Abstract
A battery module with integrated pressure measurement. The battery module may include a plurality of battery cells configured for storing and supplying electrical power, a housing module including a base configured for supporting the battery cells and a plurality of walls configured for providing a restraining pressure on the battery cells, an assembly including a central cover covering the battery cells, a strain gauge circuit configured for sensing a deformation of the central cover resulting from the central cover expanding and contracting with the battery cells, and a cell monitoring unit (CMU) configured for generating a pressure measurement based on the deformation.

A battery module with integrated pressure measurement, comprising:
- a plurality of battery cells stacked in a side-by-side facing relation, the battery cells configured for storing and supplying electrical power such that the battery cells periodically expand and contract sideways when storing and supplying the electrical power;
- a housing module including a base and opposed sidewalls configured for restraining the battery cells in the side-by-side facing relation, the base configured for supporting the battery cells and the opposed sidewalls configured for providing a sideways pressure on the battery cells;
- an integrated interconnect board (ICB) assembly configured for electrically interconnecting the battery cells, the ICB assembly including a central cover extending end-to-end between opposed ends of the battery cells, the central cover configured for expanding and contracting sideways with the battery cells;
- a strain gauge circuit configured for measuring a sideways deformation of the central cover resulting from the central cover expanding and contracting sideways with the battery cells;
- and
- a cell monitoring unit (CMU) configured for generating a pressure measurement of the sideways pressure based on the sideways deformation.
