Definitions
- the invention relates to an energy storage cell according to the preamble of claim 1, which is used in energy storage, in particular in hybrid or electric vehicles.
- hybrid or electric vehicle refers to vehicles that are inherently partially or completely driven by electrical energy.
- Hybrid-powered vehicles also called hybrid vehicles, have, for example, an internal combustion engine, an electric machine and one or more electrochemical energy stores.
- Electric vehicles with fuel cells generally consist of a fuel cell for energy conversion, a tank for liquid or gaseous energy carriers, an electrochemical energy storage and an electric machine for the drive.
- the electric machine of the hybrid vehicle is usually designed as a starter / generator and / or electric drive.
- a starter / generator it replaces the normally existing starter and alternator.
- an additional torque ie an acceleration torque
- the drive power is provided solely by an electric machine.
- Both vehicle types, hybrid and electric vehicles have in common that large amounts of electrical energy must be provided and transferred.
- hybrid controller The control of the energy flow takes place via an electronics commonly called hybrid controller. Among other things, it regulates whether and in what quantity the energy store should be taken or supplied with energy.
- the energy extraction from the fuel cell or the energy storage is generally used to represent drive power and to supply the vehicle electrical system.
- the energy supply serves to charge the memory or to convert braking energy into electrical energy, i. regenerative braking.
- the energy storage for hybrid applications can be recharged while driving.
- the energy required for this is provided by the internal combustion engine.
- lead-acid batteries, double-layer capacitors, nickel-metal hydride or lithium-ion cells can be used as energy suppliers and storage facilities for electric vehicle applications.
- the energy storage cell is housed in most cases in a gas-tight metal housing.
- a special possibility of execution in lithium-ion cells is in the form of a soft pack. This consists of the battery cell, which is surrounded by a flexible shell, typically an aluminum composite foil packaging. Due to the geometric similarity to a straight prism such energy storage cells are also referred to as prismatic energy storage cells.
- An important requirement of these energy stores is to find an optimum of the product of voltage and current for a required power. This optimization consideration includes material and cost aspects. It is found that for the intended field of application, a system design for either high voltages or high currents is not expedient.
- Typical voltage ranges for optimum system design are between 100 V and 450 V maximum voltage, the resulting currents can reach 400 A in pulsed mode, even up to 550 A for special extreme applications and for higher temperature ranges.
- Continuous currents are in the range of 80-100 A, but may also be higher depending on the application. A reduction of these currents in favor of higher voltages is associated with significantly more effort for constructive and cost-related reasons than a consistent system design for these high currents.
- WO2007 / 068223-A1 describes a battery holder with integrated cooling, in particular for receiving cylindrical galvanic cells, as they are in
- Hybrid vehicles are in use, in which the
- Energy storage are arranged in a honeycomb structure and are cooled by two basic heat sinks and at least one intermediate heat sink.
- Object of the present invention is to provide for a uniform temperature of an energy storage cell with a flexible shell.
- prismatic cells offer the advantage that the cell in
- Direction of the metallic Ableitelektroden has a high thermal conductivity.
- the thermal conductivity of the cell is significantly lower due to the insulating property of the separator layers.
- the poorer thermal conductivity of the cell is perpendicular to the Separatorlagen compensated.
- the energy storage cell is effectively cooled and / or heated via its surface.
- An essential advantage of this concept is to benefit from the good thermal conductivity of the energy storage cell in the direction of the electrodes and current conductors.
- the advantage of this concept is to fix a cell with its surface at the shortest possible distance potential-free to a heat conduction plate. Simulation results show that even with thicknesses of the thermal conductivity plates of 1 mm values of ⁇ T ⁇ 5K can be achieved with the appropriate cell geometry. The achieved cooling and / or heating is thus very effective, since there is direct contact of the energy storage cells with the heat conducting plate. Both indirect air and liquid cooling is possible. This allows optimal cooling of an energy storage device and thus particularly high life expectancy can be realized.
- the electrical insulation between the heat conducting plate and the interior of the energy storage cell is given in a typical soft pack cell already by the outer insulation (nylon) and the inner insulation (polypropylene) of the flexible sheath.
- Breathing means Volume changes that occur during normal operation. Since the energy storage cell is not clamped rigidly on both sides, but on the heat-conducting plate 'side facing away enough room for breathing is left. Volume changes occur during storage and retrieval of, for example, lithium ions in lithium-ion cells in the host grid. Likewise, in the event of abuse (overheating, overcharging), the cell may evolve gases before they are released from the cell due to the increased rise in temperature and pressure. This possibility is seen as an essential safety feature to avoid sudden pressure relief or unwanted side reactions.
- the heat-conducting plates in conjunction with the energy storage cells with a flexible casing, allow insertion and maintenance of fixed dimensions and fixing points (snap-fastening or securing of the heat-conducting plates on a tempering unit). In the case of stacking, the unfavorable addition of manufacturing tolerances of the energy storage cells with a flexible envelope is thus avoided.
- the use of the same energy storage cells with heat conducting plates for different cooling and / or heating concepts is possible.
- This offers a number of potential savings (in terms of quantities but also by reducing the number of different components), in particular for an offer of modular systems that can then be equipped with the same energy storage cells with heat conducting plates.
- the heat-conducting plate attached to an energy storage cell with a flexible envelope is thermally coupled to a tempering device.
- the tempering device is used for cooling and / or heating of the energy storage cell.
- the thermal coupling of the heat-conducting plate to the tempering device is preferably effected by fixing one end of the heat-conducting plate in the tempering device.
- Possible fixing methods are screws, clamps, crimping, wedging, gluing, riveting and / or pressing.
- the pressing is done for example by means of an outer frame.
- a particularly preferred fixing option is the wedging, wherein the wedges can be clamped by sleeves and screws. This fixation form allows a particularly good heat transfer with high vibration resistance.
- the tempering device advantageously comprises air or liquid cooling and / or heating.
- the tempering device may additionally or exclusively be arranged laterally. Also conceivable are several tempering devices from different sides in order to achieve a particularly low temperature gradient.
- the thermal connection of the battery to an external temperature control unit can also be used for targeted heating of the system at particularly low ambient temperatures, in order to ensure the most uniform possible cell temperature for this case.
- the advantage here is that the cells are heated, for example, before starting the engine in winter to a suitable operating temperature.
- prismatic energy storage cells with a flexible envelope are preferably glued on one side to a heat-conducting plate according to the invention.
- the adhesive may be liquid or in the form of a heat conducting foil.
- the adhesive fulfills the tasks of creating a good heat transfer, additionally electrically isolating (increasing the dielectric strength) and fixing the cell for further assembly.
- cooling by a tempering device can be further improved by making the attachment of the energy storage cell to the heat conducting plate inhomogeneous, for example by a triangular geometry of the adhesive zone, so that less heat is removed near the cooler than in the more remote region, ie the heat distribution or the heat gradient in the energy storage cell is counter-compensated.
- the attachment of the energy storage cell to the heat conducting plate is preferably carried out with an adhesive bond on the cell body.
- the attachment can also be done by mechanical pressure or a holder on the edge of the cell.
- the edge of the cell can be glued, clamped, screwed, riveted or nailed.
- the heat conducting plate can advantageously be used as a constructive element for fastening the energy storage cell in a frame construction.
- the heat conducting plate can preferably also be formed as a constructive element of the cell body itself. It will The cell is placed on the cooling plate and pressed on both sides of a lid construction, glued or welded.
- the heat conducting plates are made of metal, more preferably aluminum and additionally stiffened by alloying and / or a Mikroriffeiung the surface.

