Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a battery system and monitoring device. Background Technology

[0002] As the application fields of power batteries continue to expand, the market demand for them is also constantly increasing. This increased demand has led to a rapid growth in battery warehousing and logistics transportation. To ensure battery safety during warehousing and transportation, current monitoring solutions primarily involve monitoring the transport route and interior environment of the transport vehicle during transport. During warehousing, environmental monitoring or manual acquisition of battery pack status is used. This approach makes it difficult to obtain timely information on battery status and detect abnormalities during transportation and storage. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a battery system that can monitor the battery device throughout the entire transportation and storage process, thereby enabling timely detection and handling of abnormalities in the battery device to reduce losses. Simultaneously, it can also be used for routine monitoring during battery storage, such as power level detection, thus reducing the frequency and workload of regular manual inspections and consequently lowering overall operation and maintenance costs.

[0004] This application also proposes a monitoring device.

[0005] In a first aspect, embodiments of this application provide a battery system, comprising: a battery device including a housing and a battery management system, the battery management system being disposed within the housing, and a low-voltage plug connected to the battery management system being provided on the housing; and a monitoring device disposed on the housing and located outside the housing, the monitoring device being used to monitor the real-time status of the battery device during transportation and storage, the monitoring device comprising: a circuit board, a connector, a power supply, and a housing, the circuit board and the power supply being disposed within the housing, the power supply being electrically connected to the circuit board for supplying power to the circuit board, the connector being connected to the circuit board, and the connector being plugged into the low-voltage plug.

[0006] In the above technical solution, by setting up a monitoring device, the entire process of transporting and storing the battery device can be monitored, and any abnormalities in the battery device can be detected in a timely manner, so that users can deal with them promptly and reduce losses. At the same time, it can also be used for daily monitoring during storage, such as power detection, thereby reducing the frequency and workload of manual periodic inspections, thus reducing the overall operation and maintenance costs. In addition, since the monitoring device is located on the outside of the enclosure and is connected to the low-voltage plug through a connector, the monitoring device can be reused, thereby reducing resource waste and monitoring costs.

[0007] In some embodiments, the monitoring device further includes a connection component, one end of which is detachably connected to a circuit board, and the other end of which is connected to a connector.

[0008] In the above technical solution, by setting up connecting components, the connector, battery device, and circuit board are all detachable. This allows the monitoring device to be recycled and reused, and it can also be matched with various types of batteries, thus making the monitoring device adaptable. Furthermore, when matching different types of battery devices, only the connecting components and connector need to be replaced, without replacing the circuit board, which further improves the economic efficiency of the monitoring device.

[0009] In some embodiments, the connection component includes: a connector and a connection harness connecting the connector and the plug, wherein the connector is detachably connected to the circuit board.

[0010] In the above technical solution, by setting the connection components including connectors and connection harnesses, the plug and circuit board can be decoupled in terms of spatial layout, thereby solving the installation problem caused by the location limitation of the monitoring device.

[0011] In some embodiments, a cavity is formed inside the housing, and the circuit board, connector, and connection assembly are all arranged inside the cavity. An opening communicating with the cavity is formed on the housing, and the connector is arranged at the opening. A low-voltage plug is adapted to extend into the opening and connect with the connector.

[0012] In the above technical solution, by setting up a housing, the circuit board and connecting components can be integrated and made whole, so that the monitoring device can be formed as a whole, thereby improving the connection convenience between the monitoring device and the battery device; by setting a low-voltage plug suitable for insertion into the opening and plug connection, the connection position of the plug and the low-voltage plug can be protected, preventing external dust and impurities from entering, thereby further improving the connection stability between the monitoring device and the battery device; in addition, it can also reduce the space occupied by the entire battery system.

[0013] In some embodiments, the cavity includes a first cavity and a second cavity that communicate with each other, and the housing includes: a main body portion defining the first cavity, a circuit board disposed in the first cavity; a connecting portion defining the second cavity that is open at both ends, one open end of the connecting portion being connected to the main body portion, the other open end being formed as an opening, and a connector disposed in the second cavity.

[0014] In the above technical solution, by arranging the circuit board in the first cavity and the connector in the second cavity, the force of insertion and removal will not be applied to the circuit board when the monitoring device and the battery device are installed and removed, thereby reducing the probability of damage to the monitoring device during installation and removal. In addition, it can also provide all-round protection for the connector and low-voltage connector connection positions, preventing external dust and impurities from entering, thereby further improving the connection stability of the monitoring device and the battery device.

[0015] In some embodiments, the housing further includes a fixing member disposed on the connecting portion, the connecting portion being fixedly connected to the battery device via the fixing member.

[0016] In the above technical solution, the monitoring device and the battery device are fixedly connected by the fasteners provided on the connecting part, which can realize the rapid positioning and locking of the monitoring device and the battery device, thereby reducing the assembly difficulty and time cost of the monitoring device and the battery device.

