Precautions for using battery compartment
During the use of the battery divider cabinet, the following points should be noted:
1、 In terms of safety
Electrical safety:
Ensure that the distribution cabinet is connected to a stable and reliable power source to avoid equipment damage or safety accidents caused by voltage fluctuations or power failures. Before connecting the power supply, check if the power cord is intact and if the plug is secure.
Strictly follow the electrical parameter requirements of the equipment for operation, and do not exceed the rated voltage, current, and other parameters. For example, if the rated voltage of the distribution cabinet is 220V, it must not be connected to a power source higher than 220V.
Regularly check the grounding status of the distribution cabinet to ensure good grounding and prevent leakage and static electricity accumulation. A grounding resistance tester can be used to regularly check the grounding resistance to ensure that it is within a safe range.
Battery safety:
Before installing the battery into the distribution cabinet, check the appearance of the battery for any damage, deformation, leakage, or other issues. If any abnormalities are found in the battery, testing must not be carried out to avoid safety accidents.
Strictly follow the specifications and requirements of the battery for charging and discharging tests, and do not exceed the rated voltage, current, capacity, and other parameters of the battery. For example, for lithium-ion batteries, the charging voltage should not exceed 4.2V and the discharge cut-off voltage should not be lower than 2.5V.
During the testing process, closely monitor the temperature changes of the battery. If the battery temperature is too high, the test should be stopped immediately and appropriate cooling measures should be taken. A temperature sensor can be used to monitor the battery temperature in real time. When the temperature exceeds the set safe value, the capacity divider should automatically stop testing.
Fire and explosion prevention:
The distribution cabinet should be placed in a well ventilated environment to avoid fire or explosion caused by the accumulation of heat and gas generated during battery charging and discharging. Ensure that there is sufficient space around the container for air circulation.
It is strictly prohibited to place flammable and explosive materials such as alcohol, gasoline, lighters, etc. near the container. At the same time, keep the surrounding environment of the container clean and avoid the accumulation of debris.
Equip necessary fire-fighting equipment, such as fire extinguishers, fire sand, etc., and regularly check their effectiveness. Ensure that operators are familiar with the use of fire-fighting equipment so that they can take timely measures in case of a fire.
2、 Operational aspects
Correctly install the battery:
Install the battery correctly onto the testing fixture according to the operating manual of the distribution cabinet. Ensure good contact between the battery and the fixture, without any looseness or poor contact.
When installing the battery, pay attention to the positive and negative directions of the battery and do not connect them in reverse. If the positive and negative terminals of the battery are reversed, it may cause equipment damage or safety accidents.
Set reasonable testing parameters:
According to the specifications and testing requirements of the battery, set the charging and discharging current, voltage, capacity and other parameters of the capacity divider cabinet reasonably. Do not arbitrarily change the test parameters to avoid affecting the test results or damaging the battery.
When setting test parameters, consider the safety performance and service life of the battery. For example, for lithium-ion batteries, the charging current should not be too high to avoid affecting the battery's cycle life; The discharge cut-off voltage should not be too low to avoid over discharging and damaging the battery.
Operating standards:
Operators should receive professional training and be familiar with the operation methods and precautions of the container. During the operation process, strictly follow the operation manual and do not change device settings or engage in illegal operations without authorization.
During the testing process, it is not allowed to open the cabinet door or touch the battery being tested at will. If operation or inspection is required, the test should be stopped first and safety should be ensured before proceeding.
Regularly maintain and upkeep the container to keep the equipment clean and in good condition. For example, regularly clean the heat dissipation holes of the distribution cabinet to prevent dust accumulation from affecting the heat dissipation effect; Check the elasticity and contact performance of the testing fixture, and replace it promptly if there are any problems.
3、 In terms of data management
Data recording:
During the testing process, the capacity divider will automatically record the charging and discharging data of the battery, such as voltage, current, capacity, time, etc. Operators should regularly check the completeness and accuracy of data records, and promptly handle any abnormalities.
The test data can be exported to a computer or storage device for further analysis and processing. When exporting data, ensure the security and integrity of the data, and do not lose or damage the data.
Data analysis:
Analyze the test data to evaluate the performance and quality of the battery. Professional data analysis software can be used to perform statistical analysis, curve drawing, and other operations on the data, in order to better understand the charging and discharging characteristics and performance trends of the battery.
Classify and screen batteries based on data analysis results. For example, grouping batteries with similar performance for subsequent assembly and use; Separate batteries with abnormal performance for further testing and analysis.
Data backup:
Regularly backup test data to prevent data loss. Data can be backed up to external storage devices such as hard drives, USB drives, etc., or uploaded to cloud servers for storage.
When backing up data, ensure the integrity and accuracy of the backup. Data verification and validation can be performed to ensure that the backed up data is consistent with the original data.
In short, when using a battery capacity divider, it is necessary to strictly follow safety operating procedures, pay attention to equipment maintenance and upkeep, and ensure the accuracy and reliability of test data. Only in this way can the role of the capacity distribution cabinet be fully utilized, providing strong support for battery production, quality control, and performance evaluation.
