Description

Method and apparatus for monitoring battery fluid injection facilities

[0001] The present invention relates to a method and apparatus for monitoring a battery injection facility, and specifically, to a method and apparatus for monitoring the type, quality, etc. of the electrolyte and DMC included in the injection facility.

[0002]

[0003] To improve battery quality, it is important to maintain consistent quality of the electrolyte and DMC in the battery injection facility. However, due to the nature of the injection facility, it is impossible to inspect the interior of the electrolyte tank storing the electrolyte and the DMC clean vessel storing the DMC, which makes it impossible to detect abnormalities in the electrolyte and DMC at an early stage. In other words, unless the electrolyte tank and the DMC clean vessel are disassembled to allow inspection of their interiors, it is impossible to determine what quality changes are occurring internally.

[0047] FIG. 1 is a drawing showing an example of a main electrolyte tank (110) and a sub-electrolyte tank (120) equipped with an ion conductivity sensor according to one embodiment of the present invention. According to one embodiment, the main electrolyte tank (110) and the sub-electrolyte tank (120) can be used to store an electrolyte to be injected into a battery (e.g., a cylindrical battery). For example, the electrolyte stored in the main electrolyte tank (110) and the sub-electrolyte tank (120) can be injected into a battery cell using a pallet device. Additionally, the pallet device used for electrolyte injection can be cleaned using an electrolyte organic solvent such as DMC (dimethyl carbonate).

[0048] According to one embodiment, an ion conductivity sensor may be used to monitor the quality of the electrolyte stored in the main electrolyte tank (110) and the sub-electrolyte tank (120). For example, a first ion conductivity sensor (112) may be provided in the main electrolyte tank (110), and a second ion conductivity sensor (114) may be provided in the sub-electrolyte tank (120). An abnormality in the quality of the electrolyte may be monitored using the ion conductivity values ​​measured by the first ion conductivity sensor (112) and the second ion conductivity sensor (114).

[0049] According to one embodiment, if the first ion conductivity value measured by the first ion conductivity sensor (112) is greater than or equal to the first reference value, it may be determined that there is a possibility of quality abnormality in the electrolyte contained in the main electrolyte tank (110). In this case, a visual and / or auditory first quality abnormality alarm may be provided to a user, such as an administrator. That is, a user who receives the first quality abnormality alarm can check the condition of the electrolyte in the main electrolyte tank (110).

[0050] According to one embodiment, if the first ion conductivity value measured by the first ion conductivity sensor (112) is greater than or equal to a second reference value which is higher than a first reference value, it may be determined that there is a quality defect in the electrolyte contained in the main electrolyte tank (110). In this case, a visual and / or auditory secondary quality defect alarm may be provided to a user, such as an administrator. Additionally, the operation of the electrolyte injection facility may be stopped as the secondary quality defect alarm is provided.

[0051] Additionally or alternatively, if the second ion conductivity value measured by the second ion conductivity sensor (122) is greater than or equal to the first reference value, it may be determined that there is a possibility of quality abnormality in the electrolyte contained in the sub-electrolyte tank (120). In this case, a visual and / or auditory primary quality abnormality alarm may be provided to a user, such as an administrator. Here, the primary quality abnormality alarm may include information about the object where there is a possibility of quality abnormality (e.g., main electrolyte tank (110), sub-electrolyte tank (120), etc.).

[0052] Likewise, if the second ion conductivity value measured by the second ion conductivity sensor (122) is higher than the first reference value, it may be determined that there is a quality defect in the electrolyte contained in the sub-electrolyte tank (120). In this case, a visual and / or auditory secondary quality defect alarm may be provided to a user, such as an administrator. Additionally, the operation of the electrolyte injection facility may be stopped as the secondary quality defect alarm is provided.

[0053] Additionally or alternatively, whether the type of electrolyte present in the main electrolyte tank (110) and the sub-electrolyte tank (120) is the same can be monitored. For example, a difference value between a first ion conductivity value and a second ion conductivity value can be calculated, and if the difference value is greater than or equal to a first threshold, it can be determined that there is a possibility that the type of electrolyte present in the main electrolyte tank (110) and the sub-electrolyte tank (120) is different. In this case, a visual and / or auditory primary type or higher alarm can be provided to a user, such as an administrator.

