Honeywell has developed a new Battery Safety Electrolyte Detector (BES LITE) specifically targeting sealed portable lithium-ion battery packs. The detector is designed for non-automotive applications that require a cost-effective, low-profile, small-footprint battery safety sensor for various uses such as battery energy storage systems, unmanned aerial vehicles, electric two-wheelers, and portable battery applications.
The primary cause of fires in lithium-ion batteries is thermal runaway, a self-accelerating cycle in which the battery’s temperature increases, leading to fires and explosions. Factors like overcharging and internal short circuits can cause the battery separator to melt, initiating heat generation. As the temperature rises, the electrolyte vaporizes and releases hazardous vapors. BES LITE utilizes Honeywell’s gas sensing technology to selectively detect battery electrolyte vapor, providing an early warning of potential thermal runaway.
BES LITE is designed to detect gases released during the initial phase of thermal runaway as well as throughout the entire process, ensuring comprehensive monitoring. The detector is specifically engineered to be highly resistant to siloxane poisoning and only responds to battery electrolyte vapors, offering early and reliable detection without false alarms. This makes it an ideal safety sensor for critical applications where the detection of battery electrolyte vapors is crucial to prevent potential disasters.
The sensor’s ability to selectively detect battery electrolyte vapors enables it to provide advanced warning of thermal runaway incidents, allowing for timely intervention to prevent fires and explosions. Its reliable and early detection capabilities make BES LITE a valuable tool for enhancing battery safety in various applications where lithium-ion batteries are used, ensuring safer and more reliable performance.
Honeywell’s BES LITE electrolyte detector offers an effective solution for detecting battery electrolyte vapors and providing advance warning of potential thermal runaway. Its selective gas sensing technology, resistance to siloxane poisoning, and reliability in detecting electrolyte vapors without false alarms make it an ideal safety sensor for critical applications like battery energy storage systems, unmanned aerial vehicles, and portable battery applications. By detecting hazardous gases released during thermal runaway, BES LITE helps prevent battery fires and explosions, ensuring the safety and reliability of lithium-ion battery packs in various applications.
In conclusion, Honeywell’s Battery Safety Electrolyte Detector (BES LITE) is a new and innovative solution for detecting battery electrolyte vapors and providing early warning of thermal runaway in sealed portable lithium-ion battery packs. With its advanced gas sensing technology, resistance to siloxane poisoning, and reliable detection capabilities, BES LITE is designed to enhance battery safety in critical applications where the detection of electrolyte vapors is essential to prevent fires and explosions. By offering selective detection and avoiding false alarms, BES LITE ensures early intervention to mitigate potential hazards and improve the overall safety and performance of lithium-ion battery packs.
