1.High-precision calibration: charging current, discharge current, charging voltage and discharge voltage are all calibrated by Agilent with high precision to ensure the accuracy of current and voltage within 0.5%. 2.Independent channels with configurable parameter and condition setting for each individual channel. 3.Equipped with complete input and output devices, hardware and software protection, polarity reverse protection, power failure protection and etc. 4.Precise control without overshoot during CC-CV and CV-CC transition. 5.Strong software system and friendly HMI (Human-Machine-Interface). 6.Multiple conditions (capacity, time, open circuit voltage, discharge platform, etc.) for battery sorting. 7.Automatically calculate the constant current charge ratio, capacity loss, discharge efficiency, average voltage, median voltage and other data. 8.Equipment hardware control loop uses current and voltage double loop control. No ripple for constant current and constant voltage switching. 9.Data exported as EXCEL and TXT files, as well as chart files, can be shown as data analysis waves for charging and discharging, voltage, capacity, current & time feature.
