Description

Technical Field

[0001] This invention relates to the technical field of energy storage units and associated components. In particular, it relates to high-performance energy storage units that can provide electrical energy for powering mobile vehicles. Background Technology

[0002] Various solutions have been proposed to improve the efficiency and range of fully or partially electric motorized vehicles.

[0003] Efforts are being made to design the temperature regulation, and especially the cooling, of electrochemical energy storage units or modules so that this consumes as little energy as possible without unnecessarily increasing the mass of the vehicle. This allows a higher proportion of the energy that can be stored in the energy storage unit to be directly used to power the lightest possible vehicle.

[0004] Efforts are also being made to provide electrochemical energy storage units or modules in the most compact possible configuration, so that as much space as possible in a mobile vehicle can be used for loading.

[0005] In addition, the center of gravity of motor vehicles should be as low as possible, as this can increase driving safety, especially when it is necessary to avoid suddenly appearing obstacles at high speeds.

[0006] There is still a great need for improvement in this regard. Summary of the Invention

[0007] The object of the present invention is to provide efficient energy storage units and / or components thereof in the simplest possible manner.

[0008] According to the present invention, this objective is achieved by an energy storage unit according to the relevant independent claims.

[0009] Energy storage units can be, in particular, energy storage modules.

[0010] The term "especially" is used within the scope of this specification and the appended claims to describe possible selected and / or optional features.

[0011] Energy storage units can be used to provide electrical energy for powering mobile vehicles.

[0012] Multiple energy storage units, such as multiple energy storage units according to the invention, can be interconnected to form an energy storage device or energy storage system, which can provide all the electrical energy for driving a mobile vehicle. In this case, the energy storage unit according to the invention can in particular provide a portion of the electrical energy for driving the mobile vehicle.

[0013] The energy storage unit comprises multiple energy storage elements. These are preferably multiple electrochemical energy storage elements, such as multiple battery cells. The battery cells may be, for example, rechargeable lithium-ion battery cells.

[0014] The energy storage elements that may be included in the energy storage unit can be energy storage elements that are typically installed in energy storage devices commonly used to drive motorized vehicles. These are generally known and therefore should not be discussed in detail.

[0015] In particular, three different types of battery cells are installed in energy storage units that can provide electrical energy for powering motorized vehicles. In this case, they are cylindrical battery cells, prismatic battery cells, and pouch cells.

[0016] The battery cell can preferably be a cylindrical battery cell, a prismatic battery cell, or a pouch cell, and is particularly preferably a cylindrical battery cell or a prismatic battery cell, such as a cylindrical battery cell.

[0017] When referring to energy storage devices, this article specifically refers to rechargeable energy storage devices.

[0018] The energy storage unit includes a temperature-regulating fluid barrier.

[0019] A temperature-regulating fluid barrier extends around the temperature-regulating space. Within this space, at least multiple energy storage elements can be temperature-regulated using the temperature-regulating fluid.

[0020] Multiple energy storage elements refer to multiple energy storage elements included in an energy storage unit. The multiple energy storage elements included in an energy storage unit can be 5% to 100% of the energy storage elements included in the energy storage unit, preferably 40% to 100% of the energy storage elements included in the energy storage unit, and particularly preferably 75% to 100% of the energy storage elements included in the energy storage unit.

[0021] One particular advantage is that all energy storage elements included in the energy storage unit can be temperature-controlled in the temperature-controlled space using a temperature-controlled fluid.

[0022] The structure and materials of the temperature-regulating fluid barrier for the energy storage unit are not defined. The temperature-regulating fluid barrier can be constructed as a single piece or multiple pieces, preferably multiple pieces, such as three pieces.

[0023] Advantageously, the temperature-regulating fluid barrier has at least one first barrier element and at least one second barrier element.

[0024] Advantageously, at least one first barrier element and at least one second barrier element form a temperature-regulating fluid barrier.

[0025] Advantageously, the first barrier element can form a covering element, such as a cover element, of the temperature-regulating fluid barrier.

[0026] Advantageously, the second barrier element can form a covering element, such as a bottom element, of the temperature-regulating fluid barrier.

[0027] Preferably, the third barrier element can form a frame wall element of the temperature-regulating fluid barrier. The frame wall element can be a frame and extends around the temperature-regulating space.

[0028] It is particularly advantageous that the temperature-regulating fluid barrier has a barrier region. The barrier region may be, for example, a wall region. Preferably, the barrier region may be reinforced by means of a reinforcing element.

[0029] The barrier region reinforced by the reinforcing element can preferably be a barrier region formed by the first barrier element or the second barrier element.

[0030] One particularly advantageous feature is that the reinforcing element strengthens the barrier area to prevent it from bending outwards.

[0031] Reinforcing elements can strengthen the barrier area, for example, to prevent the barrier area from bulging out.

[0032] The protrusion of the barrier zone can specifically mean that the barrier zone arches outward or the arching outward is enhanced. The outward bending or arching of the barrier zone can specifically refer to the fact that at the point where the barrier zone bends or arches outward, the barrier zone is bent, resulting in an increase or expansion of the temperature control space.

[0033] One particularly advantageous aspect is that the reinforcing element extends from the barrier region into the temperature regulation space.

[0034] It is particularly advantageous that the barrier region is a first barrier region, and the temperature-regulating fluid barrier has a second barrier region. The first barrier region may be, for example, a first wall region. The second barrier region may be, for example, a second wall region.

[0035] The reinforcing element may preferably extend from the first barrier region to the second barrier region.

[0036] It is particularly advantageous that the first barrier zone and the second barrier zone are the opposing barrier zones of the temperature-regulating fluid barrier.

[0037] For example, the first barrier region and the second barrier region can be opposing barrier regions of a temperature-regulating fluid barrier. Advantageously, the first wall region and the second wall region can be opposing wall regions of a temperature-regulating fluid barrier.

[0038] Preferably, the first wall region may be a wall region formed by a first barrier element, such as a cover element. Preferably, the second wall region may be a wall region formed by a second barrier element, such as a bottom element.

[0039] It is particularly advantageous that the reinforcing element extends from the first wall region formed by the cover element to the second wall region formed by the bottom element.

[0040] Advantageously, the reinforcing element is arranged such that the protrusion of the barrier region, such as the first barrier region or the second barrier region, is accompanied by a tensile load on the reinforcing element. Then, in particular, forces capable of resisting the protrusion can function within the reinforcing element.

[0041] Preferably, multiple energy storage elements can be arranged in a regular pattern.

[0042] In particular, the surfaces of multiple pairs of adjacent energy storage elements can be in contact with each other, or the spacing between two adjacent energy storage elements in multiple pairs of adjacent energy storage elements can be the same. It is particularly advantageous that the spacing of the adjacent positioning areas of the separating element, such as the molding element, determines the spacing of the adjacent energy storage elements. The separating element, such as the molding element, described herein can surround the adjacent energy storage elements.

[0043] In particular, the states (Lage) of the corresponding multiple energy storage elements can respectively define two parallel planes, between which the corresponding multiple energy storage elements are arranged.

[0044] In particular, the position of adjacent energy storage elements can be approximated by a prism. Preferably, the edges extending along the sides of the prism coincide with a straight line extending through the central energy storage element. For example, the position of three adjacent energy storage elements can be approximated by a triangular prism. Preferably, the three edges extending along the sides of the triangular prism coincide with a straight line extending through the central three adjacent energy storage elements.

[0045] Of course, the parallel planes, prisms, and triangular prisms mentioned are merely auxiliary tools, used only to define the regular arrangement of multiple energy storage elements.

[0046] Advantageously, the enhancement element can occupy the position of one of the energy storage elements in a regular arrangement of multiple energy storage elements. In particular, the enhancement element can then replace one of the energy storage elements in the regular arrangement.

[0047] Advantageously, the reinforcing element extends between multiple energy storage elements in a regular arrangement of the elements. Preferably, the reinforcing element extends through the prism. For example, it may extend at least from the bottom surface of the prism to the top surface. For example, it may extend into the prism via the bottom surface, through the prism, and out of the prism via the top surface.

[0048] It is particularly preferred that the longitudinal axis of the reinforcing element is parallel to the edge of the prism that extends along the side of the prism.

[0049] Preferably, the reinforcing element may include paired reinforcing elements. Paired reinforcing elements may be, for example, support reinforcing elements.

[0050] It is particularly preferred that the reinforcing element also serves as a mating reinforcing element or a supporting reinforcing element.

[0051] Paired reinforcing elements or support reinforcing elements can strengthen the barrier area to prevent it from bending inward. Paired reinforcing elements or support reinforcing elements can strengthen the barrier area, for example, to prevent the barrier area from concave.

[0052] The concave movement can be, in particular, the reverse movement of the convex movement as described in this paper.

[0053] Advantageously, the mating reinforcement element can extend from the first barrier region to the second barrier region. For example, it can extend from the first barrier region to the second barrier region.

[0054] Advantageously, the end of the reinforcing element may extend into the recess of the barrier region. For example, the first end of the reinforcing element may extend into the first recess of the first barrier region.

[0055] Preferably, the second end of the reinforcing element extends into the second recess of the second barrier region. The terms "first" and "second" indicate only that the recess is respectively designated as the "first" barrier region or the "second" barrier region. Mentioning the "first" recess does not imply that the "first" barrier region must necessarily have other recesses. Mentioning the "second" recess does not imply that the second barrier region must necessarily have other recesses.

[0056] Preferably, the reinforcing element can be secured, preferably secured in a material-fit manner, particularly preferably welded or glued, for example welded to the first barrier area and the second barrier area.

[0057] It may be particularly advantageous that the first end of the reinforcing element is secured in a material-fit manner, preferably by welding or bonding, for example by welding; and / or the second end of the reinforcing element is secured in a material-fit manner, preferably by welding or bonding, for example by welding.

[0058] For example, the first end of the reinforcing element may be secured in a material-fit manner, preferably by welding or bonding, for example by welding into the first recess; and / or the second end of the reinforcing element may be secured in a material-fit manner, preferably by welding or bonding, for example by welding into the second recess.

[0059] Advantageously, the reinforcing element includes a securing element that can secure the mating reinforcing element in the barrier region. The mating reinforcing element can be secured, for example, in a recess in the barrier region using the securing element.

[0060] Reinforcing elements may include stabilizing elements.

[0061] The securing element may preferably have threads. The securing element may be, for example, a screw, bolt, or nut.

[0062] Advantageously, the reinforcing element has a shoulder area, a neck area, and a head area.

[0063] Preferably, the barrier area extends into the support area, which is located in the neck area between the shoulder area and the head area.

[0064] It is particularly advantageous that the securing element forms the head region, and the mating reinforcing element forms the shoulder region. When the securing element is a screw, the head of the screw can form the head region. When the securing element is a nut, the nut can form the head region.

[0065] Advantageously, the reinforcing elements may have threads that engage with each other.

[0066] It is particularly advantageous that the mating reinforcement element and the securing element have threads that engage with each other.

[0067] It is particularly advantageous that the reinforcing element is attached to the barrier area.

[0068] The reinforcing element may be attached to the barrier area, for example, by force, by shape and / or by material.

[0069] Preferably, the end of the reinforcing element or the paired reinforcing element extends into the recess of the barrier region and is attached thereto at the barrier region.

[0070] For example, the first end of the reinforcing element or the mating reinforcing element may extend into the first recess of the first barrier region and be attached thereto at the first barrier region.

[0071] Of course, an energy storage unit can include multiple enhancement elements. The barrier zone can be enhanced using multiple enhancement elements.

[0072] For example, the reinforcing element may be a first reinforcing element, and the energy storage unit may include at least one other reinforcing element, such as multiple other reinforcing elements. Advantageously, the first reinforcing element and at least two, preferably at least four, particularly preferably at least six, such as at least eight other reinforcing elements may extend from the first barrier region to the second barrier region.

