Description

The invention relates to an energy supply module for a high-voltage supply unit arranged in a vehicle. The vehicle has drive wheels and an electric machine, wherein the electric machine is designed to convert its electrical energy supplied by the high-voltage supply unit into mechanical energy, thereby producing a torque which causes a propulsion of the vehicle at the drive wheels. The energy supply module is thus configured to provide a portion of the electric power supplied to the electric machine.

Nowadays, there are increasing numbers of vehicles on the market equipped with an electric drive system outlined above. This can be a hybrid vehicle or an electric vehicle. In a hybrid vehicle in addition to the electric machine another unit is used for the drive, usually an internal combustion engine. Whereas an electric vehicle is driven exclusively by an electric machine. The electrical machines used are usually constructed as internal rotor machines, in which a rotatably mounted rotor is enclosed by a stationary stator. As drive machines synchronous machines can be used, which are either permanently excited or energized. A high-voltage supply unit used in the automotive sector can have a voltage level of 250 to 420 volts, sometimes even up to 1000 volts. To achieve this voltage level, a high-voltage supply unit is constructed from a large number of energy supply cells. As a rule, the energy supply cells are connected in series. If necessary, a combination of parallel and serial interconnection can also be realized. In general, the energy supply cells are grouped into small groups, the so-called energy supply modules, which are connected in series to form the high-voltage supply unit.

Usually, the energy supply cells are designed as energy storage cells, wherein preferably lithium-ion storage cells are used as energy storage cells. A correspondingly constructed high-voltage supply unit is also referred to as a high-voltage storage or traction battery. However, it should be noted at the outset that even if reference is made below to energy storage cells, this should not have any restrictive effect. Of course, the inventive concept can also be used in connection with energy converter cells, for example in fuel cells.

At present, among other energy supply cells are used, which have a designed as a prismatic body cell housing. Such a cell case has three cell extension directions with a respective cell extension. Preference is given to using energy supply cells whose cell housing has a minimum cell extent in a cell extension direction which is smaller than the other two cell extensions and which has a maximum cell extent in a further cell extension direction that is greater than the other two cell extensions. These two cell extension directions define a pair of opposing boundary surfaces, one of these boundary surfaces being formed as a cell-contacting surface in which the two connection terminals of the energy-providing cell are arranged, and the other boundary surface is formed as a cell-mounting surface in which no connection terminals are arranged. Usually, the minimum cell extent corresponds to the width of the power providing cell and the maximum cell extent corresponds to the length of the power providing cell. The cell contacting surface and the cell mounting surface are spaced apart according to an average cell extent, namely, the height of the energy supply cell.

In the vehicles currently being marketed or marketed, the energy delivery modules are arranged such that the energy delivery cells are aligned with respect to a vehicle level defined by the vehicle longitudinal axis and the vehicle transverse axis, such that the cell contacting area and the Cell mounting surface are parallel to the vehicle level. Correspondingly, those boundary surfaces which belong to the lateral surface located between the cell contacting surface and the cell mounting surface and defined by the height are aligned orthogonally to the vehicle level. That the energy supply cells are arranged standing in the vehicle.

Although the standing arrangement of the energy supply cells has become established due to the associated advantages in the automotive industry, this arrangement also brings with it restrictions, which were not yet or only of minor importance. Due to the changing conditions in the future, among other things due to new legal requirements, for example, the impact on the achievable with a vehicle having an electric drive system range or on the have electrically realizable drive power, there is now a need for optimization. First and foremost there is the need for optimization in hybrid vehicles, in particular plug-in hybrid vehicles. In hybrid vehicles, due to the fact that in addition to the electric drive system, another unit, preferably an internal combustion engine is used for the drive, the testify in such Fahr available space anyway scarce and thus it much more difficult additional components, such as a Hochvoltver supply unit in the vehicle than in an electric vehicle. Nevertheless, the energy supply module according to the invention should not only be used in hybrid vehicles, but also in electric vehicles.

It is therefore an object of the present invention to provide a new or alternative concept for the construction of an energy supply module, which in turn enables the construction of an optimized high-voltage supply unit. On the one hand, the high-voltage supply unit should be optimized with regard to its storage capacity and, on the other hand, be optimized in terms of its structural design so that constructive free spaces within the vehicle result or develop. The optimization of the storage capacity should be such that this is accompanied by a significant improvement of the driving operation of a vehicle characterizing or representing driving parameters. At the same time, the new energy supply module is to be produced with little effort and thus cost-effectively, as well as offering maximum operational reliability.

This object is achieved by an energy supply module having a plurality of energy supply cells, at least one heat sink and bracing elements, as follows: the energy supply module according to the invention is composed of energy supply cells, each having a cell housing and two connection terminals, wherein the cell housing as a prismatic body with three cell extension directions is formed, which has a cell extension in each of these cell extension directions. In a cell extension direction, the cell housing has a minimum cell extension that is smaller than the other two cell extensions. By this cell extension direction at least two pairs of mutually opposite boundary surfaces are fixed, wherein in one of these two pairs one of the two boundary surfaces is designed as a cell contacting surface, in which the two connection terminals are arranged, and the other boundary surface is designed as a cell mounting surface in which no Connection terminals are arranged. The heat sink has a substantially prismatic heat sink housing, which in turn has a heat sink base area, a heat sink top surface, and a heat sink outer surface arranged between the two. The heat sink jacket surface has at least one pair of opposing boundary surfaces, which are designed as heat sink mounting surfaces. In the energy delivery module, the energy delivery cells are arranged in a number of superimposed cell planes substantially orthogonal to the two heat sink mounting surfaces, wherein the energy cell cells associated with a cell plane are arranged such that their minimum cell extension cell alignment direction is oriented substantially orthogonal to the cell plane is and rests on both heat sink mounting surfaces in each case at least one energy supply cell with their respective cell mounting surface. The bracing elements are pressure plates and tension elements, wherein the at least one energy supply cell applied to one of the two heat sink mounting surfaces is arranged between two pressure plates and braced by at least one associated tension element, at least one of these two pressure plates structurally independent of at least one of the two pressure plates is, between which the at least one voltage applied to the other heat sink mounting surface energy supply cell is clamped by means of at least one associated tension element.

