GDBD-C-300V/300A Battery Discharge Load Bank
? Online monitoring function: When the battery pack is in the state of online discharge, equalization charge, and floating charge, the battery pack and each single cell can be monitored online in real time. The monitoring content includes: the voltage of the entire battery pack, the voltage of each single cell, the battery pack charge and discharge current, the battery pack monitoring time, the battery pack charge and discharge capacity and other indicators.?
?The device can communicate with the PC through the 485 port to control the device discharge.
? Single-cell monitoring module: Users can choose to set the single-cell voltage type. Single-cell voltage monitoring module, wired or wireless optional. Each wireless monitoring module can monitor 24pcs 1.2V\2V\4V\6\8V\12V battery cells at the same time, and the wireless module wiring operation is simpler and more perfect.
? When doing capacity discharge test, four discharge termination conditions can be set at the same time: ① whole group voltage termination condition; ② single cell voltage termination condition; ③ discharge time termination condition; ④ discharge capacity termination condition. The ongoing test process can also be terminated manually as needed;
??During the testing process, the voltage of each individual cell is detected and displayed in real time: the change trajectory of the voltage bar chart of each individual cell is presented on the host screen, and the highest and lowest voltage cells can be automatically displayed in real time to help you quickly analyze the trend of individual cell changes, and it can display a bar chart of individual voltage.
??Intelligent judgment program: The instrument can automatically judge whether the cell monitoring is the clip falling off or the threshold is really reached, avoiding the artificial interruption of the discharge process, making the test process smoother.
??The single cell voltage shutdown threshold can be set for multiple cells: In this way, multiple lagging single cells can be found in a continuous and uninterrupted discharge test.
??Automatic discharge current calculation function: Built in hourly rate discharge coefficient, can automatically calculate the required discharge current based on the nominal capacity and required discharge rate of the tested battery.
? Bar chart and curve analysis and curve comparison function: The instrument can directly perform bar chart and curve analysis and curve comparison on the main tests. The voltage curve can be continuously zoom in and zoom out for easy observation. Clear analysis of data without the need to upload to a PC.
??Discharge parameter template function: Simply call the preset parameters to perform discharge testing. The intelligent judgment program can intelligently determine whether a single unit has fallen off, and if the unit falls off, the test will not be interrupted. Input overvoltage protection, LCD prompt, buzzer alarm; Overcurrent protection, Battery voltage polarity reversal protection;
??Complete communication function: with RS232 communication interface and SD card interface. Data is transmitted to the computer for storage management, allowing for long-term preservation and analysis of historical data; Using SD card to transfer data, testing and saving at any time, lightweight and portable, safe and reliable.
??Powerful PC software analysis function: provides data management, printing, analysis, report statistics, automatic generation of test reports. The voltage curve can be continuously enlarged and reduced for easy observation. Quickly find historical records.
??Complete data analysis software: can simultaneously display single voltage, single internal resistance bar graph, total voltage curve, current curve, capacity bar graph, characteristic comparison chart, data table, etc., can automatically generate EXCEL format report, convenient for test data sending or uploading
??Maintenance suggestion: After the test is completed, all calculation results are automatically displayed, and maintenance suggestions are provided according to the specific test data.
??Storage method: internal storage and external storage are optional. The minimum interval of internal storage is 1 minute. The minimum external storage is 5 seconds.
