Description

Field of the Invention

[0001] The present invention relates to a battery according to the type of independent claim. The subject matter of the present invention also lies in the application of such a battery. Background Art

[0002] It is known from the prior art that a battery module has a plurality of individual battery cells, each of which has a positive voltage tap and a negative voltage tap. For the conductive series and / or parallel connection of the plurality of battery cells to each other, the corresponding voltage taps are conductively connected to each other and can thus be wired into a battery module. The battery module itself is wired into a battery or a battery system. Based on a large number of feasible different vehicle installation spaces, variable module sizes are sought in order to be able to optimally utilize the existing installation space.

[0003] In addition, the battery cells of the battery module (such as lithium-ion battery cells or lithium polymer battery cells) heat up during operation due to their resistance during power output or power absorption due to chemical conversion processes. Especially in the case of relatively rapid energy output or energy absorption, these processes are relatively obvious. The stronger the power capacity of the battery or the battery module, the more significant the resulting heating and thus the more significant the requirements for an effective temperature control system. In order to increase the safety of the battery module and also to ensure the power capacity of the battery cells, it is necessary not only to heat but also to cool the battery cells of the battery module in order to be able to operate these battery cells as far as possible within a specific temperature range, so that, for example, an increase in the aging characteristics or decomposition of the monomer chemical composition can be prevented. However, the battery cells should mainly be cooled.

[0004] For example, the temperature control of the battery, i.e., heating or heat dissipation, can be configured by means of liquid temperature control using a water / ethylene glycol mixture. Here, the mixture is guided through a cooling plate arranged below the battery module. The cooling plate can be connected to the corresponding components of the cooling circuit here. Summary of the Invention

[0005] The advantage provided by the battery having the features of the independent claim is that the temperature control of the individual components of the battery can be coordinated with their respective requirements. In particular, by configuring two temperature control fluid receiving portions as temperature control spaces, the requirements for the temperature control of a plurality of battery cells and the components of the power electronics can be coordinated and optimized separately from each other. Thus, it is feasible to separate the optimization of the temperature control or heat dissipation of a plurality of battery cells from the optimization of the temperature control or heat dissipation of the components of the power electronics.

[0006] To this end, according to the present invention, a battery is provided. The battery includes a first housing element and a second housing element. The first housing element and the second housing element together form an internal space for accommodating a battery module. Herein, a plurality of battery cells of the battery module are arranged in the internal space. The plurality of battery cells are electrically interconnected in series and / or in parallel. In particular, the battery cells are herein configured as prismatic. Preferably, the plurality of battery cells are configured as lithium-ion battery cells.

[0007] In addition, a first element of a battery control device is arranged in the internal space.

[0008] The first housing element forms a first temperature control structure on a side facing away from the internal space. In particular, the first temperature control structure is also constructed on a side facing away from the second housing element.

[0009] The second housing element forms a second temperature control structure on a side facing away from the internal space. In particular, the second temperature control structure is additionally constructed on a side facing away from the first housing element.

[0010] The covering element is connected to the second housing element in such a way that the covering element limits a temperature control fluid receiving portion through which the temperature control fluid can flow. In addition, the second temperature control structure is configured to be flowed around by the temperature control fluid.

[0011] Herein, the covering element is planar and made of metal or has a forming portion (Umformung) for accommodating a second element of the battery control device.

[0012] By means of the measures recited in the dependent claims, advantageous improvements and refinements of the device set forth in the independent claims can be achieved.

[0013] An embodiment of the battery according to the present invention in particular offers the following advantages, namely, effective cooling of individual components, such as for example a plurality of battery cells and components of the power electronics, is feasible because a relatively short thermal path is constructed. At the same time, a compact construction of the battery can be provided.

[0014] Advantageously, the first element of the battery control device is thermally conductively arranged on a side of the second housing element facing the internal space. Thereby, the first element of the battery control device can be reliably temperature-controlled. The first element of the battery control device can in particular be temperature-controlled independently of the plurality of battery cells. The temperature control of the first element of the battery control device can herein be influenced by means of the construction of the second temperature control structure.

