Safety device for limitation of internal short-circuit current of automotive battery, has contact circuit breakers released automatically during accident, designed as pyrotechnic fuses and interrupting series connection of cells

摘要

The device has contact circuit breakers released automatically during an accident. The circuit breakers interrupt a series connection of cells (Z) of an automotive battery (FB) in a specific place. The contact circuit breakers are designed as pyrotechnic fuses (PTS1, PTS2). The cells and the pyrotechnic fuses are arranged in a housing (G). The fuses are controlled by a pyrotechnic controller (PTE). The cells have positive and negative connections and have a voltage less than 10 voltages.
