Nail for penetration test of secondary battery and secondary battery penetration test device using thereof

摘要

A nail for a secondary battery penetration experiment and an experiment device for a secondary battery penetration using the same are disclosed. A nail for a secondary battery penetration test according to the present invention comprises: a conductive nail body part having an inner hollow and receiving an external force and being press-fitted into a secondary battery; And a sensor module disposed in the hollow of the nail body to generate an induction current according to a magnetic field formed by a current flowing in the nail body portion. The sensing module acquires various sensing information through a nail to measure a calorific value of the secondary battery And improve the reliability and accuracy of the safety assessment.
