Test conditions

  • LFP cell, 3.2 V / 25 Ah
  • Overcharged at 0.5C until first venting
  • 20 L enclosed test box, 25 ± 5 °C ambient

WHAT HAPPENS NEXT

Turn the alarm into action.

BSM3

Detects hydrogen

GPIO alarm

Your BMS can:

  • Notify operators
  • Stop charging or disconnect power
  • Activate ventilation
  • Trigger fire suppression (if fitted)

BSM3 provides the alarm. Your BMS determines the response.
