[0002] DESCRIPTION

[0003] The present invention relates to a housing, in particular for an energy storage device.

[0004] Energy storage enclosures are designed to house the energy storage device and protect it from environmental influences. Furthermore, energy storage enclosures can include interfaces for transferring electrical energy between individual batteries or to an electrical load.

[0005] DE 10 2017 216 782 A1 discloses a module housing for a vehicle battery, comprising a receiving element with a U-shaped cross-section for accommodating a battery module. The receiving element is closed off at the opposite end faces by a plate. The plates are connected to the receiving element via a tension band.

[0006] Based on this, the present invention is based on the object of providing a housing, in particular for an energy storage device, that enables simplified assembly.

[0007] To achieve the object, a housing, in particular for an energy storage device, is proposed, comprising: an intermediate unit with an intermediate element in the form of a prism with an H-shaped base area and a longitudinal axis, wherein the intermediate element has a first side wall on a first longitudinal side and a second side wall on a second longitudinal side, between which a support section extends which spans a support plane, and a closing unit, wherein the intermediate element is connected to the closing unit at a first end of the first side wall and the second side wall remote from the support section in such a way that a first housing chamber is formed between the intermediate unit and the closing unit.

[0008] By connecting the termination unit to the remote ends of the first and second side walls and the H-shaped design of the intermediate unit, accessibility to the energy storage unit and the interfaces provided for the operation of the energy storage unit is increased during assembly.

[0009] A prism, within the meaning of this invention, is a geometric body described by the parallel displacement of a flat polygon along a longitudinal axis not lying in this plane. A prism is produced, for example, by extrusion through a polygonal-forming opening. In this respect, the intermediate element can be produced by extrusion or extrusion. An intermediate element in the form of a prism, within the meaning of this invention, should also be understood to mean that the intermediate element has a prismatic basic shape that includes subsequently introduced machining, so that the intermediate element is prismatic at least in sections. In this respect, the intermediate element can be produced by extrusion or extrusion and have subsequent machining.

[0010] The longitudinal sides of the intermediate element are understood to be those sides of the intermediate element that are arranged parallel to the longitudinal axis. Accordingly, the end faces of the intermediate element are arranged transversely to the longitudinal axis and also to the longitudinal axes. Accordingly, the end faces can also be referred to as transverse sides.

[0011] The supporting section spans the supporting plane in such a way that the supporting plane passes through the geometric center of gravity of the cross-sectional area of ​​the supporting section.

[0012] In one possible embodiment, the first end of the first side wall remote from the support section can have a first terminating contact surface that is connected to the terminating unit. Alternatively or in combination, a first end of the second side wall remote from the support section can have a second terminating contact surface that is connected to the terminating unit. The first terminating contact surface and the second terminating contact surface can lie in a terminating contact plane. The connection between the first end of the side walls and the terminating unit can be direct, at least in sections, so that the first end of the respective side wall is in contact with the terminating unit.Alternatively, the connection between the first end of the side walls and the end unit can be made indirectly, at least in sections, wherein a seal can be provided in particular between the first end of the side walls and the end unit.

[0013] In another possible embodiment, the intermediate element can be connected to a receiving unit at a second end of the first side wall and the second side wall opposite the first end. A second housing chamber can be formed between the intermediate unit and the receiving unit.

[0014] Furthermore, the second end of the first side wall can have a first receiving contact surface that is connected to the receiving unit. Alternatively or in combination, the second end of the second side wall can have a second receiving contact surface that is connected to the receiving unit. In this case, the first receiving contact surface and the second receiving contact surface can lie in a receiving contact plane. The connection between the second end of the side walls and the receiving unit can be made directly, at least in sections, so that the second end of the respective side wall is in contact with the receiving unit. Alternatively, the connection between the second end of the side walls and the receiving unit can be made indirectly, at least in sections, wherein a seal can be provided in particular between the second end of the side walls and the receiving unit.The terminating contact plane and the supporting plane can be arranged parallel and spaced apart by a first amount, and / or the receiving contact plane and the supporting plane can be arranged parallel and spaced apart by a second amount. In this case, the ratio of the first amount to the second amount can be at least 0.25, in particular at least 0.3. Alternatively or in combination, the ratio of the first amount to the second amount can be less than or equal to 4, in particular less than or equal to 3.

