Description

Technical Field

[0001] This application belongs to the field of battery technology, specifically relating to a battery device, battery module, energy storage device, and electrical equipment. Background Technology

[0002] As battery devices are increasingly used in vehicles, ships, energy storage systems, and construction machinery, they often need to be electrically connected to the outside via electrical connectors to enable charging, discharging, or communication.

[0003] In related technologies, electrical connectors are typically located near the side walls of the enclosure assembly. The wiring harness is led out from the connector's terminal and then connected to external wiring. The metal flanges used for connecting the upper and lower housings often have a certain protrusion height, and their edges, flanges, or welded areas may form relatively obvious ridge structures. When the wiring harness is subjected to vibration, shaking, or external pulling, it is easy for the harness to swing around and come into contact with the flanges. Especially in environments with continuous vibration or impact, such as vehicles and ships, repeated friction may occur between the wiring harness and the connecting flanges, leading to wear on the outer sheath of the wiring harness, damage to the insulation layer, and even safety hazards such as leakage, short circuits, or arcing. Utility Model Content

[0004] This application aims to provide a battery device, battery assembly, energy storage device, and electrical equipment to solve the problem of easy contact, friction, and wear between the wiring harness and the connection fold of the side wall near the terminal.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, embodiments of this application propose a battery device, which includes a housing assembly, the housing assembly including a bottom shell and a top cover connected to each other, a connecting flange being provided at the connection between the bottom shell and the top cover, and the connecting flange being located on the side wall of the housing assembly; a mounting boss fixedly connected to the outer surface of the side wall of the housing assembly, the mounting boss protruding outward in a direction away from the interior of the housing assembly; and an electrical connector fixedly connected to the mounting boss, with the wiring port of the electrical connector located on the side of the mounting boss away from the housing assembly; wherein, in a direction perpendicular to the side wall of the housing assembly, the protrusion height of the mounting boss relative to the outer surface of the side wall is greater than the protrusion height of the connecting flange relative to the outer surface of the side wall, so that a gap is formed between the wire harness connected to the electrical connector and the connecting flange.

[0007] The battery assembly includes a housing assembly, mounting bosses, and electrical connectors. By altering the positional relationship between the electrical connector and the wiring harness relative to the sidewalls of the housing assembly and the connecting flange, a gap is created between the wiring harness connected to the electrical connector and the connecting flange. This reduces contact and friction between the wiring harness and the connecting flange, lowering the risk of insulation wear, damage, and consequently leakage, short circuits, or arcing. The gap prevents the wiring harness from contacting the connecting flange under normal installation conditions, or makes it less likely for the wiring harness to scratch the connecting flange even under vibration, swaying, or slight tension.

[0008] In this embodiment, the housing assembly is interconnected by a bottom shell and a top cover to form a stable housing structure. A connecting flange is provided at the connection point between the bottom shell and the top cover. While the connecting flange improves the connection strength and sealing reliability of the housing assembly, it also constitutes a risk area for wire harness wear. A mounting boss is fixedly connected to the outer surface of the side wall of the housing assembly and protrudes outwards in a direction away from the interior of the housing assembly, allowing the electrical connector to be mounted protruding outwards. The electrical connector is fixedly connected to the mounting boss, and the connector's terminal is located on the side of the mounting boss away from the housing assembly, ensuring that the wire harness exit point is away from the connecting flange. Furthermore, in a direction perpendicular to the side wall of the housing assembly, the protrusion height of the mounting boss relative to the outer surface of the side wall is greater than the protrusion height of the connecting flange relative to the outer surface of the side wall, so that the wire harness is structurally located in the outer region of the connecting flange, thereby creating a gap between the wire harness and the connecting flange.

[0009] In some embodiments, the top cover and the bottom shell are connected in the height direction, and the opening direction of the wiring port in the electrical connector is set at an angle to the height direction.

[0010] In some embodiments, the bottom shell includes a connecting end face for connecting to the top cover, and the mounting boss includes a first connecting portion for connecting to the side wall of the housing assembly; wherein the mounting surface of the first connecting portion is inclined relative to the connecting end face, and the included angle between the mounting surface of the first connecting portion and the connecting end face is an acute angle or an obtuse angle.

[0011] The connecting end face provides an assembly reference for the connection between the bottom shell and the top cover. The first connecting part provides a fixed base for the connection between the mounting boss and the side wall of the housing assembly. The mounting surface of the first connecting part is inclined relative to the connecting end face, allowing the mounting boss to be installed at an angle on the side wall of the housing assembly. This inclined installation posture changes the positional relationship of the mounting boss, electrical connector, and wiring harness relative to the connection area between the bottom shell and the top cover, making it easier for the wiring harness's exit position and path to avoid the connection folds. Compared to a structure where the mounting surface of the first connecting part is perpendicular to the connecting end face, this solution allows the orientation of the mounting boss to be adjusted according to the wiring harness layout requirements, providing the wiring harness with greater clearance and a smoother extension path.

[0012] In some embodiments, the mounting boss includes a second connecting portion for connecting an electrical connector, wherein the plane on which the mounting surface of the second connecting portion is located is perpendicular to the plane on which the connecting end face is located.

[0013] The connecting end face provides a reference for the connection between the bottom shell and the top cover, and the mounting surface of the second connecting part provides a reference for the installation of the electrical connector. When the plane where the mounting surface of the second connecting part is located is perpendicular to the plane where the connecting end face is located, the electrical connector can form a stable and regular installation posture relative to the connection direction of the bottom shell and the top cover. This is beneficial for the positioning and installation of the electrical connector on the side wall of the housing assembly, reduces the assembly deviation caused by the uncertainty of the mounting surface tilt, makes the position of the electrical connector's wiring port more controllable, and facilitates the wire harness to be led out in a predetermined direction, and helps to maintain the gap between the wire harness and the connecting fold.

[0014] In some embodiments, the mounting boss includes a second connection portion for connecting an electrical connector, wherein the normal direction of the mounting surface of the second connection portion is set at an angle to the normal direction of the sidewall of the housing assembly.

[0015] The second connecting part supports and secures the electrical connector, and can also change the mounting direction of the connector and the opening direction of the connector port by tilting the mounting surface. Since the normal direction of the mounting surface of the second connecting part forms an angle with the normal direction of the side wall of the housing assembly, after the electrical connector is fixed to the second connecting part, the connector port can be tilted relative to the side wall of the housing assembly towards a predetermined direction. This allows the wiring harness to be led out along the tilted direction after being connected to the port, without having to extend directly along a direction perpendicular to the side wall of the housing assembly and then make a sharp bend. This reduces wiring harness bending, lowers internal stress in the wiring harness, and improves the avoidance relationship between the wiring harness and the connecting edge.

[0016] In some embodiments, the battery device further includes: a mounting hole provided on the side wall of the bottom shell, and the mounting hole avoids the connecting flange; wherein, the mounting boss surrounds the outer periphery of the mounting hole, and at least a portion of the electrical connector passes through the mounting hole.

[0017] The mounting hole provides a structural channel for the electrical connector to pass through the side wall of the bottom housing. The mounting hole avoids the connecting flange, maintaining the structural strength and sealing performance at the connection between the bottom housing and the top cover. The mounting boss surrounding the mounting hole reinforces the area around the mounting hole and provides a protruding mounting base for the electrical connector. At least a portion of the electrical connector passes through the mounting hole, enabling electrical connection between the internal electrical connectors of the enclosure assembly and the external wiring harness. Through the cooperation of these three elements, the electrical connector can be stably mounted on the side wall of the enclosure assembly while avoiding the connecting flange, and the wiring harness connected to the electrical connector is kept away from the connecting flange, thus maintaining the gap between the wiring harness and the connecting flange.

[0018] In some embodiments, the electrical connector includes: an external interface end located on the outside of the housing assembly, the external interface end being inclined relative to the side wall of the housing assembly; and an internal interface end located inside the housing assembly, the internal interface end having an internal connection surface, the internal connection surface being parallel to the connection surface of an electrical connector located inside the housing assembly.

[0019] The external interface end is angled relative to the side wall of the enclosure assembly, which optimizes the wiring harness exit direction on the outside of the enclosure assembly, making it easier for the wiring harness to avoid connection folds and extend along a predetermined path. The internal interface end is located inside the enclosure assembly and has an internal connection surface. This internal connection surface is parallel to the connection surface of the electrical connector located inside the enclosure assembly, which optimizes the electrical connection direction inside the enclosure assembly, enabling a straight and stable connection between the internal interface end and the electrical connector. Therefore, the electrical connector can simultaneously meet the requirements of externally angled wiring exit and internally straight wiring, improving the wear resistance of the wiring harness while reducing the assembly difficulty of the electrical connector inside the enclosure assembly.

[0020] In some embodiments, the battery device further includes: a conductive connector, at least a portion of which is disposed within an electrical connector, one end of which is electrically connected to an external interface terminal, and the other end of which is electrically connected to an internal interface terminal, wherein the conductive connector is bent between the external interface terminal and the internal interface terminal.

[0021] Conductive connectors can form an electrical connection path with directional conversion capability between the external and internal interface ends. Since the external interface end can be inclined relative to the side wall of the enclosure assembly to allow external wiring harnesses to exit at an angle and avoid connection folds, while the internal connection surface of the internal interface end can be parallel to the connection surface of the electrical connectors within the enclosure assembly for a straight internal connection, the directions of the external and internal interface ends may not be consistent. By bending the conductive connector between the external and internal interface ends, the inclined external interface and the straight internal interface can be effectively connected, thus simultaneously satisfying the requirements of convenient external wiring harness arrangement and reliable internal electrical connection.

[0022] In some embodiments, the conductive connector is a copper bar, one end of which is located inside the electrical connector and connected to an external interface; the other end of which is located inside the housing assembly and connected to an electrical connector.

[0023] One end of the copper bar is located inside the electrical connector and connected to the external interface, while the other end is located inside the housing assembly and connected to the electrical connector. This allows the copper bar to bridge the electrical connector and the internal electrical connector of the housing assembly, forming a stable, low-impedance, and structurally strong electrical connection path between the external interface and the electrical connector. After the external wiring harness is connected to the external interface, current or signals can be transmitted sequentially through the external interface, the copper bar, and the electrical connector to the electrical system inside the housing assembly. This structure reduces the risks of vibration, fatigue, and poor contact caused by flexible cables transitioning inside the electrical connector, while also improving high-current transmission capacity and vibration resistance reliability.

[0024] In some embodiments, the electrical connector includes a positive connector and a negative connector arranged adjacent to each other, wherein the opening direction of the wiring port of the positive connector is parallel to the opening direction of the wiring port of the negative connector.

[0025] The adjacent placement of the positive and negative connectors centralizes the external interfaces of the battery device, reducing the space occupied and assembly complexity caused by the dispersed arrangement of the positive and negative wiring harnesses on the outside of the housing assembly. The parallel orientation of the openings of the positive and negative connectors allows the positive and negative wiring harnesses to exit the battery device in a parallel or near-parallel configuration. This allows the positive and negative wiring harnesses to extend along the same routing path, facilitating bundling, securing, sheathing, and path planning, and reducing wiring harness crossings, twists, sharp bends, or interference.

[0026] In some embodiments, along a direction perpendicular to the sidewall of the housing assembly, gaps are formed between the terminals of the positive connector and the terminals of the negative connector and the connecting flange, respectively.

[0027] The positive and negative connectors serve as the external interfaces for the positive and negative terminals of the battery device, respectively, and are typically used to connect the positive and negative wiring harnesses. By creating gaps between the terminals of the positive and negative connectors and the connecting folded edges along a direction perpendicular to the side wall of the housing assembly, it is ensured that the initial exit areas of the positive and negative wiring harnesses are far from the connecting folded edges. This prevents the positive and negative wiring harnesses from coming into contact with, scratching, or repeatedly rubbing against the connecting folded edges, even when the battery device is used in environments subject to vibration, shaking, or impact, such as vehicles, ships, or energy storage devices. This reduces the risk of wear on the outer sheath, insulation damage, leakage, short circuits, or arcing.

[0028] In some embodiments, the battery device includes: a wire harness locking clip, fixedly connected to the mounting boss, the wire harness locking clip being located outside the wiring port of the electrical connector, and the wire harness locking clip being used to clamp a portion of the wire harness near the wiring port.

[0029] The wire harness locking clip is fixed to the mounting boss and located outside the connector's terminal block, forming the first fixing point for the wire harness near the terminal block. Since the mounting boss itself supports the connector, the wire harness locking clip, once fixed to the mounting boss, maintains a high degree of positional consistency with the connector. The wire harness is clamped immediately or within a short distance after being led out of the terminal block, reducing the possibility of the wire harness swinging near the connector fold due to vibration. This further maintains the gap between the wire harness and the connector fold, improving the wire harness's anti-abrasion effect and the reliability of the electrical connection.

[0030] In some embodiments, the clamping surface of the wire harness locking clip is provided with an elastic pad.

[0031] The wire harness locking clip is used to hold the portion of the wire harness near the connection port. With an elastic pad on the clamping surface, the wire harness does not directly contact the rigid clamping surface of the clip. When the wire harness is subjected to vibration, shaking, impact, or external tension, the elastic pad absorbs some of the impact energy and disperses the clamping pressure, reducing the risk of the wire harness sheath being crushed, worn, or sheared. Therefore, the elastic pad further improves the protective effect of the wire harness locking clip on the wire harness and enhances the vibration resistance reliability of the wire harness near the connection port.

[0032] In some embodiments, the battery device further includes a protective plate fixedly attached to the outer surface of the housing assembly, the protective plate covering the side of the connection flange facing the wiring port of the electrical connector.

[0033] The gap between the mounting boss, the connector, and the connecting flange spatially reduces the probability of the wire harness coming into contact with the connecting flange, while the protective plate provides further physical protection on the side of the connecting flange facing the connector. In other words, the gap is for avoidance, and the protective plate is for protection. When the two work together, even if the wire harness undergoes significant displacement due to extreme vibration, external impact, or assembly errors, the protective plate can isolate the connecting flange, reducing the possibility of the wire harness making direct hard contact with the connecting flange, thereby improving abrasion resistance reliability.

[0034] In some embodiments, the battery device further includes a sleeve, one end of which is snapped into an electrical connector, and the other end of which is a free end extending in a direction away from the electrical connector. The sleeve is used to cover the wire harness connected to the electrical connector.

[0035] One end of the sleeve engages with the electrical connector, ensuring reliable positioning of the sleeve near the wire harness connector port. The other end of the sleeve extends away from the electrical connector and serves as a free end, providing continuous protection for the wire harness along its extension direction. In this way, after the wire harness exits from the connector port, both the portion near the port and the outward-extending portion are covered by the sleeve, reducing the possibility of direct friction between the wire harness and connecting flanges, the outer surface of the housing assembly, protective plates, mounting boss edges, or other adjacent structures.

[0036] Secondly, this application provides a battery assembly, including: a plurality of battery devices as described above, wherein the plurality of battery devices are arranged in a preset direction; wherein the wiring port of one of two adjacent battery devices is arranged facing the wiring port of the other, so that the wiring harness connecting the two adjacent battery devices extends in a straight line or an arc.

[0037] The battery assembly includes multiple battery devices arranged in a predetermined direction, with the wiring ports of one of two adjacent battery devices facing the wiring ports of the other, allowing the wiring harnesses between adjacent battery devices to be connected along a shorter and smoother path. Since the wiring ports of the aforementioned battery devices can be inclined relative to the side wall of the housing assembly, and the wiring harnesses can be protected using structures such as mounting bosses, gaps, wiring harness locking clips, sleeves, or protective plates, the wiring harnesses between adjacent battery devices in the battery assembly can be easily connected directly while reducing the risk of friction with connecting folds or the edges of the housing assembly.

