Description

Die Erfindung betrifft ein Fahrzeug, das ausschließlich oder zusätzlich über einen oder mehrere Elektromotoren angetrieben wird und dass zur Energieversorgung dieses Elektromotors oder dieser Elektromotoren mindestens eine wiederaufladbare Batterie und eine Lade- und Leistungselektronik mit einer integrierten Datenerfassungs- und Speichereinrichtung aufweist, die den momentanen Ladezustand sowie die in die Batterie eingespeiste Strommenge erfasst und mit einer Sendeeinrichtung, die beim Anschluss an eine Stromquelle zur Wiederaufladung einer Batterie ein codiertes Signal abgibt und kontinuierlich oder nach Abschluss des Ladevorgangs Signale sendet, welche die entnommene elektrische Strommenge betreffen. Ein solches Fahrzeug wird in den Unterlagen der DE-Patentanmeldung 10 2008 007 089.0 beschrieben.The invention relates to a vehicle that is exclusively or additionally driven by one or more electric motors and that has at least one rechargeable battery and a charging and power electronics with an integrated data acquisition and storage device for the power supply of this electric motor or these electric motors, the current state of charge and detected the amount of electricity fed into the battery and with a transmitting device, which emits a coded signal when connected to a power source for recharging a battery and continuously or after completion of the charging process sends signals concerning the withdrawn amount of electrical power. Such a vehicle will be in the documents of DE patent application 10 2008 007 089.0 described.

Idealerweise werden elektromotorisch betriebene Fahrzeuge angestrebt, in denen auf ein Verbrennungsmotor vollständig verzichtet werden kann. Der besondere Vorteil liegt in einer erheblichen Gewichtsersparnis, da sämtliche für Verbrennungsmotoren notwendigen Aggregate, wie ein Kraftstofftank, die Kraftstoffzufuhr, der Verbrennungsmotor sowie die Abgasführung einschließlich Reinigung, entfallen. In den eingangs beschriebenen Fahrzeugen kann die Batterie ohne Nachteil für den Fahrzeugbenutzer ausgetauscht und durch eine geladene Batterie ersetzt werden. Die Datenerfassungs- und Speicherungseinrichtung ermöglicht eine unmittelbare Kontrolle, welche Energie tatsächlich verbraucht worden ist, so dass der Fahrzeugbesitzer oder der Fahrzeugbenutzer mit der Tankstelle somit nur die aus der Batterie entnommene Energie abrechnet. Ähnlich wie es bei Propangasflaschen derzeit bereits praktiziert wird, kann somit verbrauchsorientiert eine Abrechnung erfolgen.Ideally Electromotive powered vehicles are sought in which to completely dispense with an internal combustion engine can. The particular advantage is a considerable weight saving, since all necessary for internal combustion engines Aggregates, such as a fuel tank, the fuel supply, the internal combustion engine as well as the exhaust system including cleaning, omitted. In the vehicles described above, the battery exchanged without detriment to the vehicle user and be replaced by a charged battery. The data collection and storage device allows immediate Control which energy has actually been consumed, so that the vehicle owner or the vehicle user with the gas station thus only the energy taken from the battery is charged. Similar as is currently practiced in propane gas bottles can thus consumption-oriented billing takes place.

In der deutschen Patentanmeldung 10 2008 007 089.0 wird die Problematik angesprochen, dass es wünschenswert ist, eine kostenneutrale Stromentnahme dadurch zu ermöglichen, dass Vorkehrungen für eine unmittelbare Abrechnung zwischen den Energieversorgungsunternehmen und dem Fahrzeugführer getroffen sind. Dies soll mittels einer Sendeeinrichtung geschehen, die gewährleistet, dass verbrauchsabhängige Stromabrechnungen unmittelbar dem Kunden zugeordnet werden können.In the German patent application 10 2008 007 089.0 addresses the problem that it is desirable to allow a cost-neutral current drain by making arrangements for direct billing between the power companies and the driver. This should be done by means of a transmitting device, which ensures that consumption-dependent electricity bills can be assigned directly to the customer.

Für eine Übergangsphase bei der Einführung von Elektrofahrzeugen ist jedoch damit zu rechnen, dass die Voraussetzungen für ein brauchbares Direktabrechnungssystem zwischen dem Energieversorgungsunternehmen und dem Endkunden nicht vorliegen. Hinzukommt, dass die Bereitschaft zur Installation solcher Direktabrechnungssysteme aus wirtschaftlicher Sicht erst dann zu erwarten ist, wenn eine genügend große Anzahl von Kunden, d. h. Besitzern bzw. Benutzern mit Elektrofahrzeugen vorliegen.For a transitional phase in the introduction of electric vehicles However, it is to be expected that the conditions for a viable direct billing system between the utility company and the end customer are not present. Add to that the readiness to install such direct accounting systems from economical View is only to be expected if a sufficiently large Number of customers, d. H. Owners or users with electric vehicles available.