[0073] Advantageously, the temperature-regulating space extends around one or more of the reinforcing elements, which extends from a first barrier region to a second barrier region. For example, the first temperature-regulating region described herein may extend around a segment of each of the reinforcing elements, and the second temperature-regulating region described herein may extend around another segment of each of the reinforcing elements, with the temperature-regulating space extending around the reinforcing element.

[0074] Advantageously, the total cross-sectional area of ​​all reinforcing elements extending around the temperature-regulating space and from the first barrier region to the second barrier region is at least 0.025%, preferably at least 0.04%, particularly preferably at least 0.06%, for example at least 0.1% of the total cross-sectional area of ​​all energy storage elements, which can be temperature-regulated in the temperature-regulating space by means of a temperature-regulating fluid.

[0077] Preferably, when comparing the total cross-sectional area, the total cross-sectional area of ​​the reinforcing element and the energy storage element is considered, namely, the total cross-sectional area obtained in the central plane of the energy storage unit's cross-section. The central plane can preferably extend centrally through the energy storage unit in a manner parallel to a first direction, such as the first direction described herein, and parallel to a second direction, such as the second direction described herein. In particular, the central plane can extend centrally through the energy storage unit orthogonal to a third direction, such as the third direction described herein.

[0078] In particular, extending centrally through the energy storage unit can mean that one half of the energy storage unit is located on one side of the central plane, and the other half of the energy storage unit is located on the other side of the central plane, with the volume of one half corresponding to the volume of the other half.

[0079] The cross-sectional area that can be attributed to a possible enclosure or housing, such as a battery cell enclosure or housing, can also be included in the total cross-sectional area of ​​the energy storage element.

[0148] It is particularly advantageous that the energy storage unit has at least one temperature-regulating fluid passage. Preferably, at least one temperature-regulating fluid passage can connect the first temperature-regulating zone and the second temperature-regulating zone in a fluid-guided manner.

[0149] At least one temperature-regulating fluid passage may preferably be located at the edge of the temperature-regulating space, particularly at the edge of the span of the temperature-regulating space that defines the temperature-regulating space along or against the second direction, such as the width extension direction.

[0152] Preferably, the inlet is arranged along the second direction between the two temperature-regulating fluid passages, wherein the temperature-regulating fluid passage with the inlet arranged therebetween can be offset relative to the inlet in the first direction.

[0153] Particularly preferred is that the inlet and outlet are respectively arranged in the second direction between the two temperature-regulating fluid passages, wherein the temperature-regulating fluid passages with the inlet and outlet arranged therebetween can be offset relative to the inlet and outlet in the first direction.

[0154] It is particularly advantageous that the energy storage unit includes a temperature-regulating fluid guiding element, wherein the temperature-regulating fluid guiding element determines the direction of the temperature-regulating fluid distribution channel or the direction of the temperature-regulating fluid collection channel.

[0155] For example, the energy storage unit may include a first temperature-regulating fluid guiding element and a second temperature-regulating fluid guiding element, wherein the first temperature-regulating fluid guiding element determines the direction of the temperature-regulating fluid distribution channel and the second temperature-regulating fluid guiding element determines the direction of the temperature-regulating fluid collection channel.

[0157] It is particularly advantageous that the fluid distribution path is constructed at the temperature-regulating fluid guiding element, which determines the direction of the temperature-regulating fluid distribution path.

[0158] It is particularly advantageous that the fluid collection passage is constructed at the temperature-controlled fluid guiding element, which determines the direction of the temperature-controlled fluid collection passage.

[0159] Advantageously, the temperature-regulating fluid guiding element can be grooved. The cross-section of the temperature-regulating fluid guiding element can be, for example, C-shaped or U-shaped.

[0160] Advantageously, the energy storage unit may include a temperature-regulating fluid guiding area. This temperature-regulating fluid guiding area may, for example, be a temperature-regulating fluid distribution area or a temperature-regulating fluid collection area.

[0161] Preferably, the energy storage unit may include a temperature-regulating fluid distribution area and / or a temperature-regulating fluid collection area.

[0162] For example, an energy storage unit may include a temperature-regulating fluid distribution area and a temperature-regulating fluid collection area.

[0163] The temperature-regulating fluid guiding zone includes a first guiding zone section and a second guiding zone section.

[0164] The first guiding area segment could be, for example, the first allocation area segment or the first collection area segment.

[0165] The second guide area segment could be, for example, the second allocation area segment or the second collection area segment.

[0166] The first distribution zone section can be, in particular, the first section of the temperature-regulating fluid distribution zone.

[0167] The first collection zone section can be, in particular, the first section of the temperature-controlled fluid collection zone.

[0168] The second distribution zone section can be, in particular, the second section of the temperature-regulating fluid distribution zone.

[0169] The second collection zone section can be, in particular, the second section of the temperature-controlled fluid collection zone.

[0170] The two guiding zones are arranged directly or indirectly in the direction of the temperature-regulating fluid flow, and the temperature-regulating fluid can be guided in the temperature-regulating fluid guiding zone in the direction of the temperature-regulating fluid flow.

[0171] Alternatively or supplemented by the following feasible method, namely, two guide zone segments are arranged directly or indirectly in the direction of temperature regulating fluid flow, the temperature regulating fluid can be guided in the temperature regulating fluid guide zone in the direction of temperature regulating fluid flow, and the two guide zone segments can be adjacent to each other or staggered from each other in a first direction, such as the length extension direction of the energy storage unit.

[0172] It is particularly advantageous that the two guide zone segments are adjacent to or staggered from each other in a first direction, which may be, for example, the length extension direction of the energy storage unit.

[0173] Preferably, the span of the first guide zone segment in the first direction is the same as the span of the second guide zone segment in the first direction.

[0174] In particular, the measurable lengths of the two guide zone segments in the first direction can be the same.

[0175] Advantageously, the temperature-regulating fluid guiding area extends through the temperature-regulating fluid guiding channel. The temperature-regulating fluid guiding channel may be, for example, the temperature-regulating fluid distribution channel or the temperature-regulating fluid collection channel described herein.

[0176] Advantageously, the temperature-regulating fluid distribution area extends through the temperature-regulating fluid distribution channel.

[0177] Advantageously, the temperature-regulating fluid collection area extends through the temperature-regulating fluid collection channel.

[0178] For example, the temperature-regulating fluid guiding channel may include a first temperature-regulating fluid guiding channel section, such as a first temperature-regulating fluid distribution channel section or a first temperature-regulating fluid collection channel section.

[0179] For example, the temperature-regulating fluid guiding channel may include a second temperature-regulating fluid guiding channel section, such as a second temperature-regulating fluid distribution channel section or a second temperature-regulating fluid collection channel section.

[0180] Advantageously, the first guide zone section extends through the first temperature-regulating fluid guide channel section.

[0181] Advantageously, the second guide zone section extends through the second temperature-regulating fluid guide channel section.

[0182] Advantageously, the temperature-regulating space has a temperature-regulating zone, such as a first temperature-regulating zone and a second temperature-regulating zone, wherein the temperature-regulating fluid guiding zone is connected to the temperature-regulating zone via one or more passages in a fluid-guiding manner, wherein the one or more passages are configured such that a second flow resistance for the transfer of the temperature-regulating fluid between the temperature-regulating zone and the second guiding zone is lower than a first flow resistance for the transfer of the temperature-regulating fluid between the temperature-regulating zone and the first guiding zone.

[0183] The lower flow resistance can be determined by allowing temperature-controlled fluid supplied at a specific pressure to flow through one or more passages in the first guide zone segment for a defined time period, and measuring the volume of temperature-controlled fluid obtained through those passages during that time period. This test is then repeated for the second guide zone segment. If more temperature-controlled fluid is obtained via the one or more passages from the second guide zone segment, the flow resistance for the transfer of temperature-controlled fluid between the temperature-controlled zone and the second guide zone segment is lower than the flow resistance for the transfer of temperature-controlled fluid between the temperature-controlled zone and the first guide zone segment. The test can preferably be performed at the temperature-controlled fluid guide element, away from the temperature-controlled space.

[0184] The pathway described in conjunction with the guide zone segment can be, for example, the fluid collection pathway or the fluid distribution pathway described in this paper.

[0185] Various feasible ways have been found to construct the one or more pathways such that the second flow resistance for the transfer of the temperature-regulating fluid between the temperature-regulating zone and the second guide zone is lower than the first flow resistance for the transfer of the temperature-regulating fluid between the temperature-regulating zone and the first guide zone.

[0186] Therefore, the pathway can be, for example, V-shaped or wedge-shaped, wherein the narrower section of the pathway extends through or into the first guide zone section, and the wider section of the pathway extends through or into the second guide zone section.

[0187] A stege can define the basic V-shaped or wedge-shaped shape of a pathway.

[0188] For example, multiple V-shaped, wedge-shaped, or trapezoidal pathways arranged successively may be arranged successively or connected to each other, wherein, in particular, the ends of at least two V-shaped, wedge-shaped, or trapezoidal pathways may face each other.

[0189] It is possible that the narrower section of the pathway extends through or into the first guide zone section, and the wider section of the pathway extends through or into the second guide zone section.

[0190] A single passage can be a wavy or any type of slot. Multiple passages can be wavy or any type of slot.

[0191] Multiple passages can be circular, such as orifices. They can be distributed along the length of the temperature-regulating fluid guide zone in the direction of or against the flow of the temperature-regulating fluid, through which the temperature-regulating fluid can be guided. They can be arranged, for example, centrally in the temperature-regulating fluid guide zone, particularly with reference to a second direction, such as the width extension direction.

[0192] The spacing of the pathways can be smaller in the second guide zone segment than in the first guide zone segment.

[0193] Alternatively, the temperature-regulating space may have temperature-regulating zones, such as a first temperature-regulating zone and a second temperature-regulating zone, wherein a temperature-regulating fluid guiding zone is connected to the temperature-regulating zone via one or more passages in a fluid-guiding manner, wherein the one or more passages are configured such that a second flow resistance for the transfer of the temperature-regulating fluid between the temperature-regulating zone and the second guiding zone section is greater than a first flow resistance for the transfer of the temperature-regulating fluid between the temperature-regulating zone and the first guiding zone section. Therefore, the passages may be V-shaped or wedge-shaped, wherein a narrower section of the passage extends through or into the second guiding zone section, and a wider section of the passage extends through or into the first guiding zone section. Connectors may divide the passages into a basic V-shaped or wedge-shaped shape. For example, multiple V-shaped, wedge-shaped, or trapezoidal passages arranged successively may be arranged successively or connected to each other, wherein, in particular, the ends of at least two V-shaped, wedge-shaped, or trapezoidal passages may face each other. It is possible that the narrower section of the pathway extends through or into the second guide zone section, and the wider section of the pathway extends through or into the first guide zone section. The spacing of the pathways may be smaller in the first guide zone section than in the second guide zone section.

[0194] At least a portion of the pathway can be arranged non-centrally, for example, offset from each other in a second direction.

[0195] The pathway can have various shapes.

[0196] At least a portion of the passage may be circular, sickle-shaped, elliptical, and / or slot-shaped.

[0197] A guide fin can be arranged in a temperature-controlled space, especially in at least one temperature-controlled zone, such as the first and / or second temperature-controlled zone.

[0198] Multiple guide fins can be arranged in a temperature-controlled space, especially in at least one temperature-controlled zone, such as the first and / or second temperature-controlled zone.

[0199] One or more guide fins can help to make the temperature-regulating fluid uniformly distributed or guided in the temperature-regulating space, preferably in one or more temperature-regulating zones, for example in the first and / or second temperature-regulating zones.

[0200] For example, the guide fins can be arranged such that the temperature-regulating fluid can be guided to the end of the temperature-regulating space away from the inlet, where a Z-shaped flow of the temperature-regulating fluid is facilitated.

[0201] At least two of the multiple pathways may vary in length, position and / or shape.

