Abstract
Description
Die vorliegende Erfindung betrifft ein elektrisches System bzw. Energiespeichersystem mit Mittelspannungsabgriff zur Messung der Spannung.The present invention relates to an electrical system or energy storage system with medium voltage tap for measuring the voltage.
Gattungsgemäße elektrische Systeme, insb. Energiespeichersysteme umfassen in der Regel eine elektrische Einheit bzw. eine Energiespeichereinheit und eine diese elektrische Einheit vom Umfeld elektrisch isolierende Isolationseinheit sowie eine elektrische Schnittstelle wie z. B. einen Stecker zur Herstellung elektrischer Verbindung zur elektrischen Einheit, wobei diese Schnittstelle in einer dafür vorgesehene Aussparung an der Isolationseinheit eingeführt bei Bedarf trennbar in der Isolationseinheit verrastet ist.Generic electrical systems, esp. Energy storage systems usually include an electrical unit or an energy storage unit and this electrical unit from the environment electrically insulating isolation unit and an electrical interface such. B. a plug for making electrical connection to the electrical unit, said interface is inserted in a recess provided for this purpose on the insulation unit is releasably latched in the insulation unit when required.
Die elektrische Einheit umfasst oft mehrere elektrische bzw. elektronische Komponenten. Im Falle einer Energiespeichereinheit umfasst diese in der Regel zwei oder mehrere Energiespeicherzelle, bspw. Doppelschichtkondensatoren, die zueinander in Reihe oder parallel geschaltet sind.The electrical unit often includes multiple electrical or electronic components. In the case of an energy storage unit, this usually includes two or more energy storage cell, for example. Double-layer capacitors, which are connected to each other in series or in parallel.
Wie bei meisten elektrischen Systemen bestehen bei Energiespeichersystemen Anforderungen daran, das Spannungspotential zwischen zweier Energiespeicherzellen zu messen, um unerhoffte Spannungsunterschiede zwischen den Energiespeicherzellen zu erfassen und bei Bedarf mittels geeigneten Verfahren ausgleichen zu können.As with most electrical systems, energy storage systems have requirements to measure the voltage potential between two energy storage cells in order to detect unexpected voltage differences between the energy storage cells and, if necessary, to compensate for them using appropriate techniques.
Hierzu wurde eine aus Metall- oder Metalllegierungsplatte ausgestanzte Stromschiene zum Abgreifen des Spannungspotentials verwendet, welche an der elektrischen Verbindung bzw. dem Stromleiter zwischen zweier benachbarten Speicherzellen angelötet und an einem anderen Ende mit der entsprechenden Messeinheit elektrisch verbunden wurde.For this purpose, a punched out of metal or metal alloy plate busbar for tapping the voltage potential was used, which was soldered to the electrical connection or the conductor between two adjacent memory cells and electrically connected at another end with the corresponding measuring unit.
Bedingt durch die physikalischen Eigenschaften bzw. alterungsbedingt dehnen sich die Energiespeicherzellen entlang deren Längsachse aus. So verschiebt sich auch die Kontaktstelle der Stromschiene am Stromleiter mit den sich ausdehnenden Zellen.Due to the physical properties or due to age, the energy storage cells expand along their longitudinal axis. Thus, the contact point of the busbar on the conductor shifts with the expanding cells.
Diese Eigenschaft wirkt insb. negativ auf die Energiespeichersysteme, in denen die Energiespeicherzellen zueinander in Reihe angeordnet wurden und so die Längenausdehnung bei der Zellengruppe stärker auftritt.This property has a negative effect in particular on the energy storage systems in which the energy storage cells have been arranged in series with one another and thus the length expansion in the cell group occurs more strongly.
Da die starre Stromschiene nicht durch entsprechende Verformung die Verschiebung der Kontaktstelle ausgleichen kann, unterbricht dabei oft die elektrische Verbindung zwischen der Stromschiene und dem Stromleiter.Since the rigid busbar can not compensate for the displacement of the contact point by appropriate deformation often interrupts the electrical connection between the busbar and the conductor.
Ersetzen der starren Stromschiene durch biegsame Stromkabel führt zu größerem Fertigungsaufwand und Mehrkosten, da sich die biegsamen Stromkabel sehr schwer maschinell in das Energiesystem verlegen lassen.Replacing the rigid busbar with flexible power cables leads to greater production costs and additional costs, since the flexible power cables can be moved into the energy system very easily by machine.
