Abstract:
(EN) A protection circuit for a battery monitoring device for monitoring a battery module protects a circuit from overcurrent without blowing out a path. A signal line group (12) of the protection circuit (11) comprises a plurality of voltage signal lines (12A), wherein the voltage signal lines (12A) are connected to the electrode portions (2C) of a plurality of unit batteries (4) or the electrode portions (2A, 2B) of a battery module (2), respectively. A first protection circuit (13) is provided with a plurality of Zener diodes (16), wherein each of the Zener diodes (16) is connected between the signal lines of the plurality of voltage signal lines (12A) and in parallel with each of the unit batteries (4). A resistor portion group (15) comprises a plurality of resistor portions (19), wherein each of the resistor portions (19) is interposed between the Zener diodes (16) and the unit batteries (4) in each of the voltage signal lines (12A) and limits current. A second protection circuit unit (14) is provided with a plurality of varistors (17), wherein each of the varistors (17) is connected between the signal lines of the plurality of voltage signal lines (12A) and in parallel with each of the unit batteries (4).
