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.