Es ist daher Aufgabe der vorliegenden Erfindung, ein Fahrzeug zu schaffen, das alternativ oder zusätzlich die Möglichkeit bietet, Strommengen, die beim Laden der Fahrzeugbatterie aus einem Fremdnetz entnommen worden sind, korrekt zu erfassen.It is therefore an object of the present invention to provide a vehicle, the alternative or in addition the possibility offers, amounts of electricity that when charging the vehicle battery from a Foreign network have been taken correctly.

Diese Aufgabe wird durch ein Fahrzeug nach Anspruch 1 dadurch gelöst, dass die Speichereinrichtung einen im Fahrzeug integrierten Stromzähler umfasst, der vorzugsweise geeicht und verplombt ist. Prinzipiell haben sich geeichte und verplombte Stromzähler in Privathaushalten bewährt, da in periodischen Abständen, zumeist innerhalb von 12 Monaten jeweils Ablesungen vorgenommen werden können, die eine verbrauchsgerechte Abrechnung gestatten. So kann vor und nach der Entnahme von Strom aus einem Fremdnetz zur Wiederaufladung der Autobatterie die tatsächlich entnommene Strommenge festgestellt und korrekt auf Basis des jeweils anzurechnenden Kilowatt-Stundenpreises abgerechnet werden.These The object is achieved by a vehicle according to claim 1, characterized the storage device comprises an electricity meter integrated in the vehicle, which is preferably calibrated and sealed. In principle have become calibrated and sealed electricity meters in private households proven, since in periodic intervals, mostly readings can be made within 12 months, which allow consumption-based billing. So can before and after the removal of electricity from a foreign network for recharging the Car battery, the actual amount of electricity detected and correctly on the basis of the kilowatt-hour price to be credited be billed.

Vorzugsweise besitzt der Stromzähler eine Eingabeeinrichtung für den kWh-Preis zum Zeitpunkt des Ladevorgangs, so dass über einen integrierten Rechner unmittelbar die Kosten für die entnommene Strommenge berechnet und angezeigt werden können. Auf diese Weise können individuell die Stromtarife der Vergütungsberechnung zugrunde gelegt werden, die derjenige zahlt, der sein Stromnetz zum Wiederaufladen der Batterie zur Verfügung stellt.Preferably the electricity meter has an input device for the kWh price at the time of charging, so over an integrated calculator directly costs for the The calculated amount of electricity can be calculated and displayed. In this way can individually the electricity tariffs of the Compensation calculation are based, the one pays its power grid to recharge the battery provides.

Nach einer weiteren Ausgestaltung der Erfindung besitzt der Stromzähler einen Drucker, der die aufgezeichneten Ladedaten, insbesondere die in die Batterie eingespeiste Strommenge und die Ladezeiten sowie den zu zahlenden Strompreis ausdruckt.To a further embodiment of the invention has the electricity meter a printer that records the recorded data, in particular the into the battery fed amount of electricity and the charging times as well the price of electricity to be paid.

In der praktischen Anwendung wird vom Fahrzeugbenutzer oder dem an einer Tankstelle oder einem Parkhaus vorhandenen Bedienungspersonal der anzusetzende kWh-Verrechnungspreis in die Eingabevorrichtung eingegeben, was manuell oder mittels eines per Draht oder drahtlos gesendeten Signals geschehen kann. Im anschließenden Ladevorgang erfasst der Stromzähler insbesondere die Strommenge, woraus sich die zu zahlende Vergütung berechnen lässt. Nach Abschluss des Ladevorgangs wird vom integrierten Drucker eine Quittung ausgeworfen, welche die relevanten Daten wie Datum, Dauer und Uhrzeit des Ladevorgangs, Besitzer oder Eigentümer des für den Ladevorgang benutzten Stromnetzes auswirft. Die Vergütung kann entweder unmittelbar oder über ein summarisches Abrechnungssystem in periodischen Abständen erfolgen.In the practical application is carried out by the vehicle user or the a gas station or a parking garage existing operator of the entered kWh transfer price entered into the input device, what manually or by means of a wire or wirelessly sent Signals can happen. Detected in the subsequent charging process the electricity meter in particular the amount of electricity, from which to calculate the remuneration to be paid. To Completion of the loading process, a receipt is ejected from the integrated printer, which the relevant data such as date, duration and time of the charging process, Owner or owner of the for charging used power network ejects. The remuneration can either be immediate or via a summary settlement system in periodic Intervals are made.

Da alle für die Registrierung der entnommenen Strommenge notwendigen Einrichtungen am oder im Fahrzeug integriert sind, muss derjenige, der sein Stromnetz zum Wiederaufladen zur Verfügung stellt, keine besonderen Einrichtungen besitzen; prinzipiell kann jeder Privatperson der Stromverbrauch nach dem individuellen Stromtarif vergütet werden.There all necessary for the registration of the extracted electricity Facilities are integrated on or in the vehicle, the one which provides its power grid for recharging, have no special facilities; In principle, everyone can Private person the electricity consumption according to the individual electricity tariff be remunerated.

Alternativ ist es auch möglich anhand der einzelnen Quittungsbelege mit den Energieversorgungsunternehmen abzurechnen, die den Strom geliefert haben.alternative It is also possible based on the individual receipt documents to settle with the power companies that power Have been delivered.
