Die Energie aus dem Energiespeicher kann zum Starten der Verbrennungsmaschine, für die elektrischen Verbraucher im Fahrzeug und für Beschleunigungsvorgänge benutzt werden. Der Energiespeicher wird während der Fahrt über den Generator von der Verbrennungsmaschine gespeist. Zusätzlich ist es bekannt, den Energiespeicher durch Energierückgewinnung beim Bremsen aufzuladen.The Energy from the energy store can be used to start the combustion engine, for the electrical Consumers in the vehicle and for acceleration processes to be used. The energy storage is while driving over the Generator powered by the combustion engine. In addition is it is known to charge the energy storage by energy recovery during braking.
Über eine Steuerelektronik (auch "Hybrid-Controller" genannt) werden die verschiedenen Modi gesteuert, unter anderem, ob dem Energiespeicher Energie entnommen oder zugeführt werden soll.Over a Control electronics (also called "hybrid controllers") the different modes controlled, among other things, whether the energy storage Energy taken or supplied shall be.
In den verschiedenen Ausführungen eines Hybridantriebes, z. B. parallel, seriell oder Kombinationen aus beiden, wird der Energiespeicher üblicherweise durch den über die Verbrennungsmaschine motorisch angetriebenen Generator geladen.In the different versions a hybrid drive, z. As parallel, serial or combinations from both, the energy storage is usually through the over Internal combustion engine loaded by a motor driven generator.
Für ausschließlich elektrisch angetriebene Fahrzeuge oder für die herkömmliche Bordnetzbatterie ist es bekannt, diese bzw. den Energiespeicher des elektrisch angetriebenen Fahrzeuges über ein externes Energieversorgungs-Terminal zu laden.For electric only powered vehicles or for the conventional one On-board battery, it is known this or the energy storage of electrically powered vehicle via an external power supply terminal to load.
Der Erfindung liegt die Aufgabe zugrunde, ein gegenüber dem Stand der Technik verbessertes Verfahren und eine Vorrichtung zum Laden eines Energiespeichers eines Hybridantriebes anzugeben.Of the Invention is based on the object, a comparison with the prior art improved method and a device for charging an energy storage of a hybrid drive specify.
Die Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des Anspruchs 1. Hinsichtlich der Vorrichtung wird die Aufgabe erfindungsgemäß gelöst durch die Merkmale des Anspruchs 7.The The object is achieved by the features of claim 1. With respect to the device is the object is achieved by the features of claim 7.
Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.advantageous Further developments of the invention are the subject of the dependent claims.
Beim erfindungsgemäßen Verfahren zum Laden eines Energiespeichers, welcher zur Bereitstellung von für die Ladung erforderlicher Energie mit einem von einer Verbrennungsmaschine und/oder einer elektrischen Maschine eines Hybridantriebes direkt bzw. indirekt angetriebenen Generator gekoppelt wird, werden bei Stillstand des Hybridantriebs zum Nachladen des Energiespeichers mindestens eine fahrzeugexterne Ladeeinrichtung (auch externer Erzeuger elektrischer Energie genannt) und bei Betrieb oder Stillstand des Hybridantriebs mindestens eine von weiteren fahrzeugeigenen Ladeeinrichtungen eingesetzt. Anstelle des Generators kann auch eine Lichtmaschine zum Laden des Energiespeichers während des Betriebes des Hybridantriebes eingesetzt werden.At the inventive method for charging an energy store, which is for providing for the Charge required energy with one of an internal combustion engine and / or an electric machine of a hybrid drive directly or indirectly driven generator is coupled with Standstill of the hybrid drive for recharging the energy storage at least one vehicle-external charging device (also external producer called electrical energy) and during operation or shutdown of the Hybrid drive used at least one of other on-board charging devices. Instead of the generator can also be an alternator for charging the Energy storage during the operation of the hybrid drive can be used.