[0202] Advantageously, the temperature control space has a temperature control zone, such as a first temperature control zone and a second temperature control zone, wherein the temperature control fluid guide zone is connected to the temperature control zone via one or more passages in a fluid guiding manner, wherein the size of the passage in the first guide zone segment is smaller than the size of the same passage or other passage in the second guide zone segment, preferably a corresponding size, wherein the size can be, in particular, a diameter, such as a minimum diameter.

[0203] The minimum diameter is specifically understood as the spacing between the edges or walls of the passage that extends through the central guide path through which the temperature-regulating fluid can be guided through the passage and is smaller than all other spacings between the edges or walls of the same passage.

[0204] Advantageously, the temperature control space has a temperature control zone, such as a first temperature control zone and a second temperature control zone, wherein the temperature control fluid guiding zone is connected to the temperature control zone via one or more passages in a fluid guiding manner, wherein the first cross-section of the passage in the first guiding zone segment is smaller than the second cross-section of the same passage or other passage in the second guiding zone segment.

[0205] The first cross-section may in particular have a first cross-sectional area. The cross-sectional area may in particular be the minimum cross-sectional area of ​​the passage in the first guiding region segment.

[0206] The second cross-section may in particular have a second cross-sectional area. The cross-sectional area may in particular be the minimum cross-sectional area of ​​the same passage or other passage in the second guide zone segment.

[0207] The cross-section of the passage can extend laterally through the passage, particularly in a manner orthogonal to the flow direction, and the temperature-regulating fluid can flow through the passage in this flow direction.

[0208] Advantageously, the temperature control space has a temperature control zone, such as a first temperature control zone and a second temperature control zone, wherein the temperature control fluid guiding zone is connected to the temperature control zone via one or more passages in a fluid guiding manner, wherein the number of passages in the first guiding zone segment is less than the number of passages in the second guiding zone segment.

[0209] Advantageously, the temperature-regulating fluid guiding region has a tapering zone, wherein the temperature-regulating fluid guiding region in the tapering zone tapers in the direction of temperature-regulating fluid flow, and the temperature-regulating fluid can be guided in the temperature-regulating fluid guiding region in the direction of temperature-regulating fluid flow. Alternatively, the temperature-regulating fluid guiding region in the tapering zone can taper in the opposite direction of temperature-regulating fluid flow.

[0210] Advantageously, the temperature-regulating fluid guide region in the tapering region tapers in a second direction, which may be, for example, the width extension direction of the energy storage unit.

[0211] Advantageously, the energy storage unit may include a temperature-regulating fluid guiding element, wherein the temperature-regulating fluid guiding element determines the orientation of the temperature-regulating fluid guiding zone.

[0212] Advantageously, the energy storage unit may include barrier elements, such as covering elements, wherein the barrier elements form a barrier region defining a temperature regulation space and a channel barrier region defining a temperature regulation fluid guiding region, such as a temperature regulation fluid guiding channel.

[0213] Advantageously, the temperature-regulating fluid guiding element is fixed at the barrier element, and the temperature-regulating fluid guiding element fixed at the barrier element determines the direction of the temperature-regulating fluid guiding zone.

[0214] Advantageously, the temperature-regulating fluid guiding element and the barrier element are connected to each other in a material-matching manner.

[0215] For example, temperature-regulating fluid guiding elements and barrier elements can be welded together.

[0216] It is particularly advantageous that the temperature-regulating fluid guiding element comprises or is made of plastic material, and the barrier element comprises or is made of plastic material, and the two plastic materials are welded together.

[0217] The two plastic materials may be the same or different, and may optionally contain at least one reinforcing material, such as fiber, preferably glass fiber, carbon fiber or plastic fiber, independently of each other.

[0218] The energy storage unit may preferably include a temperature-regulating fluid distribution area, a temperature-regulating fluid collection area, a first temperature-regulating area, and a second temperature-regulating area. The energy storage unit may also preferably have one or more temperature-regulating fluid pathways as described herein. Preferably, the one or more temperature-regulating fluid pathways can connect the first temperature-regulating area and the second temperature-regulating area in a fluid-guiding manner.

[0219] It is particularly advantageous that the length of the shortest temperature-regulating path from the passage through the first temperature-regulating zone, through the temperature-regulating fluid passage into the second temperature-regulating zone, and through the second temperature-regulating zone to another passage is at most 150%, preferably at most 130%, particularly preferably at most 100%, for example at most 80%, of the maximum distance measurable between the ends of the passage in the first direction, for example, the length extension direction, the ends of the passage being offset from each other at their furthest point in the first direction, for example, the length extension direction.

[0220] Then, in particular, the length of the shortest temperature-regulating path can be measured from the passage, through which the temperature-regulating fluid distribution area is connected to the first temperature-regulating area in a fluid-guided manner. Then, in particular, the length of the shortest temperature-regulating path can be measured towards other passages, through which the temperature-regulating fluid collection area is connected to the second temperature-regulating area in a fluid-guided manner.

[0221] With minimal effort, it can be determined from the relative arrangement of the flow path and the temperature-regulating fluid path which of the multiple temperature-regulating paths is the shortest and how long the shortest temperature-regulating path is.

[0222] The maximum spacing between the farthest offset passage ends in a first direction, such as the length extension direction, is determined at the temperature-controlled fluid distribution area or at the temperature-controlled fluid collection area. If the two maximum spacings between the passage ends at the temperature-controlled fluid distribution area and at the temperature-controlled fluid collection area are different, the larger of the two spacings is decisive.

[0223] If the distance between the ends of a passage is measured in a first direction, such as the length extension direction, the distance between the two parts of the one or more passages that are furthest apart from each other in the first direction is decisive.

[0224] Preferably, the temperature-regulating fluid or at least a portion thereof can be supplied to the temperature-regulating space through an inlet via a temperature-regulating fluid distribution zone, through a first distribution zone section and a second distribution zone section, and through one or more passages.

[0225] Preferably, the temperature-regulating fluid or at least a portion thereof can be discharged from the temperature-regulating space through one or more passages, through the first collection zone section and the second collection zone section, via the temperature-regulating fluid collection zone, and through the outlet.

[0226] For example, the second guide section may be offset from the inlet to a greater extent along or against the first guide section. This is particularly applicable if either the temperature-regulating fluid guide section or the temperature-regulating fluid guide section is a temperature-regulating fluid distribution section, the first guide section is a first distribution section, and the second guide section is a second distribution section.

[0227] For example, the second guide section may be offset from the outlet to a greater extent along or against the first guide section. This is particularly applicable if either the temperature-regulating fluid guide section or the temperature-regulating fluid guide section is a temperature-regulating fluid collection section, the first guide section is a first collection section, and the second guide section is a second collection section.

[0228] Advantageously, the first temperature-regulating fluid distribution channel section is the first section of the temperature-regulating fluid distribution channel described herein.

[0229] Advantageously, the second temperature-regulating fluid distribution channel section is the second section of the temperature-regulating fluid distribution channel described herein.

[0230] Advantageously, the first temperature-regulating fluid collection channel section is the first section of the temperature-regulating fluid collection channel described herein.

[0231] Advantageously, the second temperature-regulating fluid collection channel section is the second section of the temperature-regulating fluid collection channel described herein.

[0232] Advantageously, the temperature regulation space has a first temperature regulation zone and a second temperature regulation zone, and the energy storage unit has one or more temperature regulation fluid passages, wherein the one temperature regulation fluid passage connects the first temperature regulation zone and the second temperature regulation zone in a fluid guiding manner, or the multiple temperature regulation fluid passages connect the first temperature regulation zone and the second temperature regulation zone in a fluid guiding manner.

[0233] If the temperature regulation space has a first temperature regulation zone and a second temperature regulation zone, and the energy storage unit has a temperature regulation fluid passage, wherein the temperature regulation fluid passage connects the first temperature regulation zone and the second temperature regulation zone in a fluid guiding manner, then the passage may be, for example, a passage whose length measurable in a first direction, such as the length extension direction of the energy storage unit, is at least 70%, preferably at least 80%, of the length measurable in the first direction of the energy storage unit.

[0234] The statement that a temperature-regulating fluid passage connects the first temperature-regulating zone and the second temperature-regulating zone in a fluid guiding manner, or that multiple temperature-regulating fluid passages connect the first temperature-regulating zone and the second temperature-regulating zone in a fluid guiding manner, can mean that the temperature-regulating fluid passage directly connects the first temperature-regulating zone and the second temperature-regulating zone in a fluid guiding manner, or that multiple temperature-regulating fluid passages directly connect the first temperature-regulating zone and the second temperature-regulating zone in a fluid guiding manner.

[0235] The statement that a single temperature-regulating fluid passage connects the first and second temperature-regulating zones in a fluid-guided manner, or that multiple temperature-regulating fluid passages connect the first and second temperature-regulating zones in a fluid-guided manner, can mean that the single temperature-regulating fluid passage connects the first and second temperature-regulating zones to ground in a fluid-guided manner, or that multiple temperature-regulating fluid passages connect the first and second temperature-regulating zones to ground in a fluid-guided manner. For example, the single temperature-regulating fluid passage may connect the first and second temperature-regulating zones in a fluid-guided manner via one or more other temperature-regulating zones, or multiple temperature-regulating fluid passages may connect the first and second temperature-regulating zones in a fluid-guided manner via one or more other temperature-regulating zones.

[0236] Optional additional temperature control zones can be located between the first and second temperature control zones.

[0237] Several additional optional temperature control zones can be located between the first and second temperature control zones.

[0238] Advantageously, there are no other temperature control zones between the first and second temperature control zones.

[0239] Advantageously, the temperature-regulating fluid passage or multiple temperature-regulating fluid passages may include a first through section and a second through section, wherein the first through section has the same span in a first direction, such as the length extension direction, as the second through section has the same span in the first direction, wherein the two through sections are adjacent to or offset from each other in the first direction.

[0240] Preferably, the second through section may be significantly offset from the first through section in the first direction relative to the inlet and / or outlet of the energy storage unit as described herein.

[0241] Advantageously, one or more temperature-regulating fluid passages are configured such that the second through-flow resistance of the temperature-regulating fluid from the first temperature-regulating zone to the second temperature-regulating zone in the second through-section is lower than the first through-flow resistance of the temperature-regulating fluid from the first temperature-regulating zone to the second temperature-regulating zone in the first through-section.

[0242] The flow resistance in the two through sections can be tested and compared as described in this paper for the flow resistance involving the pathway, which, in conjunction with the guide section, has already been described.

[0243] This can be advantageous because, during the operation of the energy storage unit, a lower pressure gradient can exist in the second through section compared to the first through section. The lower flow resistance of the second through section compared to the first through section can facilitate the flow of the same or nearly the same amount of temperature-regulating fluid through the second through section to the second temperature-regulating zone. The lower pressure gradient in the second through section may be due to the fact that the inlet and / or outlet are farther from the second through section than from the first through section.

[0244] Advantageously, the energy storage unit may have an inlet and an outlet as described herein, through which temperature-regulating fluid may be introduced into the energy storage unit, and through which temperature-regulating fluid may flow out of the energy storage unit, wherein a second temperature-regulating fluid guide path from the inlet through a second through section to the outlet is longer than a first temperature-regulating fluid guide path from the inlet through a first through section to the outlet.

[0245] Advantageously, the size of the temperature-regulating fluid passage in the first through section is smaller than the size of the same temperature-regulating fluid passage or other temperature-regulating fluid passage in the second through section.

[0246] Advantageously, the size of the temperature-regulating fluid passage in the first through section is smaller than the corresponding size of the same temperature-regulating fluid passage or other temperature-regulating fluid passages in the second through section.

[0247] The size can be, in particular, the diameter. The diameter can be, for example, the minimum diameter.

[0248] Advantageously, the first cross-section of the temperature-regulating fluid passage in the first through section is smaller than the second cross-section of the same temperature-regulating fluid passage or other temperature-regulating fluid passages in the second through section.

[0249] When referring to the cross-section of a temperature-regulating fluid passage in this article, this can specifically mean the cross-sectional area of ​​the temperature-regulating fluid passage, especially the cross-sectional area at the narrowest part of the temperature-regulating fluid passage.

