SPONSORED CONTENT The Inside Story on Preventing Lithium-ion Battery Fires with Enhanced Jelly Roll Insulation Testing T he continuous increase in energy demand and for improved performance are stimulating the rapid maturation of lithium-ion batteries in large, energy-intensive applications such as electric vehicles (EVs) and various renewable energy storage systems (ESS). However, the rapid increase in battery usage, energy density and high-speed charging and discharging comes with a rise in fire and explosion incidents. SAE's Automotive Engineering discussed the typical causes of EV battery fires with Anthony Lu, Chroma ATE Inc. product manager, and how the enhanced capabilities of the company's Battery Cell Insulation Tester can help to reduce the potential for battery cell insulation-related fires. Why is it difficult to analyze the cause of most lithium-ion battery fires? Most fire-involved accidents with lithium-ion batteries are initiated by severe inflammation and it is difficult to analyze the actual cause. Common reports cite electrical control system errors or the lithium metal deposition compilinghttp://info.hotims.com/84495-714
