September 12, 2024: Sinovoltaics, in collaboration with Volytica Diagnostics, has released a white paper claiming that enhanced testing and diagnostics can prevent significant financial losses and optimize system performance for Battery Energy Storage System (BESS) projects.

The white paper, “Modernizing Traditional BESS Factory Acceptance Testing with Advanced Battery Diagnostics” details the advantages of their BESSential 100% battery pack testing service over traditional Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) methods.

The white paper presents a case study of a 50MWh 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, the paper claims.

“Since traditional quality assurance methods use sampling instead of testing every BESS container and battery pack, the financial cost could have been multiplied,” it argues.

“The BESSential service, which includes 100% battery pack analytics, identified critical defects at the factory, ensuring that a defect-free BESS was delivered to the client, avoiding project completion delays and future revenue losses.

“When similar defects are projected across the estimated global deployments through 2030, BESS project developers could collectively incur $2.3 billion in preventable revenue and O&M losses through 2030.