[0015] Furthermore, it is expedient that the second element of the battery control device is thermally conductively arranged on the side of the covering element facing away from the interior space and in particular from the second housing element. Thereby, the second element of the battery control device can also be reliably temperature-controlled. In particular, the second element of the battery control device can be temperature-controlled independently of a plurality of battery cells. The temperature control of the second element of the battery control device can hereby be influenced by the configuration of the second temperature control structure.

[0016] Advantageously, the second element of the battery control device comprises at least one electrical component of the battery module and / or at least one electronic component of the battery module.

[0017] Here, it is advantageous that the electrical component of the battery module is a wire. The wire is configured to conduct current from one component to another.

[0018] Preferably, the electronic component of the battery module is a switch, a fuse element, a battery control system and / or a resistor. By this arrangement of the electrical and / or electronic components of the battery, it is possible to conductively connect a plurality of battery cells of the battery module in series and / or in parallel with one another and to control and regulate the battery module. Furthermore, these components can be reliably temperature-controlled at the same time.

[0019] According to a preferred aspect of the invention, at least one electronic component is hereby integrated into a circuit board. In particular, the wire can also be at least partially integrated into the circuit board. This offers the advantage of a relatively compact construction, which can moreover be temperature-controlled simply.

[0020] Furthermore, it is expedient that the first element of the battery control device is a transformer, in particular a DC transformer. Furthermore, the transformer or the DC transformer can be arranged on another circuit board or integrated into another circuit board.

[0021] Here, a thermal compensation material, such as a thermally conductive adhesive, a so-called gap filler or a so-called thermal interface material (TIM), can also be arranged between the transformer or the DC transformer and the covering element. By connecting the transformer to the covering element, for example by means of bolts, reliable heat conduction can be achieved. Overall, this results in a relatively short heat path between the temperature control fluid flowing through the temperature control fluid receiving part of the second housing element and the transformer or the DC transformer, which hereby has a relatively low thermal resistance.

[0022] The covering element is planar and made of a metallic material or has a shaping for receiving the first element of the battery control device. In particular, the covering element is preferably made of a metal sheet here.

[0023] Here, the covering element can be connected to the second housing element, for example, in a material-locking manner, such as by welding in particular. For this purpose, the second housing element can have a connection area, for example, which is configured to be connected to the covering element in a material-locking manner. It should also be noted here that the covering element seals the temperature-control fluid receiving part hermetically with respect to the ambient fluid. In particular, such a seal can be formed by the material-locking connection of the covering element to the connection area of the second housing element.

[0024] In addition, it is also possible that the covering element can be connected to the second housing element, for example, in a form-locking manner, such as by screwing in particular. For a more reliable seal, an additional sealing element can also be arranged between the covering element and the second housing element here.

[0025] The planar configuration of the covering element offers the advantage that a similar and as large as possible thermal contact surface is formed for connecting the second element of the battery control device.

[0026] A covering element having a molding for receiving the second element of the battery control device offers the following advantages, for example: the height of the temperature-control fluid receiving part that can be traversed by the temperature-control fluid can be correspondingly matched, whereby a particularly space-optimized design can be provided. In addition, reliable accommodation of the first element of the battery control device can be provided by the molding. It should also be noted here that, for example, by means of a configuration with a bending angle, a height of the temperature-control fluid receiving part that is reduced in the flow direction or in the longitudinal direction of the temperature-control fluid receiving part can be formed.

[0027] In addition, it should be noted that the covering element is made of a metallic material. Here, the metallic material can be selected from aluminum, copper or nickel. This offers the advantage of relatively high thermal conductivity.

[0028] In particular, a thermal compensation element, such as a thermally conductive adhesive, can be arranged between the second element of the battery control device and the covering element here.

[0029] Suitably, a plurality of battery cells are arranged thermally conductively on the inner side of the interior space that is directly adjacent to the first temperature-control structure. Thereby, the plurality of battery cells can be very reliably temperature-controlled overall. In addition, the plurality of battery cells can thereby be temperature-controlled, for example, independently of the first element of the battery control device and also independently of the second element of the battery control device.

[0030] In particular, a thermal compensation element, such as a thermally conductive adhesive, can be arranged between the plurality of battery cells and the inner side here.