[0038] In some embodiments, each battery device includes a positive connector and a negative connector arranged adjacent to each other, one end of a wiring harness is connected to the positive connector of one of the two adjacent battery devices, and the other end of the wiring harness is connected to the negative connector of the other of the two adjacent battery devices.

[0039] Thirdly, this application provides an energy storage device, which includes any of the above-mentioned battery devices or battery modules, wherein the battery devices are used to store electrical energy.

[0040] Energy storage devices include any of the aforementioned battery devices or battery modules, thus possessing the structural advantages of these battery devices or battery modules. For example, the external interface end of the electrical connector can be inclined relative to the side wall of the housing assembly to optimize the external wiring harness exit direction; a stable conductive path can be formed between the external and internal interface ends of the electrical connector by bending copper bars; the terminals of the positive and negative connectors can be parallel and form a gap with the connection fold; wiring harness locking clips, elastic gaskets, protective plates, and sleeves can collectively improve the wiring harness's abrasion resistance and vibration resistance reliability. Therefore, energy storage devices have higher electrical connection safety under long-term charging / discharging and vibration environments.

[0041] Fourthly, this application provides an electrical device that includes a battery device or battery assembly according to any of the above, wherein the battery device is used to provide electrical energy.

[0042] The electrical equipment includes any of the aforementioned battery devices or battery modules, thus possessing the structural advantages of such battery devices or battery modules. For example, the electrical connector can be mounted on the outside of the housing assembly via a mounting boss, creating a gap between the wiring port and the connecting flange; the wiring port can be angled relative to the side wall of the housing assembly to optimize the wire harness exit direction; wire harness locking clips, elastic gaskets, protective plates, and sleeves can collectively reduce the risk of wire harness wear; conductive connectors or copper bars can form a stable conductive path between the electrical connector and the internal electrical connectors of the housing assembly. Therefore, the electrical equipment can maintain high power supply reliability and safety under operating vibration, shock, or movement conditions.

Detailed Implementation

[0062] The embodiments of this utility model will now be described in detail. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0064] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0065] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0066] The following is combined with Figures 1-11 This invention describes battery devices, battery components, energy storage devices, and electrical appliances according to embodiments of the present invention.

[0067] The connection between the upper and lower housings of the battery pack forms an edge. The battery pack wiring will cross the edge. In some moving operating environments, such as ships, the wiring harness will sway with the movement of the electric vessel, causing the wiring to rub against the edge, which poses a safety hazard.

[0068] In related technologies, under continuous vibration environments such as ships, the connecting folds are relatively sharp, and the wire harness rubs repeatedly against the folds. Even with corrugated pipes, they are easily worn through, leading to leakage or short circuits in the internal core wires.

[0069] Based on the above considerations, in order to reduce the impact of the folded edge on the wiring harness, this application proposes a battery device that changes the connector to an outward protruding design, that is, the main body of the electrical connector protrudes from the plane of the side of the housing, so that the tail outlet naturally moves away from the folded edge of the housing, and the wiring harness moves away from the folded edge of the housing, thereby reducing the friction between the housing and the wiring harness.

[0070] like Figure 11 As shown, the battery device 100 disclosed in this application is mainly used in power battery systems for new energy vehicles, battery systems for energy storage power stations, etc. In the fields of electric vehicles or electric ships, the wiring harness will shake during operation, and the wiring harness will repeatedly rub against the folded edge. Even if there is a corrugated tube, it is easy to be worn through, resulting in leakage or short circuit of the internal core wires.

[0071] In some embodiments of this application, the battery device 100 can be used to supply power to the vehicle; for example, the battery device 100 can serve as the vehicle's operating power source. In other embodiments, the battery device 100 can not only serve as the vehicle's operating power source, but also as the vehicle's driving power source, replacing or partially replacing fuel or natural gas to provide driving power to the vehicle.

[0072] In this application, the battery device 100 mentioned in the embodiments refers to a single physical module comprising one or more battery cells to provide higher voltage and capacity. For example, the battery device 100 is composed of multiple battery cells connected in series or in parallel.

[0073] Combination Figure 1 As shown, in some embodiments of this application, a battery device 100 is proposed. The battery device 100 includes a housing assembly 102, a mounting boss 104, and an electrical connector 106.

[0074] The battery device 100 can be applied to energy storage systems, power equipment, marine power supply systems, vehicle power supply systems, engineering machinery power supply systems, or equipment requiring energy storage and output. Especially in environments with vibration, shaking, or impact, such as electric ships and vehicles, the wiring harness externally connected to the battery device 100 is prone to swaying with the movement of the equipment. This embodiment changes the positional relationship between the electrical connector 106 and the wiring harness relative to the side wall 103 and the connecting flange 1026 of the housing assembly 102, creating a gap between the wiring harness connected to the electrical connector 106 and the connecting flange 1026. This reduces contact and friction between the wiring harness and the connecting flange 1026, lowering the risk of insulation wear, damage, and resulting leakage, short circuits, or arcing.

[0075] The housing assembly 102 forms the external shell structure of the battery device 100 and houses components such as battery cells, modules, busbars, sampling harnesses, electrical connectors, insulators, and mounting brackets inside the battery device 100. The housing assembly 102 can be a metal housing assembly or a composite material housing assembly; for example, it can be made of aluminum alloy, steel plate, stainless steel, glass fiber reinforced composite material, or carbon fiber reinforced composite material. As the load-bearing foundation of the battery device 100, the housing assembly 102 provides mechanical protection for the internal electrical components and a fixed base for the mounting boss 104 and electrical connector 106. This allows the forces generated when the harness is subjected to vibration or tension to be transmitted to the housing assembly 102 through the electrical connector 106 and mounting boss 104, thereby improving the stability of the external electrical connection structure of the battery device 100.

[0076] The housing assembly 102 includes a bottom shell 1022 and a top cover 1024 connected to each other. The bottom shell 1022 can be a shell structure with a receiving cavity, and may include a bottom wall and side walls surrounding the bottom wall. The bottom shell 1022 is used to support battery cells, modules, or electrical components. The top cover 1024 is connected to the bottom shell 1022 and together with the bottom shell 1022, forms an installation space for accommodating internal battery components. The top cover 1024 can be a flat cover, a cover with reinforcing ribs, a stamped cover, a cast cover, or a profile welded cover. The bottom shell 1022 and the top cover 1024 can be connected by welding, screwing, riveting, snap-fitting, gluing, sealing press-fitting, or a combination of the foregoing methods. Through the interconnection of the bottom shell 1022 and the top cover 1024, the housing assembly 102 can form a relatively closed protective space, thereby improving the structural strength, sealing performance, and vibration resistance of the battery device 100.

[0077] A connecting flange 1026 is provided at the connection between the bottom shell 1022 and the top cover 1024, and the connecting flange 1026 is located on the side wall 103 of the housing assembly 102. The connecting flange 1026 can be a flange of the bottom shell 1022, a flange of the top cover 1024, an overlapping edge formed by the bottom shell 1022 and the top cover 1024 overlapping each other, a welded edge, a pressed edge, a flange edge, a reinforcing edge, or a sealing edge. The connecting flange 1026 can increase the connection area between the bottom shell 1022 and the top cover 1024, which is beneficial to improving the connection strength and sealing reliability of the two. For example, the upper end of the side wall of the bottom shell 1022 is bent outward to form a flange of the bottom shell 1022, and the edge of the top cover 1024 is attached to the flange of the bottom shell 1022 and fixed by welding or screwing, thereby forming the connecting flange 1026. For example, the edge of the top cover 1024 is folded down and covers the upper end of the side wall of the bottom shell 1022 to form a connecting flange 1026. Although the connecting flange 1026 can improve the connection reliability of the housing assembly 102, since the connecting flange 1026 is located on the side wall 103 of the housing assembly 102 and usually protrudes outward relative to the outer surface of the side wall 103 of the housing assembly 102, the connecting flange 1026 may become a friction point for the wiring harness when it swings. Especially when the battery device 100 is installed on a ship, vehicle or vibrating platform, the wiring harness may swing periodically relative to the housing assembly 102. If the wiring harness is close to the connecting flange 1026, the connecting flange 1026 may scratch the outer sheath of the wiring harness, causing wear to the wiring harness.

[0078] It needs to be emphasized that, such as Figure 2 As shown, the mounting boss 104 has a defined protrusion height H. The design standard for this height H is that it must be greater than the sheet metal flange formed at the junction of the upper and lower housings, i.e., the height h of the connecting flange, satisfying the relationship: H > h. Here, both H and h are measured along a direction perpendicular to the outer surface of the side wall 103.

[0079] It is understood that the mounting boss 104 has a protrusion height H along the direction perpendicular to the side wall 103 of the housing assembly 102, and the connecting flange 1026 has a protrusion height h relative to the outer surface of the side wall 103 in the same direction, where H is greater than h. Therefore, the terminal 1063 of the electrical connector 106 and the starting segment of the wire harness connected to the terminal 1063 can be moved outward in a direction away from the side wall 103, creating a gap between the wire harness and the connecting flange 1026. When the battery device 100 vibrates or shakes, the gap reduces the risk of contact and friction between the wire harness and the connecting flange 1026.

[0080] When the wiring harness (external cable) is connected to the fixed connector tail, the starting section of the harness is lifted to a higher spatial position by the electrical connector 106 and the mounting boss 104, that is, moved outwards along the direction away from the outer surface of the side wall 103 of the housing assembly 102. This naturally creates a safety gap between the wiring harness and the sharpest fold of the housing below. Regardless of the movement of the battery pack under conditions such as ship rolling, the swing trajectory of the wiring harness is restricted to the space above this gap, and it cannot physically contact the fold, thus eliminating the source of friction and wear.

[0081] Mounting boss 104 is fixedly connected to the outer surface of the side wall 103 of the enclosure assembly 102, and protrudes outward in a direction away from the interior of the enclosure assembly 102. Mounting boss 104 can be integrally formed with the enclosure assembly 102, or it can be fixed as a separate component to the outer surface of the side wall 103 of the enclosure assembly 102. For example, mounting boss 104 can be formed on the side wall 103 of the enclosure assembly 102 by stamping, casting, extrusion, machining, welding, riveting, screwing, gluing, or integral die casting. The material of mounting boss 104 can be the same as or different from the material of the enclosure assembly 102. For example, mounting boss 104 can be an aluminum alloy boss, a steel boss, a plastic boss, an insulating composite material boss, or a boss formed by a combination of metal inserts and insulating components. After the mounting boss 104 is fixedly connected to the outer surface of the side wall 103 of the housing assembly 102, it can serve as the mounting base for the electrical connector 106, so that the electrical connector 106 is no longer directly attached to the side wall 103 of the housing assembly 102, but is offset outward relative to the side wall 103 of the housing assembly 102. This changes the spatial position of the electrical connector 106 and the wire harness connected to the electrical connector 106, so that the initial lead-out position of the wire harness is far away from the connecting fold edge 1026.

[0082] The mounting boss 104 protrudes outwards in a direction away from the interior of the housing assembly 102, meaning that the mounting boss 104 extends from the outer surface of the side wall 103 of the housing assembly 102 towards the outside of the housing assembly 102. This protruding direction allows the mounting boss 104 to lift or move the electrical connector 106 outwards from the housing assembly 102, thereby moving the terminal 1063 of the electrical connector 106 away from the side wall 103 and the connecting flange 1026 of the housing assembly 102. The mounting boss 104 can be a columnar boss, a stepped boss, an annular boss, a frame-shaped boss, a block-shaped boss, a cylindrical boss, a beveled boss, or a boss with a mounting flange. The outer contour of the mounting boss 104 can be circular, elliptical, rectangular, polygonal, oblong, or irregularly shaped. Figure 2 As shown, the mounting boss 104 may have a first connecting portion 1042 for connecting the housing assembly 102, or a second connecting portion 1044 for connecting the electrical connector 106. The first connecting portion 1042 may be fitted to the side wall 103 of the housing assembly 102, and the second connecting portion 1044 may be located on the side of the first connecting portion 1042 away from the housing assembly 102 and be used to support the electrical connector 106. By forming an outwardly protruding mounting structure with the mounting boss 104, the wire harness does not need to be directly led out from a position close to the connecting fold 1026, but can be led out from a position further away from the housing assembly 102, structurally reducing the probability of the wire harness contacting the connecting fold 1026.

[0083] Electrical connector 106 is fixedly connected to mounting boss 104, and the terminal 1063 of electrical connector 106 is located on the side of mounting boss 104 away from housing assembly 102. Electrical connector 106 can be a high-voltage connector, low-voltage connector, signal connector, sampling connector, communication connector, charge / discharge connector, or multi-core composite connector. Electrical connector 106 may include connector housing, mating terminals, sealing ring, fixing flange, conductive terminals, locking element, or waterproof structure. Electrical connector 106 can be fixedly connected to mounting boss 104 by screws, bolts, clips, pressure plates, flanges, retaining rings, or sealing crimp structures. After electrical connector 106 is fixedly connected to mounting boss 104, the position of electrical connector 106 relative to mounting boss 104 remains stable, and the position of terminal 1063 is also fixed accordingly. After the wire harness is connected to electrical connector 106, the initial segment near terminal 1063 can be kept away from the connection fold 1026, reducing the possibility of the wire harness approaching the connection fold 1026 due to vibration, shaking, or pulling.

[0084] The connector 106's connection port 1063 is used to connect to the wire harness. The connection port 1063 can be a plug, terminal, cable outlet, tail outlet, female connector, male connector, or wire harness fixing port. The connection port 1063 is located on the side of the mounting boss 104 away from the housing assembly 102, meaning the connection port 1063 is closer to the outside of the housing assembly 102 relative to the mounting boss 104, rather than on the side of the mounting boss 104 closest to the housing assembly 102. Due to this positional relationship, when the wire harness exits from the connection port 1063, its starting position is located in the outer region of the mounting boss 104, thus away from the side wall 103 and the connecting flange 1026 of the housing assembly 102. This structure allows the wire harness exit position to be directly determined by the fixed installation position of the mounting boss 104 and the connector 106, without relying on manual binding or subsequent adjustments, thus improving the consistency of the wire harness's anti-abrasion effect in mass production.

[0085] Along the direction perpendicular to the side wall 103 of the housing assembly 102, the protrusion height of the mounting boss 104 relative to the outer surface of the side wall 103 is greater than the protrusion height of the connecting flange 1026 relative to the outer surface of the side wall 103. The direction perpendicular to the side wall 103 of the housing assembly 102 defines the height comparison direction of the mounting boss 104 and the connecting flange 1026, ensuring a unified measurement reference for their protrusion heights. The protrusion height of the mounting boss 104 relative to the outer surface of the side wall 103 can be understood as the distance by which the mounting boss 104 protrudes outward from the outer surface of the side wall 103 of the housing assembly 102; the protrusion height of the connecting flange 1026 relative to the outer surface of the side wall 103 can be understood as the distance by which the connecting flange 1026 protrudes outward from the outer surface of the side wall 103 of the housing assembly 102. By making the protrusion height of the mounting boss 104 relative to the outer surface of the side wall 103 greater than the protrusion height of the connecting flange 1026 relative to the outer surface of the side wall 103, the mounting boss 104 can extend beyond the outward protrusion range of the connecting flange 1026 in the outward direction, so that the electrical connector 106 fixedly connected to the mounting boss 104 and the wiring port 1063 located on the electrical connector 106 are further away from the side wall 103 of the housing assembly 102 relative to the connecting flange 1026.

