KGD-ATRS-210 Battery Thermal Runaway Monitoring Sensor with NDIR CO₂ and MEMS MOX CO Fast Response (T90 < 15s)

The Battery Thermal Runaway Monitoring Sensor KGD-ATRS-210 can effectively monitor indicators such as CO₂ + CO, temperature and pressure released before the triggering of battery thermal runaway, and transmit the measurement signals to the BMS through CAN communication. This solution has remarkable features such as accurate measurement, fast response time, low cross-interference, low power consumption and long service life.

• For the measurement of CO₂, the non-dispersive infrared (NDIR) absorption spectroscopy technology is adopted.
• The accuracy can reach ± (50ppm + 5% of the reading) within the measurement range of 0-10000ppm; the response time is fast with T90 < 15s, there is no gas cross-interference, the ultra-low power consumption mode can reach the μA level, and the service life can be up to 15 years.
• For the measurement of CO, an independently designed MEMS production line is used to produce metal oxide semiconductor (MOX) sensors. The electronic nose technology is adopted to screen sensors with good selectivity for CO gas, little influence from temperature and humidity, and stable detection signals. At the same time, it can be expanded to detect a variety of other gases according to the thermal runaway research results of the manufacturer; the service life of the semiconductor CO sensor exceeds 15 years, and it has corrosion resistance to silicone gases.
• The MEMS MOX sensor for CO measurement has little influence from temperature and humidity, stable detection signals, and can be expanded to detect a variety of gases; its service life exceeds 15 years, and it has good corrosion resistance to silicone gases.
• The module adopts a mature automotive-grade circuit design, which can adapt to harsh in-vehicle environments.
• It has real-time CAN communication, and the protection level can reach IP65.
