摘要： 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.

摘要： 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. Preferably, holes (25) are stamped into the bracket apex areas (23), along the contours of which holes (25) the brackets (19) are connected, in particular laser-welded, in a force-fitting or integral manner, to the cell pole end surfaces (26), once the mounting plate (16) has been fitted to the cells (12). For this purpose, the mounting plate (16) has aperture openings (27), which are in contrast larger, coaxially with respect to those holes (25).