[0015] In one possible embodiment, the support section can comprise a channel that runs parallel to the longitudinal axis, at least in sections. The channel can comprise a first channel section having an inlet opening at an inlet end and a further channel section having an outlet opening at an outlet end, wherein the first channel section is fluidly connected at a connecting end to a connecting end of the further channel section.

[0016] Furthermore, the first channel section can comprise an inlet collecting section adjacent to the inlet opening and a connecting collecting section at the connecting end. The second channel section can comprise an outlet collecting section adjacent to the outlet opening and a connecting collecting section at the connecting end. In this case, it is possible for the connecting collecting section of the first channel section to be fluidically connected to the connecting collecting section of the further channel section and, in particular, to be designed integrally therewith. In particular, it is conceivable for the inlet collecting section and / or the connecting collecting section of the first channel section to be formed by a recess in the first channel section; and / or for the outlet collecting section and / or the connecting collecting section of the further channel section to be formed by a recess in the further channel section.The recesses in the first and the further channel sections can each be produced by inserting a finger milling cutter into the respective channel section. In particular, the finger milling cutter can be aligned such that the longitudinal axis of the finger milling cutter is parallel to the longitudinal axis of the prism.

[0017] In a further possible embodiment, the intermediate unit can comprise a first cover element and a second cover element. In this case, the first cover element can be connected to the intermediate element at a first end face of the intermediate element, and the second cover element can be connected to the intermediate element at a second end face opposite the first end face. In particular, a first end of the first cover element remote from the support section can have a third terminating contact surface that is connected to the terminating unit; and a first end of the second cover element remote from the support section can have a fourth terminating contact surface that is connected to the terminating unit. In this case, the third terminating contact surface and the fourth terminating contact surface can lie in the common terminating contact plane.The connection between the first end of the cover elements and the closure unit can be made directly, at least in sections, so that the first end of the respective cover element is in contact with the closure unit. Alternatively, the connection between the first end of the cover elements and the closure unit can be made indirectly, at least in sections, wherein a seal can be provided, in particular, between the first end of the cover elements and the closure unit. In particular, the third closure contact surface and the fourth closure contact surface, together with the first closure contact surface and the second closure contact surface, can form an annular closure contact surface.

[0018] Furthermore, a second end of the first cover element remote from the support section can have a third receiving contact surface that is connected to the receiving unit. A second end of the second cover element remote from the support section can have a fourth receiving contact surface that is connected to the receiving unit. In this case, the third receiving contact surface and the fourth receiving contact surface can lie in the receiving contact plane. The connection between the second end of the cover elements and the receiving unit can be made directly, at least in sections, so that the second end of the respective cover element is in contact with the receiving unit. Alternatively, the connection between the second end of the cover elements and the receiving unit can be made indirectly, at least in sections, wherein a seal can be provided in particular between the second end of the cover elements and the receiving unit.In particular, the third receiving contact surface and the fourth receiving contact surface can form an annular receiving contact surface with the first receiving contact surface and the second receiving contact surface.

[0019] Furthermore, one of the first cover element and the second cover element can comprise an inlet opening that directly adjoins and merges into the inlet opening of the channel. Alternatively or in combination, one of the first cover element and the second cover element can also comprise an outlet opening that directly adjoins and merges into the outlet opening of the channel. In this case, the inlet opening and the outlet opening can each be intersected by the support plane and arranged outside the terminating contact plane and the receiving contact plane.

[0020] Furthermore, the first cover element and / or the second cover element can comprise a first weld opening and a second weld opening, each of which is arranged in overlap with the support section. The channel can be arranged between the first weld opening and the second weld opening in a projection in the direction of the longitudinal axis.

[0034] Figure 14 is a side view of the housing of Figure 13; and

[0035] Figure 15 is a cross-section through the housing of Figure 13.

