Description
Die Erfindung betrifft eine Traktionsbatterie für elektrisch betriebene Kraftfahrzeuge, die aus einer Vielzahl elektrisch zusammengeschalteter Einzelzellen besteht, gemäß dem Oberbe griff des 1. Patentanspruches.The invention relates to a traction battery for electric powered motor vehicles made from a variety of electrical interconnected single cells, according to the Oberbe handle of the 1st claim.
Aus Gründen des Umweltschutzes, vor allem um eine bessere Rein haltung der Luft zu gewährleisten, stellt sich heute immer mehr das Problem, die Schadstoffemission von Kraftfahrzeugen im Stra ßenverkehr zu verringern. Neben technischen Verbesserungen an den mit Verbrennungsmotoren ausgerüsteten Kraftfahrzeugen rückt auch immer mehr das Elektroauto in den Blickpunkt des Interes ses, um verkehrsbedingte Umweltprobleme zu lösen. Für das Elek troauto spricht, daß die Schadstoffemissionen fernab von ver kehrlichen Ballungsräumen entstehen. Wegen einer vorläufig be grenzten Reichweite des Elektroautos ist dabei vor allem an einen Einsatz im Verkehrsballungszentren gedacht, wo die Bela stung der Luft mit Kohlenmonoxid, Stickstoffoxiden, Kohlenwas serstoffen und Ruß in Verbindung mit klimatischen und photo technischen Prozessen besonders leicht zu Smogbildung und Ozon bildung führt.For reasons of environmental protection, especially for a better clean It is becoming increasingly important to ensure that the air is kept the problem of pollutant emissions from motor vehicles in the street reduce external traffic. In addition to technical improvements the motor vehicles equipped with internal combustion engines also the electric car is increasingly in the focus of interest to solve traffic-related environmental problems. For the elec troauto says that pollutant emissions far from ver congested urban areas. Because of a provisionally be limited range of the electric car is above all intended for use in traffic conurbations where the Bela Air pollution with carbon monoxide, nitrogen oxides, coal water substances and soot in connection with climatic and photo technical processes particularly easy to smog and ozone education leads.
Bei derart elektrisch betriebenen Kraftfahrzeugen ist nun ein Sachverhalt besonders zu beachten; bei der normalerweise Klein- und extremen Leichtbauweise des Fahrzeuges ist das Verhältnis des Batterie-Gewichtes zu dem Fahrzeug-Leergewicht - ohne Bat terie - unter Sicherheits- und Unfall-Gesichtspunkten sehr kri tisch anzusehen. Bei einem Umfallgeschehen kann die sehr schwe re und kompakte Traktionsbatterie ein kontrolliertes Knautschen der dem Fahrgastraum vorgelagerten, nachgiebigen Knautschzone der Fahrzeugkarosserie beeinträchtigen und/oder die Traktions batterie kann sogar in unkontrollierter Weise in das Innere der Sicherheitszone des Fahrgastraumes eindringen. Gleichzeitig können die Gehäuse der Einzelzellen beschädigt werden und der gefährliche Inhalt der Einzelzellen kann auslaufen. Dies gilt vor allem für Natrium-Schwefel- oder Natrium-Nickelchlorid-Bat terien, die für einen Einsatz in Elektroautos als Hochleistungs batterien vorgesehen sind.In such electrically operated motor vehicles there is now a Pay particular attention to the facts; where usually small and extreme lightweight construction of the vehicle is the ratio the battery weight to the vehicle curb weight - without bat terie - very critical from a safety and accident point of view to look at the table. In the event of an accident, it can be very difficult right and compact traction battery a controlled crunch the flexible crumple zone in front of the passenger compartment affect the vehicle body and / or the traction The battery can even enter the inside of the battery in an uncontrolled manner Enter the safety zone of the passenger compartment. At the same time can damage the housing of the individual cells and the dangerous contents of the single cells can leak. this applies especially for sodium-sulfur or sodium-nickel chloride bat series that are for use in electric cars as high performance batteries are provided.
So besteht ein Batteriesystem aus Natrium-/Nickelchlorid aus ungefähr 300 einzelnen Zellen, die in ihrer Form quadratisch bzw. rechteckig aufgebaut sind und im Verbund in dem Batterie gehäuse orthogonal nebeneinander angeordnet sind. Bei einem Unfallgeschehen kommt es durch die auftretenden Kräfte und Be lastungen zu einer Blockbildung des Batteriegehäuses mit den vorher angegebenen Folgen.A battery system consists of sodium / nickel chloride about 300 individual cells that are square in shape or are constructed rectangular and in the composite in the battery housing are arranged orthogonally next to each other. At a Accidents occur due to the forces and loads that occur loads to block the battery housing with the previously specified episodes.
