It is the best assistant for battery maintenance.

Battery charge discharge tester=constant current discharge of battery pack + online cell voltage inspection + intelligent charging of battery pack + battery pack activation

1. On-line monitoring function: real-time online monitoring of the battery pack and each single cell. The monitoring content includes: the entire battery pack voltage, the voltage of each single cell, the battery pack discharge current, the battery pack monitoring time, and the battery Group discharge capacity and other indicators.

2. The device supports constant current and constant power discharge test modes: it can meet a variety of test requirements. When the battery capacity needs to be tested, the constant current discharge mode can be selected to accurately test the actual capacity of the battery pack; when the battery load capacity needs to be tested , You can select the constant power test mode to accurately simulate the backup power supply time of the battery pack with real load.

3. On-line compensation discharge function: during online discharge, the host display current = battery pack discharge current = host internal dummy load current + actual load current, because the actual load current will change with the online voltage during online discharge, the host internal The dummy load battery will also be adjusted automatically to ensure that the battery pack is always discharged in a true constant current mode

4. Cell monitoring module: The user can choose to set the cell voltage type. Single voltage monitoring module, wired and wireless optional. Each wireless monitoring module can monitor 24 1.2V/2V/4V/6/8V/12V battery cells at the same time, (the whole group of 48V single 2V only needs one module) The wireless module wiring operation is more simple and perfect.

5. When doing the capacity discharge test, four discharge termination conditions can be set at the same time: ①The entire set of voltage termination conditions; ②Single voltage termination conditions; ③Discharge time termination conditions; ④Discharge capacity termination conditions. The ongoing testing process can also be manually terminated as needed;

6.7-inch large touch screen: A large touch screen is used, which can be clicked directly on the screen, which is simple and clear.

7. During the test, the voltage of each cell is detected and displayed in real time: the change track of the voltage of each cell is displayed on the screen of the host, and the cell with the highest and lowest voltage can be automatically displayed in real time, helping you to quickly analyze the single The trend of changes in the body. , And can display the cell voltage histogram.

8. Intelligent judgment program: Let the meter automatically judge whether the single monitor is off or the threshold is really reached, avoiding artificial interruption of the discharge process and making the test process smoother.

9. Histogram and curve analysis and curve comparison function: the instrument can directly perform histogram and curve analysis and curve comparison function for the main test, and the voltage curve can be continuously zoomed in and out 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;

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. Integrated design: The main body of the tester adopts the integrated design of the monitoring part and the power part, and the power part adopts new high-efficiency devices. The use of new special low-heat and high-efficiency load materials and advanced control technology ensure high constant current accuracy.

13. Parallel function: 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.

14. 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. Complete data analysis software: It can display cell voltage, total voltage curve, current curve, capacity histogram, characteristic comparison chart, data table, etc. at the same time, and can automatically generate EXCEL format reports, which is convenient for sending or uploading test data

15. With automatic test protection function: when the entire 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 equipment; it can also be terminated manually as needed The ongoing testing process.

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

17. Storage mode: internal storage and external storage are optional. The minimum interval of internal storage is 1 minute. The minimum external storage is 5 seconds.

1. Carry out automatic charging in strict accordance with the battery charging characteristic curve. The designed charging mode is "constant current → (equal charge and regulated value) constant voltage and current reduction → (automatically judged to) trickle float charge", which has fast charging speed, The advantages of high charging reduction efficiency, no need for manual duty, super long time charging without danger of overcharging, and ensuring the service life of the battery;

2. After the user sets the parameters such as equalizing voltage, floating voltage, charging current, charging time, charging capacity, etc., the tester will automatically execute the charging process and display the charging current, charging capacity, the entire group voltage, and charging time in real time. And other information; the charging parameters can be re-modified during the charging process;

3 When the charging time reaches the set time, the charged capacity reaches the set capacity, the charging module is abnormal or the operation is terminated manually, the charging can be stopped
