4. Hardware Functions

S. No. Function Function Introduction










Constant-current charging (CC)

The channel is output by constant current with soft start, and no current impact occurs.

Constant-voltage charging (CV)

The channel is output by constant voltage without limiting the output current (the output current is restrained by the maximum current value of the device’s model). CC CV charging

Restrain the output of voltage and current at the same time, and current

hardware with soft start. No impact voltage and current during CC-CV transition.











Constant-current discharging (CD)
The channel is output by constant current with soft start, and no current impact occurs.

Constant-power discharging (CP)

The channel is in constant power discharge mode, and the channel adjusts the current in real time according to the voltage of the battery port.

Constant-voltage discharging

The channel keeps the port battery voltage constant for discharge, and the current decreases gradually until the cut-off voltage is reached.

3 Standing (Rest) Current circuit is cut off, without impact on data acquisition.
4 Stop Channel stopped completely

The circuit of the battery and the machine are completely cut off.
