Description

Battery devices, energy storage devices, energy storage systems, electrical devices and charging networks Technical Field

[0001] This application relates to the field of battery device technology, and in particular to a battery device, energy storage device, energy storage system, power consumption device and charging network. Background Technology

[0002] The distribution box is a key component in the power system. In battery devices, the distribution box can distribute the electrical energy in the individual battery modules to the various high-voltage systems of external electrical devices.

[0003] During the operation of the battery unit, the power distribution box may malfunction, thus requiring maintenance. In related technologies, the power distribution box is built into the battery unit. Maintenance of the power distribution box requires disassembling the external casing of the battery unit and removing the power distribution box from the casing through cumbersome procedures. This results in a complicated disassembly process, poor ease of disassembly, and an adverse impact on maintenance efficiency.

[0004] Summary of the Invention

[0005] The purpose of this application is to provide a battery device, energy storage device, energy storage system, power consumption device, and charging network, aiming to solve the technical problems of cumbersome and inconvenient disassembly process of power distribution components in battery devices, which affects disassembly and assembly efficiency. Technical solutions

[0006] The technical solution adopted in the embodiments of this application is:

[0007] In a first aspect, this application provides a battery device, comprising:

[0008] Battery cell assembly;

[0009] The enclosure has a housing space and an installation space. The battery cell assembly is housed in the housing space, and the enclosure has an interface that connects to the installation space.

[0010] The first guide is connected to the housing and located within the installation space, and the first guide is electrically connected to the battery cell assembly.

[0011] The power distribution assembly includes a housing, an electronic system assembly, and a second conductor. The housing has a receiving cavity, the electronic system assembly is connected to the housing and housed in the receiving cavity, and the second conductor is electrically connected to the electronic system assembly. The housing is connected to a box and is inserted into an installation space via a plug-in interface, and the second conductor is electrically connected to a first conductor. The housing has an operating port.

[0012] A locking assembly is connected between the housing and the enclosure, or the locking assembly is connected between the first guide and the second guide; the operating port extends through the locking assembly.

[0013] In this embodiment, the locking assembly is connected between the housing and the enclosure or between the first and second guide members, thereby keeping the first and second guide members connected. The operating port extends to the location of the locking assembly. During maintenance, the operator's hand or handheld tool can directly contact the locking assembly through the operating port to remove and install the locking assembly. After the locking assembly is unlocked, the power distribution assembly is relatively free relative to the enclosure. The first and second guide members separate, and the power distribution assembly can be directly detached from the plug-in interface of the installation space without disassembling the enclosure. The removal and installation of the power distribution assembly and the enclosure are more convenient, which helps to improve maintenance efficiency.

[0014] In one embodiment, the second guide is housed in the receiving cavity, the locking assembly is disposed in the receiving cavity, and the operating port extends into the receiving cavity and is disposed opposite to the locking assembly.

[0015] In this embodiment, the locking assembly is configured inside the receiving cavity. The operating port only needs to extend into the receiving cavity and be positioned opposite the locking assembly. The operator's hand or tool can then pass through the operating port into the receiving cavity to contact the locking assembly, thereby enabling the installation and disassembly of the locking assembly. The overall structural design is simpler and more compact.

[0016] In one embodiment, the power distribution assembly further includes a cover that is detachably connected to the housing and covers the operating port.

[0017] In this embodiment, the cover is opened on the operating port, thereby sealing the accommodating cavity and protecting the electronic system components, some of the first guide, the second guide, and the locking assembly located in the accommodating cavity, reducing the probability of damage to the various components in the accommodating cavity by moisture, dust, foreign objects, etc.

[0018] In one embodiment, the first conductor includes a second conductor piece electrically connected to the battery cell assembly, the second conductor includes a second conductor piece electrically connected to the electronic system assembly, the first conductor piece and the second conductor piece are in contact connection; a locking assembly is connected between the first conductor piece and the second conductor piece.

[0019] In this embodiment, the first guide member adopts the structure of a first guide piece, which facilitates the insertion of the first guide piece into the receiving cavity. The second guide member adopts the structure of a second guide piece, which facilitates the extension of the second guide piece to the position connected with the first guide piece when the electronic system components are far away from the second guide piece. This makes the overall structure more flexible and versatile, and easier to manufacture and assemble.

[0020] In one embodiment, the locking assembly includes a first locking structure and a second locking structure. The first locking structure is connected to a first guide member, and the second locking structure is connected to a second guide member. The first locking structure and the second locking structure are threadedly connected so that the first guide piece and the second guide piece are positioned between the first locking structure and the second locking structure.

[0021] In this embodiment, the locking assembly adopts a threaded connection, which makes the installation and disassembly of the locking assembly more convenient, thereby improving the efficiency of installation and disassembly between the power distribution assembly and the enclosure.

[0022] In one embodiment, either the first locking structure or the second locking structure is a stud structure, and the other is a nut structure, with the stud structure and the nut structure being threadedly connected.

[0023] In this embodiment, the locking assembly includes a stud structure and a nut structure. The threaded connection between the stud structure and the nut structure enables the limiting and fixing of the first guide and the second guide. The structure is simple, easy to manufacture, and convenient to install and disassemble, which helps to improve maintenance efficiency.

[0024] In one embodiment, the first locking structure is a stud structure, the second locking structure is a nut structure, and the locking assembly also includes an insulating seat connected to the housing, with the stud structure connected to the insulating seat.

[0025] In this embodiment, the insulating base can support the stud structure and the first conductive piece, and can insulate the stud structure and the first conductive piece from the housing, reducing the risk of short circuit between the stud structure and the housing.

[0026] In one embodiment, the battery device further includes a guide assembly connected between the housing and the casing.

[0027] In this embodiment, by adding a guide structure between the box and the shell, the shell can move more smoothly in and out of the installation space, reducing interference problems during the sliding process and improving assembly efficiency.

[0028] In one embodiment, the guide assembly includes a first guide structure connected to the housing and a second guide structure connected to the box body. The first guide structure and the second guide structure are plugged into each other. The first guide structure is slidable relative to the second guide structure along a first direction, which is parallel to the depth direction of the plug-in interface.

