Description

1 2295264 Cool ng device for a battery having a plurality of cells The
invention relates to a cooling device for a battery constructed from a plurality of cells.
A particular field of application of the invention relates to the cooling of traction batteries of any type for electrical vehicles. These highpower batteries require effective cooling, in order to make it possible to remove the heat losses which occur with heavy currents, since excessive heating would destroy the battery. This is all the more true for high-temperature batteries such as, for example, sodium (Na)/sulphur (S) batteries or sodium (Na)/nickel chloride (N'C12) batteries (ZEBRA), which preferably need to be operated at temperatures of 270C to 350C. In order to make it possible to keep the batteries in this operating temperature range, they need to have good thermal insulation in addition to a heating system. The better the insulation, the smaller the heat losses, and the better the energy ef f iciency of the energy drawn f rom the network, since the battery needs to be heated less. Good insulation should therefore be striven for as a matter of priority. However, on the other hand, it brings with it the disadvantage that heat losses occurring within the battery during operation are not dissipated and the temperature of the battery can thus rise above the permissible value. Thermally insulated batteries therefore have a particularly great requirement for an effective cooling device.
DE 26 38 862 A1 discloses a cooling device for cooling a battery constructed from a plurality of cells. Within a common housing, the cells are arranged in such a way that channels through which a coolant can be fed are produced between the walls of the housing and the cells, on the one hand, as well as between the walls of neighbouring cells, on the other hand. The coolant, for example a cooling liquid, is fed to the battery unit via a feed line and is again removed via a manifold line in order to dissipate the heat. The heated coolant is cooled in a heat exchanger, and 2 the cooled coolant is fed back on the output side of the heat exchanger via the feed line to the battery unit. A pump is fitted at a suitable point in order to drive the coolant circuit.
DE 74 39 582.7 U1 discloses a cooling device for a lead or steel accumulator constructed from a plurality of cells, in which cooling plates are arranged between the individual cells. In order to obtain better cooling power, the cooling plates between the individual cells can be designed as flat evaporators. These evaporators contain a liquid which boils at a temperature, below the highest permissible temperature, of approximately 500C. The evaporator is connected to a condenser by a hermetically sealed tube system. Because of the use of the heat of evaporation of the cooling liquid, such a system is particularly effective and reliable, since it has no moving parts. It may be considered a disadvantage that the cooling of the cells takes place non- uniformly, i.e. only on that surface which is in thermal contact with a cooling plate. It is furthermore not known how such a method can be used for cooling high-temperature batteries.
All cooling devices with air or a liquid as coolant investigated to date do not exhibit satisfactory results. The presented solutions either do not produce the required cooling power or are accompanied by a non- uniform temperature distribution within the battery or else within the individual cells along their height direction. The result of this is that some cells or cell regions are operated at the upper edge of the permissible temperature window and others are operated at the lower edge. This influences the internal resistance of the battery and reduces the life and its performance with a lasting effect. Because of the inadequate cooling power, it is furthermore necessary to start the cooling very early as a preventative measure, in order to avoid an impermissible temperature rise in the case of heavy and prolonged power demand. On the other hand, this involves unnecessary energy losses if, 3 because of only a low power demand, the critical temperature (upper temperature limit) had never been reached at all and the cooling had therefore been begun too early.
The present invention seeks to provide a cooling device for a hightemperature battery consisting of a plurality of cells, which allows effective and uniform cooling of the battery.
According to the present invention there is provided a cooling device for a high-temperature battery having a plurality of cells, in which the cells, around which a cooling liquid directly flows, are arranged within a common thermally insulating battery case, wherein - the boiling temperature of the cooling liquid lies within the permissible operating temperature range of the cells, - the battery case is f illed with the cooling liquid to a specific level and cooling-liquid vapour is able to collect above the level mark, - with means by which the cooling-liquid vapour is f ed to cooling and recondensing means and recondensed cooling liquid is fed back into the battery case.
With the selection of a cooling liquid whose boiling temperature lies within the permissible operating temperature range of the battery, for example close to the highest permissible operating temperature, cooling which is above all based on evaporation cooling and has some advantages is produced.
A first advantage is that a cooling effect which comes into action selectively at the location of the heating is achieved, in that wherever the local temperature at the cell surface reaches the boiling point of the cooling liquid, evaporation of cooling liquid occurs. The vapour phase rises as bubbles in the cooling liquid, as a result of which the heat is removed rapidly. Cooling thus takes place locally, only where there is a corresponding requirement for cooling.
Evaporation cooling has the further advantage that the change of physical state when the heat is absorbed by 4 the cooling liquid and the vapour bubbles are formed is accompanied by a comparatively high level of heat absorption. Since the quantity of heat to be removed is to a large extent absorbed as heat of evaporation, it is absorbed without an increase in the temperature of the cooling liquid. This contributes to a very uniform temperature distribution within the entire battery.
In all, the solution according to the invention achieves the result that the temperature in the interior of the battery is limited, in a very simple but effective manner, to a maximum operating temperature that is fixed by the boiling temperature.
In the case of conventional cooling devices, heat is removed only by mass transfer of the heated coolant (convection), so that the cooling power depends on the total throughput of the coolant and thereby on the power of a circulating pump that drives the coolant circuit. In comparison with this, the cooling device according to the invention affords the further advantage that with a corresponding design, a circulating pump is not required. The cooling circuit is set in motion and sustained only by the excess heat loss which would otherwise heat the battery to above the boiling point of the cooling liquid.
The invention is illustrated with the aid of a preferred exemplary embodiment in accordance with the drawing and described in more detail.
