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.

Vehicle with a high-voltage battery

A vehicle includes a high-voltage battery that has a housing and at least one battery cell arranged in the housing. The battery cell 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 pass 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 the battery cell. The emergency degassing opening faces a housing wall against which hot or burning gas flows in the event of the disruption or damage to the battery cell. The housing wall of the high-voltage battery is designed to be more thermally resistant locally in the region in which the emergency degassing opening is arranged and in which the hot or burning gas flows out of the battery cell housing in the event of a disruption or damage to the battery cell than in the wall regions at a distance from the emergency degassing opening.
