Energy Storage System Safety
Underwriters Laboratories
Cell-level, module-level, and unit-level fire propagation testing. Every pack geometry we manufacture runs through a dedicated thermal runaway propagation test in our UL-certified test chamber.
Test Protocol
Thermal Runaway Propagation Test
Equipment
Forced-air calorimeter, 8-channel thermocouple array, high-speed IR camera (320fps)
Pass Result
No propagation beyond initiating cell in 47 consecutive pack configurations
Secondary Lithium Cells — Safety
International Electrotechnical Commission
Industrial application safety requirements covering overcharge, over-discharge, short circuit, crush, and thermal abuse. Our IEC 62619 protocol runs 100% sampling on every production lot, not a statistical subset.
Test Protocol
Overcharge / Short-Circuit / Crush Matrix
Equipment
Hydraulic crush fixture (0–200 kN), programmable charge/discharge cycler, blast-rated test enclosure
Pass Result
100% lot sampling · Zero field failures across 2.1M cells shipped FY2024
Lithium Battery Transport Testing
United Nations Recommendations
Eight-test sequence required for air, sea, and ground transport of lithium batteries. We maintain a dedicated UN 38.3 test lab on-site — clients receive full test summary documentation with every shipment.
Test Protocol
T1–T8 Transport Simulation Sequence
Equipment
Altitude simulation chamber, thermal cycling oven (−40°C to +75°C), vibration table (7–200 Hz)
Pass Result
Full T1–T8 documentation provided per lot · DGD-compliant shipping labels included
Quality Management System
International Organization for Standardization
Every production run operates under our ISO 9001-certified QMS. Lot traceability is maintained from cell receipt through pack serialization — each finished pack carries a laser-etched serial number linked to its full build record.
Test Protocol
QMS Audit + Pack-Level Traceability Verification
Equipment
Laser marking station (class-4 UV), MES traceability system, automated optical inspection (AOI) line
Pass Result
Recertified annually · Last audit score: 98/100 · Zero major non-conformances since 2021
Cell to Pack
How the Line
Actually Runs.
No black boxes. Here's the exact sequence from incoming cells to certified pack — every step with hard pass criteria.
Cell Sourcing & Incoming QC
We source prismatic, pouch, and cylindrical cells exclusively from Tier-1 manufacturers with verified chain-of-custody documentation. Every incoming lot undergoes capacity grading, internal resistance matching, and self-discharge screening before entering the line.
100%
Incoming lots screened
Module Assembly & Spot Welding
Automated spot welding stations apply nickel or aluminum busbars with ±0.05mm positional accuracy. Every weld joint undergoes inline pull-testing at 45N minimum — any weld below spec triggers immediate line stop and root-cause analysis.
45N
Minimum weld pull force
Thermal Runaway & BMS Integration
Battery management systems are calibrated and flashed on-line. Each pack runs a 4-hour formation cycle followed by thermal imaging at load — hotspots above 3°C delta trigger immediate quarantine. Cell-to-cell thermal runaway propagation barriers are installed per UL 9540A geometry.
3°C
Maximum thermal delta threshold
Pack Sealing & IP Certification
Enclosures are sealed in our positive-pressure clean room to IP67 or IP68 depending on application. Helium leak testing is performed on every sealed pack — pass criteria is less than 1×10⁻⁵ mbar·l/s. Final laser engraving links the pack serial to its full MES build record.