[0036] Figures 1 to 12, which are described together below, show a housing 1 according to the invention in a first embodiment. The housing 1 in the first embodiment comprises exactly one intermediate unit 2, a closing unit 52 and a receiving unit 63. The closing unit 52 is connected to the intermediate unit 2 by means of screws distributed over the circumference, so that a first housing chamber 84 is formed between the closing unit 52 and the intermediate unit 2. The receiving unit 63 is connected to the intermediate unit 2 by means of screws distributed over the circumference, so that a second housing chamber 85 is formed between the receiving unit 63 and the intermediate unit 2. A first energy store 87 is accommodated in the first housing chamber 84. A second energy store 88 is accommodated in the second housing chamber 85.

[0037] The intermediate unit 2 comprises an intermediate element 3 having a prismatic basic shape, with an H-shaped base surface 4 extending along a longitudinal axis 5. The intermediate element 3 is designed as an extruded profile with machining and can be made, in particular, of aluminum. The intermediate element 3 comprises a first side wall 6 and a second side wall 11, which are arranged parallel to one another. A flat support section 16 extends between the first side wall 6 and the second side wall 11. The first side wall 6 and the second side wall 11 are thus connected to one another via the support section 16. The support section 16 spans a support plane E_T. The center of gravity of a cross-section 15 with respect to the longitudinal axis 5 through the support section 16 lies in the support plane E_T.

[0038] A first end 7 of the first side wall 6, remote from the support section 16, has a thickened section that is terminated by a terminating contact surface 8. A first end 12 of the second side wall 11, remote from the support section 16, has a thickened section that is terminated by a terminating contact surface 13. The terminating contact surface 8 of the first end 7 of the first side wall 6 and the terminating contact surface 13 of the first end 12 of the second side wall 11 lie in a common terminating contact plane E_AB. The terminating contact plane E_AB is arranged parallel to the support plane E_T and spaced from it by the first amount D1.

[0039] A second end 9 of the first side wall 6, remote from the support section 16, has a thickened section that is terminated by a receiving contact surface 10. A second end 14 of the second side wall 11, remote from the support section 16, has a thickened section that is terminated by a receiving contact surface 15. The receiving contact surface 10 of the second end 9 of the first side wall 6 and the receiving contact surface 15 of the second end 14 of the second side wall 11 lie in a common 9

[0040] Supporting contact plane E_AUF. The supporting contact plane E_AUF is arranged parallel to the supporting plane E_T and offset from it by the second amount D2.

[0041] In the present case, the amounts D1 and D2 are identical. The ratio of the first amount D1 to the second amount D2 is thus 1. However, it is also conceivable that the said ratio is at least 0.25, in particular at least 0.3, and / or less than or equal to 4, in particular less than or equal to 3.

[0042] The intermediate unit 2 comprises a first cover element 36 and a second cover element 41. The first cover element 36 is firmly connected to the intermediate element 3 at a first end face of the intermediate element 3. The second cover element 41 is firmly connected to the intermediate element 3 at the opposite second end face. The firm connection between the first cover element 36 or the second cover element 41 and the intermediate element 3 is here implemented by a weld seam, the course of which is described in detail below. Alternatively, it is also conceivable for the firm connection between the elements to be established by a detachable connection, for example by screws. The first cover element 36 and the second cover element 41, together with the intermediate element 3, form a first half-shell open in the direction of the closing unit and a second half-shell open in the direction of the receiving unit.

[0043] A first end 37 of the first cover element 36, remote from the support section 16, has a third terminating contact surface 38. A first end 42 of the second cover element 41, remote from the support section 16, has a fourth terminating contact surface 43. The third terminating contact surface 38 and the fourth terminating contact surface 43 lie in the terminating contact plane E_AB. The first terminating contact surface 8, the second terminating contact surface 13, the third terminating contact surface 38, and the fourth terminating contact surface 43 form an annular terminating contact surface 46 of the intermediate unit 2.

[0044] A second end 39 of the first cover element 36, remote from the support section, has a third receiving contact surface 40. A second end 44 of the second cover element 41, remote from the support section 16, has a fourth receiving contact surface 45. The third receiving contact surface 40 and the fourth receiving contact surface 45 lie in the receiving contact plane E_AUF. The first receiving contact surface 10, the second receiving contact surface 15, the third receiving contact surface 40, and the fourth receiving contact surface 45 together form an annular receiving contact surface 47 of the intermediate unit 2.

