Description

[0001] This application is a divisional application of Chinese Patent Application No. PCT / US2021 / 045242, filed on August 9, 2021, with International Application No. PCT / US2021 / 045242, National Application No. 202180030613.8, entitled "Casing for Electricity Storage Device, Electricity Storage Device Including the Casing and Vehicle Including the Electricity Storage Device".

[0002] Cross-reference to related applications This application claims the benefit of U.S. Provisional Patent Application No. 63 / 063,795, filed August 10, 2010, entitled "House for Electric Power Storage Device, Electric Power Storage Device Including the House, and Vehicle Including the Electric Power Storage Device," and U.S. Provisional Patent Application No. 63 / 191,673, filed May 21, 2021, entitled "Battery Connector and Battery Cover," the entire contents of which are incorporated herein by reference for all purposes. Technical Field

[0003] This disclosure relates to an energy storage device, such as a lead-acid battery having a downward holding assembly. The downward holding assembly is typically mounted on the battery casing, allowing the battery to be attached to a vehicle using a clamp, for example. Background Technology

[0004] Referring to Figures 1 and 2, an internal combustion engine 10 of a vehicle is shown. A lead-acid battery 15 according to a prior art structure is also shown. The battery 15 is configured to provide at least partial power to start or operate the vehicle and / or various vehicle systems. The vehicle can be one of many types of vehicles, including automobiles, motorcycles, buses, recreational vehicles, boats, etc. The battery 15 includes a housing 20, which may be at least partially made of a plastic resin and has a box-shaped container (or compartment) 25.

[0005] For the structure shown in Figures 1 and 2, compartment 25 includes skirts (skirts 30 and 35, as shown in Figure 2) at the bottom of the front, rear, and side walls (walls 40 and 45, as shown in Figure 2). A clamp (clamp 50, as shown in Figure 1) is coupled to the skirts and secures the battery 15 in place. Positioning the downward retaining assembly at the bottom of the battery does not provide the most secure connection between the battery and the vehicle. For example, because the top of the battery is farther from the retaining assembly, vibrations during vehicle operation may have a greater impact on the top of the battery. An alternative mounting arrangement for the downward retaining assembly, as shown in Figures 1 and 2, offers better stability.

[0006] In addition, lead-acid batteries typically have positive and negative terminals. Example terminals can be essentially cylindrical posts extending above the top surface of the battery cover, or protruding from the side of the battery container. In many applications, terminals are connected to equipment or machinery (such as vehicles) using clip-on connectors. In some applications, the clip-on connector may rotate and / or slide on the terminals, thus failing to provide a secure or stable connection. Furthermore, any movement of the connector relative to the terminals can cause wear on the terminals and / or clamps, which can ultimately affect the performance of the connection between the battery and the connector. Summary of the Invention

[0007] This disclosure presents a downward retaining assembly for a battery. The downward retaining assembly, in at least one embodiment, includes a skirt located in the middle of the battery housing. Positioning the skirt in the middle of the battery housing limits the amount by which the housing protrudes above the battery mounting platform. Furthermore, the skirt positioned in the middle of the housing provides a more stable solution than prior art batteries.

[0008] In at least one embodiment, a housing for a power storage device is disclosed. The housing includes a compartment having a bottom, a first wall extending from the bottom, and a second wall extending from the bottom. The housing further includes a first skirt portion and a second skirt portion for downwardly holding the housing as part of a downwardly retaining assembly. The first skirt portion and the second skirt portion are respectively disposed on the first wall and the second wall, and are positioned between 15% and 85% of the height of the first wall and the second wall between their bottom and top.

[0009] In at least another embodiment, a power storage device including the housing is disclosed. In at least another embodiment, a vehicle is disclosed. The vehicle includes a mounting surface, a power storage device, and a downward retaining assembly including a downward retaining structure engaging with a first skirt portion and a second skirt portion.

[0010] This disclosure presents an example battery terminal. The example terminal includes one or more features that provide a more robust connection between the vehicle connector and the terminal than a conventional clip-on connector. In other words, the example terminal reduces or eliminates movement of the connector relative to the terminal, thereby reducing wear and improving connection performance.

[0011] In some examples, the terminal is a female terminal. In such examples, the terminal may include an annular ring or groove. In other such examples, the terminal may include a threaded portion. In other examples, the terminal includes one or more protrusions. Furthermore, the portion of the cover adjacent to the terminal has a keyed portion to secure the connector.

