Technical Field

[0001] This application relates to the field of battery technology, and in particular to a battery device and an electrical device having the same. Background Technology

[0002] In related technologies, the space inside a high-voltage distribution box is small while there are many electrical components. When multiple electrical components are assembled and arranged, the design clearance between the wiring harness and electrical components, as well as parts such as busbars, is small. The wiring harness is prone to contact with the busbars and wear, which increases the risk of wear on the wiring harness. This can lead to problems such as electrical short circuits, leakage, and system failures, thereby reducing the operational reliability and stability of the high-voltage distribution box. Utility Model Content

[0003] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a battery device in which the power distribution box can effectively reduce the risk of wire harness wear and make the operation of the power distribution box more stable and reliable.

[0004] This application also proposes an electrical device having the above-mentioned battery device.

[0005] A battery device according to a first aspect of this application includes: a power distribution box and battery cells, the power distribution box being used to distribute the power input to the battery cells and the power output from the battery cells, the power distribution box including: a housing body; a plurality of first electrical components and a bus, the plurality of first electrical components and the bus being disposed on one side of the housing body in a first direction, the plurality of first electrical components being electrically connected to the bus; and a wiring harness, the wiring harness being electrically connected to the first electrical components and / or the bus, and including a wiring harness body, the wiring harness body being disposed on the other side of the housing body in the first direction.

[0006] According to the battery device of this application, by setting up a power distribution box, the power distribution box includes a housing body, a busbar and multiple first electrical components are arranged on one side of the housing body in a first direction, and the wiring harness body is arranged on the other side of the housing body in the first direction. This greatly reduces the risk of contact wear between the wiring harness and the busbar, thereby making the operation of the power distribution box more stable and reliable. It can also significantly reduce the probability of interference between the wiring harness and the busbar and multiple first electrical components during arrangement. This makes it easier and more convenient to arrange the multiple first electrical components, the busbar and the wiring harness in the power distribution box, and the overall arrangement can be more compact. This results in a smaller overall volume of the power distribution box and less space occupation in the battery device, thereby significantly improving the overall space utilization and energy density of the battery device.

[0007] In some embodiments of this application, the housing body is provided with a clearance hole that penetrates the housing body along the first direction. The wiring harness also includes a first connecting branch line, one end of which is connected to the wiring harness body and the other end passes through the clearance hole and is connected to the busbar and / or the first electrical component.

[0008] In this embodiment, a clearance hole is provided on the housing body, which is simple in structure and facilitates the first connecting branch line to pass from one side of the housing body to the other side and connect to the busbar and / or the first electrical component. This can reduce the extension length of the first connecting branch line and make the connection of the wire harness to the busbar and the first electrical component more convenient.

[0009] In one embodiment of this application, there are multiple clearance holes, which are arranged at intervals on the shell body, and each clearance hole passes through one or more of the first connecting branches.

[0010] In this embodiment, the number of clearance holes is set to multiple, and the multiple clearance holes are arranged at intervals on the housing body. This allows multiple first connecting branches to pass through multiple clearance holes to easily connect with first electrical components at different positions on the housing body. This makes the routing and arrangement of the multiple first connecting branches more flexible and allows for a shorter extension length on one side of the housing body in the first direction. This makes the assembly of wire harnesses and busbars more convenient and can further reduce the risk of wire harness wear to a certain extent, making the operation of the distribution box more stable and reliable.

[0011] In some embodiments of this application, the shell body defines a receiving cavity, the shell body is provided with a plurality of partitions, the plurality of partitions are disposed in the receiving cavity and divide the receiving cavity into a plurality of first receiving slots, and a plurality of first electrical components are disposed in the plurality of first receiving slots.

[0012] In this embodiment, multiple partitions are used to divide the receiving cavity into multiple first receiving slots, allowing multiple first electrical components to be arranged in the multiple first receiving slots respectively. The structure is simple and can effectively separate the multiple first electrical components, blocking the electrical conduction path between adjacent first electrical components, meeting the electrical arrangement requirements such as creepage distance between first electrical components, and effectively reducing the probability of short circuits or damage to the first electrical components. At the same time, it allows the multiple first electrical components to be arranged more compactly, thereby reducing the overall space occupied by the distribution box, thus improving the overall space utilization and energy density of the battery device, and reducing the difficulty of arranging the matching box in the battery device, thereby reducing the design cost of the battery device to a certain extent.

[0013] In one embodiment of this application, the receiving cavity is open on the side opposite to the main body of the wiring harness in the first direction, and the power distribution box further includes a cover that covers the main body of the housing and seals the open side of the receiving cavity.

[0014] In this embodiment, the receiving cavity is set to be open on one side of the back-to-back cable bundle body in the first direction, which facilitates the assembly of multiple first electrical components and busbars onto the housing body. The distribution box is provided with a cover that covers the housing body and seals the open side of the receiving cavity, so that the multiple first electrical components, busbars and first connecting branches can be well sealed and protected, and the first electrical components and busbars can be in a stable operating environment, thereby making the operation of the distribution box more stable and reliable.

[0015] In some embodiments of this application, the plurality of first electrical components include: relays, fuses, current sensors and / or shunts.

[0016] In this embodiment, multiple first electrical components include relays, fuses, current sensors, and / or shunts, which can meet the operational needs of the distribution box and enable it to operate efficiently and stably.

