Lithium-ion fire & failure analysis
Energy Forensics Group delivers NFPA 921-compliant origin-and-cause analysis of lithium-ion failures — from e-bikes and power tools to grid-scale energy storage. Clear, thoroughly documented findings for counsel and carriers on both sides of a matter.
Start here
Almost everyone reaches us in one of three situations. Choose the one that fits, and we'll take you straight to what you need.
A fire just happened and physical evidence is at risk. Keep clear of the damaged battery, leave it in place, and get us involved before critical evidence is lost or altered.
Preserve the evidencePlain-English explainers for attorneys and adjusters — thermal runaway, how battery fires differ, and what drives liability across product categories.

Review credentialsWhy Energy Forensics Group
Most fire investigators come to batteries from the fire service. Energy Forensics Group comes to them from inside the technology: over a decade designing, building, and maintaining lithium-ion systems across North America.
That means a failure analysis grounded in how cells, packs, BMS electronics, and charging systems actually behave — why a cell vents, how thermal runaway propagates, and where design, manufacturing, or misuse truly sits in the chain of causation. The result is analysis built to the documentation standard litigation demands — starting from first principles, not pattern-matching.
