Definitions

  • the present invention relates to an energy storage unit for storing electrical energy comprising a plurality of stacked flat cells, each having protruding electrodes.
  • Energy storage units comprising a stack of flat cells (so-called prismatic cells or pouch cells) are used, for example, in electrically driven motor vehicles. Due to the high voltages and current intensities occurring during operation, considerable heat amounts can develop which have to be dissipated in order to avoid overheating of the energy storage unit. However, the cooling devices used conventionally for heat dissipation are expensive and require relatively much construction space, which especially in the field of automobile engineering is very limited.
  • an energy storage unit comprising at least one cooling body which is heat-conductively connected, at least in sections, to the flat cells, wherein the cooling body at least partially consists of a plastic material and has openings through which the electrodes extend.
  • the cooling body can dissipate heat losses arising in the flat cells and thus increases the reliability and the service life of the energy storage unit.
  • a configuration made of a plastic material enables simple and inexpensive manufacturing and is, on top of that, advantageous with regard to saving weight.
  • the openings can particularly be slots adapted to the electrode shape and size. Due to the openings it is possible to arrange the cooling body on the electrode side of the flat cells, wherein the cooling body is placed as near as possible to the active cell region, thereby enabling especially efficient cooling. Since the electrodes are led through the openings, it is additionally possible to realize a cooling body arrangement which is especially space-saving.
  • a one-piece cooling body can be provided or a plurality of cooling bodies can be combined to form a cooling body arrangement.
  • the cooling body at least partially consists of an electrically insulating material.
  • the cooling body is capable of fulfilling the function of electrical insulation in addition to heat dissipation. Thereby corresponding separate insulating elements can be omitted, thereby saving costs as well as construction space.
  • the energy storage unit can comprise a connection unit connecting the flat cells at least electrically, wherein the cooling body is heat-conductively connected, at least in sections, to the connection unit.
  • a connection unit commonly comprises elements for interconnecting the individual flat cells serially and/or in parallel.
  • the connection unit can comprise various interconnection elements and contact elements for electrically contacting the flat cells and for tapping electrical power.
  • these electrical interconnection and contact elements generate Joule's heat (especially in the case of high-voltage connections), resulting in heating-up of the components of the connection unit. Due to the heat-conductive contact between the connection unit and the cooling body, this heat can be reliably dissipated.
  • the cooling body can be arranged between the flat cells and the connection unit.
  • the energy storage unit thus has a sandwich-like structure, wherein the flat cells, the cooling body and the connection unit are stacked one on top of the other.
  • This structure is enabled due to the fact that the electrodes are led through the openings of the cooling body.
  • the cooling body is capable of taking up and dissipating heat losses radiating from the flat cells as well as arising in the connection unit, i.e., for example, in strip conductors, contacts or interconnection elements, whereby the service life of the energy storage unit is increased. Due to the fact that the cooling body is arranged between the stack of flat cells and the connection unit, i.e. integrated in the energy storage unit, it is possible to configure heat dissipation in a way which saves especially much construction space. Another advantage results from the fact that the cooling body can be used for increasing the mechanical stability of the energy storage unit.
  • connection unit and/or the cooling body are embodied in a plate-like shape and extend in a plane which is perpendicular to the respective extension plane of the flat cells.
  • connection unit and the cooling body can be arranged at an end face of the stack of flat cells and cover the stack of flat cells. This in particular facilitates the heat-conducting connection of the cooling body to all the flat cells of the stack.
  • connection unit and the cooling body can, at least in sections, with their surfaces abut on one another in order to guarantee in this way efficient heat transfer between the two components.
  • the cooling body is embodied as a carrier element for the connection unit and/or for a cover element of the energy storage unit.
  • the cooling body fulfils an advantageous additional function by increasing the mechanical stability of the overall arrangement.
  • the cooling body can comprise fixing elements for fixing the connection unit and/or a cover element of the energy storage unit in order to especially facilitate assembly.
  • connection unit too, can have openings, particularly slots, which are in alignment with the openings of the cooling body and through which the electrodes extend, wherein the electrodes are connected to the connection unit especially at the side of the connection unit facing away from the flat cells.
  • the openings can be encircled by insulating material.
