BATTERY SAFETY SENSORS
Honeywell battery safety sensors enable the early detection of thermal runaway to mitigate the loss of life and property within electric vehicles and non-electric vehicle applications Battery Energy Storage Systems, 2w and 3w vehicles, electric lawnmowers, medical devices, and campsite battery generators. BES & BES LITE sensors specifically detect battery electrolyte vapor that typically is released during the “First Vent” event of a lithium-ion cell and throughout the thermal runaway process.

LITHIUM-ION BATTERY SENSORS SOLUTIONS
Our sensing solution are designed both for Lithium-ion battery packs in electric and hybrid vehicles as well as Lithium-ion battery modules in battery energy storage systems (BESS), micro-mobility lithium-ion battery packs including two and three wheeled vehicles and portable and mobile lithium-ion battery packs including electric lawn mowers, medical devices, campsite battery generators.
BES Series - EV Sensor Solution
The Battery Electrolyte Sensor (BES) provides early and reliable detection of thermal runaway of lithium-ion batteries used in electric vehicles. Sensitive to battery electrolyte vapor, the BES sensor detects thermal runaway at the crucial first vent stage, enabling prevention. This early detection capability of the sensor enables vehicle to meet international safety regulations such as UN GTR 20, China GB38031 & US NHTSA FMVSS 305A.
- 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
- Automotive product with CAN 2.0B output with diagnostic features
BES LITE Series - Non-EV Sensor Solution
The BES LITE, available in flange-mount and board-mount versions, detects battery electrolyte vapor that is typically released during the “First Vent” event of a lithium-ion cell and throughout the thermal runaway process. This event has been observed to occur 5 to 15 minutes prior to single cell thermal runaway. Detecting thermal runaway early can help mitigate the loss of life, property, and assets when the right countermeasures are implemented.
- Detects initial venting events before thermal runaway
- Provides early warning of thermal runaway events
- Selectively responds to electrolyte vapor
- Low-profile, compact design
- Three-state analog output
BAS Series - EV Sensor Solution
The BAS Series uses light scattering principle to detect particulate matter in battery packs of electric vehicles and energy storage systems (ESS).
- Detects particulate matter such as smoke, drops of liquid, dirt in Lithium-ion battery packs
- Very early detection of thermal runaway event allows the mitigation of loss of life and property
- Two operating modes allows battery monitoring in low power mode
- EV compliance with international regulations and recommendations
- CAN communication allows easy system integration
BPS Series - EV Sensors Solution
The BPS Series uses a combination of MEMS (Micro- Electromechanical System) and ASIC (Application-Specific Integrated Circuit) to detect pressure changes in the battery packs of electric vehicles and energy storage systems (ESS).
- Early detection of thermal runaway event allows the mitigation of loss of life and property
- Settable warning threshold for customization to fit end application operating conditions
- Two operating modes allows battery monitoring in low power mode
- Compliance with international regulations and recommendations for thermal runaway detection
- CAN communication allows easy system integration
