weiteres Verfahren zur Strommessung ist aus der Offenlegungsschrift
Der Erfindung liegt damit die Aufgabe zu Grunde eine Anschlussvorrichtung für eine Batterie, insbesondere eine Fahrzeugbatterie der im Oberbegriff des Anspruchs 1 genannten Art zu entwickeln, bei der das gewünschte Strommessmodul nicht durch einen zusätzlichen Fertigungsschritt im Stromkreis im Bereich der Batterieklemme angeordnet werden muss. Des Weiteren sollen durch die Erfindung die Fertigungskosten einer solchen Anschlussvorrichtung reduziert werden. Ebenfalls liegt der Erfindung die Aufgabe zu Grunde, ein Verfahren zur elektrischen Strommessung in Fahrzeugen durch die erfindungsgemäße Anschlussvorrichtung zur Verfügung zu stellen. Dieses Strommessverfahren soll mit möglichst wenig Aufwand einfach und unkompliziert zu Handhaben sein. Diese Aufgaben werden erfindungsgemäß durch die im kennzeichnenden Teil des Anspruchs 1 angeführten Maßnahmen erreicht, denen folgende besondere Bedeutung zukommt. Das Verfahren zur elektrischen Strommessung in Fahrzeugen wird durch die erfindungsgemäß Anschlussvorrichtung in Anspruch 22 beschrieben.Of the Invention is thus the object of a connection device for one Battery, in particular a vehicle battery in the preamble Of the type mentioned in claim 1, in which the desired current measurement module not by an additional Manufacturing step arranged in the circuit in the battery terminal must become. Furthermore, by the invention, the production costs Such a connection device can be reduced. Also lies The invention is based on the object, a method for electrical Current measurement in vehicles by the connecting device according to the invention to disposal to deliver. This current measurement method should be simple with as little effort and easy to handle. These objects are achieved by the invention the measures specified in the characterizing part of claim 1 achieved the following special significance. The procedure for electrical current measurement in vehicles is by the connecting device according to the invention described in claim 22.
Erfindungsgemäß dient die Anschlussvorrichtung für eine Batterie, insbesondere eine Fahrzeugbatterie, um eine elektrische Verbindung zwischen einem Batteriepol und zumindest einem elektrischen Leiter herzustellen. Ebenfalls soll diese Anschlussvorrichtung aber auch den von der Batterie abgegebenen Strom erfassen, wozu die Anschlussvorrichtung ein Strommessmodul mit zumindest einem Messwiderstand und einer Messschaltung aufweist. Diese Messschaltung misst zumindest die anliegende Spannung am zugehörigen Messwiderstand. Da die Größe des Messwiderstandes bekannt ist, kann durch die anliegende Spannung und die vorbekannte Größe des Messwiderstandes der durchfließende Strom bestimmt werden, der sich nach der Gleichung I = U/R (I ≡ Strom; U ≡ Spannung; R ≡ Widerstand) berechnet. Die von der Messschaltung erfassten Messdaten werden in analoger oder digitaler Form an einer Auswerte- bzw. Steuereinheit weitergeleitet. Erfindungsgemäß ist der Messwiderstand in der Anschlussvorrichtung derartig integriert, dass die beiden zuvor genannten Elemente einteilig ausgestaltet sind. Folglich ist der Messwiderstand unlösbar in der Anschlussvorrichtung angeordnet. Die Anschlussvorrichtung weist dabei zwei vordefinierte Kontaktstellen auf, zwischen denen der Messwiderstand liegt, durch die die Messschaltung elektrisch anschließbar ist. Genau zwischen diesen beiden vordefinierten Kontaktstellen ist die Größe des Messwiderstandes vorbekannt. Somit ist es möglich, den von der Batterie abgegebenen Strom, der durch die Anschlussvorrichtung fließt, exakt zu bestimmen. Dabei versteht es sich von selbst, dass der gesamte Strom, der von der Batterie abgegeben wird, durch den Messwiderstand in der Anschlussvorrichtung fließen muss. Da der Messwiderstand in der Anschlussvorrichtung integriert ist, entfällt eine spätere Montage des Messwiderstands. Hierdurch lassen sich, wie gewünscht, die Fertigungskosten deutlich reduzieren.According to the invention, the connection device serves for a battery, in particular a vehicle battery, in order to produce an electrical connection between a battery pole and at least one electrical conductor. Likewise, this connection device should also detect the current delivered by the battery, for which purpose the connection device has a current measuring module with at least one measuring resistor and a measuring circuit. This measuring circuit measures at least the applied voltage at the associated measuring resistor. Since the size of the measuring resistor is known, can by the voltage applied and the known size of the measuring resistor by flowing current is determined, which is calculated according to the equation I = U / R (I ≡ current; U ≡ voltage; R ≡ resistance). The measured data acquired by the measuring circuit are forwarded in analogue or digital form to an evaluation or control unit. According to the invention, the measuring resistor in the connecting device is integrated in such a way that the two aforementioned elements are designed in one piece. Consequently, the measuring resistor is arranged undetachably in the connecting device. The connecting device has two predefined contact points, between which the measuring resistor is located, through which the measuring circuit is electrically connected. Exactly between these two predefined contact points, the size of the measuring resistor is already known. Thus, it is possible to accurately determine the current discharged from the battery flowing through the terminal device. It goes without saying that the entire current that is discharged from the battery must flow through the measuring resistor in the connection device. Since the measuring resistor is integrated in the connecting device, a later mounting of the measuring resistor is no longer necessary. As a result, as desired, the production costs can be significantly reduced.
Vorzugsweise Weitergestaltungen der Anschlussvorrichtungen sind in den Ansprüchen 2 bis 21 beschreiben. In dem Anspruch 22 wird das Verfahren zur elektrischen Strommessung in Fahrzeugen durch die erfindungsgemäße Anschlussvorrichtung offenbart.Preferably Further developments of the connection devices are in claims 2 to 21 describe. In the claim 22, the method for electrical Current measurement in vehicles by the connecting device according to the invention disclosed.
Eine erste grundlegende Ausführungsform der Anschlussvorrichtung geht aus den Unteransprüchen 2 bis 4 hervor. Bei der ersten grundlegenden Ausführungsform (gemäß Anspruch 2) ist der Messwiderstand durch eine Schweißverbindung in der Anschlussvorrichtung integriert. Zu diesem Zweck ist die Anschlussvorrichtung zuerst zweiteilig aufgebaut, wobei der Messwiderstand als elektrisches und mechanisches Bindeglied zwischen den beiden Teilen der Anschlussvorrichtung dient. Hierzu wird der Messwiderstand mit seiner linken Seite an dem linken Teil der Anschlussvorrichtung festgeschweißt und mit seiner rechten Seite an dem rechten Teil der Anschlussvorrichtung verschweißt. Um eine einfache und kostengünstige Schweißverbindung zu ermöglichen, ist es vorgesehen, dass der Messwiderstand über zwei parallele Flächen verfügt, an denen er links- und rechtsseitig mit den entsprechenden Teilen der Anschlussvorrichtung verschweißt wird. Aus diesem Grund eignet sich ein quaderförmiger Messwiderstand besonders. Selbstverständlich kann der Messwiderstand aber auch zylinderförmig oder andersartig ausgestaltet sein.A first basic embodiment of the Connecting device is apparent from the dependent claims 2 to 4. In the first basic embodiment (according to claim 2) is the measuring resistor through a welded joint in the connection device integrated. For this purpose, the connection device is first constructed in two parts, the measuring resistor as electrical and mechanical link between the two parts of the connection device serves. For this purpose, the measuring resistor with its left side welded to the left part of the connecting device and with its right side on the right part of the connection device welded. To a simple and inexpensive welded joint to enable it is provided that the measuring resistor has two parallel surfaces on which he left and right sides with the corresponding parts of the connection device welded becomes. For this reason, a cuboid measuring resistor is particularly suitable. Of course However, the measuring resistor can also be cylindrical or otherwise designed be.
Bei einer besonderen Ausführungsform der Anschlussvorrichtung ist die Schweißverbindung zwischen Messwiderstand und Anschlussvorrichtung bzw. Anschlussvorrichtung und Messwiderstand durch ein Elektronenstrahl- Schweißverfahren hergestellt. Das Elektronenstrahl-Schweißverfahren erzeugt nur eine sehr lokal begrenzte Erwärmung des Werkstückes im Bereich der Schweißverbindung. Solange jedoch noch keine weiteren Bauteile des Strommessmoduls an der Anschlussvorrichtung vorhanden sind, kann auch eine erhöhte Erwärmung der Anschlussvorrichtung hingenommen werden.at a particular embodiment The connection device is the welded connection between the measuring resistor and connecting device or connecting device and measuring resistor by an electron beam welding process produced. The electron beam welding process produces only one very localized warming of the workpiece in the area of the welded joint. But as long as no other components of the current measuring module At the connection device are present, also increased heating of the connection device be accepted.