[0086] The aforementioned height relationship allows a gap to be formed between the wire harness connected to the electrical connector 106 and the connecting flange 1026. This gap can be an air gap or a clearance space between the wire harness and the connecting flange 1026. The gap prevents the wire harness from contacting the connecting flange 1026 under normal installation conditions, or prevents the wire harness from easily rubbing against the connecting flange 1026 even under vibration, swaying, or slight tension. The gap can be located between the initial exit section of the wire harness and the connecting flange 1026, or between the bent section of the wire harness and the connecting flange 1026. The gap is defined by the protrusion height of the mounting boss 104, the installation position of the electrical connector 106, and the position of the connection port 1063, and does not entirely rely on additional protective components such as wire harness sheaths, cable ties, or tape, thus providing a more stable and reliable anti-abrasion effect.

[0087] In this embodiment, a clear anti-wear chain is formed between the mounting boss 104, the electrical connector 106, the wiring port 1063, the wire harness, and the connecting flange 1026. The housing assembly 102 is interconnected by the bottom shell 1022 and the top cover 1024 to form a stable housing structure. The connecting flange 1026 is provided at the connection between the bottom shell 1022 and the top cover 1024. The connecting flange 1026 improves the connection strength and sealing reliability of the housing assembly 102, and also constitutes a risk area for wire harness wear. The mounting boss 104 is fixedly connected to the outer surface of the side wall 103 of the housing assembly 102 and protrudes outward in a direction away from the interior of the housing assembly 102, so that the electrical connector 106 can be installed protruding outward. The electrical connector 106 is fixedly connected to the mounting boss 104, and the wiring port 1063 of the electrical connector 106 is located on the side of the mounting boss 104 away from the housing assembly 102, so that the wire harness lead-out position is away from the connecting flange 1026. Optionally, along the direction perpendicular to the side wall 103 of the housing assembly 102, the protrusion height of the mounting boss 104 relative to the outer surface of the side wall 103 is greater than the protrusion height of the connecting flange 1026 relative to the outer surface of the side wall 103, so that the wire harness is structurally located in the outer region of the connecting flange 1026, thereby forming a gap between the wire harness and the connecting flange 1026.

[0088] Compared to the structure where the electrical connector 106 is directly mounted on the side wall 103 of the housing assembly 102, this embodiment moves the electrical connector 106 and the terminal 1063 outward by using the mounting boss 104, so that the wiring harness does not need to be attached to the side wall 103 of the housing assembly 102 or lead out across the connecting flange 1026. When the wiring harness is subjected to vibration, shaking, or pulling, the gap can provide the wiring harness with swing space, reducing direct contact and repeated friction between the wiring harness and the connecting flange 1026. Therefore, this embodiment can reduce the risks of wear on the outer sheath of the wiring harness, damage to the insulation layer, exposure of conductors, leakage, short circuits, and arcing, thereby improving the safety, reliability, and service life of the battery device 100. At the same time, the above solution, by limiting the structure, creates a gap, reducing the reliance on manual binding, tape wrapping, or temporary sheaths, which is beneficial to improving the consistency and production efficiency of the batch assembly of the battery device 100.

[0089] In some embodiments, such as Figure 1 and Figure 3 As shown, the upper cover 1024 and the bottom shell 1022 are connected in the height direction. The height direction can be understood as the vertical direction of the housing assembly 102, or as the arrangement direction of the upper cover 1024 and the bottom shell 1022. Specifically, the bottom shell 1022 can be located below the housing assembly 102, and the upper cover 1024 can be located above the bottom shell 1022, covering or connecting to the bottom shell 1022 along the height direction. The upper cover 1024 and the bottom shell 1022 can be connected in the height direction by screwing, welding, riveting, snap-fitting, gluing, sealing and pressing, or a combination of the above methods, to jointly form a receiving space for accommodating battery cells, modules, electrical connectors, or electrical components. By defining the connection of the upper cover 1024 and the bottom shell 1022 in the height direction, the assembly direction of the housing assembly 102 and the formation position of the connecting flange 1026 can be clearly defined, so that the angular relationship between the opening direction of the wiring port 1063 in the electrical connector 106 and the height direction can be clearly defined by a spatial reference.

[0090] In some embodiments, the opening direction of the terminal 1063 in the electrical connector 106 is set at an angle θ with the height direction. The opening direction of the terminal 1063 can be understood as the direction in which the wire harness is inserted into the terminal 1063, the direction in which the wire harness is led out of the terminal 1063, the extension direction of the central axis of the terminal 1063, or the insertion direction when the electrical connector 106 and the wire harness are mated. The angle can be a non-zero angle, for example, the angle can be greater than 0° and less than 180°; optionally, the angle can be an acute angle or an obtuse angle, for example, 15°, 30°, 45°, 60°, 75°, 105°, 120° or 135°. By setting the opening direction of the terminal 1063 at an angle with the height direction, the wire harness can be led out at an angle relative to the height direction instead of directly upward or downward, thereby allowing the wire harness extension path to avoid the connection flange 1026, the edge of the side wall 103 of the housing assembly 102 or adjacent structural members.

[0091] After the top cover 1024 and the bottom shell 1022 are connected in the height direction, a connection area or connection flange 1026 distributed along the height direction is usually formed near the side wall 103 of the housing assembly 102. If the opening direction of the terminal 1063 in the electrical connector 106 is parallel to the height direction, the wire harness may extend along the connection area of ​​the top cover 1024 and the bottom shell 1022, increasing the probability that the wire harness will approach the connection flange 1026 or the edge of the side wall 103. In this embodiment, the opening direction of the terminal 1063 is set at an angle to the height direction, which can change the initial direction of the wire harness leading out from the electrical connector 106, so that the wire harness moves away from the connection flange 1026 or avoids the protruding structure on the side wall 103 of the housing assembly 102 in an inclined direction, thereby reducing the risk of friction between the wire harness and the connection flange 1026. In scenarios where multiple battery devices 100 are arranged horizontally or side-by-side, the inclined wiring method can also allow the wiring harness to extend toward the corresponding electrical connector 106 of the adjacent battery device 100, thereby reducing sharp bends in the wiring harness, reducing bending stress in the wiring harness, and shortening the length of the wiring harness.

[0092] In some specific examples, the opening direction of the connector 1063 can be tilted relative to the height direction towards the front, rear, left, or right side of the housing assembly 102. The connector 1063 can be a high-voltage connector, a low-voltage connector, a signal connector, a sampling connector, a communication connector, a charging connector, or a discharging connector. The electrical connector 106 can be a straight-through connector, an elbow connector, a tilted connector, a flange connector, or a connector with a tail outlet. By selecting different tilt directions and connector 1063 types, different battery device 100 arrangements and wiring harness routing paths can be accommodated. The angle between the opening direction of the connector 1063 and the height direction can be determined based on the minimum bending radius of the wiring harness, the spacing between adjacent battery devices 100, the dimensions of the side wall 103 of the housing assembly 102, the external dimensions of the electrical connector 106, and the position of the connecting flange 1026. When the wiring harness is a high-voltage harness or a large cross-sectional area harness, the included angle can be set to allow the harness to extend along a large radius arc or an approximately straight line, thereby reducing the difficulty of bending the harness and the stress of insertion. When the wiring harness is a low-voltage signal harness or a sampling harness, a smaller or larger included angle can be selected according to the harness diameter, routing space, and fixing point location, in order to improve the neatness and reliability of the wiring.

[0093] In some embodiments, such as Figure 1 and Figure 2 As shown, the bottom shell 1022 includes a connecting end face 1023 for connecting with the top cover 1024. The connecting end face 1023 can be disposed on the side wall end of the bottom shell 1022, or on the flange, folded edge, reinforcing edge, or sealing edge of the bottom shell 1022. The connecting end face 1023 is used for direct or indirect connection with the top cover 1024, so that the bottom shell 1022 and the top cover 1024 together form the housing assembly 102. The connecting end face 1023 can be a plane, a stepped surface, an annular surface, a frame-shaped surface, a partially spaced connecting surface, or a continuous connecting surface extending circumferentially along the bottom shell 1022. The top cover 1024 can be connected to the connecting end face 1023 by welding, screwing, riveting, snap-fitting, gluing, sealing press-fitting, or a combination of the foregoing methods. The connecting end face 1023 can provide an assembly reference for the connection between the upper cover 1024 and the bottom shell 1022, thereby improving the positioning accuracy, connection strength and sealing reliability of the upper cover 1024 and the bottom shell 1022.

[0094] The mounting boss 104 includes a first connecting portion 1042 for connecting to the side wall 103 of the housing assembly 102. The first connecting portion 1042 may be located on the side of the mounting boss 104 near the housing assembly 102 and fixedly connected to the outer surface of the side wall 103 of the housing assembly 102. The first connecting portion 1042 may be a base portion, root portion, flange portion, welded portion, mating portion, fixing plate portion, or annular connecting portion of the mounting boss 104. The first connecting portion 1042 may be connected to the side wall 103 of the housing assembly 102 by welding, screwing, riveting, snapping, gluing, integral molding, die casting, stamping, or machining. The first connecting portion 1042 is used to stably fix the mounting boss 104 to the housing assembly 102, enabling the mounting boss 104 to withstand the installation load of the electrical connector 106, the tensile load of the wire harness, and the dynamic load generated by the battery device 100 under vibration conditions, thereby improving the reliability of the external protruding mounting structure of the electrical connector 106.

[0095] The first connecting portion 1042 has a mounting surface for connecting or fitting with the outer surface of the side wall 103 of the housing assembly 102. The mounting surface of the first connecting portion 1042 can be a plane, slope, arc, step, annular, frame-shaped, or a non-circular surface that matches the shape of the side wall 103 of the housing assembly 102. The mounting surface of the first connecting portion 1042 can be fully fitted to the outer surface of the side wall 103 of the housing assembly 102, or it can be connected to the side wall 103 of the housing assembly 102 by partial fitting, circumferential fitting, spaced fitting, or sealing compression. The mounting surface of the first connecting portion 1042 can provide a stable force-bearing foundation for the mounting boss 104, allowing the external force on the electrical connector 106 to be transmitted to the housing assembly 102 via the mounting boss 104, thereby reducing local stress concentration at the root of the electrical connector 106 and the wire harness.

[0096] The mounting surface of the first connecting portion 1042 is inclined relative to the connecting end face 1023, and the included angle between the mounting surface of the first connecting portion 1042 and the connecting end face 1023 is an acute or obtuse angle. That is, the mounting surface of the first connecting portion 1042 is neither perpendicular to nor parallel to the connecting end face 1023, but rather forms a non-right-angle inclined relationship with respect to the connecting end face 1023. The included angle can be determined based on the shape of the side wall 103 of the housing assembly 102, the position of the connecting flange 1026, the protruding direction of the mounting boss 104, the opening direction of the wiring port 1063 of the electrical connector 106, and the wiring path of the wire harness. For example, the included angle between the mounting surface of the first connecting portion 1042 and the connecting end face 1023 can be 30°, 45°, 60°, 75°, 100°, 120°, 135°, or 150°.

[0097] By tilting the mounting surface of the first connecting portion 1042 relative to the connecting end face 1023, the mounting boss 104 can be offset relative to the connection point of the bottom shell 1022 and the top cover 1024. Since the connecting end face 1023 is usually close to the connection area of ​​the bottom shell 1022 and the top cover 1024, and the connecting flange 1026 is usually formed near the connection area, after the mounting surface of the first connecting portion 1042 is tilted relative to the connecting end face 1023, the mounting boss 104 can extend or be arranged in a direction away from the connecting flange 1026, so that the electrical connector 106 fixed on the mounting boss 104 and the wire harness connected to the electrical connector 106 are further away from the connecting flange 1026. As a result, when the wire harness is led out from the electrical connector 106, it is less likely to extend close to the connection end face 1023 or the connecting flange 1026, thereby reducing the risk of the wire harness contacting, scratching or repeatedly rubbing against the connecting flange 1026.

[0098] The connecting end face 1023 provides an assembly reference for the connection between the bottom shell 1022 and the top cover 1024. The first connecting portion 1042 provides a fixed base for the connection between the mounting boss 104 and the side wall 103 of the housing assembly 102. Since the mounting surface of the first connecting portion 1042 is inclined relative to the connecting end face 1023, the mounting boss 104 can be installed at an inclined position on the side wall 103 of the housing assembly 102. This inclined installation posture can change the positional relationship between the mounting boss 104, the electrical connector 106, and the wire harness relative to the connection area of ​​the bottom shell 1022 and the top cover 1024, making it easier for the wire harness's exit position and path to avoid the connecting fold 1026. Compared to a structure where the mounting surface of the first connecting portion 1042 is perpendicular to the connecting end face 1023, the above solution can adjust the posture of the mounting boss 104 according to the wire harness arrangement requirements, giving the wire harness more clearance and a smoother extension path.

[0099] Optionally, the sidewall of the bottom shell 1022 can be an inclined wall relative to the height direction. The connecting end face 1023 can be disposed at the upper end of the inclined wall and used to support the top cover 1024. The mounting surface of the first connecting part 1042 can fit against the outer surface of the inclined wall, so that the mounting surface of the first connecting part 1042 forms an acute angle or an obtuse angle with respect to the connecting end face 1023. In this case, the mounting boss 104 can conform to the shape of the inclined wall of the bottom shell 1022, reduce the assembly gap between the mounting boss 104 and the housing assembly 102, and improve the fixing stability of the mounting boss 104. Optionally, the sidewall of the bottom shell 1022 can include a stepped structure or a partial avoidance structure. The mounting surface of the first connecting part 1042 can be set as an inclined surface to avoid welds, sealing strips, bolt seats, or connecting flanges 1026 near the connecting end face 1023.

[0100] Optionally, the first connecting portion 1042 can be an annular flange portion, and the mounting surface of the first connecting portion 1042 is an annular bevel. The mounting boss 104 can be welded or sealed to the side wall 103 of the housing assembly 102 via the annular bevel. The annular bevel can form a continuous support and sealing structure around the mounting hole 108, improving the waterproof, dustproof, and vibration-resistant performance of the mounting area of ​​the electrical connector 106. Optionally, the first connecting portion 1042 can be a rectangular base portion, and the mounting surface of the first connecting portion 1042 is a rectangular bevel. The rectangular bevel can be fixed to the side wall 103 of the housing assembly 102 by bolts and sealed by a sealing gasket. This structure is easy to process and disassemble, and is suitable for battery devices 100 that require maintenance or replacement of the electrical connector 106.

[0101] In some embodiments, such as Figure 2 As shown, the mounting boss 104 includes a second connecting portion 1044 for connecting an electrical connector 106. The second connecting portion 1044 can be located on the side of the mounting boss 104 away from the housing assembly 102, or it can be located at the outer end, protruding end, stepped end, or flange end of the mounting boss 104. The second connecting portion 1044 provides a mounting base for the electrical connector 106, enabling the electrical connector 106 to be fixedly connected to the mounting boss 104 and keeping the connector's terminal 1063 on the side of the mounting boss 104 away from the housing assembly 102. The second connecting portion 1044 can be integrally formed with the first connecting portion 1042 of the mounting boss 104, or it can be separately formed from the first connecting portion 1042 and connected by welding, screwing, riveting, snap-fitting, gluing, or crimping. The second connecting portion 1044 can be a plate-shaped connecting portion, a flange connecting portion, an annular connecting portion, a frame-shaped connecting portion, a flange connecting portion, a seat connecting portion, or a connecting portion with a mounting hole 108.

