This measurement is used to monitor and diagnose the operation and function of the energy storage cell.
  • the safety contact used for this purpose can - if necessary even at the same time - serve to discharge the energy storage cell or be provided exclusively for the purpose of measuring the operating parameter.

  • Condition parameters of the type mentioned above can give the operator important information on the further treatment (for example, transport, storage or recycling) of the energy storage cell.
  • Both the measurement of an operating parameter and the determination of a state parameter can be carried out by means of devices supplied by the energy storage cell, for example an electric vehicle, or devices permanently installed in the components thereof.

This makes it possible to check compliance with the respective parameter range individually for the type of energy storage cell.
  • the type of energy storage cell can be determined by the at least one measured operating parameter and / or the at least one specific state parameter, for example by comparison with a ner stored in an external meter table with eligible for the present application types of energy storage cells.

  • the energy released during the discharge is preferably converted into heat, which is dissipated through the housing of the energy storage cell by means of already existing cooling devices. Since the discharge of the energy storage cell is generally carried out in the expanded state of the energy storage cell after the current interruption device has been triggered, the energy storage cell can then also be coupled with further, more efficient cooling devices.

  • This embodiment can be implemented particularly easily if the energy storage cell already has a flexible casing (for example a so-called pouch or coffee bag cell). On the other hand, if the energy storage cell has a rigid shell, breakthroughs can be provided at certain points of the housing which are reclosed with a flexible material onto which the pressure is then applied from outside to trigger the discharge.

  • the shell 2 is thinner and thus more sensitive to pressure than in the other areas to selectively transfer the pressure applied to them on the underlying security contacts.
  • the two safety contacts are connected in series, so that only a simultaneous pressure on both safety contacts closes a circuit inside the cell, which leads there to a discharge of the cell 1.
  • the two areas 7, 8 are expediently so small that the underlying safety contacts during manual handling of the cell 1 not accidentally with the fingers can be triggered. Rather, it is intended to trigger the safety contacts by the simultaneous pressure with two thin pins or with a special pliers on the areas 7, 8. Since in a ready-assembled battery module, the individual cells 1 are arranged in a space-saving manner flat and close to each other, it is already purely mechanically excluded in the embodiment of FIG. 2 that a discharge of the cell 1 via the safety contacts in the installed state Cell 1 is done. This is advantageous because a discharge within the battery module could lead to problems with the heat dissipation in cells with a high energy density, if the battery module's own cooling system is thus overwhelmed.
