摘要： An apparatus and method for conducting a nail penetration test for a secondary battery are provided. The apparatus for conducting the nail penetration test includes: a stage on which the secondary battery, which is an object of the nail penetration test, is fixed; a nail penetration unit including a nail elevating/lowering means; a voltage measuring unit configured to repeatedly measure a short-circuit voltage of the secondary battery with a time interval during the nail penetration test; and a controller operably coupled to the voltage measuring unit. The controller periodically receives a short-circuit voltage from the voltage measuring unit, determines a short-circuit current allowing the received short-circuit voltage to be applied between outermost nodes of an equivalent circuit which models the secondary battery whenever the short-circuit voltage is received, and visually outputs a change in the determined value of the short-circuit current according to time through a display unit.
