Description

Technical Field

[0001] This utility model relates to the field of battery production technology, specifically to a battery formation workshop. Background Technology

[0002] A typical battery formation workshop includes a high-temperature workshop and an ambient-temperature corridor, separated by a partition wall. Formation equipment includes electrically connected battery cabinets and power supply cabinets. Each battery cabinet has a feed door on one side for loading and unloading batteries. To meet the environmental requirements of battery formation, the battery cabinets are placed in the high-temperature workshop, while the power supply cabinets are typically placed in the ambient-temperature corridor to ensure their proper operation. The battery cabinets and power supply cabinets are arranged separately, with multiple battery cabinets located within the high-temperature workshop. The power supply cabinets are situated in the ambient-temperature corridor, thus providing the necessary manufacturing environment for formation.

[0003] Meanwhile, to facilitate the maintenance and repair of the battery cabinets, maintenance doors need to be installed on each cabinet. These doors are typically located on the side opposite the feed door, i.e., near the side wall of the high-temperature workshop. A maintenance passageway must also be provided within the high-temperature workshop to allow for the opening and closing of the maintenance doors and for personnel to perform maintenance operations. This results in a larger space in the high-temperature workshop and higher energy consumption for maintaining its temperature. Utility Model Content

[0004] In view of this, the present invention provides a battery formation workshop to solve the problems of large space and high energy consumption in the high-temperature workshops of the related technologies, which set up maintenance channels in the high-temperature workshops.

[0005] This utility model provides a battery formation workshop, including:

[0006] Workshop 1;

[0007] The second workshop is separated from the first workshop by a partition;

[0008] The chemical storage unit includes an electrically connected battery cabinet and a power supply cabinet. The battery cabinet is embedded in the partition and located in the first workshop. The side of the battery cabinet closest to the second workshop has an openable maintenance door. The power supply cabinet is located in the second workshop.

[0009] Beneficial effects: Compared with related technologies that place maintenance access channels in high-temperature workshops, the battery formation workshop provided by this technology separates the first workshop and the second workshop with a partition. The battery cabinet is embedded in the partition and located in the high-temperature first workshop, while the power cabinet is located in the normal-temperature second workshop. The maintenance door of the battery cabinet is located on the side closer to the second workshop. When the battery cabinet needs to be maintained, the work can be carried out only on the side of the second workshop, which can eliminate the maintenance access channel in the first workshop, save the space in the first workshop, and reduce the total space of the first workshop. This reduces the energy consumption required to heat the first workshop, saves energy, and has lower operating costs. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] The following is combined with Figures 1 to 4 The following describes embodiments of the present invention.

[0020] According to an embodiment of the present invention, in a first aspect, as follows: Figure 1 As shown, a battery formation workshop is provided, including a first workshop 1, a second workshop 2, and a formation storage unit 4. The second workshop 2 is separated from the first workshop 1 by a partition 3. The formation storage unit 4 includes a battery cabinet 401 and a power supply cabinet 402 that are electrically connected. The battery cabinet 401 is embedded in the partition 3 and located in the first workshop 1. The side of the battery cabinet 401 closest to the second workshop 2 has an openable maintenance door (not shown in the figure). The power supply cabinet 402 is located in the second workshop 2.

[0021] Compared to related technologies that place the maintenance passage 6 in a high-temperature workshop, the battery formation workshop provided by this technology separates the first workshop 1 and the second workshop 2 by a partition 3. The battery cabinet 401 is embedded in the partition 3 and located in the high-temperature first workshop 1, while the power cabinet 402 is located in the normal-temperature second workshop 2. The maintenance door of the battery cabinet 401 is located on the side closer to the second workshop 2. When the battery cabinet 401 needs to be maintained, the maintenance door is opened, and the work can be carried out only on the side of the second workshop 2. This eliminates the need for the maintenance passage 6 in the first workshop 1, saves the space used in the first workshop 1, and makes the total space of the first workshop 1 relatively smaller, which greatly improves the space utilization rate, thereby reducing the energy consumption required to heat the first workshop 1, saving energy, and reducing the operating cost.

[0022] Specifically, Workshop 1 is a high-temperature workshop used for battery production. Workshop 2 is an ambient-temperature workshop. A maintenance door is provided to facilitate maintenance work on battery cabinet 401 by staff in Workshop 2. Since the maintenance door is located on the side of battery cabinet 401 closest to Workshop 2, it also reduces the disruption to the dew point environment of battery cabinet 401, which is beneficial for subsequent accurate and reliable measurement of the ambient dew point temperature inside battery cabinet 401.

