⚙️ Key Features
-
🛡️Explosion-proof and Flame-retardant PerformanceThe inner box is made of SUS304 stainless steel, equipped with a dedicated pressure relief door and high-temperature resistant flame-retardant sealing strip, ensuring safety and reliability.
-
🎯High-precision Force and Displacement ControlAdjustable squeezing force: 5kN – 20kN (customizable for larger ranges) Precise control of needle insertion speed: 0.1mm/s – 15mm/s Supports multiple shutdown modes: stops when the deformation reaches 30% of the maximum, triggered by voltage drop, etc.
-
⚡Servo Drive SystemDriven by servo motors, which is more precise, has lower noise and eliminates the risk of oil leakage compared to the hydraulic system.
-
🖥️Remote Safety OperationThe operation console and the test box are designed as separate units. They can be remotely controlled via a computer or a touch screen, ensuring the safety of the operators throughout the process.

▶️ Workflow
❓ FAQ
Our equipment offers an all-in-one solution. By quickly changing the fixtures, two functions can be achieved at the same workstation, thus saving laboratory space.
The system adopts closed-loop servo control, with a speed fluctuation rate lower than ±1%, meeting the strict requirements in the standards for extremely slow needle insertion (such as 0.1mm/s).
The needle is made of high-strength tungsten steel and is equipped with a precise guiding sleeve structure, ensuring a high degree of verticality and extremely small deviation. Even when puncturing high-energy-density hard-shell batteries, it can do so stably and smoothly.
The system is compatible with a wide range of battery types including polymer, cylinder, square, module, and universal batteries, making it a versatile solution for various battery testing applications.
Yes. The standard model supports 5kN to 20kN. For higher-demand applications, the system can be customized to support 50kN, 100kN, 200kN, or 300kN, depending on your specific testing requirements.
The TA-JZ-LS-20kN complies with internationally recognized safety standards including UN 38.3, UL 2580, and IEC 62133, ensuring that testing procedures meet global regulatory requirements for battery safety evaluation.
