FAQ
-
The equipment is specifically designed for battery destructive testing:
The inner liner is made of 304/316 corrosion-resistant stainless steel, which can be directly cleaned with a high-pressure water gun, making maintenance very convenient.
Modular Design for Wearable Parts: The needle assembly and heating plate are both of quick-change structure, making replacement easy.
Just clean up the combustion residue in time and check the sensor lines, and the equipment can undergo multiple repeated thermal runaway tests, eliminating the need for frequent factory repairs. -
The equipment adopts closed-loop control:
1. Displacement control: Servo motor drives the needle, with an accuracy of ±0.1mm
2. Temperature control compensation: PID constant temperature regulation, eliminating environmental errors -
The thermal runaway of the battery will produce toxic and corrosive smoke such as HF, CO, and hydrocarbons.
The equipment is equipped with a dedicated smoke treatment interface, which can be linked to the laboratory scrubber or purification system. After the test, it will automatically expel the air forcefully, and the exhaust gas will be filtered through multiple stages including activated carbon and alkaline washing, achieving compliance with emission standards and protecting the laboratory environment and personnel safety. -
The system supports a wide range of lithium-ion battery formats including cylindrical cells, prismatic cells, and pouch cells. The explosion-proof box is fully customizable in volume (1m³, 1.5m³, or 2m³) and steel plate thickness, allowing adaptation to different battery module and pack sizes. Custom fixture configurations are available upon request.
