, the provision of a high charging power for charging the electrical energy storage of the motor vehicle is also possible if the building-side power supply is designed only to provide a low electrical power.
