NDIR Automotive Li-battery Thermal Runaway Sensor PM CO2 CO HC H2

Introduction

ATRS-1020 sensors can effectively monitor CO2, CO/HC/H2 and particulate matters released before the thermal runaway trigger of lithium-ion batteries, as well as temperature and pressure, and transmit the measurement signal via CAN communication to battery management system (BMS), to formulate safer early warning strategies. Cubic has mastered a variety of gas sensing and detection technologies. In view of the performance requirements of sensors for thermal runaway monitoring, such as fast response time, accurate measurement, less cross interference, long service life and low power consumption, Cubic innovatively combines non-dispersive infrared (NDIR) spectroscopy and MEMS metal oxide semiconductor technology (MOX), an integrated sensor solution integrating a variety of core sensor technologies is introduced, which can effectively and accurately measure combustible gas.
