Can battery thermal runaway be predicted and prevented?
Recent incidents involving e-bike batteries and EV recalls highlight the challenge of managing thermal runaway in confined spaces. How do you integrate gas detection and thermal imaging into your facility's strategy to mitigate these risks?

A short editor's note to get this one going.
The e-bike and EV recall stories in the radar this week have one thing in common: the first warning is usually gas, not heat or smoke. When a lithium-ion cell starts to vent, electrolyte vapour, hydrogen and carbon monoxide can appear well before the cell reaches thermal runaway. A thermal camera sees the problem once the cell is already hot; an off-gas sensor may see it earlier.
The questions we would like to hear real answers to:
- In charging rooms and battery stores, are you combining off-gas detection with thermal imaging, or relying on one of them?
- Where do you place the sensors in a small, crowded room where airflow changes all the time?
- What action does the first alarm trigger: ventilation, power isolation, or just a notification?