The advantageous orientation of the energy supply cells with respect to the advantageous arrangement of the energy supply cells on the heat sink allows, in principle, the realization or the construction of an energy supply module with a low overall height or module height. This creates the prerequisite for optimizing the storage capacity of the high-voltage supply unit on the one hand and creating constructive freedom within the vehicle on the other hand. By arranging the energy supply cells within the cell planes such that each cell extension direction having the minimum cell extension is aligned substantially orthogonal to the cell plane and thus substantially parallel to the respective heat sink mounting surface, the energy providing module has a number corresponding to the number of cell planes of superimposed energy supply cells.

In the overall height or module height of the energy supply module thus enters the minimum cell expansion, in accordance with the number of superposed energy supply cells. Since the minimum cell extent is smaller than the other two cell extents of an energy providing cell, Thus, it is possible to vary the height or module height of an energy supply module with the smallest possible given by the energy supply cells gradation. Thus, the height or module height of an energy supply module can be much finer adapted to structural conditions of the vehicle, as is the case if the height or module height of the energy supply module would be predetermined by a maximum cell size or average cell size of the energy supply cell. This makes it possible to accommodate energy supply modules in installation spaces of a vehicle, which could not be used in a standing arrangement of energy supply cells so far. As an example, here in the vehicle underbody existing space is called. It can thus be used better available in a vehicle free space: with the same in a vehicle available space volume that could prin ciple be used for the accommodation of energy supply cells or energy supply modules, thus a larger number of energy supply cells in one Vehicle can be accommodated. As a result, the storage capacity, which can be implemented in a vehicle, of electrical energy that can be made available to an electric machine for realizing a propulsion of the vehicle can be significantly increased.

Accordingly, the arrangement of the energy supply cells on both heat sink mounting surfaces and thus on both sides of the heat sink contributes to a low overall height or module height of the energy supply module, since not only one side of the heat sink can be used to form a stack of energy supply cells, but both heat sink sides. Thus, the power supply cells within the power supply module can be arranged not only in height but also in area.

The fact that for the two heat sink mounting surfaces or for the two sides of the heat sink in each case a pressure plate relative to at least one of the other heat sink mounting surface or side of the heat sink associated pressure plate is structurally independent, allows a page-wise independent bracing the energy supply cells. This makes possible a simpler and more flexible construction of an energy supply module, since the energy supply cells assigned to one surface or side can each be arranged face-to-face or side-individually and then clamped. In addition, an individual clamping force can be set in each case page by page by the page-individual or side-by-side clamping of the energy supply cells. Thus, a better adapted to the particular circumstances of the energy supply cells clamping is possible, which leads inter alia to an increase in reliability.

 The concept of the invention allows the construction of a Energiebereit positioning module with low height or module height, which is why the available in a vehicle free space for the Unterbrin supply of energy supply cells can be better used. Much more energy-providing cells can be accommodated in a vehicle. In other words, it is now possible to integrate into an existing vehicle body, in particular in the body of a sedan, a high-voltage supply unit, which has a much larger storage capacity compared to previously installed high-voltage supply units.

By using energy supply modules or high-voltage supply units constructed in this way, the range achievable with a hybrid vehicle or electric vehicle can be significantly increased, sometimes doubled. Likewise, this can increase the purely electrically achievable drive power, sometimes doubling. In a hybrid vehicle, the assisting engagement of the internal combustion engine can be reduced due to the improved acceleration performance in a purely electric drive. This has a positive effect on the overall consumption and thus on the exhaust gas behavior, in particular the emission of CO ₂ . In an electric vehicle, a more agile driving behavior can be realized. Overall, the concept according to the invention is accompanied by a significant improvement of driving parameters characterizing or representing the driving operation of a vehicle.

The inventive concept also opens up constructive freedom. These free spaces can be used for example for the arrangement of components that are required for driving a vehicle. Thus, for example, in a hybrid vehicle, the fuel tank system required for the operation of the internal combustion engine can be arranged much more advantageously in the vehicle, for example in the area of the vehicle underbody. This allows an enlargement of the usable luggage space available for the transport of objects. Further, due to the fact that within a vehicle a larger number of installation locations are available for the accommodation of energy supply modules or energy supply modules, an optimization of the weight distribution within the vehicle can be achieved, away from a rear-weighted weight distribution a neutral axle load distribution. A further advantage is that cost-intensive development of new vehicle architectures to meet future range and / or consumption requirements can be avoided by the concept according to the invention, since this concept makes it possible to increase the storage capacity of the high-voltage supply unit and / or increase the purely electrically achievable drive power and on the other hand, the energy supply modules or the high-voltage supply unit realized according to this concept are now more compatible with the existing vehicle architectures. In addition, the energy supply module according to the invention is optimized production, it can be produced easily and thus inexpensively.

