Description

Technical Field

[0001] The present disclosure relates to an electronic unit for a traction battery of a vehicle. The electronic unit comprises a housing. Furthermore, the electronic unit comprises at least one electronic control component and / or at least one power electronic component arranged inside the housing.

[0002] The present disclosure also relates to a seat assembly for a vehicle.

[0003] Furthermore, the present disclosure relates to a vehicle.

[0004] Furthermore, the present disclosure relates to a use of an electronic unit. Background Art

[0005] Vehicles that include a traction battery configured to provide electrical energy for driving the vehicle may be referred to as electric vehicles.

[0006] Such a vehicle usually comprises at least one electronic unit. For example, the electronic unit may form part of an inverter unit. Additionally or alternatively, the electronic unit may form part of a so-called Battery Disconnect Unit (BDU) configured to disconnect the traction battery from the remaining electrical components of the vehicle when required. The electronic unit may also form part of a Battery Management System (BMS) configured to control the operation of the traction battery.

[0007] Within the vehicle, such electronic units take up a certain amount of space which cannot be used for other functions of the vehicle (e.g. for the traction battery section and / or for passengers). In addition, the electronic units have a certain weight which is added to the gross weight of the vehicle, wherein the gross weight of the vehicle is one of the main influencing factors for the driving range of an electric vehicle. In this case, a relatively high gross weight is associated with a relatively low driving range. Summary of the invention

[0008] Therefore, an object of the present disclosure is to help reduce the overall weight of an electric vehicle. In doing so, the driving range should be improved.

[0009] This problem is at least partly solved or alleviated by the subject matter of the independent claims of the present disclosure, wherein further examples are incorporated in the dependent claims.

[0010] According to a first aspect, an electronic unit for a traction battery of a vehicle is provided. The electronic unit comprises a housing. In addition, the electronic unit comprises at least one electronic control component and / or at least one power electronic component arranged inside the housing. A mechanical connection interface for mechanically attaching a seat element is provided on the housing. In this case, the housing should be understood as a structural member that encloses and / or supports at least one electronic control component and / or at least one power electronic component. The structural member is configured to support a mechanical load. The mechanical connection interface should be understood as a device for mechanically connecting the housing to another element of the seat element (such as a seat element). The mechanical connection interface is configured to transfer a mechanical load from the housing to another element, and / or vice versa. The mechanical connection interface may be detachable or non-detachable (i.e., permanent). In the case where the mechanical connection interface is detachable, it may be manually detachable or detachable using an appropriate tool. In the case where the mechanical connection interface is non-detachable, it cannot be detached without damaging the housing, an element of the mechanical connection interface, or another element connected to the mechanical connection interface. According to an example, the mechanical connection interface is configured to transmit tension and / or compressive stress. According to another example, the mechanical connection interface can be configured to transmit shear forces. According to yet another example, the mechanical connection interface is configured to transmit torque. In other words, the mechanical connection interface is configured to block one or more mechanical degrees of freedom associated with the relative movement of the housing and another element (e.g., a seat element). Due to these characteristics of the mechanical connection interface, the housing can be used as a structural component of a vehicle in which the electronic unit is used (e.g., for mechanically supporting a seat element). Therefore, the housing is not only used to protect and / or support at least one electronic control component and / or at least one power electronic component. In addition, the mechanical stability of the housing is used to support other elements (e.g., a seat element). This has the effect of reducing the size and weight of other structural components of the vehicle or even completely eliminating other structural components of the vehicle. In short, the electronic unit enables the total weight of the vehicle to be reduced.

[0011] According to an example, the seat element may be a cushion element. The cushion element may be a rear seat cushion element. Thus, using the electronic unit of the present disclosure, the cushion element (eg, rear seat cushion element) may be installed in a vehicle interior.

[0012] In an example, the mechanical connection interface comprises at least one hole, which is configured to accommodate a bolt. Additionally or alternatively, the mechanical connection interface comprises at least one bolt, which is configured to be accommodated in a hole provided on the seat element. The mechanical connection interface comprising at least one hole and / or at least one bolt is structurally simple. In addition, such a connection interface is stable and reliable. In addition, establishing a mechanical connection using such a mechanical connection interface is relatively simple and can be automated. In summary, a mechanical connection interface comprising at least one hole and / or at least one bolt is a highly reliable and effective way of connecting an element (e.g., a seat element) to a housing of an electronic unit.

