Patent number: 9806322Abstract: The invention relates to a battery cell connector with a first and a second substantially flat limb (1, 2), wherein the first limb (1) has a connecting side (3) for connection to a plurality of electrodes of a battery, the second limb (2) is arranged at an angle with respect to the first limb (1) and extends from that side (4) of the first limb which is opposite the connection side (3), wherein a shoulder (5) is provided which extends from the first to the second limb. Against this background, the invention specifies a battery cell connector with a high current-carrying capacity which is improved in comparison with the known battery cell connectors. For this purpose, the invention provides that the profile of the height (h) of the shoulder (5) from the first limb (1) towards the second limb is nonlinear and is convex with respect to the first and the second limb (1, 2).Type: GrantFiled: March 24, 2010Date of Patent: October 31, 2017Assignee: Johnson Controls Autobatterie GmbH & Co. KGAAInventors: Ingo Koch, Peter Streuer, Andreas Dudenbostel, Anja Schwarze, Dirk Stellfeldt, Peter Schellenberg
