Abstract: The present invention relates to a pressure relief element (11) to be used as an overpressure safety means in devices where a gaseous medium must be rapidly released in case of overpressure, wherein the pressure relief element (11) has at least one notch (9) which is designed as a predetermined breaking point where the pressure relief element (11) breaks at a certain level of overpressure, thereby irreversibly opening an exhaust path for the gaseous medium. The present invention also relates to a pressure relief device of an electrochemical battery, comprising such a pressure relief element and a battery comprising such a pressure relief device.

Abstract: The present disclosure relates to a battery module that includes a housing having a first opening configured to receive one or more battery cells and an electrical component, a housing cover configured to be disposed over the first opening to enclose the one or more battery cells and the electrical component in the housing, a signal connector disposed within the housing and electrically coupled to the electrical component, where the signal connector is configured to be actuated from a first position to a second position, and a vent port in alignment with the signal connector such that the signal connector is accessible to a push device passing through the vent port to facilitate directing the signal connector into the second position and toward a second opening of the housing cover when the housing cover is disposed over the first opening.