[0017] In some embodiments of this application, the power distribution box further includes a second electrical component, which is disposed on the other side of the housing body in the first direction, and the wiring harness further includes a second connecting branch line, which is connected between the wiring harness body and the second electrical component.

[0018] In this embodiment, the second electrical component is arranged on the other side of the housing body in the first direction. The wiring harness is connected to the second electrical component by a second connecting branch. The structure is simple and the arrangement is reasonable. Compared with arranging the second electrical component on the side of the housing body with the busbar, it can eliminate the need for the second connecting branch to go around to the other side of the housing body. It also reduces the obstruction caused by the arrangement of the second electrical component to the arrangement of the first electrical component and the busbar. It reduces the probability of increased arrangement space due to installation requirements or electrical clearance requirements when arranging the busbar and the second connecting branch. It makes the connection between the second electrical component and the wiring harness more convenient and easier. It allows the arrangement of the second connecting branch and the second electrical component in the distribution box to be more compact. It also allows the busbar, the first electrical component, the second electrical component, and the wiring harness to be arranged more compactly. As a result, the overall volume of the distribution box is smaller, and the space occupied by the distribution box in the battery device is smaller. This greatly improves the overall space utilization and energy density of the battery device.

[0019] In one embodiment of this application, the shell body is provided with a second receiving groove on the other side of the first direction, and the second electrical component is disposed in the second receiving groove.

[0020] In this embodiment, the second electrical component is disposed in the second receiving groove. The second receiving groove can effectively accommodate and protect the second electrical component, allowing it to operate in a stable environment and thus enabling it to operate more stably. At the same time, it allows the second electrical component to be quickly positioned and assembled onto the housing body via the second receiving groove, making the assembly of the distribution box more efficient.

[0021] In some examples of this application, there are multiple second electrical components and multiple second receiving slots, with each of the multiple second receiving slots arranged in a one-to-one correspondence with a multiple of the second electrical components.

[0022] In this embodiment, the number of second electrical components is set to multiple, which can meet the operational needs of the power distribution box. Multiple second receiving slots are arranged one-to-one with multiple second electrical components, so that multiple second electrical components can be stably separated and well protected, making the operation of the power distribution box more stable, and making it easier and more convenient to assemble multiple second electrical components with the shell body, making the assembly of the power distribution box more efficient.

[0023] In one example of this application, the plurality of second electrical components include: a precharge resistor and a precharge relay.

[0024] In this embodiment, multiple second electrical components include pre-charge resistors and pre-charge relays, which can meet the operational needs of the power distribution box during operation, enabling the power distribution box to operate stably and reliably.

[0025] In one example of this application, the shell body is configured to be recessed on the side facing the shell body in the first direction to form the second receiving groove.

[0026] In this embodiment, the second receiving groove is formed by the recess of the shell body along the first direction toward the shell body. The structure is simple and can make the overall size of the shell body smaller in the first direction. This allows the arrangement of the first electrical component, the second electrical component and the wiring harness in the first direction to be more compact, thereby reducing the space occupied by the power distribution box in the first direction. This can improve the space utilization and energy density of the battery device to a certain extent.

[0027] In some embodiments of this application, the wire harness body and the shell body are fixed together by cable ties.

[0028] In this embodiment, the main body of the wire harness and the main body of the shell are fixed together with cable ties. The structure is simple and the fixation is reliable, so that the main body of the wire harness can be stably fixed to the main body of the shell.

[0029] In some embodiments of this application, the busbar is detachably connected to the housing body.

[0030] In this embodiment, the busbar is detachably connected to the housing body, which is simple in structure and allows the busbar to be stably and reliably fixed to the housing body. It also facilitates the installation and removal of the busbar, making the power distribution box easier to assemble and disassemble.

[0031] The electrical device according to the second aspect of this application includes the battery device according to the first aspect of this application.

[0032] According to the power supply device of this application, by setting up the battery device of the first aspect, the battery device is provided with a power distribution box, the power distribution box is provided with a housing body, the busbar and a plurality of first electrical components are arranged on one side of the housing body in a first direction, and the main body of the wiring harness is arranged on the other side of the housing body in the first direction, which greatly reduces the risk of contact wear between the wiring harness and the busbar, thereby making the operation of the power distribution box more stable and reliable, and can effectively reduce the probability of interference between the wiring harness and the busbar and the plurality of first electrical components during arrangement, making it easier and more convenient to arrange the plurality of first electrical components, the busbar and the wiring harness in the power distribution box, and the overall arrangement can be more compact, making the overall volume of the power distribution box smaller and occupying less space in the battery device, thereby greatly improving the overall space utilization and energy density of the battery device.

[0059] Currently, judging from market trends, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of power battery applications, market demand is also constantly increasing.

[0060] In battery devices, the power distribution box is part of the battery management system, playing a role in distributing, protecting, and managing the battery's power. The power distribution box contains numerous electrical components, such as relays, fuses, and pre-charge resistors, to meet its operational needs. When the power distribution box is placed inside the battery casing, its overall size is relatively small to meet the requirements of battery energy density and space utilization. The box requires busbars to connect to some electrical components, and wiring harnesses to connect to the busbars or other electrical components to transmit power and signals. The limited space makes it easy for wiring harnesses and busbars to come into contact and rub against each other, leading to wear and tear. This increases the risk of short circuits and malfunctions during operation, resulting in poor operational stability and reliability of the power distribution box.

