Patent ID: 10573864

Abstract:
Provided herein are battery cells for battery packs in electric vehicles. The battery cell includes a housing defining an inner region, an electrolyte disposed within the inner region, and a gasket that couples a lid with the housing to seal the battery cell. The gasket can include an inner portion having an ingress point and an egress point. The inner portion can have disposed therein a thermocouple wire that extends through the inner portion, past the ingress point and past the egress point. The thermocouple wire can include a first lead, a second lead, and a third lead. The first, second, and third leads can be disposed within a common jacket between the ingress point and the egress point. A thermocouple sensor can be disposed in the inner region and be coupled with the first, second, and third leads of the thermocouple wire to provide sensed temperature information.
