Daren T. Slee

Daren T. Slee, P.E., CFEI

Senior Managing Consultant

Mr. Slee specializes in electrical engineering issues involving electrical failure analysis, preproduction circuit safety and functional analysis and testing, electrical reliability analysis, arc flash explosion investigation, utility power and transformer failure analyses, electrocution investigations, as well as printed circuit board and electrical component failure analysis, and the electrical root cause of fires.

Mr. Slee is a well-known expert in battery failure analysis and a contributor to Linden’s Handbook of Batteries, Fourth Edition, Appendix H: Methodologies for Battery Failure Analysis. He has performed many failure analyses of lithium-ion batteries, as well as failure analyses and general analyses of batteries of other chemistries concerning nickel metal hydride, lead acid batteries, Zinc-Air, and Vanadium-Redox.

Mr. Slee's experience includes printed circuit board failure analysis specifically as a result of their insulating materials. He is familiar with the many possible root causes of insulating material failures, from degradation due to long-term heating or humidity, conductive anodic filament formation, and electrical component failure. He also has experience in failure analysis of other electrical insulating systems that lead to overheating.

Mr. Slee has expertise in testing electronic systems for safety and functionality. He has performed many investigations focused on reliability and is very familiar with the tools of reliability engineering including failure modes and effects analysis (FMEA), mean time between failure (MTBF) calculations, single (and double) points of failure (SPOF) analysis, and parts derating evaluation.