The single figure shows the cooling device according to the invention for a battery 1 which is constructed from a plurality of cells 3 arranged within a battery case 2. For the case of a high-temperature battery, the battery case 2 has thermal insulation which, just as a heating device which is then likewise required, is not represented in the drawing. The battery case 2 is hermetically sealed from the outside, the cooling liquid 4.1 filling the battery case 2 only up to a specific level mark 4. Above this level mark 4, the battery case 2 is filled with air or coolingliquid vapour 4.2. The level mark 4 is selected in such a way that the cells 3 are to a large extent immersed in the cooling liquid 4.1, in order to ensure uniform cooling of them. The cells 3 are arranged in such a way that channels 5, which allow unimpeded circulation of the cooling liquid 4.1, are produced between the walls of the battery case 2 and the cells 3, on the one hand, as well as between the walls of neighbouring cells 3, on the other hand. For the same reason, the cells 3 rest, separated from the bottom of the battery case 2, on a supporting base 6 which, in the manner of a grate, has a multiplicity of through-openings for the cooling liquid 4.1. In the figure, the cells 3 are represented as being connected in series from cell to cell by pole connectors.
The battery case 2 has an outlet opening 7 to which a manifold line 8, through which the cooling-liquid vapour 4.2 can escape from the battery case 2, is connected. The other end of the manifold line 8 is connected to a cooling and recondensing means, here a cooler 9. In this cooler, the cooling-liquid vapour 4.2 is cooled and is thereby recondensed to give cooling liquid 4.3 by giving up heat of evaporation into the liquid phase. In order to support the cooling power of the cooler 9, a fan 10 which turns itself on automatically according to requirements may be provided. The cooling liquid 4.3 recondensed in the cooler 9 is fed back via a feed line 11 and an inlet opening 12 into the battery 1. It is preferably fed back via a prechamber 13 which communicates with the part of the battery case 2 accommodating the cells 3 only in the bottom region. This ensures that the recondensed cooling liquid 4.3 is always fed in below the level mark 4 and is fed into the cooling liquid 4.1 already present, and does not interact with the vapour phase 4.2.
In the case of a high-temperature battery to be cooled, the manifold line 8 must be designed thermally insulated, so that no cooling-liquid vapour 4.2 is precipitated in it and is recondensed in an uncontrolled manner. The feed line 11 must likewise be thermally 6 insulated so that the cooling liquid 4.3 fed back does not cool too much. Such excessive cooling might possibly lead to an undesired temperature gradient in the cooling liquid 4.1 within the battery case 2.
A pressure-compensation tube 14 that branches vertically off from the manifold line 8 is furthermore provided above the cooler 9. It is open at the top and, in contrast to the manifold line 8, is not thermally insulated. By virtue of this pressure-compensation tube 14, when cooling enters into action the air displaced from the cooling liquid because of the vapour that forms can escape. Conversely, when the cooling again ceases to act and an underpressure is formed, air can flow back again into the cooling device through this tube. Escape of cooling-liquid vapour 4.2 is prevented in that it precipitates on the inner walls of the pressure-compensation tube 14, which is not thermally insulated, and is fed into the cooler 9 as recondensed liquid drops.
For replacement of the cooling liquid 4.1, a closable pressurized-air inlet 15, a non-return valve 16 and, finally, a closable liquid outlet 17 are provided one after the other in the flow direction in the feed line 11. During normal operation, as represented in the figure, the pressurized-air inlet 15 and the liquid outlet 17 are closed and the nonreturn valve 16 is open.
The mode of operation of the cooling device according to the invention is presented below: by virtue of the fact that the battery case 2 is not completely filled with cooling liquid 4.1, the cooling circuit, which indeed does not have a circulating pump, is not in operation as long as no cooling liquid 4.1 evaporates. Only when the boiling temperature of the cooling liquid 4.1 is exceeded locally at a cell 3 does natural circulation cooling enter into action. As the quantity of heat to be removed increases, the vapour pressure building up in the upper region of the battery case 2 as a result of the rising vapour bubbles increases. The cooling-liquid vapour 4.2 7 escapes from the battery case 2 through the manifold line 8 provided f or this purpose and recondenses in the cooler 9 by giving up heat of evaporation to the surroundings. The recondensed liquid 4.3 then returns under the influence of gravity into the battery case 2 via the prechamber 13.
A prerequisite f or the desired operation of the natural circulation cooling is that the cooler is located geodetically higher than the level mark 4 in the battery case 2. A pump would otherwise be required to deliver recondensed cooling liquid into the battery. In this case it would also be necessary for flow of cooling liquid out of the battery back into the cooler to be prevented by suitable measures.
When selecting a suitable cooling liquid, in addition to matching the boiling temperature to the highest permissible operating temperature of the battery, further points of consideration are also to be taken into account. For an optimum cooling effect, the cooling liquid should have the highest possible heat of evaporation and a high heat capacity. The cooling liquid must furthermore be electrically neutral and should not change chemically, even in the presence of an electric field, throughout the entire operating temperature range, this being the range of from -20C to 350C in the case of high-temperature batteries. The cooling liquid should still be in the liquid form at the lower limit of the operating temperature range. For reasons of operational safety and so as not to damage the environment, the cooling liquid should be non-corrosive, nontoxic, incombustible and insoluble in water.
The substance dibutyl orthophthalate (C16H2204) may be specified as a cooling liquid which is suitable, in particular, for the cooling of Na/N'C12 batteries and satisfies the abovementioned requirements. This orthophthalic acid dibutyl ester is free from fluorine and chlorine and is known as a transformer coolant used in large-scale industrial applications. The boiling point of this liquid is 335C.