[0029] In this embodiment, the guide component adopts a combination of a first guide structure and a second guide structure that are inserted and slidably engaged. The structure is simple and easy to manufacture, and the configuration of the first guide structure and the second guide structure is more flexible.

[0030] In one embodiment, the battery device further includes a limiting component connected between the housing and the enclosure, the limiting component being used to limit movement of the housing relative to the enclosure in a second direction perpendicular to the depth direction of the insertion interface.

[0031] In this embodiment, by setting a limiting component between the shell and the box, the movement of the shell relative to the box in the second direction can be restricted, thereby reducing the shaking of the shell relative to the box, protecting the shell, and helping to reduce noise.

[0032] In one embodiment, the limiting component includes a first limiting structure connected to the housing and a second limiting structure connected to the box body, wherein the first limiting structure and the second limiting structure are inserted into each other along a first direction.

[0033] In this embodiment, when the housing is inserted into the installation space, the first limiting structure and the second limiting structure are inserted to limit the housing, thereby reducing the shaking of the housing relative to the box, protecting the housing, and helping to reduce noise.

[0034] In one embodiment, the housing includes a housing body and a panel portion. The housing body has an accommodating space, an electronic system component is connected to the housing body, and a locking component is connected between the housing body and the enclosure. The panel portion is connected to the housing body, the housing body is inserted into the mounting space, the panel portion is exposed outside the mounting space, and the edge of the panel portion extends to the periphery of the insertion interface and is connected to the surface of the housing body.

[0035] In this embodiment, by adding a panel, after the shell body in the housing is inserted into the installation space, the panel can seal the gap between the shell body and the installation space at the insertion interface of the installation space, thereby improving the sealing performance of the battery device.

[0036] In one embodiment, the housing includes a frame and a cover. The cover is detachably connected to the frame and together with the frame forms an accommodating space and an installation space. An insertion interface is provided on the frame, and an open opening is provided on the housing to communicate with the accommodating cavity. The open opening is positioned opposite to the cover.

[0037] In this embodiment, the enclosure adopts a combination of a cover and a frame. Opening the cover exposes the installation space and the accommodating cavity through the opening, so that electronic system components, second conductors, and locking components are exposed as much as possible in a position accessible to the operator. This makes it easier to maintain the power distribution components when the cover is opened.

[0038] In one embodiment, the cover includes a first sub-cover and a second sub-cover connected to the first sub-cover. Both the first and second sub-covers are detachably connected to the frame. The first sub-cover is disposed opposite to the battery cell assembly, and the second sub-cover is disposed opposite to the opening.

[0039] In this embodiment, when the power distribution component needs to be repaired, only the second sub-cover needs to be opened, so that the power distribution component and its internal electronic system components, second conductors and locking components can be exposed, thus making it less likely to affect the environment of the battery cell components and protecting the battery cell components.

[0040] In one embodiment, the housing includes a first sub-housing section and a second sub-housing section. The first sub-housing section has an accommodating space, and the second sub-housing section has an installation space. The housing and the first guide are both connected to the second sub-housing section, and the second sub-housing section is detachably connected to the first sub-housing section.

[0041] In this embodiment, the enclosure is constructed by combining a first sub-enclosure and a second sub-enclosure, which allows the second sub-enclosure to be disassembled separately when repairing the power distribution components, making the repair more convenient and labor-saving.

[0042] Secondly, this application provides an energy storage device, including a plurality of battery devices as described above, the battery devices being used to store or provide electrical energy.

[0067] A battery apparatus may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells connected in series, parallel, or mixed connections via busbars.

[0068] The battery device can be a battery pack, which generally includes a housing and one or more individual battery cells housed in the housing.

[0069] Distribution boxes are key components in power systems. They are also known as high-voltage boxes. In battery devices, distribution boxes can distribute the electrical energy from individual battery cells to the high-voltage systems of external electrical devices.

[0070] Distribution boxes typically contain numerous circuit protection devices, such as relays and fuses. During the operation of the battery device, fuses and relays often fail when dangerous situations occur that threaten the normal operation of the battery device, causing the distribution box to malfunction. Therefore, distribution boxes frequently require maintenance.

[0071] In related technologies, the power distribution box is built into the battery device. For example, the battery device includes a housing with a accommodating space, and the power distribution box is housed inside the housing. When repairing the power distribution box, the housing outside the battery device needs to be disassembled to expose the power distribution components. The power distribution box is often fixed to the housing by fastening components. Therefore, maintenance personnel need to use tools and go through cumbersome procedures to remove the power distribution box from the housing before performing maintenance, which makes the maintenance process cumbersome, inconvenient, and has an adverse impact on maintenance efficiency.

[0072] Therefore, this application provides a battery device. In this example, the battery device includes a power distribution component (i.e., a power distribution box). The power distribution component is plugged into an installation space on the housing. Within the installation space, the power distribution component is electrically connected to a first guide member via a second guide member, enabling electrical connection between the power distribution component and the individual battery cells. The first and second guide members are also locked together by a locking component. When repairing the power distribution component, it is only necessary to open the locking component and pull the power distribution component with external force to remove it from the installation space. The power distribution component can be removed without disassembling the housing, thereby improving the convenience of installation and removal of the power distribution component and improving maintenance efficiency.

[0073] Specifically, referring to FIG2, this application embodiment provides a battery device 1100, which includes one or more battery cell assemblies 1120. The battery device 1100 disclosed in this application embodiment can be used in electrical devices that use the battery device 1100 as a power source or in various energy storage devices and energy storage systems that use the battery device 1100 as an energy storage element. Electrical devices can be, but are not limited to, mobile phones, portable devices, laptops, electric toys, power tools, electric vehicles, vehicles, ships, spacecraft, etc. Electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric boat toys, and electric airplane toys, etc. Spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0074] For ease of explanation, the following embodiments will be described using a vehicle 1000 as an example of an electrical device according to an embodiment of this application.