[0031] Advantageously, the first housing element and / or the second housing element are each configured as a die-cast housing. Thereby, a mechanically relatively stable construction can be provided. In addition, thereby it is possible to configure regions for guiding the temperature-regulating fluid within the die-cast component, such that additional cooling plates, heating elements or temperature-regulating systems can be dispensed with.

[0032] Advantageously, the first housing element and the second housing element are configured to be connected to each other in a fluid-tight manner. For this purpose, in particular, a sealing element is arranged between the first housing element and the second housing element. Thereby, a fluid-tight enclosed interior space of the battery can be provided. In particular, thereby the battery cells as well as the transformer or DC transformer can be protected from external influences.

[0033] According to a preferred aspect of the present invention, a plurality of battery cells are configured as prismatic battery cells. The prismatic battery cells in total have six sides here, which are pairwise opposite to each other and arranged parallel to each other. In addition, the sides arranged adjacent to each other are arranged at right angles to each other. In summary, a compact battery can be provided by using prismatic battery cells in the battery according to the present invention.

[0034] Advantageously, another covering element is arranged on the first housing element. In particular, the another covering element is arranged in connection with the first housing element. Here, the another covering element and the first temperature-regulating structure together form another temperature-regulating fluid receiving portion through which the temperature-regulating fluid can flow. Here, the another covering element fluid-tightly limits the another temperature-regulating fluid receiving portion with respect to the surroundings. In addition, the first temperature-regulating structure is configured to be flowed around by the temperature-regulating fluid. This provides the advantage that the first temperature-regulating structure can be matched to the requirements in terms of temperature regulation of the plurality of battery cells accommodated in the interior space. Here, such a match can be adjusted, for example, independently of the cooling of electrical components and / or electronic components and independently of the cooling of the transformer or DC transformer. For example, the first temperature-regulating structure can include turbulence elements or flow-guiding elements, which are arranged only at those positions where the temperature regulation can be actively influenced due to the required temperature of the plurality of battery cells. In addition, other regions of the other temperature-regulating fluid receiving portion can be optimized in terms of flow and pressure loss. In particular, the compromise between the temperature regulation of the plurality of battery cells and the electrical components and / or electronic components as well as the transformer can be dispensed with, since the independent temperature regulation of these components is possible.

[0035] Preferably, the another covering element is here connected to the first housing element in a material-locking manner. In particular, the another covering element can be connected to the first housing element by welding or soldering. In addition, a second sealing element can be arranged between the first housing element and the covering element.

[0036] It is also preferably possible that the another covering element is formed by the first housing element.

[0037] Overall, this provides the following advantage, namely that by such a configuration, it can be prevented that in the case of a malfunction or an unsealed part of the first temperature control space, the temperature control fluid can enter the interior space and reach the plurality of battery cells.

[0038] Advantageously, the battery includes a first terminal and a second terminal. Here, the first terminal is configured to convey the temperature control fluid to the battery and the second terminal is configured to discharge the temperature control fluid from the battery.

[0039] In particular, the first terminal and the second terminal form an interface to the motor vehicle.

[0040] According to a first aspect, the temperature control fluid can flow through one temperature control fluid receiving part and another temperature control fluid receiving part in series. Here, the temperature control fluid first flows through one temperature control fluid receiving part, for example, and then through the other temperature control fluid receiving part, or conversely, first through the other temperature control fluid receiving part and then through the one temperature control fluid receiving part.

[0041] According to a second aspect of the invention, the temperature control fluid can flow through the one temperature control fluid receiving part and the other temperature control fluid receiving part in parallel. Here, after flowing through the first terminal, the temperature control fluid is divided into a first sub-stream flowing through the one temperature control fluid receiving part and a second sub-stream flowing through the other temperature control fluid receiving part. The first sub-stream and the second sub-stream come together again after flowing through the respective temperature control fluid receiving part and are led out of the battery via the second terminal.

[0042] Thereby, for example, the pressure loss can be minimized overall. In addition, the heat transfer can be improved, for example, thereby.

