Abstract
An electrochemical battery system in one embodiment includes a first electrode, a second electrode spaced apart from the first electrode, a separator positioned between the first electrode and the second electrode, an active material within the second electrode, a pressure sensor in fluid connection with the second electrode, a memory in which command instructions are stored, and a processor configured to execute the command instructions to obtain a pressure signal from the pressure sensor associated with the pressure within the second electrode, and to identify a state of charge of the electrochemical battery system based upon the pressure signal.