Der Energiespeicher umfasst bevorzugt mehrere seriell und/oder parallel geschaltete Zellen. Die Zellen sind wiederaufladbar. Der Energiespeicher ist beispielsweise eine Starter-, Traktions- oder Bordnetzbatterie, welche die elektrische Maschine und/oder andere Verbraucher mit ausreichend Energie speisen. Bei dem Energiespeicher kann es sich beispielsweise um herkömmliche Blei-Säure-Batterien, Nickel-Cadmium-Batterien, Nickel-Metallhybrid-Batterien, Lithium-Ionen-Batterien und/oder so genannte Superkondensatoren (auch Ultracaps oder Supercaps genannt) handeln.Of the Energy storage preferably comprises a plurality of serial and / or parallel switched cells. The cells are rechargeable. The energy storage is for example a starter, traction or electrical system battery, which the electric machine and / or other consumers with to eat enough energy. The energy store may be, for example to conventional Lead-acid batteries, Nickel-cadmium batteries, Nickel-metal hybrid batteries, lithium-ion batteries and / or so-called Supercapacitors (also called ultracaps or supercaps) act.
In einer möglichen Ausführungsform wird bei Stillstand des Hybridantriebs der Energiespeicher mit einer externen Stromquelle eines zentralen Stromversorgungsnetzes, die als fahrzeugexterne Ladeeinrichtung dient, verbunden. Dabei wird der Energiespeicher beispielsweise im Stand oder beim Parken eines mit einem Hybridantrieb ausgestatteten Fahrzeugs kontinuierlich geladen. Als externe Stromquelle kann jede mögliche Stromquelle vorgesehen sein, die nicht die Verbrennungsmaschine und/oder die elektrische Maschine des Hybridantriebes ist. Beispielsweise kann als externe Stromquelle auch ein stromnetzunabhängiges System, z. B. eine Solaranlage, ein Brennstoffzellensystem, eine Windenergieeinrichtung, eingesetzt werden. Durch das Laden des Energiespeichers mittels einer externen Stromquelle im Stillstand des Fahrzeuges, d.h. während das Fahrzeug steht oder parkt, kann der Energiespeicher beispielsweise vor dem erneuten Fahrbetrieb auf einen besonders hierfür und den Energiespeicher günstigen Ladezustand (kurz SoC genannt) gebracht werden. In der Regel liegt der Ladezustand des Energiespeichers bei 50% bis 60% unter normalen Betriebsbedingungen, bei tiefen Temperaturen auch bei 70%. Durch Laden des Energiespeichers über eine externe Stromquelle, wenn dieser einen unterhalb des zulässigen Ladezustands sehr niedrigen Ladezustand aufweist und/oder wenn das Fahrzeug für lange Zeit abgestellt ist oder wird, wird der Energiespeicher geschont und dessen Lebenserwartung deutlich verlängert.In one possible embodiment, when the hybrid drive is at standstill, the energy store is connected to an external power source of a central power supply network, which serves as a vehicle-external charging device. In this case, the energy storage is continuously charged, for example, in the state or when parking a vehicle equipped with a hybrid drive. As an external power source may be provided any possible power source, which is not the internal combustion engine and / or the electric machine of the hybrid drive. For example, as an external power source, a power supply independent system, for. As a solar system, a fuel cell system, a wind energy device, are used. By charging the energy storage device by means of an external power source at standstill of the vehicle, ie while the vehicle is parked or parked, the energy storage, for example, before re-driving on a particularly favorable for this and the energy storage state of charge (short SoC called) are brought. As a rule, the state of charge of En energy storage at 50% to 60% under normal operating conditions, at low temperatures even at 70%. Charging the energy store via an external power source when it has a very low state of charge below the permissible state of charge and / or when the vehicle is switched off for a long time saves energy storage and significantly extends its life expectancy.
