Assuring Safety and Performance for the Energy Transition
Battery Energy Storage Systems (BESS) play a vital role in supporting renewable grids and stabilizing power supply. As energy density and deployment scale increase, so does the importance of verified safety, durability, and transport compliance.
BQCIS Battery & Storage Systems provides end-to-end testing services for lithium-ion, sodium-ion, and flow batteries. We validate cycle life, performance, abuse safety, and transport readiness in compliance with IEC 62619, UL 1973, UL 9540, and UN 38.3.
Our laboratories replicate real-world grid and mobility conditions to confirm safety, capacity retention, and environmental resilience—ensuring reliability from cell to megawatt-hour system level.
Key Testing & Verification Activities
Key Benefits of Battery Verification
Verified Safety Compliance
Ensures batteries meet IEC, UL, and UN safety criteria to prevent fires and thermal events during operation or transport.
Long-Term Performance Assurance
Cycle and capacity tests validate system longevity and provide data confidence for project investors and operators.
Operational Efficiency
Performance verification ensures batteries deliver reliable energy throughput across varied grid and climate conditions.
Global Transport Readiness
UN 38.3 compliance testing certifies batteries for international shipping by air, sea, or road—ensuring market access.
Success Story
Capacity Testing Validates Grid-Scale Battery Performance
A 50 MW BESS developer sought independent performance verification before commissioning. Investors required objective confirmation that actual energy throughput met the warranty guarantee.
BQCIS executed capacity verification using precision charge/discharge cycling under grid-simulated loads. Testing confirmed power delivery consistency and cycle efficiency while benchmarking against OEM specifications.
The system demonstrated 99% conformity to its rated performance, satisfying lender requirements and unlocking full project financing. The verified data provided confidence for long-term asset operation and warranty support.
