Abstract
Provided herein are battery cells for battery packs in electric vehicles. The battery cell can include a housing having a first end, a second end, and an inner surface. The housing can define an inner region and an electrolyte can be disposed in the inner region of the housing. A gasket can couple a lid with the first end of the housing to seal the battery cell. The inner surface can include a recess and a groove. The groove can form a path from the recess to an egress point on the first end of the housing. A pressure sensor can be disposed in the recess. The pressure sensor can couple with a pressure sensor wire disposed in the groove and the pressure sensor wire can extend from the recess and past the egress point on the first end of the housing to provide sensed pressure information.
