Ladesystem zur elektrischen Verbindung einer Ladesäule mit einem Elektroauto und Verfahren zu dessen Betrieb Charging system for the electrical connection of a charging station with an electric car and method for its operation
Die Erfindung betrifft ein System aus Ladekabel mit ein- oder beidseitigem Ladestecker. Derartige Stecker müssen ausgerichtet und orientiert in die jeweiligen Dosen bzw. Buchsen am Auto und an der Ladestation eingesteckt werden. Erst wenn die Steckverbindung hergestellt ist wird ein Ladestrom freigege¬ ben. Der Einbau derartiger Buchsen ist üblicher Weise verdeckt. Dadurch sind diese konstruktiv vor direktem Wasser geschützt. Gleichzeitig sind sie aber auch schwer einzusehen. Für Autofahrer, die bei schlechter Sicht, beispielsweise in der Dunkelheit, mit einem Ladekabel hantieren müssen, ist dies teilweise schwierig und lästig. Dies gilt sowohl für ei¬ ne Buchse an einer Ladestation als auch für eine Buchse an einem Elektroauto, welches über das Kabel an die Ladestation angeschlossen werden soll. The invention relates to a system of charging cable with one or both sides charging plug. Such plugs must be aligned and inserted into the respective cans or sockets on the car and the charging station. Only when the connector is made a charging current woks ¬ ben. The installation of such sockets is usually concealed. As a result, they are structurally protected from direct water. At the same time, they are also difficult to see. For motorists who have to deal with a charging cable in poor visibility, for example in the dark, this is sometimes difficult and annoying. This applies both to ei ¬ ne jack to a charging station and for a socket on an electric car, which is to be connected via the cable to the charging station.
Bisherige Lösungen bestehen darin, eine Taschenlampe zu ver¬ wenden. Diese Verfahrensweise ist jedoch äußerst umständlich und unbequem. Es liegt insbesondere keine standardisierte Ausrüstung vor, die sämtliche Situationen beim Betrieb eines Ladekabels berücksichtigt. Previous solutions consist in turn a flashlight to ver ¬. However, this procedure is extremely cumbersome and uncomfortable. In particular, there is no standardized equipment that takes into account all situations when operating a charging cable.
Der Erfindung liegt die Aufgabe zugrunde ein System aus Lade¬ stecker und Ladekabel zu beschreiben, welches die relevanten Bereiche beim Laden eines Elektroautos bei Dunkelheit be- leuchtet. The invention has for its object to describe a system of charging ¬ plug and charging cable, which illuminates the relevant areas when charging an electric car in the dark.
Die Lösung dieser Aufgabe geschieht durch eine erste Beleuch¬ tung für einen Bereich an einer Steckverbindung, indem mit einem Ladestecker des Ladekabels an einem Elektroauto oder an einer Ladesäule hergestellt wird, oder einer Kombination da¬ raus. Weiterhin wird durch den Einsatz einer zweiten Beleuchtung das Ladekabel selbst entlang seiner Länge bei Dunkelheit sichtbar gemacht, so dass es als Hindernis erkennbar ist. Der Erfindung liegt die Erkenntnis zugrunde, dass eine Strom¬ versorgung für die erste Beleuchtung an einem Ladestecker durch eine vom Ladestrom unabhängige Kleinstromversorgung durchführbar ist, da diese Beleuchtung zu einer Zeit notwendig ist, in der kein Ladestrom fließt. The solution to this problem is done by a first lighting ¬ tion for a range at a connector by using a charging plug of the charging cable is made on an electric car or on a charging station, or a combination there ¬ out. Furthermore, by using a second illumination, the charging cable itself is made visible along its length in the dark, so that it can be recognized as an obstacle. The invention is based on the finding that a power ¬ supply for the first lighting on a charging plug by a charge current independent small power supply is feasible, since this lighting is necessary at a time in which no charge current flows.