Ebenfalls ist es bei einer weiteren Ausführungsform denkbar, den Messwiderstand durch eine Lötverbindung in der Anschlussvorrichtung zu integrieren. Genau wie die Schweißverbindung stellt die Lötverbindung einen elektrischen Kontakt zwischen der Anschlussvorrichtung und dem Messwiderstand her. Ebenfalls kann eine derartige Anschlussvorrichtung mit einem integrierten Messwiderstand auch mechanischen Belastungen ausgesetzt werden. Selbstverständlich kann der Messwiderstand auch durch andere Verbindungsverfahren in der Anschlussvorrichtung integriert werden.Also it is in a further embodiment conceivable, the measuring resistor by a solder joint in the connection device to integrate. Just like the weld joint, the solder joint provides an electrical contact between the connection device and the measuring resistor ago. Also, such a connection device with an integrated measuring resistor also mechanical loads get abandoned. Of course The measuring resistor can also be used by other connection methods in the connection device are integrated.
Bei der zweiten grundlegenden Ausführungsform der Anschlussvorrichtung besteht die gesamte Anschlussvorrichtung aus einem niederohmigen Material, so dass sie selbst den Messwiderstand bildet. Die Größe (gemessen in der Einheit Ohm) des Messwiderstands ist anhand der zwei vordefinierten Kontaktstellen eindeutig bekannt. Folglich ist die so konzipierte Anschlussvorrichtung nicht nur einteilig ausgestaltet, sondern auch materialeinheitlich. Bei dieser Ausgestaltung kann natürlich auch auf eine entsprechende Schweißverbindung oder Lötverbindung zwischen Messwiderstand und der übrigen Anschlussvorrichtung verzichtet werden. Die Größe des Messwiderstands kann durch die beiden vordefinierten Kontaktstellen gemessen werden. Sofern eine bestimmte Größe des Messwiderstands vorgegeben werden soll, ist dieses durch eine Verjüngung oder Erweiterung der Anschlussvorrichtung im Bereich zwischen den beiden vordefinierten Kontaktstellen möglich. Ist beispielsweise die Größe des Messwiderstands zu gering, so kann die Anschlussvorrichtung im Bereich zwischen den beiden vordefinierten Kontaktstellen durch Ausfräsungen oder Bohrungen entsprechend verjüngt werden, bis die entsprechende Größe des Widerstandswertes erreicht ist. Umgekehrt kann z.B. durch Auftragsschweißen der Bereich zwischen den beiden vordefinierten Kontaktstellen erweitert werden, wodurch sich die Größe des Messwiderstands verringern lässt. Auf jeden Fall ist nach jedem Bearbeitungsgang (ob Fräsen, Bohren oder Auftragsschweißen), der Widerstand zwischen den beiden vordefinierten Kontaktstellen zu messen.at the second basic embodiment the connection device consists of the entire connection device made of a low-resistance material, so that it forms the measuring resistor itself. The size (measured in the unit ohms) of the measuring resistor is based on the two predefined contact points clearly known. Consequently, the so-designed connection device not only one-piece, but also of the same material. In this embodiment, of course, to a corresponding welded joint or solder joint between measuring resistor and the rest Connection device can be omitted. The size of the measuring resistor can be measured by the two predefined contact points. Unless a certain size of the measuring resistor is to be given, this is by a rejuvenation or expansion the connection device in the area between the two predefined Contact points possible. For example, is the size of the measuring resistor too low, so the connection device in the range between the two predefined contact points by milling or Drilled holes accordingly until the appropriate size of the resistance value is reached. Conversely, e.g. by hardfacing the Extended range between the two predefined contact points , which increases the size of the measuring resistor reduce. In any case, after each machining cycle (whether milling, drilling or build-up welding), the resistance between the two predefined contact points to eat.
