Description
The present invention relates to a battery module, in particular for an electric or hybrid vehicle. The invention also relates to such a battery module with a heat exchanger or/and a filter device.
The invention also relates to an arrangement having such a battery module and having a coolant circuit. Finally, the invention relates to an electric or hybrid vehicle with such an arrangement or with such a battery module.
Batteries used as electrical energy storage in battery-only electric vehicles and plug-in hybrid vehicles typically include a battery housing in which a plurality of battery cells are arranged. Waste heat generated by these battery cells must be removed from the battery housing to prevent overheating of the battery cells.
In this context, it is known to flow around battery cells arranged in a battery housing with a temperature control fluid, which is conducted through the interior of the battery housing, i.e. the housing interior, for this purpose. Furthermore, the battery housing is typically integrated into a fluid circuit in which the temperature control fluid circulates. By transferring heat from the battery cells to the temperature control fluid, the desired cooling of the battery cells is achieved. To ensure that coolant flows through the cell housing, a suitable delivery device (typically in the form of a cooling fluid pump) is used to deliver the temperature control fluid.
It has proven disadvantageous that the battery housing must be protected against excessive fluid pressure in order to prevent leakage, including bursting of the battery housing. Therefore, battery housings are often provided with reinforced housing walls. To this end, the wall thickness of the housing wall may be increased. As an alternative thereto, it is also known to provide the housing wall with additional mechanical reinforcements, such as rib structures or tension anchors. However, all these measures have a negative effect on the production costs and the installation space required for the battery housing.
It is therefore an object of the present invention to create an improved embodiment for a battery module comprising said battery and a delivery device, wherein said disadvantages are at least partially, ideally even completely eliminated.
This problem is solved by the subject matter of the independent claims. Preferred embodiments are the subject of the dependent claims.
The basic idea of the invention is therefore to arrange the battery and its battery cells, through which the temperature control fluid can flow, as close as possible to the suction side of the conveying device or the cooling fluid pump, respectively, for driving the temperature control fluid. In this way, the fluid pressure of the temperature control fluid in the battery or in the battery housing can be kept low in each case, so that the above-mentioned safety measures, and therefore in particular the mechanical reinforcement of the housing wall of the battery housing, can be dispensed with. This leads not only to a cost advantage for the production of the battery housing, and thus to a cost advantage for the entire battery module; the installation space requirement of the battery case is also reduced.
The battery module according to the present invention includes a battery having a battery case. A battery housing surrounds the housing interior, inside which at least one battery cell is arranged for storing electrical energy. Preferably, a plurality of such battery cells are arranged in the housing interior. The battery housing or the interior of the housing with the at least one battery cell is respectively designed to be able to be flowed through by a temperature control fluid. By flowing around the battery cells, waste heat generated in operation can thus be transferred to the temperature control fluid and can be discharged from the battery cells. The battery module also includes a delivery device for delivering the temperature control fluid through the interior of the housing. According to the invention, the battery housing is arranged on the suction side of the conveying device. A cooling fluid pump may be used as the delivery device.
According to a preferred embodiment, the battery housing comprises a cooling fluid outlet for discharging the temperature control fluid out of the interior of the housing. The cooling fluid outlet is in direct fluid communication with a fluid inlet provided on the suction side of the delivery device so that the temperature control fluid flowing out of the battery housing can be directly supplied to the delivery device.
According to a preferred embodiment, the battery module comprises a bypass through which the temperature control fluid can be led to bypass the battery cells without receiving waste heat. In the case of too high a fluid pressure being formed inside the housing, the too high fluid pressure can be reduced by the temperature control fluid not being guided through the interior of the housing but being guided around the interior of the housing. In this way, the operational safety of the battery module is also ensured when the fluid pressure in the battery module is so high that the fluid pressure will consequently also increase in the interior of the housing (for example due to contamination or clogging).
It is particularly convenient to arrange a bypass valve in the bypass, which bypass valve is adjustable at least between an open position and a closed position. In the closed position, the bypass valve prevents the temperature control fluid from flowing through the bypass. In the open position, the bypass valve unblocks the bypass for the flow of the temperature control fluid therethrough. In this way, the amount of temperature control fluid that is directed around the battery cells can be set and varied as needed or desired, respectively. In particular, the amount of temperature control fluid to be conducted past the battery cells can be set and varied as a function of the fluid pressure of the temperature control fluid in the interior of the housing or on the suction side of the delivery device, respectively.