Die Kleinstromversorgung kann durch Batterien, Akkus, Hochleistungskondensatoren, wie SuperCaps oder ähnliches herge- stellt werden. The small power supply can be produced by batteries, rechargeable batteries, high-performance capacitors such as SuperCaps or the like.
Zur Versorgung der zweiten Beleuchtung zur Ausleuchtung entlang des Ladekabels ist vorgesehen, dass die Stromversorgung induktiv durch Auskopplung aus dem Ladestrom erfolgt. Diese induktive Art der Stromversorgung ist sehr effektiv und es werden geringe Energiemengen durch die Beleuchtung benötigt. Die Zeit des Ladevorgangs ist wesentlich länger als die Zeit zur Herstellung der Steckverbindungen. Somit steht eine effektive Beleuchtung für das Ladekabel während des Ladevor- gangs zur Verfügung. To supply the second illumination for illumination along the charging cable is provided that the power supply is made inductively by decoupling from the charging current. This inductive type of power supply is very effective and it requires small amounts of energy from the lighting. The time of charging is much longer than the time to make the connectors. Thus, effective lighting is available for the charging cable during the charging process.
Dabei ist es besonders vorteilhaft, falls Ladesäule und It is particularly advantageous if charging station and
Elektroauto nicht ausgeleuchtet sind, beide Ladestecker des Ladesystems mit einer ersten Beleuchtung zu versehen. Electric car are not illuminated to provide both charging connector of the charging system with a first lighting.
Es ist vorteilhaft, sogenannte Licht emittierende Dioden, LEDs, in einen Ladestecker einzubauen, da diese LEDs klein in der Bauform extrem lichtstark und gleichzeitig mit geringem Energieverbrauch verbunden sind. Damit ist es möglich, solche als LED ausgeführte Beleuchtung in einen Ladestecker zu integrieren . It is advantageous to install so-called light-emitting diodes, LEDs, in a charging plug, since these LEDs are small in the design extremely bright and simultaneously connected with low energy consumption. It is thus possible to integrate such lighting designed as an LED into a charging plug.
Grundsätzlich kann die erste Beleuchtung, insbesondere eine LED Beleuchtung, über eine handelsübliche Batterie versorgt werden. Bei regelmäßiger Nutzung muss die Batterie unter Umständen zeitweise ausgetauscht werden. Um dies zu vermeiden kann ein Akku (Akkumulator) eingesetzt werden. Besonders vor- teilhaft ist der Einsatz eines Superkondensators , welcher ei¬ ne hohe Leistungsdichte aufweist. In principle, the first illumination, in particular an LED illumination, can be supplied via a commercially available battery. If used regularly, the battery may need to be replaced intermittently. To avoid this, a battery (accumulator) can be used. Especially teilhaft is the use of a supercapacitor, which has ei ¬ ne high power density.
Weiterhin ist vorteilhaft, mindestens ein Element zur Ener- gieumwandlung, Energy Harvesting, einzusetzen. Hier können zum Beispiel Solarzellen, thermische Elemente oder auch me¬ chanische Generatoren als Energiequelle dienen. Besonders vorteilhaft ist die induktive Auskopplung aus einem stromfüh¬ renden Leiter, wie er hier zum Laden des Elektroautos einge- setzt wird. Wesentlich ist, dass eine wieder aufladbare Furthermore, it is advantageous to use at least one element for energy conversion, energy harvesting. Here, for example, solar cells, thermal elements or me ¬ chanic generators serve as an energy source. Especially advantageous is the inductive coupling out a stromfüh ¬ Governing manager, as he puts einge- here to charge the electric cars. It is essential that a rechargeable
Kleinstromversorgung für die erste Beleuchtung regelmäßig an eine Stromquelle gekoppelt ist um erneut nachgeladen zu wer¬ den . Jede Beleuchtung kann schaltbar sein, so dass sie bei Bedarf aus- oder einschaltbar ist. Wird das betrachtete System mit einem Helligkeitssensor gekoppelt, so kann dieser die Ein- oder Ausschaltung einer Beleuchtung je nach Bedarf, d.h. Small power supply for the first lighting is regularly coupled to a power source to recharged to who ¬ . Each lighting can be switched so that it can be switched off or switched on if necessary. If the system under consideration is coupled with a brightness sensor, it can switch on or off a lighting as required, ie
falls Umgebung keine ausreichende Beleuchtung zur Verfügung steht, die Beleuchtung einschalten. if there is insufficient lighting in the surrounding area, turn on the lights.
