Battery Thermal Management Innovation
xEV Conference and Expo

May 11, 2023 | Crown Plaza | Palo Alto, California

We’ll be featuring solutions for battery management system (BMS) thermal runaway detection based on a MEMS hydrogen sensor that detects hydrogen concentrations in the air by measuring the change in thermal conductivity of the gas mixture inside the BMS compartment.

Hydrogen detection is the state of the art for triggering battery failure alarms in electric vehicles (EVs) since hydrogen sensors react faster than pressure sensors to short circuit conditions and battery cell overcharge. Posifa Technologies makes this gold standard more affordable, reliable, and space-efficient with sensors built on our highly repeatable, high-volume CMOS MEMS technology.
