PROTECTIVE UNIT FOR A BATTERY MODULE OF A HIGH-VOLTAGE BATTERY, BATTERY MODULE, AND HIGH-VOLTAGE BATTERY
The invention relates to a protective unit (15) for a battery module (1) of a high-voltage battery of a motor vehicle for electrically insulating cell housings (7) of prismatic battery cells (3) of the battery module (1), which battery cells are stacked to form a cell stack (2), and a cell-contacting system (12) of the battery module (1), which cell-contacting system interconnects the battery cells (3) by electrically connecting cell terminals (8, 9) of the battery cells (3), the protective unit comprising pre-formed intermediate layer (16) made of an electrically insulating material, which intermediate layer can be applied to a side (11) of the cell stack (2) having the cell terminals (8, 9) and therefore can be arranged between the side (11) of the cell stack (2) having the cell terminals (8, 9) and the cell-contacting system (12) and which intermediate layer has a number of cut-outs (17) which corresponds to the number of cells terminals (8, 9), said cut-outs being provided for the feeding through of the cell terminals (8, 9) when the intermediate layer (16) is applied to the cell stack (2). The invention further relates to a battery module (1) and to a high-voltage battery.
