Description

Technical Field

[0002] Due to the advantages of lithium-ion batteries such as high energy density, high number of cycles, light weight and high performance, they have gradually become an indispensable and important part of the electrochemical energy storage industry and are widely used in various energy storage scenarios. In order to increase energy density and reduce costs, lithium-ion batteries are developing in the direction of large capacity and large volume. The high energy density, high charge and discharge rate and long life of lithium batteries make their application scenarios more and more extensive, especially in load-bearing application scenarios. The greater the load of the drone or ship, the larger the battery capacity required and the more battery strings are needed.

[0003] However, the conventional battery pack assembly method is to connect all the cells in series together. If the number of strings is high, the entire battery pack will be larger, requiring the electrical equipment to plan a larger space for assembling the battery pack. Furthermore, when the terminal product has limited space or is sensitive to its own center of gravity, the use of such a large battery pack will be limited. Moreover, because the battery pack is large in size, thicker and stronger materials are required for assembly, and each battery module needs to be connected to the BMS using a wiring harness. The larger the volume, the longer the required wiring harness length, resulting in difficulty in assembling the battery pack and excessive cost. Summary of the invention

By processing the package group assembly adjustment of the subpackaging environment parameters and the preset environment parameters, it is convenient to determine the difference in the application environment of the battery pack. After obtaining the subpackaging adjustment amount, the degree of difference in the application environment of the battery pack is determined, which is convenient for controlling the assembly mode of each module of the battery pack, so that the distribution of the battery pack is adapted to the application environment, thereby reducing the difficulty and cost of assembly.

[0041] In this embodiment, after collecting the sub-packaging environmental parameters, the battery assembly application environment state of the battery pack is determined, and then the sub-packaging environmental parameters are compared with the standard environmental parameters to facilitate the determination of the difference between the current battery assembly application environment state of the battery pack and the specified application environment state. Finally, according to the above difference value, the assembly mode of the battery pack is optimized and adjusted to facilitate the adjustment of the installation method of each module of the battery pack to select an assembly method suitable for the current application environment, which effectively reduces the difficulty and cost of battery pack assembly. Among them, the battery pack is formed by connecting multiple battery modules in series and parallel, and the assembly mode is used for the distributed assembly of each battery module.

[0042] In one of the embodiments, the obtaining of the subpackaging environmental parameters of the battery pack includes: obtaining the battery subpackaging application humidity of the battery pack. In this embodiment, the subpackaging environmental parameters are the battery assembly application environment data of the battery pack, that is, the subpackaging environmental parameters are the use environment of the battery pack, that is, the subpackaging environmental parameters correspond to the working environment of the battery pack.

The subpackaging environmental parameters include the battery subpackaging application humidity of the battery pack, and the battery subpackaging application humidity is the ambient humidity of the environment in which the battery pack is applied. By collecting the battery subpackaging application humidity, it is convenient to determine the assembly and use environment of the battery pack.

[0043] Further, the subpackaging environmental parameters and the preset environmental parameters are subjected to a package-by-package adjustment process to obtain a subpackaging adjustment amount, including: obtaining the adjustment of the battery subpackaging application humidity and the preset application humidity to obtain a subpackaging humidity difference. In this embodiment, the subpackaging environmental parameters are the battery assembly application environment data of the battery pack, that is, the subpackaging environmental parameters are the use environment of the battery pack, that is, the subpackaging environmental parameters correspond to the working environment of the battery pack. By collecting the subpackaging environmental parameters, it is convenient to determine the assembly condition of the battery pack in the environment to be applied. The preset environmental parameters are the battery assembly reference application environment data of the battery pack, that is, the preset environmental parameters are the standard use environment of the battery pack, that is, the preset environmental parameters correspond to the specified working environment of the battery pack. By performing a package-by-package adjustment process on the subpackaging environmental parameters and the preset environmental parameters, it is convenient to determine the differences in the application environment of the battery pack. The subpackaging environmental parameters include the battery subpackaging application humidity of the battery pack. The battery subpackaging application humidity is the environmental humidity of the environment in which the battery pack is used. By collecting the battery subpackaging application humidity, it is convenient to determine the assembly and use environment of the battery pack. The preset application humidity is the environmental humidity in which the battery pack is to be used. By adjusting the battery subpackaging application humidity and the preset application humidity, the least square difference between the environmental humidity of the battery pack and the specified environmental humidity is obtained to reduce the error of the subpackaging humidity difference.