[0102] The second connecting portion 1044 has a mounting surface for connecting with the electrical connector 106. The mounting surface of the second connecting portion 1044 can mate with the fixing flange, connector housing, sealing end face, mounting base, or connector base of the electrical connector 106. The electrical connector 106 can be fixed to the mounting surface of the second connecting portion 1044 by fasteners, snaps, pressure plates, locking elements, threaded connections, or sealing crimp structures. The mounting surface of the second connecting portion 1044 can be a plane, an annular plane, a rectangular plane, a stepped plane, a plane with a sealing groove, or a plane with a fastening hole. By providing the mounting surface of the second connecting portion 1044, a stable, defined, and machinable mounting reference can be provided for the electrical connector 106, ensuring that the position of the electrical connector 106 relative to the mounting boss 104 remains stable after assembly.

[0103] In some implementations, such as Figure 2As shown, plane A, where the mounting surface of the second connecting portion 1044 is located, is perpendicular to plane B, where the connecting end face 1023 is located. The connecting end face 1023 is the end face of the bottom shell 1022 used to connect with the top cover 1024, and is typically used to define the assembly position of the bottom shell 1022 and the top cover 1024. The mounting surface of the second connecting portion 1044 is the mounting reference surface for the connection between the electrical connector 106 and the mounting boss 104. By making the plane where the mounting surface of the second connecting portion 1044 is located perpendicular to the plane where the connecting end face 1023 is located, after the connection reference of the bottom shell 1022 and the top cover 1024 is determined, the mounting reference surface of the electrical connector 106 can form a clear perpendicular relationship with the connection reference, thereby improving the consistency and controllability of the mounting posture of the electrical connector 106. This structure facilitates the positioning and installation of the electrical connector 106 on the side wall 103 of the housing assembly 102, reduces assembly deviations caused by the uncertainty of the mounting surface tilt, makes the position of the wiring port 1063 of the electrical connector 106 more controllable, thereby facilitating the wire harness to be led out in a predetermined direction, and helps to maintain the gap between the wire harness and the connecting fold 1026.

[0104] The second connecting portion 1044 is used to reliably fix the electrical connector 106 to the mounting boss 104. Since the electrical connector 106 typically needs to withstand the insertion and extraction forces of the wire harness, the weight of the wire harness, the sway load of the wire harness, and external tensile loads, the second connecting portion 1044 needs to have sufficient connection strength and support rigidity. By supporting the electrical connector 106 through the second connecting portion 1044, the external force on the electrical connector 106 can be transmitted through the second connecting portion 1044 to the mounting boss 104, and then from the mounting boss 104 to the housing assembly 102, thereby reducing the risk of partial loosening of the electrical connector 106, misalignment of the connector port 1063, or concentrated force at the root of the wire harness. If a sealing groove, sealing gasket, sealing ring, or sealing adhesive layer is provided on the mounting surface of the second connecting portion 1044, the sealing performance between the electrical connector 106 and the mounting boss 104 can be improved, reducing the risk of moisture, dust, salt spray, or foreign matter entering the housing assembly 102 from the mounting area of ​​the electrical connector 106.

[0105] Optionally, the connecting end face 1023 can be a horizontal connecting surface at the upper end of the bottom shell 1022, and the mounting surface of the second connecting portion 1044 can be a vertical mounting surface extending laterally along the housing assembly 102. When the plane of the mounting surface of the second connecting portion 1044 is perpendicular to the plane of the connecting end face 1023, the electrical connector 106 can be mounted laterally on the second connecting portion 1044 along the housing assembly 102, and the wire harness can be led out laterally from the housing assembly 102. The above structure is suitable for scenarios where the electrical connector 106 is arranged on the side wall 103 of the housing assembly 102, which can keep the wire harness away from the connecting folded edge 1026 at the connection between the bottom shell 1022 and the top cover 1024, and facilitates the lateral side-by-side connection of multiple battery devices 100. Optionally, the second connecting portion 1044 can be provided with a connecting hole, a threaded hole, a positioning post, a positioning groove, a sealing groove, or a limiting step. The connecting hole or threaded hole can be used for fasteners such as screws and bolts to pass through, so as to fix the electrical connector 106 to the second connecting part 1044; the positioning post or positioning groove can be used to cooperate with the electrical connector 106 for positioning, to prevent the electrical connector 106 from being installed backwards or deflected; the sealing groove can be used to accommodate the sealing ring or sealing gasket, so as to improve the sealing reliability between the electrical connector 106 and the mounting boss 104; the limiting step can be used to limit the installation depth of the electrical connector 106, so that the wiring port 1063 of the electrical connector 106 is kept in a predetermined position.

[0106] Optionally, the second connecting portion 1044 can be connected to the first connecting portion 1042 via a transition portion. The transition portion can be an arc-shaped transition portion, a sloped transition portion, a reinforcing rib transition portion, a stepped transition portion, or a cylindrical transition portion. The first connecting portion 1042 is used to connect to the side wall 103 of the housing assembly 102, and the second connecting portion 1044 is used to connect to the electrical connector 106. The transition portion is used to transfer load between the first connecting portion 1042 and the second connecting portion 1044 and to improve the overall strength of the mounting boss 104. When the plane containing the mounting surface of the second connecting portion 1044 is perpendicular to the plane containing the connecting end face 1023, the transition portion can be adapted to the shape of the side wall 103 of the housing assembly 102 and the protrusion height of the mounting boss 104 to reduce local deformation of the mounting boss 104 under vibration or wire harness pulling conditions.

[0107] In some implementations, such as Figure 2As shown, the normal direction D of the mounting surface of the second connecting portion 1044 forms an angle with the normal direction C of the side wall 103 of the housing assembly 102. The normal direction of the mounting surface of the second connecting portion 1044 can be understood as a direction perpendicular to the mounting surface of the second connecting portion 1044, or as the direction referenced by the mounting axis, insertion axis, or opening direction of the terminal 1063 of the electrical connector 106 after it is installed on the second connecting portion 1044. The normal direction of the side wall 103 of the housing assembly 102 can be understood as a direction perpendicular to the side wall 103 of the housing assembly 102, or as a direction pointing from the inside of the housing assembly 102 to the outside of the housing assembly 102. The mounting surface of the second connecting part 1044 is set at an angle to the normal direction of the side wall 103 of the housing assembly 102. This means that the mounting surface of the second connecting part 1044 is not parallel to the outer surface of the side wall 103 of the housing assembly 102, but is arranged at an angle relative to the outer surface of the side wall 103 of the housing assembly 102, so that the electrical connector 106 can be installed on the mounting boss 104 in an inclined posture.

[0108] The second connecting portion 1044 not only supports and fixes the electrical connector 106, but also changes the mounting direction of the electrical connector 106 and the opening direction of the terminal 1063 by tilting the mounting surface. Since the normal direction of the mounting surface of the second connecting portion 1044 forms an angle with the normal direction of the side wall 103 of the housing assembly 102, after the electrical connector 106 is fixed to the second connecting portion 1044, the terminal 1063 of the electrical connector 106 can be tilted relative to the side wall 103 of the housing assembly 102 to face a predetermined direction. In this way, after the wire harness is connected to the terminal 1063, it can be led out along the tilted direction, without having to extend directly along a direction perpendicular to the side wall 103 of the housing assembly 102 and then make a sharp bend, thereby reducing wire harness bending, lowering internal stress in the wire harness, and improving the avoidance relationship between the wire harness and the connecting fold 1026. The included angle can be determined based on the wiring harness routing path, the arrangement position of adjacent battery devices 100, the position of the connecting flange 1026 on the side wall 103 of the housing assembly 102, and the size of the electrical connector 106. Through the included angle, the terminal 1063 can face away from the connecting flange 1026, towards the adjacent battery device 100, towards the wiring harness fixing point, or towards a predetermined wiring path.

[0109] Optionally, the angle between the normal direction of the mounting surface of the second connection portion 1044 and the normal direction of the side wall 103 of the housing assembly 102 can be an angle within the acute angle range, such as 5°, 10°, 15°, 30°, 45°, 60°, or 75°. When the angle is small, the electrical connector 106 is slightly inclined relative to the side wall 103 of the housing assembly 102, which is suitable for scenarios where the wire harness only needs to be slightly deflected to avoid the connection fold 1026 or enter the wiring channel. When the angle is large, the terminal 1063 of the electrical connector 106 can be clearly oriented to the side or at an angle, which is suitable for scenarios where multiple battery devices 100 are arranged side by side and the wire harness needs to extend towards the adjacent battery device 100.

[0110] Optionally, the side wall 103 of the housing assembly 102 can be a vertical side wall, with the normal direction of the side wall 103 being horizontal. The normal direction of the mounting surface of the second connecting part 1044 is inclined upward, downward, leftward, or rightward relative to the horizontal direction. Thus, the wiring port 1063 of the electrical connector 106 can be deflected towards the upper, lower, left, or right side of the housing assembly 102 to accommodate different wiring harness arrangement spaces. Optionally, the mounting surface of the second connecting part 1044 can be an inclined plane, with the fixing flange of the electrical connector 106 fitting against the inclined plane and fixed with bolts. The inclined plane allows the electrical connector 106 to be arranged at an overall angle, resulting in a simple structure that is easy to manufacture. The mounting surface of the second connecting part 1044 can also be a stepped inclined surface, a partial annular inclined surface, or a frame-shaped inclined surface to accommodate sealing grooves, positioning protrusions, reinforcing ribs, and electrical connectors 106 of different shapes.

[0111] Optionally, the second connecting portion 1044 may be provided with a positioning structure, which may be a positioning post, positioning hole, positioning groove, anti-rotation protrusion, limiting step, keyway, or foolproof structure. The positioning structure can prevent angular deviation during the assembly of the electrical connector 106, ensuring that the wiring port 1063 of the electrical connector 106 faces a predetermined direction, thereby improving the consistency of the wiring harness arrangement and reducing the possibility of the wiring harness approaching the connecting fold edge 1026 or undergoing unnecessary bending due to angular deviation of the electrical connector 106. A sealing structure may also be provided between the mounting surface of the second connecting portion 1044 and the electrical connector 106. The sealing structure may include a sealing ring, sealing gasket, sealing adhesive layer, elastic sealing lip, or potting layer. The sealing structure can fill the mating gap between the electrical connector 106 and the second connecting portion 1044, reducing the risk of moisture, dust, salt spray, or contaminants entering the housing assembly 102.

[0112] In some embodiments, such as Figure 4 and Figure 8As shown, the battery device 100 also includes a mounting hole 108, which is located on the side wall of the bottom shell 1022 and avoids the connecting flange 1026. A mounting boss 104 surrounds the outer periphery of the mounting hole 108, and at least a portion of the electrical connector 106 passes through the mounting hole 108. The mounting hole 108 is used to form a connection channel between the power connector 106 and the electrical components inside the housing assembly 102, enabling the electrical connector 106 to achieve electrical connection between the inner and outer sides of the housing assembly 102. The mounting hole 108 can be located in the middle, upper, lower part, or near the connection between the bottom shell 1022 and the top cover 1024, but spaced apart from the connecting flange 1026, on the side wall of the bottom shell 1022. The mounting hole 108 avoids the connecting flange 1026, meaning that the mounting hole 108 and the connecting flange 1026 are structurally spaced apart. The mounting hole 108 does not penetrate the connecting flange 1026, nor does it overlap with the connecting flange 1026, thereby reducing the weakening of the connection strength or sealing performance of the connecting flange 1026 due to the opening of the mounting hole 108.

[0113] The mounting hole 108 can be a round hole, an elliptical hole, an oblong hole, a rectangular hole, a polygonal hole, a stepped hole, a countersunk hole, or an irregularly shaped hole that matches the outer contour of the electrical connector 106. The edges of the mounting hole 108 can be chamfered, flanged, reinforced, sealed, or fitted with an insulating sleeve to improve the structural strength, sealing performance, and insulation safety of the mounting hole 108 edges. The mounting hole 108 can be formed by stamping, cutting, laser processing, machining, pre-casting, or profile opening. By providing the mounting hole 108 on the side wall of the bottom shell 1022, the inner portion of the electrical connector 106 can extend into the housing assembly 102 to connect with internal busbars, internal wiring harnesses, sampling boards, control boards, terminal blocks, or electrical connectors.

[0114] The mounting boss 104 surrounds the mounting hole 108, meaning that the mounting boss 104 at least partially surrounds the mounting hole 108 and is fixedly connected to the outer surface of the side wall of the bottom shell 1022. The mounting boss 104 can be continuously arranged around the mounting hole 108 or spaced apart around the mounting hole 108. For example, the mounting boss 104 can be an annular boss, a rectangular frame-shaped boss, a waist-shaped frame-shaped boss, a polygonal frame-shaped boss, a partially enclosing boss, or an enclosing boss with a notch. After the mounting boss 104 surrounds the mounting hole 108, it can strengthen the area around the mounting hole 108, increase the local rigidity of the side wall of the bottom shell 1022 around the mounting hole 108, and reduce the risk of deformation of the edge of the mounting hole 108 during the installation of the electrical connector 106 and the pulling of the wire harness.

[0115] At least a portion of the electrical connector 106 passes through the mounting hole 108. The electrical connector 106 may include an external portion located outside the housing assembly 102 and an internal portion extending into the housing assembly 102. The external portion may include a terminal block 1063, a plug end, an outer end of the connector housing, or a wire harness connection end; the internal portion may include an internal interface end 1064, a conductive terminal, a copper bar connection end, a pin, a socket, or an internal connection terminal. After at least a portion of the electrical connector 106 passes through the mounting hole 108, the electrical connector 106 can span across both sides of the side wall of the bottom shell 1022, allowing external wire harnesses to be electrically connected to electrical connectors inside the housing assembly 102 via the electrical connector 106. This through-hole relationship allows the electrical connector 106 to not only be an external interface fixed to the outside of the housing assembly 102, but also to form an electrical connection structure penetrating the side wall 103 of the housing assembly 102.

[0116] Mounting hole 108 provides a structural channel for electrical connector 106 to pass through the side wall of bottom housing 1022. Mounting hole 108 avoids connection flange 1026 to maintain structural strength and sealing performance at the connection between bottom housing 1022 and top cover 1024. Mounting boss 104 surrounds the periphery of mounting hole 108 to enhance the area around mounting hole 108 and provides an outward mounting base for electrical connector 106. At least a portion of electrical connector 106 passes through mounting hole 108, enabling electrical connection between internal electrical connectors and external wiring harnesses in housing assembly 102. Through the cooperation of these three elements, electrical connector 106 can be stably mounted on side wall 103 of housing assembly 102 while avoiding connection flange 1026, and the wiring harness connected to electrical connector 106 is kept away from connection flange 1026, thereby maintaining the gap between wiring harness and connection flange 1026.

[0117] Optionally, the mounting hole 108 can be located below and spaced apart from the connecting flange 1026. In this case, the mounting boss 104 surrounds the outer periphery of the mounting hole 108 and protrudes outward in a direction away from the interior of the housing assembly 102, so that the wiring port 1063 of the electrical connector 106 is located in the outer area of ​​the connecting flange 1026. After the wire harness is connected to the wiring port 1063, a gap can be formed between it and the connecting flange 1026 under the support and outward movement of the mounting boss 104. Optionally, the mounting hole 108 can be located to the side of the connecting flange 1026, with the mounting hole 108 and the connecting flange 1026 spaced apart in the horizontal or circumferential direction to avoid the connection area of ​​the bottom shell 1022 and the top cover 1024. This arrangement is suitable for housing structures where the connecting flange 1026 protrudes significantly or where fasteners, welds, or sealing strips are located near the connecting flange 1026.