Besondere Vorteile beim Betrieb eines Ladesystems entspre¬ chend der Erfindung ergeben sich aus den Verfahrensmerkmalen für den Betrieb desselben. Dabei ist notwendig eine Steckver- bindung dann zu beleuchten, wenn sie hergestellt oder entkoppelt wird. Eine entsprechende erste Beleuchtung des beschrie¬ benen Ladesystems sieht vor, dass die Beleuchtung auch mit Strom versorgt wird, wenn der Ladevorgang noch nicht gestartet ist. Für diesen Fall fließt kein Ladestrom, so dass eine separate Stromversorgung für die erste Beleuchtung notwendig ist . Particular advantages in the operation of a charging system entspre ¬ accordingly the invention will emerge from the method features for the operation thereof. It is necessary to illuminate a plug connection when it is manufactured or decoupled. A corresponding first illumination of beschrie ¬ surrounded charging system provides that the lighting is supplied with power when charging is not started. In this case, no charging current flows, so that a separate power supply for the first lighting is necessary.
Falls eine Stromversorgung für die erste Beleuchtung, die als Kleinstromversorgung auszulegen ist, wieder aufladbar ausge- legt ist, kann diese durch unterschiedliche Varianten mitIf a power supply for the first lighting, which is to be designed as a low-voltage power supply, is designed to be rechargeable, it can be equipped with different variants
Strom versorgt werden. Zum Einen kann ein direkter Anschluss an Steckelemente des Ladesteckers geschehen, wobei etwa die Erdung und ein weiterer Anschluss zur Aufladung des Elektro- autos kontaktiert werden. Andere vorteilhafte Ausführungen sehen den Einsatz von Superkondensatoren vor, welche in Grenzen wieder aufladbar sind und etwa durch die Gewinnung kleiner Mengen elektrischer Energie aus Quellen wie Umgebungstem- peratur, Vibration oder Luftströmungen versorgt werden können. Die Aufladung kann im Bedarfsfall auch induktiv als Energy Harvesting während der Aufladung geschehen. Be supplied with electricity. On the one hand, there can be a direct connection to plug-in elements of the charging plug, whereby, for example, the earthing and another connection for charging the electrical connector cars are contacted. Other advantageous embodiments provide for the use of supercapacitors, which are rechargeable within limits and can be supplied by sources such as ambient temperature, vibration or air currents, for example, by obtaining small amounts of electrical energy. If necessary, charging can also be done inductively as energy harvesting during charging.
Eine Automatisierung des Ein- oder Ausschaltens der Beleuch- tung kann auch in vorteilhafter Weise mittels eines Bewe- gungs- und Neigungssensors, evtl. in Kombination mit einem Helligkeitssensor, geschehen. Die erste Beleuchtung kann ausgeschaltet werden, sobald der Ladestrom fließt oder das Einstecken detektiert worden ist. An automation of the switching on or off of the lighting can also be done advantageously by means of a movement and inclination sensor, possibly in combination with a brightness sensor. The first illumination can be switched off as soon as the charging current flows or the insertion has been detected.
Bezogen auf die Beleuchtung des Ladekabels selbst wird eine Stromversorgung für die zweite Beleuchtung zur Kennzeichnung des Ladekabels bei Dunkelheit vorzugsweise durch induktive Auskopplung aus dem Ladestrom betrieben, so dass während der Zeitdauer des Ladevorgangs eine Beleuchtung des Ladekabels vorhanden ist. Dies ist ein wesentlicher Sicherheitsaspekt in dem ein Hindernis bei Dunkelheit sichtbar gemacht wird. Relative to the illumination of the charging cable itself, a power supply for the second illumination for labeling the charging cable in darkness is preferably operated by inductive coupling out of the charging current, so that during the period of charging lighting of the charging cable is present. This is an essential safety aspect in which an obstruction is made visible in the dark.
