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: The present invention refers to a high-voltage battery for power supply, particularly of an automotive vehicle, comprising: an energy storage module with a plurality of electrochemical storage cells and a wall accommodating the plurality of storage cells, each storage cell comprising at least two electric connection terminals, and an upper part for contacting and covering the connection terminals, said upper part overlapping the wall in a contactless manner, so that a gap remains relative to the storage cells.

Abstract: The present invention relates to a cell contacting arrangement for an energy storage module having a plurality of electrochemical storage cells, each storage cell having at least two electric connection terminals, the arrangement comprising: a carrier plate which is mountable on the energy storage module, and at least one cell connector inserted into the carrier plate for connecting at least two of the connection terminals of different storage cells, the carrier plate comprising at least one catch spring having a detent for fixing the cell connector in the carrier plate.

Abstract: In order that even the cell connectors (17) of, for instance, a traction rechargeable battery (11) which carry very high currents can be connected to a battery management system (21) in a fault-resistant and functionally reliable manner, firstly a circuit board (24) in the form of a leadframe (25) encapsulated with plastic by injection molding is latched onto the housing (13) mechanically grouping the cells (12), said circuit board in any case not projecting higher than the adjacent end faces (15) of the cell terminal connections (14) projecting at a clear radial distance therefrom.

Abstract: The present invention refers to a current tap element for an energy storage module, comprising: a contact element made from a first metal for directly connecting to a pole of the energy storage module, a conductor element which is directly connected to the contact element and is made from a second metal differing from the first metal, an overmolded plastic covering which completely encloses the conductor element, and a connection in the plastic covering for contacting the conductor element.

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.
