Beschreibung [0001] Die Erfindung betrifft einen elektrischen Energiespeicher, insbesondere für Kraftfahrzeuge, mit zumindest einem Batteriemodul, welcher mit einer Sensor- und/oder Leistungselektronik elektrisch leitend verbunden ist, wobei die Sensor und/oder Leistungselektronik auf zumindest einer Platine, vorzugsweise auf einer einzigen Platine angeordnet ist und wobei die Platine direkt auf den Batteriemodul aufgesteckt ist.Description: [0001] The invention relates to an electrical energy store, in particular for motor vehicles, having at least one battery module which is electrically connected to a sensor and / or power electronics, wherein the sensor and / or power electronics on at least one board, preferably on a single Board is arranged and wherein the board is attached directly to the battery module.

[0002] Es ist bekannt einen Batteriemodul eines elektrischen Energiespeichers über einen gebündelten Kabelbaum mit Steckverbindungen mit der Sensor- und Leistungselektronik zu verbinden. Dies erfordert allerdings einen relativ hohen Montageaufwand.It is known to connect a battery module of an electrical energy storage device via a bundled wiring harness with connectors to the sensor and power electronics. However, this requires a relatively high installation costs.

[0003] Aus den Druckschriften WO 2010/031 856 A2 und DE 198 10 746 A1 sind Platinen zum Verbinden mehrerer Flachzellen von Energiespeichereinheiten bekannt, wobei auf den Platinen jeweils Überwachungseinrichtungen zum Übenwachen der Temperatur und der Spannung der einzelnen Flachzellen angeordnet sind. Die Platinen weisen Kontaktelemente auf, die mit entsprechenden Kontakten der Flachzellen durch Aufstecken kabellos verbunden werden können.From the documents WO 2010/031 856 A2 and DE 198 10 746 A1 boards for connecting a plurality of flat cells of energy storage units are known, in each case monitoring devices for monitoring the temperature and the voltage of the individual flat cells are arranged on the boards. The boards have contact elements that can be connected wirelessly with corresponding contacts of the flat cells by plugging.

[0004] Aufgabe der Erfindung ist es, diese genannten Nachteile zu vermeiden und den Montageaufwand sowie die Herstellungskosten zu reduzieren.The object of the invention is to avoid these disadvantages and to reduce the assembly costs and the manufacturing cost.

[0005] Erfindungsgemäß wird dies dadurch erreicht, dass die Platine in einem Rahmen vormontiert ist.According to the invention this is achieved in that the board is preassembled in a frame.

[0006] Leistungselektronik und Sensorik können dabei auf getrennten Platinen oder auf einer gemeinsamen Platine angeordnet sein.Power electronics and sensors can be arranged on separate boards or on a common board.

[0007] Besonders vorteilhaft ist es dabei, wenn einerseits der Batteriemodul an der der Platine zugewandten Seite, vorzugsweise an der Oberseite, zumindest einen batterieseitigen elektrischen Kontakt und/oder zumindest eine batterieseitige elektrische Steckverbindung, und andererseits die Platine an der dem Batteriemodul zugewandten Seite zumindest einen entsprechenden platinenseitigen elektrischen Kontakt und/oder zumindest eine platinenseitige elektrische Steckverbindung aufweist, wobei die batterieseitigen und platinenseitigen Kontakte und/oder Steckverbindungen unmittelbar und kabellos miteinander verbindbar sind. Zumindest ein elektrischer Kontakt und/oder eine elektrische Steckverbindung kann dabei ein Anschluss für einen Temperatursensor des Batteriemoduls sein. Weiters kann zumindest ein elektrischer Kontakt und/oder eine elektrische Steckverbindung ein Anschluss für eine elektrische Heizeinrichtung, vorzugsweise einer Heizfolie, des Batteriemoduls sein. Ferner kann vorgesehen sein, dass zumindest ein elektrischer Kontakt und/oder eine elektrische Steckverbindung ein Anschluss für eine Spannungsüberwachung zumindest einer Batteriezelle ist.It is particularly advantageous if, on the one hand, the battery module on the side facing the board, preferably at the top, at least one battery-side electrical contact and / or at least one battery-side electrical connector, and on the other hand, the board on the battery module side facing at least a corresponding board-side electrical contact and / or at least one board-side electrical connector, wherein the battery-side and board-side contacts and / or connectors are directly and wirelessly connected to each other. At least one electrical contact and / or an electrical plug connection can be a connection for a temperature sensor of the battery module. Furthermore, at least one electrical contact and / or one electrical plug connection can be a connection for an electrical heating device, preferably a heating foil, of the battery module. Furthermore, it can be provided that at least one electrical contact and / or one electrical plug connection is a connection for voltage monitoring of at least one battery cell.

