Abstract:
Systems and corresponding methods for monitoring of a state of charge or a state of health of a battery are described. For example, the battery monitoring system may include strain gauges to measure dimensions or changes in dimension of cells of the battery, and may determine states of charge of the cells based on dimensional changes over time, e.g., based on data from strain gauges. The dimensional changes may also be corrected for dimensional changes due to thermal strain. In addition, states of health of individual cells of the battery may be determined by comparing the dimensional changes of each of the cells over time. Further, the data from strain gauges may be received at various frequencies, e.g., based on an expected operational duration of the battery and/or based on a current state of charge or state of health.

Claim (Index 1):
A battery monitoring system, comprising:\n a battery comprising a plurality of stacked cells; a housing configured to receive the battery; a retainer positioned around the plurality of stacked cells of the battery, the retainer configured to apply a target pressure to the plurality of stacked cells; a strain gauge positioned on a surface of the retainer; and a controller in communication with the strain gauge, the controller configured to at least:\n receive, from the strain gauge, data indicating a first electrical resistance associated with the strain gauge at a first time; \n determine a first dimension associated with the retainer based at least in part on the first electrical resistance associated with the strain gauge; \n determine a first dimension associated with the plurality of stacked cells corresponding to the first dimension associated with the retainer; \n receive, from the strain gauge, data indicating a second electrical resistance associated with the strain gauge at a second time; \n determine a second dimension associated with the retainer based at least in part on the second electrical resistance associated with the strain gauge; \n determine a second dimension associated with the plurality of stacked cells corresponding to the second dimension associated with the retainer; \n determine a change in dimension between the first dimension associated with the plurality of stacked cells and the second dimension associated with the plurality of stacked cells; and \n calculate a state of charge of the battery based at least in part on the change in dimension.