[0250] Advantageously, the first cross-sectional area of ​​the temperature-regulating fluid passage in the first through section is smaller than the second cross-sectional area of ​​the same temperature-regulating fluid passage or other temperature-regulating fluid passages in the second through section.

[0251] Advantageously, the first cross-sectional area of ​​the temperature-regulating fluid passage at the narrowest point in the first through section is smaller than the second cross-sectional area at the narrowest point of the same temperature-regulating fluid passage or other temperature-regulating fluid passages in the second through section.

[0252] Alternatively, the one or more temperature-regulating fluid passages can be configured such that the second through-flow resistance of the temperature-regulating fluid from the first temperature-regulating zone to the second temperature-regulating zone in the second through-section is greater than the first through-flow resistance of the temperature-regulating fluid from the first temperature-regulating zone to the second temperature-regulating zone in the first through-section. Advantageously, the size of the temperature-regulating fluid passage in the first through-section is larger than the size of the same temperature-regulating fluid passage or other temperature-regulating fluid passages in the second through-section. Advantageously, the size of the temperature-regulating fluid passage in the first through-section is larger than the corresponding size of the same temperature-regulating fluid passage or other temperature-regulating fluid passages in the second through-section. Advantageously, the first cross-section of the temperature-regulating fluid passage in the first through-section is larger than the second cross-section of the same temperature-regulating fluid passage or other temperature-regulating fluid passages in the second through-section. Advantageously, the first cross-sectional area of ​​the temperature-regulating fluid passage in the first through-section is larger than the second cross-sectional area of ​​the same temperature-regulating fluid passage or other temperature-regulating fluid passages in the second through-section. Advantageously, the first cross-sectional area of ​​the temperature-regulating fluid passage at the narrowest point in the first through section is greater than the second cross-sectional area at the narrowest point of the same temperature-regulating fluid passage or other temperature-regulating fluid passages in the second through section.

[0253] Alternatively, the one or more temperature-regulating fluid passages can be configured such that the second through-flow resistance of the temperature-regulating fluid from the first temperature-regulating zone to the second temperature-regulating zone in the second through-section is as large as the first through-flow resistance of the temperature-regulating fluid from the first temperature-regulating zone to the second temperature-regulating zone in the first through-section.

[0254] It is particularly advantageous to construct the one or more passages in such a way as to construct the one or more temperature-regulating fluid passages in such a way as to coordinate them with the one or more passages in such a way that uniform flow of the temperature-regulating fluid and / or the same flow rate of the temperature-regulating fluid and / or uniform temperature regulation of all energy storage elements that can be regulated by means of the temperature-regulating fluid can be achieved in the main flow direction in all regions of the temperature-regulating zone, for example in all regions of the first temperature-regulating zone.

[0255] For example, it can be envisioned that elements such as throttling devices / orifice plates are used in temperature-controlled fluid passages, which may include pipe sections or pipe segments with circular cross-sections, or that the cross-section of the temperature-controlled fluid passages is adjusted by machining, for example by drilling.

[0256] Advantageously, the temperature-regulating fluid barrier has two longitudinal sides, and correspondingly, one or more temperature-regulating fluid passages are arranged or constructed along the two longitudinal sides of the temperature-regulating fluid barrier on the inner side of the temperature-regulating fluid barrier.

[0257] It is particularly advantageous that the temperature-regulating fluid barrier has two longitudinal sides, and correspondingly multiple temperature-regulating fluid passages are arranged or constructed along the two longitudinal sides of the temperature-regulating fluid barrier on the inner side of the temperature-regulating fluid barrier.

[0258] The longitudinal side refers in particular to the following side of the temperature-regulating fluid barrier, which extends along a first direction, such as the length extension direction, and a third direction, such as the height extension direction, especially in a planar manner, wherein the longitudinal side of the temperature-regulating fluid barrier defines a temperature-regulating space on both sides, especially in a second direction, such as the width extension direction.

[0259] Preferably, the temperature regulating fluid barrier has two ends, and no temperature regulating fluid passage is arranged along the two ends of the temperature regulating fluid barrier, which connects the first temperature regulating zone and the second temperature regulating zone in a fluid guiding manner.

[0260] Advantageously, the temperature-regulating fluid passage extends in a third direction, such as the height extension direction, on the inner surface of the longitudinal side, for example, through the material constituting or forming at least the longitudinal side of the temperature-regulating fluid barrier, or through the material constituting or forming the separating element described herein, which surrounds the plurality of energy storage elements. The separating element may, for example, be a molded element described herein.

[0261] The separating element or forming element can be a carrier element, at which multiple energy storage elements of the energy storage unit are fixed.

[0262] One, multiple, or all temperature-controlled fluid passages can be manufactured by casting, for example by injection molding, from plastic materials.

[0263] Advantageously, the number of temperature-regulating fluid passages in the first through section is less than the number of temperature-regulating fluid passages in the second through section.

[0264] The temperature-regulating fluid passage according to the present invention can help achieve or benefit a more uniform distribution of the temperature-regulating fluid in the energy storage unit. This is particularly helpful in optimizing the cooling function.

[0278] Although the temperature-regulating fluid that can be guided in the temperature-regulating zone tends to flow in a lamellae pattern at a specific flow rate, more turbulence can occur at the same flow rate at the turbulence unit, which can achieve enhanced cooling of one or more energy storage elements due to the stronger mixing of the temperature-regulating fluid.

[0292] One of the contact areas of the storage element may exist, for example, on the surface of the conductive element.

[0293] Advantageously, the contact element segment extends at least along the connection region segment. The connection region segment may preferably be located between one or more of the energy storage elements and the contact element segment.

[0300] The contact element may be, for example, grid-shaped, thereby creating regularly spaced notches defined by the grid shape, and a reinforcing element extends through one of the notches formed by the grid shape. This notch then forms a reinforcing element notch.

[0301] For example, the corresponding reinforcing element notch may exist, especially or only, at the location where the reinforcing element is provided.

[0302] Advantageously, at least two, preferably at least four, particularly preferably at least six, for example at least eight, of the first reinforcing element and other reinforcing elements extend from the first barrier region to the second barrier region through one or more reinforcing element notches, preferably through multiple reinforcing element notches.

[0316] Advantageously, a shielding material can be placed at the monitoring unit or between the monitoring unit and the temperature-regulating space to prevent or reduce the flow of temperature-regulating fluid to the monitoring unit. This also helps to provide an efficient energy storage unit in the simplest possible way. In particular, it avoids cavitation in the structural space surrounding the monitoring unit. Simultaneously, it enables contact between the energy storage element and the energy storage element within the temperature-regulating fluid barrier, as a conductive connection can be established between the monitoring unit and the energy storage element within the temperature-regulating fluid barrier, thus eliminating the need for complex plug-sealed isolation components in the area of ​​the temperature-regulating fluid barrier.

[0427] Figures 1 to 6 A first embodiment of the energy storage unit 100 is shown. The energy storage unit 100 is an energy storage module 102. The energy storage unit 100 can provide electrical energy for driving a motorized vehicle (not shown).

[0428] Utilizing Figures 1 to 6 The energy storage unit shown can, for example, provide a portion of the electrical energy needed to power a mobile vehicle, wherein multiple energy storage units 100 shown can be interconnected to form an energy storage device (not shown). Other energy storage units 100 that can then be interconnected to form an energy storage device can provide the remaining electrical energy needed to power the mobile vehicle.

[0429] Energy storage unit 100 is an electrochemical energy storage unit 104. Energy storage module 102 is an electrochemical energy storage module 106.

[0430] The energy storage unit 100 includes a temperature-regulating fluid barrier 108. The temperature-regulating fluid barrier is a housing 110.

[0431] The temperature-regulating fluid barrier 108 has multiple barrier regions 112. The barrier regions 112 are wall regions 114.

[0432] Multiple barrier elements 115 together form a temperature-regulating fluid barrier. The first barrier element 116 is a cover element 118. The cover element 118 is a cap element 120.

[0433] exist Figures 1 to 6 In the illustrated embodiment, the first barrier element 116 includes a covering section 122 forming a channel barrier region 124. The first barrier element 116 forms a first barrier region 126. The first barrier region 126 is a first wall region 128.

[0434] The second barrier element 130 is also a cover element 118. This other cover element 118 is a bottom element 132. The second barrier element 130 forms the second barrier area 134.

[0435] The third barrier element 136 is a frame wall element 138. The third barrier element 136 forms the third barrier area 140. The third barrier element is a frame 142.

[0436] The third barrier element 136 has an inlet 150 and an outlet 148.

[0437] Temperature-regulating fluid can be introduced into the energy storage unit 100 through inlet 150.

[0438] Temperature-regulating fluid can flow out of the energy storage unit 100 through outlet 148.

[0439] The energy storage unit 100 extends in a first direction 152, a second direction 154, and a third direction 156. These three directions are oriented in a manner orthogonal to each other.

[0440] The first direction 152 can be understood as the length extension direction 158, along which the length of the energy storage unit 100 can be measured. The second direction 154 can be understood as the width extension direction 160 of the energy storage unit 100, along which the width of the energy storage unit 100 can be measured. The third direction 156 can be understood as the height extension direction 162, along which the height of the energy storage unit 100 can be measured.

[0441] Figure 2 The energy storage unit 100 is shown, which does not have the first barrier element 116.

[0442] from Figure 2 As can be seen, the energy storage unit 100 includes multiple energy storage elements 164. Energy storage elements 164 are electrochemical energy storage elements 166. These relate to battery cells 168, such as rechargeable lithium-ion battery cells.

[0443] A temperature-regulating fluid barrier 108 extends around the temperature-regulating space 170. In the temperature-regulating space 170, the energy storage element 164 can be temperature-regulated by means of the temperature-regulating fluid.

[0444] The energy storage unit includes multiple enhancement elements 172.

[0445] To improve clarity, Figure 2 In the figure, only a small portion of the energy storage element 164 and only a portion of the enhancement element 172 are marked with reference numerals.

[0446] exist Figures 1 to 6 In the first embodiment shown, the reinforcing element 172 is a sleeve 174. From Figure 2 , Figure 3 , Figure 5 and Figure 6 As can be clearly seen, the outer diameter of the reinforcing element 172 corresponds to the diameter of the energy storage element 164. The reinforcing element 172 has a notch 176.

[0447] The upper end 178 of the third barrier element 136 faces the... Figure 2The first barrier element 116 is not shown. A sealing element 180 or a weld 182 may be arranged between the upper wall end 178 and the first barrier element 116, for example. The weld 182 may preferably be a plastic weld, since the barrier elements, such as the first barrier element 116 and the third barrier element 136, may preferably be made of or constructed of plastic.

[0448] Figure 3 A cross-section of the energy storage unit 100, orthogonal to the length extension direction 158, along line III-III, is shown (see [reference]). Figure 1 ). Figure 3 It is shown, with regard to one of the reinforcing elements 172, how the reinforcing element 172 reinforces the barrier region 112 to prevent the barrier region 112 from bending outward, for example, to prevent the barrier region 112 from bulging outward. The direction in which the barrier region 112 would bend or bulge outward without the reinforcing element 172 is... Figure 3 The arrows pointing upwards and downwards are used to indicate the area of ​​the reinforcing element 172, which is drawn at the corresponding barrier area 112.

[0449] The reinforcing element 172 extends from the corresponding barrier region 112, namely from the first barrier region 126 and the second barrier region 184 already described, into the temperature control space 170.

[0450] If already combined Figure 1 As described, the first barrier zone 126 is the first wall zone 128. The second barrier zone 184 is the second wall zone 186.

[0451] The reinforcing element 172 extends from the first barrier region 126 to the second barrier region 184. The first barrier region 126 and the second barrier region 184 are mutually opposing barrier regions 112 of the temperature-regulating fluid barrier 108 formed by the first barrier element 116, the second barrier element 130 and the third barrier element 136.

