Ensure safe, reliable, and high-quality energy storage systems from day zero.
Detect and resolve potential issues early with rigorous Factory Acceptance Testing protocols, detailed audits, and expert validation to protect your investments and operations.
A single faulty battery cell, a loose busbar, or a mis-tuned BMS can tip an entire plant from profit to problem. Thermal runaways, capacity fade, and uneven ageing lurk behind the spreadsheets. Only end-to-end, data-rich QA—covering cells, racks, electronics, and communication—guards both safety and investor returns long after the factory shine has worn off.
Quality assurance services we offer.
Factory Acceptance Testing planning and execution
We design and oversee Factory Acceptance Tests (FAT) to validate product quality and compliance before equipment leaves the factory. Our team coordinates test schedules and protocols tailored to specific project needs, ensuring no stone is left unturned.
Problem identification and resolution
During FAT execution, we actively supervise and participate in procedures, identifying and resolving non-conformities in collaboration with engineering and manufacturing teams. This ensures prompt corrective actions and maintains high quality standards.
Reporting and approval
ACCURE consolidates all test data—including deviations, root cause analyses, and corrective actions—into structured reports. We then present findings to internal stakeholders and external clients, securing formal approval for product shipment and installation.
Non-conforming cells caught before shipment.
Challenge
A European BESS developer asked ACCURE to verify a shipment of prismatic LFP cells against a strict quality plan before delivery.
ACCURE insights
Within a few hours, ACCURE’s cloud-based FAT benchmarked the factory data against the contractual specification and flagged two major non-conformities:
Capacity consistency – the total spread was 1.7 % (limit ≤ 1 %), with only 57 % of cells meeting the requirement.
DCIR omission – the supplier did not measure direct-current internal resistance at all, leaving a critical safety and performance metric unverified.
Alternating-current resistance (ACIR) was the only parameter both measured according to the test plan and found to be in spec.
Outcome
The lot was rejected prior to shipment, avoiding downstream risk and giving the developer leverage to secure a fully compliant replacement batch.
ACCURE’s independent experts guide you through the entire battery journey—from procurement to day-to-day operation and beyond.
