Lithium-Ion Battery Venting: Early Detection for Improved Safety
Understanding and mitigating lithium-ion battery venting is critical for ensuring safety and reliability in electric vehicles (EVs) and energy storage systems (ESS). Venting events don’t just release gas — they create plasma, arc flash risk, and potential thermal events.

Gain deep insight into the physics of lithium-ion battery venting, the dangers of battery off-gassing, and how early gas detection can prevent catastrophic failure.
What you’ll learn:
- How venting releases flammable gases (H₂, CO, VOCs) far above explosive limits
- The physics of plasma ejection, particulate discharge, and ignition
- Why ionized gases invalidate IEC 60664 insulation standards post-vent
- The role of battery gas sensor technology in detecting failures within seconds
- Design strategies to isolate high-voltage components and direct gas flows
- Validation testing that proves sensor placement inside the pack airspace has minimal impact on detection speed

Why Lithium-Ion Battery Venting Demands a Smarter Safety Strategy
Cell venting detection is no longer a “nice-to-have” — it’s a must-have. When a lithium-ion cell vents, temperatures can exceed 1000°C and plasma can conduct across gaps once considered safe. These events have triggered arc flashes, busbar vaporization, and gas explosions in real-world tests.
The presentation outlines:
- Why voltage and pressure sensors often miss the earliest signs of failure
- How early detection of battery failure using gas sensors provides up to 2 minutes of lead time
- The dangers of vented auto battery gas mixing with HV systems, creating arc discharge potential
- Sensor data that supports regulatory and design decisions
What You’ll Gain from This PresentationAn in-depth understanding of lithium-ion battery venting and detection is crucial for engineers, safety professionals, and system designers. This presentation delves into:
