Description

[0001] Cross-reference to related applications

[0002] This application claims the benefit and priority of U.S. Provisional Application No. 63 / 796,876, filed April 29, 2025, which is incorporated herein by reference in its entirety. Technical Field

[0003] This disclosure generally relates to power systems and related apparatus, and particularly to methods for making or locking mechanical connections between modules of such systems and apparatus. Background Technology

[0004] Providing electricity to a construction site is difficult, especially when there are no existing power lines. The conventional solution is to bring a gas generator to the site. However, there are problems associated with using gas generators, such as smoke and noise emissions, making them suitable only for outdoor use. Furthermore, once installed outdoors, long extension cables must be laid from the generator to the work site, creating tripping hazard. These issues make gas generators a nuisance and potential safety risk on construction sites. Summary of the Invention

[0005] Embodiments of this disclosure address problems associated with the use of gas generators. In particular, embodiments of this disclosure relate to a portable power ecosystem with discrete, modular components that allow users to build precise portable power systems to meet their unique needs. Embodiments of the currently disclosed ecosystem include multiple components such as battery cells, a power management unit (with an internal inverter and charger, AC and DC outputs), a battery charger for various battery voltages, and a base plate and wall-mount plate. Embodiments of the currently disclosed portable power ecosystem provide scalable battery capacity and more efficient DC-DC charging when charging the battery pack.

[0006] As will be discussed more fully below, the discrete modular components utilize wedge-shaped elements and recessed joints (e.g., PACKOUT available from Milwaukee Electric Tool Corporation, Brookfield, WI).

In one or more embodiments, the discrete modular components are stackable and include parts such as toolboxes, portable tools, and power tools. Advantageously, the disclosed platform is a robust and easy-to-operate method for stacking, connecting, and disconnecting different products using the same wedge and recess joints. By utilizing this existing, recognized, and popular wedge and recess joint for mechanical connection in the portable power ecosystem, the newly disclosed electrical module can be adopted and integrated into existing wedge and recess joint products to expand the capabilities of the wedge and recess joint platform.

[0043] Referring generally to the accompanying drawings, various embodiments of a portable power system with modified wedge-shaped members and recessed joints, as well as related devices, are provided.

[0044] In a specific embodiment, the portable power system and related devices include a coupling mechanism (e.g., a convex coupling member and / or a concave coupling member) configured to engage with units of a modular storage system, such as a modular or stackable tool storage system, a modular field storage system, a modular transport storage system, etc.

In various embodiments, the convex and concave connectors described herein and shown in the accompanying drawings are compatible with the connection mechanism described in International Patent Publication No. WO 2017 / 191628, which is incorporated herein by reference in its entirety. In various embodiments, the concave and convex connectors described herein engage with each other to rigidly connect various components including such a connection structure together.

[0047] Additional details are shown and described in the accompanying drawings.

[0048] In order to introduce certain concepts related to the portable power ecosystem, combined with Figures 1A to 1OThe following description provides for the connection and disconnection between the two wedge and recessed engagement modules 10A and 10B. This description generally applies to any wedge and recessed module, such as the PACKOUT available from Milwaukee Electric Tool Corporation (Brookfield, WI). TM The module includes modules of the portable power ecosystem described below. For the purposes of the following discussion, in the connection and disconnection scenarios, the bottom module 10B is static, while the top module 10A is dynamic.

[0049] like Figures 1A to 1E As shown, connecting the two modules 10A and 10B together involves two steps: module descent ( Figures 1A to 1B ) and module sliding ( Figures 1C to 1E In the current publicly available portable power ecosystem, modules can be, for example, battery cells, inverters, or chargers, as well as other possibilities. Figures 1A to 1B During the module lowering step, the user aligns the array of wedges 12 of the top module 10A with the corresponding array of wedge recesses 14 of the bottom module 10B on the X and Z axes. According to this disclosure, a "wedge" is a separate rigid geometry extending from the bottom surface 16 of some modules 10A, 10B, configured to mate with the wedge recesses 14 of another module 10A, 10B. According to this disclosure, a "wedge recess" is a separate rigid geometry serving as a cavity extending into the top surface 18 of some modules 10A, 10B, configured to receive a corresponding wedge 12 of another module 10A, 10B. Specifically, in Figures 1A to 1B During the descent step, the wedge 12 will sit in the front half of the corresponding wedge recess 14. The user translates the top module 10B in the -Y direction until the wedge 12 contacts the bottom of the wedge recess 14. Once positioned in the wedge recess 14, further Y translation, X rotation, and Z rotation are constrained.