[0045] Cables or piping can extend from the first housing chamber 84 into the second housing chamber 85 via openings 93 in the support sections 16 of the intermediate elements 3.

[0046] The termination unit 52 comprises a termination element 53 having a prismatic basic shape with a U-shaped base. The termination element 53 has a first side wall 56 arranged parallel to a second side wall 59. A flat termination section 62 extends between the first side wall 56 and the second side wall 59. At an end 57 of the first side wall 56 remote from the termination section 62, a widened section is provided which is delimited by a first termination contact surface 58. At an end 60 of the second side wall 59 remote from the termination section 62, a widened section is provided which is delimited by a second termination contact surface 61.

[0047] The closing unit 52 comprises a first cover element 78 and a second cover element 81. The first cover element 78 is firmly connected to the closing element 53 on a first end face of the closing element 53. The second cover element 81 is firmly connected to the closing element 53 on a second, opposite end face of the closing element 53. The firm connection between the first cover element 78 or the second cover element 81 and the closing element 53 is here implemented by a weld seam. Alternatively, it is also conceivable for the firm connection between the elements to be established by a detachable connection, for example by screws. The first cover element 78 and the second cover element 81, together with the closing element 53, form a half-shell that is open in the direction of the intermediate unit 2.

[0048] An end 79 of the first cover element 78 remote from the end section 62 has a third terminating contact surface 80. An end 82 of the second cover element 81 remote from the end section 62 has a fourth terminating contact surface 83. The third terminating contact surface 80 and the fourth terminating contact surface 83 lie in the terminating contact plane E_AB.

[0049] The first terminating contact surface 58, the second terminating contact surface 61, the third terminating contact surface 80 and the fourth terminating contact surface 83 of the terminating unit 52 form an annular terminating contact surface 46' of the terminating unit 52.

[0050] The end contact surface 46 of the intermediate unit 2 and the end contact surface 46' of the end unit 52 are connected to each other via a circumferential seal (not shown). For this purpose, screw connections are provided between the intermediate unit 2 and the end unit 52, which are distributed around the circumference.

[0051] The receiving unit 63 comprises a receiving element 64 which has a prismatic basic shape with a U-shaped base. The receiving element 64 has a first side wall 65 which is arranged parallel to a second side wall 68. A flat end section 71 extends between the first side wall 65 and the second side wall 68. At an end 66 of the first side wall 65 remote from the end section 71, a widened section is provided which is delimited by a first receiving contact partial surface 67. At an end 69 of the second side wall 68 remote from the end section 71, a widened section is provided which is delimited by a second receiving contact partial surface 70.

[0052] The receiving unit 63 comprises a first cover element 72 and a second cover element 75. The first cover element 72 is firmly connected to the receiving element 64 at a first end face of the receiving element 64. The second cover element 75 is firmly connected to the receiving element 64 at a second, opposite end face of the receiving element 64. The firm connection between the first cover element 72 or the second cover element 75 and the receiving element 64 is here implemented by a weld seam. Alternatively, however, it is also conceivable for the firm connection between the elements to be detachable, for example by screwing. The first cover element 72 and the second cover element 75, together with the receiving element 64, form a half-shell that is open in the direction of the intermediate unit 2.

[0053] An end 73 of the first cover element 72 remote from the end section 71 has a third receiving contact surface 74. An end 76 of the second cover element 75 remote from the end section 71 has a fourth receiving contact surface 77. The third receiving contact surface 74 and the fourth receiving contact surface 77 lie in the receiving contact plane E_AUF. The first receiving contact surface 40, the second receiving contact surface 45, the third receiving contact surface 74, and the fourth receiving contact surface 77 of the receiving unit 63 form an annular receiving contact surface 47' of the receiving unit 63.

[0054] The receiving contact surface 47 of the intermediate unit 2 and the receiving contact surface 47' of the receiving unit 63 are connected to each other via a circumferential seal (not shown). For this purpose, screw connections are provided between the intermediate unit 2 and the receiving unit 63.