  • insulation sleeves can be introduced in the openings. Such a measure can be omitted in the area of the cooling body if the cooling body itself is made of a non-conducting material.
  • Cooling elements can be arranged between the flat cells, which cooling elements are heat-conductively connected to the flat cells and the cooling body. Thereby more efficient cooling of the flat cells is achieved.
  • the cooling elements can be configured in a plate-like shape, wherein one of the plate-shaped cooling elements is arranged between each pair of adjacent flat cells.
  • the plate-shaped cooling elements can, over their entire surface, abut on the respective adjacent flat cells in order to ensure uniform and effective heat dissipation.
  • the flat cells can be glued to the cooling elements.
  • a heat-conducting adhesive can be used for this.
  • the cooling elements are inserted in recesses of the cooling body and in particular glued to the cooling body. In this way, assembly is facilitated and at the same time the mechanical stability of the overall system is increased since the cooling elements form a coherent entity with the cooling body.
  • each of the cooling elements can have at least one depression, in particular extending essentially in parallel to the extension plane of the cooling body.
  • the depression can be a protrusion having a C-shaped or an S-shaped cross section and extending over the whole length of the cooling element.
  • At least one hollow space which is formed in the cooling body and through which a coolant is able to flow, is assigned to each of the cooling elements, wherein the hollow space in particular extends in parallel to the flat cells.
  • a separately fed hollow space can be assigned to each of the cooling elements or the individual hollow spaces can be interconnected such that eventually a continuous overall hollow space, which has, for example, a meandering shape, is obtained for the corresponding energy storage unit.
  • the respective hollow space can also be formed by the fact that the cooling body has a depression or a recess covered in a fluid-tight manner by the connection unit.
  • the hollow space can have a U-shaped cross section having two leg portions directed towards the assigned cooling element, wherein the cooling element extends in the area between the leg portions.
  • the hollow space, through which a coolant can flow, thus encompasses one end of the associated cooling element and in this way enables especially efficient heat dissipation therefrom.
  • a plurality of hollow spaces can be assigned to each of the cooling elements.
  • the energy storage unit has at least one coolant duct for supplying the hollow spaces with coolant, wherein the coolant duct opens into a coolant inlet at a first end face of the energy storage unit and into a coolant outlet at a second end face of the energy storage unit. All the hollow spaces associated with the energy storage unit can thus be connected in a simple manner to a common coolant supply.
  • the coolant inlet/outlet can be configured for connection to a coolant outlet/inlet of another energy storage unit.
  • a plurality of energy storage unit can thus be combined to form an overall energy storage unit (for example, vehicle battery) and be connected to a common coolant supply, wherein in each case the coolant outlet of one energy storage unit is connected to the coolant inlet of the subsequent energy storage unit such that eventually the supplied coolant flows through all the hollow spaces.
  • the invention is not only suitable for application in lithium-ion accumulators/cells, but can also be used for/in other energy storages, such as NiMH (nickel metal hydride) energy storages/cells and/or capacitor storage cells, in particular double-layer capacitor cells (supercaps).
  • NiMH nickel metal hydride
  • capacitor storage cells in particular double-layer capacitor cells (supercaps).
  • FIG. 1 shows a perspective view of two energy storage units according to the invention
  • FIG. 2 shows a cross-sectional view of a portion of one of the energy storage units according to FIG. 1 .
  • FIG. 1 shows a perspective view of two energy storage units 10 , 10 ′.
  • the two energy storage units 10 , 10 ′ are joined together in order to form a superordinate unit.
  • any number of energy storage units can be joined together in a line or be combined to form a two- or three-dimensional matrix in order to eventually constitute a vehicle battery, for example.
  • Each of the energy storage units 10 , 10 ′ comprises a plurality of prismatic cells/flat cells 12 arranged in parallel to one another in a stack.
  • the cells 12 can, for example, be lithium ion accumulator cells or double-layer capacitor cells (“supercaps”).
  • Each of the individual cells 12 has two electrode tabs 14 a , 14 b protruding from the narrow side thereof.
  • a plate-shaped interconnection board 18 serves for an electrical through-connection of the cells 12 .
  • the cells 12 are serially interconnected. Depending on the requirement profile, any other interconnection of the cells 12 can be chosen, for example, a parallel interconnection or a mixed form of serial and parallel interconnection.
