Week 8 Challenge

The top level view of the model is shown below. The power request is taken as the input termed as PUC here.

The subsystem consists of current calculation and SOC estimation sub-models.

UC_Current(I) is calculated using the formula and model is desgined

where,

SOC = State of charge

V_max = Maximum Voltage

R = Resistance

PUC =Power from ultra-capacitor

Output voltage is calculated as per the formula and model is designed

Open circuit voltage is calculated as per the formula and model is designed

Charge_Q is calculated as per the formula and model is designed

where,

C = Capacitance

SOC is calculated as per the formula and model is designed

where,

n = efficiency

Results : The simulation is for 598 seconds

The output voltage obtained