[0050] exist Figures 1C to 1E During the module sliding step, the user translates the top module 10A in the -Z direction to lock the wedge 12 into the wedge recess 14. Specifically, at least one protrusion 20 extends over a portion of each wedge recess 14 and engages with the wedge 12. In one or more embodiments, each wedge recess 14 includes two protrusions 20 extending over two corners of the wedge recess 14. When the top module 10A slides such that the wedge 12 translates within the wedge recess 14 in the -Z direction, the protrusions 20 fill the negative space 22 of the wedge 12 (e.g., ...). Figure 1E(As shown). Although the discussion pertains to a single wedge 12 within the corresponding wedge recess 14, the entire array of wedges 12 on the bottom surface 16 of the top module 10A will simultaneously engage the entire array of wedge recesses 14 on the top surface 18 of the bottom module 10B. The interaction between the array of wedges 12 and the array of wedge recesses 14 constrains X-translation and Y-rotation.

[0051] In one or more implementations, such as Figures 1F to 1K As shown, each module 10A, 10B includes a locking mechanism 24 configured to engage adjacent modules 10A, 10B to prevent accidental reverse translation in the +Z direction. Specifically, when the top module 10A translates in the -Z direction, a spring-loaded locking protrusion 26 of the top module 10A is pressed as it slides over the chamfered edge 28 of the bottom module 10B. For example, in… Figure 1F As shown, the wall 30 of each module 10A, 10B includes a sliding channel 32, and a locking protrusion 26 is configured to translate vertically in the Y direction within the sliding channel 32. A first end 34 of the sliding channel defines a first seat for one end of a compression spring 36. The locking protrusion 26 includes a corresponding seat 38 for the opposite end of the compression spring 36. The compression spring 36 biases the locking protrusion 26 in an extended position (i.e., biases the locking protrusion in the -Y direction).

[0052] An opening in the bottom surface 16 is located at the second end 40 of the sliding channel 32, such that the locking protrusion 26, in its deployed state, extends from the sliding channel 32 and beyond the bottom surface 16. Therefore, as mentioned, during sliding, the overhanging end 42 of the locking protrusion 26 engages the chamfered edge 28 of the bottom module 10B. In one or more embodiments, the overhanging end 42 includes a chamfered surface 44 configured to slide against the chamfered edge 28 of the bottom module 10B.

[0053] The wall 30 of modules 10A and 10B includes a first opening 46, and the locking protrusion 26 includes a second opening 48 or a recess. To manually move the locking protrusion 26 against the biased movement of the compression spring 36, a user can insert one or more fingers through the first opening 46 and into the second opening 48 or recess of the locking protrusion 26. The user can then move the locking protrusion 26 by pulling against the edge of the second opening 48 or recess.

[0054] In one or more embodiments, the first aperture 46 defines the range of movement (translation in the Y direction) of the locking protrusion 26. Specifically, the second aperture 48 or recess may define an opening smaller than the first aperture 46, and the second aperture 48 or recess may include a peripheral flange 50 that engages with the peripheral edge 52 of the first aperture 46. That is, the locking protrusion 26 can move against the bias of the compression spring 36 in the +Y direction until the peripheral flange 50 engages with the top of the peripheral edge 52 of the first aperture 46, and the locking protrusion 26 can move against the bias of the compression spring 36 in the -Y direction until the peripheral flange 50 engages with the bottom of the peripheral edge 52 of the first aperture 46.

[0055] As the top module 10A continues to translate along the -Z direction, the locking protrusion 26 slides against the chamfered edge 28, causing the locking protrusion 26 to gradually translate along the +Y direction until the locking protrusion 26 reaches the top surface 18 of the bottom module 10B. Figure 1G and Figure 1H As shown, modules 10A and 10B have recesses 54 formed on their top surfaces 18 for locking the overhanging ends 42 of the protrusion 26. When the locking protrusion 26 is aligned with the recesses 54, the biasing of the compression spring 36 causes the locking protrusion 26 to translate along the -Y direction until the overhanging ends 42 are seated within the recesses 54, as shown. Figure 1I As shown in the diagram, the locking protrusion 26 is seated in the recess 54, constraining the Z-translation, so that all degrees of freedom are constrained, and the two modules 10A and 10B are connected.

