Battery Extrusion and Puncture Machine

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.

• GB 31241-2014/2022 Safety Requirements for Lithium-ion Batteries and Battery Packs Used in Portable Electronic Products
• GB/T 31485-2015 Safety Requirements for Traction Batteries of Electric Vehicles
• International safety standards including UL 1642, IEC 62133, UN 38.3, etc.

• Dual-test Integration for High-efficiency Detection: Integrated with two core abuse tests, extrusion and needle penetration. No need for equipment replacement, which greatly boosts detection efficiency and reduces equipment investment costs.
• Precise Control & Reliable Data: Equipped with a servo drive system and high-precision sensors to realize closed-loop control of extrusion force, displacement and speed. It collects real-time data of pressure, displacement, voltage and temperature, and supports the export of complete test reports to meet quality inspection traceability requirements.
• Multiple Safety Protections to Eliminate Risks: Featuring an explosion-proof cavity design, transparent protective observation window, over-temperature/over-pressure/over-current protection and emergency stop button. It effectively isolates fire and explosion hazards during testing and ensures the safety of operators.
• User-friendly Operation & Easy Maintenance: Humanized touch screen interface enables one-click parameter setting. Modular fixture design allows convenient sample loading and unloading. The equipment is easy to clean and maintain, cutting down long-term operating costs.

Our machine is packed by standard export wooden box, ensuring safe protection during transportation. We've delivered many testing machines abroad by sea or by air without damage.
