    Abstract: A battery system includes an electrochemical cell. The electrochemical cell includes a cover having an opening therein. The electrochemical cell also includes an aluminum terminal pad disposed proximate an outer surface of the cover, and having a pad opening aligned with the opening in the cover. The pad opening includes a tapered surface such that the pad opening has a larger cross-sectional width proximate an upper surface of the aluminum terminal pad than proximate a lower surface of the aluminum terminal pad opposite the upper surface and facing the outer surface of the cover. The electrochemical cell also includes a rivet having a body portion extending through the opening in the cover, a head portion disposed in the pad opening of the aluminum terminal pad, and a shoulder extending between the body portion and the head portion. The head portion includes an inverted cone shape corresponding with the tapered surface of the pad opening and having a maximum cross-sectional width greater than a minimum cross-sectional width of the pad opening.

    Abstract: The present disclosure includes a battery module having a plurality of battery cells disposed in a housing. Each of the plurality of battery cells has a positive terminal, a negative terminal, an overcharge protection assembly, and a casing having an electrically conductive material. The overcharge protection assembly includes a vent, a first spring component, a second spring component, and an insulative component. The first spring component is coupled to the positive terminal, the second spring component is coupled to the negative terminal, the insulative component is between the first spring component and a conductive piece and between the second spring component and the conductive piece, and the vent is configured to drive the insulative component from between the first and second spring components and the conductive piece, such that the first and second spring components contact the conductive piece, when a pressure in the casing exceeds a threshold.

    Abstract: A battery module includes a battery module housing, a heat exchanger including a plurality of fins disposed in the housing, a first lithium ion battery cell and a second lithium ion battery cell disposed within the battery module housing. The first lithium ion battery cell and the second lithium ion battery cell are separated by a fin of the plurality of fins. The module includes a temperature sensing component coupled to the fin separating the first and second battery cells. Filler material is disposed within the housing and between the battery cells and the fins to mechanically restrain the battery cells within the battery module housing. The filler materials conduct thermal energy between the battery cells and the fin. The filler material covers a free end of the fin and the temperature sensing component. The temperature sensing component is coupled to a conductor extending out of the filler material.

    Abstract: The present disclosure includes a lithium-ion battery module that has a housing and a plurality of lithium-ion battery cells disposed in the housing. Each of the plurality of lithium-ion battery cells includes a first terminal with a first polarity, a second terminal with a second polarity opposite to the first polarity, an overcharge protection assembly, and a casing electrically coupled to the first terminal such that the casing has the first polarity, the casing having an electrically conductive material. The lithium-ion battery module includes a vent of the overcharge protection assembly electrically coupled to the casing and a conductive component of the overcharge protection assembly electrically coupled to the second terminal. The vent is configured to contact the conductive component to cause a short circuit and to vent a gas from the casing into the housing when a pressure in the casing reaches a threshold value.
