Modernizing Traditional BESS Factory Acceptance Testing with Advanced Battery Diagnostics

White paper: Discover how improved BESS testing could prevent up to $2.3 billion in revenue and operational cost losses.

Learn about the key benefits of our BESSential 100% battery pack testing service over traditional Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) methods in our white paper “Modernizing Traditional BESS Factory Acceptance Testing with Advanced Battery Diagnostics”, created in collaboration with Sinovoltaics.

The white paper presents a case study of a 50 MWh energy storage project in Europe, where traditional FAT and SAT methods failed to detect severe thermal imbalances and voltage variations within the BESS. If left unresolved, the issues could have resulted in over $600,000 in financial losses due to accelerated battery degradation and system downtime. Since traditional quality assurance methods use sampling instead of testing every BESS container and battery pack, the financial cost could have been multiplied.