[0061] Based on the above considerations, in order to reduce the risk of wire harness wear in the distribution box and improve the operational stability and reliability of the distribution box, the applicant designed a distribution box that separates the wire harness and the busbar through the housing, which greatly reduces the probability of the wire harness coming into contact with the busbar, thereby effectively reducing the risk of wire harness wear and making the distribution box more stable and reliable during operation.

[0062] The battery device disclosed in this application may include a power distribution box and one or more battery cell assemblies. The battery cell assembly is used to provide voltage and capacity. The battery cell assembly may include multiple battery cells, which are connected in series, parallel or mixed connection through a busbar. In some embodiments, the battery cell assembly is usually formed by arranging multiple battery cells.

[0063] As an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells together to form an independent module. As another example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0064] In some embodiments, the battery device may be a battery pack, which includes a housing and one or more individual battery cell assemblies housed within the housing.

[0065] As an example, the battery cell assembly can be a battery module, which can be housed in a housing by fixing the battery module in the housing.

[0066] As an example, battery cell assemblies can also be housed in a housing by directly fixing multiple battery cells to the housing.

[0067] As an example, the enclosure may include a first enclosure and a second enclosure. The first enclosure and the second enclosure are fastened together to form a closed space inside the enclosure to house the individual battery cells. Here, "closed" refers to covering or closing, and can be either sealed or unsealed. The first enclosure may be a top cover or a bottom plate.

[0068] As an example, the enclosure may include a top cover, a frame, and a bottom plate. The top cover and bottom plate are connected to the frame, creating an enclosed space inside the enclosure to house the individual battery cells.

[0069] In some embodiments, the housing may be part of the vehicle's chassis structure. For example, a portion of the housing may be at least a part of the vehicle's floor, or a portion of the housing may be at least a part of the vehicle's crossbeams and longitudinal beams.

[0070] Battery devices can be used as power sources for electrical devices, or in various energy storage systems that use battery devices as energy storage elements. Electrical devices can be, but are not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, etc. Electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0071] For example, refer to Figure 1 As shown, Figure 1 This is a schematic diagram of an electrical device according to an embodiment of this application. When the electrical device is a vehicle, the vehicle 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 is installed inside the vehicle, and the battery device can be located at the bottom, front, or rear of the vehicle. The battery device can be used to power the vehicle; for example, the battery device can serve as the vehicle's operating power source. The vehicle may also include a controller and a motor. The controller is used to control the battery device to supply power to the motor, for example, for the vehicle's starting, navigation, and operating power needs.

[0072] In some embodiments of this application, the battery device can not only serve as the operating power source for the vehicle, but also as the driving power source for the vehicle, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle.

[0073] The following is for reference. Figures 2-6 A battery device according to an embodiment of the first aspect of this application is described. Figure 2 This is a schematic diagram of a battery device according to an embodiment of this application; Figure 3 This is a schematic diagram of a power distribution box according to an embodiment of this application; Figure 4 This is a schematic diagram of a power distribution box according to an embodiment of this application from another angle; Figure 5 This is an exploded view of a power distribution box according to an embodiment of this application; Figure 6 This is a schematic diagram of the shell body according to an embodiment of this application.

[0074] like Figures 2-6As shown, the battery device 100 according to the first aspect embodiment of this application includes: a power distribution box 10 and a battery cell. The power distribution box 10 is used to distribute the power input to the battery cell and the power output from the battery cell. The power distribution box 10 includes: a housing body 11, a plurality of first electrical components and a busbar 12 and a wiring harness 15.

[0075] In this embodiment, a power distribution box 10 is arranged in the battery device 100. The power distribution box 10 can distribute the power flowing to various external devices and control the current flow when the battery device 100 transmits power to the outside, so as to meet the power supply needs of the battery device 100 to the external devices. The power distribution box 10 can also balance and distribute the power among the battery cells in the battery device 100 to extend the overall service life of the battery device 100. When the battery device 100 is charging, the power distribution box 10 can reasonably distribute the power input to the battery cells so that the current can be stably input into each battery cell, thereby enabling the battery device 100 to operate stably and reliably.

[0076] In this embodiment, the battery cell can be a secondary battery. A secondary battery is a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged. For example, the battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc. This embodiment does not limit the specific type of battery cell.

[0077] Specifically, multiple first electrical components and busbars 12 are all disposed on the housing body 11 in the first direction (e.g., Figure 3 On one side of the z-direction shown, multiple first electrical components are electrically connected to busbar 12; wire harness 15 is electrically connected to the first electrical components and / or busbar 12, and includes wire harness body 151, which is disposed on the other side of housing body 11 in the first direction.

[0078] In this embodiment, the power distribution box 10 is provided with a housing body 11. The housing body 11 can be a plastic part or a metal part with an insulating layer, etc. The housing body 11 can extend in a plane perpendicular to a first direction. The first direction can be the thickness direction of the housing body 11, so as to meet the needs of the installation and arrangement of electrical components.

[0079] Multiple first electrical components and busbars 12 are disposed on one side of the housing body 11 in the first direction. For example, multiple first electrical components can be connected by busbars 12, and busbars 12 are then assembled and fixed to the housing body 11, so that multiple first electrical components are assembled on the housing body 11. The number of busbars 12 can be multiple, and multiple first electrical components are connected by multiple busbars 12. Busbars 12 can be copper busbars.

