Detecting the first 2 stages of battery failures
Different phases of a li-ion fire

Stage 1
monitoring for environmental, mechanical, power & thermal abuse
to prevent failures and to maximize battery life span
React quickly and prevent catastrophic failures during the initial phase with our sensor platform. You'll have crucial minutes to hours to take action.

Our platform detects anomalies and helps you take preventive measures to avoid a thermal runaway and extend battery lifespan. It's a 2-in-1 solution designed specifically for this stage.

Our thermal, environmental, power, and mechanical sensors provide real-time data, enabling you to mitigate anomalies before they turn into (catastrophic) issues

Stage 2
gas release
first venting / offgas phase
This phase is when batteries release a gas before catastrophic failures. It is called stage 2.

When talking about li-ion batteries, in this phase you have a few seconds to a few minutes at most. You already have at least one or more batteries having a catastrophic failure. You are trying to limit the propagation of a thermal runaway. At InfraSensing we invented the daisy chained off-gas sensor. For overcharging and battery leakage we are looking for VOCs.

When using liquid cooling for your batteries, then you have also to consider a Hydrogen H2 sensor. Leaks in such systems can result in Hydrogen and thus require discrete H2 sensing. VOC sensors may not work with liquid cooling systems due to the limited time between the pressure relief vent opening in the battery pack and the fire. This can be as low as 2 seconds.

Using lead-acid batteries? In this phase it is H2 (hydrogen ) that is the target gas to detect.

The offgas sensors are available in select markets through OEM partners.
