Notes
This function sets up the initial conditions for a ground segment involving battery charging or discharging. For charging segments, the charging time is determined by the battery with the lowest state of charge.
Calculation Process For charging:
Find lowest battery state of charge
- Calculate charging time based on:
t = (SOC_target - SOC_current) / C_rate
Add cooling time
Discretize time points
- For discharging:
Use specified discharge time
Discretize time points
- Major Assumptions
Charging time determined by lowest SOC battery
Constant C-rate charging
Linear SOC increase during charging
Uniform cooling time added