[0044] Furthermore, the distributed sub-assembly disabling signal is sent to the battery assembly system according to the sub-assembly adjustment amount to adjust the assembly mode of each module of the battery pack in the energy storage cabinet, including: detecting whether the sub-assembly humidity difference is greater than or equal to the preset humidity difference; when the sub-assembly humidity difference is greater than or equal to the preset humidity difference, a distributed sub-assembly enabling signal is sent to the battery assembly system to enable each module of the battery pack to be installed in a distributed manner. In this embodiment, the sub-assembly adjustment amount is obtained based on the sub-assembly environmental parameters and the preset environmental parameters, and the sub-assembly environmental parameters are the battery assembly application environment data of the battery pack, that is, the sub-assembly environmental parameters are the use environment of the battery pack, that is, the sub-assembly environmental parameters correspond to the working environment of the battery pack. By collecting the sub-assembly environmental parameters, it is convenient to determine the assembly status of the battery pack in the environment to be applied. The preset environmental parameters are the battery assembly reference application environment data of the battery pack, that is, the preset environmental parameters are the standard use environment of the battery pack, that is, the preset environmental parameters correspond to the specified working environment of the battery pack. By processing the package group packaging adjustment of the subpackaging environmental parameters and the preset environmental parameters, it is convenient to determine the differences in the application environment of the battery pack. After obtaining the subpackaging adjustment amount, the degree of difference in the application environment of the battery pack is determined, which is convenient for controlling the assembly method of each module of the battery pack so that the distribution of the battery pack adapts to the application environment, thereby reducing the difficulty and cost of assembly. The subpackaging environmental parameters include the battery subpackaging application humidity of the battery pack. The battery subpackaging application humidity is the ambient humidity of the environment in which the battery pack is applied. By collecting the battery subpackaging application humidity, it is convenient to determine the assembly and use environment of the battery pack. The preset application humidity is the ambient humidity in which the battery pack is to be used. By adjusting the battery subpackaging application humidity with the preset application humidity, the ambient humidity of the battery pack and the specified ambient humidity are obtained by the least square difference, so as to reduce the error of the subpackaging humidity difference. The sub-packaging humidity difference is greater than or equal to the preset humidity difference, indicating that the humidity of the environment in which the battery pack is used is too high, that is, the environment in which the battery pack is to be used is an aquatic environment, for example, the battery pack is used on an unmanned boat. At this time, by sending a distributed sub-packaging enable signal to the battery assembly system, the modules of the battery pack are installed in a distributed manner, which facilitates the distributed design of the battery modules of the battery pack, so that the overall center of gravity of the battery pack remains balanced, thereby reducing the impact of the center of gravity deviation on the battery pack application equipment.

[0045] In another embodiment, when the humidity difference of the sub-packaging is less than the preset humidity difference, a distributed sub-packaging disabling signal is sent to the battery assembly system so that the modules of the battery pack can be installed in an intensive manner. In this way, when the battery pack is used in an environment where the impact on the center of gravity is not obvious, it can be arranged as centrally as possible to improve assembly efficiency.

[0046] In one of the embodiments, the obtaining of the subpackaging environmental parameters of the battery pack includes: obtaining the battery subpackaging application altitude of the battery pack. In this embodiment, the subpackaging environmental parameters are the battery assembly application environment data of the battery pack, that is, the subpackaging environmental parameters are the use environment of the battery pack, that is, the subpackaging environmental parameters correspond to the working environment of the battery pack. By collecting the subpackaging environmental parameters, it is convenient to determine the assembly condition of the battery pack in the environment to be applied. The subpackaging environmental parameters include the battery subpackaging application altitude of the battery pack, and the battery subpackaging application altitude is the environmental altitude of the environment in which the battery pack is applied. By collecting the battery subpackaging application altitude, it is convenient to determine the assembly and use environment of the battery pack.