- the voltage is tapped.
- Fig. 2a shows a cross section of the interior of an energy storage cell (1).
- Cathode (5) and anode layers are separated from each other by a separator layer (4).
- the cathode layers (5) are derived on the left side via the inner current collector to the outer current collector (2).

- FIG. 2b shows the same cross section of the interior of an energy storage cell (1) as in FIG. 2a, only the arrow indicates the direction in which the thermal conductivity of the energy storage cell is severely limited.
- the separator layers (4) greatly restrict the heat flow. This is because the separator
- the heat-conducting plate (7) lies parallel to the electrode (5, 6) and separator layers
- the flexible sheath (3) of the energy storage cell (1) would preferably be arranged underneath the lowest separator layer (4) and below this the heat-conducting plate (7).
- Fig. 3 shows an energy storage cell (1) with a flexible sheath (3) which is flatly attached to a heat conducting plate (7).
- FIG. 4 two energy storage cells (1) are shown with flexible sheath (3), of which in each case an energy storage cell (1) on each side of a common heat conducting plate (7) is attached.
- This arrangement is called BiPack. Accordingly are at a MultiPack more than two energy storage cells (1) on one or both sides of a common heat conduction
- an energy storage cell (1) is shown, which is arranged in a housing (8) made of a material with respect to the shell (3) of the energy storage cell (1) of higher rigidity.
- the housing contributes to the fixation of the energy storage cell (1) to a heat-conducting plate (7), which is likewise arranged in the housing (8).
- the energy storage cell (1) is additionally glued to the heat conducting plate (7).
- the energy storage cell (1) and / or the heat-conducting plate (7) can also be fixed in the housing (8) by means of an adhesive device.
- the energy storage cell is mechanically stabilized. It can be seen in the illustrated embodiment of the housing (8) that the flexible sheath (3) on the front side of the energy storage cell (1) passes through a window opening of the housing (8).

- This is to be designed so that the thermal conductivity through the adhesive (9) is higher in those areas in which the energy storage cell (1) has a higher temperature according to the diagram in FIG.
- the geometry of the adhesive surface is triangular. In the upper part of this is cooled more than in the lower part and in the middle part stronger than left and right in the energy storage cell (D •
- Fig. 9 an alternative embodiment is shown.
- the heat-conducting plate (7) to which the energy storage cell (1) is attached recesses (10) in areas in which the energy storage cell (1) must be cooled less. These areas are again taken from the diagram in FIG. 7.
- a plurality of features are shown combined, which may advantageously have such recesses (10):
- the size of the recesses may preferably vary, but is also conceivable a variation of the number of recesses.
- the recesses (10) of the heat-conducting plate (7) can be designed as bores.