[0080] In this embodiment, the wiring harness 15 is electrically connected to the first electrical component and / or the bus 12. For example, the wiring harness 15 can be electrically connected to the first electrical component, or it can be electrically connected to the bus 12. The wiring harness 15 can also be electrically connected to the first electrical component and the bus 12 as needed. The connection between the wiring harness 15 and the first electrical component and the bus 12 can be flexibly arranged as needed.

[0081] In this embodiment, the wiring harness 15 includes a wiring harness body 151. For example, the wiring harness body 151 can be composed of a sheath and multiple wires. The sheath wraps around the multiple wires to form the wiring harness body 151. The multiple wires can extend out of the wiring harness body 151 to flexibly connect with the corresponding first electrical component or busbar 12. The ends of the wires can also be provided with plug terminals to cooperate with the socket structure on the first electrical component to realize plug connection. The wiring harness body 151 refers to the main part of the wiring harness 15. When the wiring harness 15 is arranged in the distribution box 10, the wiring harness 15 is arranged on the other side of the housing body 11 in the first direction and then connected to multiple first electrical components through the extended wires.

[0082] In this embodiment, the first electrical component and the busbar 12 are arranged on the same side of the housing body 11 in the first direction, which facilitates the connection and arrangement of multiple first electrical components and the busbar 12, so that the busbar 12 can be easily connected to multiple first electrical components. The busbar 12 has a relatively robust structure, so that multiple first electrical components can be stably installed on the housing body 11 through the busbar 12.

[0083] In this embodiment, the busbar 12 is arranged on one side of the housing body 11 in the first direction, and the wire harness body 151 of the wiring harness 15 is arranged on the other side of the housing body 11 in the first direction. This ensures that the busbar 12 and the wire harness body 151 of the wiring harness 15 are stably and reliably separated by the housing body 11. Compared to arranging the wiring harness 15 and the busbar 12 on the same side of the housing body 11 in the first direction, this greatly reduces the probability of contact and rubbing between the wiring harness 15 and the busbar 12, significantly reducing the risk of wear and tear on the wiring harness 15. This makes the operation of the distribution box 10 more stable and reliable. At the same time, it effectively reduces the risk of contact and rubbing between the wire harness body 151 and the busbar 12 on the other side of the housing body 11 in the first direction. When arranged on the same side, the interference with the busbar 12 and multiple first electrical components allows for a larger space for the arrangement of the wiring harness 15, the busbar 12, and the first electrical components. This makes the wiring of the wiring harness 15 easier and more convenient, and makes the arrangement of the first electrical components and the busbar 12 more convenient and the overall structure more compact. This makes the assembly of the distribution box 10 easier and, to a certain extent, allows the overall volume of the distribution box 10 to be smaller. This results in a smaller space occupied by the distribution box 10 in the battery device 100, thereby improving the overall space utilization and energy density of the battery device 100.

[0084] According to the battery device 100 of the present application embodiment, by setting up a power distribution box 10 and battery cells, the power distribution box 10 is provided with a housing body 11, a busbar 12 and a plurality of first electrical components are arranged on one side of the housing body 11 in a first direction, and the wiring harness body 151 of the wiring harness 15 is arranged on the other side of the housing body 11 in the first direction, which greatly reduces the risk of contact wear between the wiring harness 15 and the busbar 12, thereby making the operation of the power distribution box 10 more stable and reliable, and can effectively reduce the probability of interference between the wiring harness 15 and the busbar 12 and the plurality of first electrical components during arrangement, making it easier and more convenient to arrange the plurality of first electrical components, the busbar 12 and the wiring harness 15 in the power distribution box 10, and the overall arrangement can be more compact, making the overall volume of the power distribution box 10 smaller and occupying less space in the battery device 100, thereby greatly improving the overall space utilization and energy density of the battery device 100.

[0085] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the housing body 11 may be provided with a clearance hole 112, which penetrates the housing body 11 along a first direction. The wiring harness 15 also includes a first connecting branch line 152, one end of which is connected to the wiring harness body 151, and the other end passes through the clearance hole 112 and is connected to the busbar 12 and / or the first electrical component.

[0086] In this embodiment, the shell body 11 is provided with a clearance hole 112 penetrating the shell body 11 in a first direction. One end of the first connecting branch line 152 of the wire harness 15 is connected to the wire harness body 151 and the other end passes through the clearance hole 112. The first connecting branch line 152 can be formed by one, two, three, or other wires extending from the wire harness body 151. There can be multiple first connecting branch lines 152. Multiple first connecting branch lines 152 can be connected to corresponding first electrical components or busbars 12 as needed. For example, a first electrical component can be connected to one or more first connecting branch lines 152 as needed. The first connecting branch line 152 can be connected to a preset connection position on the busbar 12 to meet the connection requirements. For example, the clearance hole 112 can be a round hole, an oblong hole, a rectangular hole, an irregularly shaped hole, etc.

[0087] For example, when the main body 151 of the wiring harness is connected to the first connecting branch line 152 at the edge of the housing body 11, the first connecting branch line 152 can also extend directly from the edge of the housing body 11 to one side of the housing body 11 in the first direction to connect with the busbar 12 or the first electrical component. The first connecting branch line 152 can be flexibly adjusted according to the specific arrangement position to facilitate connection with the first electrical component or the busbar 12 so that it has a shorter extension length on one side of the housing body 11 in the first direction.

