Abstract
Description
Die Erfindung betrifft eine wiederaufladbare Batterie mit mehreren Batterieelementen.The invention relates to a rechargeable battery with a plurality of battery elements.
Stand der TechnikState of the art
Derartige wiederaufladbare Batterien sind grundsätzlich bekannt. Unter dem Begriff wiederaufladbare Batterie ist im Zusammenhang dieser Patentanmeldung – dem allgemeinen Sprachgebrauch angepasst – ein Akkumulator zu verstehen, der über viele Zyklen elektrisch geladen und wieder entladen werden kann. Eine solche Batterie umfasst üblicherweise mehrere einzelne galvanische Zellen, den Batteriezellen, die eine für die verwendete Materialkombination der Zelle charakteristische Spannung liefern. Um aus diesen Batteriezellen eine Batterie aufzubauen, die die geforderten Leistungs- und Energiemengen liefern kann, werden die einzelnen Batteriezellen elektrisch in Serie und/oder parallel geschaltet. Ein Batterieelement der Batterie ist eine einzelne Batteriezelle oder eine kompakte Batterieanordnung miteinander elektrisch verschalteter Batteriezellen.Such rechargeable batteries are known in principle. The term rechargeable battery is in the context of this patent application - adapted to common usage - an accumulator to understand that can be electrically charged and discharged again over many cycles. Such a battery usually comprises a plurality of individual galvanic cells, the battery cells, which supply a voltage characteristic of the combination of materials used in the cell. In order to build a battery from these battery cells, which can deliver the required amounts of power and energy, the individual battery cells are electrically connected in series and / or in parallel. A battery element of the battery is a single battery cell or a compact battery assembly of electrically interconnected battery cells.
Der Temperaturbereich, in dem solche Batterien betrieben werden können, ist in der Regel begrenzt. Außerhalb des Temperaturbereiches, insbesondere bei zu hohen Temperaturen, kann es zu chemischen Zersetzungsreaktionen innerhalb der Batteriezellen kommen. Bei Lithium-Ionen-Batterien beispielsweise wird dabei nicht nur das verwendete chemische Aktivmaterial zur Speicherung der Lithium-Ionen in den Elektroden exotherm umgewandelt, es wird dabei auch die in der Zelle gespeicherte elektrische Energie in Form von Wärme freigesetzt. Dieser Vorgang wird als „thermal Runaway” bezeichnet. Zu solch einem thermal Runaway kann es beispielsweise durch einen Materialfehler kommen.The temperature range in which such batteries can be operated is usually limited. Outside the temperature range, in particular at too high temperatures, chemical decomposition reactions can occur within the battery cells. In the case of lithium-ion batteries, for example, not only is the active chemical material used for the storage of lithium ions in the electrodes exothermically converted, it also releases the electrical energy stored in the cell in the form of heat. This process is called "thermal runaway". For example, such a thermal runaway may be due to a material defect.
Es ist grundsätzlich bekannt, die Wärmeströme innerhalb der Batterie sowie die Wärmeströme in die Batterie hinein oder aus der Batterie heraus zu steuern, so dass die Batterie innerhalb ihres zugelassenen Temperaturbereiches betrieben wird.It is generally known to control the heat flows within the battery as well as the heat flows into or out of the battery so that the battery is operated within its allowed temperature range.
Die
Offenbarung der ErfindungDisclosure of the invention
Gegenstand der Erfindung ist eine wiederaufladbare Batterie, umfassend mehrere nebeneinander angeordnete Batterieelemente und mindestens ein Wärmeisolationsmittel, wobei das mindestens eine Wärmeisolationsmittel zwischen zwei benachbart angeordneten Batterieelementen zum Reduzieren eines Wärmetransports zwischen den benachbarten Batterieelementen angeordnet ist.The invention relates to a rechargeable battery, comprising a plurality of juxtaposed battery elements and at least one heat insulating means, wherein the at least one heat insulating means between two adjacently arranged battery elements for reducing a heat transfer between the adjacent battery elements is arranged.
Die Anordnung eines Wärmeisolationsmittels zwischen zwei benachbart angeordneten Batterieelementen ermöglicht es, das eine Batterieelement vor einer Überhitzung des anderen Batterieelementes zu schützen. Insbesondere ein „thermal Runaway” weiterer Zellen und eine damit verbundene Kettenreaktion lassen sich auf diese Weise effektiv verhindern.The arrangement of a heat insulating means between two adjacently arranged battery elements makes it possible to protect the one battery element from overheating of the other battery element. In particular, a "thermal runaway" of other cells and an associated chain reaction can be effectively prevented in this way.
Als Wärmeisolationsmittel eignen sich grundsätzlich Materialien mit einem niedrigen Wärmeleitfähigkeit λ, vorzugsweise λ < 1 W/mK, und einer genügend hohen Temperaturstabilität, um bei einer Überhitzung nicht zerstört zu werden. Als Materialien bevorzugt sind Hochtemperaturkunststoffe, Keramiken oder Materialien auf der Basis von Glasfasern.As thermal insulation materials are in principle materials with a low thermal conductivity λ, preferably λ <1 W / mK, and a sufficiently high temperature stability, so as not to be destroyed in an overheating. Preferred materials are high-temperature plastics, ceramics or materials based on glass fibers.
Vorzugsweise umfasst die Batterie zusätzlich eine Wärmetransporteinrichtung zum Kühlen der Batterie und mindestens eine Wärmeleiteinrichtung zum innerhalb der Batterie erfolgenden Wärmetransfer mittels Wärmeleitung zwischen den Batterieelementen und der Wärmetransporteinrichtung.Preferably, the battery additionally comprises a heat transport device for cooling the battery and at least one heat conduction device for heat transfer occurring within the battery by means of heat conduction between the battery elements and the heat transport device.