In einer weiteren vorteilhaften Ausführungsform wird bei Betrieb des Hybridantriebs und/oder bei Stillstand des Hybridantriebs der Energiespeicher mit dem Generator verbunden, der zusätzlich oder alternativ zur Verbrennungsmaschine von einer Hilfsverbrennungsmaschine, die als fahrzeugeigene Ladeeinrichtung dient, angetrieben wird. Als Hilfsverbrennungsmaschine eines mit einem Hybridantrieb ausgestatteten Fahrzeuges kann beispielsweise eine Verbrennungsmaschine einer treibstoffbetriebenen Standheizung oder jede andere geeignete treibstoffbetriebene Maschine verwendet werden.In A further advantageous embodiment is in operation the hybrid drive and / or at standstill of the hybrid drive the Energy storage connected to the generator, in addition to or alternatively to the combustion engine of an auxiliary combustion engine, which serves as an on-board charger, is driven. As an auxiliary combustion engine equipped with a hybrid drive Vehicle can, for example, an internal combustion engine of a fuel-powered auxiliary heater or any other suitable fuel-powered machine become.
Alternativ oder zusätzlich kann bei Vorhandensein von fahrzeugeigenen anderen Stromquellen, wie z. B. einem auf einem Fahrzeugdach integrierten Solarsystem und/oder einem im Fahrzeug integrierten Brennstoffzellensystem, der Energiespeicher über diese weiteren fahrzeugeigenen Stromquellen geladen werden. Dabei wird der Energiespeicher insbesondere über diese fahrzeugeigenen Stromquellen je nach Anforderung diskontinuierlich oder kontinuierlich geladen.alternative or additionally can in the presence of other vehicle power sources, such as z. B. a solar system integrated on a vehicle roof and / or a fuel cell system integrated in the vehicle, the energy storage via this be loaded further vehicle power sources. It will the energy storage in particular on this vehicle's own power sources charged discontinuously or continuously as required.
Darüber hinaus kann bei Betrieb des Hybridantriebs der Energiespeicher mit einer Rekuperationseinrichtung verbunden werden, welche die Wärme des Abgases der Verbrennungsmaschine in elektrische Energie umwandelt und als fahrzeugeigene Ladeeinrichtung dient. Mit anderen Worten: Die Rekuperationseinrichtung dient als eine weitere Stromquelle, welche aus der Wärme des Abgases der Verbrennungsmaschine elektrische Energie er zeugt. Ein derartiges insbesondere diskontinuierliches oder kontinuierliches Laden des Energiespeichers während der Fahrt ermöglicht einen besonders guten Wirkungsgrad des Gesamtsystems aus Hybridantrieb und Energiespeicher. Vorteilhafterweise wird als Rekuperationseinrichtung ein Turbolader, ein Peltier-Element, eine Dampfmaschine oder ein Stirling-Motor eingesetzt, welche im Betrieb mit dem Generator oder der Lichtmaschine verbunden werden bzw. sind.Furthermore can in operation of the hybrid drive of the energy storage with a Rekuperationseinrichtung be connected, which the heat of Exhaust gas of the internal combustion engine converts into electrical energy and serves as an in-vehicle charger. In other words: The recuperation device serves as another power source, which from the heat the exhaust gas of the internal combustion engine electrical energy he testifies. Such a particular discontinuous or continuous Charging the energy storage during the ride allows a particularly good efficiency of the overall system of hybrid drive and energy storage. Advantageously, as Rekuperationseinrichtung a turbocharger, a Peltier element, a steam engine or a Stirling engine used in operation with the generator or the alternator are connected or are.

Darüber hinaus können Alterungseffekte bei einem zu kalten und gegebenenfalls zu stark belasteten Energiespeicher minimiert werden.In a further embodiment is provided that the energy storage by the waste heat of Internal combustion engine is heated. By using the waste heat of Combustion engine for optimized temperature control of the energy storage can maximizes the performance of the energy store at the same size become. About that can out Aging effects if too cold and possibly too strong charged energy storage can be minimized.

Dabei können bzw. kann fahrzeugseitig ein Steckeranschluss und/oder eine Buchse vorgesehen sein. Auch kann eine Steuereinheit vorgesehen sein, über welche der Ladevorgang des Energiespeichers, z. B. hinsichtlich Ladestrom, Ladezeit, Ladespannung, etc. gesteuert und geregelt wird.