[0023] In some embodiments, the periphery of the battery cabinet 401 is sealed to the partition 3. This arrangement prevents the first workshop 1 and the second workshop 2 from communicating at the connection between the battery cabinet 401 and the partition 3, effectively preventing heat from the first workshop 1 from escaping from the connection between the battery cabinet 401 and the partition 3, thereby further reducing energy consumption and operating costs.

[0024] Furthermore, in some embodiments, such as Figure 2 and Figure 3 As shown, a heat insulation layer 5 is filled at the connection between the battery cabinet 401 and the partition 3 to fill the gap between them. By filling the gap between the battery cabinet 401 and the partition 3 with the heat insulation layer 5, it is possible to further prevent the first workshop 1 and the second workshop 2 from connecting at the connection gap between the battery cabinet 401 and the partition 3. The heat insulation layer 5 can be made of conventional heat insulation materials such as polystyrene particle foam or polystyrene board.

[0025] In some embodiments, the maintenance door is made of an insulation board, which includes at least one of aluminum silicate fiberboard and fiberglass board. The overall thermal conductivity of the maintenance door is less than 1.0. By using an insulation board to make the maintenance door, a heat insulation effect is achieved, which can prevent the heat of the battery cabinet 401 from escaping from the maintenance door, thereby effectively maintaining the temperature of the battery cabinet 401.

[0026] Furthermore, in some embodiments, the outer surface of the insulation panel is covered with a protective layer. This protective layer, used to protect the insulation panel, can be a metal layer, such as sheet metal.

[0027] In some embodiments, such as Figure 3 As shown, the battery cabinet 401 is located on one side of the first workshop 1 and is also equipped with an openable feed door 403. The feed door 403 is used for loading and unloading the battery cabinet 401, that is, after opening the feed door 403, batteries can be transported into or removed from the battery cabinet 401.

[0028] Furthermore, in some embodiments, the maintenance door and the feed door 403 are interlocked. Interlocking means that when one is open, the other is closed; they will not open simultaneously.

[0029] Specifically, when maintenance personnel open the maintenance door, the feed door 403 is locked to prevent communication between Workshop 1 and Workshop 2, thus ensuring the safety of maintenance personnel. When the feed door 403 is open, the maintenance door remains locked to prevent communication between the high-temperature environments of Workshop 1 and Workshop 2, which could affect the ambient dew point temperature and thus ensure product processing quality.

[0030] By interlocking the feed door 403 and the maintenance door, it is ensured that the feed door 403 and the maintenance door will not be opened at the same time. This ensures the safety of maintenance personnel during maintenance and maintains the stability of the dew point temperature in the high-temperature environment of Workshop 1 during production, thus preventing battery quality problems and the outflow of unqualified products due to substandard dew point.

[0031] It should be noted that this embodiment of the utility model does not restrict the arrangement of the formation storage positions 4. Any existing arrangement can be selected as needed, such as row arrangement, matrix arrangement, etc.

[0032] In some embodiments, at least two formation storage locations 4 are arranged side by side along the length of the first workshop 1. The number of formation storage locations 4 can be selected as two, three, or more as needed, and this embodiment of the present invention does not limit this.

[0033] Specifically, the length direction of the first workshop 1 is as follows: Figure 1 As shown by arrow L in the diagram, the width direction of the first workshop 1 is as follows: Figure 1 As indicated by arrow W in the diagram. The length direction of the second workshop 2 is the same as the length direction of the first workshop 1, and the width direction of the second workshop 2 is the same as the width direction of the first workshop 1.

[0034] In some embodiments, such as Figure 1 As shown, multiple formation storage locations 4 are located on both sides of the width of the first workshop 1. This arrangement can better balance the temperature distribution of each battery cabinet 401, ensuring that each battery cabinet 401 in the formation storage location 4 can obtain a stable high-temperature environment and avoid the impact of sudden temperature changes on battery performance.

[0035] It should be noted that multiple battery cabinets 401 and power supply cabinets 402 can be optionally installed in each formation storage location 4 as needed. For example, such as Figure 1 As shown, each formation storage location 4 has two battery cabinets 401 and two power supply cabinets 402, with the two battery cabinets 401 and two power supply cabinets 402 arranged side by side in each location. This allows for the simultaneous processing of more batteries, significantly improving production efficiency. The two battery cabinets 401 and two power supply cabinets 402 can operate independently without affecting each other.

[0036] Furthermore, if multiple formation storage locations 4 are set up, such as Figure 1 As shown, multiple battery cabinets 401 are respectively located on both sides of the width direction of the first workshop 1, and multiple power supply cabinets 402 are respectively located on both sides of the width direction of the second workshop 2. This makes the layout of the entire formation storage area 4 more compact and saves space.

