Battery cells for battery packs in electric vehicles

A method of providing battery cells for battery packs of electric vehicles, comprising:

• providing a housing having a first end, a second end, and an inner surface, the housing defining an inner region, the inner region disposed between the first and second ends;
• disposing an electrolyte in the inner region of the housing
• disposing a lid proximate to the first end of the housing;
• coupling the lid with the first end of the housing to seal the battery cell using a gasket;
• forming a recess and a groove on the inner surface, the groove forming a path from the recess to an egress point on the first end of the housing;
• and
• disposing a pressure sensor in the recess formed in the inner surface, the pressure sensor coupled with a pressure sensor wire disposed in the groove, the pressure sensor wire extending from the recess and past the egress point on the first end of the housing to provide sensed pressure information.

A method, comprising:

• providing a battery cell of a battery pack to power an electric vehicle, the battery cell comprising:
• a housing having a first end, a second end, and an inner surface, the housing defining an inner region, the inner region disposed between the first and second ends;
• an electrolyte disposed in the inner region of the housing
• a lid disposed proximate to the first end of the housing;
• a gasket that couples the lid with the first end of the housing to seal the battery cell;
• the inner surface having a recess and a groove formed therein, the groove forming a path from the recess to an egress point on the first end of the housing;
• and
• a pressure sensor disposed in the recess formed in the inner surface, the pressure sensor coupled with a pressure sensor wire disposed in the groove, the pressure sensor wire extending from the recess and past the egress point on the first end of the housing to provide sensed pressure information.
