Extrusion Needle Battery Test Machine OEM ODM with Adjustable Frame

1. Product Name and Purpose

2. Product Features

• Robust and Adjustable Frame
  • The machine is constructed with a heavy-duty frame, typically made of high-strength steel, to ensure stability and durability during the testing process. The frame is designed to accommodate different battery sizes and shapes, with adjustable fixtures and clamps. This flexibility enables the testing of a wide range of battery chemistries and form factors, from small coin-cell batteries to large-format lithium-ion packs used in electric vehicles and energy storage systems. The adjustable components are precisely calibrated, allowing for quick and accurate setup, minimizing the time required between different test runs.
• Precision Extrusion Needle Mechanism
  • The extrusion needle is a critical component of the machine. It is made of a hardened and corrosion-resistant material, such as stainless steel or tungsten carbide, to ensure it can withstand the forces exerted during testing without deforming or breaking. The needle's diameter and length can be adjusted according to the specific requirements of the battery being tested. The machine is equipped with a highly accurate force control system that can apply a consistent and precisely measured extrusion force. This force can range from a few Newtons for small, delicate batteries to several hundred Newtons for larger, more robust ones. The control system allows for fine-tuning of the force application rate, enabling the simulation of different impact scenarios, from slow, gradual compression to rapid, sudden jolts.
• Advanced Sensing and Monitoring Capabilities
  • To comprehensively assess the battery's response to the extrusion test, the machine is outfitted with a suite of sensors. Voltage and current sensors are installed to monitor any electrical changes within the battery during the test. A sudden increase in current or a drop in voltage could indicate the onset of a short circuit or internal damage. Temperature sensors are strategically placed on the battery's surface and, in some cases, within the cell to measure any temperature fluctuations. An abnormal temperature rise might suggest a potential thermal runaway. Pressure sensors are also incorporated to measure the internal pressure of the battery, providing valuable insights into its structural integrity and the likelihood of leakage or rupture. These sensors are connected to a state-of-the-art data acquisition system that records and analyzes the data in real-time. The data acquisition system is highly configurable, allowing users to set custom sampling rates and trigger thresholds. It can also generate detailed reports and graphs, facilitating in-depth analysis and comparison of different test results.