Eine weitere Variante der Anschlussvorrichtung sieht vor, dass das Strommessmodul zumindest an den beiden vordefinierten Kontaktstellen direkt durch eine Lötverbindung mit der Anschlussvorrichtung verbunden ist. So kann beispielsweise eine Leiterplatte des Strommessmoduls mit entsprechenden Gegenkontaktstellen direkt auf die Kontaktstellen der Anschlussvorrichtung gelötet werden. Durch diese elektrische Verbindung des Strommessmoduls mit den entsprechenden Kontaktstellen können mögliche Störgrößen weitestgehend eliminiert werden. Zusätzlich kann durch diese Maßnahme das Strommessmodul auch mechanisch mit der Anschlussvorrichtung verbunden werden. Selbstverständlich können auch noch zusätzliche Befestigungselemente vorgesehen sein.A further variant of the connecting device provides that the current measuring module at least at the two predefined contact points directly by a solder connection to the Anschlussvorrich connected. For example, a printed circuit board of the current measuring module can be soldered directly to the contact points of the connecting device with corresponding mating contact points. Through this electrical connection of the current measuring module with the corresponding contact points possible disturbances can be largely eliminated. In addition, by this measure, the current measuring module can also be mechanically connected to the connection device. Of course, additional fasteners may also be provided.
Bei einer gegensätzlichen Ausführungsvariante der Anschlussvorrichtung ist das Strommessmodul an den beiden vordefinierten Kontaktstellen indirekt durch Kontaktleitungen mit der Anschlussvorrichtung verbunden. Hierdurch ist es möglich, das Strommessmodul örtlich getrennt von der Anschlussvorrichtung anzuordnen. Außerdem ist die Verbindung zwischen Kontaktleitung und Anschlussvorrichtung einfacher herzustellen, da kein spezielles Lötverfahren verwendet werden muss. Allerdings ist diese Ausführungsvariante empfindlich gegenüber vorhandenen Steuergrößen.at an opposite one variant the connection device is the current measurement module at the two predefined Contact points indirectly through contact lines with the connection device connected. This makes it possible the current measurement module locally to be arranged separately from the connection device. Besides that is the connection between contact line and connection device easier to produce, since no special soldering process is used got to. However, this variant is sensitive to existing control variables.
Gemäß einer zusätzlichen Ausführungsvariante der Anschlussvorrichtung kann das Strommessmodul durch eine mechanische Befestigung am Messwiderstand oder an der Anschlussvorrichtung vorgesehen sein. Dabei kann das Strommessmodul z.B. geklebt oder verschraubt werden. Selbstverständlich sind auch andere mechanische Befestigungen denkbar.According to one additional variant the connecting device, the current measuring module by a mechanical Attachment to the measuring resistor or to the connection device provided be. The current measuring module may be e.g. glued or screwed become. Of course Other mechanical fasteners are conceivable.
Bei einer zusätzlichen Variante der Anschlussvorrichtung ist es vorgesehen, dass die Messschaltung die erfassten Messdaten über zumindest eine elektrische oder optische Signalleitung an die Auswerte- bzw. Steuereinheit weiterleitet. Über diese zusätzliche Signalleitung bzw. Signalleitungen kann ein Austausch der Messdaten oder anderer Steuerungsdaten erfolgen. Sofern eine komplette elektrische Entkopplung zwischen der Messschaltung und der nachgeordneten Auswerte- bzw. Steuereinheit gewünscht wird, sollte eine optische Datenübertragung für die erfassten Messdaten bzw. Signale eingesetzt werden.at an additional one Variant of the connection device, it is provided that the measuring circuit the acquired measurement data via at least one electrical or optical signal line to the evaluation or control unit forwards. About this additional Signal line or signal lines can exchange the measured data or other control data. Provided a complete electrical decoupling between the measuring circuit and the downstream evaluation or Control unit desired is, should be an optical data transmission for the recorded measurement data or signals are used.
Ebenfalls kann bei einer erfindungsgemäßen Anschlussvorrichtung vorgesehen sein, dass die Messschaltung wenigstens einen integrierten Schaltkreis enthält. Somit können auch komplexe Steuerungs- und Regelungsaufgaben durch die zuvor beschriebene Schaltung realisiert werden. Außerdem kann in der Regel auf standardisierte Bauteile (IC) zurückgegriffen werden, die bereits über die gewünschten Funktionen der Messschaltung verfügen.Also can in a connection device according to the invention be provided that the measuring circuit at least one integrated Circuit contains. Thus, you can even complex control and regulation tasks by the previously described circuit can be realized. Also, usually can standardized components (IC) are used, which already have the desired Functions of the measuring circuit.