Im Folgenden werden einzelne Komponenten des Ladesystems, welche den Rahmen der Erfindung jedoch nicht einschränken, wiedergegeben. Die Figuren zeigen im Einzelnen: In the following, individual components of the charging system, which do not limit the scope of the invention, however, reproduced. The figures show in detail:

Die Energieversorgung für die erste Beleuchtung kann relativ wartungsarm ausgeführt werden, indem sie wieder aufladbar ausgeführt wird. Dies geschieht durch den Einsatz von Akkus oder Superkondensatoren . Diese werden insbesondere durch Energieumwandlung aus der Umgebung regelmäßig nachgeladen, so dass die erste Beleuchtung 14,18 regelmäßig zur Verfügung steht. Die Ein- oder Ausschaltung der ersten Beleuchtung während der Herstellung oder auch der Entkoppelung einer Steckverbindung geschieht in Abhängigkeit von der Helligkeit der Umgebung oder auch per Hand. Die einfachste Möglichkeit, die erste Beleuchtung für den Vorgang zur Herstellung der Steck- Verbindung bereitzustellen ist der direkte Anschluss der ersten Beleuchtung an bestehende bereits vorhandene Leitungen in einem Ladestecker. The power supply for the first lighting can be carried out relatively low maintenance by running it rechargeable. This is done by using rechargeable batteries or supercapacitors. These are regularly recharged in particular by energy conversion from the environment, so that the first lighting 14,18 is available regularly. The switching on or off of the first illumination during the production or decoupling of a plug-in connection is dependent on the brightness of the environment or by hand. The easiest way to provide the first lighting for the process of producing the plug-in connection is the direct connection of the first lighting to existing existing lines in a charging plug.
Eine weitere Variante der Erfindung berücksichtigt, dass die notwendige Energie in vorteilhafter Weise über ein EnergyAnother variant of the invention takes into account that the necessary energy in an advantageous manner via an energy
Harvesting gewonnen wird. Hierzu bietet sich zum Beispiel die Nutzung von parasitären Koppeleffekten an, wobei beispielsweise eine Parallelleitung zu einem der Leiter des Ladekabels gelegt wird. Die Kopplung wirkt etwa wie eine Rogowskispule und koppelt Energie aus dem Ladevorgang ohne galvanische Ver¬ bindung aus. Eine Rogowskispule ist in die Kategorie Luftspu¬ le einzuordnen. Weitere Möglichkeiten eine Energiequelle der Umwelt zu nutzen, bieten Solarzellen, thermische Elemente bzw. Generatoren oder mechanische Generatoren. Diese Möglich- keiten sind frei kombinierbar. Harvesting is won. For this purpose, for example, offers the use of parasitic coupling effects, for example, a parallel line is placed to one of the head of the charging cable. The coupling acts somewhat like a Rogowski coil and couples energy from the charging process without galvanic Ver ¬ bond from. A Rogowski coil is classified in the category Luftspu ¬ le. Other ways to use an energy source of the environment, provide solar cells, thermal elements or generators or mechanical generators. These possibilities are freely combinable.
Eine weitere vorteilhafte Variante besteht darin, über einen einfachen Bewegungs- und Neigungssensor in Verbindung mit ei- nem Helligkeitssensor die LED-Beleuchtung automatisch bei Bedarf zu schalten. A further advantageous variant consists in using a simple movement and inclination sensor in conjunction with a A brightness sensor to switch the LED lighting automatically when needed.