[0017] In some embodiments, a plurality of mounting holes are formed on the connecting portion and arranged circumferentially along the opening. The mounting holes are threaded holes, and the fasteners are formed as fasteners. There are multiple fasteners, and each fastener corresponds to one of the mounting holes. The fasteners are inserted into the corresponding mounting holes, and one end of the fastener that extends into the second cavity abuts against the outer peripheral surface of the low-voltage plug.

[0018] In the above technical solution, by setting a fastener as a fixing component, and by having one end of the fastener inserted into the second cavity abut against the outer peripheral surface of the low-voltage plug to fix the monitoring device and the battery device, the assembly process of the monitoring device and the battery device can be simplified, thereby improving the assembly efficiency of the monitoring device and the battery device; at the same time, it can also prevent damage to the battery body after disassembly, reduce physical damage caused by disassembly and assembly, and thus ensure the integrity of the battery casing.

[0019] In some embodiments, the housing further includes a reinforcing rib, which is disposed on the outer peripheral surface of the connection portion and extends circumferentially around the opening in an annular shape, and a mounting hole is disposed on the reinforcing rib.

[0020] In the above technical solution, by setting reinforcing ribs, the structural strength of the connection position can be further improved, thereby improving the connection stability between the monitoring device and the battery device.

[0021] In some embodiments, the housing includes: a first housing and a second housing, wherein a first cavity is formed in the first housing, the first cavity is open on one side in a first direction, a circuit board and a connector are detachably arranged in the first cavity, and the second housing is connected to the first housing and arranged on one side of the first housing in the first direction for sealing or opening the open side of the first cavity.

[0022] In the above technical solution, by setting a first housing and a second housing, the circuit board and connector are detachably arranged in the first cavity. The second housing is connected to the first housing and is used to cover or open the open side of the first cavity, so that the circuit board and connector can be taken out from the housing, which is conducive to the maintenance or replacement of the circuit board and connector. In this way, the maintenance cost of the entire monitoring device can be reduced. At the same time, since the connector can be replaced, after the monitoring device is recycled, only the connector needs to be replaced to adapt to other battery devices of other specifications. Thus, resource waste and monitoring costs can be reduced.

[0023] In some embodiments, the monitoring device further includes: a first sensor assembly disposed on a circuit board for detecting environmental information of the battery device, the first sensor assembly including one or more of a temperature sensor, a humidity sensor, and a barometric pressure sensor; and / or a second sensor assembly disposed on a circuit board for detecting position information of the battery device, the second sensor assembly including one or more of a triaxial accelerometer and an attitude sensor; and / or a positioning module and an alarm device, the positioning module being used to locate the position of the battery device; the alarm device being communicatively connected to the positioning module.

[0024] In the above technical solution, by setting up a first sensor component, the environmental information of the battery device can be detected intermittently or in real time. This environmental information can then be used to determine whether the battery device is in an abnormal state, such as thermal runaway, allowing for early detection and handling to reduce losses. Simultaneously, it can confirm whether the battery device's placement environment meets requirements, such as whether temperature, humidity, and ventilation conditions are within permissible ranges for battery storage. This allows staff to take timely measures when the storage environment is substandard, reducing performance degradation or safety hazards caused by unsuitable environments. By setting up a second sensor, the three-dimensional attitude of the battery device can be monitored, ensuring the reliability of its storage and placement. By setting up a positioning module and an alarm device, an alarm signal can be issued if the battery device deviates from a preset trajectory. This allows staff to promptly detect and handle abnormalities, improving the reliability of the battery module during transportation and storage.

[0025] In some embodiments, the monitoring device further includes: a data storage module disposed on a circuit board for storing status data of the battery device; and / or a wireless communication module disposed on the circuit board and configured to transmit the status data of the battery device to a user terminal.

[0026] In the above technical solution, by setting up a data storage module, the detection data can be stored first and then transmitted via communication. In this way, even if communication is interrupted, the data can still be ensured not to be lost, and it can be retransmitted after communication is restored, thereby ensuring the complete traceability of historical data. By setting up a wireless communication module, the detection data can be uploaded to the user terminal in a timely manner, eliminating the need for personnel to go to the site to copy it, thereby further reducing the workload of personnel and thus reducing the overall operation and maintenance costs.

[0027] Secondly, embodiments of this application also provide a monitoring device, which is a monitoring device in the battery system according to the first aspect.

[0028] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0053] 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 in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in aerospace and other fields. With the continuous expansion of power battery applications, market demand is also constantly increasing. This increased demand has led to a rapid growth in battery warehousing and logistics transportation.

[0054] To ensure battery safety during warehousing and logistics transportation, current monitoring solutions mostly involve monitoring the transportation route and the environment inside the vehicle during transportation. During warehousing, environmental monitoring or manual acquisition of the battery pack status is used. This makes it impossible to obtain the battery status in a timely manner during transportation and warehousing.