[0075] Please refer to Figure 1, which is a structural schematic diagram of a vehicle 1000 provided in some embodiments of this application. The vehicle 1000 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. A battery device 1100 is provided inside the vehicle 1000, and the battery device 1100 can be located at the bottom, front, or rear of the vehicle 1000. The battery device 1100 can be used to power the vehicle 1000; for example, the battery device 1100 can serve as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller and a motor. The controller is used to control the battery device 1100 to supply power to the motor, for example, to meet the power needs of the vehicle 1000 during startup, navigation, and driving.

[0076] In some embodiments of this application, the battery device 1100 can not only serve as the operating power source for the vehicle 1000, but also as the driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0077] Please refer to Figure 2, which is an exploded structural diagram of a battery device 1100 provided in some embodiments of this application. The battery device 1100 includes a housing 1110 and a battery cell assembly 1120. A receiving space 1113 is formed within the housing 1110, and the battery cell assembly 1120 is housed within the receiving space 1113. The battery cell assembly 1120 is typically formed by arranging multiple battery cells. Alternatively, the battery cell assembly 1120 can also be a battery module, which is formed by arranging and fixing multiple battery cells to form an independent module. As an example, a battery module can be formed by binding multiple battery cells together with cable ties. The housing 1110 provides the receiving space 1113 for the battery cell assembly 1120, and the housing 1110 can adopt various structures.

[0078] A battery cell refers to the smallest unit that makes up the battery device 1100. Each battery cell can be a secondary battery cell or a primary battery cell; it can also be a lithium-sulfur battery cell, a sodium-ion battery cell, or a magnesium-ion battery cell, but is not limited to these. Battery cells can be cylindrical, flat, cuboid, or other shapes.

[0079] According to some embodiments of this application, referring to Figures 2-5, this application provides a battery device 1100, which includes a battery cell assembly 1120, a housing 1110, a first conductive member 1130, a power distribution assembly 1140, and a locking assembly 1150. The housing 1110 has an accommodating space 1113 and an mounting space 1114. The battery cell assembly 1120 is housed within the accommodating space 1113, and the housing 1110 has a plug-in interface 1115 communicating with the mounting space 1114. The first conductive member 1130 is connected to the housing 1110 and located within the mounting space 1114, and is electrically connected to the battery cell assembly 1120. The power distribution assembly 1140 includes a housing 1141, ... The electronic system component 1144 and the second guide member 1143 are included. The housing 1141 has a receiving cavity 11411. The electronic system component 1144 is connected to the housing 1141 and housed in the receiving cavity 11411. The second guide member 1143 is electrically connected to the electronic system component 1144. The housing 1141 is connected to the enclosure 1110 and is inserted into the installation space 1114 by a plug-in interface 1115. The second guide member 1143 is electrically connected to the first guide member 1130. The housing 1141 has an operation port 11415. A locking assembly 1150 is connected between the housing 1141 and the enclosure 1110, or the locking assembly 1150 is connected between the first guide member 1130 and the second guide member 1143. The operation port 11415 extends to the locking assembly 1150.

[0080] For the housing 1110, which is used to accommodate the battery cell assembly 1120, the housing 1110 may include a first part 1111 and a second part 1112, which overlap each other, and together define an accommodating space 1113 for accommodating the battery cell assembly 1120. The second part 1112 may be a hollow structure with one end open, and the first part 1111 may be a plate-like structure, with the first part 1111 covering the open side of the second part 1112, so that the first part 1111 and the second part 1112 together define the accommodating space 1113; the first part 1111 and the second part 1112 may also both be hollow structures with one side open, with the open side of the first part 1111 covering the open side of the second part 1112. Of course, the box 1110 formed by the first part 1111 and the second part 1112 can be of various shapes, such as cylinder, cuboid, etc.

[0081] The housing 1110 has a accommodating space 1113 for accommodating the battery cell assembly 1120. The housing 1110 also has an installation space 1114 for accommodating the power distribution assembly 1140. The installation space 1114 can be cavity-shaped or groove-shaped. The plug-in interface 1115 is opened on the housing wall of the housing 1110, so that the plug-in interface 1115 is connected to the installation space 1114. It can be understood that the installation space 1114 forms a groove-shaped space structure. The mounting space 1114 and the accommodating space 1113 can be configured to be either interconnected or non-interconnected. For example, if the insertion interface 1115 of the mounting space 1114 can be sealed, such as if the insertion interface 1115 of the mounting space 1114 can be sealed by the panel portion 11412 described below, then the mounting space 1114 can be configured to be interconnected with the accommodating space 1113. If the insertion interface 1115 of the mounting space 1114 is connected to the external space and is not sealed, then the mounting space 1114 can be configured to be non-interconnected and isolated from the accommodating space 1113.

[0082] The battery cell assembly 1120 is housed in the housing space 1113 of the housing 1110. When the battery cell assembly 1120 supplies power to external electrical components, it first needs to be electrically connected to the power distribution assembly 1140. Therefore, it is known that the battery device 1100 needs to be equipped with a first conductive member 1130 to be electrically connected to the battery cell assembly 1120, so that the power distribution assembly 1140 can be electrically connected and connected to the battery cell assembly 1120 through the first conductive member 1130. The first conductor 1130 can be understood as a plug-in terminal or pin structure or a socket for electrical connection. The first conductor 1130 can also be a simple metal structural component that can conduct electricity. The first conductor 1130 is connected to the housing 1110. Specifically, the housing 1110 may have a beam structure or stiffening plate structure inside. The first conductor 1130 can be fixedly or detachably connected to the beam structure or stiffening plate structure.

[0083] In the power distribution assembly 1140, the electronic system assembly 1144 consists of the various basic parts of the electronic system that constitute the power distribution assembly 1140. For example, the electronic system assembly 1144 includes voltage regulators, sensors, amplifiers, signal processors, relays, fuses, circuit breakers, memory, resistors, capacitors, and wireless modules.

