The burning question

Until thermal runaway is no longer a problem, early detection of failing battery cells will remain critical for active countermeasures that can literally save lives. To this end, US-based Amphenol has been working on its REDTR gas sensor platform, which can detect initial flammable gas venting from cell failures within lithium-ion battery enclosures. pv magazine sat down with Brian Engle, business development manager for the Amphenol Advanced Sensor Division, to dissect the technology and evaluate the safety improvement opportunities it offers.

What technology has Amphenol developed to deal with lithium-ion battery incidents? Our work involves early detection of thermal runaway. If we look at the conventional technology that’s been deployed to date, it monitors temperature, voltage, current on the cells, and tends to be a fairly late indicator of battery failure. Our Robust Early Detection of …
