Abstract: A device for electrical interconnection of cells of a battery pack through cell connectors, and a battery pack having the device and the cell connectors are provided. A plurality of cell connectors for connection of at least two cell poles are fitted on a mounting plate, electrically isolated from one another. Each cell connector has at least one flexible bracket which extends away from a connection area. The flexible brackets are coupled to the connection area through a resilient structure having a meandering shape.

Abstract: A foundation structure of an offshore plant, such as a wind turbine, comprising at least one foundation element that can be anchored to the seabed without a gravity foundation and without a floating foundation and a support structure fastened thereto for fixing the offshore plant. The foundation element is a pile that can be inserted into the seabed by means of drilling and/or by means of vibratory driving, can be fixed in the seabed by means of an organic and/or inorganic material, and is oriented at an angle from a vertical on the seabed. A method of installing the foundation structure on a seabed includes first anchoring the coupling element by means of piles inserted into the seabed and then connecting the support structure to the coupling element.

Abstract: A connection system (1) for an energy storage device (2), wherein the energy storage device (2) comprises a plurality of cells (3), with a plurality of cell connectors (4) for electrical interconnection of the cells (3), with a storage control unit (15) for monitoring an energy supply and/or charging condition of the cells (3), with a plurality of control lines (17) for transmitting electrical signals between the cell connectors (4) and the storage control unit (15), wherein at least one of the cell connectors (4) and at least one control line (17) associated with said cell connector (4) are manufactured as a transmission element (5), jointly from a semi-finished product (6).

Abstract: A device for electrical interconnection of cells (12) of a battery pack (11) by means of cell connectors (15) and a battery pack (11) having such cell connectors (15) are distinguished as being convenient for assembly and functionally reliable in that at least one mounting plate (16), which can be latched on the battery pack (11) in a mounting frame (17), is fitted with cell connectors (15) which are electrically isolated from one another, on the basis of the geometric requirement of cell poles (13) to be interconnected to one another, which cell connectors (15) each have flexible brackets (19) for their apex areas (23) to make elastic contact with the end surfaces (26) of cell poles (13). The brackets (19), which are supported by one flank in the form of a flexible spring on the mounting plate (16), are part of a stamped grid, which also comprises conductor tracks (32) which are integrally connected thereto, for example for connection of a battery management means.

Abstract: The invention relates to a copper-tin alloy, comprising 0.2 to 0.8% by weight Sn, 0.1 to 0.6% by weight Ni and/or Co, 0 to 0.05% by weight Zn, 0 to 0.2% by weight Fe, 0.008 to 0.05% by weight P, and also Cu as remainder.