[0012] These and further advantages are known from this disclosure. Attached Figure Description

[0029] It should be understood that the accompanying drawings are not necessarily drawn to scale. In some cases, details that are not necessary for understanding the invention or other details that are not easily noticeable have been omitted. Of course, it should be understood that the invention is not limited to the apparatus or process shown herein. Detailed Implementation

[0030] One or more specific embodiments will now be described. To provide a concise description of these embodiments, not all features of actual embodiments are described in this specification. It should be recognized that in the development of any such actual embodiment, such as in any engineering or design project, numerous decisions must be made specifically for the implementation to achieve the developer's specific goals, such as complying with system-related and business-related constraints, which may vary from implementation to implementation. Furthermore, it should be recognized that such development work can be complex and time-consuming, but would be routine design, manufacturing, and production work for those skilled in the art who benefit from this disclosure.

[0031] Referring to the accompanying drawings, a power storage device 100 is disclosed, particularly a rechargeable battery, such as a lead-acid battery and a lithium-ion battery. According to one or more examples of embodiments, the power storage device 100 is a lead-acid battery. Various embodiments of lead-acid batteries can be sealed (e.g., maintenance-free) or unsealed (e.g., wet-cell). According to one or more embodiments, the lead-acid battery 100 is preferably a sealed lead-acid battery or an AGM lead-acid battery for this purpose. Although specific examples have been described and illustrated, the battery 100 can be any secondary battery suitable for the given purpose. Figure 3 The battery 100 is provided and shown in the vehicle 102.

[0032] Reference Figure 4 An electric power storage device 100 (such as a lead-acid battery) is shown. The electric power storage device 100 can be used in one of a variety of types of vehicles, including automobiles, motorcycles, buses, recreational vehicles, boats, etc. The electric power storage device 100 is configured to provide at least a portion of the power for starting or operating the vehicle and / or various vehicle systems. Furthermore, it should be understood that the electric power storage device 100 can be used in various applications not involving vehicles, and such applications are all within the scope of this disclosure.

[0033] A housing (or enclosure) 105 for an electric power storage device 100 is disclosed. The housing 105 includes a box-shaped container (or compartment) 110 and is at least partially made of a plastic resin. Various structures include, for example... Figures 5 to 8 The structure shown indicates that container 110 has multiple walls 115A-E. These walls 115A-E may be referred to as first to fifth walls 115A-E, respectively.

[0034] In various structures, including such Figures 5 to 8 The structure shown indicates that the interior of container 110 includes six unit compartments 120A-F, which are separated by five internal partitions 125A-E between walls 115A and 115C. In some other embodiments, the number of partitions 125 and compartments 120 can be varied to obtain power storage devices with different voltages.

[0035] Reference Figures 4 to 8A cover (or shroud) is provided for a housing 105 and coupled to a container 110. The cover 130 includes a wall 135 and projecting edges integrally formed with the wall 135 (edges 140A and 140B as shown). In the structure shown, the projecting edges surround the lips 145A-D of the walls 115A-D. The cover 130 includes terminals 150A and 150B and filling tubes 155A and 155B. The filling tubes 155A and 155B allow electrolyte to be added to the battery and allow for maintenance. To prevent electrolyte from overflowing from the filling tubes 155A and 155B and to allow gases generated during the electrochemical reaction to escape, the housing 105 may also include one or more filling caps 160A and 160B and vents 165A-D.

[0036] Positive terminals 150A and negative terminals 150B can be found on one or more walls 115A-E and / or cover 130 of the power storage device 100. The positive and negative terminals 150A and 150B typically include portions extending through the cover 130 and / or wall, depending on the design of the power storage device. Therefore, various terminal arrangements and designs are possible.