[0037] In some embodiments, such as Figure 1As shown, multiple battery cabinets 401 and multiple power supply cabinets 402 are arranged opposite each other, and a maintenance passage 6 is formed between the pairs of battery cabinets 401 and power supply cabinets 402. The maintenance passage 6 is located between the battery cabinets 401 and power supply cabinets 402, that is, in the second workshop 2 at room temperature, without occupying the space of the first workshop 1, thus reducing the volume of the first workshop 1 and reducing energy consumption.

[0038] According to an embodiment of the present invention, in a second aspect, as follows: Figure 4 As shown, an environmental dew point measurement and control system is also provided for measuring and controlling the environmental dew point temperature in the battery formation workshop in the above embodiments. The system includes a dew point meter 10, a data transmission module 20, and a host computer 30. The dew point meter 10 measures the environmental dew point temperature T1 of the battery cabinet 401; the data transmission module 20 transmits the environmental dew point temperature T1 measured by the dew point meter 10 to the host computer 30; the host computer 30 receives the environmental dew point temperature T1 and compares it with a preset environmental dew point temperature threshold T0. When T1 < T0, the system is determined to be in production mode; when T1 ≥ T0, the system is determined to be in maintenance mode.

[0039] The dew point meter 10 can accurately measure the ambient dew point temperature T1 of the battery cabinet 401, ensuring high data accuracy. Real-time monitoring by the dew point meter 10 allows for timely understanding of changes in the ambient dew point temperature, providing accurate data support for production control.

[0040] The data transmission module 20 is responsible for transmitting the ambient dew point temperature T1 measured by the dew point meter 10 to the host computer 30, ensuring the real-time performance and reliability of the data. Furthermore, the data transmission module 20 can employ wireless or wired methods to ensure the stability and anti-interference capability of data transmission.

[0041] In some specific embodiments, the data transmission module 20 includes a wireless transmitting and receiving module. The wireless transmitting and receiving module enables electrical connection between the modules, reducing the use of cables, avoiding the possibility of interference between cables and moving structures, and reducing the possibility of equipment failure due to cable aging and damage, thus reducing maintenance costs.

[0042] The host computer 30 receives the ambient dew point temperature T1 and compares it with the preset ambient dew point temperature threshold T0. Based on the comparison result, it determines the working status, which is conducive to realizing automatic production control based on ambient dew point temperature.

[0043] By automatically comparing the measured environmental dew point temperature with the preset value through the host computer 30, it is possible to continuously and real-time monitor the environmental dew point temperature in the battery cabinet 401, and quickly resume normal production in the battery cabinet 401 after the environmental dew point temperature meets the production requirements standards, improving production efficiency. By precisely controlling the environmental dew point temperature, it ensures stable environmental conditions during the battery formation process, improving the quality and consistency of the batteries. At the same time, the stable environmental dew point temperature helps to reduce defects during the battery formation process and lower the scrap rate.

[0044] When T1 < T0, it indicates that the environmental dew point temperature is within the safe range and the system is in the production state. This ensures that the environmental conditions during the battery formation process meet the requirements, which is beneficial to improving production quality and efficiency.

[0045] When T1 ≥ T0, it indicates that the environmental dew point temperature exceeds the safe range and the system enters the maintenance state. This can promptly detect and handle environmental problems, avoiding production accidents caused by poor environmental conditions.

[0046] By setting clear production and maintenance states, the system can quickly respond to environmental changes, promptly adjust the production state, and reduce unnecessary downtime. By strictly controlling the environmental dew point temperature, it ensures that the environmental conditions during the battery formation process are always within the optimal range, improving the quality and consistency of the batteries.

[0047] In some embodiments, as Figure 4 shown, the environmental dew point measurement control system further includes a middle computer 40. The middle computer 40 is used to store and process the environmental dew point temperature data measured by the dew point meter 10, control the data transmission module 20 to send the environmental dew point temperature data to the host computer 30, and receive the control instructions feedback by the host computer 30 to generate a detection record form after the storage location is repaired.

[0048] Furthermore, the middle computer 40 can control the data transmission module 20 to transmit the environmental dew point temperature data to the host computer 30 according to a set period.

[0049] Furthermore, the dew point meter 10 is responsible for real-time measuring the environmental dew point temperature inside the battery cabinet 401, converting the environmental dew point temperature into digital information, and transmitting it to the middle computer 40 for storage and processing.

[0050] The data transmission module 20 is also used to be responsible for sending the processed information of the middle computer 40 and receiving the feedback information of the host computer 30.

