BeschreibungDescription
Die Erfindung bezieht sich auf ein Kraftfahrzeug, welches als reines Elektrofahrzeug oder als Hybridfahrzeug mittels eines Elektro-Fahrantriebes antreibbar ist und dazu einen aufladbaren Energiespeicher aufweist.The invention relates to a motor vehicle which can be driven as a pure electric vehicle or as a hybrid vehicle by means of an electric drive and which has a rechargeable energy storage device.
Der Energiespeicher solcher an sich bekannter Fahrzeuge wird bei üblichen Fahrzyklen nicht vollständig entladen. Um die möglichst uneingeschränkte Mobilität zu gewährleisten, werden die Fahrzeuge jedoch nach Fahrtende unmittelbar an das öffentliche elektrische Netz angeschlossen, so daß der Energiespeicher möglichst bald wieder voll geladen ist. Der Ladevorgang selbst ist bereits im großen Maße optimiert worden {Beispiel DE 39 02 339 Al) und auch der Entladevorgang während der Fahrt kann variabel verschiedenen Kriterien angepaßt werden (DE 31 12 629 Al). Wie aus den genannten Druckschriften hervorgeht, existieren auch Batteriemanager {Steuergeräte), die den Lade- und Entladevorgang optimiert steuern und die Batterie- und Fahrzeugkenndaten verfügbar machen.The energy storage of such known vehicles is not completely discharged during normal driving cycles. In order to ensure the most unrestricted mobility possible, the vehicles are immediately connected to the public electrical network after the end of the journey so that the energy storage is fully charged again as soon as possible. The charging process itself has already been optimized to a large extent (example DE 39 02 339 Al) and the discharging process during the journey can also be variably adapted to different criteria (DE 31 12 629 Al). As can be seen from the documents mentioned, there are also battery managers (control units) that control the charging and discharging process in an optimized manner and make the battery and vehicle characteristics available.
Es ist Aufgabe der Erfindung, den Ladevorgang im Hinblick auf entstehende Energiekosten zu optimieren und einen aktiven Beitrag zum globalen Umweltschutz zu leisten.The object of the invention is to optimize the charging process with regard to the resulting energy costs and to make an active contribution to global environmental protection.
Zur Lösung dieser Aufgabe zeichnet sich das erfindungsgemäße Kraftfahrzeug durch alle im Schutzanspruch 1 angege-To achieve this object, the motor vehicle according to the invention is characterized by all the features specified in claim 1.
benen Merkmale aus. Einzelheiten der Erfindung ergeben sich aus den Schutzansprüchen 2 bis 6.The details of the invention emerge from claims 2 to 6.
Das Fahrzeug ist mit einer Bedieneinheit ausgestattet, an der konkrete Vorgaben über den als nächstes geplanten Fahrzyklus eingegeben werden können. Diese Daten werden in einer Steuereinheit verarbeitet, welche in Verbindung mit einem Ladegerät und/oder mit einem Batteriemanager (Batteriesteuergerät) steht und die den kommenden Ladevorgang selbsttätig optimiert. Der Ladevorgang wird also an den nächsten Fahrzyklus angepaßt. Parameter des nächsten Fahrzyklus können sein:The vehicle is equipped with a control unit where specific specifications for the next planned driving cycle can be entered. This data is processed in a control unit which is connected to a charger and/or a battery manager (battery control unit) and which automatically optimizes the upcoming charging process. The charging process is therefore adapted to the next driving cycle. Parameters of the next driving cycle can be:
Beginn der nächsten Fahrt,
geplante Fahrstrecke (Reichweite), Steigung innerhalb der Fahrstrecke, Fahrzeuglast oder andere.Start of the next trip,
planned route (range), gradient within the route, vehicle load or others.
Es ist auch möglich, gespeicherte Fahrzyklen (wie beispielsweise den Standard-Arbeitsweg) mittels Kurzcode als nächsten Fahrzyklus anzugeben.It is also possible to specify saved driving cycles (such as the standard commute) as the next driving cycle using a short code.