Alternative Lösung mit einer Leiterplatte mit gelöteten Kontakten zwischen zweier Energiespeicherzellen zum Spannungsabgriff führt ebenfalls zu einem höheren Fertigungsaufwand und somit Mehrkosten.Alternative solution with a printed circuit board with soldered contacts between two energy storage cells for voltage tap also leads to a higher production cost and thus additional costs.
Die Aufgabe der vorliegenden Erfindung liegt somit darin, ein elektrisches System bzw. Energiesystem mit Mittelspannungsabgriff zur Messung der Mittelspannung bereitzustellen, welches keinen der oben genannten Nachteile aufweist.The object of the present invention is thus to provide an electrical system or energy system with medium voltage tap for measuring the medium voltage, which has none of the above-mentioned disadvantages.
Die Aufgabe wird mit einem elektrischen System mit Merkmalskombination gemäß Anspruch 1 bzw. mit einem Energiespeichersystem mit Merkmalskombination gemäß Anspruch 5 gelöst.The object is achieved with an electrical system with feature combination according to claim 1 or with an energy storage system with feature combination according to claim 5.
Demnach wird eine einfache und sichere Gestaltung eines Mittelspannungsabgriffs zur Messung des Spannungspotentials an der elektronischen Einheit des Systems bzw. zwischen den Energiespeicherzellen des Energiespeichersystems erfindungsgemäß mit einem elektrisch leitenden Kontaktpin ermöglicht, welcher an dem Stromleiter zwischen zweier benachbarten Energiespeicherzellen der elektrischen Einheit des erfindungsgemäßen Systems angeordnet ist. Zudem weist das elektrische System einen den Kontaktpin aufnehmenden Stecker mit einem Steckergehäuse zur Herstellung der elektrischen Verbindung vom Kontaktpin, also vom Mittelabgriff der beiden Energiespeicherzellen, zu einer elektrischen Vorrichtung bspw. Spannungsmessvorrichtung auf.Accordingly, a simple and secure design of a medium voltage tap for measuring the voltage potential at the electronic unit of the system or between the energy storage cells of the energy storage system according to the invention with an electrically conductive contact pin allows, which is arranged on the current conductor between two adjacent energy storage cells of the electrical unit of the system according to the invention , In addition, the electrical system has a plug receiving the contact pin with a plug housing for producing the electrical connection from the contact pin, that is from the center tap of the two energy storage cells, to an electrical device, for example, voltage measuring device.
Zur Aufnahme des Steckers wird die Isolationseinheit mit einer Aussparung versehen, in die der Stecker einplatziert werden kann. Die Isolationseinheit kann bspw. ein Gehäuse für die elektrische Einheit bzw. die Energiespeicherzellen zum Schutz vor den Umfeldeinflüssen sein, aber auch eine Trennschicht zwischen der elektrischen Einheit bzw. den Energiespeicherzellen und dem eigentlichen schützenden Gehäuse sein. Die Aussparung weist dabei an zwei zueinander gegenüber liegenden Längskanten jeweils ein im Wesentlichen parallel zur Längsrichtung der elektrischen Einheit verlaufendes erstes Rastmittel bspw. eine einstückig ausgeformte Rastnut auf. Das Steckergehäuse weist an den beiden den Längskanten der Aussparung gerichteten Seitenwänden jeweils ein mit jeweils einem der beiden ersten Rastmittel korrespondierenden zweiten Rastmittel bspw. Rastnase, Rastfeder auf.To accommodate the plug, the insulation unit is provided with a recess into which the plug can be placed. The insulation unit may, for example, be a housing for the electrical unit or the energy storage cells for protection against the environmental influences, but also a separating layer between the electrical unit or the energy storage cells and the actual protective housing. The recess has in this case at two mutually opposite longitudinal edges in each case one substantially parallel to the longitudinal direction of the electrical unit extending first locking means, for example. An integrally formed locking groove. The plug housing has at the two side walls, which are directed towards the longitudinal edges of the recess, in each case one second latching means, corresponding respectively to one of the two first latching means, for example latching lug, latching spring.