According to a further advantageous development, the bypass can be integrated into the cell housing of the cell. Alternatively, the bypass can be integrated into the delivery device, preferably into the delivery device housing of the delivery device. Both variants of this embodiment require a particularly small installation space and also prove economical.
According to an advantageous further development, the battery housing is designed such that the housing interior enclosed by the battery housing can be flowed through at least partially by the temperature control fluid. In this further development, the bypass is connected in parallel fluidically to the interior of the housing of the cell housing. The temperature control fluid which is guided through the bypass is therefore not in thermal contact with the battery cells to be cooled which are arranged in the housing interior.
In order to form a bypass in the cell housing, particularly preferably, a channel structure can be integrated on or/and in the cell housing, in particular on the inside or/and outside, which channel structure is fluidically separated from the housing interior and runs parallel to the housing interior. This embodiment has proven to be particularly economical.
It is particularly preferred that no components which generate an additional pressure drop in the temperature control fluid are arranged between the battery and the suction side of the delivery device. This variant ensures that a fluid pressure which is usually very low on the suction side is also present in the interior of the housing with the battery cells. Particularly preferably, the battery module is therefore designed such that the pressure drop of the temperature control fluid between the cells and the suction side assumes substantially zero values. In other words, the cooling fluid pressure inside the housing of the battery housing and on the suction side of the delivery device is substantially the same.
For this purpose, it is particularly preferred that the flow path of the temperature control fluid between the battery housing and the suction side of the delivery device is at most 1cm.
According to a further advantageous development, the conveying device comprises a conveying device housing which has a conveying device housing flange on the suction side of the conveying device, through which flange the temperature control fluid can flow. In this further development, the battery housing has a battery housing flange through which a temperature control fluid can flow. In this further development, the delivery device housing flange and the battery housing flange are fastened to one another in such a way that the temperature control fluid flowing out of the battery housing via the battery housing flange can enter the suction side of the delivery device directly via the delivery device housing flange. Particularly preferably, it is contemplated that the two flanges are detachably fastened to one another, which may be achieved in particular by a screw connection.
According to a further advantageous further development, a filter device can be arranged upstream of the conveying device for cleaning the temperature control fluid, which filter device forms part of the battery module. In this way, contamination and clogging of the suction side of the conveying device can be counteracted. The undesired fluid pressure increase of the temperature control fluid in the region of the suction side of the conveying device and in the housing interior of the battery housing connected thereto is thus also counteracted.
According to another advantageous further development, a heat exchanger can be arranged upstream of the battery to remove heat from the temperature control fluid, which heat exchanger forms part of the battery module. In this way, heat may be removed from the temperature control fluid before it is in thermal contact with the battery cell to be cooled.
A further preferred embodiment proves to be particularly space-saving, wherein the filter device explained above or/and the heat exchanger described above are integrated into the delivery device, in particular into the delivery device housing.
It is particularly convenient for the filter device and alternatively or additionally the heat exchanger to be fastened to the battery, in particular to the battery housing, or/and to be fastened to the conveying device, in particular to the conveying device housing. Particularly preferably, the fastening is performed in a detachable manner, for example by means of a screw interface. This preferred embodiment facilitates a modular construction of the battery module, which can thus be supplemented in a simple manner by the assembly and thus the filter device and the heat exchanger. Of course, in a continuous variant, it is also conceivable to fasten further components to the component housing on the battery housing, alternatively to the delivery device housing.
The invention also relates to a fluid management module comprising a battery module as described above, also having a heat exchanger or/and a filter device as explained above. The above-mentioned advantages of the battery module are thus also transferred to the fluid management module according to the invention.
The invention further relates to a device having a fluid circuit, in which the battery module according to the invention described above is arranged such that, in operation of the conveying device, a temperature control fluid circulates in the fluid circuit and, when circulating, flows around battery cells arranged in a housing interior of a battery housing. The advantages of the battery module described above are thus also transferred to the device according to the invention.
Finally, the invention relates to an electric or hybrid vehicle having an electric drive system for driving the vehicle. The vehicle further comprises a battery module according to the invention as described above, or/and a device according to the invention as described above. Therefore, the above-described advantages of the battery module according to the present invention are also transferred to the electric or hybrid vehicle according to the present invention.
Further important features and advantages of the invention will emerge from the dependent claims, the figures and the associated description of the figures with the aid of the figures.
It is to be understood that the features mentioned above and yet to be explained further below can be used not only in the respectively indicated combination but also in other combinations or alone without leaving the scope of the present invention.