[0056] Disconnecting the two modules 10A and 10B involves three steps: raising the locking protrusion 26, sliding the top module 10A, and raising module 10A, as follows. Figures 1J to 1O As shown in the diagram, in the step of lifting the locking mechanism 26, the user inserts one or more fingers through the first hole 46 and into the second hole 48 or the recess to pull the locking protrusion 26 in the +Y direction, thereby disengaging the overhanging end 42 of the locking protrusion 26 from the recess 54, as shown in the diagram. Figure 1J and Figure 1K As shown in the diagram. This provides the first degree of freedom, namely +Z translation, and allows the top module 10A to slide.

[0057] As the locking protrusion 26 is raised, the sliding of the top module 10A begins. (As...) Figure 1L and Figure 1M As can be seen, the user slides the top module 10A along the +Z direction until the array of wedges 12 disengages from the protrusions 20 of the corresponding array of wedge recesses 14 and the wedges 12 are positioned in front of the wedge recesses 14. Finally, as... Figure 1N and Figure 10As shown, the user lifts the top module 10A upwards (by translating +Y) to separate the top module 10A from the bottom module 10B. In this way, once the wedge 12 of the top module disengages from the wedge recess 14 of the bottom module 10B, the two modules 10A and 10B are disconnected.

[0058] The mechanical interactions that lock modules 10A and 10B together have been described; now, aspects of the mechanical engagements for facilitating or locking the electrical connection between modules 10A and 10B are described. Each aspect includes information about... Figures 1A to 1O Some or all of the components described for forming mechanical interactions are shown, and these components will be identified by the same reference numerals (unless otherwise specified). Generally, each module, regardless of the aspect for forming electrical connections, is, for example, a battery cell, inverter, power management unit, or charger, and other possibilities include electrical and electronic components required to achieve these functions.

[0059] According to embodiments of this disclosure, such as Figure 2A As shown, the bottom module 10B includes a feature, particularly a channel 60, extending through the wedge-shaped recess 14 on the top surface 18. In one or more embodiments, the channel 60 extends throughout the Z-direction at the wedge and recess junction. Figure 2A In the embodiment shown, the two channels 60 are positioned at a half-width shape factor (relative to a typical PACKOUT). TM (Module system). In one or more other embodiments, the bottom module 10B may alternatively include one channel 60 or three or more channels 60, such as up to five channels 60. According to embodiments of this disclosure, such as Figure 2B As shown, the top module 10A includes a corresponding feature, such as a track 62, extending through the wedge 12 on the bottom surface 16. In one or more embodiments, the track 62 extends the entire Z-direction over the wedge and recess engagement. Figure 2B In the illustrated embodiment, two tracks 62 are positioned on the half-width shape factor. In one or more other embodiments, the top module 10A may alternatively include one track 62 or three or more tracks 62, such as up to five tracks 62. As will be discussed more fully below, the number of channels 60 on each corresponding bottom module 10B and the number of tracks 62 on the top module 10A can be used to create unique joints, wherein certain combinations of bottom modules 10B and top modules 10A are compatible, while others are incompatible.

[0060] In various embodiments of the bottom module 10B and the top module 10A, a corresponding channel 60 or track 62 extending through the wedge recess 14 or the wedge 12 may or may not exist. When the channel 60 or track 62 does not exist, the wedge and recess engagement is not modified, as... Figure 2C and Figure 2E As shown. When "present", the corresponding bottom module 10B includes channel 60, as shown. Figure 2D As shown, and the corresponding top module 10A includes track 62, as Figure 2F As shown in the diagram. For simplicity, in the following discussion, the "presence" or "absence" of channel 60 or track 62 will be referred to only as the numbers 1 and 0, respectively. That is, respectively, a "0" on top module 10A and bottom module 10B indicates that the unmodified wedge and recessed joint of channel 60 or track 62 is absent, and a "1" on top module 10A and bottom module 10B indicates that the modified wedge and recessed joint of track 62 and channel 60 is present.

[0061] There are four possible interactions between channel 60, track 62, the unmodified wedge 12 on top module 10A, and the unmodified wedge recess 14 on bottom module 10A. According to the first interaction, channel 60, passing through wedge recess 14 in bottom module 10B, interacts with the unmodified wedge 12 in top module 10A. As... Figure 2G As shown, this interaction is a compatible wedge and recess engagement for the bottom module 10B and the top module 10A. In particular, there is no structure that hinders the interaction between the wedge 12 and the wedge recess 14, thus resulting in the formation of a general wedge and recess engagement.

