Description
Die Erfindung betrifft einen Akkupack der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The invention relates to a battery pack of the type specified in the preamble of
Für die Stromversorgung von elektrischen Verbrauchern kommen verbreitet elektrische Akkupacks zur Anwendung, bei denen es für eine raum- und gewichtssparende Bauweise u. a. auf eine hohe Energiedichte ankommt. Bei derartigen Anwendungsfällen finden Akkupacks zunehmend Verwendung, die eine bestimmte Anzahl von elektrisch zusammengeschalteten Flachzellen umfassen.For the power supply of electrical consumers are widely used electric battery packs, in which it is a space and weight-saving design u. a. depends on a high energy density. In such applications, battery packs are increasingly used, which include a certain number of electrically interconnected flat cells.
Derartige Akkupacks werden u. a. zur Notstromversorgung bei Ausfall der eigentlichen Stromversorgung vorgesehen, wobei in einem solchen Fall die Funktionssicherheit des Akkupacks gegeben sein muss.Such battery packs are u. a. provided for emergency power supply in case of failure of the actual power supply, in which case the reliability of the battery pack must be given.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Akkupack der eingangs genannten Gattung zu schaffen, dessen Funktionssicherheit wesentlich verbessert ist.The present invention has for its object to provide a battery pack of the type mentioned, whose reliability is significantly improved.
Diese Aufgabe wird durch einen Akkupack mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a battery pack with the features of
Die gasführenden Halteleisten im Gehäuse sorgen dafür, dass das temperierte Gas möglichst gut im Innenraum des Gehäuses verteilt und unmittelbar den Zwischenräumen zwischen den Flachzellen zugeführt wird.The gas-conducting retaining strips in the housing ensure that the tempered gas is distributed as well as possible in the interior of the housing and is supplied directly to the intermediate spaces between the flat cells.
Mittels einer vorzugsweise vorgesehenen Heizung, die aus Platzgründen vor dem Zulauf für die Einleitung des Gases liegt, kann das strömende Gas bedarfsweise erwärmt werden, um so die Flachzellen auf eine Temperatur zu erwärmen, bei der die Flachzellen die optimale elektrische Leistung abgeben. Gemäß einer bevorzugten Ausgestaltung ist vorgesehen, dass die Vorrichtung zur Erzeugung der Gasströmung ein regelbares Gebläse ist, so dass der Luftdurchsatz auf einen optimalen Wert einstellbar ist. Bei ungünstigen Umgebungsbedingungen und/oder bei nicht hermetisch dicht geschlossenen Systemen ist es vorteilhaft, eine Trocknungseinrichtung für das Gas vorzusehen. Eine solche Trocknungseinrichtung kann beispielsweise durch ein Volumen eines hygroskopischen Salzes gebildet sein. Alternativ hierzu kann die Trocknungseinrichtung einen Reaktor umfassen, welcher ein Sorptionsmaterial wie beispielsweise Zeolith oder Selikagel enthält.By means of a preferably provided heating, which is located for reasons of space in front of the inlet for the introduction of the gas, the flowing gas can be heated as needed, so as to heat the flat cells to a temperature at which the flat cells emit the optimum electrical power. According to a preferred embodiment, it is provided that the device for generating the gas flow is a controllable fan, so that the air flow rate can be set to an optimum value. In unfavorable environmental conditions and / or in non-hermetically sealed systems, it is advantageous to provide a drying device for the gas. Such a drying device can be formed, for example, by a volume of a hygroscopic salt. Alternatively, the drying device may comprise a reactor containing a sorbent material such as zeolite or selogagel.
Es ist zweckmäßig, dass die Halteleisten an Wänden des Gehäuses formschlüssig befestigt sind, und dass die Halteleisten mit Öffnungen versehen sind, durch die der das Gas führende Kanal mit dem Innenraum verbunden ist. Durch die formschlüssige Befestigung der Halteleisten an den Wänden des Gehäuses werden zusätzliche Befestigungsmittel vermieden. Durch die Öffnungen in den Halteleisten kann eine Vielzahl von Durchtritten für das Gas durch die Halteleisten vorgesehen werden, so dass durch diese Maßnahme die Luftverteilung weiter beeinflusst werden kann. Die Halteleisten weisen zweckmäßigerweise ein offenes und ein geschlossenes Ende auf, wobei die offenen Enden der Halteleisten an einen Anschlusskasten angeschlossen sind. Der Anschlusskasten wirkt dabei als Verteiler der Gasströmung auf die mehreren Halteleisten. Vorzugsweise ist an einem Anschlusskasten der Zulauf und an dem anderen Anschlusskasten der Ablauf angeordnet.It is expedient that the retaining strips are fastened to walls of the housing in a form-fitting manner, and that the retaining strips are provided with openings through which the gas-carrying channel is connected to the interior. The positive fastening of the retaining strips on the walls of the housing additional fastening means are avoided. Through the openings in the retaining strips, a plurality of passages for the gas can be provided by the retaining strips, so that by this measure, the air distribution can be further influenced. The retaining strips expediently have an open and a closed end, wherein the open ends of the retaining strips are connected to a terminal box. The junction box acts as a distributor of gas flow on the multiple retaining strips. Preferably, the inlet is arranged on a connection box and the outlet is arranged on the other connection box.