Preferred exemplary embodiments of the invention are shown in the drawings and are explained in more detail in the following description.
The single figure 1 illustrates an example of a battery module 1 according to the invention. The battery module 1 comprises a battery 3, which battery 3 comprises a battery housing 4, which battery housing 4 encloses a housing interior 5. In the housing interior 5, a plurality of battery cells 3a of the battery 3 for storing electrical energy are preferably arranged adjacent to one another.
The battery housing 4 is designed such that the temperature control fluid K can flow through the housing interior 5. For this purpose, the battery housing 4 comprises a cooling fluid inlet 15 for introducing the temperature control fluid K into the housing interior 5 and a cooling fluid outlet 16 for discharging the temperature control fluid K after it has flowed through the housing interior 5. When the temperature fluid K flows around the battery cells 3a arranged in the case interior 5, the battery cells 3a are cooled by the heat transferred from the battery cells 3a to the temperature control fluid K. The battery module 1 further comprises a conveying device 6, which may be formed by a cooling fluid pump 6 a. The delivery device 6 or the cooling fluid pump 6a respectively comprises a pressure side 8 and a suction side 7 arranged upstream of the pressure side 8. The battery housing 4 is arranged on the intake side 7 of the conveying device 6. The battery housing 4 is therefore not arranged on the pressure side 8 of the conveying device 6. The suction side 7 is thus in fluid communication with the housing interior 5 of the battery housing 4 for conveying the temperature control fluid K. The cooling fluid outlet 16 for discharging the temperature control fluid K from the housing interior 5 is here in direct fluid communication with a fluid inlet 18 located on the suction side 7 of the conveying device 6. The temperature control fluid K flowing out of the battery housing 4 can thus be introduced directly into the conveying device 6.
According to fig. 1, the battery module 1 can comprise a bypass 10, through which bypass 10 the temperature control fluid K can be led around the battery cells 3a without coming into thermal contact with these cells. The fact that the bypass 10 is led around the battery unit 3a does not exclude here that the bypass 10 can be integrated into the battery housing 4, as described above. The bypass 10 explained here is essentially characterized only in that the bypass 10 is fluidically connected in parallel to the housing interior 5 of the battery housing 4 or respectively fluidically extends parallel to the housing interior 5, so that the temperature control fluid K guided through the bypass 10 cannot receive any heat from the battery cells 3a of the battery 3 and can furthermore flow with as little pressure loss to the suction side of the pump as possible, so that the pressure build-up in the battery housing is low. The variant in which the bypass 10 is arranged on the outside or on the inside on the battery housing 4 meets this requirement, requires a particularly small installation space and can be implemented in a technically simple and therefore also economical manner. Thus, the bypass 10 can be integrated into the battery housing 4 of the battery 3, as a matter of convenience. Alternatively, the bypass 10 can be integrated into the conveyor housing 9, so that the bypass 10 can be provided with a bypass valve 12 inside the conveyor housing 9. Thus, a blockage or constriction in the device exterior or in the circuit, respectively, does not necessarily lead to damage as a result of too high a pressure in the battery housing 4.
In the example of fig. 1, in order to form the bypass 10 in the battery housing 4, a channel structure 17 is provided on the inside, which is fluidically separated from the housing interior 5 and extends fluidically parallel to the housing interior 5, if appropriate. The temperature control fluid K flowing through the channel structure 17 of the bypass 10 is therefore not in contact with the battery cell 3a to be cooled.
In a bypass line 11, which also forms a bypass 10 leading the temperature control fluid K around the battery unit 3a without being in thermal contact with the battery unit 3a, a bypass valve 12 may be arranged, which is adjustable between an open position and a closed position. The bypass line 11 with the bypass valve 12 can be integrated here into the battery housing 4, as shown in fig. 1, and can in particular be formed by the already mentioned channel structure 17.
In the closed position, the bypass valve 12 prevents the temperature control fluid K from flowing through the bypass 10 or the bypass line 11, respectively. In this case, the entire temperature control fluid K introduced into the battery housing 4 flows through the housing interior 5, flows therein around the battery cells 3a and, if necessary, receives waste heat generated by the battery cells 3a. In the open position, the bypass valve 12 opens the bypass 10 or the bypass line 12, respectively, for the temperature control fluid K to flow through.