[0051] The host computer 30 is also used to receive the environmental dew point temperature data and control the interlock of the maintenance state and production state of the formation storage location 4 according to the set "program logic".

[0052] In some embodiments, as Figure 4As shown, the environmental dew point measurement and control system also includes a power supply module 50, which is electrically connected to the dew point meter 10, the data transmission module 20, the intermediate computer 40, and the upper computer 30; the battery cabinet 401 has a power supply port, and the power supply module 50 is adapted to be electrically connected to the power supply port.

[0053] By setting up the power supply module 50, power can be directly drawn from the power supply port of the battery cabinet 401, thereby realizing automatic power supply for the dew point meter 10, the data transmission module 20, the intermediate computer 40 and the upper computer 30.

[0054] In some embodiments, both the feed door 403 and the maintenance door are electrically connected to the host computer 30. The host computer 30 controls the interlocking between the feed door 403 and the maintenance door. In production mode, the host computer 30 controls the feed door 403 to open and the maintenance door to close; in maintenance mode, the host computer 30 controls the feed door 403 to close and the maintenance door to open.

[0055] Specifically, when battery cabinet 401 requires maintenance, the host computer 30 controls the inlet door 403 to close and the maintenance door to open. At this time, the dew point environment inside battery cabinet 401 may be disrupted, the storage area may freeze, and production may be prohibited. After the maintenance of battery cabinet 401 is completed, the maintenance door is closed and the inlet door 403 is opened. At this time, the storage environment still does not meet the production requirements, so the air inside battery cabinet 401 is exchanged with the air in workshop 1, and a dew point meter 10 is placed inside for real-time measurement.

[0056] After the air inside the battery cabinet 401 has been fully exchanged with the air in the first workshop 1, and the humidity and temperature of the environment inside the battery cabinet 401 meet the production requirements, the host computer 30 receives an environmental dew point temperature that meets the production requirements and sends a production permission command, so that the battery cabinet 401 can continue production.

[0057] In some embodiments, the environmental dew point measurement and control system further includes a transport mechanism located within the battery formation workshop. The transport mechanism is communicatively connected to a host computer 30 and controlled by the host computer 30 to transport the dew point meter 10 or a battery carrying the battery to be processed to any battery cabinet 401. The transport mechanism includes a stacker crane.

[0058] By setting up a transport mechanism, the dew point meter 10 can be transported to the corresponding battery cabinet 401 to achieve accurate and reliable measurement of the ambient dew point temperature of the battery cabinet 401.

[0059] Specifically, the transport mechanism can precisely deliver the dew point meter 10 to any battery cabinet 401 according to the instructions of the host computer 30, ensuring that the ambient dew point temperature of each battery cabinet 401 can be accurately measured. Through the mobility of the transport mechanism, the system can achieve comprehensive monitoring of all battery cabinets 401 within the entire battery formation workshop. Compared to traditional wall-mounted dew point meters, this embodiment of the invention, by using a transport mechanism to deliver the dew point meter 10 to the corresponding battery cabinet 401 for measurement, can improve the validity and accuracy of the measurement data.

[0060] It should be noted that the host computer 30 can schedule the transport mechanism in real time as needed to ensure the efficient transfer of the dew point meter 10 between different battery cabinets 401, reducing the need for manual intervention and improving the automation level of the system.

[0061] The control method of the environmental dew point measurement and control system of this utility model embodiment is as follows:

[0062] The host computer 30 operates the system and inputs the information to be tested. The stacker crane transfers the dew point meter 10 to the battery cabinet 401 to be measured. The power module 50 supplies power to the dew point meter 10 through the power port of the battery cabinet 401. The dew point meter 10 measures the ambient dew point temperature inside the battery cabinet 401 and uploads it to the intermediate computer 40. After processing, the control data transmission module 20 transmits the measurement results to the host computer 30, activates the interlock between the feed door 403 and the maintenance door, and confirms whether the battery cabinet 401 can resume production.

[0063] When maintenance is required, the worker opens the maintenance door, at which point the feed door 403 is locked. Upon completion of maintenance, the maintenance door is closed, and the feed door 403 is unlocked. The stacker crane then transports the dew point meter 10 to the feed door 403 of the corresponding battery cabinet 401 and places it inside. Inside the battery cabinet 401, the dew point meter 10 automatically draws power and detects the ambient dew point temperature. The data transmission module 20 uploads the measured ambient dew point temperature data to the host computer 30, which determines whether it meets production standards. If it does, the stacker crane removes the dew point meter 10, and the battery cabinet 401 resumes battery processing.

[0064] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