[0047] Further, the subpackaging environmental parameters and the preset environmental parameters are subjected to a package-by-package adjustment process to obtain a subpackaging adjustment amount, including: obtaining the adjustment of the battery subpackaging application altitude and the preset application altitude to obtain the subpackaging altitude difference. In the present embodiment, the subpackaging environmental parameters are the battery assembly application environment data of the battery pack, that is, the subpackaging environmental parameters are the use environment of the battery pack, that is, the subpackaging environmental parameters correspond to the working environment of the battery pack. By collecting the subpackaging environmental parameters, it is convenient to determine the assembly condition of the battery pack in the environment to be applied. The preset environmental parameters are the battery assembly reference application environment data of the battery pack, that is, the preset environmental parameters are the standard use environment of the battery pack, that is, the preset environmental parameters correspond to the specified working environment of the battery pack. By performing a package-by-package adjustment process on the subpackaging environmental parameters and the preset environmental parameters, it is convenient to determine the differences in the application environment of the battery pack. The subpackaging environmental parameters include the battery subpackaging application altitude of the battery pack. The battery subpackaging application altitude is the environmental altitude of the environment in which the battery pack is used. By collecting the battery subpackaging application altitude, it is convenient to determine the assembly and use environment of the battery pack. The preset application altitude is the environmental altitude in which the battery pack is to be used. By adjusting the battery subpackaging application altitude with the preset application altitude, the least square difference between the environmental altitude of the battery pack and the specified environmental altitude is obtained to reduce the error of the subpackaging altitude difference.

[0048] Furthermore, the distribution sub-assembly disabling signal is sent to the battery assembly system according to the sub-assembly adjustment amount to adjust the assembly mode of each module of the battery pack in the energy storage cabinet, including: detecting whether the sub-assembly altitude difference is greater than or equal to the preset altitude difference; when the sub-assembly altitude difference is less than the preset altitude difference, a distribution sub-assembly disabling signal is sent to the battery assembly system so that each module of the battery pack is installed in an intensive manner. In this embodiment, the sub-assembly adjustment amount is obtained based on the sub-assembly environmental parameters and the preset environmental parameters, and the sub-assembly environmental parameters are the battery assembly application environment data of the battery pack, that is, the sub-assembly environmental parameters are the use environment of the battery pack, that is, the sub-assembly environmental parameters correspond to the working environment of the battery pack. By collecting the sub-assembly environmental parameters, it is convenient to determine the assembly status of the battery pack in the environment to be applied. The preset environmental parameters are the battery assembly reference application environment data of the battery pack, that is, the preset environmental parameters are the standard use environment of the battery pack, that is, the preset environmental parameters correspond to the specified working environment of the battery pack. By processing the package group packaging adjustment of the subpackaging environmental parameters and the preset environmental parameters, it is convenient to determine the differences in the application environment of the battery pack. After obtaining the subpackaging adjustment amount, the degree of difference in the application environment of the battery pack can be determined, which is convenient for controlling the assembly method of each module of the battery pack so that the distribution of the battery pack adapts to the application environment, thereby reducing the difficulty and cost of assembly. The subpackaging environmental parameters include the battery subpackaging application altitude of the battery pack. The battery subpackaging application altitude is the environmental altitude of the application environment of the battery pack. By collecting the battery subpackaging application altitude, it is convenient to determine the assembly and use environment of the battery pack. The preset application altitude is the environmental altitude where the battery pack is to be used. By adjusting the battery subpackaging application altitude with the preset application altitude, the least square difference between the environmental altitude of the battery pack and the specified environmental altitude is obtained to reduce the error of the subpackaging altitude difference. The subpackaging altitude difference is less than the preset altitude difference, indicating that the battery pack is used in an environment with a low altitude, that is, the battery pack is to be used in a low altitude environment. For example, the battery pack is used in a heavy-load transport drone in a plain area. At this time, a distributed subpackaging disabling signal is sent to the battery assembly system so that the modules of the battery pack are installed in an intensive manner. In this way, when the battery pack is used in an environment where the altitude is not obvious and the external environment temperature difference is not large, the modules can be installed as centrally as possible to improve assembly efficiency.

