Abstract

A protective unit is provided for a battery module of a high-voltage battery of a motor vehicle for electrically insulating cell housings of prismatic battery cells of the battery module, which battery cells are stacked to form a cell stack. A cell-contacting system of the battery module interconnects the battery cells by electrically connecting cell terminals of the battery cells. The protective unit includes a pre-formed intermediate layer made of an electrically insulating material, which intermediate layer can be applied to a side of the cell stack having the cell terminals and can be arranged between the side of the cell stack having the cell terminals and the cell-contacting system. The intermediate layer has a number of cut-outs which corresponds to the number of cells terminals. The cut-outs are provided for the feeding through of the cell terminals when the intermediate layer is applied to the cell stack.