[0088] In this embodiment, a clearance hole 112 is provided on the housing body 11. The structure is simple and facilitates the first connecting branch line 152 to pass from one side of the housing body 11 to the other side and connect to the busbar 12 and / or the first electrical component. This can reduce the extension length of the first connecting branch line 152 and make the connection between the wire harness 15 and the busbar 12 and the first electrical component more convenient.

[0089] For example, refer to Figure 3 As shown, both the first electrical component and the busbar 12 are provided with electrical connection portions. On the plane perpendicular to the first direction, the clearance hole 112 can be arranged close to the electrical connection portion. This reduces the distance between the first connecting branch line 152 and the electrical connection portion after it extends through the clearance hole 112 to the side of the housing body 11 in the first direction. This reduces the length of the first connecting branch line 152 on the side of the housing body 11 in the first direction, further reducing the probability of the wiring harness 15 rubbing against the busbar 12, thereby further reducing the risk of wear on the wiring harness 15 and making the operation of the distribution box 10 more stable and reliable.

[0090] In one embodiment of this application, reference is made to Figure 3 and Figure 4 As shown, there can be multiple clearance holes 112, and multiple clearance holes 112 are arranged at intervals on the shell body 11. Each clearance hole 112 is provided with one or more first connecting branches 152.

[0091] In this embodiment, the number of clearance holes 112 is set to multiple, such as two, three, four, five, six, etc. The multiple clearance holes 112 are arranged at intervals on the shell body 11. Each clearance hole 112 has one or more first connecting branch lines 152. For example, one first connecting branch line 152 can be passed through one clearance hole 112, and two, three or four first connecting branch lines 152 can be passed through another clearance hole 112. When the distribution box 10 is assembled, the first connecting branch line 152 can pass through the closer clearance hole 112 to one side of the shell body 11 to connect with the busbar 12 and the first electrical component, according to the arrangement position of the corresponding connected busbar 12 or the electrical connection part of the first electrical component on the shell body 11.

[0092] In this embodiment, the number of clearance holes 112 is set to multiple, and the multiple clearance holes 112 are arranged at intervals on the housing body 11. This allows multiple first connecting branches 152 to pass through multiple clearance holes 112 to easily connect with first electrical components at different positions on the housing body 11. This makes the routing and arrangement of the multiple first connecting branches 152 more flexible and allows them to have a shorter extension length on one side of the housing body 11 in the first direction. This makes the assembly of the wire harness 15 and busbar 12 more convenient, and to a certain extent, it can further reduce the risk of wear of the wire harness 15, making the operation of the distribution box 10 more stable and reliable.

[0093] In some embodiments of this application, reference is made to Figure 3 and Figure 6 As shown, the shell body 11 defines a receiving cavity 1101. The shell body 11 may be provided with multiple partitions 111. The multiple partitions 111 are provided in the receiving cavity 1101 and divide the receiving cavity 1101 into multiple first receiving slots 11011. Multiple first electrical components are provided in the multiple first receiving slots 11011.

[0094] In this embodiment, the shell body 11 defines a receiving cavity 1101, and multiple partitions 111 divide the receiving cavity 1101 into multiple first receiving slots 11011. Multiple first electrical components are disposed in multiple first receiving slots 11011. The size and dimensions of different first receiving slots 11011 can match the size and dimensions of the corresponding first electrical components. The first receiving slots 11011 can be arranged one-to-one with the first electrical components.

[0095] In this embodiment, multiple partitions 111 are used to divide the receiving cavity 1101 into multiple first receiving slots 11011, so that multiple first electrical components can be arranged in multiple first receiving slots 11011 respectively. The structure is simple and can play a good role in separating multiple first electrical components, blocking the electrical conduction path between adjacent first electrical components, meeting the electrical layout requirements such as creepage distance between first electrical components, and effectively reducing the probability of short circuits or damage to first electrical components. At the same time, it allows multiple first electrical components to be arranged more compactly, thereby reducing the overall space occupied by the distribution box 10, thus improving the overall space utilization and energy density in the battery device 100, and reducing the difficulty of arranging the matching box in the battery device 100, thereby reducing the design cost of the battery device 100 to a certain extent.

[0096] In one embodiment of this application, reference is made to Figure 5 As shown, the receiving cavity 1101 is open on one side of the back of the cable bundle body 151 in the first direction. The power distribution box 10 may also include a cover, which covers the shell body 11 and seals the open side of the receiving cavity 1101.

[0097] In this embodiment, the receiving cavity 1101 is open on one side of the back-to-back cable main body 151 in the first direction. During the assembly of the distribution box 10, the busbar 12 and multiple first electrical components can be assembled onto the housing body 11 from the open side of the receiving cavity 1101. The multiple first electrical components are respectively arranged in the corresponding first receiving slots 11011 from the open side of the receiving cavity 1101. The distribution box 10 is provided with a cover, which covers the housing body 11 and seals the open side of the receiving cavity 1101. The cover and the housing body 11 can be fixedly connected by fasteners, adhesives, etc.