[0062] According to the second interaction, the channel 60 passing through the wedge-shaped recess 14 of the bottom module 10B interacts with the track 62 passing through the wedge-shaped member 12 of the top module 10A. As... Figure 2H As shown, this interaction is a compatible wedge and recess engagement for the bottom module 10B and the top module 10A. In particular, the track 62 of the wedge 12 extending through the top module 10A is capable of sliding through the channel 60 of the wedge recess 14 in the bottom module 10B.

[0063] According to the third interaction, the unmodified wedge-shaped recess 14 of the bottom module 10B interacts with the unmodified wedge 12 of the top module 10A. This is the above regarding... Figures 1A to 1O The generally described wedge-shaped member and recessed joint.

[0064] According to the fourth and final interaction, the unmodified wedge-shaped recess 14 of the bottom module 10B interacts with the track 62 of the wedge-shaped member 12 extending through the top module 10A. As... Figure 2I As can be seen, the wedge 12 cannot be seated in the wedge recess 14 because the track 62 prevents the wedge 12 from translating in the -Y direction within the wedge recess 14. Therefore, the combination of the unmodified array of wedge recesses 14 on the bottom module 10B and the modified wedge 12 with track 62 on the top module 10A provides an incompatible wedge and recess engagement, thereby locking the engagement between the top module 10A and the bottom module 10B.

[0065] The interaction of the aforementioned channel 60, track 62, unmodified wedge 12, and unmodified wedge recess 14 results in modules 10A and 10B being connected together or locked to each other. According to the discussion below, if the features allow modules 10A and 10B to be connected together, the interaction between modules 10A and 10B is "compatible," and if the features do not allow modules 10A and 10B to be connected together or locked, the interaction is "incompatible." The four possible interactions discussed above are summarized in Table 1 below.

[0066] Table 1 Interactions between modules

[0067]

[0068] The preceding discussion focused on the interaction between one channel 60 and one track 62 in each module 10A, 10B; however, each module 10A, 10B may have multiple tracks 62 and / or multiple channels 60. For the purposes of this disclosure and the following description, the half-width wedge and recessed joint shape factor will be the “basic unit” used for code numbering description. According to some commercial implementations, the half-width shape factor is used for PACKOUT. TM The product's smallest wedge array, and therefore, when describing the various joint codes below, the joint description will be based on this shape factor. For example... Figure 2A and Figure 2B As shown, the half-width array has two columns of wedges 12 and wedge recesses 14, and the number of digits in the joint code will be twice the number of features in each recess. That is, the code describing one feature of each recess will have two digits, the code describing two features of each recess will have four digits, and so on. For the purposes of this disclosure, the full-width product will have the same repeating code, which is essentially considered a double half-width.

[0069] In one or more embodiments, directionality is considered when interpreting the code. When reading code corresponding to the top surface 18 of the bottom module 10B, the code will correspond to the top surface 18 of module 10B, which is oriented such that the recess 54 is located at the top, as... Figure 3A As shown in the image. Then, read the code from left to right. Regarding... Figure 3A The code "01" shown in the exemplary embodiment would mean that the wedge recess 14 in the left column is "0", that is, it does not have a channel 60 extending through the wedge recess 14 in the left column, and the wedge recess 14 in the right column is "1", that is, it has a channel 60 extending through the wedge recess 14 in the right column.

[0070] When the code corresponding to the bottom surface 16 of the top module 10A is read, the bottom surface 18 is oriented such that the locking protrusion 26 is located at the bottom, as... Figure 3B As shown in the image. Then, read the code from left to right. Regarding... Figure 3B The exemplary embodiment shown in code "1010" includes two potential locations for the track 62 in each column of wedges 12. Thus, in the left column of wedges 12, "1" corresponds to having the track 62, and "0" corresponds to not having the track 62. In the right column of wedges 12, "1" again corresponds to having the track 62, and "0" corresponds to not having the track 62. In this way, each individual channel 60, track 62, and the interaction of the wedges and recesses must be "compatible" for connecting the two modules 10A, 10B together. Even a single "incompatible" interaction means that modules 10A, 10B will not be able to connect together; that is, modules 10A, 10B will be mechanically locked to each other. As discussed above, the module connection is "compatible" when modules 10A, 10B are allowed to connect together, and "incompatible" if modules 10A, 10B are restricted from connecting to each other.

