Nail penetration test device

Abstract

Disclosed is a nail penetration test device, which can improve the performance of nail penetration tests. The device includes: a voltage acquisition module, including a first connection port and a second connection port, where the first connection port is connected to a nail, and the second connection port is connected to a first electrode terminal of a battery cell; and a nail mechanism, configured to control the nail to move toward the battery cell, where the voltage acquisition module is configured to detect a voltage between the nail and the first electrode terminal during the movement of the nail toward the battery cell, and the voltage is used to determine an initial penetration position of the nail on the battery cell.

Dependencies are inferred from the claim text.