[0054] According to one embodiment, if the difference between the first ion conductivity value and the second ion conductivity value is greater than or equal to a second threshold value which is higher than a first threshold value, it may be determined that the types of electrolytes present in the main electrolyte tank (110) and the sub-electrolyte tank (120) are different. In this case, a visual and / or auditory alarm of a second type or higher may be provided to a user, such as an administrator. Additionally, the operation of the electrolyte injection facility may be stopped as the alarm of a second type or higher is provided.

[0055] Although only the main electrolyte tank (110) and the sub-electrolyte tank (120) are shown in FIG. 1, a third ion conductivity sensor may also be provided on a DMC clean vessel for cleaning the pallet device after injecting the electrolyte. Here, the DMC clean vessel may refer to a device used to clean the electrolyte remaining in the pallet device using an electrolyte organic solvent such as dimethyl carbonate (DMC), ethyl methyl carbonate (EMC), di ethyl carbonate (DEC), or ethylene carbonate (EC).

[0056] According to one embodiment, the electrolyte organic solvent contained in the DMC clean vessel may change in quality as it is continuously mixed with the electrolyte. To check the quality of the electrolyte organic solvent within the DMC clean vessel, a third ion conductivity sensor may be provided on the DMC clean vessel, and the quality of the electrolyte organic solvent may be monitored using the third ion conductivity value obtained from the third ion conductivity sensor.

[0057] According to one embodiment, if the third ion conductivity value measured by the third ion conductivity sensor is greater than or equal to the third reference value, it may be determined that there is a possibility of quality abnormality in the organic solvent of the electrolyte contained in the DMC clean vessel. In this case, a visual and / or auditory primary DMC abnormality alarm may be provided to a user, such as an administrator. That is, a user who receives the primary DMC abnormality alarm can check the condition of the organic solvent of the electrolyte inside the DMC clean vessel.

[0058] In addition, if a primary DMC or higher alarm is provided, the replacement cycle of the electrolyte organic solvent, such as the DMC, can be calculated. In this case, the replacement cycle of the electrolyte organic solvent can be calculated based on the ionic conductivity value of the normal electrolyte organic solvent and the ionic conductivity value of the electrolyte organic solvent requiring replacement. For example, the period during which the ionic conductivity value of the normal electrolyte organic solvent changes to a third ionic conductivity value can be calculated, and based on the calculated period, the period during which the third ionic conductivity value changes to the ionic conductivity value of the electrolyte organic solvent requiring replacement can be predicted. In this case, the replacement cycle can be calculated according to the predicted period.

[0059] According to one embodiment, if the third ion conductivity value measured by the third ion conductivity sensor is greater than or equal to a fourth reference value which is higher than a third reference value, it may be determined that there is a quality defect in the DMC contained in the DMC clean vessel. In this case, a visual and / or auditory secondary DMC defect alarm may be provided to a user, such as an administrator. Additionally, the operation of the electrolyte injection facility may be stopped as the secondary DMC defect alarm is provided.

[0060] In FIG. 1, quality abnormality judgment, type abnormality judgment, etc., within the main electrolyte tank (110), sub-electrolyte tank (120) and / or DMC clean vessel are described as being performed individually, but are not limited thereto, and each abnormality judgment may be performed sequentially. With such a configuration, abnormality judgment of the electrolyte, etc., can be easily performed using an injection facility equipped with an ion conductivity sensor and a unique algorithm for processing ion conductivity values, and the quality of the battery and / or battery cell manufactured accordingly can be effectively improved.

[0061] FIG. 2 is a block diagram illustrating an example in which a computing device (200) according to one embodiment of the present invention is connected to a user terminal (210) and an electrolyte injection facility. According to one embodiment, the computing device (200) may refer to a device that communicates with the user terminal (210), main electrolyte tank (110), sub electrolyte tank (120), DMC clean vessel (220), IBC tank (230), etc., processes transmitted and received data, and performs abnormal monitoring of the electrolyte and / or electrolyte organic solvent. Additionally, the user terminal (210) may refer to a terminal of a manager who manages the electrolyte injection facility.