[0071] At the threshold level, the mating joints between the top module 10A and the bottom module 10B should have the same number of digits in the joint code, and the codes can then be compared to see if any corresponding digits between the codes would prevent the combination. As discussed above, all digits in each code must be compatible to make the joint compatible. A single incompatibility between the digits of the corresponding codes will mechanically lock the top module 10A, preventing it from sitting in the bottom module 10B.

[0072] In one or more embodiments, the minimum number of features for each wedge 12 or wedge recess 14 is one, and each half-width joint has a total of two features. This results in four possible joints for the top surface 18 of the bottom module 10B and four possible joints for the bottom surface 16 of the top module 10A, for a total of 16 unique mating joints. Figure 4 A table summarizing the compatibility of 16 mating joints is provided. Figure 4 The table also provides a "compatibility percentage" value associated with each joint. The compatibility percentage is a value calculated for each joint and refers to the percentage of joints that can be connected to a given joint. A higher compatibility percentage means more joints can be connected to the given joint, while a lower compatibility percentage means fewer joints can be connected to the given joint.

[0073] from Figure 4 As can be seen, both the top surface 18 of the bottom module 10B and the bottom surface 16 of the top module 10A include the potential codes "11", "01", "10", and "00". The "11" joint on the top surface 18 of the bottom module 10B and the "00" joint on the bottom surface 16 of the top module 10A both have a 100% compatibility percentage because these joints can match any other joint type. In contrast, the "00" joint on the top surface 18 of the bottom module 10B is only compatible with the "00" joint on the bottom surface 16 of the top module 10A, and the "11" joint on the bottom surface 16 of the top module 10A is only compatible with the "11" joint on the top surface 18 of the bottom module 10B. Therefore, these two joints have a 25% compatibility percentage. The remaining two joints “01” and “10” of each of the top surface 18 of the bottom module 10B and the bottom surface 16 of the top module 10A each have a 50% compatibility percentage, thereby engaging with the “11” joint and the corresponding “01” or “10” joint of the opposite modules 10A and 10B.

[0074] The number of channels 60 and tracks 62 for each corresponding column of wedge recesses 14 and wedges 12 can be increased to provide more locking combination options. If the number of features for each wedge recess 14 or wedge 12 is increased to two, then each half-width joint is provided with a total of four channels 60 or tracks 62, resulting in 16 possible joints for the top surface 18 of the bottom module 10B, 16 possible joints for the bottom surface 16 of the top module 10A, and a total of 256 possible unique mating joints. Figure 5A and Figure 5B A table summarizing the compatibility of 256 unique mating joints and the compatibility percentage of each corresponding joint in the bottom module 10B and top module 10A is provided.

[0075] Based on the system's requirements and complexity, and the number of components that need to be controlled when stacked, the designer can determine the required number of unique top / bottom joint interactions. This can also be quantified using Equation 1 below, where the number of unique top / bottom joint interactions is a function of the number of features in each recess on the half-width module.

[0076] Q = ((2 n ) 2 ) 2 (1)

[0077] Where Q is the number of unique mating joints, and n is the number of channels 60 or tracks 62 in each row of wedge recesses 14 or wedges 12. The number of unique mating joints (Q) can rapidly increase as the number (n) of features in each wedge recess 14 or wedge 12 increases. As shown in Table 2 below, the five features of each wedge recess 14 or wedge 12 provide more than one million unique mating joints for the top module 10A and the bottom module 10B.

[0078] Table 2. Number of unique mating joints based on features

[0079]

[0080] For the top surface 18 of the bottom module 10A and the bottom surface 16 of the top module 10B, the compatibility percentage of the joint can be calculated using Equations 2 and 3 below, respectively.

[0081] C T = 2 x / n 2 (2)

[0082] C B = 2 (n-x) / n 2 (3)

[0083] Among them, C T This is the compatibility percentage for the top surface 18 of the bottom module 10B, C. Bis the compatibility percentage for the bottom surface 16 of the top module 10A, x is the number of features (channels 60 or tracks 62) present in the joint (i.e., the number of "1"s in the joint code), and n is the total number of features (channels 60 or tracks 62) in the joint (i.e., the total number of digits in the joint code). Knowing the compatibility percentage can be helpful when designing modules 10A and 10B with a certain degree of compatibility. For example, by selecting a design with a higher compatibility percentage based on Equations 2 and 3, the module can be designed to be more compatible with other modules. Conversely, by selecting a design with a lower compatibility percentage, the module can be designed to mechanically lock with most other modules.