In order for a vehicle equipped with an electric drive system described above, and also having a vehicle level defined by a vehicle longitudinal axis and a transverse vehicle axis, to be able to set the advantages described above, an energy supply module designed according to the invention is to be arranged in the vehicle in that the cell planes of the energy supply module are substantially parallel to the vehicle level. Accordingly, the energy supply cells included in the energy supply module are arranged in the vehicle such that, for the energy delivery cells, the respective cell expansion direction having the minimum cell extent is oriented substantially orthogonal to the vehicle level. In other words, the energy supply cells included in the energy supply module are disposed in the vehicle.

 Overall, the above object is completely solved.

 In an advantageous embodiment of the invention, both pressure plates of a heat sink mounting surface structurally independent of the two pressure plates of the other heat sink mounting surface are executed. Thus, not only a printing plate structurally independent, but both printing plates. This measure allows a further simplification or flexibilization in the structure of the energy supply module. For example, the two heat sink mounting surfaces respectively associated energy supply cells can be braced independently each by means of their associated clamping elements and then the strained energy supply cells are attached to the respectively associated heat sink mounting surface.

In an alternative to the aforementioned measure embodiment only one of the two pressure plates of a heat sink mounting surface is structurally independent of the two pressure plates of the other heat sink mounting surface, the other of the two pressure plates is integral with the corresponding pressure plate of the other heat sink mounting surface. This measure allows a structurally simple, inexpensive and cost-effective design of the energy supply module. A corresponding pressure plate is to be understood as that pressure plate of the other heat sink mounting surface which, like the pressure plate, is assigned to a heat sink mounting surface of either the heat sink base surface or the heat sink cover surface. The fact that the two printing plates are made in one piece, is either on the heat sink base or on the heat sink top surface a single continuous or continuous pressure plate before. In the case of the arrangement on the heat sink base surface, such a pressure plate can simultaneously carry both the one heat sink mounting surface and the energy supply cells associated with the other heat sink mounting surface, it constitutes a load-bearing element. Thus, for example, it can be dispensed with to form the heat sink as the load-bearing element. That There are no constructive measures to provide by which this is designed to be particularly sustainable. It is possible to optimize it, for example, in terms of weight and thermal conductivity. Thus, for example, for the construction of the heat sink, a plastic material with a good thermal conductivity can be selected, which is per se lighter than, for example, a metal and which also can be dispensed with an insulating layer between the heat sink and energy supply cells. The same applies if the continuous pressure plate is arranged on the heat sink cover surface.

The cell housing should also have a maximum cell extent in a cell extension direction which is larger than the other two cell extensions. Advantageously, the cell contacting surface and the cell mounting surface should be those two boundary surfaces which are additionally defined by the cell expansion direction having the maximum cell extent. This measure has the advantage that in the installation position according to the invention, the energy supply cells abut with the boundary surface on the respective heat sink mounting surface and thus on the heat sink, which is the larger of the two candidate boundary surfaces and thus the larger area or maximum contact between energy supply cell and heat sink and thus allows a required good temperature of the energy supply cell.

In a preferred embodiment of the invention, at least two energy supply cells are arranged per cell level. Particularly preferably, exactly two energy supply cells are arranged per cell level. This allows a very compact structure as far as the footprint of the energy supply module is concerned.

 Advantageously, the energy supply module according to the invention has between one and four cell levels. The upper limit of four cells levels has the following reason: with the inventive concept should pri mär the storage capacity of a high-voltage supply unit to be increased. This is to be achieved by the fact that space available in a vehicle, which could not previously be used in a stationary arrangement or orientation of the energy supply cells in a vehicle for the accommodation of energy supply cells, can now be used. To accomplish this, the energy delivery cells are now placed horizontally in the vehicle to achieve a reduction in the overall height of the energy delivery module. Since the previously used, standing built-up energy supply cells have proven to be reliable in use as time, they should also be used for the realization of the energy supply module according to the invention. Due to the dimensions of these energy supply cells, a reduction of the module height can only be achieved in comparison with the previous stationary arrangement of the energy supply cells if four energy supply modules are arranged one above the other in the energy supply module according to the invention, or this has four cell levels. Thus, it is ensured that the overall height of the energy supply module is lower than in the case in which the energy supply cells are arranged with one of those boundary surfaces on the heat sink, which are determined by the height of the cell housing. In order not to exceed the module height, which has an energy supply module, the energy supply cells are arranged vertically, and thus to achieve a reduction in the height of the energy supply module and thus to create the ability to accommodate additional energy supply cells in previously unused space of the vehicle can the number of cell levels is limited to a maximum of four. If, on the other hand, the reduction of the module height is not the goal, for example if an energy supply module can be accommodated in a building space in which energy supply modules were already built, then an energy supply module may well have more than four cell levels with horizontally arranged energy supply cells For example, to make sure that all of the energy supply modules contained in a vehicle are of a consistent design.

Preferably, the energy supply module according to the invention has exactly two cell levels, wherein particularly preferably each of these two cell levels has exactly two energy supply cells. Overall, an energy supply module designed in this way thus has exactly four energy supply cells. With such a trained energy supply module energy supply cells can be accommodated in many construction spaces in addition, which could not be used for this purpose. At the same time, the ratio of recovered additional storage capacity and the associated additional financial expense is particularly good in such trained energy supply module.

Advantageously, the tension elements each have a fastening component in a first region. This measure has the advantage that the strained energy supply cells and thus also the energy supply module can be fastened to a receiving plate of the high-voltage supply unit without impairing the accessibility of the connection terminals of the energy supply cells. Preferably, the first region of the heat sink base is assigned, whereby a particularly simple and reliable installation is possible.

