Computer Servo Compression Nail Penetration Test Machine

Product Overview

This computer-controlled battery safety test system reproduces compression and nail penetration conditions that traction lithium batteries may experience during use. It applies controlled force through a servo motor and screw mechanism, allowing laboratory teams to observe possible battery responses under programmed compression conditions. Adjustable force, speed, travel, hold time, voltage monitoring, and multi-stage displacement control provide a practical platform for repeatable abuse-test procedures.

The equipment is intended for power lithium battery development, cell safety evaluation, quality verification, and failure-analysis work. It supports force-, displacement-, or voltage-based test conditions, enabling teams to establish procedures around a defined load, deformation target, or voltage-drop threshold. The included tungsten carbide needles also support penetration testing alongside plate-based compression testing within the same protected test environment.

Built around a vertical compression structure and a separated control arrangement, this unit prioritizes controlled operation during demanding battery tests. A flame-retardant stainless-steel inner chamber, explosion-protected observation window, automatic pressure-relief provision, exhaust capability, remote video monitoring, carbon dioxide fire-extinguishing system, and emergency stop function support informed observation while helping keep personnel separated from the active test area.

Key Features

• Servo-Driven Compression Control: A servo motor drives the screw-based loading mechanism for adjustable compression from 1 to 20 kN. The system provides force error of no more than +/-1% of full scale, supporting dependable execution of defined load conditions.

• Programmable Multi-Stage Displacement: The platen can descend to a defined position, dwell, continue to a second displacement stage, dwell again, and repeat the sequence through the final programmed position. This control method supports deformation-based test protocols that require staged loading and timed holds rather than a single continuous stroke.

• Multiple Automatic Return Conditions: The system can return immediately or after a specified hold when the set force is reached. It can also return or hold after a selected voltage-drop value is detected, giving laboratories flexibility to align termination behavior with their internal test method.

• Adjustable Speed Across Compression and Penetration Tests: Compression speed is adjustable from 1 to 900 mm/min, while nail penetration speed is 1 to 40 mm/s. Speed accuracy is no more than +/-1% of full scale, helping users maintain consistent motion settings across comparative test programs.

• Integrated Voltage and Temperature Acquisition: The unit includes temperature and voltage acquisition capability, with 1 mV voltage resolution. Test data are computer-controlled for stable, real-time remote collection and can be saved and printed as Excel documents.

• Protected Observation Environment: A 400 x 400 mm explosion-proof glass viewing window incorporates explosion-proof film and an internal steel-mesh structure. A high-brightness energy-saving explosion-proof lamp illuminates the test space for direct visual observation during testing.

• Containment and Pressure-Relief Provisions: The vertical chamber uses flame-resistant material and SUS#304 stainless steel for the inner enclosure, with a powder-coated cold-rolled-steel exterior. A magnetically retained 300 x 300 mm rear pressure-relief door opens under strong airflow to reduce explosion impact.

• Independent Exhaust and Fire Control: The independently controlled 150 mm diameter top exhaust system can automatically detect smoke generated by a test sample and discharge it through ducting. A remotely controllable carbon dioxide fire-extinguishing system provides an additional protective response capability.

• Remote and Local Operating Arrangement: The chamber and control section are separated by up to 5 m, with an independent controller that supports both local and remote control. A high-definition camera monitoring system in the test area can also be remotely controlled to support accurate observation and recorded test review.

• Purpose-Built Penetration Tooling: The supplied tungsten carbide needle set includes six each of Phi3, Phi4, and Phi6 x 100 mm needles, for 18 needles in total. This provides several reference-backed needle diameters for battery penetration test preparation.
