How to detect battery quality

by:dcfpower     2021-03-23

1. Judging from the appearance, observe whether the appearance is deformed, bulging, leaking, cracked, scorched, and there is no oxide seepage at the screw connection, etc.

2. If there is no abnormal appearance in the load measurement, the UPS works in battery mode with a certain amount of load. If the discharge time is significantly shorter than the normal discharge time, it will not return to normal after 8 hours of charging. Standby time to determine battery aging.

Three. Use a battery analyzer to test a simple battery tester, which can only measure the battery voltage in a high-current discharge state, and roughly judge the battery’s capacity. At present, the more advanced battery tester can accurately measure the cold start current (CCA) in addition to the start-up discharge, such as the WDKR-J battery discharge monitor. The judgment method is as follows: 1. Connect the battery tester to the battery for 10-15 seconds when in use, and keep the voltage at 10.5-11.6V, indicating that the capacity is sufficient and the battery has no fault; 2. Keep the voltage at 9.6V-10.5V, indicating that the capacity is insufficient , The battery is not faulty; 3. The voltage drops below 9.6V, indicating that the capacity is severely insufficient or the battery is faulty.

Detailed product features:

1. It has the functions of internal resistance test and capacity evaluation for battery packs.

2. It has the function of online monitoring the performance of multiple indicators of the battery pack: when the battery pack is in the online discharge, equalizing, and floating state, the battery pack and each single cell can be real-time Online monitoring, the monitoring content includes: the entire battery pack voltage, the voltage of each single cell, the battery pack charging and discharging current, the battery pack monitoring time, the battery pack charging and discharging capacity and other indicators.

3. It has the function of quickly and accurately identifying the pros and cons of batteries.

It has the function of checking the discharge test of the battery pack according to a variety of discharge rates to accurately know the true capacity of the battery; the online compensation discharge function realizes dynamic compensation during the entire discharge process to ensure the true battery pack The constant current discharge.

4. During the on-line discharge process of the equipment, monitor the voltage of each single battery in real time;

5. The voltage of the entire group is 24V/48V/110V/220V/380V, The battery packs with cell voltages of 2V, 6V and 12V are tested, and the user can choose to set the cell voltage type. Single voltage monitoring module, wired and wireless optional.

6. Four discharge termination conditions can be set at the same time during the capacity discharge test:

①The entire set of voltage termination conditions;

②The cell voltage termination Conditions;

③Discharge time termination conditions;

④Discharge capacity termination conditions. You can also manually terminate the ongoing test process according to your needs;

7, 7-inch color touch screen.

8. The operation is simple and convenient: all adopt modular interface, good man-machine dialogue function, simple operation, clear flow, each interface and operation step have simple prompts, which fundamentally avoids wrong operation .

9. The instrument can directly perform bar graph and curve analysis and curve comparison functions on the main test results. The voltage curve can be continuously enlarged and reduced for easy observation. Data can be analyzed clearly without uploading to a PC.

10. Discharge parameter template function, directly call preset parameters to discharge test. The intelligent judgment program can intelligently judge whether the monomer falls off, and the test will not be interrupted if the monomer falls off. Input terminal overvoltage protection, LCD prompt, buzzer alarm;

Overcurrent protection, LCD prompt, buzzer alarm; battery voltage polarity reverse protection, LCD prompt, buzzer alarm;< /p>

11. Complete communication function, with RS232 communication interface and SD card interface. The data is transferred to the computer for warehousing management, and long-term historical data storage and analysis can be carried out; the SD card is used to transfer the data, and the test can be saved at any time, which is light and portable, safe and reliable.

12. The mainframe of the tester adopts the integrated design of the monitoring part and the power part, and the power part adopts new high-efficiency devices.

13. The use of new special low-heat and high-efficiency load materials and advanced control technology ensure high constant current accuracy.

14. The instrument has a parallel function and can also be connected to an external load, so that the instrument can test various large-capacity batteries.

15. Powerful PC software analysis functions: provide data management, printing, analysis, report statistics, and automatic generation of test reports and reports. The voltage curve can be continuously enlarged and reduced for easy observation. Quickly find historical records.

16. With automatic test protection function: when the whole group or single battery is detected during the test process, the test will be automatically terminated to prevent over-discharge of the battery and completely avoid impact on the device ; The ongoing testing process can also be manually terminated as needed.

17. After the test is completed, all calculation results are automatically displayed, and maintenance suggestions are provided according to the specific test data.

18. Storage mode: internal storage or external storage can be selected. The minimum interval for internal storage is 1 minute. The minimum external storage is 5 seconds.