[0013] According to another example, the mechanical connection interface comprises two or more holes, wherein each hole is configured to accommodate a bolt. Additionally or alternatively, the mechanical connection interface comprises two or more bolts, wherein each bolt is configured to be accommodated in a hole provided on the seat element. The use of at least two holes and / or at least two bolts improves the ability of the mechanical connection interface to transmit torque. This is due to the fact that one of the at least two holes and / or bolts blocks relative rotation around the respective other of the at least two holes and / or bolts. Furthermore, the provision of at least two holes and / or at least two bolts improves the stability of the mechanical connection interface, in particular compared to a connection interface comprising only one hole and / or only one bolt.

[0014] In the case where the mechanical connection interface comprises one or more bolts, the bolts may be provided with threads. In this case, the mechanical connection interface may also comprise one or more nuts, wherein one nut is associated with each bolt.

[0015] According to an example, the housing comprises an upper housing part and a lower housing part. The mechanical connection interface is arranged on the lower housing part and / or on the upper housing part. In this case, the designation of the housing parts as upper housing part and lower housing part refers to the orientation of the housing during use of the electronic unit. The provision of the mechanical connection interface on the upper housing part and / or on the lower housing part allows a stable mechanical connection between the housing and the seat element.

[0016] In an example, at least one of the upper shell part and the lower shell part is cup-shaped. In this case, the corresponding other shell part can also be cup-shaped or plate-shaped. In the case where both the upper shell part and the lower shell part are cup-shaped, the shell part can also be designated as a half-shell.

[0017] In an example, the power electronic component comprises an electrical converter unit and / or a switching unit. For example, the electrical converter unit is an AC / DC converter or a DC / AC converter or a DC / DC converter. The electrical converter unit may form part of a so-called on-board charger. The electrical converter unit may also be a combination of these types of converters. The switching unit may be a safety pack disconnector, which is configured to selectively disconnect the traction battery from the remaining electrical components. The switching unit may include a fuse.

[0018] In an example, the electronic unit of the present disclosure is formed as a component of a battery pack. In this case, at least one electronic control component and / or at least one power electronic component arranged in the housing can be configured to transfer current, measurement signals and / or communication signals originating from or associated with the battery cells.

[0019] According to an example, the electronic unit of the present disclosure may form part of an inverter unit. Additionally or alternatively, the electronic unit may form part of a so-called battery disconnect unit (BDU) configured to disconnect the traction battery from the remaining electrical components of the vehicle when required. The electronic unit may also form part of a battery management system (BMS) configured to control the operation of the traction battery.

[0020] In the example, the electronic unit further comprises a mechanical support structure, which is configured to support a load originating from a seat element. The mechanical support structure is arranged inside the housing. Thus, in this example, the mechanical load is supported not only by the housing itself, but also by the mechanical support structure arranged inside the housing. This improves the load-bearing capacity of the electronic unit. Furthermore, the distribution of the load-bearing capacity between the mechanical support structure arranged inside the housing and the housing can result in a reduced weight of the electronic unit. This results in a relatively low weight of a vehicle in which the electronic unit is used.

[0021] In the example, the mechanical support structure comprises at least one electronic control component and / or at least one power electronic component. This means that the at least one electronic control component and / or at least one power electronic component is used to withstand mechanical loads originating from elements (e.g. seat elements) connected to the electronic unit via a mechanical connection interface. In other words, the at least one electronic control component and / or at least one power electronic component has not only an electrical function but also a mechanical function. This allows to further reduce the weight of the electronic unit and / or to enhance the load-bearing capacity of the electronic unit. This also makes the weight of the vehicle using the electronic unit relatively low.

[0022] According to an example, the electronic unit further comprises an electrical connection interface configured to connect at least one electronic control component and / or at least one power electronic component to a battery cell of the traction battery. Thus, the electronic unit can be electrically connected to the traction battery in a reliable manner.

[0023] According to an example, the battery cell may be located in a battery cell housing that is separate from the housing of the electronic component. However, the battery cell housing and the housing of the electronic unit may be mechanically connected. In this case, the battery cell housing may be configured to accommodate a plurality of battery cells. The battery cell housing may include a chassis on which a plurality of battery cells may be supported. Additionally or alternatively, the battery cell housing may include a support frame that holds a plurality of battery cells.

[0024] In an example, at least one battery cell of the traction battery is located in the housing. Thus, in this example, the housing of the electronics unit is a common housing for the battery cells and at least one electronic control component and / or at least one power electronic component. In this case, a plurality of battery cells of the traction battery may be located in the housing. Thus, the common housing for the battery cells and at least one electronic control component and / or at least one power electronic component may house the traction battery or may form the traction battery. The common housing may comprise a chassis on which the plurality of battery cells may be supported. Additionally or alternatively, the common housing may comprise a support frame to which the plurality of battery cells are fixed.