[0452] Reinforcing element 172 includes a mating reinforcing element 188. The mating reinforcing element 188 is a supporting reinforcing element 190. In the example shown here, reinforcing element 172 is the mating reinforcing element 188.

[0453] The mating reinforcing element 188 reinforces the first barrier region 126 and the second barrier region 184 to correspondingly prevent the first barrier region 126 and the second barrier region 184 from bending inward, for example, concave. The inward bending of the first barrier region 126 and the second barrier region 184, and the concavity of the first barrier region 126 and the second barrier region 184, are addressed by... Figure 3 The black arrows pointing inwards into the temperature control space 170 indicate this.

[0454] exist Figure 4 In the middle, it is shown in a magnified manner. Figure 3The segment. The reinforcing element 172 has two ends 192. One of the ends 192 is a first end 194. The other of the two ends 192 is a second end 196. Barrier regions 112, 126 and 184 have recesses 198. The first barrier region 126 has a first recess 200. The second barrier region 184 has a second recess 202.

[0455] End 192 of the reinforcing element 172 is received in recess 198. First end 194 is received in first recess 200. Second end 196 is received in second recess 202. Figure 4 The reception of the second end portion 196 in the second recess 202 is shown. The reinforcing element 172 has a hollow cylindrical reinforcing wall 204. The second recess 202 is a second hollow cylindrical recess 206. The second end portion 196 of the reinforcing element 172 can be attached to the second recess 202, for example, by means of a material fit. Material fit attachment can be achieved, for example, by plastic welding or by means of an adhesive. This is in Figure 4 Not shown in the image.

[0456] Figure 3 It is also shown that the energy storage unit 100 includes a temperature-regulating fluid distribution channel 210 and a temperature-regulating fluid collection channel 208. The temperature-regulating fluid distribution channel 210 extends along a length extension direction 158 between the covered section 122 and the first temperature-regulating fluid guiding element 212.

[0457] The temperature-regulating fluid collection channel 208 extends against the length extension direction 158 between the other covered section 214 of the second barrier element 130 and the second temperature-regulating fluid guiding element 216.

[0458] Other covered sections 214 are other passageway barrier sections 218.

[0459] Especially from Figure 2 , Figure 5 and Figure 6 As can be clearly seen, the energy storage elements 164 are regularly arranged in the energy storage unit 100. In pairs of adjacent energy storage elements 164, the surfaces 220 of the energy storage elements are in contact with each other. Figure 6 This is particularly evident.

[0460] The positional states of the corresponding multiple energy storage elements define two parallel planes, between which the corresponding multiple of the energy storage elements 164 are arranged. From Figure 6 It is clearly seen that multiple energy storage elements 164 are correspondingly arranged between a first plane 222 and a second plane 224 extending parallel to the first plane, and similarly, multiple energy storage elements 164 are correspondingly arranged between a third plane 226 and a fourth plane 228 extending parallel to the third plane. These four planes are... Figure 6The line is shown as a straight line because the observer's line of sight extends along the surface of the plane.

[0461] The positional states of adjacent energy storage elements 164 can be approximated by a prism 230. Figure 6 The first prism 232 and the second prism 234 are shown. The edges extending along the sides of the two prisms 232 and 234 coincide with the straight lines extending through the energy storage element 164 in the center. Figure 5 It is clearly shown how the edge 238 extending along the side 242 of the prism 230 coincides with the straight line 240 that extends through the energy storage element 164 in the center.

[0462] In energy storage unit 100 Figures 1 to 6 In the first embodiment shown, the enhancement element 172 occupies the position of one of the energy storage elements 164 in the regular arrangement of the energy storage elements 164.

[0463] Energy storage unit 100 Figures 7 to 13 The second embodiment shown differs in particular, but not only, in this respect.

[0464] The difference comes from Figure 7 It is not clearly visible because the observer's view of the energy storage element is obscured at that point by the first barrier element 116. However, Figure 7 It is clearly shown that the channel barrier area 124 is not constructed in the covered section in the second embodiment shown here.

[0465] Figure 8 It shows Figure 7 The energy storage unit 100 does not have a first barrier element 116. It can be clearly seen that in the second embodiment shown here, the reinforcing element 172 does not occupy the position of the corresponding one of the energy storage elements 164 in the regular arrangement of the energy storage elements.

[0466] Instead, the reinforcing element 172 extends accordingly between the three energy storage elements 164 in the regular arrangement of the energy storage elements 164.

[0467] The other differences between the second embodiment and the first embodiment are that the number of reinforcing elements is substantially larger, and the diameter of the reinforcing element 172 is substantially smaller than that in the first embodiment.

[0468] Unlike the first embodiment, the end of the reinforcing element 172 is not received in the hollow cylindrical recesses of the barrier regions 112, 126, 184, but is received in the cylindrical recess 243. This is in Figure 10 It is shown in the figure, which shows Figure 9 The segment includes the second cylindrical recess 244.

[0469] Although in energy storage unit 100 Figures 1 to 6 In the first embodiment shown, the surfaces of adjacent pairs of energy storage elements touch correspondingly, but in the energy storage unit 100 Figures 7 to 13 In the second embodiment shown, a corresponding gap exists between the surfaces of adjacent energy storage elements 164. This is in Figure 13 This can be seen particularly well in the middle.

[0470] In energy storage unit 100 Figures 7 to 13 In the second embodiment shown, the spacing between two energy storage elements 164 in multiple pairs of adjacent energy storage elements 164 is the same. This is also evident from... Figure 11 As can be seen in the text.

[0471] Figure 12 A molded element 246 is shown. The molded element has a plurality of positioning regions 248. The positioning regions 248 are storage element receiving regions 250. In a second embodiment of the energy storage unit 100, energy storage elements 164 are arranged in the positioning regions 248. They are received in the storage element receiving regions 250. The spacing between the adjacent positioning regions 248 of the molded element 246 determines the spacing between adjacent energy storage elements 164.

[0472] The molding element 246 includes a plurality of temperature-controlled fluid guiding elements 252. Each temperature-controlled fluid guiding element 252 has a temperature-controlled fluid passage 254.

[0473] In a second embodiment of the energy storage unit 100, the molding element 246 defines a first temperature-regulating region 258 located on one side of the molding element and a second temperature-regulating region 256 located on the opposite side of the molding element 246. This is particularly true in... Figure 9 As can be seen, the temperature-regulating fluid can be transferred from the first temperature-regulating zone 258 to the second temperature-regulating zone 256 through the temperature-regulating fluid passage 254.

[0474] Figure 13 As shown, the reinforcing element 172 extends through the prism 230, which can be used to approximate the position of adjacent energy storage elements. The reinforcing element 172 extends through the prism 230, and in particular through the top and bottom surfaces of the prism.

[0475] Figures 14 to 16 A third embodiment of the energy storage unit 100 is shown. The energy storage unit 100 includes a temperature-regulating fluid barrier 108. The temperature-regulating fluid barrier 108 extends around a temperature-regulating space 170. The energy storage unit includes a plurality of energy storage elements 164. The energy storage elements 164 can be temperature-regulated in the temperature-regulating space 170 using a temperature-regulating fluid.

[0476] Energy storage unit 100 Figures 14 to 16The third embodiment shown includes a monitoring unit 260. The monitoring unit 260 is a monitoring circuit 262. The monitoring circuit 262 relates to a cell monitoring circuit 264. The cell monitoring circuit can, in particular, be a so-called battery cell monitoring circuit (CSC) 266.

[0477] The monitoring unit 260 can completely or partially avoid or compensate for differences in the state of charge of the energy storage element 164.

[0478] exist Figures 14 to 16 In the embodiment shown, the monitoring unit 260 is arranged in the monitoring area 268. The monitoring area 268 is located in the monitoring room 270.

[0479] The temperature-regulating fluid barrier 108 also forms the monitoring chamber barrier 272. Therefore, the temperature-regulating fluid barrier 108 also extends around the monitoring area 268 and around the monitoring unit 260 located therein.

[0480] exist Figure 14 and Figure 15 In the diagram, shielding material 274, which can prevent or reduce the flow of temperature-regulating fluid to the monitoring unit, is not shown.

[0481] Figure 16 The shielding material 274 is shown, with the energy storage unit 100 illustrated in a roughly simplified manner. The monitoring unit 260 is embedded in the shielding material 274. The shielding material includes a plastic material 276. The plastic material 276 is porous. It relates to a foam-like shielding material. For example, it could be a plastic foam material 278.

[0482] The plastic foam material 278 is fluid-tight. This ensures that the flow of temperature-regulating fluid to the monitoring unit 260 is prevented or reduced.

[0483] The average density of plastic foam material can be, for example, 0.08 g / cm³. 3 .

[0484] Energy storage unit 100 Figures 14 to 16 The third embodiment shown can be manufactured, for example, by having the monitoring unit 260 arranged in the monitoring chamber 270 and the monitoring chamber 270 filled with foam.

[0485] In this configuration, monitoring unit 260 can be introduced into monitoring chamber 270, and foam filling can be performed in a subsequent method step. Alternatively, monitoring chamber 270 can be completely or partially filled with foam. This can be achieved, for example, using a foaming agent. The arrangement of monitoring unit 260 in monitoring chamber 270 can be implemented in subsequent method steps, for example, in a foaming agent located within the monitoring chamber.

[0486] Figures 17 to 22 It shows Figures 14 to 16Other details of the energy storage unit 100.

[0487] Figure 17 As shown, the energy storage unit 100 has an inlet 150 and an outlet 148. Two associated openings 144 and 146 extend through a temperature-regulating fluid barrier 108. Temperature-regulating fluid can be supplied to the temperature-regulating space through the inlet 150. Temperature-regulating fluid can be discharged from the temperature-regulating space through the outlet.

[0488] Figure 17 As shown, the first span of the energy storage unit 100 in the first direction 152 is greater than the second span of the energy storage unit 100 in the second direction 154.

[0489] Figure 17 It is also shown that the first span of the energy storage unit 100 in the first direction 152 is greater than the third span of the energy storage unit 100 in the third direction 156.

[0490] Each of the three directions 152, 154, and 156 is oriented orthogonally to the other two directions. That is, the first direction 152 is oriented orthogonally to the second direction 154 and orthogonally to the third direction 156, the second direction 154 is oriented orthogonally to the first direction 152 and orthogonally to the third direction 156, and the third direction 156 is oriented orthogonally to the first direction 152 and orthogonally to the second direction 154.

[0491] The first direction 152 is the length extension direction 158. Therefore, the span of the energy storage unit 100 in the first direction 152 can be understood as the length of the energy storage unit 100.

[0492] The second direction 154 is the width extension direction 160. Therefore, the second span of the energy storage unit 100 in the second direction 154 can be understood as the width of the energy storage unit 100.

[0493] The third direction 156 is the height extension direction 162. Therefore, the span of the energy storage unit 100 in the third direction 156 can be understood as the height of the energy storage unit 100.

[0494] The temperature-regulating fluid barrier 108 has a plurality of barrier regions 112. These have been described in conjunction with other embodiments of the energy storage unit 100, and therefore will not be repeated here. One of the barrier regions 112 is an end-side barrier region 113. Thus, the temperature-regulating fluid barrier 108 has an end-side barrier region 113. An inlet 150 and an outlet 148 extend through the end-side barrier region 113. They extend through the end-side barrier region 113 such that the supply flow direction 280 of the temperature-regulating fluid supplied to the temperature-regulating space through the inlet 150 is oriented against the discharge flow direction 282 of the temperature-regulating fluid discharged from the temperature-regulating space through the outlet 148.

[0495] The end-side barrier region 113 is oriented such that it can be described by two end-side planes 284 and 286 that are parallel to each other and spaced apart from each other. The two end-side planes 284 and 286 are oriented orthogonally to the first direction 152. The end-side barrier region 113 extends between the two end-side planes 284 and 286.

[0496] exist Figure 17 Two end planes, 284 and 286, are drawn in the diagram.