Advantageously, the tension elements each have a bracing component in a second area. Thus, it is possible to press the energy supply cells using these components against the heat sink or to clamp against it. For this purpose, a screw can be passed through both Verspannkomponenten and screwed into a counter thread having a counterpart. Alternatively, one of the two Verspannkomponenten may have required for screw Ge gengewinde. Preferably, the second region lies approximately at half the height of the tension element or in that half of the tension element which faces the heat sink surface. In particular, when arranged at half Zugelementhöhe a uniform clamping of the overlying energy supply cells can be achieved against the heat sink. In the event that the Verspannkomponente is in the heat sink top surface facing half, it tends to be in the range of half Zugelementhöhe arranged to achieve a uniform clamping even.

In a preferred embodiment of the invention, the energy supply module has two Terminal connection components, wherein each of the two heat sink mounting surfaces is assigned to each one terminal connection component. This measure enables a simple construction of the connection terminal connection component. Each of the two heat sink mounting surfaces and thus the power supply cells applied to this heat sink mounting surface is thus assigned a connection component. This allows a simple structural design of the connection component, since with it only the connection terminals of arranged on one side of the heat sink energy supply cells must be interconnected. This also results in a simple structural design of the energy supply module. In addition, this measure leads to an increase in the number of identical parts installed in a high-voltage supply unit and thus to an advantageous cost situation.

In an advantageous embodiment of the aforementioned measure, the connection terminal connection component has at least one connector part. This makes it possible to realize a serial connection of the individual energy supply modules arranged in a high-voltage supply unit. The connector part may be the male part or the female part of a connector. Before preferably the interconnection of the individual Energiebereitstellungsmo modules by means of cables, which have the corresponding required complementary, required to form the connector connector parts. Cables have the advantage that they can be prefitted in a simple manner adapted to the corresponding structural conditions, and allow easy installation due to their flexible design.

Preferably, the terminal connection component comprises a support frame and a number of terminal connectors attached to the support frame. The terminal connectors are arranged on the support frame such that the connection terminals of the energy supply cells are connected to one another in such a way by the terminal connectors that a series connection of the energy supply cells applied to a heat sink mounting surface results. Thus, the power supply cells arranged on one side of the heat sink are serially connected to each other through the terminal connection components. Further preferably, the connection terminal connection component has a number of detection means with which it is possible to detect at least one operating parameter for at least one of the energy supply cells arranged on the heat sink mounting surface. As a result, monitoring of the energy supply cells can be realized. The operating parameter can be, for example, the cell voltage applied to an energy supply cell, in which case the associated detection means are voltage taps which are in electrical contact, for example, either directly or indirectly, for example via a terminal connector, with a connection terminal. The operating parameter may also be a temperature prevailing at an energy supply cell. In this case, it may be provided, for example, to assign a temperature sensor to each energy supply cell or to provide a temperature sensor arranged on the connection terminal in such a way that, by virtue of its arrangement, makes it possible to detect a temperature which is representative of the energy supply cells arranged on the heat sink mounting surface.

In an advantageous embodiment of the invention, the energy supply module has a side connection component which is designed to connect at least one of the energy supply cells applied to one heat sink mounting surface to at least one energy supply cell applied to the other heat sink mounting surface. Thus, in a simple manner, the total energy supply cells belonging to the energy supply module can be interconnected. With the aid of the side connection component, a serial connection of the energy supply cells applied to one heat sink mounting surface to the energy supply cells applied to the other heat sink mounting surface can be realized. Overall, it is thus possible to realize a serial interconnection of all energy supply cells contained in the energy supply module.

In an advantageous embodiment of the aforementioned measure, the side connection component is bow-shaped, with a rectangular cross-section, the cross-sectional height is smaller than the cross-sectional width. This measure helps to realize an energy supply module with a low overall height and at the same time to provide a sufficiently large line cross section over which a correspondingly large current can flow between the energy supply cells arranged on one side of the heat sink and the energy supply cells arranged on the other side of the heat sink.

Due to the prismatic design of the heat sink, the heat sink jacket surface has two further boundary surfaces lying opposite one another, wherein two fluid connections are arranged on one of these further boundary surfaces, one of which is designed as a fluid inlet and the other as a fluid drain. By this measure, it is possible to supply the cooling body via one and the same boundary surface and thus on one and the same side of the temperature of the arranged on the heat sink energy supply cells serving fluid and dissipate again. By this measure, the leads, with which the individual heat sink and thus energy supply modules are supplied with the fluid and with which the fluid is discharged again, can be arranged to save space in the high-voltage supply unit. In this constructive embodiment of the heat sink, a fluid deflecting element is consequently arranged in its interior, so that the fluid supplied via the one further limiting surface can be discharged from the heat sink again via the same limiting surface. Although this Fluidumlenkelement and the resulting leadership of the fluid lines in its interior lead to the fact that the heat sink is more complex in its structural design, as yet to be described, realized according to an alternative embodiment heat sink, but it allows an advantageous routing of the fluid-carrying leads ,

In the case of the alternatively configured heat sink, each of the two further boundary surfaces has a fluid connection, wherein the fluid connection of the one boundary surface is the fluid inlet and the fluid connection of the other boundary surface is the fluid outlet. In this embodiment, the cooling body is realized less expensive in view of the leadership of the fluid lines in its interior.