[0055] Based on the above considerations, in order to solve the problem of the inability to obtain the battery status in a timely manner during the transportation and storage of battery packs, embodiments of this application provide a battery system. The battery system includes a battery device and a monitoring device. The battery device includes a housing and a battery management system. The battery management system is arranged inside the housing. The housing is provided with a low-voltage plug connected to the battery management system. The monitoring device is located on the housing and outside the housing. The monitoring device is used to monitor the real-time status of the battery device during transportation and storage. The monitoring device includes a circuit board, a connector, a power supply, and a housing. The circuit board and the power supply are both arranged inside the housing. The power supply is electrically connected to the circuit board and is used to supply power to the circuit board. The connector is connected to the circuit board and is plugged into the low-voltage plug. Therefore, during transportation and operation, the monitoring device can monitor the environmental status, location status, and battery status of the battery device in real time, and upload the data synchronously to the cloud platform. This allows staff to promptly detect abnormalities in the battery device, enabling users to handle them in a timely manner and reduce losses. Furthermore, during warehousing, the monitoring device can also be used for daily monitoring, that is, by periodically waking up the battery management system to read SOC data, thereby monitoring the status data of the battery device. This reduces the frequency and workload of manual periodic inspections, thereby reducing the overall operation and maintenance costs.

[0056] The following is for reference. Figures 1-7 A battery system 1 according to an embodiment of the first aspect of this application is described. Figure 1 This is a schematic diagram of a battery system 1 according to some embodiments of this application; Figure 2 This is a partial cross-sectional view of a battery system 1 according to some embodiments of this application. Figure 3 yes Figure 1 An exploded view of the monitoring device 100 shown; Figure 4 yes Figure 3 A schematic diagram showing the connection between the circuit board 10 and the connecting assembly 20; Figure 5 yes Figure 1 A schematic diagram of the monitoring device 100 shown; Figure 6 yes Figure 1 Cross-sectional view of the monitoring device 100 shown; Figure 7 This is a partial schematic diagram of the monitoring device 100.

[0057] An embodiment of this application provides a battery system 1, referring to... Figure 1 The battery system 1 includes a battery device 200 and a monitoring device 100.

[0058] The battery device 200 can be used in electrical devices that use batteries as a power source 40 or in various energy storage systems that use batteries as energy storage elements. The battery device 200 generally includes components such as battery cells for storing and releasing electrical energy, a battery management system for monitoring the operating status of the battery device 200, and a housing that provides installation space for the battery cells and the battery management system.

[0059] Specifically, the battery device 200 includes a housing and a battery management system. The battery management system is housed within the housing, and the housing is equipped with a low-voltage connector 201 for connecting to the battery management system. The battery management system is used to monitor and manage the battery. By collecting and calculating parameters such as voltage, current, temperature, and SOC, it controls the charging and discharging process of the battery, thereby protecting the battery and improving its overall performance. The housing provides installation space for the battery cells and the battery management system, while the low-voltage connector 201 is the key interface for connecting the battery management system to the external vehicle.

[0060] The monitoring device 100 is installed on the box and located on the outside of the box. The monitoring device 100 is used to monitor the real-time status of the battery device 200 during transportation and storage.

[0061] The statement that "the monitoring device 100 is located on the box and on the outside of the box" is intended to indicate that the monitoring device 100 is an additional component that is connected to the assembled battery device 200 after the battery device 200 is assembled, rather than a component assembled inside the battery device 200, and does not occupy the internal space of the battery device 200.

[0062] "The monitoring device 100 is used to monitor the real-time status of the battery device 200 during transportation and storage." The real-time status can include the battery's real-time charge level, operating status, and operating temperature. Therefore, by monitoring the battery device 200's status in real time, any abnormalities can be detected promptly, allowing users to address them and reduce losses. Furthermore, it can be used for routine monitoring, reducing the frequency and workload of regular manual inspections and thus lowering overall maintenance costs.

[0063] For example, during transportation, the monitoring device 100 monitors the environmental and location status of the battery device 200 in real time, and the data is uploaded to the cloud platform synchronously. During storage, the monitoring device 100 can also periodically wake up the battery management system to read the SOC data, thereby enabling real-time monitoring of the status data of the battery device 200.

[0064] The monitoring device 100 includes: a circuit board 10, a connector 22, a power supply 40, and a housing 30. The circuit board 10 and the power supply 40 are both arranged inside the housing 30. The power supply 40 is electrically connected to the circuit board 10 and is used to supply power to the circuit board 10. The connector 22 is connected to the circuit board 10 and is plugged into the low-voltage connector 201.

[0065] The housing 30 provides installation space and protection for the circuit board 10 and the power supply 40; the circuit board 10 is the core component responsible for mounting various electronic components to achieve real-time monitoring of the battery device 200; the power supply 40 is the component used to supply power to the circuit board 10; and the connector 22 is the component used to connect the circuit board 10 and the low-voltage connector 201.