Gemäß einer zweckmäßigen Ausgestaltung ist zwischen dem Ablauf und dem Zulauf eine Leitung zur Bildung eines geschlossenen Gassystems vorgesehen, und in dieser Leitung sind das Gebläse, die Heizung und ggf. die Trocknungseinrichtung angeordnet. In weiterer Ausgestaltung der Halteleisten bestehen diese aus zwei halbzylindrischen Leistenteilen, die den gasfürenden Kanal bilden. An den Leistenteilen sind zur Flachzelle gerichtete Schenkel vorgesehen, zwischen denen ein Spalt zur Aufnahme einer seitlichen Siegelnaht der Flachzelle gebildet ist. Auf diese Weise kann beim Zusammenbau der Leistenteile die seitliche Siegelnaht zwischen den Schenkeln eingespannt werden, so dass ein guter mechanischer Halt gewährleistet ist. Zur weiteren Erhöhung der mechanischen Festigkeit der Flachzelle im Gehäuse ist es zweckmäßig, dass an den Schenkeln Verbindungsabschnitte angeformt sind, die die Flachzelle an den seitlichen Rändern umgreifen. Als vorteilhaft wird weiterhin angesehen, dass die Schenkel mit der Siegelnaht und die Verbindungsabschnitte mit der Flachzelle verklebt sind.According to an expedient embodiment, a line for forming a closed gas system is provided between the outlet and the inlet, and in this line the fan, the heater and possibly the drying device are arranged. In a further embodiment of the retaining strips, these consist of two semi-cylindrical strip parts, which form the gassenderenden channel. On the strip parts directed to the flat cell legs are provided, between which a gap for receiving a lateral sealing seam of the flat cell is formed. In this way, the lateral sealing seam between the legs can be clamped during assembly of the strip parts, so that a good mechanical support is ensured. To further increase the mechanical strength of the flat cell in the housing, it is expedient that connecting portions are formed on the legs, which engage around the flat cell at the lateral edges. It is further considered to be advantageous that the legs are glued to the sealed seam and the connecting sections are glued to the flat cell.
In besonderer Ausgestaltung zur Befestigung der Halteleisten im Gehäuse wird vorgeschlagen, dass an der Innenseite von Wänden des Gehäuses kreisabschnittförmige Aufnahmenuten ausgebildet sind, in die die Halteleisten eingeschoben sind. Die Öffnungen in den Halteleisten sind zweckmäßigerweise in Abständen zwischen den Verbindungsabschnitten angeordnet. Um eine Temperaturschichtung bezogen auf die Höhe der im Gehäuse stehend angeordneten Flachzellen zu vermeiden, ist es zweckmäßig, dass die Öffnungen bezogen auf eine Durchströmung im Innenraum derart angeordnet sind, dass sich auch eine vertikale Komponente der Strömungsrichtung ergibt. Dies kann dadurch erreicht werden, dass die Öffnungen an der Halteleiste, an der das Gas in den Innenraum einströmt, auf einer anderen Höhe angeordnet sind als die Öffnungen an der Halteleiste, an der das Gas abgeführt wird.In a particular embodiment for fastening the retaining strips in the housing is proposed that on the inside of walls of the housing circular section-shaped receiving grooves are formed, into which the retaining strips are inserted. The openings in the retaining strips are expediently arranged at intervals between the connecting sections. In order to avoid a temperature stratification with respect to the height of the flat cells arranged in the housing, it is expedient for the openings to be arranged in the interior in relation to a throughflow in such a way that a vertical component of the flow direction also results. This can be achieved in that the openings on the retaining strip, at which the gas flows into the interior, are arranged at a different height than the openings on the retaining strip, at which the gas is discharged.
