Battery cells for battery packs in electric vehicles

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

• providing a housing defining an inner region that houses an electrolyte;
• providing a lid;
• coupling the lid with the housing to seal the battery cell using a gasket, the gasket including an inner portion having an ingress point and an egress point,
• disposing a thermocouple wire within the inner portion such that the thermocouple wire extends through the inner portion, past the ingress point and past the egress point, the thermocouple wire including a first lead having a first length, a second lead having a second length, and a third lead having a third length, the second length greater than the first length, the third length greater than the second length;
• disposing each of the first lead, the second lead and the third lead within a common jacket between the ingress point and the egress point of the gasket;
• disposing a thermocouple sensor in the inner region;
• and
• coupling the thermocouple sensor with the first lead, the second lead and the third lead of the thermocouple wire to provide sensed temperature information through the thermocouple wire.