[0084] As will be understood from the foregoing discussion, it is advantageous to design modules 10A and 10B to restrict stacking in certain configurations. That is, by using the mechanical locking joints according to this disclosure, the placement of modules on or within a stack can be controlled without unduly limiting the potential future iterations of the module ecosystem.

[0085] While allowing full compatibility between various modules within wedge and recessed joint systems offers benefits, there may also be reasons to limit or completely prohibit compatibility between certain stacking configurations or modules. For example, it might be desirable to limit compatibility between older generation modules and newer generation modules, where such combinations could create hazards or affect system operability. As another example, heavier modules within an ecosystem could be designed with joint compatibility that confines the module to a lower position within the stack, preventing the stack from unintentionally becoming top-heavy, which could lead to tilting. Furthermore, certain ecosystem components could be designed with joints compatible with stacking onto existing mobile or mounting structures, such as rolling toolboxes, mounting plates, or trolleys. Additionally, modules can be designed to stack in configurations that avoid impossible or impractical designs, focusing instead on optimizing the performance of the modules within the stack. In this way, users are prevented from building restricted stacks, thereby improving the user experience and reducing the clutter caused by inoperable stacks.

[0086] Figure 6A and Figure 6BThe illustration shows two stacked modules, illustrating the potential limitations of a stacking configuration based on mechanical locking. As can be seen, each stack includes a battery cell 70, a power sustaining unit (PMU) 72, and a power tool battery charger 74. The battery cell 70 and PMU 72 have full-width joints, and the battery charger 74 has a half-width joint. According to the exemplary system, it is desirable for the battery cells 70 to be grouped together and located at the bottom of the stack. The PMU 72 is placed on top of the battery cells 70, and the battery charger 74 is placed on top of the battery cells 70 and PMU 72. Within the system, other wedge-shaped and recessed modules may be placed on top of the battery cells 70 and PMU 72, but not on top of the battery charger 74. Furthermore, other wedge-shaped and recessed modules may be positioned below the battery charger 74, but not below the battery cells 70 or PMU 72. As shown in Figure 6A, a first mating joint 76 between the battery cells allows one battery cell 70 to be stacked on top of another battery cell 70. The second mating joint 78 between the topmost battery cell 70 and PMU 72 allows PMU 72 to be stacked on top of battery cell 70, and the third mating joint 80 between PMU 72 and battery charger 74 allows battery charger 74 to be stacked on top of PMU 72.

[0087] In one or more embodiments, the battery cell 70 may have a joint code 1111 on its top surface and a joint code 1111 on its bottom surface. For example... Figure 5A and Figure 5B As shown, the engagement code 1111 on the bottom surface is only compatible with the engagement code 1111 on the top surface, thereby preventing the battery cell 70 from being stacked on another module by means of mechanical locking. Therefore, the first mating engagement 76 is located between the top surface and the bottom surface having the engagement code 1111.

[0088] In one or more embodiments, PMU 72 may have a joint code 0000 for the bottom surface and a joint code 0101 for the top surface. For example... Figure 5A and Figure 5B As shown, the engagement code 0000 on the bottom surface of PMU 72 is compatible with the engagement code 1111 on the top surface of battery cell 70, such that the second mating engagement 78 corresponds to the top surface engagement 1111 and the bottom surface engagement 0000 (i.e., the standard wedge and recess design).

[0089] In one or more embodiments, the battery charger 74 includes a mating code 00 on its bottom surface. As mentioned, the battery charger 74 in this example embodiment is a half-width structure, and therefore, placing two battery chargers 74 side by side would essentially correspond to mating code 0000 (each half being a standard wedge and recess design). The mating portion 0101 on the top surface of the PMU 72 is compatible with the 0000 mating portion defined by the bottom surface of the battery charger 74, thereby making the third mating mating portion 80 correspond to the top surface mating portion 0101 and the bottom surface mating portion 0000. To prevent stacking on top of the battery chargers 74, no wedge recess is provided on the top of the battery charger.

[0090] like Figure 6B As shown, the described top surface joint and bottom surface joint prevent certain stacking configurations. While the 1111 joint on the top surface of the battery cell 70 allows stacking of a battery charger 74 with a bottom surface having a 0000 joint, the lack of a wedge-shaped recess on the top of the battery charger 74 prevents the stacking of any other modules on the battery charger. Furthermore, while the mating joints 0101 on the top surface and 0000 on the bottom surface allow one PMU 72 to be stacked on top of another PMU 72, the battery cell 70 is not allowed to be stacked on top of a PMU 72 because the bottom surface joint 1111 on the battery cell 70 is incompatible with the top surface joint 0101 of the PMU 72.

