Abstract
Description
Die vorliegende Erfindung bezieht sich auf einen Akkumulator mit Beschädigungsschutz und ein Verfahren zum Erkennen von Beschädigungen an einem Akkumulator.The present invention relates to an accumulator with damage protection and a method for detecting damage to an accumulator.
Stand der TechnikState of the art
Wiederaufladbare Akkumulatoren werden beispielsweise in Elektrofahrzeugen oder tragbaren Elektrogeräten als Energiespeicher genutzt. Akkumulatoren beinhalten dabei häufig Chemikalien und andere Substanzen, die potentiell gefährlich für Personen und Umwelt sein können. Daher werden Akkumulatoren üblicherweise in Gehäusen für Unbefugte unzugänglich verschlossen.Rechargeable batteries are used for example in electric vehicles or portable electrical appliances as energy storage. Accumulators often contain chemicals and other substances that can potentially be dangerous to people and the environment. Therefore, accumulators are usually closed in enclosures inaccessible to unauthorized persons.
Bei Unfällen, mechanischen Belastungen oder anderen widrigen Umwelteinflüssen wie Hitze oder Spannungsüberlastung können Akkumulatoren und dabei insbesondere Akkumulatorzellen beschädigt werden. Außerdem ist es möglich, dass Unbefugte Manipulationen an dem Akkumulator vornehmen können, beispielsweise um wertvolle Substanzen aus dem Akkumulator zu entnehmen oder andere Manipulationen an den Akkumulatorzellen vorzunehmen. Durch derartige Eingriffe kann die Sicherheit für Personen und Umwelt gefährdet werden, wenn der Akkumulator sich nicht mehr in einem gewöhnlichen Betriebszustand befindet.In the case of accidents, mechanical loads or other adverse environmental influences such as heat or voltage overload, accumulators and in particular accumulator cells can be damaged. In addition, it is possible that unauthorized persons can perform manipulations on the accumulator, for example in order to remove valuable substances from the accumulator or to perform other manipulations on the accumulator cells. Such interventions can endanger personal safety and the environment if the accumulator is no longer in an ordinary operating condition.
Es besteht daher ein Bedarf nach Akkumulatoren mit Schutz vor Beschädigungen und Manipulationen von außen.There is therefore a need for accumulators with protection against damage and manipulation from the outside.
Zusammenfassung der ErfindungSummary of the invention
Eine Idee der vorliegenden Erfindung ist es, einen Akkumulator gegen unbeabsichtigte Beschädigungen beispielsweise bei Unfällen oder unbefugte Manipulationen von außen abzusichern. Dazu können bei erkannten Beschädigungen bereits im Akkumulator selbst automatisch geeignete Gegenmaßnahmen eingeleitet werden, um Gefährdungen von Personen oder der Umwelt zu vermeiden.One idea of the present invention is to protect an accumulator against unintentional damage, for example in the case of accidents or unauthorized manipulations from the outside. For this purpose, if damage is detected, suitable countermeasures can automatically be initiated in the accumulator itself in order to avoid endangering persons or the environment.
Eine Ausführungsform der vorliegenden Erfindung besteht daher in einem Akkumulator nach Anspruch 1 mit mindestens einer Akkumulatorzelle, mindestens einem Manipulationssensor, welcher dazu ausgelegt ist, anormale Betriebsparameter des Akkumulators zu erfassen, einem Reservoir, welches Substanzen zum Unterbinden unerwünschter chemischer Reaktionen in dem Akkumulator beinhaltet, und einer Steuereinrichtung, welche dazu ausgelegt ist, in Abhängigkeit von einem Ausgabesignal des mindestens einen Manipulationssensors die Freisetzung der Substanzen in dem Reservoir zu veranlassen.An embodiment of the present invention is therefore in an accumulator according to claim 1 having at least one accumulator cell, at least one manipulation sensor which is adapted to detect abnormal operating parameters of the accumulator, a reservoir, which contains substances for preventing unwanted chemical reactions in the accumulator, and a control device which is designed to cause the release of the substances in the reservoir in dependence on an output signal of the at least one manipulation sensor.
