🚨 NFPA 855 / IEEE 1679 (Float Current mA/Ah Creep, Thermal Runaway Detection <24h)

BMS Thermal Runaway Early Warning Calculator

Detect insidious thermal runaway conditions in stationary VRLA and lithium battery cabinets under NFPA 855 & IEEE 1679: monitor float charging current creep (>10 mA per 100 Ah capacity increase during constant float) combined with cell temperature differentials (>3 deg C), trigger automated charger disconnects 24 hours before venting, and BMS safety margins.
