Abstract
Apparatuses and methods for determining one or more performance related characteristics (such as state of charge and/or health) of one or more electrochemical cells that store and release electrical energy are disclosed. Embodiments include pressure and/or temperature sensors that sense a change in pressure resulting from the tendency of the electrochemical cell to change volume and/or the temperature of the one or more electrochemical cells as the electrochemical cell(s) are charged or discharged. Alternate embodiments include one or more calculating members that receive pressure and/or temperature information from the pressure and/or temperature sensing members and calculate a performance related characteristic of the electrochemical cell. Still further embodiments include determining one or more performance related characteristics of an electrochemical cell by sensing the tendency of an electrochemical cell to change volume (such as by sensing pressure) and/or by sensing the temperature as the electrochemical cell is charged or discharged.
