New Energy · Energy Storage & Photovoltaics – CATL (Contemporary Amperex Technology Co., Ltd.)

Products: 6m³ large thermal shock chambers, 41 three-zone explosion-proof constant temperature & humidity chambers
Testing applications:

Cell high-temperature aging screening: 45°C~60°C for 7–14 days to eliminate early failures.
High/low temperature cycling: -40°C to +85°C per GB/T 31486, >500 cycles to verify capacity retention and internal resistance.
Damp heat aging: 85°C/85%RH for 1,000 hours to evaluate sealing and electrolyte stability.
Thermal stability: 5°C/min ramp to 130°C to monitor thermal runaway onset temperature for safety thresholds.
Efficiency & data value: The 41-chamber deployment increased daily cell testing capacity to over 5,000 units, cutting test cycle time by 30%. All units connect to CATL’s industrial internet platform for real-time cloud data integration with batch genealogy, material formulas, and BMS data. Analysis helped optimize NCM811 and LFP cell formulations, boosting cycle life by more than 15%.
