Abstract:
A battery includes a folded bicell battery stack with an embedded fiber optic cable and sensor. A cell casing encloses the bicell stack with at least one fiber optic cable is embedded within the battery. The fiber optic cable includes an internal portion disposed within the cell casing and having at least one optical sensor disposed thereon. An external portion of the fiber optic cable protrudes from the casing. A sealing gasket is disposed at least partially around the fiber optic cable and between the cell sealing edges at a point of entry of the fiber optic cable into the battery.