[0062] According to one embodiment, an ion conductivity sensor for measuring or verifying the ion conductivity value of the electrolyte and / or the electrolyte organic solvent may be provided in the main electrolyte tank (110), sub-electrolyte tank (120), DMC clean vessel (220), IBC tank (230), etc. For example, the ion conductivity sensor may be provided at a mounting point at the water level sensor LL and at a point 3 mm away, but is not limited thereto.

[0063] The computing device (200) may receive reference values ​​for ion conductivity of the main electrolyte tank (110), sub-electrolyte tank (120), DMC clean vessel (220), IBC tank (230), etc. from the user terminal (210). For example, the computing device (200) may receive a first reference value and a second reference value associated with the electrolyte from the user terminal (210), or receive a third reference value and a fourth reference value associated with an electrolyte organic solvent such as DMC. Additionally, the computing device (200) may receive a first threshold and a second threshold representing the difference in ion conductivity values ​​between the main electrolyte tank (110) and the sub-electrolyte tank (120).

[0064] The computing device (200) can monitor quality abnormalities, type abnormalities, etc. of the electrolyte and / or electrolyte organic solvent based on input reference values ​​and / or thresholds. For example, the computing device (200) can receive ion conductivity values ​​from the main electrolyte tank (110) and the IBC tank (230). In this case, the computing device (200) can compare the ion conductivity values ​​of the main electrolyte tank (110) and the IBC tank (230) to determine whether they are within the threshold. If the difference in ion conductivity values ​​is greater than or equal to the threshold, the computing device (200) can determine that the electrolyte contained in the main electrolyte tank (110) and the IBC tank (230) is of a different type. If it is determined that the types are different in this way, the computing device (200) can send a message to the user terminal (210) that the electrolyte cannot be transferred.

[0065] When it is determined that the electrolyte contained in the main electrolyte tank (110) and the IBC tank (230) is of the same type, the computing device (200) can compare the ion conductivity value of the main electrolyte tank (110) with a first reference value and a second reference value. If the ion conductivity value is greater than or equal to the first reference value or less than the second reference value, a first quality abnormality alarm can be provided to the user terminal (210), etc., and if the ion conductivity value is greater than or equal to the second reference value, a second quality abnormality alarm can be provided to the user terminal (210), etc.

[0066] When the ion conductivity value of the main electrolyte tank (110) is less than a first reference value, the computing device (200) can compare the difference between the ion conductivity value of the main electrolyte tank (110) and the ion conductivity value of the sub-electrolyte tank (120) with a first threshold and a second threshold. If the difference value is greater than or equal to the first threshold and less than the second threshold, a first type of alarm is provided to the user terminal (210), etc., and if the difference value is greater than or equal to the second threshold, a second type of alarm is provided to the user terminal (210), etc.

[0067] If the difference value is less than the first threshold, the computing device (200) can compare the ion conductivity value of the sub-electrolyte tank (120) with the first reference value and the second reference value. If the ion conductivity value is greater than or equal to the first reference value but less than the second reference value, a first quality abnormality alarm can be provided to the user terminal (210), etc., and if the ion conductivity value is greater than or equal to the second reference value, a second quality abnormality alarm can be provided to the user terminal (210), etc.

[0068] Additionally or alternatively, the computing device (200) can compare the ion conductivity value of the DMC clean vessel (220) with a third reference value and a fourth reference value. If the ion conductivity value is greater than or equal to the third reference value or less than the fourth reference value, a first DMC abnormality alarm can be provided to the user terminal (210), etc., and if the ion conductivity value is greater than or equal to the fourth reference value, a second DMC abnormality alarm can be provided to the user terminal (210), etc. If there are no abnormalities in the monitoring results, the injection facility can be operated normally, and the user can receive and verify immediate monitoring information via the user terminal (210).