[0008] Die Anschlüsse für die Temperatursensoren und/oder für die elektrische Heizeinrichtung können dabei vorteilhafterweise in einen Einzelzellenrahmen des Batteriemoduls integriert sein. Zumindest ein Anschluss für eine Spannungsüberwachung zumindest einer Zelle kann in den Busbar integriert sein.The connections for the temperature sensors and / or for the electric heater can be advantageously integrated into a single cell frame of the battery module. At least one connection for voltage monitoring of at least one cell can be integrated in the busbar.

[0009] Dadurch, dass sämtliche Kontakte und/oder Steckverbindungen an der Oberseite des Batteriemoduls angeordnet sind, weisen alle Anschlüsse zwischen der Elektronik und der Batterie bzw. Sensorik die gleiche Steckrichtung auf.Characterized in that all contacts and / or connectors are arranged on the upper side of the battery module, all connections between the electronics and the battery or sensors have the same direction of insertion.

[0010] Durch die direkte Steckverbindung zwischen Batteriemodul und Platine kann auf lose Kabeln im Batteriemodul verzichtet werden. Dies wirkt sich sehr vorteilhaft auf die Kosten in Folge der reduzierten Teileanzahl und des minimalen Montageaufwandes aus.Due to the direct connection between the battery module and board can be dispensed with loose cables in the battery module. This has a very advantageous effect on the costs due to the reduced number of parts and the minimum assembly costs.

[0011] Die Erfindung wird im Folgenden an Hand der Fig. näher erläutert.The invention will be explained in more detail below with reference to FIG.

[0012] Es zeigen [0013] Fig. 1 einen erfindungsgemäßen Energiespeicher in einer Schrägansicht, [0014] Fig. 2 die Oberseite des Energiespeichers im Detail, 1 /61 shows an energy store according to the invention in an oblique view, [0014] FIG. 2 shows the top of the energy store in detail, 1/6

Ein Teil der Anschlüsse dient zum Anschluss von im Batteriemodul 2 integrierten Temperatursensoren, zur Spannungsüberwachung und zum Spannungsausgleich der einzelnen Zellen (Balancing), sowie zum Anschluss von Heizeinrichtungen, beispielsweise Heizfolien zwischen den Einzelmodulen 5. Die Anschlüsse für die Temperatursensoren sind mit Bezugszeichen 15, die Balancing- Anschlüsse für die Zellen mit 16 und die Anschlüsse für die Heizeinrichtung mit Bezugszeichen 17 bezeichnet.On the upper side 8 of the battery module 2, at least one circuit board 9 with power electronics 10 and / or sensor electronics 11 is arranged. At the battery module 2 facing bottom 12 of the board 9 platinum-side contacts and / or connectors 13 are arranged, which fit on corresponding battery-side contacts and / or connectors 14 on the upper side 8 of the battery module 2. Some of the connections are used to connect temperature sensors integrated in the battery module 2, to monitor the voltage and to balance the individual cells (balancing), and to connect heating devices, for example heating foils, between the individual modules 5. The connections for the temperature sensors are denoted by reference numeral 15 Balancing connections for the cells with 16 and the connections for the heater with reference numeral 17 denotes.

[0021] Alle Kontakte und Steckverbindungen 13, 14 sind im Wesentlichen vertikal ausgerichtet, sodass ein einfaches Aufstecken der Platine 9 auf das Batteriemodul 2 gewährleistet ist. Zur Erleichterung der Zentrierung bei der Montage ist die Platine 9 in einem beispielsweise aus Kunststoff bestehenden Rahmen 18 vormontiert. Mit 19 sind in Fig. 8 entsprechende Zentrierungen des Rahmens 18 bezeichnet. 2/6All contacts and connectors 13, 14 are aligned substantially vertically, so that a simple plugging the board 9 is ensured on the battery module 2. To facilitate the centering during assembly, the circuit board 9 is pre-assembled in an existing example of plastic frame 18. With 19 corresponding centerings of the frame 18 are designated in Fig. 8. 2.6
