1. Core Positioning​ A key safety monitoring component for new energy vehicle battery packs, installed inside the battery pack (next to cell modules). It real-time detects smoke and aerosols generated in the early stage of battery thermal runaway, transmits signals to the Battery Management System (BMS), and triggers early warning (indicator light/buzzer) or power-off protection to avoid fire risks. Compatible with all BEV and PHEV models.​ 2. Core Functions​ Accurate Detection: Recognizes characteristic smoke of battery thermal runaway (e.g., electrolyte decomposition gas aerosols), detection sensitivity ≤0.1mg/m³；​ Fast Response: Response time ＜100ms after smoke triggering, ensuring BMS starts protection measures in time；​ Environmental Resistance: Resistant to high and low temperatures (-40℃ to 85℃), IP6K9K protection rating, resistant to vibration (10-2000Hz) and electrolyte corrosion inside the battery pack；​ Fault Diagnosis: Generates fault codes (e.g., P1B00) when the sensor malfunctions, facilitating quick location and maintenance.​ 3. Core Advantages​ Early Warning: Captures thermal runaway precursors in advance, 3-5 minutes earlier than open flame detection, leaving sufficient time for safe disposal；​ High Reliability: No attenuation after 1000 high-low temperature cycle tests, service life ≥5 years/150,000km；​ Easy Integration: Provides CAN/LIN bus interface, directly adapting to mainstream BMS, replaceable with original sensors；​ Compliant & Safe: Certified to IATF16949 and ISO 14001, meeting GB 38031-2020 "Safety Requirements for Traction Batteries for Electric Vehicles".​ 4. Adaptability​ Vehicles: Covers BEV/PHEV passenger vehicles (sedans/SUVs), commercial vehicles (heavy-duty trucks/buses)；​ Battery Types: Adapts to ternary lithium batteries and lithium iron phosphate battery packs, supporting customization of different installation sizes.​ 5. Service Support​ Contact customer service for vehicle adaptation lists and installation drawings; free guidance on BMS communication protocol docking is provided.