Insbesondere kann so erreicht werden, daß Ladevorgänge vornehmlich nachts bei günstigen Stromtarifen stattfinden. Nur wenn diese Nachtzeit nicht für den Ladevorgang ausreicht, der für den nächsten Fahrzyklus nötig ist, wird im Tagestarif-Zeitabschnitt geladen. Da die Fahrzeugführer bislang nicht ohne weiteres in der Lage sind, zu überschlagen, ob die Nachladezeit ausreicht, um das nächste Ziel sicher zu erreichen, übernimmt dies nunmehr die genannte Steuereinheit. So ist es möglich, den Ladevorgang kostenmäßig zu optimieren, da Nachtstrom billiger ist als Strom in der Hochverbrauchs-Tageszeit. Ein weiterer vorteilhafter Effekt ist, daß die Kraftwerksauslastung günstiger zu gestalten wäre, wenn viele Fahrzeug-Energiespeicher nachts geladen werden. Dies würde zur Verbilligung der Energieherstellungs- und -bereitstel-In particular, this means that charging processes primarily take place at night when electricity rates are low. Only if this night-time period is not sufficient for the charging process required for the next driving cycle, will charging take place during the daytime rate period. Since vehicle drivers have not yet been able to easily estimate whether the recharging time is sufficient to safely reach the next destination, this is now done by the control unit mentioned. This makes it possible to optimize the charging process in terms of costs, since night-time electricity is cheaper than electricity during the peak consumption period of the day. Another advantageous effect is that the power plant utilization would be more favorable if many vehicle energy storage units were charged at night. This would make energy production and provision cheaper.
lungskosten führen. Als dritter wesentlicher Vorteil ist zu nennen, daß die Grundstromversorgung, also die elektrische Energie, die tags- und nachtsüber gleichsam zur Verfügung zu stellen ist, von sogenannten Grundlastkraftwerken sehr umweltfreundlich produziert wird. Die Spitzenlastkraftwerke arbeiten weniger umweltfreundlich. So wird das Nacht-Laden der Fahrzeug-Energiespeicher einen Umweltschonprozeß zur Folge haben, da der Energieverbrauch sich in Richtung Grundlast verschiebt und ein geringerer Spitzenenergiebedarf besteht.The third major advantage is that the basic power supply, i.e. the electrical energy that is available both day and night, is produced in a very environmentally friendly way by so-called base load power plants. The peak load power plants are less environmentally friendly. For example, charging the vehicle energy storage units at night will result in an environmentally friendly process, as energy consumption will shift towards the base load and there will be a lower peak energy requirement.
Zur Ausführung der Erfindung wird im Kraftfahrzeug mit Elektro-Fahrantrieb und Energiespeicher eine Bedieneinheit angeordnet. Diese kann auch schon vorab für andere Zwecke vorhanden sein. Gleiches gilt für eine Ausgabeeinheit, die zur Fahrer-Fahrzeug-Kommunikation sinnvoll anzuordnen ist. Die Bedieneinheit ist mittels einer Signalverbindung mit einer Steuereinheit zu verbinden. Auch die Steuereinheit kann neu vorgesehen werden oder der Funktionsumfang einer vorhandenen Steuereinheit wird erweitert. Die Steuereinheit ist mit der Ausgabeeinheit zu verbinden und ihr können des weiteren auch Fahrzeugbetriebskennwerte zugeführt werden. Die Kommunikation der einzelnen Einheiten untereinander ist auch über ein Fahrzeug-BUS möglich. To implement the invention, a control unit is arranged in the motor vehicle with electric drive and energy storage. This can also be present in advance for other purposes. The same applies to an output unit, which is to be arranged sensibly for driver-vehicle communication. The control unit is to be connected to a control unit using a signal connection. The control unit can also be newly provided or the range of functions of an existing control unit can be expanded. The control unit is to be connected to the output unit and vehicle operating parameters can also be fed to it. The individual units can also communicate with each other via a vehicle BUS.