[0066] The statement that "power supply 40 is electrically connected to circuit board 10 to supply power to circuit board 10, connector 22 is connected to circuit board 10, and connector 22 is plugged into low-voltage connector 201" aims to indicate that power supply 40 can supply power to the battery management system through connector 22, waking up the battery management system from its dormant state, and thus obtaining battery status data from battery device 200. It should be noted that the battery status data includes at least one of temperature, voltage, insulation resistance, and relay status.

[0067] It should be noted that the circuit board 10 is generally equipped with a main control chip, which generally supports multi-protocol communication, has low-power wake-up and data processing capabilities, and has a built-in verification algorithm to ensure data transmission integrity; the power supply 40 can be a rechargeable lithium battery pack, so that the monitoring device 100 can be used cyclically.

[0068] The phrase "connector 22 is connected to circuit board 10, and connector 22 is plugged into low-voltage connector 201" can also be understood as follows: the monitoring device 100 is electrically connected to battery device 200 through connector 22, and the monitoring device 100 and battery device 200 are detachably connected. That is, the monitoring device 100 of this application can be installed as needed and removed when not in use, thereby achieving reusability and reducing resource waste and monitoring costs.

[0069] It should be noted that the low-voltage plug 201 on the box is a component used to connect with an external vehicle. In other words, the monitoring device 100 in this embodiment uses the original electrical connection structure of the battery device 200 to achieve electrical connection with the battery device 200. That is, the monitoring device 100 can achieve real-time monitoring of the battery device 200 during transportation and storage without adding additional connection parts 32.

[0070] In the above technical solution, by setting up the monitoring device 100, the battery device 200 can be monitored throughout the entire process of transportation and storage, and any abnormalities in the battery device 200 can be detected in a timely manner, so that users can deal with them in a timely manner and reduce losses. At the same time, it can also be used for daily monitoring during storage, such as power detection, thereby reducing the frequency and workload of manual periodic inspections, and thus reducing the overall operation and maintenance costs. In addition, since the monitoring device 100 is located on the outside of the enclosure and is connected to the low-voltage plug 201 through the connector 22, the monitoring device 100 can be reused, thereby reducing resource waste and monitoring costs.

[0071] In some embodiments, such as Figure 3 As shown, the monitoring device 100 also includes a connection component 20, one end of which is detachably connected to the circuit board 10, and the other end of which is connected to the connector 22.

[0072] It is understood that the connection component 20 and the connector 22 are connected together to form a transmission component. The circuit board 10 is connected to the battery device 200 through this transmission component to transmit a wake-up signal to the battery management system to wake up the battery management system and then obtain the status signal of the battery device 200.

[0073] "One end of the connecting component 20 is detachably connected to the circuit board 10, and the other end of the connecting component 20 is connected to the connector 22." This means that the connector 22 is detachably connected to both the circuit board 10 and the battery device 200. This allows the monitoring device 100 to be recycled and reused, and also makes the connector 22 replaceable. Therefore, when matching different models of battery devices 200, only the connecting component 20 and the connector 22 need to be replaced, which can further improve the economy of the monitoring device 100.

[0074] In the above technical solution, by setting the connecting component 20, the connector 22, the battery device 200, and the circuit board 10 are all detachable. In this way, the monitoring device 100 can be recycled and reused, and can be matched with various types of batteries, thus making the monitoring device 100 adaptable. Moreover, when matching different types of battery devices 200, only the connecting component 20 and the connector 22 need to be replaced, and the circuit board 10 does not need to be replaced, thereby further improving the economy of the monitoring device 100.

[0075] In some embodiments, such as Figures 3-4 As shown, the connection assembly 20 includes a connector 21 and a connection harness 23 connecting the connector 21 and the plug 22. The connector 21 is detachably connected to the circuit board 10.

[0076] Specifically, connector 21 is used to realize the electrical connection between the connecting component 20 and the circuit board 10; connecting wire harness 23 is used to realize the electrical connection between connector 21 and plug 22; plug 22 is used to realize the electrical connection between the connecting component 20 and the battery device 200.

[0077] The connection component 20 includes a connector 21 and a connection harness 23. It is understood that the connector 22, which is plugged into the low-voltage plug 201, is not directly fixed to the circuit board 10, but is connected to the circuit board 10 through the connection harness 23 and the connector 21. This allows a certain distance to be formed between the connector 22 and the circuit board 10. Since the connection harness 23 is generally made of flexible material, the design of the connection harness 23 allows the connector 22 and the circuit board 10 to be decoupled in terms of spatial layout, thereby solving the installation problem of the monitoring device 100 caused by the location limitation.

[0078] In the above technical solution, by setting the connection component 20 to include a connector 21 and a connection harness 23, the plug 22 and the circuit board 10 can be decoupled in terms of spatial layout, thereby solving the installation problem of the monitoring device 100 caused by location limitations.

