3.1 up to 32 working step parameters can be set;

3.2 up to 256 cycles can be set;

3.3 each working step can be selected from constant current charging, constant current and voltage charging, shelving, constant current discharge, cycle and other attributes;

3.4 the edited process file can be archived for standby.

4. The charging current can be set by (0-5000) MA, the charging voltage can be set by (0-5000) MV, the discharge voltage can be set by (2000-5000) MV, and the time of each step can be set by 1min-1000min.

5. Software security control:

5.2 overcharge protection: when the voltage exceeds the set value of overcharge protection, stop the process of the channel, and the set value can be set;

5.3 capacity out of tolerance protection: when the capacity of the electric core exceeds a certain range, stop the flow of the channel;

6. The battery can be sorted and equipped with indicator light. The sorting mode can be set as capacity, time, open circuit voltage, average voltage, fixed-point voltage, etc.

7. The charge and discharge data of each battery can form a data list form for users to view or print out.

System protection function

1. Over current, under current, over voltage, under voltage and over capacity protection: the upper and lower limit values of battery voltage, current and capacity can be preset in the process. When the limit conditions are reached, the system will automatically force the battery to sleep and prompt the fault in the software interface.

2. Leakage current protection: it is found that there is more than 200mA leakage current for three times in the working state, and the input power of the switching power supply is turned off.

3. Charging overvoltage protection: when the system inspects the battery during charging, when the battery voltage is higher than the upper limit voltage, the battery stops charging.

4. Discharge undervoltage protection: when the system inspects the battery during battery discharge, when the battery voltage is lower than the lower limit voltage, the battery stops discharging.

5. Equipment power-off protection: in case of abnormal power failure of equipment, the current process step can be continued;

6. It has deposit function for abnormal channel;