[0069] FIG. 3 is a diagram illustrating an example of a method (300) for monitoring quality abnormalities of an electrolyte tank according to an embodiment of the present invention. The method (300) for monitoring quality abnormalities of an electrolyte tank may be performed by at least one processor (e.g., at least one processor of a computing device).

[0070] According to one embodiment, the processor can determine whether the received ion conductivity value (a first ion conductivity value or a second ion conductivity value) is greater than or equal to a first reference value (S320). Here, the first reference value may be set or input from a user terminal. Additionally, if the processor determines that the ion conductivity value is greater than or equal to the first reference value, it may provide a first quality abnormality alarm (S330).

[0071] According to one embodiment, the processor can determine whether the received ion conductivity value is greater than or equal to a second reference value (S340). Here, the second reference value is set or input by the user terminal and may be higher than the first reference value. Additionally, if the processor determines that the ion conductivity value is greater than or equal to the second reference value, it may provide a second quality abnormality alarm (S350).

[0072] In this way, when a secondary quality abnormality alarm is provided, the processor can determine whether the electrolyte injection facility is in operation. Then, if the electrolyte injection facility is in operation, the processor can stop the operation of the electrolyte injection facility (S360). In this case, the user who received the secondary quality abnormality alarm can perform the replacement of the electrolyte contained in the main electrolyte tank or the sub-electrolyte tank.

The method for monitoring an anomaly in the type of an electrolyte tank (400) may be performed by at least one processor (e.g., at least one processor of a computing device). The method for monitoring an anomaly in the type of an electrolyte tank (400) may be initiated by the processor calculating a difference value between a first ion conductivity value of a main electrolyte tank and a second ion conductivity value of a sub-electrolyte tank (S410).

[0074] According to one embodiment, the processor can determine whether the calculated difference value is greater than or equal to a first threshold (S420). Here, the first threshold may be set or input from a user terminal. Additionally, if the processor determines that the difference value is greater than or equal to the first threshold, it may provide a first type or higher alarm (S430).

[0075] According to one embodiment, the processor can determine whether the calculated difference value is greater than or equal to a second threshold (S440). Here, the second threshold is set or input by the user terminal and may be higher than the first threshold. If it is determined that the difference value is greater than or equal to the second threshold, the processor may provide a second type of alarm (S450).

[0076] In this way, when a second or higher type of alarm is provided, the processor can determine whether the electrolyte injection facility is in operation. Then, if the electrolyte injection facility is in operation, the processor can stop the operation of the electrolyte injection facility (S460). In this case, the user who received the second or higher type of alarm can perform the replacement of the electrolyte contained in the main electrolyte tank or the sub-electrolyte tank.

[0077] FIG. 5 is a diagram illustrating an example of a DMC clean vessel monitoring method (500) according to an embodiment of the present invention. The DMC clean vessel monitoring method (500) may be performed by at least one processor (e.g., at least one processor of a computing device). The DMC clean vessel monitoring method (500) may be initiated by the processor receiving a third ion conductivity value of the DMC based on a third ion conductivity sensor provided in the DMC clean vessel containing the DMC (S510).

[0078] According to one embodiment, the processor can determine whether the received third ion conductivity value is greater than or equal to a third reference value (S520). Here, the third reference value may be set or input from a user terminal. Additionally, if the processor determines that the third ion conductivity value is greater than or equal to the third reference value, it may provide a first DMC abnormality alarm (S530).

[0079] According to one embodiment, the processor can determine whether the received third ion conductivity value is greater than or equal to a fourth reference value (S540). Here, the fourth reference value is set or input by the user terminal and may be higher than the third reference value. Additionally, if the processor determines that the third ion conductivity value is greater than or equal to the fourth reference value, it may provide a second DMC abnormality alarm (S550).

[0080] In this way, when a secondary DMC or higher alarm is provided, the processor can determine whether the electrolyte injection facility is in operation. Then, if the electrolyte injection facility is in operation, the processor can stop the operation of the electrolyte injection facility (S560). In this case, the user who received the secondary DMC or higher alarm can perform the replacement of the DMC included in the DMC clean vessel.
