Abstract: A cell connector is provided by means of which an electrically conductive connection between a voltage tapping point and a voltage tapping line can be established, wherein the cell connector is for the connection of a first cell terminal of a first electro-chemical cell and a second cell terminal of a second electro-chemical cell and includes a voltage tapping point with a contact element for connection to a terminal element of a voltage tapping line and also a longitudinal axis and a peripheral wall extending about the longitudinal axis. The contact element includes a base material, which is at least partially pre-coated with a contacting material in an initial state, and reshaped from the initial state into a final state such that the proportion of the peripheral wall coated with the contacting material to the overall peripheral angular extent of the peripheral wall amounts to more than 50%.

Abstract: In order to enable the temperature in the region of at least one of the cell terminals that are connected to one another in an electrically conductive manner by a cell connector to be determined in a simple and reliable manner, there is proposed a cell connector for connecting a first cell terminal of a first electro-chemical cell and a second cell terminal of a second electro-chemical cell of an electro-chemical device in an electrically conductive manner which comprises a base body and a temperature sensing element that is fixed to the base body.

Abstract: A cell contacting system for an electro-chemical device which provides increased protection from damage and enables simple assembly of the electro-chemical device comprises a cover for an electro-chemical device which comprises a plurality of electro-chemical cells, wherein the cover comprises the following: a carrier element having at least one access opening which is associated with a functional element of the electro-chemical device; and at least one closure element which is held on the carrier element in such a way that the closure element is movable relative to the carrier element from a closed position, in which the closure element closes at least one access opening of the carrier element, into an open position in which the closure element exposes the at least one access opening of the carrier element so that the functional element associated with the access opening concerned is accessible from outside the electro-chemical device.