[0098] In this embodiment, the receiving cavity 1101 is set to be open on one side of the back-to-back cable bundle body 151 in the first direction, which facilitates the assembly of multiple first electrical components and busbars 12 onto the housing body 11. The distribution box 10 is provided with a cover that covers the housing body 11 and seals the open side of the receiving cavity 1101, so that multiple first electrical components, busbars 12 and first connecting branch lines 152 can be well sealed and protected, so that the first electrical components and busbars 12 can be in a stable operating environment, thereby making the operation of the distribution box 10 more stable and reliable.

[0099] In some embodiments of this application, such as Figure 3 and Figure 5 As shown, the plurality of first electrical components may include: relay 131, fuse 132, current sensor 133 and / or shunt 134.

[0100] In this embodiment, multiple first electrical components include a relay 131, a fuse 132, a current sensor 133, and / or a shunt 134. The relay 131 is an electrical control device with the function of controlling high voltage with low voltage. It can be used to control the opening and closing of a circuit or to control a high voltage and high current circuit by receiving a low voltage and low current signal. The number of relays 131 can be arranged as needed. For example, the number of relays 131 can be two, three, four, etc.

[0101] The fuse 132 is used to quickly disconnect the circuit in case of overload or short circuit, reducing the probability of damage to other primary electrical components and fire. For example, the fuse 132 can be an exploding fuse. The current sensor 133 is used to monitor the current in the circuit and provide timely feedback to the monitoring or control system of the battery device 100 in case of overload or other conditions. The shunt 134 can be used for accurate measurement of the current in the circuit.

[0102] In this embodiment, multiple first electrical components include a relay 131, a fuse 132, a current sensor 133, and / or a shunt 134, which can meet the operational needs of the distribution box 10 and enable the distribution box 10 to operate efficiently and stably.

[0103] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the distribution box 10 may also include a second electrical component, which is located on the other side of the housing body 11 in the first direction. The wiring harness 15 may also include a second connecting branch line 153, which is connected between the wiring harness body 151 and the second electrical component.

[0104] In this embodiment, the distribution box 10 also includes a second electrical component. The second electrical component is arranged on the other side of the housing body 11 in the first direction. The number of the second electrical components can be one or more. When there are multiple second electrical components, they can be arranged at intervals on the housing body 11. The second electrical components are not connected to the busbar 12. The wiring harness 15 is provided with a second connecting branch line 153 to connect to the second electrical component. The second connecting branch line 153 and the wiring harness body 151 are located on the same side of the housing body 11 in the first direction. The second connecting branch line 153 can be fixed to the housing body 11 by cable ties 16 or the like. When the distribution box 10 is assembled, after the second electrical component is arranged on the housing body 11, it only needs to be connected to the wiring harness 15 through the second connecting branch line 153. The number of wires in the second connecting branch line 153 can be flexibly set according to the connection requirements of the second electrical component.

[0105] In this embodiment, the second electrical component is arranged on the other side of the housing body 11 in the first direction. The wiring harness 15 is provided with a second connecting branch 153 connected to the second electrical component. The structure is simple and the arrangement is reasonable. Compared with arranging the second electrical component on the side of the housing body 11 with the busbar 12, it can eliminate the need for the second connecting branch 153 to be routed to the other side of the housing body 11, and reduce the obstruction caused by the arrangement of the second electrical component to the arrangement of the first electrical component and the busbar 12. It also reduces the need for installation requirements or... The increased probability of increased layout space due to the need for electrical clearance makes it easier to connect the second electrical component to the wiring harness 15, and allows for a more compact arrangement of the second connecting branch line 153 and the second electrical component within the distribution box 10. This makes the busbar 12, the first electrical component, the second electrical component, and the wiring harness 15 more compact in their arrangement, thereby reducing the overall size of the distribution box 10 and the space occupied by the distribution box 10 in the battery device 100. As a result, the overall space utilization and energy density of the battery device 100 are greatly improved.

[0106] In one embodiment of this application, reference is made to Figure 4 and Figure 5 As shown, the shell body 11 may be provided with a second receiving groove 1102 on the other side of the first direction, and the second electrical component is provided in the second receiving groove 1102.

[0107] In this embodiment, the shell body 11 is provided with a second receiving groove 1102 on the other side of the first direction. The second electrical component is disposed in the second receiving groove 1102. The size and shape of the second receiving groove 1102 can match the size and shape of the correspondingly arranged second electrical component. The second electrical component can be fixed to the bottom wall of the second receiving groove 1102 by fasteners.

[0108] In this embodiment, the second electrical component is disposed in the second receiving groove 1102. The second receiving groove 1102 can effectively accommodate and protect the second electrical component, allowing it to operate in a stable environment and thus enabling it to operate more stably. At the same time, it allows the second electrical component to be quickly positioned and assembled onto the housing body 11 via the second receiving groove 1102 during assembly, making the assembly of the power distribution box 10 more efficient.

[0109] In some examples of this application, references Figure 4 As shown, there can be multiple second electrical components and multiple second receiving slots 1102, with each of the multiple second receiving slots 1102 arranged in a one-to-one correspondence with a multiple second electrical component.

[0110] In this embodiment, the number of second electrical components is set to multiple, and multiple second receiving slots 1102 are arranged one-to-one with multiple second electrical components. For example, when the number of second electrical components is two, three, four, five, etc., the number of second receiving slots 1102 is set to two, three, four, five, etc., respectively. Multiple second receiving slots 1102 can be flexibly arranged on the shell body 11 as needed.

