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

摘要

Disclosed are a nail for a penetration test of a secondary battery and a device for a penetration test of a secondary battery using the same. According to the present invention, the nail for a penetration test of a secondary battery comprises: a conductive nail body unit having an internal hollow inserted in the secondary battery by receiving an external force; and a sensor module unit arranged on the inner hollow of the nail body unit for generating an induced current with respect to a magnetic field formed by the current flowing through the nail body unit. The nail for a penetration test of a secondary battery improves the accuracy and the reliability of a safety evaluation and a calorific value of the secondary battery by obtaining various sensing information through the nail.