[0025] According to an example, the housing in which the plurality of battery cells and at least one electronic control component and / or at least one power electronic component are located is produced by casting. In an example, the common housing is cast as one component. This can make the common housing compact and cost-effective.

[0026] Note that the above examples can be combined. Then, part of the battery cells are located in separate battery cell housings and part of the battery cells are located in a common housing. In this case, at least one electronic control component and / or at least one power electronic component can be arranged on top of the battery cell.

[0027] According to a second aspect, a seat assembly for a vehicle is provided. The seat assembly comprises a seat element and an electronic unit according to the present disclosure. The seat element is attached to the electronic unit via a mechanical connection interface of the electronic unit. Thus, the housing is used as a structural component for mechanically supporting the seat element. This has the effect that other structural components of the vehicle can be reduced in size and weight or even completely eliminated. In summary, the electronic unit enables the overall weight of the vehicle to be reduced.

[0028] In the example, the seat element is attached to the electronic unit using at least one bolt. Thus, the seat element is attached to the electronic unit in a structurally simple and reliable manner. Furthermore, the use of bolts to establish a mechanical connection can be easily automated.

[0029] In an example, the seat assembly further comprises a spacer portion, wherein the spacer portion is inserted between the electronic unit and the seat element. The spacer portion can be used to bridge the geometric distance between the electronic unit and the seat element. To this end, it is necessary to adjust at least one dimension of the spacer portion (e.g., the height of the spacer portion) to the desired geometric distance. In addition, using the spacer portion, different seat assemblies can be provided in a modular manner. This means that the same electronic unit and the same seat element can be used in combination with different spacer portions, thereby adjusting the geometric distance between the electronic unit and the seat element.

[0030] According to one example, the spacer part is made of plastic, such as expanded polypropylene (EPP).Thereby, the spacer part can be produced in an efficient manner and has a relatively low weight.

[0031] According to a third aspect, a vehicle is provided. The vehicle comprises a traction battery. Furthermore, the vehicle comprises an electronic unit according to the present disclosure and / or a seat assembly according to the present disclosure. The electronic unit and / or the seat assembly are electrically and / or communicatively coupled to the traction battery. Due to the fact that the housing is used as a structural component for mechanically supporting the seat element, the size and weight of other structural components of the vehicle can be reduced or even completely eliminated. As a result, such a vehicle has a relatively low weight without compromising mechanical stability.

[0032] In an example, the traction battery comprises a plurality of battery cells arranged in a battery cell housing. The battery cell housing forms at least a part of the vehicle floor. In this case, the battery cell housing can be formed integrally with the housing of the electronic unit. Alternatively, the battery cell housing and the housing of the electronic unit can be formed separately. In the latter case, the battery cell housing and the housing of the electronic unit can be mechanically connected. In all these alternatives, forming at least a part of the vehicle floor by the battery cell housing allows the battery cell housing to be arranged in the vehicle in a space-saving manner. In other words, the electronic unit and the plurality of battery cells can be arranged close to each other, so that the conductor length can be small. At the same time, this position of the battery cell housing allows the housing of the electronic unit to be used as a mechanical support for the seat element. This can be achieved in a compact manner.

[0033] In an example, the traction battery is a structural battery. This means that the traction battery is configured to transfer and carry loads generated during use of the vehicle. Because the traction battery is a structural battery, the size and / or weight of other structural components of the vehicle can be reduced, or other structural components of the vehicle can be eliminated entirely. This allows a relatively large battery to be provided in an electric vehicle while keeping the overall weight of the electric vehicle relatively low.

[0034] According to a fourth aspect, a use of an electronic unit for a traction battery of a vehicle is provided. The electronic unit is used to attach a seat element in the interior of the vehicle. In other words, the electronic unit is used as a mechanical support for the seat element. This has the effect that other structural components of the vehicle can be reduced in size and weight or even completely eliminated. Overall, the electronic unit enables the overall weight of the vehicle to be reduced.

[0035] It should be noted that the above-mentioned examples can be combined with each other regardless of the aspects involved.

[0036] These and other aspects of the disclosure will be apparent from and elucidated with reference to the examples described hereinafter. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The drawings are merely schematic representations and serve only to illustrate examples of the present disclosure. Identical or equivalent elements are in principle provided with the same reference numerals.

[0046] Figure 1 An electric vehicle 10 is shown, which will be referred to hereinafter simply as vehicle 10 .

[0047] The vehicle 10 comprises a traction battery 12 which comprises a plurality of battery cells 14 which are arranged in a battery cell housing 16. For better visibility, only some of the battery cells 14 are provided with reference numerals.

