Description

ELEKTRISCHER ENERGIESPEICHER  ELECTRIC ENERGY STORAGE

Die Erfindung betrifft einen elektrischen Energiespeicher, insbesondere für Kraftfahrzeuge, mit zumindest einem Batteriemodul, welcher mit einer Sensor- und/ oder Leistungselektronik elektrisch leitend verbunden ist. The invention relates to an electrical energy store, in particular for motor vehicles, with at least one battery module, which is electrically connected to a sensor and / or power electronics.

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 cable harness with plug connections to the sensor and power electronics. However, this requires a relatively high installation costs.

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

Erfindungsgemäß wird dies dadurch erreicht, dass die Sensor und/oder Leistungselektronik auf zumindest einer Platine, vorzugsweise auf einer einzigen Platine angeordnet ist und dass die Platine direkt auf den Batteriemodul aufgesteckt ist. According to the invention this is achieved in that the sensor and / or power electronics is arranged on at least one circuit board, preferably on a single board and that the board is attached directly to the battery module.

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.

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 miteinanderverbindbar sind. It is particularly advantageous if, on the one hand, the battery module on the side facing the board, preferably on 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 one corresponding board side having 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 connectable.

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. 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.

Die Anschlüsse für die Temperatursensoren und/oder für die elektrische Heizeinrichtung können dabei vorteilhafterweise in einen Einzelzellenrahmen des Bat- teriemoduls integriert sein. Zumindest ein Anschluss für eine Spannungsüberwachung zumindest einer Zelle kann in den Busbar integriert ist. The connections for the temperature sensors and / or for the electrical heating device can advantageously be divided into a single cell frame of the battery. be integrated teriemoduls. At least one connection for voltage monitoring of at least one cell can be integrated in the busbar.

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. Because all the contacts and / or plug-in connections are arranged on the upper side of the battery module, all the connections between the electronics and the battery or sensors have the same plug-in direction.

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. The direct connection between the battery module and the board eliminates the need for 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.

Die Erfindung wird im Folgenden anhand der Figuren näher erläutert. Es zeigen : The invention will be explained in more detail below with reference to FIGS. Show it :

Fig. 6 bis Fig. 8 einen Energiespeicher mit aufgesetzter Platine in verschiedenen Ansichten. Fig. 6 to Fig. 8 shows an energy storage with attached board in different views.

Der elektrische Energiespeicher 1 beinhaltet zumindest einen Batteriemodul 2 mit einem Stapel 3 an nicht weiter dargestellten Einzelzellen aufweisenden Einzelmodulen 5, wobei an jedem Ende des Stapels jeweils eine Endplatte 6 angeordnet ist. Jeder Einzelmodul 5 weist einen Einzelzellenrahmen 7 zur Aufnahme zumindest einer Einzelzelle auf. The electrical energy storage device 1 includes at least one battery module 2 with a stack 3 of individual modules 5, not shown in detail, wherein an end plate 6 is arranged at each end of the stack. Each individual module 5 has a single cell frame 7 for receiving at least one individual cell.

Auf der Oberseite 8 des Batteriemoduls 2 ist zumindest eine Platine 9 mit Leistungselektronik 10 und/oder Sensorelektronik 11 angeordnet. An der dem Batteriemodul 2 zugewandten Unterseite 12 der Platine 9 sind platineseitige Kontakte und/oder Steckverbindungen 13 angeordnet, welche auf entsprechende batterieseitige Kontakte und/oder Steckverbindungen 14 auf der Oberseite 8 des Batteriemoduls 2 passen. 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 to corresponding battery-side contacts and / or connectors 14 on the top 8 of the battery module 2. A part of the connections serves 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, 16 denotes the balancing connections for the cells and 17 denotes the connections for the heating device.

Alle Kontakte und Steckverbindungen 13, 14 sind im wesentlichen vertikal ausgerichtet, so dass 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. All 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.
