Quality Control Systems
Great Power enforces 100% inline inspection at electrode coating, assembly, formation, and PACK integration stages. Full traceability links raw material lots to shipped system serial numbers.
MES-Integrated Production
Real-time data capture on every workstation; SPC alerts trigger line-stop before tolerance drift.
Automated Optical Inspection
Vision systems inspect weld integrity, tab alignment, and electrolyte fill levels at high throughput.
Environmental Stress Screening
Thermal cycling, vibration, and humidity chambers validate PACK assemblies against IEC 62619 and UL 1973 protocols.
Cell-to-Pack Traceability
QR-coded lot tracking links each finished system back to its source cathode batch, separator roll, and formation cycle log.
R&D and Innovation
Great Power manufactures cell chemistry, pack architecture, and system integration in-house. The R&D program covers ion sponge technology, sodium-ion evaluation, and long-cycle LFP platforms.
Sodium-Ion Evaluation
Great Power was the first batch in China to pass sodium-ion battery evaluation by CETRI. Dedicated pilot lines test chemistries for stationary storage applications.
Cycle Life Validation
Cell cycle life exceeds 10,000 cycles under standard conditions. Wide temperature capability from -30°C to 60°C supports charging across diverse deployment scenarios.
