Battery Charging and Discharging

This example shows how to use a constant current and constant voltage algorithm to charge and discharge a battery. The Battery CC-CV block is charging and discharging the battery for 10 hours. The initial state-of-charge 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 towards 0. When the battery is discharging, a constant current is used.
