Apparatus for connecting in parallel a plurality of battery cells which are arranged parallel to one another with respect to a joining axis

Abstract

A device is described for connecting in parallel multiple battery cells (2) arranged in parallel to one another with respect to a joining axis using a contact plate (1) having individual passages (3). To enable a connection in parallel, which is reliable under periodic mechanical strains and nonetheless detachable, of individual battery cells (2) independently of their diameter and their relative location to the contact plate (1), wherein a simple assembling procedure can be maintained and a more flexibly designed serial interconnection of the battery cells can be enabled, it is proposed that each passage (3) is designed for the jacket-side enclosure of the battery cells (2) and comprises at least one contact tongue (4), which has on the passage side a contact body (5) protruding from the contact tongue (4) into the passage (3) in the form of a cut ovoid.

Dependencies are inferred from the claim text.