[0037] For the structure shown in the figure, walls 115A-D can be referred to as side walls 115A-D. Wall 115E can be referred to as bottom wall 115E, and wall 135 can be referred to as top wall (or cover wall) 135. The bottom wall (or simply bottom wall) of the container 110 can be mounted on the mounting surface (or tray) 170 (e.g., Figure 3 Above or inside (as clearly shown). Figure 3 The mounting surface 170 is exaggerated and includes a through hole 172. The downward retaining assembly 175 is similar to the downward retaining assembly 175 shown in FIG1. ​​The downward retaining assembly 175 can be used to secure the power storage device 100 in place. Referring to FIG1 and... Figure 3 The downward retaining assembly 175 includes a clamp 50 having a clamping rod 185, a bolt 190, a through hole 192, and a retaining mechanism (such as a washer and a lock nut). Furthermore, Figures 9 to 12 An example of a power storage device with a clamp 50 is described, which can be used with the example downward holding assembly 175. In some examples, the clamp 50 is a C-bracket type clamp, including a C-clamp strip 185 and a mounting piece 187 with a through hole 192. The through hole 192A in the mounting piece 187 is aligned with a through hole 192B in a metal frame 194. Bolts 190 are positioned through the through holes 192A in the mounting piece 187 and the metal frame 194 to secure the power storage device 100. The metal frame 194 may be integrated into or attached to the mounting surface 170. In some such examples, for example in Figure 9 and Figure 10In the example structure shown, the two sides of the C-shaped clamp strip 185 extend toward and contact the metal frame 194, such that the mounting piece 187 of the clamp 50 directly contacts the metal frame 194. Alternatively, as... Figure 11 and Figure 12 In the example structure shown, the C-shaped clamp strip 185 extends only partially onto the metal frame 194 on both sides, leaving a gap between the mounting piece 187 and the metal frame 194. In some examples, the bolts are designed to extend between the mounting piece and the metal frame. A downward retaining assembly 175 is also included as a skirt (discussed below). The design of the downward retaining assembly can vary depending on the prior art.

[0038] Refer again Figures 4 to 8 The skirt panels 195A-D are integrally formed with the container 110. In the prior art, the skirt panels 195A-D include several battery clip mounting structures (mounting structure 200 is shown). Figures 4 to 8 The illustrated skirt panel (e.g., skirt panel 195A) includes a canopy portion (e.g., 205A) and a support portion (e.g., support portion 210). The support portion 210, as shown, is fin-shaped to aid in supporting the canopy portion 205. The canopy portion 205 includes the battery clip mounting structure. It is conceivable that other skirt panels and skirt panel designs known in the prior art could be used instead of the illustrated skirt panel, including the illustrated canopy and fins.

[0039] The sidewalls 115A-D of the container 100 have a height H defined from the bottom wall 115E to the top of the sidewalls 115A-D. Preferably, a skirt 195 is formed or fixed to the sidewalls 115A-D at a position between 15% and 85% of the height H of the sidewalls 115A-D from the bottom wall 115E to the top of the sidewalls 115A-D. Therefore, the skirt 195 between 15% and 85% of the height H of the sidewalls 115A-D limits the number of housings 105 protruding above the mounting surface 170 for the power storage device 100. Furthermore, positioning the skirt between 15% and 85% of the height H of the sidewalls 115A-D provides a more stable solution than prior art batteries. In a preferred embodiment, the skirt panel 195 is formed or fixed to the side wall 115A-D at a position between 15% and 75% of the height H of the side wall 115A-D from the bottom wall 115E to the top of the side wall 115A-D. In a more preferred embodiment, the skirt panel 195 is formed or fixed to the side wall 115A-D at a position between 30% and 65% of the height H of the side wall 115A-D from the bottom wall 115E to the top of the side wall 115A-D. In a more preferred embodiment, the skirt panel 195 is formed or fixed to the side wall 115A-D at a position between 40% and 60% of the height H of the side wall 115A-D from the bottom wall 115E to the top of the side wall 115A-D.

[0040] like Figure 4 The example structure of the illustrated power storage device also describes example terminals 150A and 150B. As shown in the example, terminals 150A and 150B are located on a portion 215 of the battery cover 130, which is recessed relative to the top surface 220 of the battery cover 130 (e.g., on a different plane). Alternatively, terminals 150A and 150B may be located on one side of the battery housing or casing. The example terminals 150A and 150B can be shaped such that only a specific battery or battery type can be used with a specific connector. The recessed portion 215 may also have a shape corresponding to a specific connector or connector type. In some example structures, such as Figures 13 to 21 The examples depicted herein, with example terminals 150A and 150B, are female connectors (e.g., receiver connectors, receptacles, notches, slots, etc.) that allow threaded or keyed connections, are more secure than typical clamps on cylindrical terminals extending above the battery surface. For example, the construction of example terminals 150A and 150B described herein can reduce or prevent rotation of the connectors coupled to said terminals 150A and 150B, which reduces wear on said terminals 150A and 150B and also provides a more secure connection to said terminals 150A and 150B.