Über die Bedieneinheit werden der Steuereinheit die genannten Parameter des nächsten gewünschten Fahrzyklus mitgeteilt. Die Steuereinheit hat nun die Aufgabe den nächsten Ladezyklus zu optimieren. Wird das Fahrzeug mittels Ladegerät an ein elektrisches Netz angeschlossen, um den Energiespeicher zu laden, wird dies nicht wie üblich unbedingt sofort erfolgen, sondern zu einem sinnvoll optimierten Zeitpunkt. Die Steuereinheit steuert also den Ladeverlauf insbesondere den Ladebeginn so, daß das gewünschte Fahrziel erreichbar ist. Ist das nicht möglich, wird dies angezeigt. Der Fahrer kann die Arbeitsweise derThe control unit is used to communicate the parameters of the next desired driving cycle to the control unit. The control unit now has the task of optimizing the next charging cycle. If the vehicle is connected to an electrical network using a charger in order to charge the energy storage device, this will not necessarily take place immediately as usual, but at a sensibly optimized time. The control unit therefore controls the charging process, especially the start of charging, so that the desired driving destination can be reached. If this is not possible, this is displayed. The driver can change the way the
Steuereinheit beeinflussen, so daß:Control unit so that:
das Fahrzeug zu einem bestimmten Zeitpunkt eine gewünschte Reichweite hat,the vehicle has a desired range at a certain time,
das Fahrzeug (der Energiespeicher) zu einem bestimmten Zeitpunkt voll geladen ist oder
der Ladevorgang zu einem bestimmten Zeitpunkt (auch sofort) beginnt, was einer einfachen Timerfunktion
entspricht.the vehicle (the energy storage unit) is fully charged at a certain point in time or
the charging process starts at a certain time (even immediately), which is a simple timer function
corresponds.
Das Steuergerät rechnet selbständig den für den nächsten Fahrzyklus erforderlichen Energiebedarf und optimiert den
Ladezeitraum insbesondere im Hinblick auf entstehende
Energiekosten.The control unit automatically calculates the energy required for the next driving cycle and optimises the charging period, particularly with regard to the resulting
Energy costs.
Es ist entweder ein Speicherelement vorgesehen, welches
Daten über tageszeitabhängige Stromtarife enthält oder
die Steuereinheit erkennt Taktimpulse der Energieversorgungsunternehmen, die verschlüsselt Auskunft über
Stromtarife geben.Either a storage element is provided, which
Contains data on electricity tariffs depending on the time of day or
The control unit detects clock pulses from the energy supply companies, which provide encrypted information about
electricity tariffs.
Es können auch Standardfahrstrecken gespeichert und wieder mittels Kurzcode (an der Bedieneinheit) abgerufen
werden. Bei solchen Standardstrecken kann der tatsächliche Energiebedarf erfaßt werden, so daß eine sehr genaue
Vorhersage über den Energiebedarf bei erneuten Fahrten
(beispielsweise zur Arbeit) möglich ist.Standard routes can also be saved and recalled using a short code (on the control unit)
For such standard routes, the actual energy requirement can be recorded, so that a very accurate prediction of the energy requirement for subsequent trips
(for example to work) is possible.
Der Ladezyklus wird also vorteilhaft so stattfinden, daß der Bedarf an Energie bei bestimmten Fahrstrecken- und
Fahrzeugkennwerten berechnet wird und die Aufladung kostenoptimiert
gesteuert wird.The charging cycle will therefore advantageously take place in such a way that the energy requirement for certain distances and
vehicle parameters and the charging is cost-optimized
is controlled.
Die detaillierte Beschreibung eines Ausführungsbeispiels erübrigt sich nach der ausführlichen allgemeinen Erfindungsbeschreibung,
da es dem Fachmann ohne weiteres möglich ist, die Erfindung nachzuvollziehen.The detailed description of an embodiment is superfluous after the detailed general description of the invention,
since it is easily possible for a person skilled in the art to understand the invention.
