System protection

Global protection parameters (including battery reverse connection protection, voltage lower limit protection, voltage upper limit protection, current upper limit protection, over temperature protection), CC charging protection parameters (abnormal voltage trend protection, abnormal charging current fluctuation protection, abnormal voltage fluctuation protection, charging voltage time setting, abnormal charging voltage rise speed protection), CV Charging protection parameters (including current trend abnormality protection, charging current fluctuation abnormality protection, voltage fluctuation abnormality protection), CC discharge protection parameters (including voltage trend abnormality protection, discharge current fluctuation abnormality protection, voltage fluctuation abnormality protection, discharge voltage dropping speed abnormality protection), idle There are five protection parameters (including voltage abnormal run out protection). When each protection reaches the parameters set by the user, the equipment will automatically stop the channel operation, send an alarm, and record the event for tracking.

Data monitoring and viewing

During the operation of the system, the main window of the software will display the current current, voltage, charge and discharge capacity of each channel in real time, the operation process and the name of the current operation process. The software can also view the current running data or history data at any time through the window, and can be exported manually or automatically in Excel format