[0118] Optionally, the mounting boss 104 may include a sealing mounting surface surrounding the mounting hole 108, to which the electrical connector 106 can be pressed against the sealing mounting surface by a sealing ring or a sealing gasket. The sealing ring may be an O-ring, a rectangular sealing ring, a rubber sealing gasket, a silicone sealing gasket, a foam sealing gasket, or a sealing layer formed by curing liquid sealant. The sealing mounting surface may be provided with a sealing groove, a limiting step, or a pressing flange to ensure that the periphery of the mounting hole 108 remains sealed after the electrical connector 106 passes through the mounting hole 108. The inner peripheral edge of the mounting hole 108 may be provided with an insulating sleeve, a flanged structure, or a chamfered structure. The insulating sleeve may be a rubber sleeve, a plastic sleeve, a nylon sleeve, an insulating ring, or an overmolded part, used to reduce direct contact between the conductive part of the electrical connector 106 or the internal wiring harness and the sidewall of the bottom shell 1022. The flanged structure may be formed by stamping to improve the edge strength of the mounting hole 108 and reduce sharp edges. The chamfered structure can reduce scratches caused by the edge of the mounting hole 108 to the shell, seals, or internal wiring harness of the electrical connector 106.

[0119] In some embodiments, such as Figure 7 As shown, the electrical connector 106 includes an external interface terminal 1062 and an internal interface terminal 1064. The external interface terminal 1062 is located on the outside of the housing assembly 102, and the internal interface terminal 1064 is located inside the housing assembly 102. The external interface terminal 1062 and the internal interface terminal 1064 can be electrically connected through conductive terminals, conductive connectors 1066, pins, sockets, copper bars 1068, aluminum bars, or cable connectors within the electrical connector 106. By arranging the external interface terminal 1062 and the internal interface terminal 1064 on the outside and inside of the housing assembly 102, respectively, the electrical connector 106 can form an internally and externally continuous electrical connection structure at the side wall 103 of the housing assembly 102, allowing external wiring harnesses to be connected to the battery device 100 through the external interface terminal 1062 and to the electrical connectors within the housing assembly 102 through the internal interface terminal 1064.

[0120] The external interface terminal 1062 can be a male interface, female interface, plug-in interface, wiring port, tail exit terminal, high-voltage interface, low-voltage interface, signal interface, sampling interface, communication interface, charging interface, or discharging interface. The external interface terminal 1062 may include the outer end of the connector housing, plug-in cavity, terminal hole, locking structure, sealing ring, guide structure, foolproof structure, or wire harness fixing structure. With the external interface terminal 1062 located outside the enclosure assembly 102, the external wire harness can be plugged in, locked, and maintained outside the enclosure assembly 102 without opening the enclosure assembly 102, thus improving assembly and maintenance convenience.

[0121] The external interface terminal 1062 is inclined relative to the side wall 103 of the housing assembly 102. Inclined can be understood as the insertion direction, opening direction, central axis direction, or wire harness lead-out direction of the external interface terminal 1062 forming an angle with respect to the outer surface of the side wall 103 of the housing assembly 102 or with respect to the normal direction of the side wall 103 of the housing assembly 102. This angle can be determined based on the wire harness routing path, the position of adjacent battery devices 100, the position of the connecting fold 1026, and the minimum bending radius of the wire harness. For example, the external interface terminal 1062 can be inclined upwards, downwards, to the left, to the right, or towards adjacent battery devices 100 relative to the side wall 103 of the housing assembly 102. By tilting the external interface terminal 1062 relative to the side wall 103 of the housing assembly 102, the wire harness connected to the external interface terminal 1062 can be led out in the tilt direction, reducing the occurrence of sharp bends immediately after the wire harness is led out from the electrical connector 106, and reducing the risk of the wire harness approaching the connection fold 1026.

[0122] The internal interface terminal 1064 can be an internal plug-in terminal, an internal terminal terminal, a copper bus connection terminal, a busbar connection terminal, a sampling board connection terminal, a screw terminal, a solder terminal, a crimp terminal, or a pin terminal. The internal interface terminal 1064 can connect to electrical connectors within the housing assembly 102. These electrical connectors can be busbars, copper busbars, aluminum busbars, sampling boards, control boards, relay connection terminals, fuse connection terminals, internal wiring harness terminals, terminal blocks, or battery management system connection terminals. Located inside the housing assembly 102, the internal interface terminal 1064 shortens the connection path between the electrical connector 106 and the internal electrical connectors, reduces internal wiring length and connection nodes, and improves the stability of internal electrical connections.

[0123] like Figure 7 As shown, the internal interface terminal 1064 has an internal connection surface E. The internal connection surface can be a connection reference surface for mating, contacting, welding, screwing, crimping, or plugging with electrical connectors. The internal connection surface can be a plane, end face, stepped surface, lap surface, welding surface, crimping surface, terminal contact surface, or bolt locking surface. The internal connection surface can be provided with connection holes, threaded holes, positioning holes, positioning posts, welding areas, plating, conductive contact areas, or insulating isolation structures. By providing an internal connection surface, the internal interface terminal 1064 can form a stable mechanical and electrical connection with electrical connectors, reducing the risk of poor contact, intermittent connections, overheating, or loosening.

[0124] like Figure 7As shown, the internal connection surface E is arranged parallel to the connection surface F of the electrical connector located within the housing assembly 102. The connection surface of the electrical connector can be a busbar connection surface, copper busbar connection surface, sampling board terminal surface, terminal block connection surface, control board connection surface, internal wiring harness terminal surface, or bolt fastening surface. With the internal connection surface and the connection surface of the electrical connector arranged parallel, they can be connected by face-to-face contact, face-to-face mating, parallel overlap, or parallel insertion. This structure reduces the angular deviation between the internal interface end 1064 and the electrical connector, eliminating the need for additional bending, twisting, or forced correction during connection, thereby reducing assembly difficulty and improving connection reliability.

[0125] The external interface end 1062 is inclined relative to the side wall 103 of the housing assembly 102, which optimizes the wire harness exit direction on the outside of the housing assembly 102, making it easier for the wire harness to avoid the connection fold 1026 and extend along a predetermined path. The internal interface end 1064 is located inside the housing assembly 102 and has an internal connection surface. The internal connection surface is parallel to the connection surface of the electrical connector located inside the housing assembly 102, which optimizes the electrical connection direction inside the housing assembly 102, enabling a straight and stable connection between the internal interface end 1064 and the electrical connector. Thus, the electrical connector 106 can simultaneously meet the requirements of external inclined wire exit and internal straight wire exit, improving the anti-wear effect of the wire harness while reducing the assembly difficulty of the electrical connector inside the housing assembly 102.

[0126] Optionally, the external interface end 1062 can be inclined relative to the side wall 103 of the housing assembly 102 towards the adjacent battery device 100. After the external wiring harness is connected to the external interface end 1062, it can extend in an approximately straight direction to the corresponding connector of the adjacent battery device 100. The above structure is suitable for scenarios where multiple battery devices 100 are arranged side by side, which can reduce the bending of the wiring harness between adjacent battery devices 100, reduce the wiring harness length and assembly difficulty. Optionally, the external interface end 1062 can be inclined relative to the side wall 103 of the housing assembly 102 away from the connecting fold edge 1026, so that the starting section of the external wiring harness is further away from the connecting fold edge 1026, thereby enhancing the anti-wear effect. The internal connection surface of the internal interface end 1064 can be a horizontal connection surface or a vertical connection surface, and is arranged parallel to the corresponding connection surface of the electrical connector. The two can be connected by bolting, welding, crimping, plugging or screwing. The internal connection surface can also be provided with an anti-rotation positioning structure and a conductive plating layer. The anti-rotation positioning structure can be a positioning post, positioning hole, limiting groove, stop edge, step part or anti-fooling protrusion; the conductive plating layer can be a tin plating layer, a nickel plating layer, a silver plating layer or a composite plating layer.

[0127] In some embodiments, such as Figure 7As shown, the battery device 100 also includes a conductive connector 1066. The conductive connector 1066 forms a conductive path within or near the electrical connector 106, enabling an electrical connection between the external interface end 1062 and the internal interface end 1064. The conductive connector 1066 can be a copper bar 1068, an aluminum bar, a conductive busbar, a conductive sheet, a conductive terminal, a pin, a spring, a flexible conductive element, a braided copper strip, a flexible busbar, or a composite conductive element. The conductive connector 1066 can be selected based on the voltage level, current magnitude, heat dissipation requirements, installation space, and connector structure of the battery device 100. By providing the conductive connector 1066, the electrical connector 106 can form a stable, low-impedance electrical connection path between the external interface end 1062 and the internal interface end 1064, thereby improving the reliability of current or signal transmission between the external wiring harness and the internal electrical connections of the housing assembly 102.

[0128] At least a portion of the conductive connector 1066 is disposed within the electrical connector 106. The conductive connector 1066 may be entirely disposed within the electrical connector 106, or partially disposed within the electrical connector 106 with another portion extending beyond the electrical connector 106 and reaching the vicinity of the housing assembly 102 or the external interface end 1062. The electrical connector 106 may include a connector housing, an insulating support, a seal, a terminal fixing member, or a shielding structure. The conductive connector 1066 may be positioned and fixed by the connector housing and the insulating support. By disposing at least a portion of the conductive connector 1066 within the electrical connector 106, the electrical connector 106 can provide mechanical protection, insulation isolation, positional limitation, and sealing protection for the conductive connector 1066, reducing the risks of contact, short circuits, contamination, or corrosion caused by exposed conductive connector 1066.

[0129] One end of the conductive connector 1066 is electrically connected to the external interface terminal 1062, and the other end is electrically connected to the internal interface terminal 1064. One end of the conductive connector 1066 can be electrically connected to the pins, sockets, terminals, contacts, crimp ends, solder ends, or wire harness connection ends of the external interface terminal 1062; the other end of the conductive connector 1066 can be electrically connected to the connection surface, terminal block, copper busbar connection end, busbar connection end, screw end, solder end, plug end, or crimp end of the internal interface terminal 1064. The electrical connection method can be integral molding, welding, riveting, crimping, screwing, plugging, brazing, ultrasonic welding, lap splicing, or conductive elastic contact. By connecting the conductive connector 1066 to the external interface terminal 1062 and the internal interface terminal 1064, the current or signal in the external wire harness can be transmitted to the conductive connector 1066 and further to the electrical connectors inside the housing assembly 102, reducing intermediate connection nodes and improving electrical connection stability.

[0130] The conductive connector 1066 is bent between the external interface end 1062 and the internal interface end 1064. The bending of the conductive connector 1066 can be a single bend, multiple bends, right-angle bends, obtuse-angle bends, acute-angle bends, arc bends, stepped bends, Z-shaped bends, L-shaped bends, U-shaped bends, or three-dimensional spatial bends. The angle and shape of the bending of the conductive connector 1066 can be determined based on the tilt direction of the external interface end 1062, the connection direction of the internal interface end 1064, the internal space of the electrical connector 106, and the position of the electrical connectors inside the housing assembly 102. By bending the conductive connector 1066 between the external interface end 1062 and the internal interface end 1064, even when the external interface end 1062 is tilted relative to the side wall 103 of the housing assembly 102, the direction of current or signal transmission can be converted to a direction suitable for the connection between the internal interface end 1064 and the electrical connector.

[0131] The conductive connector 1066 can form an electrical connection path with direction-reversing capability between the external interface end 1062 and the internal interface end 1064. Since the external interface end 1062 can be inclined relative to the side wall 103 of the enclosure assembly 102, allowing the external wiring harness to exit at an angle and avoid the connection fold 1026; and the internal connection surface of the internal interface end 1064 can be parallel to the connection surface of the electrical connectors within the enclosure assembly 102, allowing for a straight internal connection, the directions of the external interface end 1062 and the internal interface end 1064 may not be consistent. By bending the conductive connector 1066 between the external interface end 1062 and the internal interface end 1064, the inclined external interface and the straight internal interface can be effectively connected, thereby simultaneously satisfying the requirements of convenient external wiring harness arrangement and reliable internal electrical connection.

[0132] Optionally, the conductive connector 1066 can be an L-shaped bend, with one end extending along the insertion direction of the external interface end 1062 and the other end extending along the connection direction of the internal interface end 1064. This is suitable for scenarios where the external interface end 1062 and the internal interface end 1064 form an approximately right-angle transition. Optionally, the conductive connector 1066 can be a Z-shaped bend. The Z-shaped bend can provide a certain height difference or positional offset while achieving a direction transition, making it suitable for scenarios where the external interface end 1062 and the internal interface end 1064 are not at the same height or on the same straight line. Optionally, the conductive connector 1066 can be an arc-shaped bend. The arc-shaped bend can reduce stress concentration at the bend, making it suitable for scenarios where it is necessary to improve the vibration fatigue resistance of the conductive connector 1066.

[0133] Optionally, the conductive connector 1066 may be provided with an insulating coating, an insulating support, an isolation structure, a positioning structure, or a buffer structure. The insulating coating may be a heat-shrink tubing, an insulating coating, a plastic coating, an epoxy encapsulation, or a silicone coating. The insulating support may be an insulating seat, an insulating partition, an insulating sleeve, an insulating clip, or an insulating bracket. The positioning structure may be a positioning hole, a positioning groove, a limiting protrusion, a snap-fit ​​portion, a stop portion, or a screw hole. The buffer structure may be an elastic bending section, a flexible braided section, a wave-shaped section, or an arc-shaped transition section. The insulating coating or insulating support ensures electrical isolation between the conductive connector 1066 and the housing, enclosure assembly 102, or adjacent conductive components of the electrical connector 106, reducing the risk of short circuits. The positioning structure prevents the conductive connector 1066 from shifting during long-term vibration. The buffer structure reduces the risk of fatigue damage at the bending points of the conductive connector 1066.

[0134] In some embodiments, such as Figure 7 and Figure 8 As shown, the conductive connector 1066 is a copper bar 1068. The copper bar 1068 can be a conductive busbar, conductive sheet, conductive plate, conductive terminal, or bus connector made of copper or copper alloy materials. The copper bar 1068 can be made of pure copper, oxygen-free copper, tin-plated copper, nickel-plated copper, silver-plated copper, or copper alloy materials. The copper bar 1068 can be formed into a predetermined shape through processes such as stamping, cutting, bending, machining, welding, riveting, pressing, or surface electroplating. Because the copper bar 1068 has high conductivity, low connection resistance, and good mechanical strength, it is suitable for electrical connection structures in high-voltage, high-current, or long-term vibration environments in the battery device 100. By setting the conductive connector 1066 as a copper bar 1068, the conductivity between the external interface terminal 1062 and the internal electrical connector can be improved, the risk of heat generation during current transmission can be reduced, and the structural stability of the internal conductive path of the electrical connector 106 can be improved.

[0135] One end of the copper bar 1068 is located inside the electrical connector 106, and this end is connected to the external interface terminal 1062. This end of the copper bar 1068 can serve as an external connection terminal, plug-in terminal, terminal connection terminal, crimp terminal, solder terminal, riveting terminal, or screw terminal, connecting to the conductive terminals, pins, sockets, contacts, connecting terminals, or wire harness plug-in terminals of the external interface terminal 1062. With one end of the copper bar 106 inside the electrical connector 106, it is protected by the connector 106's housing, insulating support, and sealing structure, reducing the risk of accidental contact, short circuits, contamination, or corrosion caused by the exposed copper bar 1068. Simultaneously, it allows the external wire harness, when plugged into the external interface terminal 1062, to transmit current or signals to the copper bar 1068 through the external interface terminal 1062.