[0079] In some embodiments, such as Figures 5-6 As shown, a cavity is formed inside the housing 30, and the circuit board 10 and the connecting assembly 20 are both arranged inside the cavity. An opening 33 communicating with the cavity is formed on the housing 30, and the connector 22 is arranged at the opening 33. The low-voltage plug 201 is adapted to extend into the opening 33 and be plugged into the connector 22 for connection.

[0080] Specifically, the housing 30 can provide protection for the circuit board 10, connector 22 and connection component 20. At the same time, it can also realize the integration and wholeness of the circuit board 10, connector 22 and connection component 20, so that the monitoring device 100 can be formed as a whole, thereby improving the connection convenience between the monitoring device 100 and the battery device 200.

[0081] The phrase "the connector 22 is arranged at the opening 33, and the low-voltage plug 201 is adapted to extend into the opening 33 and connect with the connector 22" is intended to indicate that the connection position of the connector 22 and the low-voltage plug 201 is located inside the housing 30. Thus, the housing 30 can protect the connection position of the connector 22 and the low-voltage plug 201, preventing external dust and impurities from entering, thereby further improving the connection stability of the monitoring device 100 and the battery device 200. In addition, since at least a part of the low-voltage plug 201 extends into the housing 30, the space occupied by the entire battery system 1 can also be reduced.

[0082] Optionally, the housing 30 is made of lightweight, high-strength materials (such as ABS engineering plastic or aluminum alloy), and has IP67 dustproof and waterproof properties, making it suitable for various battery pack installation scenarios.

[0083] In the above technical solution, by setting the housing 30, the integration and wholeness of the circuit board 10 and the connecting component 20 can be achieved, making the monitoring device 100 a whole unit, thereby improving the connection convenience between the monitoring device 100 and the battery device 200; by setting the low-voltage plug 201 to be suitable for inserting into the opening 33 and connecting with the connector 22, the connection position of the connector 22 and the low-voltage plug 201 can be protected, preventing external dust and impurities from entering, thereby further improving the connection stability between the monitoring device 100 and the battery device 200; in addition, the space occupied by the entire battery system 1 can be reduced.

[0084] In some embodiments, such as Figures 5-6 As shown, the cavity includes a first cavity 311 and a second cavity 321 that are interconnected. The housing 30 includes a main body 31 and a connecting part 32. The main body 31 defines the first cavity 311, and the circuit board 10 is arranged in the first cavity 311. The connecting part 32 defines the second cavity 321, which is open at both ends. One open end of the connecting part 32 is connected to the main body 31, and the other open end is formed as an opening 33. The connector 22 is arranged in the second cavity 321.

[0085] Specifically, in this embodiment, the circuit board 10 and the connector 22 are respectively arranged in two interconnected but functionally independent cavities. In this way, functional partitioning can be achieved, and the connector 32 is separated from the central control system. As a result, when the monitoring device 100 and the battery device 200 are installed and removed, the force of insertion and removal will not act on the circuit board 10, thereby reducing the probability of damage to the monitoring device 100 during installation and removal.

[0086] "The connecting part 32 defines a second cavity 321 that is open at both ends, and the connector 22 is arranged in the second cavity 321." It can be understood that the connecting part 32 wraps around the connector 22 like a sleeve. In this way, while achieving connection with the low-voltage socket, it can also form all-round mechanical support for the connector 22 and the low-voltage plug 201, and achieve all-round protection for the connection position of the connector 22 and the low-voltage plug 201.

[0087] Optionally, the size of the second cavity 321 is adapted to the size of various low-voltage plugs 201, so that when the monitoring device 100 is recycled, the housing 30 does not need to be replaced, thereby further improving the economy of the monitoring device 100.

[0088] In the above technical solution, by arranging the circuit board 10 in the first cavity 311 and the connector 22 in the second cavity 321, the force of insertion and removal will not be applied to the circuit board 10 when the monitoring device 100 and the battery device 200 are installed and removed, thereby reducing the probability of damage to the monitoring device 100 during installation and removal. In addition, it can also provide all-round protection for the connection positions of the connector 22 and the low-voltage connector 201, preventing external dust and impurities from entering, thereby further improving the connection stability of the monitoring device 100 and the battery device 200.

[0089] In some embodiments, the housing 30 further includes a fixing member disposed on the connecting portion 32, and the connecting portion 32 is fixedly connected to the battery device 200 through the fixing member.

[0090] In the above technical solution, the monitoring device 100 and the battery device 200 are fixedly connected by the fastener provided on the connecting part 32, which can realize the rapid positioning and locking of the monitoring device 100 and the battery device 200, thereby reducing the assembly difficulty and time cost of the monitoring device 100 and the battery device 200.

