Definitions

  • the present invention relates to a vehicle with a high-voltage battery according to the preamble of patent claim 1.
  • High-voltage storage of electric or hybrid vehicles such as B.
  • the vehicle “BMW i3” have a high-voltage storage case with several so-called “cell modules” arranged in it.
  • Each of the cell modules consists of several battery cells arranged in a row one behind the other, which are electrically interconnected.
  • the housing in which the individual battery cells are arranged in the BMW i3 is a relatively stiff aluminum housing that "upwards", i.e. towards the passenger compartment, is closed by a screwed-on cover.
  • the individual battery cells of the BMW i3 each have an essentially cuboid battery cell housing.
  • the battery cell housing is liquid and gas tight, i. H. nothing can escape from the inside of the battery cell housing.
  • battery cell housings usually have an emergency degassing opening, which, for. B. as A predetermined breaking point can be formed, which opens when a predetermined internal cell pressure is exceeded and allows gas to escape from the inside of the battery cell to the outside. In extreme cases, such as B.
  • the escaping gas can ignite in very unfavorable constellations, with an escape into the environment or into the passenger compartment of the vehicle being prevented with a high degree of certainty that the battery cells are additionally enclosed by the housing of the flute voltage storage device.
  • the object of the invention is to create a vehicle with a flap voltage storage device which, in comparison with vehicles with conventional flap voltage storage devices, offers even greater safety with regard to possible fire hazards.
  • the starting point of the invention is the consideration that, in the event of extreme mechanical damage to individual battery cells and / or short circuits inside the cell, very hot, burning gas should be able to escape from the interior of individual battery cells into the interior of the battery voltage storage housing via the emergency degassing openings of the battery cell housing.
  • the basic principle of the invention is to make the flock voltage storage housing locally thermally more resistant at least in those areas in which the emergency degassing openings of the battery cells are arranged.
  • the entire flochvolts storage housing, z. B. by choosing an appropriately fire-resistant material, such as. B. steel, and sufficiently high wall thicknesses can be made fire-resistant overall.
  • the invention aims to reinforce the housing of the high-voltage battery (only) in those areas that are particularly thermally highly thermally stressed in an extreme case, ie in a so-called “thermal event”.
  • the starting point of the invention is a vehicle with a high-voltage battery, which has a housing and at least one battery cell arranged in the housing.
  • a battery cell of course, several or a plurality of battery cells can of course be arranged in the housing, which can be interconnected “in packets” to form “cell modules”.
  • the at least one battery cell arranged in the housing of the high-voltage battery has an emergency degassing opening that opens from a predetermined internal cell pressure, through which hot or burning gas can escape from the interior of the battery cell housing into the housing of the high-voltage battery in the event of a fault or damage to the battery cell.
  • the emergency degassing opening of the battery cell housing faces a wall of the housing of the high-voltage battery, against which hot or burning gas flows (immediately) in the event of a fault or damage to the battery cell.
  • the essence of the invention is that the wall of the high-voltage battery in the area in which the emergency degassing opening is arranged and hot or burning gas flows out of the battery cell housing in the event of a fault or damage to the battery cell is made locally more thermally resistant. than in regions of the wall spaced apart from it.
  • the wall of the housing of the high-voltage battery is therefore only locally thermally reinforced or designed to be more thermally resistant.
  • “local” means in that area or areas in which hot or burning gas emerging from the interior of the battery cell housing (s) strikes the wall of the housing of the high-voltage battery, similar to the case with a burning gas jet from a welding torch.
  • the wall of the housing of the high-voltage battery can be z. B. consist of aluminum or an aluminum sheet, which is locally thermally resistant in the area in which the at least one emergency degassing opening is arranged and hot or burning gas flows out of the battery cell housing in the event of a fault or damage to the battery cell.
  • the wall of the housing of the high-voltage battery can also consist entirely or at least in some areas of a plastic material (or a fiber-reinforced plastic material), which in the area in which the at least one emergency degassing opening is arranged and in the event of a fault or damage to the battery cell hot or burning gas flows out of the battery cell housing, is locally thermally more resistant.
  • the emergency degassing z. B be formed by a predetermined breaking point provided in the battery cell housing, which only opens or is “pressed open” or blown open when a predetermined pressure in the interior of the battery cell housing is exceeded.
  • the entire housing of the high-voltage battery can be provided with an additional thermally resistant layer.
  • One idea of the invention is that the wall of the high-voltage battery in the region of the at least one emergency degassing opening has at least one thermally resistant layer has more, ie at least one additional thermally resistant layer, than in regions of the wall spaced apart therefrom.
  • the one thermally resistant layer or the several thermally resistant layers which locally thermally reinforce or reinforce the wall of the high-voltage storage housing, has or have a total layer thickness of at least 0.1 mm.
  • thermally resistant means that a lacquer layer is used which is thermally resistant at least up to a predetermined minimum temperature of, for example, 1000 ° C. or 1100 ° C. or 1200 ° C. or 1300 ° C.
  • An activation of the paint by the heat of the emergency degassing can be used as a positive effect.
  • the paint does not have to be burned in when it is applied to the housing (especially with ceramic paints), but is only painted.
  • the lacquer layer can therefore be an intumescent layer (“insulation layer former”). Intumescent materials increase in volume and density when exposed to heat. It can be provided that the layer “chars” under the influence of heat, expands and thus has a heat-insulating effect.

  • the wall of the housing of the high-voltage battery is designed to be more thermally resistant on its side facing the emergency degassing opening, ie on an inside of the housing, than in regions of the wall spaced apart therefrom.
  • the “local thermal reinforcement” is therefore preferably on the inside of the wall of the High voltage storage attached.