[0111] In this embodiment, the number of second electrical components is set to be multiple, which can meet the operational needs of the power distribution box 10. Multiple second receiving slots 1102 are arranged one-to-one with multiple second electrical components, so that multiple second electrical components can be stably separated and the multiple second electrical components can be well protected, making the operation of the power distribution box 10 more stable, and making it easier and more convenient to assemble multiple second electrical components with the shell body 11, making the assembly of the power distribution box 10 more efficient.

[0112] In one example of this application, such as Figure 4 and Figure 5 As shown, the plurality of second electrical components may include: a pre-charge resistor 141 and a pre-charge relay 142.

[0113] In this embodiment, multiple second electrical components include a pre-charge resistor 141 and a pre-charge relay 142. The pre-charge resistor 141 is used to limit the current in the circuit when the battery device 100 is first connected to an electrical system such as a load, so as to reduce the impact of a large instantaneous circuit on the electrical components in the circuit and improve the reliability of the electrical system. The pre-charge relay 142 is used to cooperate with the pre-charge resistor 141 to adjust the circuit flow through the pre-charge resistor 141 to perform pre-charge operation and to disconnect the circuit of the pre-charge resistor 141 after pre-charge is completed.

[0114] In this embodiment, multiple second electrical components include a pre-charge resistor 141 and a pre-charge relay 142, which can meet the operational needs of the power distribution box 10 during operation, enabling the power distribution box 10 to operate stably and reliably.

[0115] In one example of this application, reference is made to Figure 5 As shown, the shell body 11 can be configured to be recessed on one side of the shell body 11 in a first direction to form a second receiving groove 1102.

[0116] In this embodiment, the shell body 11 is configured to be recessed on one side of the shell body 11 in the first direction to form a second receiving groove 1102. In the first direction, the second receiving groove 1102 and the first receiving groove 11011 can be in the same extension range. On the projection plane perpendicular to the first direction, the second receiving groove 1102 can be staggered from the first receiving groove 11011.

[0117] In this embodiment, the second receiving groove 1102 is formed by the recess of the shell body 11 along the first direction toward the shell body 11. The structure is simple and can make the overall size of the shell body 11 smaller in the first direction. This allows the arrangement of the first electrical component, the second electrical component and the wiring harness 15 in the first direction to be more compact, thereby reducing the space occupied by the power distribution box 10 in the first direction. This can improve the space utilization and energy density of the battery device 100 to a certain extent.

[0118] In some embodiments of this application, such as Figure 4 As shown, the main body 151 of the wire harness and the main body 11 of the housing can be fixed by cable ties 16.

[0119] In this embodiment, the main body 151 of the wire harness and the main body 11 of the shell are fixed by cable ties 16. There can be multiple cable ties 16, which can be arranged at intervals along the extension direction of the main body 151 of the wire harness. The main body 11 of the shell can be provided with a fixing part for fixing the cable ties 16, and the fixing part has through holes for the cable ties 16 to be inserted.

[0120] In this embodiment, the main body 151 of the wire harness and the main body 11 of the shell are fixed together by cable ties 16. The structure is simple and the fixation is reliable, so that the main body 151 of the wire harness can be stably fixed on the main body 11 of the shell.

[0121] In some embodiments of this application, the busbar 12 is detachably connected to the housing body 11.

[0122] In this embodiment, the busbar 12 and the housing body 11 are detachably connected. For example, the busbar 12 and the housing body 11 can be fastened together by fasteners. The busbar 12 can be provided with an assembly hole, and the housing body 11 can be provided with a threaded hole. After the busbar 12 and the first electrical component are assembled onto the housing body 11, the fasteners can pass through the assembly hole and the threaded hole and be threaded together, thereby fixing the busbar 12 onto the housing body 11.

[0123] In this embodiment, the busbar 12 is detachably connected to the housing body 11, which is simple in structure and allows the busbar 12 to be stably and reliably fixed on the housing body 11. It also facilitates the installation and removal of the busbar 12, making the power distribution box 10 easier to assemble and disassemble.

[0124] The following is for reference. Figures 1-6 Describes an electrical device 1000 according to an embodiment of the second aspect of this application.

[0125] like Figures 1-6 As shown, the power-consuming device 1000 according to an embodiment of this application includes the battery device 100 according to the first aspect of this application.

[0126] Other configurations and operations of the electrical device 1000 according to the embodiments of this application are known to those skilled in the art and will not be described in detail here.

[0127] According to the embodiment of this application, the power device 1000, by setting up the battery device 100 of the first aspect embodiment described above, includes a power distribution box 10 in the battery device 100. The power distribution box 10 has a housing body 11. The busbar 12 and a plurality of first electrical components are arranged on one side of the housing body 11 in a first direction, and the wire harness body 151 of the wire harness 15 is arranged on the other side of the housing body 11 in the first direction. This greatly reduces the risk of contact wear between the wire harness 15 and the busbar 12, thereby making the operation of the power distribution box 10 more stable and reliable. It can also effectively reduce the probability of interference between the wire harness 15 and the busbar 12 and the plurality of first electrical components during arrangement. This makes it easier and more convenient to arrange the plurality of first electrical components, the busbar 12, and the wire harness 15 in the power distribution box 10, and the overall arrangement can be more compact. This makes the overall volume of the power distribution box 10 smaller and the space occupied in the battery device 100 smaller, thereby greatly improving the overall space utilization and energy density of the battery device 100.

