INLINE BATTERY ELECTROLYTE LEAK DETECTION

Abstract

A system configured to detect leakage of an electrolyte from a battery cell. The system includes: a probe configured to contact the battery cell and create an air-tight connection between the probe and the battery cell over a fill port of the battery cell that has been closed with a seal; a pump in fluid communication with the probe, the pump configured to draw a vacuum through the probe; a housing defining a chamber including a window, the probe extends from the housing, the pump is connected to the housing to draw the vacuum through the probe into the chamber; and a sensor configured to detect presence of the electrolyte within the chamber pulled from the battery cell through the seal of the fill port by the vacuum generated by the pump, presence of the electrolyte within the chamber is indicative of the seal of the fill port of the battery cell being compromised.
