Control Issues And Integration Challenges Dominate Safety Incidents Rather than Direct Cell Failures INCIDENTS BY TRIGGERING COMPONENT
ROOT CAUSES OF INCIDENTS
BOS Balance of System
Control issues are triggering many incidents: While only 11% of incidents were directly attributed to cell failures, many more were indirectly caused by cell failures triggered through operation conditions outside of predefined safety windows due to control issues
Issues happen early in the project lifecycle: In about 3 out of 4 cases, events happen during construction, commissioning or within the first 2 years of operation
Integration remains challenging: Integration related issues are the most common root cause of incidents including wiring, coolant systems or safety systems
