OVERCURRENT CIRCUIT BREAKER FOR POUCH CELL BATTERY

The present invention provides an overcurrent circuit breaker for a pouch cell battery, comprising a first electrical connection plate, a second electrical connection plate, a current-interrupting element, and a protective housing. The first electrical connection plate electrically connects a first busbar of the pouch cell battery, while the second electrical connection plate connects a first electrode. The current-interrupting element forms a current path between the joining plates and is positioned inside a protective housing made of a flame-retardant material with insulating and heat-insulating properties. The overcurrent circuit breaker, located inside the pouch cell battery, provides an active protection for the battery cell module by preventing excessive current during charging or discharging.
