Definitions

  • the invention relates to a battery module with at least one, preferably a plurality of battery cells, which are formed substantially plate-like and surrounded by a foam structure.
  • EP 0 631 338 A1 describes a battery having a battery housing, in which a plurality of battery cells are accommodated, wherein the battery housing is made of a plastic foam structure.
  • the foam structure in battery modules numerous demands are made.
  • its primary function namely to protect the battery cell or the battery module against mechanical damage, for example, have fire-retardant properties, be mechanically stable enough to accommodate installations such as cooling ducts, busbars, etc., a good heat balance and protection against current flashovers and short circuits offer, and much more.
  • the foam structure has at least two foam layers with the same or different mechanical, physical and / or chemical properties.
  • the application of several foam layers has the advantage that the layer thicknesses of the individual foam layers is lower, so that less heat is produced during foaming and thus can be dissipated more easily. Excessive heat input into the battery cells can damage them and is therefore undesirable.
  • the foam structure has a first foam layer which at least partially encloses at least one battery cell encloses, and preferably has fire-retardant properties.
  • This fire-retarding property can be achieved, for example, by replacing the blowing agent necessary for producing the foam structure during foaming of the battery cell by a fire-retardant gas or by an inert gas.
  • the foaming under a protective gas atmosphere prevents air pockets, which can have a fire-supporting effect in the event of a malfunction.
  • the first foam layer is designed such that it releases a protective gas or other fire-retardant substances in case of fire.
  • the at least one battery cell is here either partially foamed, wherein preferably the cell poles remain free to facilitate the contacting or are completely surrounded by this first foam layer.
  • a foam layer is provided as the second foam layer, which is designed as a load-bearing or structure-forming layer for different installations or components.
  • This second foam layer which usually also has a greater thickness than the first foam layer, is characterized in particular by its mechanical stability, which allows the inclusion of different internals.
  • internals for example, cooling lines, heat conducting plates, electrical lines, electrical and mechanical connecting elements, sensors and / or control elements can be arranged in this second foam layer.
  • this foam layer has a sufficient tracking resistance, so that foamed electrical components do not have to have their own insulation.
  • coolant leakage or Ventingkanäle be formed.
  • the structural stability of this layer also protects against damage to the cells or components during transport and installation in the vehicle and can absorb energy in the event of a crash.
  • At least one further, third foam layer is arranged between the first foam layer and the second foam layer. Since the heat generated during the foaming process depends on the layer thickness, that is to say on the mass of reacting material, it may be necessary to apply several thin layers of foam to the cell instead of one thick layer. Thus, the foam layer between the first and second foam layer serves an improved heat transfer, whereby the temperature at the battery cell kept as low as possible during the foaming process becomes . This situation can also be improved during the manufacturing process by a cooled foam mold.
  • an additional outer, fourth layer is connected, which serves the EMC protection, so that no electromagnetic energy can disturb the foamed control and / or sensors.
  • this foam layer is formed electrically conductive, for example, by incorporating conductive particles in the foam layer and / or conductive fabric and / or conductive coatings are applied to this layer.
  • this foam layer must have a suitable connection to the electrical ground.
  • an electrically conductive element for example in the form of a grid, mesh or the like, may also be embedded in the foam layer.
  • the foam structure according to the invention has a vapor barrier in a further embodiment of the invention.
  • This additional, or combined with the EMC protective layer layer has the task of protecting the underlying foam layers with the components therein, in particular against the effects of weather such as humidity.
  • the preparation of this layer is preferably carried out under a protective gas atmosphere, wherein air inclusions are particularly preferably avoided.
  • moisture-repellent layers such as films, lacquers, and / or nano-coatings are applied.
  • the at least two foam layers are arranged separable from each other around the at least one battery cell. Due to the separability of the at least two foam layers from one another, in particular when recycling the battery module according to the invention or when exchanging defective components, a simpler separation of the individual components can take place.
  • This separability is, for example, designed such that the at least one first foam layer has an at least partially structured surface that is complementary to an at least partially structured surface of the adjacent second foam layer.
  • These structured surfaces can be designed here in particular as toothings.
  • separating means between two adjacent foam layers but also between the components and the foam layers may be arranged, which are applied during the Einfumvorganges and facilitate a later division of the individual foam layers.
  • separation aids such as wires, straps or ropes are incorporated into the foam structure. By pulling on these separation aids the foam structure is divided and allows removal of individual areas of the foamed battery module. Likewise, markings may be provided at locations where mechanical separation of the foam structure is safely possible. Likewise, it can be provided that at least one foam layer of the foam structure has at least one predetermined breaking point.

It may be necessary to apply a plurality of thin layers of the same or a different foam in order to realize the lowest possible heat input into the battery cell 100 during foaming.
