Product features

Innovative combined gas generation analysis to support mechanism research: The self-thermal release detection sensitivity is much higher than the standard detection threshold of 0.02℃/min, with excellent insulation performance. Innovative integrated insulation thermal runaway-gas generation combined test. It can be equipped with a camera for real-time monitoring and recording of gas generation behavior, providing key evidence for studying the gas generation mechanism of the battery cell.

"Material - Battery Cell" full-chain thermal safety assessment: The cavity size is 200mm * 250mm, covering all types of battery cells in the small-scale test stage. The modular design enables it to conduct both battery material thermal stability tests and battery cell tests, achieving cross-scale assessment of thermal safety data from materials to battery cells.

Experimental efficiency increased by 5 times, facilitating efficient research and development: Equipped with innovative heating wire-assisted heating technology, combined with baseline calibration and intelligent algorithms, the experimental efficiency can be maximally increased by 5 times, helping researchers quickly eliminate high-risk formulations and improving research efficiency.

Compact and flexible, widely applicable: The body is compact, no complex site modification is required, and it can be quickly put into use. It can be flexibly adapted to different scenarios such as university laboratories, enterprise R&D centers, battery factory design departments, etc.

Sealing design, multiple protections: The sealing structure design complies with GB/150 standards, with a pressure capacity of up to 3MPa. It can conduct puncture experiments in a completely sealed state, accurately evaluating the safety risks of the battery in extreme conditions. It is also equipped with safety systems such as rupture discs, pressure relief valves, sound and light alarms, electrical emergency stop buttons, abnormal detection of furnace cover position installation, and dual over-temperature detection, providing comprehensive protection for personnel and equipment safety.

Professional thermal analysis software, easy to operate and efficient: Precisely analyzes thermodynamic/dynamic parameters, specific heat capacity, charging and discharging heat generation, and data such as GB/T 36276 insulation temperature rise. It has a built-in temperature difference baseline database and supports online calibration of thermocouples consistency. Pressure/temperature-video synchronous monitoring, with the entire experimental process being visible.