Aus dem Stande der Technik sind Batterien mit einer derartigen orthogonal gerasteten Anordnung der Einzelzellen bekannt z. B. aus der DE-PS 39 07 697, der GB-PS 1 386 525 und aus der Ver öffentlichung "Highperformance batteries for off-peak energy storage and electric-vehicle propulsion" (Progress Report for the period Jan.-June 1974) Seite 108.Batteries with such a battery are known from the prior art orthogonally locked arrangement of the individual cells known z. B. from DE-PS 39 07 697, GB-PS 1 386 525 and from Ver publication "High performance batteries for off-peak energy storage and electric vehicle propulsion "(Progress Report for the period Jan.-June 1974) page 108.
Der Erfindung liegt die Aufgabe zugrunde, eine Traktionsbatte rie für elektrisch betriebene Kraftfahrzeuge, bestehend aus einer Vielzahl von elektrisch zusammengeschalteten Einzelzellen zu schaffen, bei der die vorher geschilderten Nachteile bei einem Unfallgeschehen nicht mehr auftreten.The invention has for its object a traction battery for electric motor vehicles, consisting of a variety of electrically interconnected individual cells to create, in which the disadvantages described above no longer occur in an accident.
Die gestellte Aufgabe wird erfindungsgemäß mit einer Trakti onsbatterie mit den kennzeichnenden Merkmalen des 1. Patent anspruches gelöst.The task is accomplished according to the invention with a tract onsbatterie with the characteristic features of the 1st patent claim solved.
Erfindungsgemäß sind die Einzelgehäuse der Einzelzellen so sta bil ausgebildet, daß sie die bei einem Unfallgeschehen auftre tenden Kräfte und Belastungen berstfrei überstehen. Die Einzel zellen selbst sind in dem Batteriegehäuse nach einem vorgege benen hexagonalen Raster ohne eine gegenseitige formschlüssige Fixierung angeordnet. Das Batteriegehäuse, in dem die Einzel zellen angeordnet sind, ist mit Sollbruchstellen versehen oder in seinen Wandungen insgesamt so schwach ausgebildet, daß es unter den bei einem Unfallgeschehen auftretenden Kräften und Belastungen zerbricht und damit die Einzelzellen aus dem Bat teriegehäuse freigegeben werden. Die quer zur Fahrtrichtung des Kraftfahrzeuges bemessene Breite des Batteriegehäuses ist 10 bis 20% geringer als der Abstand, der für die Unterbringung des Batteriegehäuses zwischen den beiden Längsträgern des Kraft fahrzeuges zur Verfügung steht.According to the individual housings of the individual cells are so sta bil trained that they occur in an accident withstand forces and loads without bursting. The single cells themselves are in the battery case according to a given benen hexagonal grid without a mutual positive Fixation arranged. The battery case in which the single cells are arranged, is provided with predetermined breaking points or in its walls so weak overall that it under the forces occurring in an accident and Loads break and thus the individual cells from the bat series housings are released. The transverse to the direction of travel Motor vehicle dimensioned width of the battery housing is 10 up to 20% less than the distance required for accommodation of the battery housing between the two side members of the force vehicle is available.
In der Praxis hat sich bei Crash-Versuchen herausgestellt, daß der mit dem Erfindungsgegenstand angestrebte Erfolg sehr gut erreicht werden kann, wenn sowohl die Wandungen des Batterie gehäuses als auch die Einzelgehäuse der Einzelzellen aus Alu minium bestehen.In practice, crash tests have shown that the success sought with the subject of the invention was very good can be achieved if both the walls of the battery housing as well as the individual housings of the individual cells made of aluminum minium exist.
Der Erfindungsgegenstand wird nachfolgend anhand einer Zeich nung noch näher erläutert.The subject of the invention is based on a drawing tion explained in more detail.
Die Figur zeigt das fertigungsgemäß im Bugraum des Kraftfahr zeugs angeordnete Batteriegehäuse mit den Einzelzellen in der Draufsicht.The figure shows the production in the bow area of the motor vehicle Battery case arranged with the individual cells in the Top view.