Ferner kann bei einer besonderen Ausführungsform der Erfindung die Messschaltung die Temperatur als weiteren Messwert erfassen. Dabei ist es zweckmäßig, dass das Strommessmodul eine wärmeleitende Verbindung zur Oberfläche des Messwiderstands oder der Anschlussvorrichtung aufweist, um so exakt die Temperatur der Anschlussvorrichtung zu erfassen. Diese gibt nämlich einen genauen Aufschluss über die vorhandene Batterietemperatur. Da temporäre Kapazität der Batterie im Wesentlichen von deren Temperatur abhängt, spielt die Ermittlung der exakten Batterietemperatur eine wichtige Rolle. Als wärmeleitende Verbindung kann, wie bei den vordefinierten Kontaktstellen, eine Lötverbindung vorgesehen sein. Ebenfalls kann ein Temperatursensor der Messschaltung durch eine Temperaturleitpaste mit der Anschlussvorrichtung verbunden sein. Da der Messschaltung nunmehr auch die ermittelte Temperatur als Messwert vorliegt, kann eine Temperaturkorrektur der erfassten, temperaturabhängigen Messwerte anhand der ermittelten Temperatur vorgenommen werden. Folglich ist es möglich, die erfassten Messwerte möglichst exakt zu bestimmen, indem die Temperatur als Einflussgröße herausgerechnet wird.Further can in a particular embodiment the invention, the measuring circuit, the temperature as a further measured value to capture. It is appropriate that the current measuring module is a thermally conductive Connection to the surface of the measuring resistor or the connecting device, so exactly to detect the temperature of the connection device. These namely, gives a detailed explanation about the existing battery temperature. Since temporary capacity of the battery is essentially of whose temperature depends, Determining the exact battery temperature plays an important role Role. As thermally conductive Connection can, as with the predefined contact points, a solder be provided. Likewise, a temperature sensor of the measuring circuit connected by a Temperaturleitpaste with the connection device be. Since the measuring circuit now also the determined temperature is present as a measured value, a temperature correction of the detected, temperature-dependent Measured values are made on the basis of the determined temperature. Consequently, it is possible the recorded measured values as far as possible to be determined exactly by calculating the temperature as an influencing variable becomes.
Vorzugsweise kann bei einer besonderen Ausführungsform der Anschlussvorrichtung die Größe des Messwiderstands als Kalibrierwert in der Messschaltung gespeichert werden. Durch diese Maßnahme ist es möglich, die Fertigungstolleranzen des Messwiderstands, die sich in der unterschiedlichen Größe des Messwiderstands wiederspiegeln, zu berücksichtigen. Ebenfalls können Übergangswiderstände zwischen Anschlussvorrichtung und integrierten Messwiderstand erfasst werden. Nur bei einer genauen Bestimmung der Größe des Messwiderstands zwischen den beiden vordefinierten Kontaktstellen kann eine exakte Berechnung des durchfließenden Stroms stattfinden. Von daher muss jede Messschaltung auf den vorliegenden Messwiderstand eingerichtet werden. Folglich ist ein sogenannter „Off-Set" Abgleich bezüglich des vorhandenen Messwiderstands möglich.Preferably can in a particular embodiment the connection device the size of the measuring resistor stored as a calibration value in the measuring circuit. By This measure Is it possible, the manufacturing tolerances of the measuring resistor, which differ in the different Size of the measuring resistor reflect, take into account. Also, contact resistance between Connection device and integrated measuring resistor are detected. Only with an accurate determination of the size of the measuring resistor between The two predefined contact points can be an exact calculation of the flowing through Electricity take place. Therefore, each measurement circuit must be based on the present Measuring resistor can be set up. Consequently, a so-called "off-set" comparison with respect to existing measuring resistor possible.