[0049] In another embodiment, when the subpackaging altitude difference is greater than or equal to the preset altitude difference, it indicates that the altitude of the environment in which the battery pack is used is too high, that is, it indicates that the environment in which the battery pack is to be used is a high mountain environment. For example, the battery pack is used in a heavy-load transport drone in a mountainous area. At this time, a distributed subpackaging enable signal is sent to the battery assembly system so that each module of the battery pack is installed in a distributed manner, which facilitates the distributed design of each battery module of the battery pack, so that the contact area between each module of the battery pack and the environment is increased, thereby increasing the heat exchange rate of the battery pack, and then maintaining a relative balance in the temperature difference between the modules of the battery pack, while also improving the temperature balance between the battery pack and the environmental sub-components.

[0050] During the actual operation of the battery pack, that is, rapid discharge, the battery pack is formed by connecting battery modules in series and parallel. Batch battery modules are usually stored in an energy storage cabinet. During the discharge output process of a large number of battery modules, the temperature of each battery module in the whole box will change according to the discharge output current adjustment. Due to the space limited in the energy storage cabinet, the batch battery modules accumulate heat in the closed box and there is a risk of thermal runaway and fire, which will seriously lead to uncontrollable fire.

[0051] In order to effectively reduce the probability of thermal runaway of the battery pack during application, the distributed subassembly failure signal is sent to the battery assembly system according to the subassembly adjustment amount to adjust the assembly mode of each module of the battery pack in the energy storage cabinet, and then the following steps are also included:

[0052] Get the built-in separation volume of the overheated battery module of the battery pack;

[0053] Detecting whether the built-in separation amount of the overheated battery module is less than or equal to a preset separation amount;

[0054] When the internal separation amount of the overheated battery module is less than or equal to the preset separation amount, an internal reduction and edge increase power signal is sent to the battery assembly system.

[0055] In this embodiment, the built-in separation amount of the overheated battery module is the number of battery packs spaced apart between the overheated battery modules located in the middle area of ​​the energy storage cabinet. Specifically, the built-in separation amount of the overheated battery module is the median value of the number of battery packs spaced apart between the overheated battery modules located in the middle area of ​​the energy storage cabinet. By collecting the built-in separation amount of the overheated battery modules, it is convenient to determine the density between the overheated battery modules located in the middle area of ​​the energy storage cabinet. The built-in separation amount of the overheated battery modules is less than or equal to the preset separation amount, indicating that the number of intervals between the overheated battery modules located in the middle area of ​​the energy storage cabinet is too large, that is, it indicates that the density of the overheated battery modules located in the middle area of ​​the energy storage cabinet is too high, that is, it indicates that the battery modules located in the middle area of ​​the energy storage cabinet are prone to thermal runaway and fire risks. At this time, by sending an inner reduction and edge increase power signal to the battery assembly system, the discharge output current of the battery modules located in the middle area of ​​the energy storage cabinet is reduced, and the discharge output current of the battery modules located in the edge area of ​​the energy storage cabinet is increased, so that the less discharged power of the battery modules located in the middle area of ​​the energy storage cabinet is balanced through the more discharged power of the battery modules located in the edge area of ​​the energy storage cabinet, so that the overall temperature in the energy storage cabinet is kept consistent while ensuring that the remaining power of each battery module after final discharge meets the normal working requirements.

[0056] Furthermore, the detecting whether the internal separation amount of the overheated battery module is less than or equal to a preset separation amount further includes:

[0057] When the internal partition amount of the overheated battery module is greater than the preset partition amount, obtaining the internal field space occupancy ratio of the overheated battery module of the battery pack;

[0058] Detecting whether the space occupancy ratio of the over-temperature battery module is greater than or equal to a preset occupancy ratio;

[0059] When the space occupancy ratio of the over-temperature battery module is greater than or equal to the preset occupancy ratio, an inner shrinkage delay time signal is sent to the battery assembly system.

