Czujniki gazu BESL-20200-000

  • BESL-20200-000
  • Output -20 °C ... 70 °C
  • Connector Analog tri-state
  • Operating voltage 5 VDC
  • Working temperature Samtec connector (TSW-101-06-T-S)
BES Lite – Battery Safety Sensor (Board Mounted Version)

BES Lite is a compact gas sensor designed for early detection of hazards in lithium-ion batteries. It reacts to the presence of electrolytic gases – ethyl methyl carbonate (EMC), dimethyl methyl carbonate (DMC), diethyl methyl carbonate (DEC), ethylene (EC), and propylene (PC) – at a very early stage, before temperature increases, fire, or explosions occur.


Key Features:
  • Early detection of electrolytic gases (thermal runaway)
  • Analog tri-state output
  • No heating element – ​​safe operation
  • Resistance to contaminants and siloxanes
  • Design optimized for PCB mounting (board mount)

Advantages:
  • Reacts at an early stage of gas release, enabling preventive action
  • Minimizes the risk of false alarms – high Selectivity
  • Works with various cell types
  • Lower energy consumption and ATEX compliance
  • Sensor lifespan: up to 10 years

STEPS LEADING TO THERMAL DEFECTS

Abuse

A situation of abuse (electrical, thermal, or physical) leads to internal short circuits, which causes internal heating.

Electrolyte pressure

The electrolyte solution between the anode and cathode evaporates under the influence of increasing heat. The pressure inside the cell begins to rise.

SENSOR ACTIVATION
Gas Release

The increasing pressure inside the cell bursts the cell's vent, releasing electrolytic gases.

Increase Temperature

Internal reactions cause the cell temperature to exceed a critical point, beyond which the cell temperature increases uncontrollably.

Fire and Explosion

The temperature increase causes uncontrolled combustion of the battery cell and the possibility of an explosion.