Zu diesem Zweck ist bei einer weiteren Form der Anschlussvorrichtung vorgesehen, dass die Messschaltung über einer nicht-flüchtigen Speicher verfügt, in dem Daten, insbesondere Kalibrierwerte, Temperaturkompensationswerte, historische Messwerte und/oder Programme gespeichert sind. Durch die Verwendung eines nicht-flüchtigen Speichers kann sichergestellt werden, dass die gespeicherten Daten in der Messschaltung auch erhalten bleiben, sofern die Batterie einmal ausgetauscht werden muss oder über längere Zeitspanne keinen Strom geliefert hat.To this purpose is in a further form of the connection device provided that the measuring circuit over a non-volatile Memory has, in the data, in particular calibration values, temperature compensation values, historical readings and / or programs are stored. By the Use of a non-volatile Memory can be ensured that the stored data in the measuring circuit also be preserved, provided the battery need to be replaced once or no power over a long period of time has delivered.
Zusätzlich kann bei der erfindungsgemäßen Anschlussvorrichtung vorgesehen sein, dass die Messschaltung externe Daten, Programme oder Steuerungs- bzw. Reglungsbefehle von anderen Geräten empfängt und weiterverarbeitet. Somit ist es möglich, auch auf extern zur Verfügung stehende Daten zurückzugreifen.In addition, it can be provided in the connection device according to the invention that the measurement circuit external data, programs or control or regulation commands from other Ge received and further processed. Thus, it is possible to fall back on externally available data.
Bei einer besonderen Variante der Anschlussvorrichtung besteht der Messwiderstand im Wesentlichen aus CuMn12Ni (einer sogenannten Kupfer-Mangan-Nickel-Legierung). Diese Kupferlegierung zeichnet sich dadurch aus, dass die Temperatur keinen bzw. nur einen geringen Einfluss auf den Widerstandswert hat.at a special variant of the connection device is the measuring resistor essentially of CuMn12Ni (a so-called copper-manganese-nickel alloy). These Copper alloy is characterized by the fact that the temperature is not or has only a small influence on the resistance value.
Eine zusätzliche Ausführungsform der Anschlussvorrichtung sieht vor, dass zumindest ein Teil der Oberfläche der Anschlussvorrichtung mit Zinn versehen ist. Durch das verzinnen der Oberfläche kann die Anschlussvorrichtung gegenüber Umwelteinflüssen geschützt werden. Allerdings ist dabei zu beachten, dass der Bereich zwischen den beiden vordefinierten Kontaktstellen auf keinen Fall mit Zinn zu versehen ist.A additional embodiment the connection device provides that at least a part of surface the connecting device is provided with tin. By tinning the surface can the connection device opposite environmental influences protected become. However, it should be noted that the area between Under no circumstances should tin be added to the two predefined contact points is provided.
Vorzugsweise kann bei einer anderen Form der Anschlussvorrichtung zumindest das gesamte Strommessmodul einschließlich des Messwiderstands mit einem Kunststoffmantel umhüllt werden, wobei der Kunststoffmantel das Strommessmodul gegen mechanische und andere äußere Störeinflüsse, insbesondere Feuchtigkeit schützt. Ebenfalls kann zusätzlich zum Strommessmodul und dem Messwiderstand auch die abgehenden Leiter sowie die Signalleitungen mit dem Kunststoffmantel umhüllt werden. Durch diese Maßnahme ist gleichzeitig eine mechanische Zugentlastung der Leiter sowie der Signalleitungen möglich. Außerdem kann das Strommessmodul zusätzlich durch den Kunststoffmantel mechanisch an der Anschlussvorrichtung befestigt werden.Preferably can in another form of the connecting device at least the entire current measuring module including the measuring resistor with wrapped in a plastic sheath be, wherein the plastic sheath the current measuring module against mechanical and other external disturbances, in particular Moisture protects. Also may be additional to the current measuring module and the measuring resistor also the outgoing conductor and the signal lines are wrapped with the plastic sheath. By this measure is at the same time a mechanical strain relief of the conductors as well the signal lines possible. Furthermore can the current measuring module in addition through the plastic jacket mechanically to the connection device be attached.
Die erfindungsgemäße Anschlussvorrichtung gemäß der Ansprüche 1 bis 21 dient auch zur Durchführung des Verfahrens zur elektrischen Strommessung in Fahrzeugen.The Connecting device according to the invention according to claims 1 to 21 also serves to carry out the method for measuring electric current in vehicles.
