Abstract

A method for locating a battery module among multiple battery modules of a traction battery that are electrically connected to one another, having the following features: an electrical potential is measured at each of the battery modules in real time relative to a potential reference that is common to the battery modules; the potentials are used to subtractively compute voltages between the battery modules; a positional relationship for the battery modules is derived from the voltages; a module controller that is univocally denoted within the traction battery is used to retrieve a voltage dropped across the battery module that is to be located; and the retrieved voltage and the computed voltages are used to locate the battery module on the basis of the positional relationship within the traction battery. Also described is a corresponding apparatus, a corresponding computer program and a corresponding storage medium.
