Abstract

A vehicle includes a high-voltage battery which has a housing and at least one battery module arranged in the housing that has multiple battery cells which are electrically connected together via a cell contacting system. Each of the battery cells has a battery cell housing with an emergency degassing opening which opens at a specified cell inner pressure and through which hot or burning gas can be leaked out of the interior of the battery cell housing into the housing of the high-voltage battery in the event of a disruption or damage to individual battery cells. The emergency degassing openings face the cell contacting system and/or a wall of the housing of the high-voltage battery. The cell contacting system and/or the wall of the housing of the high-voltage battery is/are provided with a heat protection layer, at least in the regions in which the emergency degassing openings are arranged.