[0084] In the power distribution assembly 1140, the housing 1141 is used to house the aforementioned electronic system assembly 1144. The housing 1141 has an internal cavity 11411, within which the electronic system assembly 1144 is housed. The electronic system assembly 1144 and the housing 1141 are fixedly or detachably connected, thereby fixing the position of the electronic system assembly 1144 relative to the housing 1141 within the cavity 11411. The housing 1141 can be fabricated using a plate-like structure and can be made of metallic or non-metallic materials. For example, the housing component can be made of materials such as iron, aluminum, alloys, or plastics. Since the power distribution component 1140 is inserted into the installation space 1114 of the enclosure 1110, the size of the housing 1141 must match the size of the installation space 1114 so that the housing 1141 can be inserted into the installation space 1114 along the depth direction of the insertion interface 1115, where the depth direction is the insertion direction.

[0085] In the power distribution assembly 1140, the second conductor 1143 is used to make an electrical connection with the first conductor 1130. The second conductor 1143 is also electrically connected to the electronic system assembly 1144. After the power distribution assembly 1140 is inserted into the installation space 1114, the electronic system assembly 1144 can realize the electrical connection with the battery cell assembly 1120 through the electrical connection of the first conductor 1130 and the second conductor 1143. The second connector 1143 can also be a plug-in terminal, pin structure, or electrical connection socket, etc. The second connector 1143 can also be a simple, conductive metal structure. Of the first connector 1130 and the second connector 1143, one can be a male connector and the other a female connector, allowing the first connector 1130 and the second connector 1143 to be connected by a plug-in connection. Optionally, the electrical connection between the first connector 1130 and the second connector 1143 can also be achieved through contact or abutment. The second connector 1143 is fixedly or detachably connected to the housing 1141.

[0086] The locking assembly 1150 is used to limit the connection of the power distribution assembly 1140 to the enclosure 1110. Therefore, the locking assembly 1150 can be connected between the housing 1141 and the enclosure 1110. Since the first conductor 1130 connects to the second conductor 1143 when the power distribution assembly 1140 is connected to the enclosure 1110, and the second conductor 1143 is indirectly connected to the housing 1141 via the electronic system assembly 1144, the locking assembly 1150 can also be connected between the first conductor 1130 and the second conductor 1143. The locking assembly 1150 limits the first conductor 1130 relative to the second conductor 1143, which is equivalent to limiting the connection between the enclosure 1110 and the housing 1141. The locking assembly 1150 can be understood as a type of fastener. For example, the locking assembly 1150 can be a threaded fastener, a snap-fit ​​structure, a bolted limiting structure, etc.

[0087] The housing 1141 of the power distribution assembly 1140 is also provided with an operating port 11415, which can be a hole structure formed in the shell wall of the housing 1141. The operating port 11415 is used to observe the locking assembly 1150 and to perform operations such as installation and removal of the locking assembly 1150 by operating tools. The operating port 11415 can be understood as an operating channel. Therefore, the operating port 11415 needs to be able to extend to the locking assembly 1150 or the location of the locking assembly 1150 so that the operator's hand or the tool in hand can contact the locking assembly 1150 to perform operations such as installation and removal of the locking assembly 1150.

[0088] In this embodiment, the power distribution assembly 1140 is inserted into the installation space 1114 of the housing 1110. The first conductor 1130 and the second conductor 1143 are electrically connected to achieve electrical connection between the battery cell assembly 1120 and the power distribution assembly 1140. The locking assembly 1150 is connected between the housing 1141 and the housing 1110 or between the first conductor 1130 and the second conductor 1143, thereby keeping the first conductor 1130 and the second conductor 1143 connected. An operation port 11415 is provided on the housing 1141 of the power distribution assembly 1140, and the operation port 11415 extends to the locking assembly. The location of component 1150 allows the operator's hand or handheld tool to directly access the locking assembly 1150 through the operating port 11415 during maintenance, enabling the removal and installation of the locking assembly 1150. After the locking assembly 1150 is unlocked, the power distribution assembly 1140 is relatively free relative to the enclosure 1110. The first guide 1130 and the second guide 1143 separate, allowing the power distribution assembly 1140 to be directly detached from the plug-in interface 1115 of the installation space 1114 without disassembling the enclosure 1110. This makes the removal and installation of the power distribution assembly 1140 and the enclosure 1110 more convenient and improves maintenance efficiency.

[0089] In some embodiments, as shown in FIG3-5, the second guide member 1143 is accommodated in the accommodating cavity 11411, the locking assembly 1150 is disposed in the accommodating cavity 11411, and the operating port 11415 extends into the accommodating cavity 11411 and is disposed opposite to the locking assembly 1150.

[0090] Specifically, the electronic system component 1144 is located within the accommodating cavity 11411, and the second guide 1143 is connected to the electronic system component 1144, so that the second guide 1143 is also located within the accommodating cavity 11411. Therefore, the first guide 1130 needs to extend through the shell wall of the housing 1141 into the accommodating cavity 11411 and connect with the second guide 1143. The first guide 1130 can be columnar, rod-shaped, or sheet-shaped, etc. An insertion hole is opened on the shell wall of the housing 1141, and the first guide 1130 is inserted into the insertion hole and makes contact with the second guide 1143. The contact method can include fitting and abutting, insertion, etc.

[0091] For the locking assembly 1150, when the locking assembly 1150 is connected between the first guide member 1130 and the second guide member 1143, since the second guide member 1143 is located in the receiving cavity 11411, the locking assembly 1150 will also be located in the receiving cavity 11411. Therefore, it is necessary to make the operating port 11415 able to penetrate into the receiving cavity 11411, so that the operating port 11415 is opposite to the locking assembly 1150, so that the operator's hand or the tool in hand can pass through the operating port 11415 and directly extend to the position of the locking assembly 1150, thereby installing and removing the locking assembly 1150. When the locking assembly 1150 is connected between the housing 1141 and the box 1110, the locking assembly 1150 can also be located within the receiving cavity 11411. For example, the locking assembly 1150 includes a stud and a nut. The nut is fixed on the box 1110. A through hole or threaded hole is opened on the housing 1141. The stud enters the receiving cavity 11411 through the operating port 11415 and passes through the through hole or threaded hole, so that the stud and the nut are threadedly connected, thereby limiting the box wall of the box 1110 and the shell wall of the housing 1141 between the stud and the nut.