[0091] In some embodiments, such as Figures 5-6 As shown, a plurality of mounting holes 37 are formed on the connecting part 32, which are arranged circumferentially along the opening 33. The mounting holes 37 are threaded holes, and the fasteners are formed as fasteners. There are multiple fasteners, and each fastener corresponds to one of the mounting holes 37. The fasteners are inserted into the corresponding mounting holes 37, and one end of the fastener that extends into the second cavity 321 abuts against the outer peripheral surface of the low-voltage plug 201.

[0092] Specifically, once the low-voltage plug 201 and the connector 22 are plugged in, the fastener can be inserted into the mounting hole 37 so that one end of the fastener abuts against the outer peripheral surface of the low-voltage plug 201. This simultaneously completes the electrical connection and mechanical fixation. In other words, this embodiment does not require additional design of brackets, clips or other components to achieve mechanical fixation between the monitoring device 100 and the battery device 200, thereby greatly simplifying the installation process and improving assembly efficiency.

[0093] For example, the number of fasteners can be two, three, or more, and the number of mounting holes 37 is the same as the number of fasteners. For example, as shown in the figure, there are four mounting holes 37, which are arranged on the four surfaces of the connecting part 32, and the two mounting holes 37 arranged opposite each other are arranged face to face, which can further improve the installation stability.

[0094] In the above technical solution, by setting a fastener as a fixing member, and by having one end of the fastener extending into the second cavity 321 abut against the outer peripheral surface of the low-voltage plug 201 to fix the monitoring device 100 and the battery device 200, the assembly process of the monitoring device 100 and the battery device 200 can be simplified, thereby improving the assembly efficiency of the monitoring device 100 and the battery device 200; at the same time, the battery body can be disassembled without damage, reducing physical damage caused by disassembly and assembly, thereby ensuring the integrity of the battery casing.

[0095] In some embodiments, such as Figure 5 As shown, the housing 30 also includes a reinforcing rib 36, which is disposed on the outer peripheral surface of the connecting portion 32 and extends in a ring around the opening 33. The mounting hole 37 is disposed on the reinforcing rib 36.

[0096] In the above technical solution, by setting the reinforcing rib 36, the structural strength of the connection position can be further improved, thereby improving the connection stability between the monitoring device 100 and the battery device 200.

[0097] In some embodiments, such as Figure 3 and Figure 7 As shown, the housing 30 includes: a first housing 34 and a second housing 35. A first cavity 341 is formed inside the first housing 34. The first cavity 341 is open on one side in the first direction X. The circuit board 10 and the connector 22 are detachably arranged inside the first cavity 341. The second housing 35 is connected to the first housing 34 and is arranged on one side of the first housing 34 in the first direction X, for sealing or opening the open side of the first cavity 341.

[0098] The phrase "the second housing 35 is connected to the first housing 34 and is arranged on one side of the first housing 34 in the first direction X, for sealing or opening the open side of the first cavity 341" means that the second housing 35 and the first housing 34 can be detachably connected or movably connected, such as by a pin connection, in which the second housing 35 can rotate relative to the first housing 34 around the pin to open the open side of the first cavity 341.

[0099] Optionally, a locking protrusion is formed inside the first housing 34, and a locking groove is formed on the connector 22. The locking protrusion fits into the locking groove so that the connector 22 is locked and connected to the first housing 34. The structure of the locking protrusion and the locking groove is relatively simple, which can reduce the production cost of the entire device.

[0100] In the above technical solution, by setting a first housing 34 and a second housing 35, the circuit board 10 and the connector 22 are detachably arranged in the first cavity 341. The second housing 35 is connected to the first housing 34 and is used to cover or open the open side of the first cavity 341, so that the circuit board 10 and the connector 22 can be taken out from the housing 30, which is conducive to the maintenance or replacement of the circuit board 10 and the connector 22. In this way, the maintenance cost of the entire monitoring device 100 can be reduced. At the same time, since the connector 22 can be replaced, after the monitoring device 100 is recycled, only the connector 22 needs to be replaced to adapt it to other specifications of battery devices 200. Thus, resource waste and monitoring costs can be reduced.

[0101] In some embodiments, the monitoring device 100 further includes: a first sensor assembly disposed on the circuit board 10 for detecting environmental information of the battery device 200, the first sensor assembly including one or more of a temperature sensor, a humidity sensor, and a barometric pressure sensor.

[0102] Among them, the temperature sensor is mainly used to detect the ambient temperature; the humidity sensor is mainly used to detect the ambient humidity; and the air pressure sensor is mainly used to detect the ambient air pressure.

[0103] In some embodiments, the monitoring device 100 further includes a second sensor assembly disposed on the circuit board 10 for detecting the position information of the battery device 200. The second sensor assembly includes one or more of a triaxial accelerometer and an attitude sensor.

[0104] It is understandable that the second sensor assembly can be a triaxial accelerometer, an attitude sensor, or both. The triaxial accelerometer is primarily used to measure the linear acceleration of the battery device 200 in three-dimensional space, i.e., to reflect the direction in which the battery device 200 is moving and its velocity. The attitude sensor is primarily used to determine the complete attitude of the battery device 200 in three-dimensional space, i.e., its orientation and rotation state; it is mainly used to display how an object is positioned and rotates in space.