[0136] The other end of the copper bar 1068 is located inside the housing assembly 102 and is connected to the electrical connector. The other end of the copper bar 1068 can serve as an internal connection terminal, busbar connection terminal, screw terminal, solder terminal, lap terminal, crimp terminal, or plug terminal, connecting to the electrical connector located within the housing assembly 102. The electrical connector can be a busbar, copper busbar, aluminum busbar, battery cell terminal connector, module output terminal, relay connection terminal, fuse connection terminal, sampling board connection terminal, terminal block, or internal wiring harness terminal. The fact that the other end of the copper bar 1068 is located inside the housing assembly 102 shortens the conductive path between the electrical connector 106 and the internal electrical connector of the housing assembly 102, reducing the number of intermediate adapters and thus lowering connection resistance and the number of potential failure points.

[0137] One end of the copper bar 1068 is located inside the electrical connector 106 and connected to the external interface terminal 1062. The other end of the copper bar 1068 is located inside the housing assembly 102 and connected to the electrical connector. This allows the copper bar 1068 to bridge the electrical connector 106 and the electrical connector inside the housing assembly 102, forming a stable, low-impedance, and structurally strong electrical connection path between the external interface terminal 1062 and the electrical connector. After the external wiring harness is connected to the external interface terminal 1062, current or signals can be transmitted sequentially through the external interface terminal 1062, the copper bar 1068, and the electrical connector to the electrical system inside the housing assembly 102. This structure reduces the risks of vibration, fatigue, and poor contact caused by the flexible cable transition inside the electrical connector 106, while improving high-current transmission capacity and vibration resistance reliability.

[0138] Optionally, the copper bar 1068 can be a one-piece bent copper bar, with one end located inside the electrical connector 106 and connected to the external interface terminal 1062, and the other end extending into the housing assembly 102 and connected to the electrical connector. Specifically, the copper bar 1068 can be formed by stamping and bending a single copper plate, resulting in fewer connection nodes, lower resistance, and higher structural strength. Optionally, the copper bar 1068 can be a split-connection copper bar, with one end connected to the conductive terminal of the external interface terminal 1062, and the other end connected to the busbar inside the housing assembly 102 via bolts. The split-connection structure allows for adjustment of the shape of the copper bar 1068 according to different electrical connector 106 specifications, housing dimensions, or the position of internal electrical connectors, improving product adaptability.

[0139] Optionally, the copper bar 1068 may have a straight section, a bent section, and a connecting section. The straight section can be used to pass through or be positioned within the electrical connector 106, the bent section can be used to achieve directional conversion between the external interface end 1062 and the internal electrical connector, and the connecting section can be used to overlap, lock, or solder with the electrical connector. The bent section can be an L-shaped bend, a Z-shaped bend, a U-shaped bend, a stepped bend, or an arc bend. One end of the copper bar 1068 may be provided with a plug-in terminal structure, which mates with the plug-in structure of the external interface end 1062; the other end of the copper bar 1068 may be provided with a through hole, a threaded hole, an oblong hole, a soldering area, a crimping area, an overlapping surface, or a plated contact surface for fixed connection with the electrical connector. The outer surface of the copper bar 1068 may be provided with an insulating layer or a protective layer. The insulating layer can be a heat shrink tubing, an insulating coating, an epoxy coating, a plastic coating, a silicone coating, or an insulating sleeve. The protective layer can be a tin-plated layer, a nickel-plated layer, a silver-plated layer, an anti-oxidation coating, or an anti-corrosion coating. The copper bar 1068 can also be fixed inside the electrical connector 106 by an insulating support, which can be an insulating base, a terminal base, a limit block, a snap-fit ​​base, a potting compound, or an insulating partition.

[0140] In some embodiments, such as Figure 3 As shown, the electrical connector 106 includes a positive connector 1072 and a negative connector 1074 arranged adjacent to each other. The positive connector 1072 is used to form a positive electrical connection path for the battery device 100, and the negative connector 1074 is used to form a negative electrical connection path for the battery device 100. The positive connector 1072 and the negative connector 1074 can both be disposed on the outer side of the side wall 103 of the housing assembly 102 and both fixedly connected to the mounting boss 104; or they can be fixedly connected to two adjacent mounting bosses 104 respectively. The positive connector 1072 and the negative connector 1074 being arranged adjacent to each other means that the positive connector 1072 and the negative connector 1074 are arranged close to each other in the same side wall area of ​​the housing assembly 102, and they can be arranged at intervals along the length direction, width direction, height direction of the housing assembly 102, or circumferential direction of the side wall 103. By arranging the positive connector 1072 and the negative connector 1074 adjacent to each other, the positive and negative interfaces of the battery device 100 can be arranged in a centralized manner, which facilitates unified insertion, routing and maintenance of external wiring harnesses.

[0141] The positive connector 1072 can be a positive high-voltage connector, a positive charge / discharge connector, a positive power connector, a positive plug terminal, or a positive wire harness interface. The negative connector 1074 can be a negative high-voltage connector, a negative charge / discharge connector, a negative power connector, a negative plug terminal, or a negative wire harness interface. The positive connector 1072 and the negative connector 1074 can have the same dimensions or different dimensions; they can use the same mounting method or different mounting methods. For example, both the positive connector 1072 and the negative connector 1074 can be fixed to the mounting boss 104 using bolts, screws, clips, pressure plates, flanges, retaining rings, or locking devices. The positive connector 1072 and the negative connector 1074 can also be equipped with foolproof structures, color markings, polarity markings, locking structures, or coding structures to prevent incorrect positive and negative insertion.

[0142] The opening direction of the connector port of positive connector 1072 is parallel to the opening direction of the connector port of negative connector 1074. The opening direction of the connector port of positive connector 1072 can be understood as the direction in which the positive wire harness is inserted into positive connector 1072, the direction in which the positive wire harness is led out of positive connector 1072, or the extension direction of the central axis of the connector port of positive connector 1072. The opening direction of the connector port of negative connector 1074 can be understood as the direction in which the negative wire harness is inserted into negative connector 1074, the direction in which the negative wire harness is led out of negative connector 1074, or the extension direction of the central axis of the connector port of negative connector 1074. The parallelism of the opening directions of the connector ports of positive connector 1072 and negative connector 1074 means that the positive and negative wire harnesses can be connected or led out in the same or substantially the same direction, so that the positive and negative wire harnesses form a consistent routing direction on the outside of electrical connector 106.

[0143] The adjacent arrangement of the positive connector 1072 and negative connector 1074 concentrates the external interfaces of the positive and negative terminals of the battery device 100, reducing the space occupation and assembly complexity caused by the dispersed arrangement of the positive and negative wire harnesses on the outside of the housing assembly 102. The opening direction of the wiring port of the positive connector 1072 is parallel to the opening direction of the wiring port of the negative connector 1074, allowing the positive and negative wire harnesses to be led out of the battery device 100 in a parallel or nearly parallel manner. As a result, the positive and negative wire harnesses can extend along the same wiring channel, which facilitates bundling, fixing, sheathing, and path planning, and reduces wire harness crossings, twists, sharp bends, or mutual interference.

[0144] The positive connector 1072 provides a positive external connection terminal for the battery device 100. After the external positive wiring harness is connected to the positive connector 1072, it can be electrically connected to the positive electrical connector inside the housing assembly 102. The positive electrical connector can be a positive busbar, a positive copper busbar, a positive output terminal, a positive relay connection terminal, a positive fuse connection terminal, or a positive module connection terminal. The negative connector 1074 provides a negative external connection terminal for the battery device 100. After the external negative wiring harness is connected to the negative connector 1074, it can be electrically connected to the negative electrical connector inside the housing assembly 102. The negative electrical connector can be a negative busbar, a negative copper busbar, a negative output terminal, a negative relay connection terminal, a negative fuse connection terminal, or a negative module connection terminal. Through the positive connector 1072 and the negative connector 1074, the battery device 100 can be connected to the positive and negative terminals of an external charging and discharging device, an adjacent battery device 100, an energy storage system bus, or an electrical device 400.

[0145] Optionally, the positive connector 1072 and the negative connector 1074 can be arranged adjacent to each other along the length of the housing assembly 102, and the opening direction of the wiring port of the positive connector 1072 and the opening direction of the wiring port of the negative connector 1074 both face the same side of the housing assembly 102. This structure is suitable for scenarios where multiple battery devices 100 are arranged side-by-side along the length or width direction, allowing the positive and negative wire harnesses to be led out parallel to adjacent battery devices 100 or external busbars. Optionally, the positive connector 1072 and the negative connector 1074 can be arranged adjacent to each other along the height direction, and the opening directions of their wiring ports are parallel, so that the positive and negative wire harnesses are spaced apart in the vertical direction and extend in the same direction, thereby facilitating layered wiring and insulation spacing control. The opening direction of the connector port of the positive connector 1072 and the opening direction of the connector port of the negative connector 1074 can both be inclined relative to the side wall 103 of the housing assembly 102, and the inclination direction of the two is the same, so as to reduce the sharp bends of the two wire harnesses at the connector ports and to keep the two wire harnesses away from the connection fold 1026 at the same time. An insulating isolation structure can also be provided between the positive connector 1072 and the negative connector 1074. The insulating isolation structure can be an insulating partition, insulating rib, insulating spacer, insulating cover, insulating sleeve or air gap, to maintain the electrical safety distance between the positive and negative poles and reduce the risk of short circuit or creepage.

[0146] In some embodiments, a gap is formed between the terminal of the positive connector 1072 and the connecting flange 1026 in a direction perpendicular to the side wall 103 of the housing assembly 102, and a gap is also formed between the terminal of the negative connector 1074 and the connecting flange 1026. The direction perpendicular to the side wall 103 of the housing assembly 102 can be understood as the outward convex direction of the side wall 103 of the housing assembly 102 from the inside out, or as the local normal direction of the side wall 103 of the housing assembly 102. The gaps formed between the terminal of the positive connector 1072 and the terminal of the negative connector 1074 and the connecting flange 1026 respectively mean that, in the outward convex direction, there is a space between the terminal of the positive connector 1072 and the connecting flange 1026, and between the terminal of the negative connector 1074 and the connecting flange 1026, so that the positive wire harness connected to the positive connector 1072 and the negative wire harness connected to the negative connector 1074 can respectively avoid the connecting flange 1026.

[0147] The positive connector 1072 can have a positive terminal, a positive terminal outlet, a positive wire harness outlet, a positive high-voltage outlet, a positive charge / discharge outlet, or a positive power outlet. The negative connector 1074 can have a negative terminal, a negative terminal, a negative wire harness outlet, a negative high-voltage outlet, a negative charge / discharge outlet, or a negative power outlet. The terminals of the positive connector 1072 and the negative connector 1074 can be located on the side of the mounting boss 104 away from the housing assembly 102, or they can be located on the side of two adjacent mounting bosses 104 away from the housing assembly 102. By creating a gap between both terminals and the connecting flange 1026, both the positive and negative wire harnesses can be protected against abrasion, preventing only one side of the wire harness from being effectively avoided while the other side remains close to the connecting flange 1026.

[0148] The gap can be an air gap, clearance space, buffer space, harness swing space, or isolation gap. The gap can be formed between the connector port of the positive connector 1072 and the connecting flange 1026, or between the connector port of the negative connector 1074 and the connecting flange 1026; more specifically, the gap can be formed on the outer periphery of the connector port, at the harness connection end, in the area near the central axis of the connector port, or between the starting segment of the harness connected to the connector port and the connecting flange 1026. The gap size can be determined based on the harness outer diameter, the minimum bending radius of the harness, the protrusion height of the connecting flange 1026, the protrusion height of the mounting boss 104, the equipment vibration amplitude, and assembly tolerances. For example, the gap can be a space of several millimeters to tens of millimeters to meet the clearance requirements of the harness under vibration and swing conditions.

[0149] The positive connector 1072 and negative connector 1074 serve as the positive and negative external interfaces of the battery device 100, respectively, and typically require connection to the positive and negative wiring harnesses. By creating gaps between the terminals of the positive connector 1072 and the negative connector 1074 and the connecting fold 1026 along a direction perpendicular to the side wall 103 of the housing assembly 102, the initial exit areas of both the positive and negative wiring harnesses are kept away from the connecting fold 1026. This ensures that even if the battery device 100 is used in environments subject to vibration, shaking, or impact, such as vehicles, ships, or energy storage devices, the positive and negative wiring harnesses are less likely to come into contact with, scratch, or repeatedly rub against the connecting fold 1026, thereby reducing the risk of wear on the outer sheath, insulation damage, leakage, short circuits, or arcing.

[0150] Optionally, the positive connector 1072 and the negative connector 1074 can both be fixed to the same mounting boss 104. The mounting boss 104 protrudes outward relative to the outer surface of the side wall 103 of the housing assembly 102, so that the wiring ports of the positive connector 1072 and the negative connector 1074 are both located in the outer area of ​​the connecting flange 1026. In this case, gaps are formed between the two wiring ports and the connecting flange 1026, and the positive and negative wire harnesses can be led out from the two wiring ports in a parallel direction, both avoiding the connecting flange 1026. Optionally, the positive connector 1072 and the negative connector 1074 can be fixed to two adjacent mounting bosses 104 respectively. The protrusion height of the two mounting bosses 104 is greater than the protrusion height of the connecting flange 1026 relative to the outer surface of the side wall 103 of the housing assembly 102, so as to provide gaps for the two wiring ports respectively. The gap can be formed continuously along the arrangement direction of the terminals of the positive connector 1072 and the negative connector 1074, or it can be formed locally at corresponding positions of the two terminals. The continuous gap allows the positive and negative wire harnesses to avoid the connection fold 1026 as a whole when they are running in parallel, while the local gaps can meet the anti-wear requirements of their respective wire harnesses.

[0151] In some embodiments, such as Figure 6As shown, the battery device 100 includes a wire harness locking clip 110, which is fixedly connected to the mounting boss 104. The wire harness locking clip 110 can be positioned on the side of the mounting boss 104 away from the housing assembly 102, or it can be positioned on the outer periphery, upper side, lower side of the mounting boss 104, or near the wiring port of the electrical connector 106. The wire harness locking clip 110 is used to clamp and limit the wire harness connected to the electrical connector 106, maintaining a predetermined wiring posture near the wiring port. The wire harness locking clip 110 can be fixed to the mounting boss 104 by screwing, snapping, riveting, welding, gluing, embedding, or integral molding. By fixing the wire harness locking clip 110 to the mounting boss 104, the wire harness locking clip 110 and the electrical connector 106 can share the mounting boss 104 as a support base, making the relative position between the wire harness clamping position and the wiring port more stable.

[0152] The wire harness locking clip 110 is located outside the connector port of the electrical connector 106. "Outside the connector port" can be understood as the side of the connector port away from the housing assembly 102, the side from which the wire harness exits the connector port, or the side located in front of the connector port along the opening direction. With the wire harness locking clip 110 located outside the connector port, the wire harness can be clamped and fixed within a short distance after exiting the connector port. Therefore, the portion of the wire harness near the connector port is less prone to large swings and is less likely to be repeatedly subjected to stress on the connection structure at the connector port under vibration, impact, or external pulling.

