Weiterhin kann die Verspannungseinrichtung die Zugkraft länger und besser aufrechterhalten.If the bracing device is formed at least partially resilient, this has the advantage that further components and / or work steps can be dispensed with. Furthermore, the tensioning device can maintain the tensile force longer and better.
Wird die Verspannungseinrichtung als Verbänderung, umfassend einen ersten Endabschnitt und einen zweiten Endabschnitt ausgebildet, wobei der erste Endabschnitt und der zweite Endabschnitt derart miteinander verbunden, zum Beispiel verhakt, verklammert, verklebt, verpresst, verriegelt oder verschweißt, werden, dass die Zugkraft aufrechterhalten werden kann, hat dies den Vorteil, dass die Herstellung und Anbringung der Verspannungseinrichtung vereinfacht werden kann. Dadurch kann die Verspannungseinrichtung aus einem Endlosmaterial bedarfsgerecht konfektioniert werden.If the bracing device is designed as a braid, comprising a first end section and a second end section, wherein the first end section and the second end section are interconnected, for example hooked, clamped, glued, pressed, locked or welded, the pulling force can be maintained , This has the advantage that the manufacture and attachment of the bracing device can be simplified. As a result, the tensioning device can be made up of a continuous material as required.
Umschließen die erste Kraftumlenkeinrichtung und die zweite Kraftumlenkeinrichtung die Batteriezellen derart, dass die Batteriezellen gegeneinander verspannt werden, hat dies den Vorteil, dass eine periodische Volumenänderung der Batteriezellen beim Laden / Entladen, die die Lebensdauer der Batteriezellen verkürzt, vermindert oder verhindert werden kann. Außerdem kann ein „Quellen“ der Batteriezellen über ihre Lebenszeit, also ein fortlaufende Volumenvergrößerung der Batteriezellen über ihre Lebenszeit vermindert oder verhindert werden.The first Kraftumlenkeinrichtung and the second Kraftumlenkeinrichtung include the battery cells such that the battery cells are braced against each other, this has the advantage that a periodic volume change of the battery cells during charging / discharging, which shortens the life of the battery cells can be reduced or prevented. In addition, a "swelling" of the battery cells over their lifetime, so a continuous increase in volume of the battery cells over their lifetime can be reduced or prevented.
Umschließen die erste Kraftumlenkeinrichtung und die zweite Kraftumlenkeinrichtung, oder eine dritte Kraftumlenkeinrichtung und eine vierte Kraftumlenkeinrichtung, die Batteriezellen derart, dass die Batteriezellen gegen eine Temperiereinrichtung, zum Beispiel Kühleinrichtung wie Kühlplatte oder Heizeinrichtung verspannt werden, hat dies den Vorteil, dass die Temperierung der Batteriezellen verbessert werden kann.Includes the first Kraftumlenkeinrichtung and the second Kraftumlenkeinrichtung, or a third Kraftumlenkeinrichtung and a fourth Kraftumlenkeinrichtung, the battery cells such that the battery cells are braced against a tempering, for example, cooling device such as cooling plate or heater, this has the advantage that the temperature of the battery cells can be improved.
Wird weiterhin ein Batteriegehäuse zum Aufnehmen der Batteriezellen bereitgestellt, hat dies den Vorteil, dass die Batteriezellen bzw. die Umgebung besser geschützt werden können. Dadurch kann die Gefahr der Beschädigung der Batteriezellen reduziert werden. Außerdem kann die Gefahr für die Umgebung im Fehlerfall reduziert werden.Furthermore, if a battery housing is provided for receiving the battery cells, this has the advantage that the battery cells or the environment can be better protected. This can reduce the risk of damaging the battery cells. In addition, the risk to the environment can be reduced in the event of a fault.
Nimmt das Batteriegehäuse die Batteriezellen in einer Übergangspassung auf, hat dies den Vorteil, dass die Übertragung der Druckkraft von der ersten Kraftumlenkeinrichtung und der zweiten Kraftumlenkeinrichtung auf die Batteriezellen verbessert werden kann.If the battery housing accommodates the battery cells in a transitional fit, this has the advantage that the transmission of the pressure force from the first force deflection device and the second force deflection device to the battery cells can be improved.
Wird das Batteriegehäuse zumindest teilweise flexibel ausgebildet, hat dies den Vorteil, dass die Übertragung der Druckkraft von der ersten Kraftumlenkeinrichtung und der zweiten Kraftumlenkeinrichtung auf die Batteriezellen weiter verbessert werden kann.If the battery housing is designed to be at least partially flexible, this has the advantage that the transmission of the pressure force from the first force deflection device and the second force deflection device to the battery cells can be further improved.
Wird das Batteriegehäuse dicht, zum Beispiel flüssigkeitsdicht oder gasdicht, ausgebildet, hat dies den Vorteil, dass das die Schutzwirkung des Gehäuses verbessert werden kann.If the battery housing is tight, for example, liquid-tight or gas-tight, formed, this has the advantage that the protective effect of the housing can be improved.
Umfasst das Batteriegehäuse die erste Kraftumlenkeinrichtung und / oder die zweite Kraftumlenkeinrichtung, hat dies den Vorteil, dass das Fixieren und / oder Verspannen von Batteriezellen weiter vereinfacht werden kann. Dadurch können weitere Bauteile entfallen. Somit kann das Gewicht und / oder Volumen des Batteriegehäuses, Batteriepacks und / oder Batteriemoduls weiter reduziert werden.
