Abstract
Description
Die Erfindung betrifft eine Kraftfahrzeugbatterie nach dem Oberbegriff des Anspruchs 1. The invention relates to a motor vehicle battery according to the preamble of claim 1.
Aus der Praxis bekannte Kraftfahrzeugbatterien, wie sie zum Beispiel als Energiespeicher bzw. Traktionsbatterie in Hybridfahrzeugen oder Elektrofahrzeugen zum Einsatz kommen, verfügen typischerweise über mehrere Batteriemodule, wobei jedes Batteriemodul mehrere Batteriezellen aufweist. Um einen ordnungsgemäßen Betrieb einer Kraftfahrzeugbatterie und eine Beschädigung einer Kraftfahrzeugbatterie zu vermeiden, muss dieselbe in einem definierten Temperaturbereich betrieben werden. Bislang bereitet es Schwierigkeiten, die Temperatur einer Kraftfahrzeugbatterie, die mehrere Batteriemodule mit jeweils mehreren Batteriezellen aufweist, einfach und zuverlässig zu bestimmen. Insbesondere bereitet die Platzierung von Temperatursensoren Schwierigkeiten. Motor vehicle batteries known from practice, such as are used, for example, as energy stores or traction batteries in hybrid vehicles or electric vehicles, typically have a plurality of battery modules, each battery module having a plurality of battery cells. To avoid proper operation of a motor vehicle battery and damage to a motor vehicle battery, it must be operated within a defined temperature range. So far, it is difficult to easily and reliably determine the temperature of a motor vehicle battery having a plurality of battery modules each having a plurality of battery cells. In particular, the placement of temperature sensors presents difficulties.
Hiervon ausgehend liegt der Erfindung die Aufgabe zu Grunde eine neuartige Kraftfahrzeugbatterie zu schaffen. Diese Aufgabe wird durch eine Kraftfahrzeugbatterie gemäß Anspruch 1 gelöst. Erfindungsgemäß ist zwischen mindestens zwei Batteriezellen mindestens eines Batteriemoduls eine Blindzelle mit mindestens einem Temperatursensor angeordnet ist. Mit der Erfindung wird vorgeschlagen, zwischen zwei stapelartig hintereinander bzw. nebeneinander positionierten Batteriezellen eines Batteriemoduls eine Blindzelle zu positionieren, wobei die Blindzelle mindestens einen Temperatursensor umfasst. Auf diese Art und Weise ist es möglich, Temperaturensensoren einfach und zuverlässig in einem Stapel von Batteriezellen zu positionieren. Hiermit können die Temperatur der Batteriemodule einer Kraftfahrzeugbatterie und damit die Temperatur der Kraftfahrzeugbatterie sicher und zuverlässig bestimmt werden. Proceeding from this, the object of the invention is to provide a novel motor vehicle battery. This object is achieved by a motor vehicle battery according to claim 1. According to the invention, a dummy cell with at least one temperature sensor is arranged between at least two battery cells of at least one battery module. With the invention, it is proposed to position a dummy cell between two battery cells of a battery module positioned one behind the other or next to one another, wherein the dummy cell comprises at least one temperature sensor. In this way, it is possible to easily and reliably position temperature sensors in a stack of battery cells. Hereby, the temperature of the battery modules of a motor vehicle battery and thus the temperature of the motor vehicle battery can be determined reliably and reliably.
Vorzugsweise ist zwischen mindestens zwei Batteriezellen jedes Batteriemoduls jeweils eine Blindzelle mit jeweils mindestens einem in die jeweilige Blindzelle integrierten Temperatursensor angeordnet ist. Eine Ausgestaltung, bei welcher jedes Batteriemodul der Kraftfahrzeugbatterie mindestens eine Blindzelle mit jeweils mindestens einem in die Blindzelle integrierten Temperatur umfasst, ist besonders bevorzugt. Auf diese Art und Weise kann dann für jedes Batteriemodul der Kraftfahrzeugbatterie eine modulindividuelle Temperatur bestimmt werden, um aus den modulindividuellen Temperaturen dann die Temperatur der Kraftfahrzeugbatterie zu bestimmen. Preferably, in each case one dummy cell is arranged between at least two battery cells of each battery module, each having at least one temperature sensor integrated in the respective dummy cell. An embodiment in which each battery module of the motor vehicle battery comprises at least one dummy cell, each having at least one temperature integrated into the dummy cell, is particularly preferred. In this way, a module-specific temperature can then be determined for each battery module of the motor vehicle battery to then determine the temperature of the motor vehicle battery from the module-specific temperatures.
Nach einer vorteilhaften Weiterbildung der Erfindung weist jede Blindzelle zwei Temperatursensoren auf, nämlich einen ersten Temperatursensor zur Erfassung der Temperatur einer zu einer ersten Seite der Blindzelle positionierten Batteriezelle des jeweiligen Batteriemoduls und einen zweiten Temperatursensor zur Erfassung der Temperatur einer zu einer zweiten Seite der Blindzelle positionierten Batteriezelle des jeweiligen Batteriemoduls. Nach dieser vorteilhaften Weiterbildung der Erfindung werden über jede Bindzelle zwei Temperaturwerte erfasst, nämlich eine Temperatur einer auf der ersten Seite der Blindzelle positionierten Batteriezelle und weiterhin eine Temperatur einer auf der zweiten Seite der Blindzelle positionierten Batteriezelle. Hiermit ist dann eine noch genauere Temperaturerfassung möglich. According to an advantageous development of the invention, each dummy cell has two temperature sensors, namely a first temperature sensor for detecting the temperature of a battery cell of the respective battery module positioned to a first side of the dummy cell and a second temperature sensor for detecting the temperature of a battery cell positioned to a second side of the dummy cell of the respective battery module. According to this advantageous development of the invention, two temperature values are detected via each binding cell, namely a temperature of a battery cell positioned on the first side of the dummy cell and furthermore a temperature of a battery cell positioned on the second side of the dummy cell. Hereby an even more accurate temperature detection is possible.
Nach einer vorteilhaften Weiterbildung der Erfindung weist die Kraftfahrzeugbatterie eine Steuerungseinrichtung auf, die zur Ermittlung einer Temperatur der Kraftfahrzeugbatterie einen Mittelwert über die Messwerte aller Temperatursensor aller Blindzellen bestimmt. Diese Bestimmung der Temperatur der Kraftfahrzeugbatterie aus den Temperaturen der Batteriemodule ist einfach und zuverlässig. According to an advantageous development of the invention, the motor vehicle battery has a control device which determines an average value for the determination of a temperature of the motor vehicle battery via the measured values of all temperature sensors of all dummy cells. This determination of the temperature of the motor vehicle battery from the temperatures of the battery modules is simple and reliable.
