Battery Charging and Discharging
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.
How Do Battery Charging Cycles Work?
A charging cycle is completed when a battery goes from completely charged to completely discharged. Therefore, discharging a battery to 50% and then charging it back up to 100% would only be counted as 1/2 of a single battery cycle. Battery cycles are used as an estimate of what a battery''s overall lifespan will be.