[0105] It should be noted that in some cases, the attitude sensor includes a triaxial accelerometer. Therefore, in some specific embodiments, only an attitude sensor may be provided.

[0106] In some embodiments, the monitoring device 100 further includes a positioning module and an alarm device, wherein the positioning module is used to locate the position of the battery device 200; and the alarm device is communicatively connected to the positioning module.

[0107] For example, the positioning module can be an integrated BeiDou / GPS composite positioning module, which supports high-precision trajectory tracking and electronic fence functions, thereby further improving the positioning accuracy of the positioning module. The positioning module is mainly used to record the displacement trajectory of the battery device 200. It should be noted that the displacement trajectory can be the transportation route during transportation, or the displacement trajectory on a storage shelf or fixed frame.

[0108] Optionally, the alarm device is communicatively connected to the first sensor assembly and the second sensor assembly. In this way, when the ambient temperature or location information deviates from the preset target, the alarm device will also issue an alarm signal, such as issuing an audible alarm or a signal alarm at the user end.

[0109] In the above technical solution, by setting up a first sensor component, the environmental information of the battery device 200 can be detected intermittently or in real time. This environmental information can then be used to determine whether the battery device 200 is in an abnormal state, such as thermal runaway, allowing for early detection and handling to reduce losses. Simultaneously, it can confirm whether the placement environment of the battery device 200 meets requirements, such as whether temperature, humidity, and ventilation conditions are within the permissible range for battery storage. This allows staff to take timely measures when the storage environment is substandard, reducing performance degradation or safety hazards caused by unsuitable environments. By setting up a second sensor component, the three-dimensional attitude of the battery device 200 can be monitored to ensure the reliability of its storage placement. By setting up a positioning module and an alarm device, an alarm signal can be issued when the battery device 200 deviates from a preset trajectory. This allows staff to promptly detect and handle abnormalities, improving the reliability of the battery module during transportation and storage.

[0110] In some embodiments, the monitoring device 100 further includes a data storage module, which is disposed on the circuit board 10 and is used to store the status data of the battery device 200.

[0111] For example, the data storage module can integrate onboard Flash memory and a replaceable memory card interface on the circuit board, enabling the data storage module to support cyclic overwrite storage and manual data export.

[0112] In the above technical solution, by setting up a data storage module, the detection data can be stored first and then transmitted via communication. In this way, even if communication is interrupted, the data can still be ensured not to be lost, and it can be retransmitted after communication is restored, thereby ensuring the complete traceability of historical data.

[0113] In some embodiments, the monitoring device 100 further includes a wireless communication module, which is disposed on the circuit board 10 and configured to transmit the status data of the battery device 200 to the user terminal.

[0114] For example, the wireless communication module can use an embedded SIM or a physical SIM card to upload real-time data to a cloud management platform via the MQTT protocol and synchronize it with local storage.

[0115] Embedded SIM cards integrate the SIM card functionality directly into the device's main chip or a dedicated eSIM chip (eUICC), eliminating the need for a physical card slot. This further enhances the integration of the monitoring device 100, contributing to its miniaturization and thinner design. Physical SIM cards require a SIM card slot on the circuit board, where the SIM card is inserted. This insertion method facilitates maintenance and reduces repair complexity. It's worth noting that both embedded and physical SIM cards can employ a dual-mode structure, allowing for one-for-one backup, thereby improving the reliability and lifespan of the wireless communication module.

[0116] In the above technical solution, by setting up a wireless communication module, the detection data can be uploaded to the user terminal in a timely manner without the need for personnel to go to the site to copy it, thereby further reducing the workload of personnel and thus reducing the overall operation and maintenance costs.

[0117] Secondly, embodiments of this application also provide a monitoring device 100, which is the monitoring device 100 in the battery system 1 according to the first aspect.

[0118] The following will refer to Figures 1-7 This application describes a monitoring device 100 according to a specific embodiment of the present application. The monitoring device 100 is electrically connected to the battery management system of the battery device 200 and is used to monitor the real-time status of the battery device 200 during transportation and storage.

[0119] Reference Figure 3 The monitoring device 100 includes: a circuit board 10, a connecting component 20, a connector 22, and a power supply 40. One end of the connecting component 20 is detachably connected to the circuit board 10, and the other end of the connecting component 20 is connected to the connector 22. The connector 22 is plugged into the low-voltage connector 201 of the battery management system. The power supply 40 is electrically connected to the circuit board 10 to supply power to the circuit board 10. The power supply 40 is also electrically connected to the battery management system through the connecting component 20 to supply power to the battery management system, thereby waking up the dormant battery management system and thus monitoring the status of the battery device 200.