  • the cells 12 of the respective stack are tensioned against one another by means of two pressure plates 15 as well as tension springs 16 . Due to this, the cells 12 are held tight, but are simultaneously enabled to “breathe”, for example, due to thermal expansion.
  • the electrical energy stored in the cells 12 can be tapped via plugs 19 arranged on opposing sides of the interconnection board 18 .
  • the interconnection board 18 is aligned at right angles to the cells 12 and completely covers one end face of the cell stack.
  • a plate-shaped cooling body 20 made of a plastic material is arranged between the interconnection board 18 and the flat cells 12 , wherein the plate-shaped cooling body 20 essentially has the same surface extension as the interconnection board 18 .
  • the interconnection board 18 has slots 22 for leading the electrode tabs 14 a , 14 b through.
  • the cooling body 20 has slots 24 , which are in registry with the slots 22 of the interconnection board 18 and are in alignment therewith.
  • the electrode tabs 14 a , 14 b are led through the slots 24 of the cooling body 20 and through the slots 22 of the interconnection board 18 and bent around at their upper ends. Further, the electrode tabs 14 a , 14 b are connected to the contact elements 40 in an electrically conducting manner, preferably by welding.
  • the contact elements 40 have bimetallic structures in order to guarantee a reduction of corrosion.
  • the cooling body 20 is formed as one piece and forms a carrier for the interconnection board 18 , which is mounted by means of fixing elements not shown, such as pressure domes and spring rings, to the top side 26 of the cooling body 20 in such a way that the interconnection board 18 contacts the cooling body 20 permanently and over its entire surface.
  • the cooling body 20 is heat-conductively connected to the interconnection board 18 , which means that heat developing in the area of the contact elements 40 can be efficiently transferred to the cooling body 20 .
  • the cooling body 20 forms a barrier between the cells 12 , which generate heat losses, and the contact elements 40 , which also give off heat losses due to the current flow. This structure enables particularly efficient heat dissipation.
  • plate-shaped cooling elements 46 are provided between adjacent cells 12 , which serve to cool the cells 12 and additionally can act as distance pieces. They are preferably formed in such a way that they are able to take up/compensate “breathing” of the cells 12 during charging and discharging operations, respectively, and dimensional changes during the service life of the cells 12 . In order to stabilize the overall structure and to improve heat conduction, the cooling elements 46 can essentially be glued over their entire surface to the respective adjacent cells 12 .
  • the cooling body 20 has, at its bottom side 28 facing towards the cells 12 , recesses 32 in which the cooling elements 46 are inserted and glued.
  • hollow spaces 34 are formed in the cooling body 20 , through which a coolant can flow in order to increase the cooling capacity in this manner.
  • Each of the cooling elements 46 has a hollow space 34 of its own assigned thereto, extending in parallel to the cells 12 and thus also in parallel to the associated cooling element 46 .
  • the hollow spaces 34 have a U-shaped cross section comprising two leg portions 36 a , 36 b directed towards the respective cooling element 46 and are arranged such that they encompass the upper end of the corresponding cooling element 46 .
  • the hollow spaces 34 are connected to one another in such a way that as a result coolant serially flows through all the hollow spaces 34 .
  • the coolant is supplied and discharged again via tubular coolant ducts 37 ( FIG. 1 ).
  • Two coolant ducts 37 are provided for each energy storage unit 10 , 10 ′, wherein the coolant ducts 37 are arranged at the side of the interconnection board 18 facing away from the cells 12 and communicate with the hollow spaces 34 from the top side 26 of the cooling body 20 .
  • the coolant ducts 37 are aligned in parallel to the cells 12 and are located each at an outer marginal area of the interconnection board 18 .
  • the coolant ducts 37 can also be aligned at right angles to the cells 12 .
  • Each coolant duct 37 has a coolant inlet 38 at one end and a coolant outlet 39 at the opposed end.
  • the configuration is such that the coolant outlet 39 of one energy storage unit 10 ′ can be inserted in the coolant inlet 38 of another energy storage unit 10 .
  • the electrode tabs 14 a , 14 b have depressions 48 leading in a cross-section to a C-shaped protrusion of a portion of the respective electrode tab 14 a , 14 b .
