Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte elektrochemische Energiespeicherzelle, insbesondere eine Batterie zu einer Anwendung in einem Fahrzeug, anzugeben, welche einfach und kostengünstig herstellbar ist.Of the Invention is based on the object, an improved electrochemical Energy storage cell, in particular a battery to an application in a vehicle, specify which is easy and inexpensive can be produced.
Die erfindungsgemäße Batterie, welche insbesondere zu einer Anwendung in einem Fahrzeug vorgesehen ist, ist in einem Batteriegehäuse angeordnet, an dem eine Vorrichtung zu einer Verringerung eines Innendrucks angeordnet ist, die sich nach einer Verringerung des Innendrucks selbsttätig verschließt, wobei die Vorrichtung zur Verringerung des Innendrucks als blattfederbelastetes Ventil ausgeführt ist. Da sich Einzelzellen von Batterien, z. B. Lithium-Ionen-Batteriezellen, bei einem zu hohen Lade- und/oder Entladestrom, insbesondere aber bei einem Kurzschluss, sehr stark erwärmen, baut sich im Inneren der Einzelzellen ein sehr hoher Innendruck auf, der zu einer Zerstörung der Einzelzellen führen kann. Mittels der Erfindung ist es in vorteilhafter Weise möglich, Ausgasungen der Einzelzellen in das Batteriegehäuse zu leiten und den Innendruck in dem Batteriegehäuse kontrolliert zu verringern.The battery according to the invention, which in particular is intended for use in a vehicle is in one Battery housing disposed on which a device to a reduction of an internal pressure is arranged, which after a Automatically closes the internal pressure reduction, wherein the device for reducing the internal pressure as leaf spring loaded Valve is executed. Because single cells of batteries, z. B. lithium-ion battery cells, at a high charge and / or Discharge current, but especially in the case of a short circuit, very strong warm up, builds up inside the individual cells very much high internal pressure, which lead to the destruction of the individual cells can. By means of the invention, it is possible in an advantageous manner Outgassing of the single cells in the battery case too and control the internal pressure in the battery case to reduce.
Das blattfederbelastete Ventil ist aus einer in einem Gehäuse auf einer Dichtung angeordneten Blattfeder gebildet, wobei das Gehäuse zu einem Schutz der Blattfeder mit einer Schutzumrandung ausgeführt ist. Weiterhin ist das Gehäuse zu einer Aufnahme der Dichtung mit einer zu der Dichtung korrespondierenden Aussparung ausgeführt. Diese Konstruktion ist einfach und kostengünstig realisierbar und die Ausgestaltung des Gehäuses bietet einen umfassenden Schutz der Blattfeder vor Beschädigungen.The leaf-spring-loaded valve is made of one in a housing formed on a seal arranged leaf spring, wherein the housing designed to protect the leaf spring with a protective border is. Furthermore, the housing is a receptacle of the seal executed with a corresponding recess to the seal. This construction is simple and inexpensive to implement and the design of the housing provides a comprehensive Protecting the leaf spring from damage.
In einer geschlossenen Stellung übt die Blattfeder einen Druck auf die Dichtung aus, so dass in einem Normalbetrieb der Batterie ein Eindringen von Partikeln und Feuchtigkeit verhindert wird. Somit werden weiterhin eine Bildung von Kondenswasser und eine daraus resultierende Korrosion metallischer Bauteile sowie Kurzschlüsse von Einzelzellen der Batterie vermieden.In In a closed position, the leaf spring exerts a pressure on the gasket, so that in normal operation of the battery Ingress of particles and moisture is prevented. Thus be continues a formation of condensation and a resulting Corrosion of metallic components as well as short circuits of Single cells of the battery avoided.
Bei einem Erreichen eines Schwellwerts des Innendrucks öffnet die Blattfeder, wodurch der Innendruck verringert wird und eine explosionsartige Zerstörung der Batterie und somit Schädigungen eines Umfelds der Batterie vermieden werden. Nach dem Abbau des Innendrucks schließt die Blattfeder selbsttätig, wodurch ein Austritt einer Elektrolytflüssigkeit der Einzelzellen aus dem Batteriegehäuse verhindert wird, was zu einer Erhöhung der Sicherheit für Personen und zu einem Schutz des Umfelds der Batterie führt. Weiterhin wird eine Brandgefahr einer organischen Elektrolytflüssigkeit vermindert, da ein Eindringen von Luftsauerstoff in das Batteriegehäuse durch das selbsttätige Verschließen der Blattfeder vermieden wird.at reaching a threshold value of the internal pressure opens the leaf spring, which reduces the internal pressure and a explosive destruction of the battery and thus damage an environment of the battery can be avoided. After the dismantling of Internal pressure closes the leaf spring automatically, whereby a leakage of an electrolyte liquid of the individual cells is prevented from the battery case, resulting in an increase safety for people and protection of the environment the battery leads. Furthermore, a fire hazard reduced organic electrolyte fluid, since an intrusion of atmospheric oxygen in the battery case by the automatic Closing the leaf spring is avoided.
Alternativ kann die Batterie derart ausgebildet sein, dass ein Gehäusemittelteil des Batteriegehäuses als Vorrichtung zur Verringerung des Innendrucks ausgeführt ist. Dabei ist das Gehäusemittelteil bei einem Erreichen eines Schwellwerts des Innendrucks des Batteriegehäuses derart verformbar, dass an zumindest einer Verbindungsstelle mit weiteren Gehäuseteilen eine oder mehrere Öffnungen zu einer Verringerung des Innendrucks erzeugbar sind. Nach dem Abbau des Innendrucks nimmt das Gehäusemittelteil seine Ausgangsform ein und die Öffnungen sind geschlossen. Dazu ist das Gehäuse aus einem Material gefertigt, welches elastisch verformbar ist. Diese Konstruktion führt zu den gleichen Vorteilen, wie die Verwendung des blattfederbelasteten Ventils und ist ebenfalls einfach und kostengünstig realisierbar.Alternatively, the battery may be formed such that a housing middle part of the battery case is designed as a device for reducing the internal pressure. In this case, when reaching a threshold value of the internal pressure of the battery housing, the housing middle part is deformable such that one or more openings for reducing the internal pressure can be generated at at least one connection point with further housing parts. After the degradation of the internal pressure, the housing takes with telteil its initial shape and the openings are closed. For this purpose, the housing is made of a material which is elastically deformable. This construction leads to the same advantages as the use of the leaf spring-loaded valve and is also easy and inexpensive to implement.
Ferner ist die Batterie aus Einzelzellen herstellbar, wobei die Einzelzellen mit einer Vorrichtung zu einer Verringerung eines Zellinnendrucks, insbesondere in Form einer Berstscheibe, ausgeführt und mittels einer Kühlvorrichtung kühlbar sind. Somit kann eine durch die Einzelzellen erzeugte Wärme, die zu einer oberhalb einer die Lebensdauer der Batterie verkürzenden Temperatur führen kann, abgeführt werden. Mittels der Vorrichtung zu dem Druckabbau wird eine explosionsartige Zerstörung der Einzelzellen der Batterie vermieden.Further the battery can be manufactured from single cells, whereby the single cells with a device for reducing intracellular pressure, in particular in the form of a rupture disk, executed and by means of a cooling device can be cooled. Thus, can a heat generated by the individual cells, which leads to a above a shortening the life of the battery Temperature can be dissipated. through the device for the pressure reduction is an explosive destruction of the Single cells of the battery avoided.
