A recent report by Clean Energy Associates (CEA) reveals that 72% of manufacturing defects in battery energy storage systems (BESS) occur at the system level, marking a 24% increase from previous years. The report outlines that cell-level defects account for 15% and module-level defects for 13%. Among the system-level defects, a significant 62% fall under 'Safety-critical failures,' which include issues with fire detection and suppression, faulty auxiliary circuit panels, and thermal management defects. CEA emphasizes that critical failures pose severe safety risks and can lead to regulatory non-compliance.

CEA's findings indicate that 64% of system-level defects are related to the balance of system (BOS), often due to component defects or improper integration procedures. Additionally, 30% of defects are enclosure-related, while 6% pertain to performance tests. The report highlights the importance of fire safety, noting that 28% of inspected BESS units had fire suppression system defects. As the energy storage sector evolves, CEA's insights underscore the need for stringent quality control and safety measures to prevent potential hazards.