[0497] Inlet 150 and outlet 148 are offset from each other on a third-party direction 156. Two associated openings 144 and 146 are offset from each other on a third-party direction 156 in the barrier area 113 on the end side.

[0498] Figure 17 As shown, the third embodiment of the energy storage unit 100 shown here also has an enhancement element 172.

[0499] Figure 18 The exploded view shows that the energy storage unit includes a temperature-controlled fluid collection channel 288, and an outlet 148 is connected to the temperature-controlled fluid collection channel 288 in a fluid-guided manner.

[0500] In the energy storage unit 100, the temperature-regulating fluid collection channel 288 is oriented such that a first section 292 of the temperature-regulating fluid collection channel 288, which is closer to the outlet 148 in the temperature-regulating fluid flow direction 290, and a second section 294 of the temperature-regulating fluid collection channel 288, which is farther from the outlet 148 in the temperature-regulating fluid flow direction 290, are offset to a smaller extent from the outlet 148 in a first direction 152. Simultaneously, the temperature-regulating fluid collection channel 288 is oriented such that the first section 292 of the temperature-regulating fluid collection channel 288, which is closer to the outlet 148 in the temperature-regulating fluid flow direction 290, and the second section 294 of the temperature-regulating fluid collection channel 288, which is farther from the outlet 148 in the temperature-regulating fluid flow direction 290, are offset to the same extent from the outlet 148 in a third direction 156.

[0501] The temperature-regulating fluid collection channel 288 has a fluid collection passage 296 through which the temperature-regulating fluid can be transferred from the temperature-regulating zone to the temperature-regulating fluid collection channel 288.

[0502] The fluid collection passage 296 widens with increasing distance from the second outlet 148. Therefore, the cross-section of the fluid collection passage 296 in the first section 292 of the temperature-controlled fluid collection channel 288 is smaller than the cross-section in the second section 294 of the temperature-controlled fluid collection channel 288. The width of the fluid collection passage 296 in the first section 292 of the temperature-controlled fluid collection channel 288, measurable transversely to the temperature-controlled fluid flow direction 290, is also smaller than the width in the second section 294 of the temperature-controlled fluid collection channel 288, measurable transversely to the temperature-controlled fluid flow direction 290. Accordingly, the width of the fluid collection passage 296 can be determined in the second direction 154.

[0503] exist Figure 19 The energy storage unit 100 is shown from above. The observer's line of sight extends in the opposite direction 156. Figure 19 It is also shown that the monitoring room 270 and the monitoring room barrier 272 surrounding the monitoring room are constructed in a manner opposite to the exit 148 and the entrance 150.

[0504] Figure 20 Corresponding to Figure 19 The text is incomplete and lacks context. Figure 19 The middle covers all the components and parts of the energy storage element 164. Figure 21 The barrier area 113 on the end side is shown in a magnified view. The observer's line of sight extends against the discharge flow direction 282 and along the supply flow direction 280.

[0505] Figure 22 It shows along Figure 19 The cross section of line XXII-XXII is drawn in the figure.

[0506] Figure 22 The cross-section shown illustrates the structure of the reinforcement element 172 installed in the energy storage unit 100 according to the third embodiment. The reinforcement element 172, shown in cross-section here, includes a mating reinforcement element 188. The mating reinforcement element 188 is a supporting reinforcement element 190. Figure 3 The working principle of the paired enhancement element 188 has been explained. Therefore, it will not be elaborated upon further.

[0507] The reinforcing element 172 includes two securing elements 298. The two securing elements 298 are screw connections 300. The securing elements allow the mating reinforcing element 188 to be secured at two barrier regions 112. One of the two barrier regions 112 is a first barrier region 126. The other of the two barrier regions 112 is a second barrier region 184. The reinforcing element 172 extends from the first barrier region 126 to the second barrier region 184. Figure 22The reinforcing element 172 shown has a shoulder region 302, a neck region 304, and a head region 306. It has a shoulder region 302, a neck region 304, and a head region 306 at each of its two ends. A securing region 308 is located in the neck region between the respective head region and the respective shoulder region. A first barrier region 126 extends into one of the two securing regions 308. A second barrier region 184 extends into the other of the two securing regions 308.

[0508] Two securing elements 298 form head regions 306 respectively. The two ends of the mating reinforcing element 188 form two shoulder regions 302.

[0509] The mating reinforcing element 188 and the two securing elements 298 have threads that engage with each other.

[0510] Figure 23 A segment of the cross-section of the energy storage unit 100 according to the present invention is shown. Figure 23 The energy storage unit 100 shown can be based on the references herein. Figures 1 to 22 The energy storage unit 100 described in the first, second, third or fourth embodiments.

[0511] In particular, the temperature control zone 255, such as the first temperature control zone 258, may also be as described herein with reference to the following embodiments. Figures 23 to 37 Designed as described.

[0512] Figure 23 An energy storage unit 100 is shown, which is an energy storage module 102. The energy storage unit 100 includes a plurality of energy storage elements 164 and a temperature-regulating fluid barrier 108.

[0513] Energy storage element 164 is an electrochemical energy storage element 166. It is a battery cell 168. In particular, it can be a rechargeable lithium-ion battery cell.

[0514] A temperature-regulating fluid barrier extends around the temperature-regulating space 170. The energy storage element 164 shown can be temperature-regulated within the temperature-regulating space 170 using the temperature-regulating fluid.

[0515] Figure 23 The temperature-regulating fluid barrier 108 shown has a barrier region 112. The barrier region is a wall region 114. The barrier region 112 is reinforced by means of a reinforcing element 172. Figure 23 The reinforcing element 172 shown is an external reinforcing element 330. It may in particular be a reinforcing rib extending from the outer surface of the barrier element 115 shown.

[0516] The reinforcing element 172 reinforces the barrier region 112 to prevent the barrier region 112 from bending outward. In particular, the reinforcing element 172 can reinforce the barrier region 112 to prevent the barrier region 112 from bulging outward. Figure 23 The external reinforcement element 330 shown does not extend from the barrier region 112 into the temperature control space 170.

[0517] Barrier area 112 includes barrier element 115. Barrier element 115 is a second barrier element 130. Second barrier element 130 is a cover element 118. Cover element 118 is a bottom element.

[0518] The temperature control space 170 has a temperature control zone 255. The temperature control zone is the first temperature control zone 258.

[0519] The energy storage unit 100 includes a turbulence-disrupting unit 312. The turbulence-disrupting unit 312 is arranged in the temperature regulation zone 255, that is, in the first temperature regulation zone 258.

[0520] The energy storage unit 100 includes, for each energy storage element 164, a plurality of conductive elements 318, 320 extending from the interior of the respective energy storage element 164 into a temperature regulation zone 255. These conductive elements can be temperature-regulated within the temperature regulation zone 255 using a temperature-regulating fluid. The conductive elements 318, 320 extending from the interior of one of the energy storage elements 164 together form a storage element contact region 316. The storage element contact region 316 serves as an electrode 356, wherein in the illustrated energy storage element 164, the electrode 356 is correspondingly a positive electrode 358.

[0521] The energy storage unit 100 includes a contact element 338. This can be the contact element 338 of the contact system 336, which is particularly referenced herein. Figures 33 to 37 To describe in more detail.

[0522] Due to contact element 338, there is a segment 341 of conductive connection 339 from at least one of the energy storage elements 164 of the energy storage cell 100 to the contact area of ​​the energy storage cell 100. This is in Figure 23 It is not visible in the middle.

[0523] Electrical energy, or a portion thereof, can be drawn from or supplied to the energy storage unit via the aforementioned contact area 350 and contact element 338.

[0524] Contact element 338 extends into temperature control zone 255.

[0525] Figure 23 As shown, the contact element 338 has a turbulence unit 312.

[0526] Furthermore, at least one section of the temperature regulation zone 255, namely the first temperature regulation zone 258, extends at the contact element 338 to the conductive elements 318, 320 of the energy storage elements on the right side of the two energy storage elements 164 shown, and extends around these conductive elements.

[0527] Contact element 338 serves as both fluid guiding unit 310 and temperature control zone dividing unit 314.

[0528] The turbulence unit 312 serves as a turbulence generator 326. The turbulence unit 312 has a passage area 324 that extends through the contact element 338.

[0529] Although the temperature-regulating fluid tends to flow in a laminar manner at a specific flow rate in the temperature-regulating zone 255, more turbulence can occur at the same flow rate at the turbulence unit 312. This can ensure enhanced cooling of the energy storage element 164 due to the stronger mixing of the temperature-regulating fluid. Figure 23 As shown on the right side of the image.

[0530] Figure 24 and Figure 25 A feasible design for the spoiler unit 312 is illustrated by way of example. Accordingly, only [the following is shown] Figure 23 Small segments, from which one can see and Figure 23 The deviation.

[0531] Figure 24 As shown, the contact element 338 has a bend 334 at the turbulence unit 312, such that the bend section 332 of the contact element can be used as a fluid deflection element 332. The fluid deflection element 332 particularly allows temperature-regulating fluid flowing on one side of the contact element 338 to impinge on the fluid deflection element 332 and escape through the passage region 324, thereby enhancing turbulence in the contact temperature-regulating region 322 and thus enabling stronger cooling of the energy storage element 164.

[0532] This can also be achieved through the turbulence unit 312. Figure 25 The design scheme shown can be implemented in a feasible way. Instead of... Figure 24 The curved portion 334 shown is in Figure 25 The feasible design shown contains three bends 334. Due to these bends 334, the contact element 338 is essentially bent into a U-shape in the cross-section shown.

[0533] exist Figures 26 to 32 The fifth embodiment of the energy storage unit 100 according to the present invention is shown in the figure.

[0534] According to the energy storage unit 100 of the present invention Figure 26 The fifth embodiment shown is similar in many respects to the energy storage unit 100 of the first to fourth embodiments. Therefore, it will not be described in detail in the accompanying drawings. Figure 26 The temperature-regulating fluid barrier 108 shown has a barrier region 112. The barrier region 112 shown here is also reinforced by means of a reinforcing element 172. A portion of the reinforcing element 172 may be... Figure 26As seen in the diagram, these reinforcing elements 172 are external reinforcing elements 330, which are arranged on the outside of the barrier area 112. The external reinforcing elements 330 are arranged in a grid pattern at the plurality of barrier areas 112, wherein, respectively, a portion of the external reinforcing elements 330 extends along the respective barrier area 112 in one direction and another portion of the external reinforcing elements 330 extends in another direction.

[0535] As can be clearly seen from the following attached figures, Figure 26 The energy storage unit 100 shown also has an enhancement element 172 extending from the barrier region 112 into the temperature regulation space.

[0536] exist Figure 27 It shows Figure 26 The energy storage unit 100 does not have a bottom element 132. Therefore, the components of the contact system 336 and monitoring system 340 included in the energy storage unit 100 are visible. Removing the bottom element 132 also allows free observation of the enhancement element 172.

[0537] exist Figure 28 In the middle, shown from below Figure 27 The energy storage unit 100 shown includes a monitoring system 340 and a contact system 336. It includes contact elements 338.

[0538] A segment 341 is established by one of the contact elements, forming a conductive connection 339 from the energy storage element 164 of the energy storage unit 100 to the contact area 350 of the energy storage unit 100. The energy storage element 164 and the contact area 350 are in... Figure 28 Invisible. The same applies to the second contact element 338, which is... Figure 28 As shown in the diagram. A segment 341 establishes additional conductive connections 339 from the energy storage element 164 of the energy storage unit 100 to other contact areas of the energy storage unit 100 via the second contact element 338. Other contact areas 350 are... Figure 28 It is also not visible in the middle.

[0539] from Figure 28 It can also be clearly seen that the two contact elements 338 each have a reinforcing element notch 370.

[0540] The reinforcing element 172 extends through the reinforcing element notch 370 into the temperature regulating space 170.

[0541] Figure 29 The view shown corresponds to Figure 28 The view is shown, in which the monitoring system 340 is not shown.

