Abstract
A high-voltage accumulator module having a multiplicity of battery cells arranged in a honeycombed parallel- and series connection assembly (for example, “honeycomb”). The gaps between the battery cells are filled with a thermally and electrically conductive potting compound. The battery cells are electrically insulated with respect to the potting compound. The potting compound is connected to an energy source via electrically conductive fixing elements that protrude into the potting compound and via two pole connections in such a way that a current flow through the potting compound which is as homogenous as possible is achieved. The two pole connections, for example, in the form of metal plates, may be fastened to the potting compound over a large surface area and in close electrical contact therewith by the fixing elements. The fixing elements may protrude as deep as possible into the potting compound in the form of strips or pins and may contain barbs.
