SYSTEM AND METHOD FOR DIFFERENTIATING VENT CONDITION AND LEAKAGE CONDITION IN A BATTERY PACK

A system to differentiate between a vent condition and a leakage condition of electrolyte vapors released from a battery pack is disclosed. The system comprises a sensing element having a polymer support to detect a concentration of the electrolyte vapors, a heating element positioned and configured to heat the polymer support of the sensing element to evaporate electrolyte from the polymer support, at least one processor communicatively coupled with the sensing element and the heating element to activate and subsequently deactivate the heating element for an amount of time, determine the vent condition when the concentration of the electrolyte vapors exceeds a threshold level within a predefined time interval after the deactivation of the heating element, determine the leakage condition when the concentration of the electrolyte vapors does not exceed the threshold level within the predefined time interval.