[0120] Specifically, the connection assembly 20 includes: a connector 21 and a connection harness 23 connecting the connector 21 and the plug 22. The connector 21 is detachably connected to the circuit board 10, and the plug 22 is plugged into the low-voltage plug 201 of the battery device 200.

[0121] The monitoring device 100 further includes a housing 30, within which a cavity is formed, comprising a first cavity 311 and a second cavity 321 that are interconnected. The housing 30 includes a main body 31 and a connecting part 32. The main body 31 defines the first cavity 311, and the circuit board 10 is disposed within the first cavity 311. The connecting part 32 defines a second cavity 321 that is open at both ends. One open end of the connecting part 32 is connected to the main body 31, and the other open end is formed as an opening 33. A connector 22 is disposed within the second cavity 321, and a low-voltage connector 201 is adapted to extend into the opening 33 and be plugged into the connector 22 for connection.

[0122] The housing 30 also includes a fixing member, which is disposed on the connecting portion 32, and the connecting portion 32 is fixedly connected to the battery device 200 through the fixing member. Specifically, the connecting portion 32 has a plurality of mounting holes 37 arranged circumferentially along the opening 33. The mounting holes 37 are threaded holes. The fixing member is formed as a fastener. There are multiple fasteners, and each fastener corresponds to one of the mounting holes 37. The fasteners pass through the corresponding mounting holes 37, and one end of the fastener that extends into the second cavity 321 abuts against the outer peripheral surface of the low-voltage plug 201.

[0123] The housing 30 also includes a reinforcing rib 36, which is disposed on the outer peripheral surface of the connecting portion 32 and extends in a ring around the opening 33. A mounting hole 37 is disposed on the reinforcing rib 36.

[0124] The housing 30 includes a first housing 34 and a second housing 35, which are fitted together to form a main body 31 and a connecting part 32. A first cavity 341 is formed inside the first housing 34. The first cavity 341 is open on one side in the first direction X. The circuit board 10 and the connector 22 are detachably arranged inside the first cavity 341. The second housing 35 is connected to the first housing 34 and is arranged on one side of the first housing 34 in the first direction X, for sealing or opening the open side of the first cavity 341.

[0125] The monitoring device 100 also includes: a first sensor assembly, a second sensor assembly, a positioning module, and an alarm device. The first sensor assembly, mounted on the circuit board 10, is used to detect environmental information of the battery device 200 and includes one or more of a temperature sensor, a humidity sensor, and a barometric pressure sensor. The second sensor assembly, mounted on the circuit board 10, is used to detect the position information of the battery device 200 and includes one or more of a triaxial accelerometer and an attitude sensor. The positioning module is used to locate the position of the battery device 200. The alarm device is communicatively connected to the positioning module. The arrangement of the first sensor assembly, the second sensor assembly, and the positioning module enables multi-dimensional monitoring of the monitoring device 100, allowing it to integrate environmental parameters, mechanical status, and battery status monitoring, thereby providing full lifecycle data support.

[0126] The monitoring device 100 also includes a data storage module and a wireless communication module. The data storage module is located on the circuit board 10 and is used to store the status data of the battery device 200. The wireless communication module is located on the circuit board 10 and is configured to transmit the status data of the battery device 200 to the user terminal. Specifically, data transmission and local storage are carried out in parallel, that is, data is first written to the onboard memory, and automatic retransmission is performed when communication is interrupted and resumed. It supports OTA firmware upgrades and can update monitoring parameter thresholds and algorithm models through the cloud.

[0127] Specifically, when the battery device 200 is assembled and needs to be transported and stored, it can be fixed to the low-voltage plug 201 of the battery device 200 via the connector 22, and then the monitoring device 100 is fixed to the battery device 200 by circumferentially abutting the low-voltage plug 201 with fasteners. When it is necessary to monitor the battery device 200, the battery management system of the power battery is activated by the circuit board 10, and then core parameters such as SOC, SOH, and cell voltage are read via the CAN bus protocol. At the same time, the first sensor component is used to collect real-time temperature, humidity, air pressure, and vibration data around the battery device 200, and the tilt angle is monitored by the attitude sensor. The positioning module records the displacement trajectory of the battery pack. When abnormal data occurs (such as overheating or severe vibration), a threshold alarm is triggered and sent to the user's management platform via the wireless communication module (SIM card module).

[0128] In the above technical solution, by setting up the monitoring device 100, the real-time status of the battery device 200 during transportation and storage can be realized, and any abnormalities in the battery device 200 can be detected in a timely manner, so that users can deal with them in a timely manner and reduce losses. At the same time, it can also be used for daily monitoring during storage, such as power detection, thereby reducing the frequency and workload of manual periodic inspections, thus reducing the overall operation and maintenance costs. In addition, since the monitoring device 100 is located on the outside of the enclosure and is connected to the low-voltage plug 201 through the connector 22, the monitoring device 100 can also be reused, thereby reducing resource waste and monitoring costs.

[0129] 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.
