The battery extrusion and nail penetration integrated machine is a core device for lithium battery safety performance testing. It integrates two major functions of extrusion testing and nail penetration testing, and can simulate extreme scenarios such as external extrusion and puncture that batteries may encounter during use, transportation, storage or handling. It verifies the safety and stability of batteries under mechanical abuse conditions, serving as a crucial testing device to ensure battery products comply with safety standards.

Fix the battery between rigid pressure plates, and apply controllable pressure via a servo motor-driven indenter until the battery deforms or the set force value is reached. Real-time changes in battery voltage and temperature are monitored throughout the process to simulate the failure behavior of batteries under external extrusion force.

Use steel needles with specified diameters (optional: φ3~φ10mm) to penetrate the battery cell at a set speed, simulate the internal short circuit scenario of the battery, and monitor thermal runaway risks and safety performance.