In dieser Figur sind mit 1 und 1′ die-beiden Längsträger und mit 2 der Querträger im Bugraum des Elektroautos bezeichnet. Mit 3 ist das Batteriegehäuse mit abgenommenem Deckel in Drauf sicht dargestellt. In dem Batteriegehäuse sind die kreiszylin drisch ausgebildeten Einzelzellen 4 hexagonal angeordnet. Das Batteriegehäuse besitzt an seinen seitlichen Wänden 5, 5′ ein gearbeitete Sollbruchstellen 6. Zwischen den Seitenwänden des Batteriegehäuses und den beiden Längsträgern befinden sich freie Zwischenräume 7 und 7′.In this figure, 1 and 1 ', the-two longitudinal members and 2 of the cross members in the bow of the electric car. With 3 the battery housing with the cover removed is shown in a top view. In the battery case, the single cells 4 are arranged in a circular hexagon. The battery housing has on its side walls 5 , 5 'a worked predetermined breaking points 6th Between the side walls of the battery housing and the two side members are free spaces 7 and 7 '.
Im Fall eines Unfallgeschehens, z. B. bei einem Frontal-Crash, schiebt sich der Querträger 2 gegen die gegenüberliegende Wand 8 des Batteriegehäuses und das Batteriegehäuse 3 wird in dem Sinne verformt, daß die Wände 5, 5′ des Batteriegehäuses in Richtung gegen die beiden Längsträger herausgedrückt werden. Gleichzeitig bersten die Seitenwände des Batteriegehäuses an den eingearbeiteten Sollbruchstellen. Die in dem Batteriege häuse nicht fixierten Einzelzellen werden dann nicht mehr in nerhalb des Batterieverbundes gehalten. Die Einzelzellen sind frei gegeneinander verschiebbar und können durch an den Soll bruchstellen entstandene Lücken in den Seitenwänden 5, 5′ des Batteriegehäuses aus dem Batterieverbund austreten und in die (zuvor) freien Zwischenräume 7 und 7′ gelangen. Die Einzelge häuse der Einzelzellen 4 sind so stabil ausgebildet, daß eine gewisse Verformung der Einzelzellen durch die beim Unfall-Crash auftretenden Druckkräfte auftreten kann. Eine Beschädigung der Einzelgehäuse der Einzelzellen und damit verbunden ein Auslau fen der Batterieflüssigkeit tritt normalerweise nicht ein. In the event of an accident, e.g. B. in a frontal crash, the cross member 2 pushes against the opposite wall 8 of the battery housing and the battery housing 3 is deformed in the sense that the walls 5 , 5 'of the battery housing are pressed out in the direction against the two side members. At the same time, the side walls of the battery housing burst at the incorporated predetermined breaking points. The individual cells that are not fixed in the battery housing are then no longer held within the battery system. The individual cells are freely displaceable against each other and can emerge from the battery pack through the gaps in the side walls 5 , 5 'of the battery housing and enter the (previously) free spaces 7 and 7 '. The individual housing of the individual cells 4 are so stable that a certain deformation of the individual cells can occur due to the pressure forces occurring in the accident crash. Damage to the individual housing of the individual cells and the associated leakage of the battery fluid do not normally occur.
Die Vorteile des Erfindungsgegenstandes bestehen insbesondere darin, daß bei elektrisch betriebenen Kraftfahrzeugen bei einem Unfallgeschehen die von der Batterie ausgehenden Gefahren für die Wageninsassen weitgehend verringert werden. Dies ergibt sich einmal dadurch, daß die Einzelzellen eine große Auslauf- und Berstsicherheit besitzen. Infolge der hexagonalen Anordnung der Einzelzellen in dem Batteriegehäuse, wodurch eine große Verformbarkeit bei einem Unfallgeschehen eintritt, kommt es zu einem crashbedingten Auflösen des ursprünglichen Batteriekör pers der damit nicht in die Insassenzelle des Kraftfahrzeuges eindringen kann. Außerdem tritt nur eine geringe, massebedingte Sekundärwirkung der Traktionsbatterie im Crash-Falle ein, da sich immer nur die Einzelmasse einer Einzelzelle entfalten kann.The advantages of the subject matter of the invention exist in particular in that in the case of electrically operated motor vehicles in one Accidents happen the dangers for the battery the car occupants are largely reduced. This results in the fact that the individual cells have a large and have burst protection. Due to the hexagonal arrangement of the single cells in the battery case, creating a large one Deformability occurs in the event of an accident a crash-related dissolution of the original battery body pers so not in the occupant cell of the motor vehicle can penetrate. In addition, only a small, mass-related occurs Secondary effect of the traction battery in the event of a crash unfold only the individual mass of a single cell can.
