Battery Safety Aerosol Sensors CAN Communication Output
DESCRIPTION
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. CUSTOMIZATION The BAS Series may be customized to better meet application needs. Solutions may be tailored to exact specifications for improved time to market, lower total system costs and enhanced reliability. For technical assistance, we provide global engineering and service support for your needs.
FEATURES
- High accuracy and low temperature drift
- CAN communication protocol
- Wake-up output and request input for high reliability system integration
- Aerosol threshold value of 5000 µg/m³ allows early detection of thermal runaway events VALUE TO CUSTOMERS
- Early detection of thermal runaway has the potential to mitigate the loss of life and property
- The ECO mode enables continuous system monitoring in low power mode
- Thermal runaway detection sensor allows compliance with international regulations and recommendations
- Solutions may be tailored to exact specifications for improved time to market
- Lower total system cost and enhanced reliability 006003 Issue 1 OPERATING MODES The sensor function in the following operating modes:
- ECO Mode: The sensor operates in ECO Mode when the request pin voltage is set to low. The sensor wakes up for 200 ms and hibernates for the remaining 12000 ms (typical) to reduce power consumption during each measurement cycle of 12200 ms (default value). In ECO Mode, CAN communication is disabled. If the sensor detects an aerosol concentration above the set threshold, a wake-up signal is sent to the BMS (Battery Management System) to initiate a full battery system check.
- Continuous Mode: The sensor operates in Continuous Mode when the request pin voltage is set to high by the BMS. CAN communication is enabled in Continuous Mode. In Continuous Mode, the sensor monitors and outputs the aerosol concentration to the BMS using CAN communication. The sensor may be switched to ECO Mode by setting the request pin voltage to low. NOTE: The sensor default working mode is ECO mode. WORKING LOGIC FUNCTIONS
- Request Signal: The BMS controls the sensor’s operating mode through the request pin of the sensor.
- Wake-up Signal: When the sensor detects that the aerosol concentration is above the threshold, the wake-up pin is set to high to wake up the BMS. TRANSPORTATION
