BES LITE is a cost-effective, low-profile, light-weight battery safety detector that uses Honeywell proprietary gas sensing technology to selectively detect battery electrolyte vapor, an indicator of thermal events. This provides an advanced warning of potential thermal runaway in Lithium-Ion battery packs.

BES LITE is designed to detect gases that are typically released during the initial phase of thermal runaway as well as throughout the entire thermal runaway process. This advanced detection capability facilitates the prompt identification of imminent dangers or risks, significantly enhancing safety measures in critical situations. Therefore, the sensor allows for proactive responses that can prevent loss of assets and protection of lives.

Early detection may vary based on factors such as the nature of cell abuse and its severity, state of charge, and other variables. BES LITE allows compliance with international regulations and guidance by providing a deterministic detection of thermal runaway events.

BES LITE is compatible with all lithium-ion battery chemistries and cell types, making it versatile for use in industrial lithium-ion battery packs. Engineered to support a ten-year lifespan, it aligns with the typical operational life of industrial equipment. As concerns over lithium-ion battery safety continue to rise, BES LITE stands out as the ideal battery safety detector, ensuring the protection of both personnel and assets.

Features:

  • Detects initial venting events before thermal runaway
  • Provides early warning of thermal runaway events
  • Selectively responds to electrolyte vapor
  • Intrinsically safe with no internal heating element
  • Inbuilt diagnostics functionality
  • Low-profile, compact design
  • Three-state analog output
  • Customizable to specific application needs
  • Compatible with all Lithium-ion battery chemistries and cell types
  • Ten-year sensor life
  • Resistant to common contaminants
  • Highly resistant to siloxane poisoning
  • Optimized for industrial applications

Applications:
Sealed and portable lithium-ion battery modules used in battery energy storage systems:

  • (BESS)
  • UAM/UAV
  • Micro-mobility
  • Medical devices
  • Light industrial goods

Value to Customers:

  • Enhanced asset protection:
    Battery electrolyte vapor detection enables early detection of thermal events, allowing enhanced asset protection
  • Selective detection:
    Detects only electrolyte vapor. The selective response and high sensitivity to electrolyte vapor allows for the mitigation of false alarms
  • Reliability in critical environments:
    Resistant to cross-gas interference & siloxane poisoning, ensuring reliable performance across demanding environments
  • Ease of installation:
    The low-profile construction & mounting flanges enable installation even in tight spaces. The three-state output simplifies integration
