Electronic Load Fundamentals
Constant current operation mode Constant current (CC) is the most frequent mode in which an electronic load is used. In constant current mode, the load will sink the programmed current independently from the output voltage which is typically forced by the voltage source connected to it (for example a battery). How and where to use CC mode
Battery CC-CV
The Battery CC-CV block is charging and discharging the battery for 10 hours. The initial state of charge (SOC) is equal to 0.3. When the battery is charging, the current is constant until the battery reaches the maximum voltage and the current decreases to 0. When the battery is discharging, the model uses a constant current.
