Abstract

The invention substantially relates to a combination of existing technologies or technologies that can be found in the introduction for energy transmission and storage for e-cars using a novel energy-exchanging infrastructure at street intersections, an improved vehicle range being achieved by means of a more frequent high-energy recharge using said infrastructure. With an appropriate frequency of such devices at intersections, at least smaller secondary slow-charging energy stores can be used in the vehicles. Furthermore, the control infrastructure of such intersections can also easily be used for detecting traffic density and for influencing traffic.

Description

Beschreibung description
System zur kurzfristigen Ladung von elektrisch betriebenen Fahrzeugen System for short-term charging of electrically operated vehicles
Die Erfindung betrifft ein System zur induktiven Ladung von elektrisch betriebenen Fahrzeugen. The invention relates to a system for the inductive charging of electrically operated vehicles.
Die Reichweite elektrischer Fahrzeuge (e-Cars) ist bislang maßgeblich durch die eingeschränkte Kapazität, das hohe Ge¬ wicht und langsame Wiederaufladung von elektrischen Energiespeichern beschränkt. Um die Reichweite und die maximale Nut¬ zungsdauer des e-Cars im Rahmen der typischen Anforderungen des Individualverkehrs zu halten, ist eine große Speicherka- pazität mitzuführen, die das Gewicht erhöht, die Zuladung be¬ grenzt und zudem eine hohe Ladezeit zur Folge hat. The range of electric vehicles (e-cars) has been largely limited by the limited capacity, the high Ge ¬ weight and slow recharge of electrical energy storage. To keep the range and the maximum groove ¬ useful life of e-cars as part of the typical requirements of individual, a large Speicherka- be kept capacity, which increases the weight of the payload be limited ¬ and also has a high load time result.
Es sind bisher bspw. Konzepte zum schnellen Austausch vollständiger Akkumulatorsätze bekannt. So far, for example, concepts for the rapid replacement of complete accumulator sets are known.
Darüber hinaus existieren feste Ladestationen für e-Cars, entweder in privaten Einrichtungen oder an öffentlichen Plätzen mit unterschiedlichen Abrechungsverfahren . Ein Anschluss an diese Stationen erfolgt in der Regel über ein Elektro- Kabel - es ist aber, im Falle einer Wechselstromversorgung, auch eine induktive Kopplung mit anschließender Gleichrichtung im Fahrzeug denkbar. In addition, there are fixed charging stations for e-cars, either in private facilities or in public places with different billing procedures. A connection to these stations is usually via an electric cable - but it is, in the case of an AC power supply, also an inductive coupling with subsequent rectification in the vehicle conceivable.
Die der Erfindung zu Grunde liegende Aufgabe besteht nun dar- in, ein System zur kurzfristigen Ladung von elektrisch betriebenen Fahrzeugen anzugeben, bei dem die Reichweite dieser Fahrzeuge mit möglichst geringem Gesamtaufwand The object underlying the invention now consists in specifying a system for short-term charging of electrically operated vehicles, in which the range of these vehicles with the lowest possible total expenditure
erhöht wird. Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 erfindungsgemäß gelöst. Die weiteren Ansprüche betreffen be¬ vorzugte Ausgestaltungen der Erfindung. Die Erfindung betrifft im Wesentlichen eine Kombination existierender bzw. in der Einführung befindlicher Technologien zur Energieübertragung und Speicherung für sogenannte e-Cars mit einer neuen Infrastruktur zum Energieaustausch an Straßenkreuzungen mit der eine Verbesserung der Fahrzeugreichweite durch häufigere hochenergetische Nachladung erreicht wird. Bei entsprechender Dichte derartiger Einrichtungen an Kreuzungen können zudem kleinere sekundäre langsam ladende Energiespeicher in den Fahrzeugen eingesetzt werden. Darüber hinaus kann die Steuerungsinfrastruktur solcher Kreuzungen auch leicht zusätzlich zur Verkehrsdichteerkennung und Verkehrsbeeinflussung herangezogen werden. is increased. This object is achieved by the features of claim 1 according to the invention. The other claims relate to ¬ preferred embodiments of the invention. The invention relates in essence to a combination of existing or in the introduction of technologies for energy transmission and storage for so-called e-cars with a new infrastructure for energy exchange at road intersections with the improvement of the vehicle range is achieved by more frequent high-energy recharge. With appropriate density of such facilities at intersections also smaller secondary slow-charging energy storage can be used in the vehicles. In addition, the control infrastructure of such intersections can also be easily used in addition to traffic density detection and traffic control.
Nachfolgend wird die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. The invention will be explained in more detail with reference to embodiments shown in the drawing.
Dabei zeigen: Showing:
Figur 1 eine Übersichtsdarstellung zur Erläuterung einer erfindungsgemäßen kurzfristigen Ladung von elektrischen Fahrzeugen im Bereich einer Straßenkreuzung und Figure 1 is an overview view for explaining a short-term charge according to the invention of electric vehicles in the area of a road intersection and
Figur 2 eine Prinzipdarstellung zur Erläuterung des Aufbaus und der Funktionsweise eines entsprechenden Sys¬ tems . Figure 2 is a schematic diagram for explaining the structure and operation of a corresponding system sys ¬ tems.
