Die Kühlvorrichtung umfasst eine am Zellenverbund angeordnete Kühlplatte und am Zellenverbund ist eine Andruckplatte zum Andrücken der Batteriezellen an die Kühlplatte angeordnet. Dabei weist die Andruckplatte wenigstens eines der elektrischen Bauelemente auf. Zellenverbund und Kühlplatte sind durch um sie herum geführte Spannelemente aneinander gepresst, wobei die Spannelemente elastische Mittel enthalten.The battery according to the invention has a plurality of cell cells forming a battery cell, a cooling device for controlling the temperature of the battery cells and electrical components for monitoring and / or control of battery functions.

Die Verwendung einer Kühlplatte ist vorteilhaft, da eine Kühlplatte eine einfache und kostengünstige Vorrichtung zur Temperierung der Batteriezellen ist. Durch die Integration elektrischer Bauelemente der Batterie in die Andruckplatte wird die Andruckplatte gleichzeitig zum Andrücken der Kühlplatte an die Batteriezellen und als Träger für elektrische Bauelemente der Batterie verwendet. Dadurch werden vorteilhaft Bauraum und Herstellungskosten der Batterie eingespart. Durch die Verwendung von Spannelementen mit elastischen Mitteln können Ausdehnungen der Zellen, welche durch thermische Einflüsse oder durch Innendruckveränderungen hervorgerufen werden können, ausgeglichen werden, ohne dass die Spannungen im Zellblock kritische Werte überschreiten oder der erforderliche Anpressdruck der Zellen untereinander oder zur Kühlplatte verloren geht.The use of a cooling plate is advantageous because a cooling plate is a simple and inexpensive device for controlling the temperature of the battery cells. By integrating electrical components of the battery in the pressure plate, the pressure plate is used simultaneously for pressing the cooling plate to the battery cells and as a carrier for electrical components of the battery. As a result, space and manufacturing costs of the battery are advantageously saved. By using tensioning elements with elastic means, it is possible to compensate expansions of the cells, which can be caused by thermal influences or by internal pressure changes, without the stresses in the cell block exceeding critical values or the required contact pressure of the cells with each other or with the cooling plate being lost.
Eine vorteilhafte Ausgestaltung sieht vor, dass die Spannelemente selbst elastisch ausgebildet sind. Damit kann eine sichere Verbindung mit hoher Lebensdauer erreicht werden. Die Batteriezellen werden mit konstanter Kraft an die Kühlplatte gepresst, so dass ein guter thermischer Kontakt zwischen den Batteriezellen und der Kühlplatte ermöglicht wird.An advantageous embodiment provides that the clamping elements themselves are designed to be elastic.

This design can be inexpensively manufactured by simple means.
Vorteilhaft ist es, jeweils eine Zugfeder oberhalb der Andruckplatte, unterhalb der Kühlplatte sowie an einer Außenseite der vorderen Polplatte und an einer Außenseite der hinteren Polplatte anzuordnen. Damit wird eine definierte Anpresskraft sowohl in Längsrichtung wie auch in dazu senkrechter Richtung gewährleistet.It is advantageous to arrange a respective tension spring above the pressure plate, below the cooling plate and on an outer side of the front pole plate and on an outer side of the rear pole plate. This ensures a defined contact force both in the longitudinal direction and in the direction perpendicular thereto.
Ferner ist es möglich, dass die Spannelemente als Spannbänder ausgeführt sind, und dass zwischen den Spannbändern und den von ihnen umschlossenen Bauteilen sich ein elastisches Element befindet. Diese Gestaltung gewährleistet eine gleichmäßige Lastverteilung.Furthermore, it is possible that the clamping elements are designed as clamping bands, and that between the clamping bands and the components enclosed by them is an elastic element. This design ensures a uniform load distribution.
Hierbei wird ebenfalls eine vorteilhafte Ausführung dadurch geschaffen, dass jeweils ein elastisches Element oberhalb der Andruckplatte, unterhalb der Kühlplatte sowie an einer Außenseite der vorderen Polplatte und an einer Außenseite der hinteren Polplatte angeordnet wird, um eine definierte Anpresskraft sowohl in Längsrichtung wie auch in dazu senkrechter Richtung zu gewährleisten.In this case, an advantageous embodiment is also provided by the fact that in each case an elastic element above the pressure plate, below the cooling plate and on an outer side of the front pole plate and on an outer side of the rear pole plate is arranged to a defined contact force both in the longitudinal direction and in perpendicular thereto To ensure direction.

Dadurch sind die Andruckplatte, die Batteriezellen und die Kühlplatte geometrisch einfach zueinander angeordnet, woraus eine kostengünstige Herstellung und Montage der Batterie resultiert.As a result, the pressure plate, the battery cells and the cooling plate geometrically simple to each other, resulting in a cost-effective production and installation of the battery results.
Durch die Anordnung einer Wärmeleitplatte zwischen Batteriezellen und Kühlplatte kann die Kühlwirkung weiter verbessert werden.By arranging a heat conducting plate between the battery cells and the cooling plate, the cooling effect can be further improved.
Elektrische Bauelemente auf der Andruckplatte sind bevorzugt ein Zellspannungsausgleichselement zum Ausgleich unterschiedlicher Ladungszustände von Batteriezellen und/oder ein Zellspannungsüberwachungselement.Electrical components on the pressure plate are preferably a cell voltage compensation element for compensating different charge states of battery cells and / or a cell voltage monitoring element.
