  • the known battery management systems have a battery management unit and at least one cell monitoring module.
  • the cell monitoring module monitors a battery cell or a plurality of battery cells of a battery, such as those used in electric vehicles or hybrid vehicles, with regard to their functionality and the state of charge.
  • the electrical signals detected by each battery cell by the at least one cell monitoring module are at least partially preprocessed in the cell monitoring module and forwarded by the cell monitoring module to the battery management unit for further processing.
  • further physical variables of the battery are recorded and processed in the battery management unit.
  • the battery monitoring unit usually works with a standardized, ie standardized, data protocol such as CAN, the data protocols of the respective manufacturers of the cell monitoring modules are used in the cell monitoring modules. Accordingly, the electrical data and / or electrical signals can not simply be forwarded from the at least one cell monitoring module to the battery monitoring unit because the data protocols are incompatible with one another.
  • the forwarding of the electrical data and / or electrical signals therefore takes place in the known battery management systems in two ways: On the one hand, a standardized interface is installed in the at least one cell monitoring module. This is, depending on the number of required for the battery cell monitoring cell monitoring modules, consuming and costly.
  • a proprietary interface is installed in the battery management unit, ie an interface which converts the data protocol used by the respective manufacturer of the cell monitoring module into the standardized data protocol used in the battery management unit.
  • the object of the present invention is to enable a data exchange between the at least one cell monitoring module and the battery management unit without having to adapt the cell monitoring module or the battery management unit.
  • An essential advantage of the invention lies in particular in that interfaces do not have to be installed in the cell monitoring module or in the battery management unit for the data and / or signal exchange required between the at least one cell monitoring module and the battery management unit. Especially with the high number of battery cells for vehicle batteries for example, this leads to a considerable simplification and thus to a considerable cost Reduction compared to the known from the prior art alternative to equip each cell monitoring module with an interface. In contrast to the further alternative, namely to install a proprietary interface in the battery management unit, the flexibility of the battery management unit is not impaired in the solution according to the invention. This is especially true when using a standardized transmission standard such as CAN.
  • the adapter according to the invention can be connected to the battery management unit and / or the at least one cell monitoring module merely by signal transmission by means of the system connection and / or the module connection.
  • the adapter to the battery management unit and / or the cell monitoring module corresponding mechanical coupling means. In this way, a stable and reliable mechanical and electrical connection between the adapter on the one hand and the battery management unit and / or the at least one cell monitoring module on the other side is ensured.

  • the data protocol of the manufacturer of the cell monitoring modules 6, ie a proprietary data protocol in use.
  • the proprietary data protocol of cell monitoring modules 6 is not compatible with the CAN data protocol. Accordingly, it is not possible to process the electrical data and / or electrical signals of the cell monitoring modules 6 directly in the battery management unit 4.
  • the battery management system 2 has an adapter 8, with a module connection 8.1, a system connection 8.2 and a conversion unit 8.3.
  • the conversion unit 8.3 can be connected via the module connection 8.1 to one of the cell monitoring modules 6 in a data-transmitting and / or signal-transmitting manner.
