摘要： The present disclosure relates to a stacked cell manufacturing scheme for battery modules. A disclosed method of manufacturing a battery module includes assembling a plurality of prismatic battery cells of the battery module into a cell stack. The method includes compressing the cell stack using an actuating clamping mechanism, inserting the cell stack into a housing of the battery module with the actuating clamping mechanism engaged with and compressing the cell stack, and removing the actuating clamping mechanism from the cell stack. The housing of battery module maintains a compression of the cell stack above a predetermined threshold in the battery module after removing the actuating clamping mechanism.

摘要： 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.

摘要： A battery module includes a housing including a first interior surface, a second interior surface opposite the first interior surface, and a compressed cell assembly disposed within an interior space of the housing between the first and second interior surfaces. The compressed cell assembly includes a plurality of prismatic battery cells arranged in a cell stack that includes a first end, a second end opposite the first end, and a retaining wall disposed between the first end of the cell stack and the first interior surface of the housing. The retaining wall includes a first surface in contact with the first end of the cell stack and a second surface opposite the first surface that contacts the first interior surface of the housing. The first and second interior surfaces are configured to maintain the compressed cell assembly in a compressed state having a compression force above a predetermined threshold.