[0542] Figure 30 It shows Figure 26 The cross-section of the energy storage unit 100 along line XX. Figure 30 In the diagram, dashed arrows indicate the direction of flow of the corresponding temperature-regulating fluid.

[0543] Figure 30 Temperature-controlled fluid collection channel 208 and temperature-controlled fluid distribution channel 210 are also shown. These two channels 208 and 210 extend along the viewing direction. Inlet 150 is connected to temperature-controlled fluid distribution channel 210 in a fluid-guided manner. Outlet 148 is connected to temperature-controlled fluid collection channel 208 in a fluid-guided manner.

[0544] Figure 30 The energy storage element 164 of the energy storage unit 100 shown has a first end 366 and a second end 368. For clarity, only one of the energy storage elements 164 is provided with two reference numerals 366 and 368.

[0545] The energy storage element 164 has a first end 366 facing the first temperature regulation zone 258.

[0546] exist Figure 31 In the middle, a magnified view is shown Figure 30 The segment. Figure 31 As shown, the energy storage element 164 has two storage element contact areas 316. One of the storage element contact areas 316 is a positive electrode 358. The other of the storage element contact areas 316 is a negative electrode 360. The two storage element contact areas 316 are arranged at the first end 366 of the respective energy storage element 164.

[0547] Figure 31 As shown, the energy storage unit 100 includes a connection area 348 in which the storage element contact areas 316 of different energy storage elements 164 are electrically connected to each other.

[0548] In the connection area, the storage element contact areas of different energy storage elements are connected to each other via one of a plurality of connection devices 384.

[0549] Figure 32 Shown in 3D Figure 30 The cross-section. As can be clearly seen from the view shown here, at least one segment 341 of the corresponding conductive connection 339 from at least one of the energy storage elements 164 of the energy storage unit 100 to a corresponding contact area of ​​the two contact areas 350 of the energy storage unit 100 is established by two contact elements 338. Figure 32 The contact area shown on the left is the first contact area 352. Figure 32 The contact area shown on the right is the second contact area 354.

[0550] Terminals 342 may be present in the area of ​​contact region 350, wherein a first terminal 344 may be present in the area of ​​the first contact region 352 and a second terminal 346 may be present in the area of ​​the second contact region 354.

[0551] Figure 32 It is also shown that the two contact elements respectively have an indirect conductive connection 339 to one of the energy storage elements 164. The conductive connection 339 from the contact element 338 to the energy storage element 164 is established via the edge connection device 386.

[0552] Other segments 343 are established by the corresponding edge connection device 386, from the energy storage element 164 of the energy storage unit 100 to the corresponding conductive connection 339 of the corresponding contact area 350.

[0553] Figure 33 An example of a contact system 336 according to the present invention is shown. The contact system shown is installed in an energy storage unit 100 according to a fifth embodiment, which is in Figures 26 to 32 The contact system 336 shown is for contacting the energy storage element 164. Contact of the energy storage element 164 can be achieved on the connection side 390. The contact system is also adapted to guide temperature-regulating fluid in the temperature-regulating zones 255, 256, 258 of the energy storage unit 100, for example, the energy storage unit 100 according to one of the first to fifth embodiments described herein.

[0554] The contact system 336 includes a support element 372. The support element can be used, for example, to hold the energy storage element 164 in a desired position. The support element 372 can also be used to hold the coupling device 384, as described with reference to the following figures, in a desired position.

[0555] Figure 34 It shows Figure 33 The enlarged segment. Figure 34 As shown, the carrier element 372 has a positioning element 374. The positioning element 374 can be used to hold the energy storage element 164 at the connection side 390 in a desired position.

[0556] Figure 34 As shown, the contact system 336 has a connection region 376. The connection region 376 includes a positive connection region 378 and a negative connection region 380.

[0557] Figure 35 It was also shown Figure 33 and Figure 34 The contact system 336 shown in the figure does not have a carrier element 372. Figure 35As shown, the contact system 336 has a plurality of connecting devices 384 extending substantially parallel to each other. The connecting devices 384 also extend substantially parallel to the edge connecting devices 386 respectively located at two edges. The connecting devices 384 are connecting devices having at least two connecting regions 376, 378, and 380 that are electrically connected to each other. They each have at least two positive connecting regions 378 and negative connecting regions 380 that are electrically connected to each other.

[0558] Figure 36 It shows Figure 35 A cross-section of the view along line XXXVI-XXXVI. One of the connecting devices 384 forms a first connecting device. The connecting device 384 directly adjacent to it forms a second connecting device 394.

[0559] The negative electrode connection region 380 is located at the contact section 396 of the first connection device 392. The positive electrode connection region 378 is located at the contact section 396 of the second connection device 394.

[0560] These two contact sections 396 are adjacent to the contact temperature regulating area 322.

[0561] Contact element 338 has a turbulence-disrupting unit 312 at contact temperature regulation region 322. The turbulence-disrupting unit 312 serves as a turbulent element 326. In the example shown, it is implemented as a passage region 324. In contact temperature regulation region 322, a particularly efficient method for cooling energy storage element 164 can be achieved via storage element contact region 316 and conductive elements 318, 320 extending therein.

[0562] Figure 37 Corresponding to Figure 36 The connecting device 384 is not shown. From Figure 36 and Figure 37 It is clear that the insulating material 362 prevents direct electrical contact between the section of the contact element 338 extending along the connection region 348 and the connection region 348. The insulating material 362 forms a layer 364 disposed between the contact element 338 and the connecting device 384.

[0563] Figure 38 An energy storage unit 100 according to a fifth embodiment is also shown. (and) Figure 27 Unlike the view shown in the previous one, a temperature-regulating fluid guide element 211 is additionally shown. The temperature-regulating fluid guide element 211 is the first temperature-regulating fluid guide element 212.

[0564] In addition, the energy storage unit 100 includes other temperature-regulating fluid guiding elements 211. The other temperature-regulating fluid guiding element 211 is a second temperature-regulating fluid guiding element 216. The second temperature-regulating fluid guiding element 216 is arranged opposite to the first temperature-regulating fluid guiding element 212. Figure 39An energy storage unit 100 according to a fifth embodiment is shown, which does not have a cover element 120. The upper side of the second temperature-regulating fluid guiding element 216 is arranged below the cover element 120. The lower side of the first temperature-regulating fluid guiding element 212 is arranged above the bottom element 132.

[0565] from Figure 38 and Figure 39 As can be clearly seen, the energy storage unit 100 according to the fifth embodiment includes two temperature-regulating fluid guiding regions 414. One temperature-regulating fluid guiding region 414 is a temperature-regulating fluid distribution region 418. It is located in... Figure 38 As shown in the diagram. Another temperature-regulating fluid guiding region 414 is the temperature-regulating fluid collecting region 416. It is located in... Figure 39 As shown in the figure. The energy storage unit 100 according to the first to fourth embodiments further includes two temperature-regulating fluid guiding regions 414, one of which is a temperature-regulating fluid collection region 416, and the other of which is a temperature-regulating fluid distribution region 418.

[0566] The following is based on reference Figures 38 to 45 The fifth embodiment is described in illustrative detail.

[0567] Figure 38 and Figure 39 The two temperature-regulating fluid guide zones 414 shown extend through the temperature-regulating fluid guide channel 398, respectively.

[0568] Figure 38 As shown, the temperature-regulating fluid guiding region 414 includes a first guiding region segment 420 and a second guiding region segment 426. The first guiding region segment 420 shown here is a first distribution region segment 422. The second guiding region segment 426 shown here is a second distribution region segment 428.

[0569] Figure 39 The temperature-regulating fluid guiding region 414 shown also includes a first guiding region segment 420 and a second guiding region segment 426. The first guiding region segment 420 shown here is a first collecting region segment 424. The second guiding region segment 426 shown here is a second collecting region segment 430.

[0570] Figure 38 and Figure 39 The two first guide area segments 420 shown are opposite each other. Figure 38 and Figure 39 The two second guide sections 426 shown are also opposite each other.

[0571] Figure 38 The two guide sections 420 and 426 shown are as follows Figure 39The two guide zones 420 and 426 shown are indirectly arranged one after another in the direction of temperature control fluid flow 290, and the temperature control fluid can be guided in the corresponding temperature control fluid guide zone along the direction of temperature control fluid flow.

[0572] Figure 38 The guide sections 420 and 426 shown are as follows Figure 39 The guide sections 420 and 426 shown are offset from each other in a first direction 152, which is the length extension direction 158 of the energy storage unit 100.

[0573] Guide sections 420 and 426 are not demarcated in any way from the areas of temperature-regulating fluid guide section 414 that are adjacent to guide sections 420 and 426.

[0574] However, guide segments 420 and 426 were selected such that the first guide segment 420 in the first direction 152 has a first guide segment span 432 that is the same as the second guide segment 426 in the first direction 152 with a second guide segment span 434.

[0575] Figure 38 The temperature-controlled fluid distribution area 418 shown extends through the temperature-controlled fluid distribution channel 210.

[0576] Figure 39 The temperature-controlled fluid collection area 416 shown extends through the temperature-controlled fluid collection channel.

[0577] The temperature regulation space 170 of the energy storage unit 100 has two temperature regulation zones 255. Figure 38 The temperature control zone 255 shown is the first temperature control zone 258. Figure 39 The temperature control zone 255 shown is the second temperature control zone 256.

[0578] Figure 38 The temperature-regulating fluid guiding area 414 shown is connected to the first temperature-regulating area 258 via multiple passages 412 in a fluid guiding manner.

[0579] Figure 39 The temperature-regulating fluid guiding zone 414 shown is connected to the second temperature-regulating zone 256 via multiple passages 412 in a fluid-guiding manner. In both temperature-regulating fluid guiding zones 414, the passages are configured such that the second flow resistance of the temperature-regulating fluid transferring between the temperature-regulating zone 255 and the second guiding zone segment 426 is lower than the first flow resistance of the temperature-regulating fluid transferring between the temperature-regulating zone 255 and the first guiding zone segment 420.

[0580] There are various feasible ways to adjust the flow resistance of the pathway.

[0581] This is based on Figures 40 to 45The temperature-regulating fluid guiding element 211 shown can optionally be used as the first temperature-regulating fluid guiding element 212 (see [reference]). Figure 38 ) or used as a second temperature-regulating fluid guiding element 216 (see Figure 39 ).

[0582] Depending on whether it is used as a first temperature-regulating fluid guiding element 212 or as a second temperature-regulating fluid guiding element 216, the temperature-regulating fluid guiding region 414 can be used as a temperature-regulating fluid dispensing region 418 or a temperature-regulating fluid collecting region 416. The temperature-regulating fluid dispensing region 418 can extend through the temperature-regulating fluid dispensing channel 210. The temperature-regulating fluid collecting region 416 can extend through the temperature-regulating fluid collecting channel 208.

[0583] when Figure 40 When the temperature-regulating fluid guiding element 211 shown is used as a first temperature-regulating fluid guiding element, the first guiding region segment 420 is the first distribution region segment 422, and the second guiding region segment 426 is the second distribution region segment 428.

[0584] when Figure 40 When the temperature-regulating fluid guiding element 211 shown is used as the second temperature-regulating fluid guiding element 216, the first guiding region segment 420 is the first collecting region segment 424, and the second guiding region segment 426 is the second collecting region segment 430.

[0585] The first temperature-regulating fluid guiding channel section 400 may extend through the first guiding area section 420. The first temperature-regulating fluid dispensing channel section 402 may extend through the first dispensing area section 422. The first temperature-regulating fluid collecting channel section 404 may extend through the first collecting area section 424.

[0586] The first temperature-regulating fluid distribution channel section 402 may, for example, be the first section 292, which is also described herein in conjunction with other accompanying drawings. The first temperature-regulating fluid collection channel section 404 may, for example, be the first section 292, which is also described herein in conjunction with other accompanying drawings.