In an advantageous embodiment of the aforementioned measure, the fluid connection is designed as a carrier element which has a pair of opposing carrier element base surfaces, wherein the Trägerele element base surfaces are aligned substantially parallel to the Kühlkörmontageflächen, and wherein in one of the two carrier element base surfaces a coupling sleeve is arranged. In view of the structural design of the heat sink, this measure allows the use of a prismatic heat sink, which has a small thickness. Thus, a correspondingly large flow through the heat sink can be achieved with a fluid over the coupling piece, which is required for a good temperature of the energy supply cells, the coupling piece has a correspondingly dimensioned cross-section. As a result of the fact that the coupling stub is virtually unscrewed from the further boundary surface, the heat sink width can be determined independently of the cross section of the coupling stub. A heat sink with a not too large width allows for a small-building energy supply module and on the other hand a particularly good temperature of the energy supply cells, since the fluid flows at a smaller distance and thus "more directly" to the energy supply cells.

1 shows a vehicle constructed as a hybrid vehicle 10 , which is designed as a parallel hybrid vehicle, preferably with the functionality of a plug-in hybrid. That the following statements are made in connexion with a hybrid vehicle should not have any restrictive effect. Of course, the inventive concept can also be used in egg nem electric vehicle.

The vehicle 10 has drive wheels 12 and non-powered wheels 14 on. The vehicle 10 has an electric machine 16 on that over a gearbox 18 and a differential 20 technically with the drive wheels 12 connected is. At the electric machine 16 it can be a permanent-magnet or current-excited synchronous machine. Preferably, it should be a permanent-magnet hybrid synchronous machine. The electric machine 16 is via one of a drive unit 22 controllable inverter 24 with a high voltage unit 26 connectable. The inverter 24 has a plurality of inverter switches arranged to a full bridge designed for three-phase operation. The inverter switches may be, for example, MOSFET transistors or IGBTs.

As the illustration in 1 it can be seen, is the high-voltage supply unit 26 constructed from a variety of energy supply modules, one of which is exemplified by the reference numeral 28 is marked. The energy supply module 28 in turn is constructed from a plurality of energy supply cells, one of which is exemplified by the reference numeral 30 is marked. With a block 32 is indicated that in the high-voltage supply unit 26 in addition to the components required for the storage of electrical energy further components required for the realization of control and / or monitoring functionalities are included. So it may be at the block 32 to act a parent monitoring and / or control unit, for example, a so-called SME unit act. Other components necessary for the operation of the high voltage power supply unit 26 Usually included in the water are in 1 not shown for reasons of clarity, but this should not have any limiting effect.

The electric machine 16 is trained to take her from the high voltage supply unit 26 to convert supplied electrical energy into mechanical energy, thereby at the drive wheels 12 a propulsion of the vehicle 10 To generate acting torque. The energy supply modules 28 are each designed to be a part of the electrical machine 16 provide supplied electrical energy.

Generalized is between the high voltage supply unit 26 and the electric machine 16 an exchange of electrical energy possible. Will the electric machine 16 operated by a motor, this is how it starts from the high-voltage supply unit 26 electrical energy supplied. Will the electric machine 16 powered by a generator, then the high-voltage supply unit 26 electrical energy with the electric machine 16 is generated, supplied for the purpose of storing.

In addition to the electric machine 16 has the vehicle 10 via an internal combustion engine 34 that has a clutch 36 and the gearbox 18 as well as the differential 20 the drive wheels 12 of the vehicle 10 can drive. The drive wheels 12 can do it alone by the electric machine 16 or by the internal combustion engine alone 34 or be driven in combination by both.

The vehicle 10 has a vehicle longitudinal axis 38 and a transverse transverse axle 40 on, as well as defined by these two axes vehicle level 42 ,

The schematic representation in 1 is reduced to the essential components of the drive train. The illustration of this removable connection of the electrical machine 16 to the gearbox 18 should have no restrictive effect on the concrete mechanical design. Like all energy supply modules, the energy supply module according to the invention also has a multiplicity of energy supply cells, at least one heat sink and bracing elements.

In 2 is schematically an energy supply cell 30 illustrated how it can be installed in the energy supply module according to the invention.

The energy supply cell 30 has a cell case 44 and two connection terminals 46a . 46b on. The trained as Pluspol cell terminal 46a is electrically conductive with the cell housing 44 connected. The trained as a negative terminal cell terminal 46b is by means of an insulating element 48 opposite the cell case 44 electrically isolated. As the illustration in 2 it can be seen, is the cell housing 44 formed as a prismatic body with three cell extension directions, namely a cell longitudinal extension direction 50 with a cell extension, referred to as cell length L _ZE , of a cell transverse extension direction 52 with a cell extent designated as cell width B _ZE and a cell extension direction 54 with a cell height designated as cell height H _ZE .

As the illustration in 2 can also be seen, the cell housing 44 in a cell extension direction, a minimum cell extent that is smaller than the other two cell extents. This is the cell transverse expansion direction 52 and the cell width B _ZE . It also has the cell case 44 in one cell extension direction, a maximum cell extent greater than the other two cell extensions. This is the cell's longitudinal extension direction 50 and the cell length L _ZE . By the cell expansion direction having the minimum cell extension, namely, the cell lateral extension direction 52 At least two pairs of mutually opposite boundary surfaces are defined, namely a first pair 56 of boundary surfaces and a second pair 58 of boundary surfaces, due to the in 2 selected representation of the two pairs only one of the two boundary surfaces is visible. At the first pair 56 of boundary surfaces is one of the two boundary surfaces as cell contacting surface 60 formed in which the two connection terminals 46a . 46b are arranged. The other boundary surface is as a cell mounting surface 62 formed in which no connection terminals are arranged. At the cell contacting surface 60 and the cell mounting surface 62 Thus, these are the two boundary surfaces defined by the cell expansion direction cell minimum expansion direction and the cell extension direction cell maximum expansion direction. In other words: the cell contacting surface 60 and the cell mounting surface 62 are determined by the cell width B _ZE and the cell length L _{ZE of} the cell housing or the energy supply cell. It is therefore the two boundary surfaces in which a first side length of the cell width BZE and a second side length of the cell length L _ZE correspond.

