1. A method for locating a battery module among multiple battery modules of a traction battery that are electrically connected to one another, said method comprising:

  • measuring an electrical potential at each of the battery modules in real time relative to a potential reference that is common to the battery modules,subtractively computing potentials between the battery modules using the measured electrical potentials,deriving a positional relationship for the battery modules from the subtractively computed potentials,retrieving a voltage dropped across the battery module that is to be located using a module controller that is univocally denoted within the traction battery, andlocating the battery module on the basis of the positional relationship within the traction battery using the retrieved voltage and the substractively computed potentials.
