Honeywell BES 24V - An extension of the Honeywell Battery Safety Sensor Portfolio
First Vent Detection | Rate of Change Algorithm | Automotive Grade | 12V & 24V Options

Honeywell has released its 24V Battery Safety Electrolyte Sensor (BES), an extension of the previously launched BES Series. This product extension enables the seamless integration of the BES Series into high‑voltage battery packs that operate on 24V. The Honeywell battery safety sensor portfolio is designed to enhance safety in lithium‑ion, on‑road, and stationary battery applications.

The Battery Safety Electrolyte Sensor (BES) is an automotive-grade sensor designed for early detection of venting and thermal runaway in battery systems. Utilizing an advanced and patented rate of change algorithm, the BES detects battery electrolyte vapor commonly released during the initial venting phase called First Vent, as well as hydrogen and carbon monoxide gases released during a thermal runaway event.

The ability to detect the First Vent provides an essential early warning for potential thermal runaway incidents in Lithium-Ion battery packs. This proactive early detection facilitates timely and appropriate mitigation measures, significantly reducing the risk of thermal runaway. BES employs a patented advanced rate of change algorithm designed to identify significant changes in the concentration of target gases within a sealed battery pack. This innovative method effectively reduces the occurrence of false negatives that may be seen with conventional ppm-based sensors, which focus on precise target gas threshold monitoring. The algorithm is tuned to prevent false positives, improving the end-user experience. Furthermore, the algorithm is supported by more than 12 years of rigorous research and validated through seven years of practical field deployment.

This extensive experience not only enhances the reliability of the detection algorithm but also underscores its effectiveness in real-world applications. BES enhances the safety and reliability of automotive battery systems.

Sensing:

• Battery electrolytes
• Hydrogen
• Carbon monoxide
• Humidity (customizable upon request)
• Pressure (customizable upon request)
• Temperature

Features:

• Responsive to battery electrolyte vapor released during the first vent (before thermal runaway)
• Responsive to hydrogen and carbon monoxide released during thermal runaway
• 12V and 24V supply voltage options
• Patented rate of change algorithm to mitigate false negatives
• Resistant to siloxane poisoning
• Compatible with all Lithium-ion battery chemistries and cell types
• Automotive product with CAN 2.0B output with diagnostic features
• Tested for performance life of 15 years

Applications:
Sealed lithium-ion battery packs or modules used in

• Electric Vehicles
• Hybrid Vehicles
• Other On-Road Applications

Value to Customers:

• Enhanced Asset Protection:
  Battery electrolyte vapor monitoring provides early warning of thermal events, enabling thermal
  runaway prevention and asset preservation
• Reliable Battery Health Monitoring:
  BES responds to multiple gases that are typically released during thermal runaway, therefore
  increasing detection reliability and reduces false negatives
• Ease of Integration:
  The rate of change algorithm eliminates the need for precise target gas threshold testing and
  validation. As a result, it significantly reduces integration costs and timeline