What the cell case 44 At this point, the following should be noted: The cell housing 44 is formed as a prismatic body having a cell base surface, namely the cell mounting surface 62 a cell face, namely the cell contacting area 60 and a cell envelope disposed between these two 64 having. The cell mounting surface 62 and the cell contacting area 60 are spaced apart according to the cell height H _ZE . In 2 the cell housing is shown as a prismatic body, the boundary surfaces, all of which correspond to rectangles, wherein the cells in the cell surface 64 disregarded contained phases are disregarded. In the 2 chosen representation should have no limiting effect. The energy supply cell can also be designed in such a way that the cell base area and the cell cover area do not correspond to a rectangle but to any desired corner, for example a hexagon, preferably a hexagon, which has two very long side lengths and four very short side lengths and thus is not all that very different from a rectangle.

For the sake of completeness, it should be mentioned that the energy distribution cell 30 a vent valve 66 having. Preferably, the energy supply cell 30 be designed as Energiespeciherzelle, in particular as a lithium-ion memory cell.

In 3 is a schematic representation of the arrangement of the energy supply cells shown in an executed according to a preferred embodiment energy supply module. In 3 only the energy supply cells are shown, the other components are omitted for reasons of clarity. The remaining components are shown successively in the following figures and then described on the basis of these. That the in 3 shown energy supply cells compared to in 2 illustrated power supply cell are slightly different, is not intended to have a limiting effect.

In the preferred embodiment, the power delivery module is to have four power supply cells 30 which are in two superimposed cell levels 68 are arranged. That means in every cell level 68 are exactly two energy supply cells 30 arranged. This is not intended to be limiting. Of course, more than two energy supply cells can be arranged within a cell level.

If it is not primarily about creating a power supply module with a reduced or particularly low module height or height, then a power supply module may well have more than four cells levels. However, when it comes to providing a power supply module having a height reduced in comparison with the height of an energy supply module in which the individual power supply cells are arranged upright, the number of cell planes is limited to four.

As the illustration in 3 it can be seen are the energy supply cells 30 within a cell level 68 arranged such that the superimposed energy supply cells 30 with a to the cell surface area 64 associated limiting surface, with the larger boundary surfaces. Preferably, in each case one in between the superposed energy supply cells 3 Not shown insulation sheet arranged. At the same time the energy supply cells 30 within a cell level 68 be arranged so that they are with their cell mounting surface 62 are opposite.

4 shows in a further schematic representation of four embedded in Verspannelemente energy supply cells.

As related to 3 executed, is designed according to a preferred embodiment, energy supply module two cell levels 68 each with two energy supply cells 30 and thus two pairs of superposed energy delivery cells 30 exhibit. As the illustration in 4 As can be seen, the two belonging to a pair, superimposed energy supply cells 30 between two printing plates 70 arranged and by means of two tension elements 72 clamped together, the tension elements 72 are preferably designed as tie rods.

As the illustration in 4 it can also be seen, have the tension elements 72 each in a first area 74 a fastening component 76 on. The fastening component 76 is each as one out of the plane of the tension element 72 protruding projection formed, the one through-bore 78 whose axis is substantially orthogonal to the cell planes 68 is aligned. In the respective through hole 78 a screw can be inserted, which engages in a thread located in a receiving plate, not shown. Thus, the strained energy supply cells can be attached to the receiving plate. As far as the installed state is concerned, the receiving plate should be designed to be load-bearing, ie the receiving plate supports the energy supply cells or energy supply modules attached to it against gravity. This means that in a vehicle standing or driving on a road, the mounting plate mounted therein has a smaller distance to the road surface than the energy supply cells or energy supply modules attached to it. The receiving plate is located between the energy supply cells and the road surface or below the energy supply cells. Based on the installation situation in a vehicle is thus the first area 74 in a lower half of the tension element or is the first area 74 a heat sink base of a heat sink to be described later.

Furthermore, the tension elements 72 each in a second area 80 a clamping component 82 on. The clamping component 82 is considered one out of the plane of the tension element 72 protruding projection formed, which has a through hole 84 which is substantially parallel to the cell planes 68 is aligned. With the help of the clamping components 82 is it possible the energy supply cells 30 to press against a heat sink to be described or to clamp against this. For this purpose, a screw through both Verspannkomponenten 82 guided and screwed into a mating threaded counterpart, such as a nut.

In the 5 . 6 and 7 is an energy supply module 86 presented in connection with the in 3 and 4 Compo components described are arranged in a corresponding manner.

As the representation in the 5 . 6 and 7 can be seen, the energy supply module 86 a heat sink 88 on. The heat sink 88 in turn, has a substantially prismatic heat sink housing 90 on, with a heat sink base 92 , a heat sink cover surface 94 and one between these two arranged heat sink surface area 96 , wherein the heat sink surface area 96 at least one pair of opposing, as heat sink mounting surfaces 98 having trained boundary surfaces. The heat sink housing 90 has a prismatic body 100 on, which has three basic body expansion directions with associated basic body expansions, namely a basic body longitudinal expansion direction 102 with a body length L _GK , a body transverse extension direction 104 with a body width B _GK and a body extension direction 106 with a body height H _GK . The main body width B _GK and thus the heat sink width is smaller than the main body height H _GK and thus the heat sink height and smaller than the main body length L _GK and thus the heat sink length. As the illustration in 6 it can be seen, is the main body 100 and thus the heat sink may be formed such that the main body length L _GK and thus the heat sink length substantially corresponds to the cell length L _ZE .

