M*n features and functions:
● Display mode: Large LCD screen display, Chinese menu prompts, real-time display of all test data: entire battery voltage, single battery voltage, current, capacity, duration and internal temperature, etc.
●Control method: Microcontroller control, set the equalizing voltage, float voltage, discharge termination voltage, charge/discharge current, duration, capacity and other parameters through the keyboard.
● Real-time online patrol detection of parameters of each single battery, and automatic testing and monitoring of various parameters of the battery pack.
● It can quickly and accurately identify f*led batteries and outdated batteries in the battery pack through rapid discharge in a short period of time, estimate the rem*ning capacity of the battery and evaluate the quality of the battery.
Operating mode:
(1) The constant current discharge mode automatically completes the battery capacity test or load capacity test, and can estimate the rem*ning battery capacity through five minutes of rapid discharge and perform capacity analysis.
(2) Intelligent three-stage charging mode: In the early stage of charging, constant current technology is used to keep the charging current constant, which quickly increases the battery voltage. When the charging voltage reaches the upper limit voltage, it automatically switches to constant voltage and reduced current charging, which effectively improves the capacity conversion efficiency of the battery. At the end of charging, it switches to trickle and float charging, so that each battery cell receives balanced power, ensuring that the battery capacity is restored to the maximum extent, effectively solving the problem of cell voltage imbalance and avoiding the danger of battery overvoltage charging.
(3) Cyclic discharge and charge function: Set the discharge/charge hour rate and the high and low limits of the voltage, and automatically cycle the discharge and charge process.
(4) Battery activation function: Set the number of charge and discharge cycles and use pulse charging to activate and rep*r the battery.
Automatic shutdown function: Automatically stop working when any of the following conditions are met: time is up, capacity is up, single protection voltage is up, the entire group protection voltage is up, the number of cycles is up, etc.
● Automatic alarm function: It has an intelligent anti-reverse connection function and automatically alarms when high temperature occurs or the battery pack is disconnected, under-voltage, over-voltage, over-current, etc.
● Real-time monitoring function: Real-time display and control of each set parameter (such as the entire battery voltage, single battery voltage, current, capacity, duration and internal temperature, etc.).
Record query function: The charge/discharge detector can store 16 sets of charge and discharge data, and users can query as needed.
Data transfer function: with standard USB interface and RS232 interface. After charging, the data can be directly uploaded to the computer through USB transfer or RS232 interface, which solves the problem of large-capacity data storage.
Data processing function: After the charge and discharge data are analyzed and processed by the supporting data processing software, various curve charts can be automatically generated and printed.
Computer remote control function: You can set and modify charging and discharging parameters through the computer; control the charging/discharging detector to start and stop charging and discharging.

Supporting data processing software:
directly obt*n the charge and discharge information of the charge/discharge detector. After processing and analysis, it can generate current curves, voltage curves, cell curves, capacity analysis charts, cell bar charts, and characteristic comparison charts. Test data, etc., can be output to Html, Excel and Word to form a test report, and support printing to facilitate user archiving. Based on these charts, the performance change trend of the battery pack can be viewed, providing a scientific basis for judging the quality of the entire pack or single battery.