[0055] A channel 17 is integrated into the support section 16. The channel 17 comprises a first channel section 18, a second channel section 19, a third channel section 20 and a fourth channel section 21, which each extend parallel to the longitudinal axis 5 and are fluidically connected to one another. The first channel section 18 is delimited by a first boundary wall 22 and a first partition wall 23. The second channel section 19 is delimited by the first partition wall 23 and a second partition wall 23'. The third channel section 20 is delimited by the second partition wall 23' and a third partition wall 23". The fourth channel section 21 is delimited by the third partition wall 23" and a second boundary wall 22'. In the present case, the four channel sections 18, 19, 20, 21 are designed with identical widths.However, it is also conceivable that the channel sections 18, 19, 20, 21 are designed with different widths in order, for example, to optimize the flow behavior of coolant.

[0056] A dividing rib 24 is arranged in each of the four channel sections 18, 19, 20, and 21, extending parallel to the longitudinal axis 5. The dividing ribs 24 thus divide the four channel sections 18, 19, 20, and 21 into two channel sections. In the present case, the channel sections are designed with identical widths. However, it is also conceivable for the channel sections to be designed with different widths, for example, to optimize the flow behavior of the coolant.

[0057] The channel 17 comprises an inlet opening 26 at an inlet end 25. The inlet end 25 is formed by the first channel section 18. The channel 17 comprises an outlet opening 28 at an outlet end 27. The outlet end 27 is formed by the fourth channel section 21. The inlet opening 26 is fluidically connected to the outlet opening 28 via the four channel sections 18, 19, 20, 21. The first cover element 36 comprises an inlet opening 48, which directly adjoins the inlet opening 26 of the channel 17 and merges into it. Coolant can thus be supplied to the channel 17 via the inlet opening 48. For this purpose, connection means for external lines can be provided in the inlet opening 48. To optimize flow, the inlet opening 48 is essentially conical, with the cone widening towards the inlet opening 26 of the channel 17.

[0058] The first cover element 36 also includes an outlet aperture 49, which directly adjoins and merges with the outlet opening 28 of the channel 17. Coolant can thus be removed from the channel 17 via the outlet aperture 49. For this purpose, connection means for external lines can be provided in the outlet aperture 49. To optimize flow, the outlet aperture 49 is essentially conical, with the cone widening toward the outlet opening 28.

[0059] The inlet opening 48 and the outlet opening 49 are fluidically connected to one another via the channel 17. The inlet opening 48 and the outlet opening 49 are arranged such that they are each intersected by the support plane E_T. In other words, the inlet opening 48 and the outlet opening 49 lie at least partially in the support plane E_T. The inlet opening 48 and the outlet opening 49 are arranged outside the terminating contact plane E_AB and the receiving contact plane E_AUF.

[0060] The first channel section 18 comprises an inlet collection section 31 adjacent to the inlet opening 26 and a connection collection section 32 at a connection end 29. The second channel section 19 comprises a connection collection section 32' at one end, which merges into the connection collection section 32 of the first channel section 18. The second channel section 19 comprises a connection collection section 33 at a further end. The third channel section 20 comprises a connection collection section 33' at one end 10, which merges into the connection collection section 33 of the second channel section 19. The third channel section 20 comprises a connection collection section 34 at a further end. The fourth channel section 21 comprises a connection collection section 34' at a connection end 30, which merges into the connection collection section 34 of the third channel section 20.The fourth channel section 21 comprises an outlet collecting section 35 adjacent to the outlet opening 28.

[0061] The inlet collecting section 31, the connecting collecting sections 32, 32', 33, 33', 34, 34', and the outlet collecting section 35 are each formed by recesses in the channel 17. In the respective regions of the collecting sections, the partition walls 23, 23', 23" and the dividing ribs 24, 24', which extend from one end face of the intermediate element 3 to the other end face in a semi-finished state of the intermediate element 3, are removed. This can be done, for example, by means of a milling cutter inserted into the channel 17.

