| Main functions of the software | 1. The end conditions of each process of limiting time, limiting voltage and limiting current are controlled accurately. 1) Constant current charging end condition (CCC): the end conditions are voltage, time and capacity. 2) Constant voltage charging end condition (CVC): the end conditions are current, time and capacity. 3) Discharge end condition: constant current discharge (DC) end condition is voltage, time or capacity. 2. The charge capacity and energy parameters were calculated. 3. Charge and discharge process editing and management function. 1) Up to 64 step parameters can be set. 2) Up to 256 cycles can be set. 3) Each step can be selected by constant current charging, constant current and constant voltage charging, shelving, constant current discharging, cycling and other attributes. 4) The edited process files can be saved for future use. 4. the charging current can be set from (20-20000) MA, the charging voltage can be set from (0-5000) MV, the discharge voltage can be set from (2000-5000) MV, and the time of each step can be set from 0-9999 min / step. 5. curve display: it can draw the dynamic curve of each battery formation process in real time, including voltage time curve, current time curve, capacity time curve, energy time curve and capacity voltage curve. It can save all the working step curves of each battery (including voltage time, current time, capacity time, electricity time, etc.). The storage conditions of the curve points include voltage difference (≥ 5mv), current difference (≥ 5mA), time difference (≥ 1min), etc. the user can freely choose the sampling conditions of the curve; the curve can be locally enlarged and reduced, the coordinates can be adjusted, and the curve can be displayed and printed Specific data, that is, the time, voltage, current, capacity and electricity of each curve point. 6. chemical data storage: the software can save the corresponding data for more than 30 days, the software scanning frequency is less than 30s, the scanning value is taken every 2 minutes to save, and the value time can be set by itself. According to the voltage and current display curve, the software can view the detailed data of the battery, and the battery displays different colors in different states. 7. Software security control: 1) The data and curve of each point can be saved automatically after the set work step is completed, and the data and curve of each point can be exported in word and excel formats (see the attachment for the export format). The data shall not be lost within 4 hours after offline, and the software has over capacity alarm function; 2) Data saving format: it should be saved in its own format and mdb format, and a cell code field should be added after the cell number; 3) Overcharge protection in constant voltage stage: when the voltage exceeds the set value of overcharge protection, the flow of the channel is stopped, and the set value can be set; 4) Capacity out of tolerance protection: when the capacity of the cell exceeds a certain range, the flow of the channel will be stopped. The current setting conditions are: the capacity of the set flow * 1.35 times; 5) Battery reverse connection protection: set the initial voltage and its proportion of the cell.
