Definitions

  • the invention relates to a housing for receiving an energy storage cell with a flexible shell.
  • Hybrid and electric vehicles require large amounts of electrical energy to operate an electric machine.
  • energy storage preferably nickel-metal hydride or lithium ion cells are used.
  • lithium ion cell design is in the form of a prismatic softpack.
  • the cell is enclosed by a flexible shell.
  • aluminum composite film is used as the material for the flexible shell.
  • the sheath is circumferentially welded around the area of the cathode, separator, anode layers and the inner Zellabieiter. At the inner cell arrester, the riveting of the outer metallic current conductor takes place.
  • the outer metallic current conductors are made of copper, for example.
  • Object of the present invention is to improve the rigidity of an energy storage cell with a flexible shell.
  • the housing for receiving the energy storage cell with a flexible shell is made of a material with respect to the shell of higher rigidity.
  • the material for the housing is preferably to use plastic. But it can also be used metal. In this case, ensure sufficient electrical insulation between the current conductors and the metal housing.
  • the housing has a window opening on one surface side. This ensures that the dynamically operating energy storage cell has the ability to "breathe” when placed in the housing. "Breathing” refers to volume increases and decreases in the interior of the energy storage cell and concomitant movements of the flexible envelope.
  • the housing has two openings through which the current conductors of the energy storage cell are derived. The electrical contacting of each current arrester takes place outside the housing.
  • the advantage of such a housing is the increased mechanical stability of a single energy storage cell.
  • the energy storage cell is in the housing as a pluggable module.
  • the arrangement of the energy storage cell in the housing it can be positioned as a compact unit and attached, for example, in an energy storage.
  • Several energy storage cells with housing can be arranged well next to each other or on each other. Forces acting on the current conductors are partially absorbed by the housing.
  • An existing plastic housing has the advantage that the current conductors are electrically isolated within the housing, and the advantage of weight savings over a metal housing.
  • a metal housing offers the advantage that it acts as a heat dissipator. The security of an energy storage cell with a flexible envelope is increased by the housing.
  • the housing comprises a heat dissipator in the form of a cooling plate.
  • a heat dissipator in the form of a cooling plate.
  • the heat sink Through the heat sink, the heat is dissipated from the energy storage cell.
  • the heat sink increases the rigidity of a plastic housing.
  • one surface side of the flexible shell of the energy storage cell can be adhesively bonded to the cooling plate by means of a thermally conductive adhesive bond.
  • the energy storage cell is glued to the bottom of the metal housing accordingly.
  • the connection of the energy storage cell to the cooling plate or to the metal housing can preferably take place via a double-sided adhesive heat-conducting foil.
  • the adhesive bond also increases the stability of the module energy storage cell and housing and ensures reliable positioning of the energy storage cell in the housing.
  • the current conductor of the energy storage cell in the region of the housing with an electrically insulating material potted.
  • Such materials are preferably technical waxes, potting resins or silicone.
  • this coating is designed as a seal crack resistant. The advantage lies in the direct electrical insulation of the current conductor.
  • the encapsulation also offers a significantly increased protection of the current collector from corrosion or oxidation.
  • the current conductors of the energy storage cell in the region of the housing for the purpose of electrical insulation of insulating caps are surrounded by a non-conductive material.
  • the current conductors of the energy storage cell are double insulated by insulating potting material and insulating caps in the region of the housing.
  • the insulating caps can be made of plastic. The advantage lies in the electrical insulation of the current conductors and a mechanical stiffening of the connection area between cell body and current conductor. The insulating caps contribute to the defined positioning of the energy storage cell in the housing.
  • electrically insulating plastic clips with a hinge and at least one snap hook are fastened to the current conductors in the region of the housing for the purpose of electrical insulation.
  • the current conductors of the energy storage cell are double insulated by insulating potting material and insulating plastic clips in the region of the housing.
  • the plastic clips comprise a hinge, preferably a film hinge. The plastic clips are clamped over the current collector and closed with snap hooks. The advantage lies in a complete electrical insulation of the electric current collector in the area of the housing. The connection area between cell body and current conductor is mechanically stiffened.
  • the plastic clips are preferably dimensioned so that they press the energy storage cell to the bottom of the housing when closing the housing and thus relieve an adhesive bond between energy storage cell and housing bottom or heat sink. Forces acting on the current conductors are partly absorbed by the housing and not exclusively by the adhesive bond.
  • the housing may, according to a preferred construction, consist of two parts: a bottom and a lid with the window opening. Bottom and lid are connected by a hinge and are closed by snap hooks.
  • the advantage is that the possibly electrically insulated energy storage cell can be inserted very quickly and cost-saving in the housing or glued to the floor.