[0041] Figures 13 to 15An example structure of a power storage device 100 with example female terminals 150A and 150B is depicted. The example power storage device shown can be a lead-acid battery including a positive terminal 150A and a negative terminal 150B. The example power storage device 100 can be used with a vehicle 102 or for other applications. Alternatively, the power storage device 100 with female terminals 150A and 150B may be a different type of chemical battery (e.g., a lithium-ion battery) having positive and negative terminals and a similar cap or container.

[0042] Figure 16 and Figure 17 Drawn in Figure 4 A more detailed view of the example terminals 150A and 150B shown. Figures 13-15 Drawn Figure 17 Cross-sectional views of example terminals 150A and 150B as described in the figure. Figure 16 and Figure 17 The example terminals 150A and 150B shown are female connections. The example terminals 150A and 150B can be made of conductive, lead-free materials, such as aluminum, copper, steel, brass, etc. Using lead-free materials results in a battery 100 with no exposed lead. Since the end consumer does not come into contact with lead, the lead-free battery 100 can offer many benefits (e.g., environmental benefits, health benefits).

[0043] like Figure 16 and Figure 17 The structure shown includes terminals 150A and 150B, each including a protrusion 225 that partially extends around the inner wall 230 of the terminals 150A and 150B. For example, as... Figure 16 and Figure 17 The terminals 150A and 150B shown include three evenly spaced protrusions 225, each protrusion 225 spanning approximately 60 degrees (e.g., one-sixth of a circle) around the inner circumference of the terminals 150A and 150B. The example protrusion 225 has square edges, but can be replaced with protrusions of any suitable shape, size, or number. In the illustrated example, the protrusions 225 are positioned closer to the top of the terminals 150A and 150B than their bottom surfaces, but still maintain a distance from the top edge of the terminals. Alternatively, the protrusions 225 may be located in the middle of the terminal wall or closer to the bottom surface.

[0044] like Figure 16 and Figure 17 The example terminals shown also include a sleeve 230 and a conductive bridge 235. However, as Figure 16 and Figure 17The terminals 150A and 150B shown do not include the surrounding portion, so the sleeve 230 and the conductive bridge 235 are made of the same material as the terminals 150A and 150B. The terminals 150A and 150B can be leaded or lead-free metals (e.g., aluminum, steel, copper, brass, etc.).

[0045] As mentioned above, such as Figure 16 and Figure 17 The described structure of terminals 150A and 150B makes the connection between terminals 150A and 150B and the connector more secure. Furthermore, as... Figure 16 and Figure 17 The top edges of the example terminals 150A and 150B protrude relative to the recessed portion 215 of the cover 130. In the example shown, the cover 130 does not enclose the top edges 240 of the terminals 150A and 150B, but in other examples, the cover 130 may enclose the top edges 240 of the terminals 150A and 150B. The edge of the recessed portion 215 has a key 245 for securely connecting the connector. As shown in the example, the keyed portion 245 includes one or more slots 250 at the edge of the recessed portion 215. Specifically, the slot 250 includes a vertical portion 255 and a horizontal portion 260, which allows the connector to be downwardly connected to the terminals 150A and 150B and then rotated to lock in place. Furthermore, the bottom of the peripheral portion of the terminals 150A and 150B may include a toothed portion 265 to prevent rotation or twisting of the terminals 150A and 150B.

[0046] Figure 18 More detailed views of example terminals 150A and 150B are depicted, such as... Figures 13 to 15 One example is terminals 150A and 150B. Figure 19 Depicting Figure 18 Cross-sectional views of example terminals 150A and 150B. Figure 18 and Figure 19 Example terminals 150A and 150B are female connectors. The example terminals 150A and 150B can be made of conductive lead-free materials, such as aluminum, copper, steel, brass, etc. Using lead-free materials results in batteries with no exposed lead. Since end consumers are not exposed to lead, lead-free batteries offer numerous benefits (e.g., environmental benefits, health benefits). The example terminals 150A and 150B include one or more annular rings 270, protrusions, or ribs to help secure the corresponding male connector (e.g., plug, pin, fork, etc.). For example, the corresponding connector may have an annular groove that can be positioned or spaced in the connector to mate with the annular ring 270. Alternatively, the terminals may include an annular groove, and the connector may include an annular ring.