[0043] In particular, the first housing element and / or the second housing element each have a temperature control fluid inlet and a temperature control fluid outlet. The respective temperature control fluid inlet is used to introduce the temperature control fluid into the one temperature control fluid receiving part or the other temperature control fluid receiving part, and the respective temperature control fluid outlet is used to discharge the temperature control fluid from the one temperature control fluid receiving part or the other temperature control fluid receiving part. In addition, the temperature control fluid outlet and the temperature control fluid inlet can also be fluidly connected to each other such that the temperature control fluid can flow between the one temperature control fluid receiving part and the other temperature control fluid receiving part or vice versa.

[0044] For example, the inlet of the temperature-regulating fluid of the first housing element may form the first terminal of the battery, through which the temperature-regulating fluid can flow in. In addition, for example, the outlet of the temperature-regulating fluid of the first housing element may be fluidly connected to the inlet of the temperature-regulating fluid of the second housing element, so that the temperature-regulating fluid can first flow through the other temperature-regulating fluid receiving portion and then flow through the one temperature-regulating fluid receiving portion, that is, a series flow-through is formed. In addition, for example, the outlet of the temperature-regulating fluid of the second housing element may form the second terminal of the battery, through which the temperature-regulating fluid can leave the temperature-regulating fluid receiving portion.

[0045] For example, the inlet of the temperature-regulating fluid of the second housing element may form the first terminal of the battery, through which the temperature-regulating fluid can flow into the temperature-regulating fluid receiving portion. In addition, for example, the outlet of the temperature-regulating fluid of the second housing element may be fluidly connected to the inlet of the temperature-regulating fluid of the first housing element, so that the temperature-regulating fluid can first flow through the one temperature-regulating fluid receiving portion and then flow through the other temperature-regulating fluid receiving portion, that is, a series flow-through is formed.

[0046] It should be noted here that such a connection between the inlet of the temperature-regulating fluid of one housing element and the outlet of the temperature-regulating fluid of the other housing element is preferably constructed within the first housing element and / or within the second housing element, and these housing elements are furthermore particularly preferably each constructed as a die-cast housing.

[0047] It is suitable that the first temperature-regulating structure and / or the second temperature-regulating structure are each constructed as a flow-guiding element, a flow-disturbing element or a flow restriction.

[0048] In particular, the first temperature-regulating structure and / or the second temperature-regulating structure can each be formed by the corresponding die-cast housing.

[0049] Here, a "flow-guiding element" should be understood as an element arranged inside the corresponding temperature-regulating space, which is used to redirect the flow without similarly increasing the turbulence.

[0050] Here, a "flow-disturbing element" should be understood as an element arranged in the corresponding temperature-regulating space, which is used to increase the turbulence of the flow, in particular to cause the transition from laminar flow to turbulent flow in order to cause improved heat dissipation in any case.

[0051] Here, a "flow restriction" is understood as an element that mechanically restricts the corresponding temperature-regulating space.

[0052] Also advantageously, the electrical and / or electronic components are thermally conductively connected to the side of the covering element facing away from the interior space. In particular, a thermal compensation element, such as a thermally conductive adhesive or a so-called thermal interface material (TIM), can be arranged between the electrical and / or electronic components and the covering element. For example, by connecting a circuit board including electronic components to the covering element, for example, also by means of bolts or a material-locking connection, reliable heat conduction can be achieved. In summary, a relatively short heat path is thus obtained between the temperature-regulating fluid flowing through the temperature-regulating fluid receiving part and the circuit board having a relatively low thermal resistance accordingly.

[0053] The subject matter of the invention also lies in the use of the battery according to the invention just described for temperature regulation and in particular for cooling a plurality of battery cells, electrical and / or electronic components and / or transformers, wherein a temperature-regulating fluid configured as a temperature-regulating liquid or a temperature-regulating gas flows around a first temperature-regulating structure, or wherein a temperature-regulating fluid configured as a temperature-regulating liquid flows through a temperature-regulating fluid receiving part.

[0054] In particular, the battery is operated in such a way that the temperature of the battery cells, preferably configured as lithium-ion battery cells, is below a temperature of 40 °C and preferably below a temperature of 35 °C. Thereby, sufficient thermal modulation of the battery can be achieved, whereby the battery cells can be operated in a non-thermally critical state, so that, for example, aging synchronization of the battery cells can be achieved, since in particular the temperature gradient between the battery cells is relatively small.