[0092] In this embodiment, the locking assembly 1150 is disposed in the receiving cavity 11411. The operating port 11415 only needs to extend into the receiving cavity 11411 and be positioned opposite to the locking assembly 1150. The operator's hand or tool can then pass through the operating port 11415 into the receiving cavity 11411 to contact the locking assembly 1150, thereby enabling the installation and removal of the locking assembly 1150. The overall structural design is simpler and more compact.

[0093] In some embodiments, as shown in Figures 3, 5, 6 and 7, the power distribution assembly 1140 further includes a cover 1142, which is detachably connected to the housing 1141 and covers the operating port 11415.

[0094] Since the operating port 11415 is an exposed opening structure, when there are many impurities in the external environment of the battery device 1100, such as dust and moisture, they can easily enter the receiving cavity 11411 through the operating port 11415. If the receiving cavity 11411 is connected to the receiving space 1113, they may even enter the receiving space 1113. Therefore, in this example, a cover 1142 is added to the power distribution assembly 1140. The cover 1142 is used to cover the operating port 11415 to seal it. The cover 1142 is detachably connected to the housing 1141. When maintenance is not required, the cover 1142 is placed on the operating port 11415. When maintenance or disassembly of the locking assembly 1150 is required, the cover 1142 is removed from the housing 1141, and the operating port 11415 is exposed.

[0095] The cover 1142 may be a plate-like structure, and a handle or other structure may be connected to the outer surface of the cover 1142 to facilitate the operator to grip and apply force when installing and removing the cover 1142.

[0096] The cover 1142 can be made of transparent or opaque material. When the cover 1142 is made of transparent material, the operator can observe the situation inside the accommodating cavity 11411 through the cover 1142. Since the electronic system component 1144, the second guide 1143 and the first guide 1130 all have at least a portion located inside the accommodating cavity 11411, the operation of the electronic system component 1144 and the connection between the first guide 1130 and the second guide 1143 can be observed through the cover 1142 without opening the cover 1142.

[0097] In this embodiment, the cover 1142 is opened on the operating port 11415, thereby sealing the accommodating cavity 11411 and protecting the electronic system components 1144, part of the first guide 1130, the second guide 1143, and the locking assembly 1150 located in the accommodating cavity 11411, reducing the probability of damage to the various components in the accommodating cavity 11411 by moisture, dust, foreign objects, etc.

[0098] In some embodiments, referring to Figures 5 and 7, the first conductor 1130 includes a second conductor piece electrically connected to the battery cell assembly 1120, the second conductor 1143 includes a second conductor piece electrically connected to the electronic system assembly 1144, the first conductor piece and the second conductor piece are in contact connection; the locking assembly 1150 is connected between the first conductor piece and the second conductor piece.

[0099] Specifically, the first conductive piece 1130 adopts a sheet-like extended first conductive piece, which can be made of a metal material to have conductivity. One end of the first conductive piece is electrically connected to the battery cell assembly 1120, and the other end of the first conductive piece abuts against the second conductive piece. The first conductive piece can be fixedly connected to the housing 1110, and one end of the first conductive piece can extend into the receiving cavity 11411. The second conductive piece is located in the receiving cavity 11411. The second conductive piece has a sheet-like structure and also needs to be made of a metal material, such as copper sheet, aluminum sheet, etc. Copper sheet can also be called copper busbar.

[0100] The first and second guide pieces can contact each other by abutting, plugging, etc. For example, the first and second guide pieces are arranged opposite to each other and attached to each other, so that a large contact area is formed between the first and second guide pieces.

[0101] The locking assembly 1150 is connected between the first guide piece and the second guide piece, thereby enabling the connection and fixation between the first guide piece and the second guide piece. The locking assembly 1150 may adopt a fastening structure independent of the first guide piece and the second guide piece, and the locking assembly 1150 is connected between the first guide piece and the second guide piece by assembly.

[0102] In this embodiment, the first guide member 1130 adopts the structure of a first guide piece, which facilitates the insertion of the first guide piece into the receiving cavity 11411. The second guide member 1143 adopts the structure of a second guide piece, which facilitates the extension of the second guide piece to a position connected with the first guide piece when the electronic system component 1144 is far away from the second guide piece. This makes the overall structure more flexible and versatile, and easier to manufacture and assemble.

[0103] In some embodiments, referring to Figures 6 and 7, the locking assembly 1150 includes a first locking structure 1151 and a second locking structure 1152. The first locking structure 1151 is connected to the housing 1110, and the first locking structure 1151 and the second locking structure 1152 are threadedly connected so that the first guide piece and the second guide piece are limited to be located between the first locking structure 1151 and the second locking structure 1152.

[0104] In this example, the locking assembly 1150 is connected between the first guide piece and the second guide piece. Specifically, the first locking structure 1151 in the locking assembly 1150 is connected to the housing 1110, specifically to the stiffening plate or beam in the housing 1110. The second locking structure 1152 is connected to the second guide piece. The connection can include a fixed connection and a movable connection. For example, a fixed connection can include welding, bonding, or integral molding. A movable connection includes an abutting method. That is, after the second locking structure 1152 is connected to the first locking structure 1151, the second locking structure 1152 can abut against the second guide piece, so that the first guide piece (i.e., the first guide member 1130) and the second guide piece (i.e., the second guide member 1143) are limited to the first locking structure 1151 and the second locking structure 1152 after contact.

[0105] The first locking structure 1151 and the second locking structure 1152 are connected by a threaded connection. For example, one of the first locking structure 1151 and the second locking structure 1152 has an external thread, while the other has an internal thread. The internal thread and the external thread are matched and connected to limit the positioning of the first guide piece and the second guide piece. Disassembly is achieved by rotating the first locking structure 1151 relative to the second locking structure 1152 to disengage it.

[0106] The first locking structure 1151 and the second locking structure 1152 can be conductive or non-conductive. For example, the conductive structure can be made of metal, and the non-conductive structure can be made of plastic.

