Protection system for protecting a battery system

A protection system for overcurrent protection in a battery system, with:

• a protection element for interrupting an electric current path in the battery system,
• an acquisition unit for determining acquisition information which is specific for an electric current of the electric current path,
• an electronic processing unit for performing a comparison of the acquisition information with an adjustable protection specification to detect an overcurrent condition,
• wherein the electronic processing unit is operatively connected to the protection element for activating the protection element in response to the comparison such that the interruption occurs upon positive detection of the overcurrent condition in accordance with an adjustable activating characteristic,
• wherein the adjustable protection specification comprises a plurality of adaptable protection characteristic curves which are adaptable to an operating range of the battery system in different ways from one another in order to perform the positive detection of the overcurrent condition at least for a plurality of value ranges or parameters of the operating range by comparison with the respective protection characteristic curves, wherein the protection element is configured as a pyrotechnic switch, whereby a bolt is driven through a perforated conductor, wherein the conductor is an electrical conductor which is connected to contacts of the protection element such that the electrical conductor is part of a circuit of the battery system.