As the illustration in 6 it can be seen further, is the heat sink top surface 94 and thus also the heat sink base area 92 determined by the basic body length L _GK and the body width B _GK . Consequently, the heat sink is 88 so between the to the energy supply module 86 belonging energy supply cells 30 arranged that on both sides of the heat sink 88 lying energy supply cells 30 corresponding to the main body width B _GK and the heat sink width are spaced from each other.

The heat sink surface 96 has two more opposing boundary surfaces 108 on, wherein at one of these other boundary surfaces 108 two fluid connections 110 are arranged, one of which is designed as a fluid inlet and the other as a fluid drain. In this structural design of the heat sink 88 a non-visible fluid deflecting element is arranged in its interior, so that via the one further boundary surface 108 supplied fluid on the same other boundary surface 108 back out of the heat sink 88 can be discharged. Each of the two fluid connections 110 is as a carrier element 112 formed, which is a pair of opposing Trägerelementgrundflächen 114 wherein the carrier element base surfaces 114 substantially parallel to the heat sink mounting surfaces 98 are aligned, and wherein in one of the two carrier element base surfaces 114 a coupling socket 116 is arranged. Preferably, the coupling neck should 116 be designed as a quick coupling neck. Thus, to be described leads in a simple manner to the energy supply module 86 be connected. For this purpose, firmly connected to the supply lines coupling elements 118 on the coupling socket 116 be plugged.

As can be seen from the above, the heat sink housing is seated 90 from a prismatic body 100 and two fluid ports 110 together. In an alternative embodiment it can be provided that each of the two other boundary surfaces 108 one fluid connection each 110 having. The fluid may be gaseous or liquid or a two-phase mixture. The fluid may be, for example, a refrigerant or a coolant.

As in particular the representation in the 4 and 7 it can be seen, both are printing plates 70 the one heat sink mounting surface 98 structurally independent of the two pressure plates 70 the other Kühlkörpermon day space 98 executed. That is not just a printing plate 70 , but both printing plates are designed structurally independent. This is not intended to have any restrictive effect. In an alternative embodiment can also be seen easily that only one of the two printing plates 70 the one heat sink mounting surface 98 structurally independent of the two pressure plates 70 the other heat sink mounting surface 98 is executed, the other of the two printing plates 70 integral with the corresponding pressure plate 70 the other heat sink mounting surface 98 is executed. Advantageously, the two of the heat sink base 92 associated printing plates 70 made in one piece. Consequently, in this alternative embodiment, at least one of the two printing plates 70 a heat sink mounting surface 98 structurally independent of at least one of those two printing plates 70 the other heat sink mounting surface 98 executed.

The energy supply module 86 has two connection terminal connection components 120 on, with each of the two heatsink mounting surfaces 98 one connection terminal connection component each 120 assigned. Each connection terminal connection component 120 in turn has at least one connector part 122 on. By means of the connector parts, it is possible a serial connection of the individual in a high voltage power supply unit 26 arranged energy supply modules 28 to realize. For this purpose, the connector parts 122 different energy supply modules 28 for the realization of electrical connections cable plugged. In the connector part 122 it can be the male part or the female part of a connector. The cables have the corresponding required complementary, needed to form the connector connector parts.

Preferably, the terminal connection component 120 a support frame 124 and a number of on the support frame 124 fastened terminal connector, some of which are exemplified by the reference numeral 126 Marked are. The terminal connector 126 are doing so on the support frame 124 arranged that through the terminal connector 126 the connection terminals 46a . 46b the energy supply cells 30 are connected to each other in such a way that a series connection of the on a heat sink mounting surface 98 adjacent energy supply cells 30 results. That is, on one side of the heat sink 88 arranged energy supply cells 30 are through the connection terminal connection component 120 interconnected serially.

More preferably, the connection terminal connection component 120 a number of detection means with which it is possible for at least one of the on a heat sink mounting surface 98 arranged energy supply cells 30 to capture at least one operating parameter. By way of example, the detection means may be voltage taps, such that those on an energy supply cell 30 adjacent cell voltage can be determined. In 5 a voltage tap is exemplified by the reference numeral 128 characterized. It may also be a temperature sensor, for example, in the connector part 122 is integrated and with the at least one energy supply cell 30 which can be detected at this prevailing temperature.

The individual terminal connectors 126 are with the respectively associated connection terminals 46a . 46b connected, for example, welded, so that the connection terminal connection component 120 in total with the energy supply module 86 connected is.

The energy supply module 86 also has a side connection component 130 formed to at least one of the one heat sink mounting surface 98 adjacent energy supply cells 30 with at least one on the other heat sink mounting surface 98 adjacent energy supply cells 30 connect to. Using the page connection component 130 Can be a serial connection between the on the two heat sink mounting surfaces 98 each adjoining energy supply cells 30 will be realized. Thus, it is possible to have a serial connection of all in the power supply module 86 contained energy supply cells 30 to realize. The side connection component 130 is with the appropriate connection terminals 46a . 46b firmly connected, for example, welded. The side connection component 130 is designed bow-shaped, with a rectangular cross-section whose cross-sectional height H _{SVK is} smaller than the cross-sectional width B _SVK . By this dimensioning is a strong current capable embodiment of the side connection component 130 ensured.