[0048] In the present example, the traction battery 12 is a structural battery that forms part of an underfloor unit 18 of the vehicle 10. This means that the traction battery 12 is configured to withstand loads that occur during use of the vehicle 10 (e.g., in the event of a crash). At the same time, the top side of the traction battery 12 (more precisely, the top side of the battery cell housing 16) forms the interior floor of the vehicle 10.

[0049] Within the interior of the vehicle 10 , a front seat assembly 20 and a rear seat assembly 22 are provided.

[0050] Since the focus will be placed on the rear seat assembly 22 hereinafter, for ease of description, the rear seat assembly 22 will be simply referred to as the seat assembly 22 .

[0051] The seat assembly 22 includes a seat element 24 , which in this example is a lower cushion element configured to support a portion of the legs and buttocks of an occupant.

[0052] Furthermore, the seat assembly 22 includes an electronics unit 26 and a spacer element 28 .

[0053] A spacer element 28 is interposed between the electronics unit 26 and the seat element 24 .

[0054] The electronics unit 26 includes a housing 30 .

[0055] In the present example, the housing 30 comprises two housing parts, wherein the lower housing part 32 is substantially cup-shaped and the upper housing part 34 is substantially cup-shaped. In other words, the lower housing part 32 and the upper housing part 34 form half shells of the housing 30. In the present example, the lower housing part 32 is formed by casting and the upper housing part 34 is formed by sheet metal forming.

[0056] The lower housing part 32 and the upper housing part 34 are attached to each other using a plurality of screws 36. For reasons of better visibility, only some of the screws 36 have reference numbers.

[0057] Furthermore, the lower housing part 32 is mechanically connected to the battery cell housing 16. Screws are also used for this purpose.

[0058] Inside the housing 30, a plurality of electronic control components are arranged. Figure 6 and Figure 7 In FIG. 3 , an exemplary electronic control component 35 is represented in a schematic manner. In addition, a plurality of power electronic components are arranged in the housing 30 . Figure 6 and Figure 7 In FIG. 1 , an example power electronic component 37 is represented in a schematic manner. The power electronic component 37 comprises an electrical converter unit 38 (see Figure 6 and Figure 7 ).

[0059] Furthermore, the power electronics 37 include a switching unit 40 which is configured to electrically isolate the battery cells 14 from the remaining electrical components of the vehicle 10 when necessary.

[0060] It will be appreciated that the electrical converter unit 38 and the switch unit 40 need to be electrically and / or communicatively connected to the battery cells 14. A corresponding electrical connection interface is denoted by reference numeral 42.

[0061] More generally, the electronic unit 26 is a so-called battery disconnect unit (BDU) which is configured to disconnect the traction battery 12 if necessary from the remaining electrical components of the vehicle 10. Such BDUs are generally known and therefore a more detailed explanation will be omitted.

[0062] Additionally, the housing 30 of the electronics unit 26 comprises a mechanical connection interface 44 for mechanically attaching the seat element 24 .

[0063] In this example, the mechanical connection interface 44 includes two holes 46 disposed on opposing sides of the lower housing portion 32 .

[0064] Furthermore, the mechanical connection interface 44 includes two bolts 48, which are configured to extend through corresponding holes in the seat element 24. Furthermore, each of the bolts 48 is configured to extend through an associated hole 46 in the holes 46. To this end, the bolts 48 and the holes 46 may be threaded. However, it is also possible to provide the holes 46 without threads and to use nuts to secure the bolts 48 in the holes 46.

[0065] Since the spacer element 28 is interposed between the seat element 24 and the electronic unit 26, the spacer element 28 also includes an opening 50 which is configured to receive the bolt 48 (see Figures 2 to 4 ).

[0066] Thus, in the present example, the seat element 24 is mounted to the electronics unit 26 using a mechanical connection interface 44 having bolts 48 and holes 46 .

[0067] This has the effect of mechanically supporting the seat element 24 on the electronic unit 26 in the negative Z-direction. In this direction, mechanical support is provided via the spacer element 28 located on top of the electronic unit 26.

[0068] Furthermore, the seat element 24 is mechanically supported on the electronics unit 26 in the positive z-direction, since the seat element 24 is held on the electronics unit 26 by means of the screws 48 .

[0069] Furthermore, the seat element is mechanically supported in the positive and negative x-direction as well as in the positive and negative y-direction on the electronics unit 26. This is due to the fact that the mechanical connection interface 44, more precisely the bolts 48 extending through the holes in the seat element 24 and the holes 46 on the housing 30, do not allow a relative movement of the seat element 24 in or against the x-direction as well as in or against the y-direction.