Vorzugsweise können die Substanzen chemische Bindemittel zur Neutralisation aus der Akkumulatorzelle austretender Chemikalien umfassen. Dadurch können gefährliche Stoffe, welche möglicherweise aus den Akkumulatorzellen austreten können, zur Vermeidung von Gefahren für Umwelt, Natur und Personen effektiv und schnell bereits im Akkumulator bekämpft werden.Preferably, the substances may comprise chemical binders for neutralization of chemicals emerging from the accumulator cell. As a result, dangerous substances that may possibly escape from the accumulator cells can be effectively and quickly combated already in the accumulator to avoid risks to the environment, nature and people.
Vorteilhafterweise können die anormalen Betriebsparameter ein Öffnen eines Gehäuses des Akkumulators, ein Austreten von Chemikalien aus der Akkumulatorzelle, ein Ansteigen der Temperatur in dem Akkumulator, ein Ansteigen des Drucks in dem Akkumulator und/oder eine Beschädigung des Gehäuses des Akkumulators umfassen. Durch das Vorsehen entsprechender Manipulationssensor können damit alle potentiell gefährlichen, nicht vorgesehenen Betriebszustände des Akkumulators erkannt werden und geeignete Gegenmaßnahmen eingeleitet werden.Advantageously, the abnormal operating parameters may include opening a housing of the accumulator, leaking chemicals from the accumulator cell, increasing the temperature in the accumulator, increasing the pressure in the accumulator, and / or damaging the housing of the accumulator. By providing appropriate manipulation sensor can thus all potentially dangerous, unscheduled operating conditions of the accumulator are detected and appropriate countermeasures are initiated.
Es kann vorgesehen sein, dass das Reservoir Ventile umfasst, und dass die Steuereinrichtung dazu ausgelegt ist, die Freisetzung der Substanzen in dem Reservoir durch Öffnen der Ventile zu veranlassen. Alternativ kann das Reservoir Sprengkapseln umfasst, und die Steuereinrichtung kann dazu ausgelegt ist, die Freisetzung der Substanzen in dem Reservoir durch Zünden der Sprengkapseln zu veranlassen. In beiden Fällen ist ein schnelles und zuverlässiges Freisetzen der Substanzen zur Vermeidung von Gefahren bei einer Beschädigung von Akkumulatorzellen gewährleistet.It can be provided that the reservoir comprises valves, and that the control device is designed to cause the release of the substances in the reservoir by opening the valves. Alternatively, the reservoir may comprise blasting caps, and the control means may be arranged to cause the release of the substances in the reservoir by detonating the blasting capsules. In both cases, a rapid and reliable release of the substances to prevent dangers in case of damage to battery cells is guaranteed.
Gemäß einer Ausführungsform der vorliegenden Erfindung wird ein Verfahren zum Erkennen von Beschädigungen an einem Akkumulator nach Anspruch 6 geschaffen, mit den Schritten des Erfassens von anormalen Betriebsparametern des Akkumulators über mindestens einen Manipulationssensor, des Ausgebens eines Ausgabesignals, welches das Auftreten anormaler Betriebsparameter des Akkumulators anzeigt, an eine Steuereinrichtung in dem Akkumulator, und des Erzeugens eines Steuersignals durch die Steuereinrichtung zum Freisetzen von Substanzen zum Unterbinden unerwünschter chemischer Reaktionen in dem Akkumulator aus einem Reservoir in dem Akkumulator.According to one embodiment of the present invention, there is provided a method of detecting damage to an accumulator as claimed in claim 6 comprising the steps of detecting abnormal operating parameters of the accumulator via at least one manipulation sensor, outputting an output signal indicative of the occurrence of abnormal operating parameters of the accumulator, to a controller in the accumulator, and generating a control signal by the controller for releasing substances to prevent unwanted chemical reactions in the accumulator from a reservoir in the accumulator.
