Abstract: A method for connecting cell outgoing conductors of a first and a second cell. Here, a connection between the first and second cell outgoing conductors is produced by means of a connecting apparatus, which includes a first and a second component. At the same time, however, the first and second components also have the function of pre-bending the cell outgoing conductor of the first and second cells, respectively, in order thus to enable a particularly low physical height of the cell outgoing conductor arrangement. A system according to the invention includes a first and a second cell, which have cell outgoing conductors that are connected and shaped in this way.

Abstract: A battery includes a plurality of flat cells which are electrically connected in parallel and/or in series with one another and which, when disposed next to one another in rows perpendicular to their flat sides, form a substantially prismatic configuration. In order to obtain more accurate information about the state of the individual flat cells during operation of the battery and, for example, to allow such information to be used for matched temperature management, a heat dissipation plate, which is thermally linked to at least one flat side of a plurality of the flat cells and in each of which at least one temperature sensor is integrated, is provided in each case in the configuration. The battery may be used for spatially resolved battery temperature measurement.