[0047] like Figure 18 and Figure 19 In the example shown, the annular ring 270 has substantially flat upper and lower surfaces 275, 280 and a curved surface 285 extending between the upper and lower surfaces 275, 280. In the example shown, the lower surface 280 of one of the annular rings 270 is flush with the bottom surface 272 of the terminals 150A, 150B. The annular ring 270 can have any other suitable shape.

[0048] As mentioned above Figures 13 to 15 As described, the example terminals 150A and 150B are located in a recessed portion 215 on the battery cover 130 relative to the upper surface of the battery cover 130. The recessed region 215 can be of any suitable shape. Figure 18 and Figure 19 In the examples shown, the recessed portion 215 is square or rectangular. One or more corners may be rounded. In some examples, the terminals 150A and 150B may be off-center on the recessed portion 215. In the example shown, the top edge 290 of the terminals 150A and 150B protrudes relative to the recessed portion 215 of the battery cover 130. Furthermore, the top edge 290 shown is made of plastic and may be integrated with the cover 130. Alternatively, the top edge 290 of the terminals may be flush with the recessed portion 215 of the cover 130.

[0049] Figure 20 and Figure 21 Example terminals 150A and 150B are depicted, for example. Figures 13 to 15 Cross-sectional view of any of the example terminals 150A and 150B. Figure 20 and Figure 21 Example terminals 150A and 150B have threads 300 to receive a threaded male connector. In some examples, the threaded portion 300 also includes a keyed portion 305. Similar to... Figures 13 to 15 The concave part, in Figure 20 and Figure 21 The recessed region 215 adjacent to the terminals 150A and 150B is substantially rectangular with rounded edges 310. In some examples, the edges 310 of the recessed portion 215 may be keyed 315 to ensure a secure connection between the connector and the terminals 150A and 150B. In the illustrated example, the key 315 adjacent to the recessed portion 215 includes one or more protrusions extending from the edges 310 of the recessed portion 215.

[0050] In such Figure 20In the example terminals 150A and 150B shown, terminals 150A and 150B include an internal portion 325 with threads 300 and a peripheral portion 330 connecting the internal portion 325 to the cover 130. In some examples, the internal portion 325 is a lead-free metal (e.g., aluminum, steel, copper, brass, etc.). The top edge 335 of the internal portion 325 extends within the peripheral portion 330 to a position near the top edge 340 of the peripheral portion. In some examples, the peripheral portion 330 may contain lead, while in other examples, the peripheral portion 330 may be a lead-free metal. The top edges 335 and 340 of the internal portion 325 and the peripheral portion 330 are in a stepped configuration, protruding relative to the recessed portion 215 of the battery cover 130. Furthermore, a portion of the cover 130 surrounds the terminals 150A and 150B and extends over the top edges 335 and 340 of the inner portion 325 and the surrounding portion 330, but does not enclose the top edges 335 and 340.

[0051] like Figure 21 The example terminals 150A and 150B shown may have a surrounding portion 330 and an inner portion 325 that are similar to those shown. Figure 20 A similar configuration as described. That is, the top edges 335, 340 may also be in a stepped configuration, which protrudes relative to the recessed portion 215 of the battery cover 130. Figure 21 The top edge 340 of the peripheral portion 330 of the example terminals 150A and 150B is enclosed in a plastic cover 130. Specifically, the edge 340 of the peripheral portion 330 extends beyond the top edge 335 of the inner portion 325, and this edge 340 is completely enclosed in the plastic cover 130. Therefore, if the peripheral portion 330 contains lead, Figure 21 The example terminals 150A and 150B described herein do not have any exposed lead.