[0091] In addition to or in lieu of the modifications to the wedge and recess engagement described above, modules 10A and 10B can be configured to provide another feature, such as different insertion distances when the two modules 10A and 10B are engaged together. For electrical modules 10A and 10B, the electrical engagements are typically also connected by translation along an axis until all contacts are connected to their corresponding contacts in the mating engagement. Examples of suitable mechanisms for forming an electrical connection between modules 10A and 10B can be found in International Patent Application No. PCT / US2025 / 030369, filed May 21, 2025, the entire contents of which are incorporated herein by reference. Users tend to prefer forming both mechanical and electrical connections in the same movement. Some commercially available modules with wedge and recess engagements have an insertion distance of 26 mm, which is limited by the geometry of the wedge and wedge recess. This is the distance the top module translates along the Z direction to engage in place. If the electrical connection is located at one end of the module, the electrical connection can be performed simultaneously with the mechanical connection. The difficulty of forming an electrical connection is limited by the 26 mm insertion distance. In particular, the required insertion distance for the electrical connection depends on a variety of factors, including contact insertion timing, entry and contamination requirements, and terminal float. As will be discussed more fully below, the connection between modules 10A and 10B, defined by wedge 12 and wedge recess 14, is enlarged relative to the conventional 26 mm insertion distance, thereby providing a greater distance for full mating and meeting a variety of other operational requirements.

[0092] Figure 7AAn embodiment depicting a first geometry of the wedge-shaped recess 14 is provided, wherein the wedge-shaped recess 14 is a long, continuous recess in the Z direction, compared to a series of, for example, three shorter wedge-shaped recesses as shown and described in the various embodiments above. In one or more embodiments, the bottom module 10B includes a cover 82 defining a top surface 18. The cover 82 includes a plurality of sides 84a to 84d, wherein a first side 84a is opposite to a second side 84b, and a third side 84c is opposite to a fourth side 84d. As can be seen, the wedge-shaped recess 14 extends from an opening 86 in the first side 84a toward the second side 84b. The first side 84a and the second side 84b are separated by a distance D. In one or more embodiments, the wedge-shaped recess 14 extends at least 50%, at least 75%, or at least 90% of the distance D from the first side 84a to the second side 84b. Furthermore, in one or more embodiments, the protrusion 20 of the wedge recess 14 extends along at least 50%, at least 60%, or at least 75% of the length of the wedge recess 14. In one or more specific embodiments, the length of the wedge recess 14 is in the range of 200 mm to 250 mm, particularly about 226 mm. Compared to the conventional wedge recess length of 26 mm, the long wedge recess 14 provides a much larger insertion distance for electrical connection when combining modules 10A, 10B.

[0093] Figure 7B An embodiment of a second geometric shape for the wedge-shaped recess 14 is depicted, wherein the wedge-shaped recess 14 is a long, continuous recess in the Z direction, but instead of also having long, continuous wedge-shaped protrusions 20, the wedge-shaped protrusions 20 extend in a variable manner over the negative space of the wedge-shaped recess 14. That is, each wedge-shaped recess 14 includes a plurality of protrusions 20a to 20e, substantially mimicking the three individual wedge-shaped recesses of the conventional embodiment. As can be seen, the intermediate wedge-shaped recess 14 is a double wedge-shaped recess extending from the third side 84c across the top surface 18 to the fourth side 84d.

[0094] Figure 8AAn embodiment of a first geometry of the wedge 12 is depicted, wherein the wedge 12 is a long, continuous wedge 12 in the Z direction, compared to a plurality of discrete wedges arranged in a row as described in the various embodiments above. In one or more embodiments, the bottom module 10B includes a container 88 defining a bottom surface 16. The container 88 includes a plurality of sides 90a to 90d, wherein a first side 90a is opposite to a second side 90b, and a third side 90c is opposite to a fourth side 90d. As can be seen, the wedge 12 extends from near the second side 90b toward the first side 90a. The first side 90a is separated from the second side 90b by a distance D. In one or more embodiments, the wedge 12 extends at least 50%, at least 60%, or at least 75% of the distance D from near the second side 90b toward the first side 90a. When combined with the long, continuous wedge-shaped recess 14, the long wedge 12 provides a much larger insertion distance, for example up to 226 mm, for electrical connection when combining modules 10A, 10B.

