    专利说明:

    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.
    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.
    The object of the invention is to avoid these disadvantages and to reduce assembly costs and manufacturing costs.
    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.
    Power electronics and sensors can be arranged on separate boards or on a common board.
    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 electrical contact and / or at least one board-side electrical plug-in connection, wherein the battery-side and piatinenseitigen contacts and / or connectors are directly and wirelessly connectable,
    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.
    The connections for the temperature sensors and / or for the electrical heating device 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.
    Because all contacts and / or plug-in connections are arranged on the upper side of the battery module, all connections between the electronics and the battery or sensors have the same plug-in direction.
    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.
    The invention will be explained in more detail below with reference to FIG.
    2 shows the top of the energy store in detail, FIG. 3 shows a board in a bottom view, FIG. 4 shows a board in a plan view, FIG. 5 shows an assembly process of a board, and FIG 6 to 8 an energy storage with attached board in different views.
    The electrical energy storage 1 includes at least one battery module! 2 with a stack 3 of individual modules 5, not shown in detail, wherein at each end of the stack in each case an end plate 6 »t v * * ·« ·% * · > is arranged. Each individual module 5 has a single cell frame 7 for receiving at least one individual cell.
    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.
    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.