[0107] In this embodiment, the locking assembly 1150 adopts a threaded connection, which makes the installation and disassembly of the locking assembly 1150 more convenient, thereby improving the installation and disassembly efficiency between the power distribution assembly 1140 and the enclosure 1110.

[0108] In some embodiments, as shown in Figures 6 and 7, either the first locking structure 1151 or the second locking structure 1152 is a stud structure, and the other is a nut structure, with the stud structure and the nut structure being threadedly connected.

[0109] In one possible implementation, referring to FIG7, the first locking structure 1151 is a stud structure, which is connected to the housing 1110. Specifically, the stud structure can be connected to the stiffening plate or beam inside the housing 1110. The second locking structure 1152 is a nut structure. Both the first guide plate and the second guide plate are provided with connecting holes. The stud structure passes through the connecting holes, and the nut structure abuts against the second guide plate. The stud structure and the nut structure are threadedly connected so that the first guide plate and the second guide plate are limited between the stud structure and the nut structure.

[0110] In another possible implementation, the first locking structure 1151 is a nut structure, which is connected to the housing 1110. The nut structure and the housing 1110 can be fixedly connected. The second locking structure 1152 is a stud structure, which is connected to the second guide piece. The stud structure can be movably connected to the second guide piece 1143. Both the first guide piece and the second guide piece can have connecting holes. The stud structure passes through the connecting hole and is threadedly connected to the nut structure, thereby limiting the first guide piece and the second guide piece between the stud structure and the nut structure.

[0111] In this embodiment, the locking assembly 1150 includes a stud structure and a nut structure. The threaded connection between the stud structure and the nut structure enables the limiting and fixing of the first guide piece and the second guide piece. The structure is simple, easy to manufacture, and convenient to install and disassemble, which helps to improve maintenance efficiency.

[0112] In some embodiments, as shown in Figures 5-7, the first locking structure 1151 is a stud structure, the second locking structure 1152 is a nut structure, and the locking assembly 1150 further includes an insulating seat connected to the housing 1110, with the stud structure connected to the insulating seat.

[0113] The insulating base is connected to the housing 1110. Specifically, the insulating base can be connected to the stiffening plate or beam inside the housing 1110. The insulating base is made of non-conductive material, ensuring insulation between the insulating base and the housing 1110. The stud structure is connected to the insulating base, thus ensuring insulation and non-conductivity between the stud structure and the housing 1110. The insulating base and the housing 1110 can be fixedly or detachably connected. The insulating base supports the stud structure. In addition, since the stud structure passes through the first guide plate, the insulating base also provides some support for the first guide plate. The stud structure and the insulating base can be fixedly or detachably connected.

[0114] Both the first and second guide plates have connecting holes, which can be through holes or threaded holes. The stud structure is inserted into the connecting holes on the first and second guide plates, and the nut structure is threadedly connected to the protruding end of the stud structure. This forms a limiting and fixing effect between the first and second guide plates, allowing the first guide plate to contact the second guide plate and thus achieve electrical connection.

[0115] In this embodiment, the insulating base can support the stud structure and the first conductive piece, and can insulate the stud structure and the first conductive piece from the housing, reducing the risk of short circuit between the stud structure and the housing.

[0116] In some embodiments, as shown in FIG3, the battery device 1100 further includes a guide assembly 1170, which is connected between the housing 1110 and the casing 1141.

[0117] The guide assembly 1170 is used to guide and position the power distribution assembly 1140 when it is inserted into the installation space 1114. The guide assembly 1170 can be disposed between the enclosure 1110 and the housing 1141. Specifically, the guide assembly 1170 can be disposed between the outer surface of the housing 1141 and the space wall (or cavity wall) of the installation space 1114. The guiding direction of the guide assembly 1170 is along the depth direction of the insertion interface 1115, so that when the housing 1141 enters and exits the installation space 1114, the guide structure can accurately guide the movement direction of the housing 1141 relative to the installation space 1114, thereby reducing the interference problem between the housing 1141 and the installation space 1114.

[0118] In this embodiment, by adding a guide structure between the housing 1110 and the shell 1141, the shell 1141 can move more smoothly in and out of the installation space 1114, reducing interference problems during the sliding process and improving assembly efficiency.

[0119] In some embodiments, referring to FIG3, the guide assembly 1170 includes a first guide structure 1171 connected to the housing 1141 and a second guide structure 1172 connected to the housing 1110. The first guide structure 1171 and the second guide structure 1172 are inserted into each other. The first guide structure 1171 is slidable relative to the second guide structure 1172 along a first direction X. The first direction X is parallel to the depth direction of the insertion interface 1115.

[0120] Specifically, the first guide structure 1171 and the second guide structure 1172 are interlocked, and the first guide structure 1171 and the second guide structure 1172 can slide relative to each other along the first direction X. It can be known that if either the first guide structure 1171 or the second guide structure 1172 is a protruding structure, then the other is a sliding groove structure. The extension direction of the sliding groove structure is along the first direction X, which is the depth direction of the insertion interface 1115, that is, the insertion direction of the housing 1141 relative to the installation space 1114.

[0121] The first guide structure 1171 can be connected to the outer surface of the housing 1141, and the second guide structure 1172 can be connected to the space wall (or cavity wall) of the mounting space 1114. For example, if the outer shape of the housing 1141 is a cube with four sides parallel to the first direction X and two end faces, the first guide structure 1171 can be disposed on any side of the cube. Correspondingly, the mounting space 1114 is also cubic in shape so that the mounting space 1114 matches and is inserted into the housing 1141. The second guide structure 1172 can be matched and disposed on the wall of the mounting space 1114 opposite to the first guide structure 1171.

[0122] In this embodiment, the guide component 1170 adopts a combination of the first guide structure 1171 and the second guide structure 1172 being inserted and slidably engaged. The structure is simple and easy to manufacture, and the configuration of the first guide structure 1171 and the second guide structure 1172 is also more flexible.