Weitere Modifikationen und Variationen ergeben sich aus den Merkmalen der abhängigen Ansprüche.Further modifications and variations will be apparent from the features of the dependent claims.

Ausführliche Beschreibung der ErfindungDetailed description of the invention
Akkumulatoren im Sinne der vorliegenden Erfindung umfassen alle gängigen elektrischen Energievorhaltesysteme aus Sekundärzellen, insbesondere beispielsweise Lithium-Ionen-Akkumulatoren, Lithium-Titanat-Akkumulatoren, Lithium-Polymer-Akkumulatoren, Lithium-Metall-Akkumulatoren, Lithium-Schwefel-Akkumulatoren, Natrium-Nickelchlorid-Akkumulatoren, Natrium-Schwefel-Akkumulatoren, Nickel-Metallhydrid-Akkumulatoren und ähnliche Akkumulatoren. Dabei können die Akkumulatoren insbesondere als Traktionsbatterien für Elektro- oder Elektro-Hybridfahrzeuge und als Energiespeicher für tragbare Elektrogeräte verwendet werden. Akkumulatoren im Sinne der vorliegenden Erfindung können ein oder mehrere Akkumulatorzellen beinhalten.Accumulators for the purposes of the present invention include all current electrical energy retention systems from secondary cells, in particular, for example, lithium-ion accumulators, lithium titanate accumulators, lithium polymer accumulators, lithium metal accumulators, lithium sulfur accumulators, sodium nickel chloride Accumulators, Sodium-Sulfur Accumulators, Nickel-Metal Hydride Accumulators and similar Accumulators. The accumulators can be used in particular as traction batteries for electric or electric hybrid vehicles and as energy storage for portable electrical appliances. Accumulators according to the present invention may include one or more accumulator cells.
Im Folgenden können Manipulationssensoren im Sinne dieser Beschreibung alle Erfassungseinrichtungen umfassen, welche physikalische Eingriffe an dem überwachten Akkumulator erkennen und entsprechende Anzeigesignale an die zugeordneten Rechen- oder Steuereinrichtungen übermitteln können. Beispielsweise können derartige Erfassungseinrichtungen über Licht, Ionenstrahlen, Temperatur, Druck, elektrischen Widerstand, elektrische Spannung oder ähnliche physikalische Effekte Änderungen des Normzustandes erkennen, welche mit einem Tamper-Eingriff bzw. einer Manipulation des überwachten Akkumulators einhergehen. Manipulationssensoren im Sinne dieser Beschreibung können daher beispielsweise Schalter, Tamperfolien (z. B. ein sogenanntes „Wire Mesh” bzw. eine Sicherheitsleitgitterfolie), Lichtschranken, kapazitive Anordnungen, lichtempfindliche Sensorflächen oder ähnliche Einrichtungen umfassen. Es sollte klar sein, dass auch weitere Erfassungseinrichtungen mit ähnlicher Funktionalität Manipulationssensoren im Sinne dieser Beschreibung darstellen können.In the following, manipulation sensors in the sense of this description can include all detection devices which can detect physical interventions on the monitored accumulator and transmit corresponding display signals to the associated computing or control devices. For example, such detection devices can detect changes in the standard state via light, ion beams, temperature, pressure, electrical resistance, electrical voltage or similar physical effects, which are accompanied by a tamper intervention or a manipulation of the monitored accumulator. Manipulation sensors in the sense of this description can therefore comprise, for example, switches, tamper foils (eg a so-called "wire mesh" or a safety grating foil), light barriers, capacitive arrangements, photosensitive sensor surfaces or similar devices. It should be clear that other detection devices with similar functionality can also represent manipulation sensors in the sense of this description.
