Panoramica
Distributor InventoryThe Battery Safety Electrolyte Sensor (BES) provides early and reliable detection of thermal runaway of lithium-ion batteries used in electric vehicles. Sensitive to electrolytes, the BES sensor detects thermal runaway at the crucial first vent stage, enabling prevention. This early detection capability of the sensor enables vehicles to meet international safety regulations such as UN GTR 20, China GB38031 & US NHTSA FMVSS 305A. The Battery Safety Electrolyte Sensor (BES) should be seamlessly integrated into the battery pack and capable of communicating with the Battery Management System (BMS) to help ensure that every journey is supported by reliable technology.FEATURES•Detects electrolytes released during the first vent (before thermal runaway) • Responsive to H2, CO released during thermal runaway • Patented alarm algorithm ensuring critical alerts are not missed • Resistant to siloxane poisoning • Automotive product with CAN 2.0B output with diagnostic features EARLY DETECTION OF THERMAL RUNAWAY FOR ELECTRIC VEHICLES• Electrolytes • Hydrogen • Carbon monoxide• Pressure (customizable) • TemperatureAPPLICATIONS • Lithium-ion battery packs used in electric and hybrid vehicles