[0123] In some embodiments, as shown in FIG7, the battery device 1100 further includes a limiting component 1160, which is connected between the housing 1141 and the casing 1110. The limiting component 1160 is used to limit the movement of the housing 1141 relative to the casing 1110 along a second direction Y, which is perpendicular to the depth direction of the insertion interface 1115.

[0124] Specifically, the limiting component 1160 is used to limit the movement of the housing 1141 relative to the box 1110 in the second direction Y, which is perpendicular to the depth direction of the insertion interface 1115. For ease of description, the depth direction of the insertion interface 1115 is defined as the first direction X. Since the housing 1141 needs to be comfortably inserted into the installation space 1114, it is known that the outer diameter of the insertion interface 1115 should be larger than the outer diameter of the housing 1141. Therefore, it can be understood that a gap space is formed between the space wall of the installation space 1114 or the wall of the insertion interface 1115 and the outer surface of the housing 1141. Without the limiting component 1160, the housing 1141 will wobble at least along the second direction Y at the position of the insertion interface 1115.

[0125] Therefore, in this example, by providing a second limiting component 1160 between the housing 1141 and the box 1110, the second limiting component 1160 can restrict the housing 1141 from moving relative to the box 1110 along the second direction Y, thereby making it difficult for the housing 1141 to move relative to the box 1110 along the second direction Y, thus limiting the housing 1141.

[0126] In this embodiment, by providing a limiting component 1160 between the housing 1141 and the box 1110, the movement of the housing 1141 relative to the box 1110 along the second direction Y can be restricted, thereby reducing the shaking of the housing 1141 relative to the box 1110, protecting the housing 1141, and helping to reduce noise.

[0127] In some embodiments, as shown in FIG7, the limiting component 1160 includes a first limiting structure 1161 connected to the housing 1141 and a second limiting structure 1162 connected to the housing 1110, wherein the first limiting structure 1161 and the second limiting structure 1162 are inserted into each other along a first direction X.

[0128] Specifically, either the first limiting structure 1161 or the second limiting structure 1162 is a protruding structure, with the outward extension direction of the protruding structure along the first direction X. The other is a groove structure, with the groove depth direction of the groove structure also along the first direction X. When the housing 1141 is inserted into the installation space 1114 of the box 1110, the protruding structure is inserted into the groove structure, thereby restricting the movement of the housing 1141 along the direction perpendicular to the first direction X.

[0129] In this embodiment, when the housing 1141 is inserted into the installation space 1114, the first limiting structure 1161 and the second limiting structure 1162 limit the housing 1141 by means of insertion, thereby reducing the shaking of the housing 1141 relative to the box 1110, protecting the housing 1141, and helping to reduce noise.

[0130] In some embodiments, as shown in FIG5-7, the housing 1141 includes a housing body 11413 and a panel portion 11412. The housing body 11413 has an accommodating space 1113. An electronic system component 1144 is connected to the housing body 11413, and a locking component 1150 is connected between the housing body 11413 and the housing 1110. The panel portion 11412 is connected to the housing body 11413. The housing body 11413 is inserted into the mounting space 1114. The panel portion 11412 is exposed outside the mounting space 1114, and the edge of the panel portion 11412 extends to the outer periphery of the insertion interface 1115 and is connected to the surface of the housing body 11413.

[0131] Specifically, the shell body 11413 is the main body of the shell 1141. The shell body 11413 can be made of a plate structure. When the power distribution component 1140 is connected to the box 1110, the shell body 11413 is inserted into the installation space 1114. There will be a gap space between the shell body 11413 and the space wall of the installation space 1114 or the opening wall (or opening wall surface) of the plug-in interface 1115. This gap space allows the shell body 11413 to enter the installation space 1114 more smoothly, so as to reduce the interference between the side wall of the shell body 11413 and the space wall of the installation space 1114 or the opening wall of the plug-in interface 1115.

[0132] When the mounting space 1114 and the accommodating space 1113 are connected, the presence of the gap space will affect the sealing performance of the battery device 1100. Therefore, a panel 11412 is added. The panel 11412 is a plate-like structure exposed outside the shell body 11413 and the housing 1110. The panel 11412 is connected to the shell body 11413. After the shell body 11413 is inserted into the mounting space 1114, the panel 11412 forms the exposed surface of the shell 1141. The edge of the panel 11412 can extend to the outer periphery of the insertion interface 1115, so that the edge of the panel 11412 can cover the opening of the gap space, thereby shielding and sealing the gap space outside the housing 1110 and improving the sealing performance of the battery device 1100.

[0133] The panel 11412 is connected to the outer wall of the socket 1115 in the mounting space 1114. The panel 11412 and the wall can be connected by fastening components to achieve a detachable connection between the panel 11412 and the housing 1141 and the wall.

[0134] Additionally, the limiting component 1160 can be connected between the panel portion 11412 and the box wall. Specifically, the first limiting structure 1161 is connected to the side of the panel portion 11412 facing the box wall. The first limiting structure 1161 can be a protruding structure, which extends outward from the surface of the panel portion 11412 along the depth direction of the insertion interface 1115 (that is, the first direction X). The second limiting structure 1162 is connected to the box wall on the outer periphery of the insertion interface 1115 in the mounting space 1114. The second limiting structure 1162 can be a groove structure, with the protruding structure and the groove structure interlocking and cooperating.

[0135] Furthermore, the operating port 11415 is provided on the panel portion 11412. The operating port 11415 is a through hole provided on the panel portion 11412. When the panel portion 11412 is attached to or opposite to the shell wall of the shell body 11413, the operating port 11415 also needs to be provided on the shell wall opposite to or attached to the panel portion 11412. That is to say, the operating port 11415 penetrates the panel portion 11412 and the shell wall to extend into the accommodating space 1113.

[0136] In this embodiment, by adding a panel portion 11412, after the shell body 11413 in the housing 1141 is inserted into the mounting space 1114, the panel portion 11412 can seal the gap between the shell body 11413 and the mounting space 1114 at the insertion interface 1115 of the mounting space 1114, thereby improving the sealing performance of the battery device 1100.

