Description
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Kühlung einer Schalteinrichtung, Überstromschutzeinrichtung und/oder einer Sensoreinrichtung sowie eine Batterietrennvorrichtung und ein Batteriesystem. Die Erfindung betrifft weiterhin ein Fahrzeug, insbesondere ein Kraftfahrzeug wie Elektrokraftfahrzeug oder Hybridfahrzeug, mit dem Batteriesystem.The invention relates to a device and a method for cooling a switching device, overcurrent protection device and / or a sensor device and a battery separator and a battery system. The invention further relates to a vehicle, in particular a motor vehicle such as electric motor vehicle or hybrid vehicle, with the battery system.
Stand der TechnikState of the art
Es ist absehbar, dass sowohl bei stationären Anwendungen, zum Beispiel bei Windkraftanlagen, als auch bei mobilen Anwendungen, zum Beispiel bei Elektrokraftfahrzeugen (electric vehicles, EV) oder Hybridfahrzeugen (hybrid electric vehicles, HEV), als wiederaufladbare Energiespeicher vermehrt neue Batteriesysteme, zum Beispiel mit Lithium-Ionen-Akkumulatoren oder Nickel-Metallhybrid-Akkumulatoren, zum Einsatz kommen werden.It is foreseeable that both in stationary applications, for example in wind turbines, and in mobile applications, for example in electric vehicles (EV) or hybrid vehicles (hybrid electric vehicles, HEV), as rechargeable energy storage increasingly new battery systems, for example with lithium-ion batteries or nickel-metal hybrid batteries will be used.
Die Batteriesysteme müssen sehr hohe Anforderungen bezüglich des nutzbaren Energieinhalts, des Lade-/Entlade-Wirkungsgrads, der Zuverlässigkeit, der Lebensdauer und des unerwünschten Kapazitätsverlusts durch häufige Teilentladung erfüllen.The battery systems must meet very high requirements in terms of usable energy content, charge / discharge efficiency, reliability, life and unwanted capacity loss due to frequent partial discharge.
Ein Batteriesystem umfasst eine Vielzahl von Batteriezellen. Aufgrund ihres Zelleninnenwiderstands erwärmen sich die Batteriezellen während des Ladens und Entladens. Die Batteriezellen können in Reihe (Serie) verschaltet werden, um die elektrische Spannung zu erhöhen, und/oder parallel verschaltet werden, um den maximalen elektrischen Strom zu erhöhen. Dabei können die Batteriezellen zu Batterieeinheiten bzw. Batteriemodulen zusammengefasst werden. Beim Einsatz zum Antrieb von Fahrzeugen können beispielsweise ca. 100 Batteriezellen in Serie bzw. parallel verschaltet werden. Bei einem Hochvoltbatteriesystem kann die Gesamtspannung somit beispielsweise 450 V oder sogar 600 V betragen.A battery system includes a plurality of battery cells. Due to their internal cell resistance, the battery cells heat up during charging and discharging. The battery cells can be connected in series (series) to increase the voltage and / or connected in parallel to increase the maximum electric current. In this case, the battery cells can be combined to form battery units or battery modules. When used to drive vehicles, for example, about 100 battery cells can be connected in series or in parallel. For example, in a high voltage battery system, the total voltage may be 450V or even 600V.
Um die Sicherheit des Batteriesystems, insbesondere des Hochvoltbatteriesystems, zu gewährleisten, ist es daher erforderlich, den Stromkreis beispielsweise mittels einer Schalteinrichtung wie eines Relais, eines Schützes insbesondere eines Schaltschützes oder eines Schalters unterbrechen zu können. Die Schalteinrichtung muss hohe Ströme beispielsweise mehrere 100 A übertragen und auch sicher trennen können. Deshalb ist die Schalteinrichtung eine wichtige und kostenintensive Komponente. Kurzschlussströme können beispielsweise mit einer Überstromschutzeinrichtung wie einer Sicherung insbesondere Schmelzsicherung abgesichert sein. Die Schalteinrichtung, die Überstromschutzeinrichtung und/oder eine Sensoreinrichtung können beispielsweise in dem Batteriesystem oder einer Batterietrennvorrichtung (battery disconnect unit, BDU) angeordnet sein.In order to ensure the safety of the battery system, in particular the high-voltage battery system, it is therefore necessary to be able to interrupt the circuit, for example by means of a switching device such as a relay, a contactor, in particular a contactor or a switch. The switching device must be able to transmit high currents, for example, several 100 A and also safely disconnect. Therefore, the switching device is an important and expensive component. Short-circuit currents can be protected, for example, with an overcurrent protection device such as a fuse, in particular fuse. The switching device, the overcurrent protection device and / or a sensor device can be arranged, for example, in the battery system or a battery disconnect unit (BDU).
Somit wird in der Regel für die Auslegung der Schalteinrichtung der zu übertragende Strom entscheidend sein. Aufgrund des Kontaktwiderstands der internen Kontakte der Schafteinrichtung verursacht der übertragene Strom Wärme. Zu einem großen Teil wird diese Wärme von den internen Kontakten über die Anschlüsse (Terminals) der Schafteinrichtung und Stromschienen, die mit den Terminals verbunden sind, abgeleitet. Wenn ein hoher Strom über längere Zeit über die Schalteinrichtung übertragen wird, kann die Schalteinrichtung beschädigt werden.Thus, the current to be transmitted will usually be decisive for the design of the switching device. Due to the contact resistance of the internal contacts of the shank device, the transmitted current causes heat. To a large extent, this heat is dissipated from the internal contacts via the terminals of the shunting device and bus bars connected to the terminals. If a high current is transmitted over the switching device for a long time, the switching device may be damaged.