[0062] As can be seen particularly in Figure 7, in which the flow paths of coolant between the inlet opening 26 and the outlet opening 28 are schematically illustrated with dash-dotted arrows, the coolant meanders back and forth between the two end faces of the intermediate element 3. Due to the even number of channel sections, the coolant enters the channel 17 on the same end face of the intermediate element 3 through the inlet opening 26 as it exits through the outlet opening 28. It is understood that the number of channel sections can be freely selected, whereby in particular an odd number of channel sections can realize the outlet of the coolant on the opposite end faces of the intermediate element 3.

[0063] Figures 8 to 12 explain the course of the weld seam between the intermediate element 3 and the cover elements 36, 37 of the intermediate unit 2. The corresponding explanations apply analogously to the connection of the closing element 53 to the cover elements 78, 81 of the closing unit 52 and to the connection of the receiving element 64 to the cover elements 72, 75 of the receiving unit 63.

[0064] A main weld seam runs along the outer circumferential edge of the base surface 4 or end face of the intermediate element 3 shown in Figures 8 and 10. The base surface 4 is shown hatched in Figures 8 and 10 for the sake of clarity. The main weld seam thus describes a substantially H-shaped surface which corresponds to the end face or base surface of the intermediate element 3. In other words, the main weld seam delimits a substantially H-shaped surface which corresponds to the end face or base surface of the intermediate element. By welding the intermediate element 3 to the first cover element 36 on one end face and the second cover element 41 on the opposite end face 20, each with the main weld seam, a secure connection between the intermediate element 3 and the two cover elements can be ensured.On the other hand, the first half-shell of the intermediate unit 2, which is open in the direction of the closing unit 2, and the second half-shell of the intermediate unit 2, which is open in the direction of the receiving unit 63, can be sealed against each other by means of the welding mentioned.

[0065] In addition, two further auxiliary welds are provided between the intermediate element 3 and the respective cover element. For this purpose, for example, a first weld opening 50 and a second weld opening 51 are provided in the first cover element 36, which extend at least over the thickness of the support section 16. An auxiliary weld seam can thus be provided in each of the first weld opening 50 and the second weld opening 51, which connects an upper section of the main weld seam with a lower section of the main weld seam. The two auxiliary welds, together with the main weld seam, frame the channel 17, thus ensuring an effective seal of the channel 17. For this purpose, the first weld opening 50 and the second weld opening 51 are arranged such that, in a projection along the longitudinal axis 5, the channel 17 lies completely between them.The welding of the intermediate element 3 to the first cover element 36 on one end face and to the second cover element 41 on the opposite end face, each with the combination of main weld seam and auxiliary weld seams, can thus ensure a seal of the channel 17 with respect to the first half-shell of the intermediate unit 2 opened in the direction of the closing unit 52 and the second half-shell of the intermediate unit 2 opened in the direction of the receiving unit 63.

[0066] Figures 13 to 15, which are described together below, show a second embodiment of a housing 1' according to the invention. The second embodiment differs from the first embodiment essentially in that a second intermediate unit 2' is provided between the first intermediate unit 2 and the receiving unit 63. Regarding the similarities, reference is made to the explanation of the first embodiment for the second embodiment. Identical or corresponding elements are designated by the same reference numerals.

[0067] The housing 1' comprises a first intermediate unit 2 and a second intermediate unit 2', a termination unit 52 and a receiving unit 63. The termination unit 52 is connected to the first intermediate unit 2 via screws, so that a first housing chamber 84 is formed between the termination unit 52 and the first intermediate unit 2. The first intermediate unit 2 is connected to the second intermediate unit 2', so that a second housing chamber 85 is formed between the first intermediate unit 2 and the second intermediate unit 2'. The second intermediate unit 2' is connected to the receiving unit 63, so that a third housing chamber 86 is formed between the second intermediate unit 2 and the receiving unit 63. A first energy storage device 87 is arranged in the first housing chamber 84. A second energy storage device 88 is arranged in the second housing chamber 85. A third energy storage device 89 is arranged in the third housing chamber 86.It will thus be apparent to the person skilled in the art that the housing 1 has a modular design and can be expanded with additional intermediate units 2. Each additional intermediate unit represents a receiving unit for the intermediate unit above it.