Nach dem Einführen des Steckers in die Aussparung der Isolationseinheit bzw. nach dem Einstecken des Kontaktpins in den Stecker rasten die zweiten Rastmittel in die jeweiligen ersten Rastmittel ein und bilden so eine stabile jedoch gezielt trennbare Rastverbindung zwischen dem Stecker und der Isolationseinheit, wobei die ersten und zweiten Rastmittel zueinander so angepasst sind, dass bei Verschiebung des Kontaktpins bzgl. der Isolationseinheit infolge der Längenausdehnung bei der elektrischen Einheit der Stecker sich samt dem Kontaktpin entlang der Rastverbindung bzw. der ersten Rastmittel in Längsrichtung der elektrischen Einheit gleitet und so die Verschiebung des Kontaktpins infolge der Längenausdehnung bei der elektrischen Einheit ausgleicht. After insertion of the plug into the recess of the insulation unit or after inserting the contact pins in the connector, the second locking means engage in the respective first locking means and form a stable but selectively separable locking connection between the plug and the insulation unit, wherein the first and The second locking means are adapted to each other so that upon displacement of the contact pin with respect to the insulation unit due to the longitudinal extent in the electrical unit of the plug along with the contact pin along the locking connection or the first locking means in the longitudinal direction of the electrical unit slides and so the displacement of the contact pins due compensates for the length expansion in the electrical unit.
Die ersten Rastmittel an der Isolatoreinheit sind mit den korrespondierenden zweiten Rastmittel am Steckergehäuse so angepasst und stabil ausgeführt, dass diese sich nicht voneinander lösen, wenn sich der Stecker entlang der ersten Rastmittel gleitet. Der Stecker kann also nur durch gezieltes Entriegeln der Rastverbindung zwischen den ersten und zweiten Rastmitteln vom Isolator bzw. von dem Kontaktpin getrennt werden.The first locking means on the insulator unit are adapted to the corresponding second locking means on the connector housing and made stable that they do not dissolve when the connector slides along the first locking means. The plug can therefore only be separated from the contact pin by selective unlocking of the latching connection between the first and second latching means.
Vorzugsweise sind die beiden ersten Rastmittel als einstückig ausgeformte und im Wesentlichen parallel zur Längsrichtung der elektrischen Einheit somit auch parallel zur Richtung der Ausdehnung verlaufende Rastnut ausgeführt.Preferably, the two first locking means are designed as integrally formed and thus substantially parallel to the longitudinal direction of the electrical unit also extending parallel to the direction of expansion locking groove.
Zudem sind die mit den ersten Rastmitteln versehenen Längskanten der Aussparung bzw. die Aussparung in Längsrichtung breiter ausgeführt als die mit den zweiten Rastmitteln versehenen Seitenaußenwände des Steckergehäuses, sodass zwischen dem Stecker und der Aussparung entlang der Längskanten Freiräume für ungehinderte Verschiebung vom Stecker entstehen.In addition, the provided with the first locking means longitudinal edges of the recess or the recess in the longitudinal direction are made wider than the second locking means provided side outer walls of the plug housing, so that arise between the plug and the recess along the longitudinal edges of open spaces for unimpeded displacement of the plug.
Ein Beispiel eines derartigen elektrischen Systems ist ein Energiespeichersystem mit zwei zueinander in Reihe beschaltete Energiespeicherzellen, wobei die Energiespeicherzellen gemeinsam die elektrische Einheit bilden und der Pluspol einer ersten Energiespeicherzelle mit dem Minuspol der zweiten Energiespeicherzelle über ein elektrisch leitendes Verbindungsmittel bzw. Stromleiter elektrisch verbunden ist, wobei an diesem Verbindungsmittel der Kontaktpin erfindungsgemäß angeordnet ist. Derartige Energiespeichersysteme finden ihre Anwendung insb. als Energiequelle für Bordnetz in Fahrzeugen bzw. als Energiequelle für Elektroantrieb in Hybrid-, oder Elektrofahrzeugen.An example of such an electrical system is an energy storage system having two energy storage cells connected in series with each other, wherein the energy storage cells together form the electrical unit and the positive pole of a first energy storage cell is electrically connected to the negative pole of the second energy storage cell via an electrically conductive connection means or conductor is arranged according to the invention at this connection means of the contact pin. Such energy storage systems find their application esp. As an energy source for vehicle electrical system in vehicles or as an energy source for electric drive in hybrid or electric vehicles.
