Thermal runaway in lithium-ion batteries is a critical concern for safety in electric vehicles. To mitigate the risk of thermal runaway in lithium-ion batteries, it is crucial to proactively implement comprehensive monitoring solution to provide early warning as preventive step against potential harm from lithium-ion battery thermal runaway incidents. As mandated by UN GTR 20 and GB 38031:2020, it is imperative to provide warning signals in advance, allowing passengers sufficient time (5 minutes) to evacuate from the dangerous EVs.
Concerning the safety risks of thermal runaway events and regulatory requirement of 5-minute early warning, gas detection technology can be an effective way to provide timely warning for thermal runaway events in compliance with regulatory requirement. Normally, at the early stage of thermal runaway events, a significant number of hazardous gases, encompassing substances such as carbon dioxide (CO2), carbon monoxide (CO) and hydrogen gas (H2), may release from lithium-ion batteries. Gas detection solutions can provide timely warning by monitoring those gases released during the early stage of thermal runaway events, enabling prompt intervention, evacuation, and containment measures, to minimize damage and ensure safety.
With 20-year accumulation on gas detection technology, Cubic, a manufacturer of high-quality gas sensors and gas analyzers, has leveraged its mature gas sensing technology platforms based on NDIR technology and MEMS thermal conductivity technology, and developed diverse gas sensors for automotive industry. Specially for Li-battery thermal runaway gas leakage detection, Cubic developed the latest gas sensor solutions, ATRS-1016 and ATRS-1012, with the advantages of high accuracy, fast response and long-term stability.
Cubic ATRS-1016 series is a MEMS thermal conductivity Hydrogen sensor that can effectively monitor H2 leakage and generate an early warning signal to formulate safety alarm strategies. With the features of fast response time, long life time and low power consumption, ATRS-1016 series MEMS TC H2 sensor can be widely used for applications of Li-battery thermal runaway, hydrogen fuel cell and hydrogen energy storage.
Cubic ATRS-1012 sensor is a Li-battery thermal runaway detection sensor that can effectively monitor CO2 and H2 released from lithium-ion batteries, and generate an early warning signal to Battery Management System (BMS), to formulate safety alarm strategies. Cubic innovatively combines non-dispersive infrared (NDIR) and thermal conductivity (TC) technology to integrate a sensor solution that has remarkable characteristics such as fast response time, accurate measurement, long life time and low power consumption, could be widely used for Li-battery electrical vehicle and energy storge system.
With features of rapid response and high reliability, Cubic ATRS-1016 and ATRS-1012 could be helpful to preemptively address potential Li-battery safety risks in EVs. Cubic ATRS-1016 and ATRS-1012 sensors represent the forefront of gas detection technology in the field of thermal runaway events and underscore Cubic’s capability to enhancing safety in the automotive industry. With long-term dedication in R&D, Cubic will continuously improve the accuracy, efficiency, and reliability of gas sensors to meet the dynamic demands of the automotive industry, fostering safer driving environments and empowering the automotive industry.