[0587] The second temperature-regulating fluid distribution channel section 408 may, for example, be the second section 294, which is also described herein in conjunction with other accompanying drawings. The second temperature-regulating fluid collection channel section 410 may, for example, be the second section 294, which is also described herein in conjunction with other accompanying drawings.

[0588] exist Figure 40 In the first guide zone segment 420, the first guide zone segment span 432 in the first direction 152 is the same as the second guide zone segment 426 in the first direction 152 span 434.

[0589] In Figure 40When the temperature-regulating fluid guiding element 211 shown is used in the energy storage unit 100 according to the present invention, the temperature-regulating fluid guiding region 414 can be connected to one of the two temperature-regulating regions 255, 256, 258 in a fluid guiding manner via a plurality of passages 412.

[0590] from Figure 40 As can be directly seen, passage 412 is configured such that the second flow resistance of the temperature-regulating fluid transferring between temperature-regulating zones 255, 256, 258 and the second guide zone segment 426 is lower than the first flow resistance of the temperature-regulating fluid transferring between temperature-regulating zones 255, 256, 258 and the first guide zone segment 420.

[0591] Therefore, the first cross section 436 of the passage 412 in the first guide area segment 420 is smaller than the second cross section 438 of the other passage 412 in the second guide area segment 426.

[0592] Figure 41 Other temperature-regulating fluid guiding elements 211 are shown. The size 440 of the passage 412 in the first guiding section 420 is smaller than the size 440 of another passage in the second guiding section 426. Figure 41 In this context, dimension 440 corresponds to diameter 446. Diameter 446 corresponds to minimum diameter 442.

[0593] Figure 42 The temperature-regulating fluid guiding element 211 shown is similar to Figure 41 The temperature-regulating fluid guiding element 211 is shown. In... Figure 42 In the illustrated temperature-regulating fluid guiding element 211, the temperature-regulating fluid guiding region 414 has a tapering region 450. The temperature-regulating fluid guiding region 414 tapers in the temperature-regulating fluid flow direction 290 within the tapering region 450, allowing the temperature-regulating fluid to be guided within it along the flow direction. Alternatively, the temperature-regulating fluid guiding region may taper in the tapering region 450 against the flow direction 290. This depends on whether the temperature-regulating fluid guiding element 211 is used as a second temperature-regulating fluid guiding element 216 for collecting the temperature-regulating fluid or as a first temperature-regulating fluid guiding element for dispensing the temperature-regulating fluid.

[0594] Figure 43 Shown in 3D Figure 42 Temperature-regulating fluid guiding element 211.

[0595] Figure 43 As shown, the temperature-regulating fluid guide region 414 tapers in the tapering region 450 along a second direction 154, which may be, for example, the width extension direction 160 of the energy storage unit 100.

[0596] Figure 44 Shown in 3D Figure 41Temperature-regulating fluid guiding element 211.

[0597] exist Figure 41 and Figure 44 The temperature-regulating fluid guiding element 211 shown and in Figure 42 and Figure 43 In the temperature-regulating fluid guiding element 211 shown, the number of passages 412 in the first guiding region segment 420 is less than the number of passages 412 in the second guiding region segment 426. This is in Figure 41 China exemplarily targets Figure 41 and Figure 44 The temperature-regulating fluid guiding element 211 is shown.

[0598] Figure 45 The illustrated temperature-regulating fluid guiding element 211 also has a passage 412 through which the temperature-regulating fluid guiding region 414 can be fluid-guidedly connected to the temperature-regulating regions 255, 256, and 258. This passage is configured such that a second flow resistance to the transfer of the temperature-regulating fluid between the temperature-regulating regions 255, 256, and 258 and the second guiding region segment 426 is lower than a first flow resistance to the transfer of the temperature-regulating fluid between the temperature-regulating regions 255, 256, and 258 and the first guiding region segment 420.

[0599] The size 440 of the passage 412 in the first guide area segment 420 is smaller than the size 440 of the same passage 412 in the second guide area segment 426. This size could be, for example, [missing information - likely a size value]. Figure 45 The width of the slot-shaped passage 412 shown.

[0600] In addition, Figure 45 In the temperature-regulating fluid guiding element 211 shown, the first cross-section 436 of the passage 412 in the first guiding region segment 420 is smaller than the second cross-section 438 of the same passage in the second guiding region segment 426. The cross-section here can in particular be the cross-sectional area of ​​the segment of passage 412 located in the respective guiding region segment 420 or 426.

[0601] exist Figure 38 and Figure 39 In the diagram, the shortest temperature control path 452 is plotted as dots. The shortest temperature control path 452 starts from... Figure 38 The illustrated pathway 412 is via the same... Figure 38 The first temperature-regulating zone 258 shown in the figure is connected to the temperature-regulating fluid passage 254. Figure 39 The second temperature control zone 256 can be seen in the image. The shortest temperature control path 452 further leads to the second temperature control zone 256. Figure 39 The path shown is 412.

[0602] Additionally, in Figure 39The maximum spacing between the passage ends 454 is shown. This maximum spacing is also shown in a dotted manner. Dotted lines connect the two passage ends 454.

[0603] from Figure 38 and Figure 39 As can be seen, the length of the shortest temperature control path 452 is at most 150% of the maximum spacing between the ends 454 of the passage that can be measured in the first direction 152.

[0604] In all embodiments shown in the figure, the temperature-regulating space 170 has a first temperature-regulating zone and a second temperature-regulating zone. Furthermore, the energy storage unit 100 has a plurality of temperature-regulating fluid passages 254. The temperature-regulating fluid passages 254 connect the first temperature-regulating zone 258 and the second temperature-regulating zone 256 in a fluid-guiding manner. Figure 9 A first temperature-regulating region 258 and a second temperature-regulating region 256 are shown as an example for one embodiment. In the embodiment shown here, the temperature-regulating fluid passage 254 is integrated into... Figure 12 In the molded element 246 shown.

[0605] The present invention does not preclude the existence of one or more other temperature-regulating zones between the first temperature-regulating zone 258 and the second temperature-regulating zone 256. That is, the temperature-regulating fluid passage 254 does not necessarily have to lead directly from the first temperature-regulating zone 258 to the second temperature-regulating zone 256.

[0606] It is conceivable that the first temperature-regulating zone 258 is indirectly connected to the second temperature-regulating zone 256 via one or more temperature-regulating fluid passages 254 and at least one other temperature-regulating zone. For example, other temperature-regulating fluid passages may be provided between one of the other temperature-regulating zones and the second temperature-regulating zone 256.

[0607] Figure 39 Other embodiments are shown, wherein a plurality of temperature-regulating fluid passages 254 include a first through section 456 and a second through section 458, wherein the through section span 460 of the first through section 456 in a first direction 152 is the same as the second through section span 462 of the second through section 458 in the first direction 152, the first direction being the length extension direction 158 of the energy storage unit 100.

[0608] The two through sections 456 and 458 are staggered in the first direction 152.

[0609] It is possible that the temperature-regulating fluid passage 254 is configured such that the second through flow resistance of the temperature-regulating fluid in the second through section 458 from the first temperature-regulating zone 258 to the second temperature-regulating zone 256 is lower than the first through flow resistance of the temperature-regulating fluid in the first through section 456 from the first temperature-regulating zone 258 to the second temperature-regulating zone 256.

[0610] In observation Figure 39 It is clear that the second temperature-regulating fluid guide path 465, centrally located at the inlet 150, passing through the second through section 458 to the outlet 148, is longer than the first temperature-regulating fluid guide path 464, centrally located at the inlet 150, passing through the first through section to the outlet. Figure 39 The image shows the arrows that indicate the direction of the first temperature-regulating fluid guide path 464, which guides the fluid through the first through section 456, in the second temperature-regulating zone 256.

[0611] Advantageously, the size 440 of the temperature-regulating fluid passage 254 in the first through section 456 may be smaller than the size 440 of the same temperature-regulating fluid passage 254 or another temperature-regulating fluid passage 254 in the second through section 458. The size may be, in particular, a diameter 446, such as a minimum diameter 442.

[0612] It can be envisioned that the first cross section 436 of the temperature-regulating fluid passage 254 in the first through section 456 is smaller than the second cross section 438 of the same temperature-regulating fluid passage 254 or another temperature-regulating fluid passage 254 in the second through section 458.

[0613] It can also be envisioned that the number of temperature-regulating fluid passages 254 in the first through section 456 is less than the number of temperature-regulating fluid passages 254 in the second through section 458.

[0614] In all the embodiments shown in the figures, Figure 38 On the exemplarily indicated main flow direction 466, starting from the temperature-regulating fluid distribution area 418, up to 20 energy storage elements 164, for example, up to 12 energy storage elements 164, can be temperature-regulated by means of a temperature-regulating fluid that can be guided in the main flow direction 466. Figure 38 As shown, the main flow direction 466 extends parallel to the second direction 154, which is the width extension direction 160 of the energy storage unit 100. The main flow direction 466 extends toward the temperature regulating fluid passage 254 in this direction.

[0615] Figure 39 The reverse flow direction 468 is shown. The reverse flow direction 468 extends against the main flow direction 466 through the second temperature-regulating zone 256 toward the temperature-regulating fluid collection zone 416. On the reverse flow direction 468, starting from the temperature-regulating fluid passage 254, up to 20 energy storage elements 164, for example, up to 12 energy storage elements 164, can be temperature-regulated by means of the temperature-regulating fluid that can be guided on the reverse flow direction 468.

[0616] For example, especially from Figure 30As can be clearly seen, in the first temperature-regulating zone 258, in the main flow direction 466, the first ends 366 of up to 20 energy storage elements 164, for example, up to 12 energy storage elements 164, can be temperature-regulated by a temperature-regulating fluid that can be guided in the main flow direction 466. Furthermore, in the second temperature-regulating zone 256, in the reverse main flow direction 468, the second ends 368 of up to 20 energy storage elements 164, for example, up to 12 energy storage elements 164, can be temperature-regulated by a temperature-regulating fluid that can be guided in the reverse main flow direction 468.

[0617] The first end 366 and the second end 368 are the opposite ends 366 and 368 of the same energy storage element in up to 20 energy storage elements 164, for example, up to 12 of the same energy storage elements 164.

[0618] In the method for controlling the temperature of the energy storage element 164 according to the present invention, a temperature-regulating fluid is supplied to a first central region 470 of a first temperature-regulating region 258 of the energy storage unit 100. The first central region 470 extends through the first temperature-regulating region 258 in the longitudinal direction 471. The first central region divides the first temperature-regulating region 258 into an outflow region 472 located on one side of the first central region 470 and a second outflow region 474 located on the other side of the first central region 470. Figure 38 This is illustrated by way of example in the embodiment of the energy storage unit 100 shown here.

[0619] The temperature-regulating fluid supplied to the first temperature-regulating zone 258 is divided into the first outflow zone 472 and the second outflow zone 474, and is guided therein in a manner that it comes into heat exchange contact with a portion of the energy storage element 164 of the energy storage unit 100.

[0620] In the method according to the invention, it may be specified that a temperature-regulating fluid, which is guided and heated in a manner corresponding to heat exchange contact with a portion of the energy storage element 164, is discharged from the energy storage unit 100 in a method step located indirectly or directly upstream.

[0621] Figure 38 It is also shown that at least a portion of the temperature-regulating fluid supplied to the first temperature-regulating zone 258 diffuses in the first outflow zone 472 and in the second outflow zone 474 along opposite main flow directions 466.

[0622] The number of energy storage elements 164 arranged sequentially from the first central region 470 along the main flow direction 466 is so small, and so much temperature-regulating fluid is transported through the energy storage unit 100, that is, during the charging process of the energy storage unit 100, that is, when the energy storage unit 100 increases from a 10% charge state to a 90% charge state within 30 minutes, the temperature of the temperature-regulating fluid flowing out of the energy storage unit is no more than 6K, preferably no more than 4K, and for example no more than 2.5K, relative to the temperature of the temperature-regulating fluid flowing into the energy storage unit.