Die Integration einer Beleuchtung in einem Ladekabel ohne die Steckerform als auch die Ladefunktion zu beeinträchtigen, ergibt wesentliche Vorteile. Zusätzlich kann die Energiever¬ sorgung bzw. die Energiegewinnung im Stecker oder in der nächsten Umgebung stattfinden. Figur 1 zeigt eine typische Ladesäule 1 mit einer Ladebuchse 3. Die Konstruktion ist derart ausgelegt, dass wesentliche Teile, insbesondere die stromführenden Teile wassergeschützt untergebracht sind. Dadurch sind diese zurückgebaut und in der Regel nicht sehr gut beleuchtet. Dieser Nachteil ver- stärkt sich insbesondere, falls die Ladesäule bei Nacht be¬ nutzt werden soll. The integration of lighting in a charging cable without affecting the plug shape as well as the charging function, provides significant benefits. In addition, the Energiever ¬ supply or energy production in the plug or take place in the immediate vicinity. Figure 1 shows a typical charging station 1 with a charging socket 3. The construction is designed so that essential parts, in particular the current-carrying parts are housed waterproof. As a result, these are dismantled and usually not very well lit. This disadvantage comparable strengthens particularly if the charging station be ¬ use at night should be.
Figur 2 zeigt ein Elektroauto 2 mit einer Ladebuchse, hier am Elektroauto, wobei die Abdeckung 9 aufgeklappt ist. Auch hier ist bei Nacht zur Herstellung einer Steckverbindung in der Regel eine Ausleuchtung notwendig. Figure 2 shows an electric car 2 with a charging socket, here on the electric car, the cover 9 is opened. Again, at night to produce a connector usually lighting is necessary.
Figur 3 zeigt neben dem Elektroauto 2 das Ladekabel 5 und ei¬ nen typischen Ladestecker 6. Diese weist einen Handgriff 8 auf, sowie Elemente zum Aufladen des Elektroautos. Der Lade¬ stecker 6 wird in Figur 4 näher erläutert. Figure 3 shows next to the electric car 2, the charging cable 5 and egg ¬ nen typical charging connector 6. This has a handle 8, and elements for charging the electric car. The charging ¬ plug 6 is explained in more detail in Figure 4.
Figur 4 zeigt einen typischen Ladestecker 6 mit einem Handgriff 8, welcher beispielhaft durch fünf untenliegende Steck- elemente eine Aufladung eines Elektroautos ermöglicht, wobei Bezugszeichen 10, 11, 12 die Phasen LI, L2, L3 bezeichnen. Der Anschluss 13 ist neutral. Der Anschluss 16 entspricht der Erdung. Die Stecker entsprechend der Anschlüsse 15 und 17 sind für besondere Kontrollen und Defekte vorhanden. FIG. 4 shows a typical charging plug 6 with a handle 8 which, by way of example, allows charging of an electric car by means of five plug-in elements below, reference numerals 10, 11, 12 designating the phases LI, L2, L3.

Erfindungswesentlich sind die Beleuchtungen 14 und 18, welche die erste Beleuchtung entsprechend der Erfindung darstellen. Die Auslegung durch Licht emittierende Dioden ist damit ver¬ bunden, dass derartige Beleuchtungen klein, lichtintensiv und mit wenig Stromverbrauch darstellbar und somit integrierbar sind . Essential to the invention are the illuminations 14 and 18, which represent the first illumination according to the invention. The design emitted by light-emitting diodes is therefore ver ¬ prevented that such lighting small, light-intensive and can be displayed with little power consumption and thus can be integrated.
Figur 5 zeigt schematisch die zweite Beleuchtung 7, die über die Länge des Ladekabels 5 verteilt ist. Diese Beleuchtung kann beispielsweise auch in Form von hintereinander sukzessiven ein- und ausgeschalteten Beleuchtungselementen aufgebaut sein. Wesentlich ist, dass das Ladekabel 5 schwach beleuchtet ist aber ausreichend genug um in der Dunkelheit wahrgenommen zu werden. FIG. 5 schematically shows the second illumination 7, which is distributed over the length of the charging cable 5. This lighting can also be constructed, for example, in the form of successively successive on and off lighting elements. It is essential that the charging cable 5 is dimly lit but sufficient enough to be perceived in the dark.