In the 8th to 11 is the one in a vehicle 10 included high voltage supply unit 26 shown.

As in particular the perspective oblique view in 8th can be seen, the high-voltage supply unit 26 a flat-building section 132 and a towering section 134 on. The flat-building section 132 should be in the area of the underbody of the vehicle 10 be arranged, the building section 134 in a rear area of the vehicle 10 , For example, in the area of a arranged in the rear of the vehicle seat. The space available in the area of the subfloor has a very low overall height, so that in any case in the flat-building section 132 Inventively designed energy supply modules 28 are arranged. But it also makes sense in the high-build section 134 built according to the invention formed energy supply modules. On the one hand, this ensures that inside the vehicle 10 only energy exchange modules are built, which are constructed according to a single concept. On the other hand, it is possible to arrange or accommodate energy supply modules and thus energy supply cells in subsections in which this has hitherto not been possible due to the stationary arrangement of the energy supply cells. In the 10 and 11 a few of the energy supply modules are identified by the reference numeral 28 characterized. As the illustration in 9 it can be seen, are the energy supply modules 28 on a receiving plate 136 arranged or attached to this. The reference to the subfloor in the foregoing is not intended to be limiting. Of course, energy supply modules according to the invention can also be arranged in the vehicle at other locations with a low overall height.

As in particular the representation in the 9 to 11 it can be seen, are the energy supply modules 28 such in the vehicle 10 arranged that the cell levels 68 essentially parallel to the vehicle level 42 are. Accordingly, those are in an energy supply module 28 contained energy supply cells 30 such in the vehicle 10 arranged that for the energy delivery cells 10 the respective cell expansion direction cell extension direction substantially orthogonal to the vehicle level 42 is aligned. Or put another way: in the energy supply module 28 contained energy supply cells 30 are lying in the vehicle 10 arranged.

In the in the 12 to 15 presented energy supply modules 28 are the heatsinks 88 each formed according to a first embodiment. These heatsinks 88 pointing to one of the other two boundary surfaces 108 two fluid connections 110 on. This allows a space-saving arrangement of those supply lines within the high-voltage supply unit 26 with which the individual heatsink 88 and thus energy supply modules 28 be supplied with fluid and with which the fluid is discharged again. Like that 12 to 15 can be seen, these leads, namely a supplying supply 138 and a disposable supply line 140 on one and the same page of energy supply modules 28 to be ordered.

In the in the 16 to 18 presented energy supply modules 28 are the heatsinks 88 each forms out according to a wide embodiment. In 17 is one of the heat sink by way of example with the Bezugszei chen 88 characterized. In such an alternative designed heat sink 88 points each of the other two boundary surfaces 108 a fluid connection 110 on. As a result, the supply line running 138 and the disposable supply line 140 on different sides of the energy provisioning modules 28 ,

Regardless of the specific embodiment of the heat sink, the supplying supply line is an inlet, via which the energy supply modules and thus the cooling bodies cold fluid is supplied. Accordingly, the disposing supply line represents a return, via which hot fluid is discharged from the energy supply modules and thus the heat sinks.

The 11 to 16 and 18 Furthermore, the interconnection is in a high-voltage supply unit 26 contained energy supply modules 28 refer to. To realize the interconnection arranged on the energy supply modules connector parts 122 electrically connected by cable. In the 11 to 16 and 18 are individual connector parts with the reference numeral 122 or alternatively individual connection terminal connection components, which, as stated above, have connector parts, with the reference numeral 120 and individual cables with the reference numeral 142 characterized.

In particular, the representation in the 4 to 7 shows that the energy delivery cells 30 in a number of to the two heat sink mounting surfaces 98 substantially orthogonally aligned, superimposed cell planes 68 are arranged, wherein the one cell level 68 associated energy supply cells 30 are arranged such that their cell minimum expansion (cell width B _ZE ) having cell extension direction (cell transverse extension direction 52 ) each substantially orthogonal to the cell plane 68 is aligned and on both heatsink mounting surfaces 98 in each case at least one energy supply cell 30 with their respective cell mounting surface 62 is applied. The energy supply cells 30 are part of an energy supply module 86 arranged such that the respective cell mounting surface 62 and cell contacting area 60 essentially orthogonal to the cell plane 68 is aligned. Because of the energy delivery cells 30 with its cell mounting surface 62 on the heat sink mounting surface 98 abut, are the energy supply cells 30 with the heat sink 88 in a heat transfer enabling active compound. That is the heat sink 88 can at the energy supply cell 30 absorb heat that accumulates during their operation and remove it from it. Due to the pressure plates and the tension elements, the energy supply cells are clamped along their cell expansion direction having the minimum cell extent. The heat sink is formed substantially prismatic. It has a pair of opposed boundary surfaces formed as heat sink mounting surfaces. As a result, two sides of the heat sink, on which energy supply cells are arranged, are defined by these two surfaces.

The structurally independent design of the printing plates results in the at least one energy supply cell applied to the one heat sink mounting surface being clamped independently of the at least one energy supply cell applied to the other heat sink mounting surface. That it is possible a mutually interaction-free clamping.

Especially in the 12 to 18 For reasons of clarity, not all identical components are identified by reference symbols.

 The inventive concept for the construction of energy supply modules is characterized in that in a power supply module, a centrally arranged heat sink is included and the modules belonging to the Mo energy supply cells according to a tandem arrangement on both sides of the heat sink to the heat sink mounting surfaces.
