Patent number: 11056742Abstract: A method for applying a rupture element to a housing part of a battery cell, more particularly to a housing part provided for sealing a battery cell, includes the following steps: providing the housing part, wherein the housing part has an inner side facing the interior of the battery cell and an outer side facing the exterior of the battery cell. A hole is provided in the housing part, through which in the event of a malfunction, in which pressure in the battery cell reaches an inadmissably high level, pressure can escape into the surrounding area. A plate-shaped rupture element is provided, which is at least slightly larger than the hole. The plate-shaped rupture element is applied to the hole from the outer side such that it fully covers the hole and an edge region of the plate-shaped rupture element is joined all around to an edge region of the housing part, which extends around the hole, such that the plate-shaped rupture element fluidically seals the hole.Type: GrantFiled: January 7, 2019Date of Patent: July 6, 2021Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Tobias Zeilinger, Ruediger Daub, Nikolaos Tsiouvaras, Juergen Herold, Christian Singer

Patent number: 10992012Abstract: A cell for an electrical energy store is provided, including a cell housing within which there is arranged an electrode and on the outer side of which there is arranged a terminal which is galvanically connected to the electrode, wherein an electrical securing element is connected in a current path between the terminal and the electrode for the purposes of galvanic separation of the electrode and of the terminal. The cell is characterized by having the securing element arranged outside the cell housing. In this way, it is possible in a simple manner for the state of charge of the cell to be checked, and also for the cell to be discharged, from the outside.Type: GrantFiled: September 21, 2018Date of Patent: April 27, 2021Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Rainer Stern, Stefan Roessler, Tobias Zeilinger
