Honeywell BAS Series for EV Battery Safety

The BAS Series are automotive-grade aerosol sensors that use the principle of light scattering to detect and report thermal runaway events in lithium-ion battery packs. It detects the presence and concentration of aerosols such as smoke, liquid and debris that are early indicators of a thermal runaway event in an enclosed lithium-ion battery pack. The BAS Series measures and reports aerosol concentration from 200 μg/m³ to 10000 μg/m³ using CAN (Controller Area Network) communication protocol. They have a factory-programmed, thermal runaway warning threshold of 5000 μg/m³. These products are designed to meet higher quality and reliability requirements. The BAS series is RoHS compliant.