[0153] The wire harness locking clip 110 is used to clamp a portion of the wire harness near the connector. This portion can be the starting section, root section, section near the plug end, sheath section, or section before bending after the wire harness is connected to the connector. The wire harness locking clip 110 can clamp a single wire harness or multiple wire harnesses simultaneously. For example, when the electrical connector 106 includes a positive connector 1072 and a negative connector 1074, the wire harness locking clip 110 can clamp both the positive and negative wire harnesses simultaneously, or two separate wire harness locking clips 110 can be used to clamp the positive and negative wire harnesses respectively. By clamping the portion of the wire harness near the connector, the swinging and pulling loads of the wire harness can be limited to the outside of the connector, reducing the risk of loosening at the root of the wire harness, terminal misalignment, or connector seal failure.

[0154] The wire harness locking clip 110 is fixed to the mounting boss 104 and located outside the terminal of the electrical connector 106, forming a first fixing point for the wire harness near the terminal. Since the mounting boss 104 itself supports the electrical connector 106, the wire harness locking clip 110 and the electrical connector 106 have a high degree of positional consistency after the wire harness locking clip 110 is fixed to the mounting boss 104. The wire harness is clamped immediately or within a short distance after being led out of the terminal, reducing the possibility of the wire harness swinging to the vicinity of the connecting fold 1026 due to vibration, thereby further maintaining the gap between the wire harness and the connecting fold 1026, improving the anti-wear effect of the wire harness and the reliability of the electrical connection.

[0155] Optionally, the wire harness locking clip 110 may include a clamping base and a clamping cover. The clamping base is fixedly connected to the mounting boss 104, and the clamping cover is detachably connected to the clamping base. The wire harness is clamped between the clamping base and the clamping cover. The clamping cover can be connected to the clamping base by screws, clips, hinges, latches, or elastic claws. The above structure facilitates fixing the wire harness after it has been plugged in, and also facilitates later maintenance or replacement of the wire harness. The wire harness locking clip 110 may include an arc-shaped clamping surface, a semi-circular clamping groove, a U-shaped clamping groove, a V-shaped clamping groove, or multiple wire harness separating grooves. The arc-shaped clamping surface or the semi-circular clamping groove can fit the outer sheath of the circular wire harness, increasing the clamping contact area and reducing the risk of local pressure damage; the multiple wire harness separating grooves can respectively accommodate the positive and negative wire harnesses, keeping the two wire harnesses spaced apart and extending in a parallel direction, thereby reducing wire harness crossing and mutual friction.

[0156] Optionally, an elastic pad, rubber pad, silicone pad, foam pad, insulating pad, or wear-resistant bushing can be provided between the wire harness locking clip 110 and the wire harness. An elastic pad can increase clamping friction, buffer vibration and impact, and reduce the possibility of the wire harness sheath being damaged by the rigid clamping structure. An insulating pad or wear-resistant bushing can further improve the insulation safety and wear resistance of the wire harness clamping area. The wire harness locking clip 110 can also be provided with a guide portion or a limiting portion. The guide portion can be a guide groove, guide arc surface, guide rib, or guide plate, used to guide the wire harness to extend along the opening direction of the connector or the predetermined routing direction. The limiting portion can be a stop protrusion, limiting step, limiting edge, or anti-disengagement clip, used to prevent the wire harness from coming out of the wire harness locking clip 110. The wire harness locking clip 110 can be integrally formed with the mounting boss 104, or it can be fixed to the mounting boss 104 as a separate component; the material can be plastic, nylon, rubber-coated metal, aluminum alloy, steel, or composite material.

[0157] In some embodiments, such as Figure 6As shown, the clamping surface of the wire harness locking clip 110 is provided with an elastic pad 1102. The clamping surface can be a surface in the wire harness locking clip 110 that contacts or is opposite to the outer surface of the wire harness, such as the inner side of the clamping seat, the inner side of the clamping cover, the groove wall of the clamping groove, an arc-shaped clamping surface, a semi-circular clamping surface, a U-shaped clamping surface, or a V-shaped clamping surface. After the elastic pad 1102 is provided on the clamping surface, when the wire harness is clamped by the wire harness locking clip 110, the elastic pad 1102 is located between the wire harness and the rigid or semi-rigid body of the wire harness locking clip 110, thereby forming a flexible clamping and buffer protection for the wire harness.

[0158] The elastic pad 1102 can be a rubber pad, silicone pad, polyurethane pad, foam pad, elastic plastic pad, thermoplastic elastomer pad, sponge pad, foam pad, or composite elastic pad. The elastic pad 1102 can be installed on the clamping surface by bonding, embedding, snap-fitting, overmolding, secondary injection molding, hot pressing, press fitting, or mechanical limiting. The elastic pad 1102 can cover the entire clamping surface or only the local area of ​​the clamping surface in contact with the wire harness. The thickness, hardness, and compression of the elastic pad 1102 can be determined according to the wire harness diameter, wire harness sheath material, clamping force, vibration conditions, and abrasion resistance requirements.

[0159] The elastic pad 1102 can have a contact surface adapted to the shape of the wire harness. The contact surface can be an arc-shaped surface, a semi-circular surface, a corrugated surface, a toothed surface, a raised surface, a textured surface, or a rough, non-slip surface. An arc-shaped or semi-circular surface increases the contact area between the elastic pad 1102 and the circular outer sheath of the wire harness, reducing the clamping pressure per unit area; a corrugated, toothed, raised, or textured surface increases friction, reducing axial movement or circumferential rotation of the wire harness within the wire harness locking clamp 110. By setting a suitable contact surface, the elastic pad 1102 can improve clamping stability while protecting the wire harness sheath.

[0160] The wire harness locking clip 110 is used to clamp a portion of the wire harness near the terminal of the electrical connector 106. With the elastic pad 1102 on the clamping surface, the wire harness does not directly contact the rigid clamping surface of the wire harness locking clip 110. When the wire harness is subjected to vibration, shaking, impact, or external tension, the elastic pad 1102 can absorb some of the impact energy and disperse the clamping pressure, reducing the risk of the wire harness sheath being crushed, worn, or sheared. The elastic pad 1102 can also absorb dimensional deviations through its own compression deformation, ensuring the wire harness is stably clamped without being easily over-compressed. This reduces both the swaying caused by an overly loose wire harness and the damage to the sheath or stress on the internal conductors caused by an overly tight wire harness.

[0161] Optionally, the elastic pad 1102 can be an arc-shaped rubber pad surrounding the outer periphery of the wire harness portion. The arc-shaped rubber pad is disposed within the clamping groove; after the wire harness is placed into the clamping groove, the arc-shaped rubber pad fits against the outer sheath of the wire harness. After the clamping cover is locked, the arc-shaped rubber pad is compressed and forms a flexible clamping effect on the wire harness. The elastic pad 1102 can be disposed on the opposing clamping surfaces of the clamping seat and the clamping cover, or it can be disposed only on the clamping surface of the clamping seat or the clamping surface of the clamping cover. The elastic pad 1102 can be provided with an anti-detachment structure, which can be a snap, rib, undercut, embedded groove, positioning hole, limiting edge, dovetail groove, or covering edge. The elastic pad 1102 can also be made of high and low temperature resistant, oil resistant, salt spray resistant, flame retardant, or insulating materials, such as silicone rubber, EPDM rubber, neoprene rubber, fluororubber, flame retardant rubber, or thermoplastic elastomer materials. The surface of the elastic pad 1102 can be provided with a wear-resistant layer or an anti-slip texture. The wear-resistant layer can be a wear-resistant coating, a nylon layer, a polyurethane layer, or a composite fiber layer. The anti-slip texture can be a horizontal texture, a vertical texture, a mesh texture, a raised dot, or a fine tooth structure.

[0162] In some embodiments, such as Figure 5 As shown, the battery device 100 also includes a protective plate 112, which is fixedly connected to the outer surface of the housing assembly 102. The protective plate 112 can be disposed on the outer surface of the bottom shell 1022, the outer surface of the top cover 1024, the outer surface of the connection between the bottom shell 1022 and the top cover 1024, or on the outer side of the area where the connecting flange 1026 is located. The protective plate 112 can be fixed to the outer surface of the housing assembly 102 by means of screwing, riveting, welding, snap-fitting, bonding, embedding, pressing, or integral molding. By providing the protective plate 112, an additional protective layer can be formed on the outer side of the housing assembly 102 to shield and protect the area near the connecting flange 1026.

[0163] The protective plate 112 covers the side of the connecting flange 1026 facing the terminal of the electrical connector 106. This side of the connecting flange 1026 facing the terminal of the electrical connector 106 is typically the side the wire harness might approach or pass through after being led out from the terminal. With the protective plate 112 covering this side, even if the wire harness shifts towards the connecting flange 1026 due to vibration, shaking, assembly misalignment, or external pulling force, the wire harness preferentially contacts the protective plate 112, rather than directly contacting the edge, flange, weld, corner, or protrusion of the connecting flange 1026. This reduces the risk of the wire harness sheath being scratched, cut, or repeatedly worn by the connecting flange 1026.

[0164] The protective plate 112 can be a metal protective plate, plastic protective plate, rubber protective plate, nylon protective plate, polyurethane protective plate, composite material protective plate, or a protective plate with a wear-resistant coating. The protective plate 112 can have a flat, curved, bent, shell, groove, L-shaped, U-shaped, or encasing structure. The side of the protective plate 112 facing the wire harness can be a smooth surface, a rounded surface, a chamfered surface, a low-friction surface, or an elastic buffer surface to reduce wear when the wire harness contacts the protective plate 112. The edges of the protective plate 112 can be rounded, flanged, edge-wrapped, or flexibly sealed to reduce the possibility of the protective plate 112 forming new sharp edges.

[0165] The gap between the mounting boss 104, the wiring port of the electrical connector 106, and the connecting flange 1026 spatially reduces the probability of the wire harness contacting the connecting flange 1026, while the protective plate 112 provides physical protection on the side of the connecting flange 1026 facing the wiring port. The gap is for avoidance, and the protective plate 112 is for protection. When these two work together, even if the wire harness undergoes significant displacement due to extreme vibration, external impact, or assembly errors, the protective plate 112 can isolate the connecting flange 1026, reducing the possibility of direct hard contact between the wire harness and the connecting flange 1026, thereby improving wear resistance reliability.

[0166] Optionally, the protective plate 112 may extend along the extension direction of the connecting flange 1026 and cover a section of the connecting flange 1026 near the electrical connector 106, or it may cover a longer area of ​​the connecting flange 1026 or the entire side of the connecting flange 1026 facing the terminal, to accommodate scenarios where the wire harness has a large swing range or multiple electrical connectors 106 are arranged side by side. There may be a gap between the protective plate 112 and the connecting flange 1026, or it may be attached to the outside of the connecting flange 1026. A wear-resistant layer or a low-friction layer may be provided on the side of the protective plate 112 facing the terminal of the electrical connector 106. The wear-resistant layer may be a nylon layer, a polyurethane layer, a rubber layer, a polytetrafluoroethylene layer, a wear-resistant coating, or a composite fiber layer.

[0167] In some embodiments, such as Figure 5 As shown, the battery device 100 also includes a sleeve 114. The sleeve 114 is used to cover, protect, and guide the wire harness connected to the electrical connector 106. The sleeve 114 can be a corrugated tube, rubber tube, silicone tube, nylon tube, plastic sheath, braided sleeve, heat shrink sleeve, flame retardant sleeve, abrasion-resistant sleeve, or composite protective sleeve. By providing a sleeve 114 outside the wire harness, an isolation layer can be formed between the wire harness and the external structure, reducing the risk of the wire harness sheath being directly affected by friction, impact, compression, salt spray, dust, or moisture.

[0168] One end of the sleeve 114 engages with the electrical connector 106. The sleeve 114 may have a snap-fit ​​portion at one end, and the electrical connector 106 may have a slot, latch, annular flange, limiting groove, locking step, plug seat, or retaining ring that mates with the snap-fit ​​portion. After the sleeve 114 engages with the electrical connector 106, the end of the sleeve 114 near the connector port can be stably held at the electrical connector 106, preventing it from easily detaching from the vicinity of the connector port due to wire harness vibration, pulling, or swinging. This structure ensures that the root area of ​​the wire harness extending from the connector port of the electrical connector 106 is also covered by the sleeve 114, thereby improving the wear resistance and bending resistance of the wire harness root.

[0169] The other end of the sleeve 114 is a free end extending in a direction away from the electrical connector 106. The free end may not be directly fixed to the electrical connector 106, but may extend along the predetermined routing direction of the wire harness. The free end may extend to the vicinity of the wire harness locking clip 110, wire harness fixing point, adjacent battery device 100, external busbar, cable tray, protective plate, or electrical interface. By setting the other end of the sleeve 114 as a free end, the sleeve 114 can adapt to the arrangement path and bending shape of the wire harness, avoiding excessive rigid constraint at the end away from the electrical connector 106, thereby reducing the risk of bending stress or fatigue damage to the wire harness due to rigid fixation at both ends.

[0170] One end of the sleeve 114 engages with the electrical connector 106, ensuring reliable positioning of the sleeve 114 near the wiring harness connection port. The other end of the sleeve 114 extends away from the electrical connector 106 and serves as a free end, providing continuous protection for the wiring harness along its extension direction. Thus, after the wiring harness exits from the connection port of the electrical connector 106, both the portion near the connection port and the outwardly extending portion are covered by the sleeve 114, reducing the possibility of direct friction between the wiring harness and the connecting flange 1026, the outer surface of the housing assembly 102, the protective plate 112, the edge of the mounting boss 104, or adjacent structures. After the sleeve 114 is fitted over the wiring harness, even if the wiring harness approaches surrounding structures due to vibration, the sleeve 114 will contact the surrounding structures first, thus preventing direct wear on the wiring harness sheath. For high-voltage wiring harnesses, the sleeve 114 also improves insulation protection and safety isolation.

[0171] Optionally, the sleeve 114 can be a corrugated protective tube. The corrugated protective tube has good bending flexibility, allowing it to bend with the wire harness while maintaining external protection. One end of the corrugated protective tube can be engaged with the outer periphery of the wiring port of the electrical connector 106 via a ring-shaped snap, while the other end extends freely along the wire harness. An anti-detachment structure can be provided at the end of the sleeve 114 near the electrical connector 106. This anti-detachment structure can be an annular boss, a barb, an elastic claw, a snap ring, a locking buckle, a limiting rib, or a threaded locking structure. The inner diameter of the sleeve 114 can be larger than the outer diameter of the wire harness to facilitate wire harness insertion; the inner wall of the sleeve 114 can be a smooth surface to reduce friction between the wire harness and the sleeve 114; the outer wall of the sleeve 114 can be a wear-resistant surface, a corrugated surface, or a low-friction surface to improve wear resistance when in contact with external structures. The sleeve 114 can be used with the wire harness locking clamp 110. The wire harness locking clamp 110 can clamp the outer periphery of the sleeve 114 or clamp the local reinforcement section outside the sleeve 114, so that the wire harness and the sleeve 114 are limited and fixed together.

[0172] like Figure 9 As shown, this application also provides a battery assembly 200. The battery assembly 200 includes a plurality of battery devices 100 as described in any of the preceding embodiments, and the plurality of battery devices 100 are arranged along a preset direction. The preset direction can be the length direction, width direction, height direction, array direction, stacking direction, or arrangement direction on the mounting platform of the battery devices 100. The plurality of battery devices 100 can be arranged in a single row, multiple rows, stacked, or arrayed along the preset direction. By arranging the plurality of battery devices 100 along the preset direction, a battery assembly 200 with higher voltage, larger capacity, or greater power output capability can be formed, suitable for vehicles, energy storage devices, ships, construction machinery, communication base stations, or power systems.