[0052] Figure 20 and Figure 21 A sleeve 230 electrically connected to the terminals 150A and 150B via a conductive bridge 235 is also depicted, and the sleeve 230 shown is similar to Figure 16 and Figure 17The sleeve shown is illustrated. In the illustrated example, the sleeve 230, the conductive bridge 235, and the surrounding portions of the terminals 105A and 150B can be made of the same material, i.e., leaded or lead-free metal. The example sleeve 230 and its surrounding portions may include one or more annular arrowhead features 345 to ensure a safe, leak-free structure within the battery cover 130. Furthermore, the bottom of the surrounding portions of the terminals may include serrated portions 265 to prevent rotation or torsion of the terminals 150A and 150B. The sleeve 230 is to contact an inner post, which is electrically connected to the electrodes of one or more battery cells in the battery. Figures 13 to 15 As shown, a cover or cap may be placed over the example opening 350 of the sleeve 230. The example cover or cap may include a recess corresponding to the top edge 355 of the sleeve 230, the recess extending slightly above the lowest step of the battery cover 130 surrounding the sleeve 230, such that the cover or cap securely engages with the opening 350 of the sleeve 230. In some examples, the cover 130 with the sleeve 203 and conductive bridge 235 may be adapted to lead-acid batteries with conventional terminals to make the connection between the terminals and connectors described herein more robust, and / or to eliminate any lead exposure in the battery. Batteries without lead exposure offer numerous benefits (e.g., environmental benefits, health benefits) due to the absence of the possibility of lead exposure to the end consumer. Lead exposure can have many adverse side effects, and the example battery without lead exposure eliminates the risk of those adverse side effects that lead exposure might pose to consumers. Any lead-exposed surface in the environment is a potential source of pollution. Therefore, batteries without lead exposure are also beneficial to the environment.

[0053] Detailed embodiments are disclosed herein. However, it should be understood that the disclosed embodiments are intended to be illustrative only. Therefore, the specific structural and functional details disclosed herein should not be construed as limiting, but merely as the basis for the claims and as a representative basis for teaching those skilled in the art to employ the aspects herein differently in virtually any suitable detailed structure. Furthermore, unless expressly stated otherwise, the terms and phrases used herein are not intended to be limiting, but rather to provide an understandable description of possible embodiments. Various embodiments are shown in the figures, but the embodiments are not limited to the illustrated structures or applications.

[0054] For example, an element illustrated as integrally formed may be composed of multiple parts, or an element illustrated as multiple parts may be integrally formed; the operation of the interface may be reversed or otherwise varied; the length or width of the structure and / or components, connectors, or other elements of the system may vary; and the nature or number of adjustment positions provided between elements may vary (e.g., by changing the number or size of the engagement slots or the engagement type). The order or sequence of any process or method steps may be changed or reordered according to alternative embodiments. Other substitutions, modifications, alterations, and omissions may be made to the design, operating conditions, and layout of various embodiments without departing from the spirit or scope of the invention.

[0055] The terms "a" and "one" as used herein are defined as one or more. The term "multiple" as used herein is defined as two or more. The term "another" as used herein is defined as at least a second or more. The terms "including" and / or "having" as used herein are defined as including (i.e., open-ended language). The phrase "at least one of ... and ..." as used herein refers to and includes any and all possible combinations of one or more of the related listed items. As an example, the phrase "at least one of A, B, and C" includes only A, only B, only C, or any combination thereof (e.g., AB, AC, BC, or ABC).

[0056] In this disclosure, the term "coupled" refers to the direct or indirect connection between two components. Such a connection can be fixed or movable in nature. This connection can be achieved by the two components, or two components and any additional intermediate components, forming a single unit, or by the connection of two components, or two components and any additional intermediate components, to each other. Such a connection can be inherently permanent, or inherently detachable or releasable.

[0057] The terms fixed, non-fixed, and movable, as well as their variations, may be used herein. The term fixed and its variations refer to making an object secure, stable, or stationary. However, it should be understood that fixed does not necessarily mean permanent—on the contrary, fixed simply means that a large or abnormal amount of work is required to remove the object from its fixed position. The term "movable" and its variations refer to the ease with which a location, position, or stance can be changed. Here, movable is the antonym of fixed. Additionally, the term non-fixed can also be used as the antonym of fixed.

[0058] The technical effects and problems described in this specification are exemplary and not restrictive. It should be noted that the embodiments described in this specification may have other technical effects and can solve other technical problems.

[0059] Various aspects of this document may be embodied in other forms without departing from its spirit or essential attributes. Therefore, reference should be made to the following claims rather than the foregoing description, as indicated by its scope.