[0137] In some embodiments, as shown in FIG7-9, the housing 1110 includes a frame 1117 and a cover 1116. The cover 1116 is detachably connected to the frame 1117 and together with the frame 1117 forms an accommodating space 1113. The cover 1116 is detachably connected to the frame 1117 and together with the frame 1117 forms an accommodating space 1113 and an installation space 1114. An insertion interface 1115 is provided on the frame 1117, and an opening 11414 is provided on the housing 1141 that communicates with the accommodating cavity 11411. The opening 11414 is disposed opposite to the cover 1116.

[0138] Specifically, the frame 1117 and the cover 1116 are connected to jointly enclose the accommodating space 1113 and the installation space 1114. Therefore, it can be understood that the frame 1117 may include a base plate and a circumferentially surrounding frame. The circumferential frame is arranged around the center of the box 1110 and connected to the base plate. The cover 1116 is located opposite the base plate. When the accommodating space 1113 and the installation space 1114 are two independent spaces, the frame 1117 also needs to be connected with beam structures or partition structures, so that the beam structures or partition structures isolate the accommodating space 1113 and the installation space 1114.

[0139] The insertion interface 1115 is formed on the frame body 1117. The frame body 1117 can be made of a plate structure. When the exterior of the frame body 1117 is cubic, the insertion interface 1115 can be formed on any one of the circumferential side plates (or circumferential side walls) of the frame body 1117.

[0140] For the power distribution assembly 1140, an opening 11414 is provided on the housing 1141. The opening 11414 is connected to or penetrates the receiving cavity 11411. The opening 11414 is used to allow the operator's hand or handheld tool to enter. When maintenance is required, the operator removes the cover 1116 from the frame 1117, thus exposing the installation space 1114. Since the housing 1141 is located within the installation space 1114, it is known that the housing 1141 is exposed. Furthermore, since the position of the housing 1141 relative to the cover 1116 forms an opening 11414, it is known that the opening 11414 is exposed. Since the electronic system component 1144 is installed within the accommodating cavity 11411, and the second guide 1143, locking assembly 1150, etc. are all located within the installation space 1114, the second guide 1143 and locking assembly 1150 can also be located within the accommodating cavity 11411. Thus, the electronic system component 1144, the second guide 1143, and the locking assembly 1150 are all in an exposed state, which facilitates the operator's installation and removal of the above components.

[0141] In this embodiment, the housing 1110 adopts a combination of a cover 1116 and a frame 1117. Opening the cover 1116 exposes the installation space 1114 and the accommodating cavity 11411 through the opening 11414. This allows the electronic system components 1144, the second conductor 1143, and the locking assembly 1150 to be exposed as much as possible in a position accessible to the operator. Thus, when the cover 1116 is opened, the power distribution component 1140 can be repaired, making maintenance more convenient.

[0142] In some embodiments, referring to Figures 8 and 9, the cover 1116 includes a first sub-cover portion 11161 and a second sub-cover portion 11162 connected to the first sub-cover portion 11161. Both the first sub-cover portion 11161 and the second sub-cover portion 11162 are detachably connected to the frame body 1117. The first sub-cover 1116 is disposed opposite to the battery cell assembly 1120, and the second sub-cover 1116 is disposed opposite to the opening 11414.

[0143] Specifically, the cover 1116 may include at least two parts, namely a first sub-cover 11161 and a second sub-cover 11162. The first sub-cover 11161 is connected to the frame 1117 to jointly enclose the accommodating space 1113, and the second sub-cover 11162 is connected to the frame 1117 to jointly enclose the installation space 1114. Therefore, it can be seen that the first sub-cover 1116 and the second sub-cover 1116 can be opened independently. Opening the first sub-cover 11161 exposes the accommodating space 1113 and the battery cell assembly 1120 located therein, allowing for the installation and removal of the battery cell assembly 1120. Opening the second sub-cover 11162 exposes the installation space 1114 and the power distribution assembly 1140, allowing for the installation, removal, or maintenance of the power distribution assembly 1140.

[0144] In this embodiment, the cover 1116 is designed such that the first sub-cover 11161 and the second sub-cover 11162 are independently detachably connected to the frame 1117. This allows the second sub-cover 1116 to be opened separately when the power distribution component 1140 needs to be repaired. This exposes the power distribution component 1140 and its internal electronic system components 1144, the second conductor 1143, and the locking component 1150, thus minimizing the impact on the environment of the battery cell assembly 1120 and protecting the battery cell assembly 1120.

[0145] In some embodiments, referring to Figures 8 and 9, the housing 1110 includes a first sub-housing portion 1118 and a second sub-housing portion 1119. The first sub-housing portion 1118 has an accommodating space 1113, and the second sub-housing portion 1110 has an installation space 1114. The housing 1141 and the first guide member 1130 are both connected to the second sub-housing portion 1110, and the second sub-housing portion 1119 is detachably connected to the first sub-housing portion 1118.

[0146] Specifically, for the housing 1110, the housing 1110 can be used to house the battery cell assembly 1120, and the housing 1110 can also be used to house the power distribution assembly 1140. The battery cell assembly 1120 and the power distribution assembly 1140 are respectively housed in different spaces of the housing 1110. Therefore, the housing 1110 can be designed as two detachable connected parts, which are the first sub-housing part 1118 and the second sub-housing part 1119. The housing space 1113 is opened in the first sub-housing part 1118, so that the first sub-housing part 1118 is used to house the battery cell assembly 1120; the mounting space 1114 is opened on the second sub-housing part 1110, so that the second sub-housing part 1119 is used to house the power distribution assembly 1140. When repairing the power distribution component 1140, the second sub-box 1110 can be removed from the first sub-box 1110 separately, thus avoiding the need to open the entire large box 1110, making the repair more convenient.

[0147] In this embodiment, the enclosure 1110 is connected by a combination of a first sub-enclosure 1118 and a second sub-enclosure 1119, so that when the power distribution component 1140 is being repaired, the second sub-enclosure 1119 can be disassembled separately, making the repair more convenient and labor-saving.