Die Wärmeleiteinrichtung oder die Wärmeleiteinrichtungen ermöglichen einen Batterie-internen Wärmetransfer zwischen den Batterieelementen und der Wärmetransporteinrichtung. Die Wärmetransporteinrichtung ist eine der Batterie zugeordnete Einrichtung zur Zufuhr von Wärme zu der Batterie und/oder zur Abfuhr der Wärme von der Batterie.The heat conducting device or the heat conducting devices allow a battery-internal heat transfer between the battery elements and the heat transport device. The heat transport device is a device associated with the battery for supplying heat to the battery and / or for dissipating the heat from the battery.
Die Wärmeleiteinrichtung besteht – zumindest teilweise – aus einem Material mit hoher thermischer Leitfähigkeit, vorzugsweise aus einem Metall mit geringem elektrischem Widerstand. Hierfür eignet sich insbesondere Kupfer oder Aluminium.The heat conducting device consists - at least in part - of a material with high thermal conductivity, preferably of a metal with low electrical resistance. For this purpose, in particular copper or aluminum is suitable.
Die Wärmetransporteinrichtung bildet bevorzugt einen die Batterieelemente tragenden Batteriesockel. Durch die zusätzliche Funktion der Wärmetransporteinrichtung als Sockel wird eine kompakte und gewichtsreduzierte Bauweise der Batterie erreicht. Des Weiteren weist die Wärmetransporteinrichtung insbesondere einen Temperier-Körper, beispielsweise einen Temperier-Körper mit Temperier-Rippen, auf.The heat transport device preferably forms a battery base carrying the battery elements. Due to the additional function of the heat transport device as a base, a compact and weight-reduced design of the battery is achieved. Furthermore, the heat transport device in particular a tempering body, for example, a tempering body with tempering ribs, on.
Des Weiteren ist bevorzugt, dass die Batterie zusätzlich eine Spannvorrichtung und/oder eine von dem Batterieelement und der Wärmeleiteinrichtung gebildete Spannahordnung umfasst, die das Batterieelement und die Wärmeleiteinrichtung gegeneinander verspannt.Furthermore, it is preferred that the battery additionally has a tensioning device and / or one of the Spannahordnung formed the battery element and the heat conducting device, which braces the battery element and the heat conducting device against each other.
Durch den beim Verspannen entstehenden Druck im Kontaktbereich zwischen einem Batterieelement und einer Wärmeleiteinrichtung kann der thermische Übergangswiderstand zwischen Wärmeleiteinrichtung und Batterieelement gering gehalten werden. Der von der Spannvorrichtung und/oder der Spannanordnung erzeugte Spanndruck ist dabei bevorzugt so auf die Wärmeausdehnung des Batterieelements und der Wärmeleiteinrichtung abgestimmt, dass er im gesamten Temperatur-Arbeitsbereich der Batterie aufrechterhalten bleibt.Due to the pressure arising in the contact area between a battery element and a heat conducting device during clamping, the thermal contact resistance between the heat conducting device and the battery element can be kept low. The clamping pressure generated by the clamping device and / or the clamping arrangement is preferably tuned to the thermal expansion of the battery element and the heat conducting device that it is maintained throughout the temperature working range of the battery.
Weiterhin ist bevorzugt, dass – zumindest in einem Bereich – zwischen mindestens einem Batterieelement und mindestens einer mit diesem Batterieelement verspannten Wärmeleiteinrichtung und/oder zwischen zwei Wärmeleiteinrichtungen mindestens ein elektrisch isolierendes Wärmeleitelement angeordnet ist. Das Wärmeleitelement (auch Wärmeleitpad genannt) ist elektrisch isolierend, bevorzugt zusätzlich auch thermisch leitfähig. Es ist insbesondere eine Silikongummi-Folie, bevorzugt mit einer Glasfasergewebe-Einlage, eine Glimmerscheibe, eine Keramikscheibe, vorzugsweise aus einer Aluminiumoxidkeramik, eine Silikonmatte und/oder eine Kunststofffolie, insbesondere eine Kaptonfolie. Die Kunststofffolie weist bevorzugt eine Paraffin-Beschichtung zur Füllung von mit Luft gefüllten Hohlräumen durch Aufschmelzen im Betrieb und/oder mit einer selbstklebenden Beschichtung auf.Furthermore, it is preferred that - at least in one area - between at least one battery element and at least one thermally conductive device clamped with this battery element and / or at least one electrically insulating heat-conducting element is arranged between two heat-conducting devices. The heat-conducting element (also called heat-conducting pad) is electrically insulating, preferably additionally also thermally conductive. It is in particular a silicone rubber film, preferably with a glass fiber fabric insert, a mica disk, a ceramic disk, preferably of an aluminum oxide ceramic, a silicone mat and / or a plastic film, in particular a Kapton film. The plastic film preferably has a paraffin coating for filling air-filled cavities by melting during operation and / or with a self-adhesive coating.
Die wiederaufladbare Batterie ist insbesondere eine Batterie für ein Hybridfahrzeug und/oder ein Elektrofahrzeug. Die Batterie ist bevorzugt eine Nickel-Metallhydrid-Batterie oder eine Lithium-Ionen-Batterie, d. h., die Batterieelemente sind bevorzugt Nickel-Metallhydrid-Batteriezellen oder eine Lithium-Ionen-Batteriezellen.The rechargeable battery is in particular a battery for a hybrid vehicle and / or an electric vehicle. The battery is preferably a nickel metal hydride battery or a lithium ion battery, i. h., The battery elements are preferably nickel-metal hydride battery cells or a lithium-ion battery cells.