[0070] Furthermore, since the bolts 48 are arranged in a separate position, the seat element 24 is supported on the electronic unit 26 such that a relative rotation between these two elements is not possible.

[0071] Consequently, the seat element 24 cannot be moved relative to the electronics unit 26 due to the connection via the mechanical connection interface 44 .

[0072] However, in order to further increase the stability of the connection of the seat element 24 inside the vehicle 10, the seat element 24 is also connected to the rear structure 52 of the vehicle 10 using two bolts 54 (see Figure 5 ).

[0073] In addition to the mechanical support of the seat element 24 by the shell 30, the seat element 24 can also be mechanically supported by a mechanical support structure 56 arranged inside the shell 30 (see Figure 6 and Figure 7 , the upper shell part 34 is shown in a transparent manner).

[0074] In the present example, the mechanical support structure 56 is formed by the electric converter unit 38. This means that the inherent mechanical stability of the electric converter unit 38 is used to mechanically support the seat element 24. This is the case in the event of a crash, as will be explained below.

[0075] A frontal collision of the vehicle 10 may have the effect of pushing a passenger seated on the seat assembly 22 (ie, seated on the seat element 24) downward and rearward (ie, in the negative z-direction). Figure 6 and Figure 7 58 in the figure. Pushing the passenger downwards causes a load to be applied to the seat element 24. This load is also directed downwards. As previously described, a portion of the load will be supported by the housing 30. In addition, another portion of the load is supported by a mechanical support structure 56 arranged inside the housing 30. In this example, the mechanical support structure 56 arranged inside the housing will only take effect when the upper housing part 34 is deformed due to this load. In the deformed state of the upper housing part 34, the upper housing part 34 and the mechanical support structure 56 formed by the electric converter unit 38 are arranged at a certain distance.

[0076] In summary, the electronic unit 26 is used to mechanically attach the seat element 24 within the vehicle 10 and to support the loads generated by the seat element 24 .

[0077] It should be noted that although this example has been explained in conjunction with a rear seat assembly 22, the teachings of the present disclosure can of course be used in conjunction with any kind of seat assembly. This means that a seat element 24 belonging to a front seat assembly or any other seat assembly can also be mechanically supported on the electronic unit.

[0078] Due to the fact that the seat element 24 is mechanically supported on the electronic unit 26, additional structures for supporting the seat element 24 in the vehicle interior can be reduced in number or in aspect or can be completely eliminated. Since such additional structures take up space in the vehicle and have a certain weight, the use of the electronic unit 26 to mechanically support the seat element 24 frees up space in the vehicle and can reduce the weight of the vehicle.

[0079] As used herein, the phrase "at least one" with respect to a list of one or more entities should be understood to mean at least one entity selected from any one or more entities in the list of entities, but does not necessarily include at least one of each entity specifically listed within the list of entities, and does not exclude any combination of entities in the list of entities. This definition also allows that entities other than the entities specifically identified within the list of entities referred to by the phrase "at least one" may optionally be present, whether related or unrelated to those entities specifically identified. Thus, as a non-limiting example, "at least one of A and B" (or equivalently, "at least one of A or B", or equivalently, "at least one of A and / or B") may refer to at least one A, optionally including more than one A, without B (and optionally including entities other than B) in one example; to at least one B, optionally including more than one B, without A (and optionally including entities other than A) in another example; and to at least one (optionally including more than one) A and at least one (optionally including more than one) B (and optionally including other entities) in yet another example. In other words, the phrases "at least one," "one or more," and "and / or" are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions "at least one of A, B, and C," "at least one of A, B, or C," "one or more of A, B, and C," "one or more of A, B, or C," and "A, B, and / or C" may represent A alone, B alone, C alone, A and B together, A and C together, B and C together, A, B, and C together, and optionally any of the foregoing in combination with at least one other entity.

[0080] By studying the drawings, the disclosure and the appended claims, those skilled in the art can understand and implement other variations of the disclosed examples when practicing the disclosure claimed for protection. In the claims, the word "comprising" does not exclude other elements or steps, and the indefinite article "a" or "an" does not exclude a plurality. A single processor or other unit can implement the functions of several items or steps recorded in the claims. The mere fact that certain measures are recorded in mutually different dependent claims does not mean that a combination of these measures cannot be used to advantage. The computer program may be stored / distributed on a suitable medium (e.g., an optical storage medium or solid-state medium provided with or as part of other hardware), but may also be distributed in other forms, such as via the Internet or other wired or wireless telecommunications systems. Any figure mark in the claims should not be interpreted as limiting the scope of the claims.