[0173] The wiring port of one of two adjacent battery devices 100 is positioned facing the wiring port of the other. The wiring port can be the wiring port of the electrical connector 106, or the wiring port of the positive connector 1072 and / or the wiring port of the negative connector 1074. Positioning the wiring ports of two adjacent battery devices 100 facing each other means that the wiring ports of the two adjacent battery devices 100 are spatially opposite to each other or facing each other, allowing the wiring harness to be connected between the two wiring ports with a shorter path. For example, the wiring port of the first battery device can face the wiring port of the second battery device, and the wiring port of the second battery device can also face the wiring port of the first battery device; or one battery device's wiring port may be angled towards the area where the wiring port of the other battery device is located. With this arrangement, the wiring harness connection path between adjacent battery devices 100 is more direct.

[0174] The wiring harness connecting two adjacent battery devices 100 extends along a straight line or an arc. A straight extension can be understood as the wiring harness exhibiting minimal bending between the two terminals, or only slight offset due to wiring harness flexibility, assembly tolerances, and gravity. An arc extension can be understood as the wiring harness forming a smooth curved path between the two terminals, such as an arc, a gentle arc, an S-curve, or a curved path with continuous curvature changes. The wiring harness extending along a straight line or an arc does not include sharp bends, angular bends, acute-angle bends, or repeated bends near the terminals. By extending the wiring harness along a straight line or an arc, bending stress and assembly difficulty are reduced, improving the reliability of the wiring harness connection.

[0175] Multiple battery devices 100 are arranged in a preset direction, with the wiring port of one of two adjacent battery devices 100 facing the wiring port of the other, so that the wiring harness between adjacent battery devices 100 can be connected along a shorter and smoother path. Since the wiring port of the electrical connector 106 in the battery device 100 can be inclined relative to the side wall 103 of the housing assembly 102, and the wiring harness can be protected by structures such as mounting boss 104, gaps, wiring harness locking clips 110, sleeves 114 or protective plates 112, the wiring harness between adjacent battery devices 100 in the battery assembly 200 can be easily connected directly, and the risk of friction with the connecting fold 1026 or the edge of the housing assembly 102 can be reduced.

[0176] The purpose of arranging multiple battery devices 100 along a preset direction is to achieve modular combination of the battery devices 100. A single battery device 100 can serve as a basic energy storage unit. After multiple battery devices 100 are arranged along the preset direction, they can be combined in series, parallel, or series-parallel to form a battery module 200. The preset direction arrangement makes the positional relationship of each battery device 100 more regular, which facilitates the unified setting of mounting brackets, guide rails, fixing frames, cooling structures, wiring harness channels, protective covers, or electrical busbars. The wiring port of one of two adjacent battery devices 100 faces the wiring port of the other, which can optimize the wiring harness connection path between adjacent battery devices 100. When the wiring harness extends along a straight line, the wiring harness path is shorter, assembly is simpler, the direction of tension transmission is clear, and it is less likely to have local coiling or crossing. When the wiring harness extends along an arc, the smooth curvature can absorb the relative displacement caused by assembly errors, vibration displacement, or thermal expansion and contraction, and avoid sheath cracking, conductor fatigue, or terminal stress caused by sharp angle bending.

[0177] Optionally, multiple battery devices 100 can be arranged sequentially along a first direction, with the sidewalls 103 of two adjacent battery devices 100 facing each other, and the wiring ports on the two opposing sidewalls 103 facing each other. One end of the connecting wire harness is connected to the wiring port of one of the battery devices 100, and the other end is connected to the wiring port of the other battery device 100. The wire harness extends in a substantially straight direction between the two battery devices 100. The above structure is suitable for scenarios where the spacing between adjacent battery devices 100 is small and the height or position of the wiring ports is basically the same, which can reduce the length of the wire harness and the wiring space. Optionally, multiple battery devices 100 can be arranged side by side along a preset direction, with the wiring ports of two adjacent battery devices 100 inclined relative to the sidewalls 103 of their respective housing assemblies 102, and facing the connection area between them respectively. Since the wiring ports are inclined towards each other, the wire harness connecting the two wiring ports can extend along a smooth arc, without the need to form a sharp bend at the root of the wire harness. The above structure is suitable for scenarios where there is a height difference, lateral offset, or large spacing between two adjacent wiring ports, and can absorb positional differences by utilizing the arc extension, improving assembly adaptability.

[0178] Optionally, when the electrical connector 106 includes a positive connector 1072 and a negative connector 1074 arranged adjacently, two adjacent battery devices 100 can be connected via a positive wire harness and a negative wire harness. The terminal of the positive connector 1072 of one battery device 100 can face the corresponding terminal of the other battery device 100, and the terminal of the negative connector 1074 of one battery device 100 can also face the corresponding terminal of the other battery device 100. The positive and negative wire harnesses can extend along straight lines or curves, respectively, and remain parallel or substantially parallel to each other.

[0179] In one embodiment, alternatively, such as Figure 9 and Figure 10 As shown, each battery device 100 includes a positive connector 1072 and a negative connector 1074 arranged adjacent to each other. One end of a wiring harness is connected to the positive connector 1072 of one of the two adjacent battery devices 100, and the other end of the wiring harness is connected to the negative connector 1074 of the other of the two adjacent battery devices 100.

[0180] It is understood that each battery device 100 includes a positive connector 1072 and a negative connector 1074 arranged adjacently. For two adjacent battery devices 100, a wiring harness is provided, with one end of the harness connected to the positive connector 1072 of one battery device 100 and the other end connected to the negative connector 1074 of the other battery device 100. This connection method facilitates the series connection of multiple battery devices 100 to form a battery pack, achieving voltage accumulation and meeting the requirements of high-voltage applications. The adjacent arrangement of the positive connector 1072 and the negative connector 1074 on the battery device 100 helps to shorten the wiring distance of the harness, reduce line resistance, and contribute to the compact layout of the battery devices 100. The positive connector 1072 serves as the positive output interface of the battery device 100, and the negative connector 1074 serves as the negative output interface of the battery device 100; their adjacent arrangement simplifies the internal wire connection. The wiring harness, as a conductive element, enables the transfer of electrical energy from the positive terminal of one battery device 100 to the negative terminal of another battery device 100. Optionally, the positive connector 1072 can be in the form of a positive terminal, a positive plug, or a positive busbar; the negative connector 1074 can be in the form of a negative terminal, a negative plug, or a negative busbar; the wire harness can be a conductive medium such as a cable, wire, busbar, or flexible circuit board.

[0181] It should be added that if there are multiple battery devices 100 arranged in a preset direction, such as multiple battery devices 100 arranged in the direction of gravity, with the positive connector 1072 facing upward and the negative connector 1074 facing downward, then the cable connected to the negative connector 1074 located at the bottom of the entire battery assembly 200 is the total negative cable of this battery assembly 200, and the cable connected to the positive connector 1072 located at the top of the entire battery assembly 200 is the total positive cable of this battery assembly 200.

[0182] like Figure 10 As shown, this application also provides an energy storage device 300. The energy storage device 300 includes a battery device 100 or a battery module 200 as described above, wherein the battery device 100 is used to store electrical energy. The energy storage device 300 can be a residential energy storage device, an industrial / commercial energy storage device, a grid-side energy storage device, a containerized energy storage device, a communication base station energy storage device, a vehicle energy storage device, a marine energy storage device, a mobile energy storage device, or a backup power supply device. By employing a battery device 100 or a battery module 200 in the energy storage device 300, the storage, release, and management of electrical energy can be achieved using the battery device 100, and the electrical connection reliability and wiring harness protection performance of the energy storage device 300 can be improved.

[0183] The energy storage device 300 may include a single battery device 100 or a battery assembly 200 composed of multiple battery devices 100. When the energy storage device 300 includes a single battery device 100, the battery device 100 can function as an independent energy storage unit, receiving electrical energy from an external power source and outputting electrical energy to a load when needed. When the energy storage device 300 includes a battery assembly 200, multiple battery devices 100 can be connected in series, parallel, or series-parallel configurations to improve the output voltage, capacity, power, or redundancy of the energy storage device 300. Multiple battery devices 100 in the battery assembly 200 can be arranged in a predetermined direction and electrically connected via wiring harnesses, electrical connectors 106, copper bars 1068, or busbars.

[0184] The energy storage device 300 may also include a battery management system, a power conversion system, a thermal management system, a fire suppression system, a cabinet, a controller, relays, fuses, circuit breakers, busbars, wiring harnesses, sensors, a communication module, or a monitoring module. The battery management system monitors the voltage, current, temperature, state of charge, health status, or insulation status of the battery device 100; the power conversion system may include an inverter, converter, DC / DC converter module, or charging module to achieve energy conversion; the thermal management system is used for heat dissipation, heating, or temperature equalization of the battery device 100; the cabinet is used to house and secure the battery device 100 or battery assembly 200. All components can work together with the battery device 100 to form a complete energy storage system.

[0185] Since the energy storage device 300 includes a battery device 100 or a battery assembly 200, it can possess the structural advantages of the battery device 100 or the battery assembly 200. For example, the external interface end 1062 of the electrical connector 106 can be inclined relative to the side wall 103 of the housing assembly 102 to optimize the external wiring harness exit direction; a stable conductive path can be formed between the external interface end 1062 and the internal interface end 1064 inside the electrical connector 106 by bending the copper bar 1068; the wiring ports of the positive connector 1072 and the negative connector 1074 can be parallel and form a gap with the connecting fold 1026; the wiring harness locking clip 110, the elastic pad 1102, the protective plate 112, and the sleeve 114 can jointly improve the wiring harness's anti-wear and vibration resistance reliability. Therefore, the energy storage device 300 has high safety under long-term charging and discharging and vibration environments.

[0186] The battery device 100 is used to store electrical energy for temporary energy storage and dispatch. When electricity prices are low, photovoltaic power generation is sufficient, wind power output is high, or external power sources are available, the energy storage device 300 can store electrical energy in the battery device 100. During peak electricity prices, when load demand increases, external power is interrupted, or renewable energy output is insufficient, the energy stored in the battery device 100 can be released to supply power to the load or the grid. Through the charging and discharging of the battery device 100, the energy storage device 300 can improve energy utilization efficiency and power supply stability.

[0187] Optionally, the energy storage device 300 can be a residential energy storage cabinet, with the battery device 100 or battery assembly 200 housed inside the cabinet, and the electrical connector 106 arranged facing the wiring harness channel inside the cabinet. Because the connection port can be tilted and has an anti-wear structure, the wiring harness can be connected to the power conversion module or power distribution module more smoothly inside the cabinet, reducing sharp bends and wear. Optionally, the energy storage device 300 can be a containerized energy storage system, with multiple battery assemblies 200 arranged and installed inside the container. The battery assemblies 200 are connected by wiring harnesses or busbars, and the wiring harnesses can extend along straight lines or curves, improving assembly efficiency and maintenance convenience. The energy storage device 300 can also be applied to scenarios with high vibration, such as vehicles, ships, or construction machinery. Multiple protections are provided for the wiring harness using gaps, wiring harness locking clips 110, elastic pads 1102, protective plates 112, and sleeves 114, reducing the risk of friction between the wiring harness and the connecting fold 1026 or the outer surface of the housing assembly 102 under vibration.

[0188] like Figure 11 As shown, this application also provides an electrical device 400. The electrical device 400 includes a battery device 100 or a battery assembly 200 as described above, wherein the battery device 100 provides electrical energy. The electrical device 400 can be a vehicle, construction machinery, ship, drone, robot, mobile energy storage device, communication equipment, industrial equipment, household appliances, medical equipment, power tools, agricultural machinery, or any device requiring electrical power to drive or supply. By incorporating the battery device 100 or battery assembly 200 into the electrical device 400, electrical energy can be provided to the power system, control system, lighting system, communication system, actuator, or electrical load of the electrical device 400.

[0189] Electrical device 400 may include a single battery device 100 or a battery assembly 200 composed of multiple battery devices 100. When electrical device 400 includes a single battery device 100, the battery device 100 can supply power to electrical device 400 as an independent power supply unit. When electrical device 400 includes a battery assembly 200, multiple battery devices 100 can be connected in series, parallel, or series-parallel configurations to meet the electrical device 400's requirements for voltage, capacity, power, battery life, or redundant power supply. Multiple battery devices 100 in battery assembly 200 can be arranged along a preset direction, and the wiring harnesses between adjacent battery devices 100 can extend along straight lines or curves, thereby improving the neatness of the wiring harness arrangement and the ease of assembly.

[0190] Electrical equipment 400 may also include electrical loads, controllers, power conversion modules, motors, transmission systems, actuators, sensors, communication modules, display modules, cooling systems, charging interfaces, power distribution modules, or protection modules. Battery device 100 can be connected to the electrical load or power conversion module via electrical connector 106 to provide DC power to electrical equipment 400, or provide adapted power after conversion by power conversion devices such as inverters, converters, or DC / DC conversion modules. Battery device 100 can also cooperate with a battery management system to monitor and protect against voltage, current, temperature, state of charge, health status, and insulation status.

[0191] Since the electrical equipment 400 includes a battery device 100 or a battery assembly 200, it can possess the structural advantages of the battery device 100 or battery assembly 200. For example, the electrical connector 106 can be mounted on the outside of the housing assembly 102 via a mounting boss 104, creating a gap between the wiring port and the connecting flange 1026; the wiring port can be angled relative to the side wall 103 of the housing assembly 102 to optimize the wire harness exit direction; the wire harness locking clip 110, the elastic gasket 1102, the protective plate 112, and the sleeve 114 can collectively reduce the risk of wire harness wear; the conductive connector 1066 or the copper bar 1068 can form a stable conductive path between the electrical connector 106 and the internal electrical connectors of the housing assembly 102. Therefore, the electrical equipment 400 can maintain high power supply reliability and safety under operating vibration, shock, or movement conditions.

[0192] The battery unit 100 provides electrical energy to power various functional modules of the electrical equipment 400. For example, in a vehicle, the battery unit 100 can provide power to the drive motor, on-board controller, air conditioning system, lighting system, and low-voltage power supply system; in a ship, the battery unit 100 can provide power to the propulsion system, navigation system, and shipboard electrical equipment; in a robot or unmanned equipment, the battery unit 100 can provide power to motion actuators, sensors, and communication modules. Because the battery unit 100 has good wire harness abrasion resistance and reliable electrical connections, the risk of power outages, poor contact, or insulation failure in the electrical equipment 400 during long-term operation is low.

[0193] Optionally, the electrical equipment 400 can be a vehicle, with the battery device 100 or battery pack 200 installed in the frame, chassis, cargo box, or battery compartment. During vehicle operation, there are vibrations, impacts, and muddy environments. The battery device 100 protects the wiring harness through gaps, protective plates 112, sleeves 114, and wiring harness locking clips 110, reducing the risk of short circuits caused by wear on the wiring harness and connecting folds 1026, thus improving overall vehicle safety. Optionally, the electrical equipment 400 can be construction machinery or agricultural machinery, with the battery device 100 supplying power to hydraulic pumps, motors, controllers, or actuators, and adapting to high-vibration and high-dust environments through a reliable electrical connection structure. Optionally, the electrical equipment 400 can be a ship or marine equipment, with the battery device 100 or battery pack 200 installed within the hull to supply power to propulsion motors, navigation systems, communication equipment, or lighting equipment. Optionally, the power supply equipment 400 can be a mobile robot, drone, inspection equipment, or portable power supply equipment. By using the battery device 100 or battery assembly 200, the wiring harness can be arranged along a smoother path, reducing sharp bends and wear. At the same time, the structure of the electrical connector 106 and copper bar 1068 improves the stability of power transmission, enabling the equipment to maintain reliable power supply during movement, turning, or vibration.