[0095] Figure 8B An embodiment of a second geometry of the wedge 12 is depicted, wherein the wedge 12 has a T-shaped configuration. For example... Figure 8B As shown, the wedge 12 includes a central post 92 and a transverse member 94, the transverse member 94 extending across the post 92 such that the transverse member 94 extends through both sides of the post 92. Figure 9A and Figure 9B A comparison is provided with an unmodified wedge compared to T-shaped wedge 12. As can be seen, T-shaped wedge 12 does not include any webbing material 95 positioned below the transverse members 94 on either side of the central post 92, which allows T-shaped wedge 12 to slide within and along the entire length of the wedge recess 14. In one or more embodiments, T-shaped wedge 12 can be compared with... Figure 7A The long, continuous wedge-shaped recess 14 shown is combined with, and as... Figure 7B The wedge-shaped recesses 14 shown are combined with multiple protrusions 20.

[0096] like Figure 7A and Figure 7B The two disclosed wedge-shaped recesses 14 and the conventional wedge-shaped recess shown create three possibilities for the mating joint on the top surface 18 of the bottom module 10B. Similarly, as Figure 8A and Figure 8B The two disclosed wedges 12 and the conventional wedge shown create three possibilities for the mating surface on the bottom surface 16 of the top module 10A. The six combined geometries produce nine possible combinations of the top module 10A and the bottom module 10B, as summarized in Table 3 below.

[0097] Table 3. Combination of wedge-shaped elements and wedge-shaped recesses

[0098]

[0099] The first interaction is between an unmodified wedge and an unmodified recess, which are compatible with each other and have an insertion distance of 26 mm. The second interaction is between an unmodified wedge and a long recess. The two joints are incompatible, such as... Figure 10A As shown in the diagram, the protrusions 20 of the long wedge recess 14 contact the webbing 95 of the wedge 12, thereby preventing the wedge 12 from being further inserted into the wedge recess 14. A third interaction is between the unmodified wedge 12 and the variable wedge recess 12 having multiple protrusions 20a to 20e. These two joints are compatible and connected in the same manner as the unmodified wedge recess, resulting in an insertion distance of 26 mm.

[0100] The fourth interaction is between the long wedge 12 and the unmodified wedge recess, such as... Figure 10B As shown, the long wedge 12 is incompatible with the unmodified wedge recess. Specifically, the long wedge 12 is too large to fit into the wedge recess, thus hindering insertion of the wedge 12 into the wedge recess 14. A fifth interaction is between the long wedge 12 and the long wedge recess 14, which is a compatible joint with an insertion distance of 226 mm. Figure 10C The diagram shows the insertion of a long wedge 12 into a long wedge recess 14. A sixth interaction is between the long wedge 12 and a variable wedge recess 14 having multiple protrusions 20a to 20e. This is also a compatible joint providing an insertion distance of 226 mm, as shown in... Figure 10D As shown in the image.

[0101] The seventh interaction is between the T-shaped wedge 12 and the unmodified wedge recess 14, which is a compatible joint providing an insertion distance of 26 mm. This interaction operates essentially in the same manner as the unmodified wedge 12 and the unmodified wedge recess 14. The eighth interaction is between the T-shaped wedge 12 and the long wedge recess 14. The two joints are compatible and provide an insertion distance of 226 mm, as... Figure 10E As shown in the diagram. The ninth interaction is between the T-shaped wedge 12 and the variable recess 14 having a plurality of protrusions 20a to 20e. These two engagements are compatible and provide an insertion distance of 26 mm, 123 mm, or 226 mm depending on the position of the T-shaped wedge inserted into the variable wedge recess 14. Figures 10F to 10H Various insertion points with different insertion distances are depicted for this interaction. For example... Figure 10FAs shown, the T-shaped wedge 12 closest to the second side 90b of the container 88 is inserted into the portion of the wedge recess 14 closest to the second side 84b of the cap 82, thereby providing the shortest possible insertion distance (e.g., 26 mm). Figure 10G As shown, the T-shaped wedge 12 closest to the second side 90b of the container 88 is inserted into the portion of the wedge recess 14 located between the first side 84a and the second side 84b of the cap 82, thereby providing an intermediate insertion distance (e.g., 123 mm). Figure 10H As shown, the T-shaped wedge 12 closest to the second side 90b of the container 88 is inserted into the portion of the wedge recess 14 closest to the first side 84a of the cap 82, thereby providing the longest insertion distance (e.g., 226 mm).