In order to prevent the fluid pressure of the temperature control fluid K from becoming too high in the housing interior 5, the bypass valve 12 can be controlled by adjusting to an open position or by means of a suitable control/regulating device (not shown in fig. 1 for the sake of clarity) at least towards an open position, so that the temperature control fluid K does not reach or only partially reaches the housing interior 5, but is guided past the housing interior 5. When the fluid pressure in the region of the suction side 7 or in the housing interior 5 is below the same predetermined threshold value or another lower threshold value, respectively, the bypass valve 12 is set to the closed position by means of the control/regulating device, so that the temperature control fluid K is conducted completely or in each case in greater proportion through the housing interior 5. In the housing interior 5, the temperature control fluid K can flow around the battery cells 3a and can receive waste heat from these battery cells by heat transfer. The measurement of the fluid pressure of the temperature control fluid K required for controlling the bypass valve 12 can be carried out by means of a pressure sensor (not shown) which can be arranged at a suitable location, in particular in the housing interior 5 or on the suction side 7 of the conveying device 6.
When the bypass valve 12 is also adjustable in an intermediate position between its open position and its closed position, it itself helps to regulate the fluid pressure of the temperature control fluid K in the region of the suction side 7 or/and within the housing interior 5 by means of a control loop which achieves a target value by adjusting the setting of the bypass valve 12 to a suitable intermediate position between the open position and the closed position. In this way, an optimal throughflow of the temperature control fluid K to the battery unit 3a can be ensured. At the same time it is still ensured that the fluid pressure does not rise above the maximum permissible value.
As shown in the schematic illustration of fig. 1, no further components are arranged between the battery 3 and the suction side 7 of the delivery device 6, which would generate an additional pressure drop in the temperature control fluid K. For example, the flow path X of the temperature control fluid K between the battery housing 4 and the suction side 7 of the conveying device 6 is at most 1. The battery module 1 is therefore designed such that the pressure drop of the temperature control fluid between the cells 3 and the suction side 7 is as small as possible.
As shown only in the rough schematic illustration of fig. 1, the conveying device 6 of the battery module 1 has a conveying device housing 9. The delivery device housing 9 comprises a delivery device housing flange 9a, through which the temperature control fluid K on the suction side 7 can flow. In a similar manner, the battery housing 4 has a battery housing flange 4a, through which flange 4a the temperature control fluid K can likewise flow. The delivery device housing flange 9a and the battery housing flange 4a can be fastened to one another detachably or non-detachably, so that the temperature control fluid K flowing out of the battery housing 4 via the battery housing flange 4a can enter directly into the suction side 7 of the delivery device 6. In order to detachably connect the two flanges 4a, 9a to each other, it is considered to establish a threaded interface between the two flanges 4a, 9 a.
Furthermore, as shown in fig. 1, a filter device 13 may be provided upstream of the battery 3 for cleaning the temperature control fluid K of dirt particles and the like. In this way, such dirt particles are prevented from reaching the region of the suction side 7 of the conveying device 6 and there causing an undesired increase in the fluid pressure of the temperature control fluid K as a result of clogging.
As an alternative or in addition to the filter device 13, the heat exchanger 14 may be arranged upstream of the battery 3. In the example of fig. 1, this heat exchanger 14 is arranged, for example, upstream of the filter device 13. The heat exchanger 14 can be flowed through by another fluid F fluidly separate from the temperature control fluid K. By the heat transfer from the temperature control fluid K to the fluid F, the temperature of the temperature control fluid K is lowered so that it can receive heat again from the battery unit 3a when it flows through the battery 3 next time.
Both the heat exchanger 14 and the filter device 13 form part of the battery module 1. As can be seen from the rough schematic view of fig. 1, the filter device 13 can be equipped with a filter housing 13a. The heat exchanger 14 may also optionally be provided with a heat exchanger housing 14a. The filter device 13 and/or the heat exchanger 14 can also be integrated into the delivery device 6, in particular into the delivery device housing 9 of the delivery device 6.
Preferably, the filter housing 13a and, if present, alternatively or additionally, the heat exchanger housing 14a can also be fastened in a modular manner on the battery housing 4a or on the delivery device housing 9, respectively. Releasable fastening is considered to be preferred. The battery module 1 and the heat exchanger 14 or/and the filter device 13 can be embodied as a structural unit for forming a fluid management module.
According to fig. 1, a battery module 1 according to the invention is integrated into a fluid circuit 2, a temperature control fluid K being circulated in the fluid circuit 2 by an active conveying device 6. It should be understood that the filter device 13 and (alternatively or additionally) the heat exchanger 14 can also be arranged separately from the battery module 1 in the fluid circuit 2, for example also combined in a conveying module/conveying device.