[0128] The following will refer to Figures 1-6 This application describes an electrical device 1000 according to a specific embodiment.

[0129] like Figures 1-6As shown, the electrical device 1000 is a vehicle. The electrical device 1000 includes a motor 200, a controller 300, and a battery device 100. The controller 300 is used to control the battery device 100 to supply power to the motor 200. The battery device 100 includes a power distribution box 10, which is a high-voltage power distribution box 10.

[0130] The distribution box 10 includes a cover, a housing body 11, a first electrical component, a busbar 12, a second electrical component, and a wiring harness 15. The housing body 11 has a receiving cavity 1101 formed on one side in a first direction. The receiving cavity 1101 is open in the first direction and contains multiple partitions 111 that divide the receiving cavity 1101 into multiple first receiving slots 11011. The cover is placed on the side of the housing body 11 with the receiving cavity 1101. On the other side of the housing body 11 in the first direction, two second receiving slots 1102 are recessed along the first direction. The busbar 12 is a copper busbar. The housing body 11 and the cover are made of plastic.

[0131] The number of first electrical components is multiple, including four relays 131, two fuses 132, a current sensor 133, and a shunt 134. The four relays 131 are high-voltage relays, the two fuses 132 are a tubular fuse and an explosive fuse, and the current sensor 133 is a Hall current sensor. The multiple first electrical components are connected by a busbar 12, which is fastened to the housing body 11. The multiple first electrical components are respectively arranged in multiple first receiving slots 11011, and the four relays 131 are respectively arranged in four first receiving slots 11011. The number of second electrical components is two, namely a pre-charge resistor 141 and a pre-charge relay 142, which are respectively arranged in a second receiving cavity 1101.

[0132] Three clearance holes 112 are provided on the shell body 11. The clearance holes 112 can be round holes with a diameter of 30mm, so that the assembly personnel can pass the first connecting branch 152 through the clearance holes 112. The clearance hole 112 penetrates the shell body 11 along the first direction. The wiring harness 15 includes a wiring harness body 151, a first connecting branch line 152, and a second connecting branch line 153. The first connecting branch line 152 and the second connecting branch line 153 are formed by wires extending from the wiring harness body 151. The wiring harness body 151 is arranged on the other side of the shell body 11 in the first direction. The wiring harness body 151 is fixed to the shell body 11 by cable ties 16. There are multiple first connecting branch lines 152. The multiple first connecting branch lines 152 pass through the three clearance holes 112 into the receiving cavity 1101 and are connected to the corresponding first electrical component or busbar 12. The multiple second connecting branch lines 153 are connected to the corresponding second electrical components. The second connecting branch lines 153 can be fixed to the shell body 11 by cable ties 16.

[0133] In the design and manufacturing of the main body 11 of the power distribution box 10 in this embodiment, the first receiving groove 11011 and the second receiving groove 1102 of the main body 11 can be arranged in a close manner, so that multiple first electrical components and multiple second electrical components can be arranged as close as possible. The opening position of the clearance hole 112 can be reasonably arranged according to the connection position of the wire harness 15, the first electrical components and the busbar 12, so that the first connecting branch line 152 of the wire harness 15 can complete the connection with a shorter extension length after passing through the clearance hole 112. The routing of the main body 151 of the wire harness, the first connecting branch line 152, the second connecting branch line 153 and the installation and fixing position of the cable tie 16 can be reasonably arranged to make full use of space and make it more convenient to disassemble and assemble the first electrical components, the busbar 12 and so on.

[0134] In this embodiment, the cavity 1101 is divided into multiple independent first receiving slots 11011 by a partition 111, which physically isolates the multiple first electrical components and increases the creepage distance between them. This allows the multiple first electrical components to be arranged more compactly while meeting the electrical clearance and creepage distance requirements. The shell body 11 also forms multiple independent second receiving slots 1102. The openings of the second receiving slots 1102 are opposite to the openings of the first receiving slots 11011 and are located on both sides of the shell body 11 in the first direction. This ensures that the second electrical components arranged in the second receiving slots 1102 are in close proximity to the second connecting branch line 153. When connecting and arranging, no additional gap is required to meet the electrical clearance requirements with the first electrical component, busbar 12, and other parts, thereby further reducing the overall volume of the power distribution box 10, making the overall structure of the power distribution box 10 more compact and occupying less space. At the same time, with the setting of the clearance hole 112, the first connecting branch line 152 can connect to the busbar 12 or the first electrical component with a shorter distance, thereby making efficient use of the space of the power distribution box 10, making the overall volume of the power distribution box 10 smaller, and thus increasing the space in the battery device 100 for assembling the battery module, thereby greatly improving the overall space utilization and energy density of the battery device 100.

[0135] In this embodiment, the main body 151 of the wiring harness and the busbar 12 are arranged on both sides of the main body 11 in the first direction. Only the part of the first connecting branch 152 of the wiring harness 15 passing through the clearance hole 112 is located on the side of the main body 11 with the busbar 12. This can effectively reduce the probability of the sharp edge of the wiring harness 15 contacting the busbar 12, thereby effectively reducing the risk of wear of the wiring harness 15, so that the power distribution box 10 can operate more stably and reliably, and thus the battery device 100 can operate more stably and reliably.

[0136] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