[0060] In this embodiment, the built-in separation amount of the overheated battery module is greater than the preset separation amount, indicating that the number of battery packs spaced between the overheated battery modules located in the middle area of ​​the energy storage cabinet is too small, that is, the density of the overheated battery modules located in the middle area of ​​the energy storage cabinet is too low, that is, the overheating risk caused by the overheated battery modules in the middle of the energy storage cabinet is relatively low. At this time, by collecting the internal field space occupancy ratio of the overheated battery modules of the battery pack, the distribution ratio of the overheated battery modules in the middle of the energy storage cabinet is determined. Specifically, the internal field space occupancy ratio of the overheated battery modules is the ratio of the space size of the overheated battery modules in the middle area of ​​the energy storage cabinet. The overheated battery module inner field space occupancy ratio is greater than or equal to the preset occupancy ratio, indicating that the overheated battery modules occupy too much space in the middle area of ​​the energy storage cabinet, that is, the number of overheated battery modules in the middle area of ​​the energy storage cabinet exceeds the number of overheated battery modules in the edge area of ​​the energy storage cabinet. At this time, by sending an inner shrinkage delay time signal to the battery assembly system, the discharge time of the overheated battery modules in the middle area of ​​the energy storage cabinet is shortened, and the discharge time of the overheated battery modules in the edge area of ​​the energy storage cabinet is extended. Under the condition of ensuring that the remaining power of each battery module after final discharge meets the normal working requirements, the risk of thermal runaway is further avoided.

[0061] In another embodiment, when the field space occupancy ratio of the over-temperature battery module is less than the preset occupancy ratio, the current uniform discharge time and discharge current of each battery module are maintained.

[0062] The above-mentioned various preset variables are all set in the database for timely retrieval, and different preset variables are placed in different storage units, that is, in different storage stacks. Moreover, the built-in partition volume of the overheated battery module and the field space occupancy ratio of the overheated battery module can be collected through corresponding detectors, for example, through the infrared imager and counter in the sub-packet collection module.

[0063] In one of the embodiments, the present disclosure also relates to a distributed installation monitoring device for a high-string battery pack, comprising: a subpackaging collection module, a package group processing module and a subpackaging control module; the subpackaging collection module is used to obtain the subpackaging environmental parameters of the battery pack; the package group processing module is used to perform package group packaging adjustment processing on the subpackaging environmental parameters and preset environmental parameters to obtain the subpackaging adjustment amount; the subpackaging control module is used to send a distributed subpackaging failure signal to the battery assembly system according to the subpackaging adjustment amount to adjust the assembly mode of each module of the battery pack in the energy storage cabinet.

[0064] In this embodiment, after the subpackaging acquisition module collects the subpackaging environmental parameters, the battery assembly application environment state of the battery pack is determined, and then the package group processing module compares the subpackaging environmental parameters with the standard environmental parameters to facilitate determining the difference between the current battery assembly application environment state of the battery pack and the specified application environment state. Finally, the subpackaging control module optimizes and adjusts the assembly mode of the battery pack according to the above difference value, so as to facilitate the adjustment of the installation method of each module of the battery pack to select an assembly method suitable for the current application environment, thereby effectively reducing the difficulty and cost of battery pack assembly.

[0065] In one embodiment, a computer device is provided. The computer device may be a server, and its internal structure diagram may be as follows: Figure 2 As shown. The computer device includes a processor, a memory and a network interface connected via a system bus. Among them, the processor of the computer device is used to provide computing and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system, a computer program and a database. The internal memory provides an environment for the operation of the operating system and the computer program in the non-volatile storage medium. The database of the computer device is used to store data such as battery pack configuration status parameters, battery pack configuration screening and adjustment, and battery pack batch configuration start and close signals.