Figur 1 zeigt eine Straßenkreuzung K als Energieaustauschplatz, die in den Abbrems-, Halte- und Beschleunigungsberei- chen eingelassene Induktionsvorrichtungen 1 mit jeweils einer Vielzahl von Induktionszonen 3 aufweist und in deren Bereich sich beispielhaft ein elektrisch betriebenes Fahrzeug bzw. ein e-Car C mit einem schnellladefähigen elektrischen Energiespeicher 2 befindet. FIG. 1 shows a road intersection K as an energy exchange station, which has induction devices 1, each with a plurality of induction zones 3, embedded in the braking, holding and acceleration areas and in whose area there is an electrically operated vehicle or an e-car C, by way of example a fast-charging electrical energy storage 2 is located.
Eine solche Straßenkreuzung K als Energieaustauschplatz bietet e-Cars C elektrische Energie an, um ihre schnellladefähi- gen Speicher aufzufüllen und/oder diese beim Beschleunigen im kreuzungsnahen Bereich zu unterstützen. Such a road intersection K as an energy exchange station offers e-cars C electrical energy to their fastladefähi- replenish memory and / or support them during acceleration in the cross-section area.
Durch die schnellladefähigen Speicher in den e-cars wird vor- teilhafter Weise vermieden, dass letztere auf Energie aus langsam ladenden elektrischen Speichern, z.B. elektrochemischen Akkumulatoren, zurückgreifen müssen. Diese nur in länger dauernden Haltephasen erneuerbare Energie aus den Akkumu¬ latoren steht dadurch noch mehr allein für Fahrabschnitte oh- ne Zwischenlademöglichkeiten zur Verfügung, wodurch die Gesamtreichweite des e-cars vergrößert wird. The fast-charging memory in the e-cars advantageously prevents the latter from having to resort to energy from slow-charging electrical stores, eg electrochemical accumulators. This renewable only prolonged holding phases energy from the Akkumu ¬ simulators is thus even more alone travel sections oh- ne interim charging options are available, making the total range of e-cars is increased.
Figur 2 zeigt eine Prinzipdarstellung zur Erläuterung des Aufbaus und der Funktionsweise eines entsprechenden Systems. Figure 2 shows a schematic diagram for explaining the structure and operation of a corresponding system.
Hierbei weist das elektrisch betriebene Fahrzeug C eine Lade¬ steuereinheit 4 auf, die von einer jeweiligen Induktionszone 3 der in den Abbrems-, Halte- und Beschleunigungsbereichen eingelassene Induktionsvorrichtungen 1 im Bereich unterhalb des Fahrzeugs C eine Lokalisationskennung 6 empfängt. In this case, the electrically powered vehicle C to a charging ¬ control unit 4 which receives from a respective induction zone 3 of embedded in the deceleration, acceleration and holding areas induction devices 1 in the area below the vehicle C localization identifier. 6
Die Ladesteuereinheit 4 des Fahrzeugs C leitet die Lokalisa¬ tionskennung 6 zusammen mit eigenen Identifikationsmerkmalen des Fahrzeugs kryptographisch gesichert an einen Authentifi- zierungs- und Abrechnungsdienst 9 weiter, der, nach erfolg¬ reicher Authentifizierung des Fahrzeuges, eine Kreuzungssteu¬ erung 5 über ein Instruktionssignal 10 derart instruiert, dass der jeweilige Induktionsabschnitt 3 über eine Ansteuer¬ leitung 11 freigegeben wird und dass über ein Anforderungs- signal 12 durch den Authentifizierungs- und Abrechnungsdienst 9 die übertragene Energie erfasst bzw. berechnet wird. The charging control unit 4 of the vehicle C passes the Lokalisa ¬ tion identifier 6 together with its own identification characteristics of the vehicle cryptographically secured zierungs- to a Authentifi- and settlement 9 further that, after successful ¬ richer authentication of the vehicle, a Kreuzungssteu ¬ augmentation 5 by an instruction signal 10 instructed so that the respective induction section 3 is released via a Ansteuer ¬ line 11 and that via a request signal 12 by the authentication and accounting service 9, the transmitted energy is detected or calculated.
Die Abschnitte 3 sind hierbei kleiner als Fahrzeuglängen zu wählen, um diesen eine exakte Lokalisation und der Kreuzungs- Steuerung 5 eine präzise Kontrolle und Messung des Energie¬ austausches zu ermöglichen. The sections 3 are in this case smaller than vehicle lengths to choose to allow them an exact localization and the intersection control 5 precise control and measurement of energy ¬ exchange.
Das Weiterleiten der Lokalisationskennung 6 und der Identifikationsmerkmale des Fahrzeugs erfolgt dabei in einer ersten Ausführungsvariante per lokaler Funkübertragung als Teil der Kreuzungsinfrastruktur, z.B. Wireless LAN, in einer zweiten Ausführungsvariante über eine Mobilfunkverbindung 7, z.B. über UMTS, oder in einer dritten Ausführungsvariante durch Anlegen eines entsprechend modulierten magnetischen Gegenfei des 8 an die betreffende Induktionszone 3 und somit eine di¬ rekte Rückmeldung über die Ansteuerleitung 11 zur Kreuzungssteuerung 5. The forwarding of the localization identifier 6 and the identification features of the vehicle takes place in a first Embodiment variant by local radio transmission as part of the intersection infrastructure, eg wireless LAN, in a second embodiment via a mobile phone connection 7, eg via UMTS, or in a third embodiment by applying a correspondingly modulated magnetic Gegenfei 8 to the relevant induction zone 3 and thus a di ¬ direct feedback via the control line 11 to the intersection controller. 5
Die übertragene Lokalisationskennung 6 ist kryptographisch gesichert und variiert optional ständig über der Zeit, um ei nen Missbrauch zu verhindern. The transmitted localization identifier 6 is cryptographically secured and optionally varies constantly over time to prevent misuse.
