Week 8 Challenge

Aim: To model the energy storage device as an ultracapacitor and analysis its operating characteristics according to the power demand by running the model for 592 seconds

Procedure:

The signal builder block is used as a power demand source.

In the Ultracapacitor subsystem, current and voltage calculation

The current, open-circuit, and charge calculation subsystems are formed in the charge and voltage calculation subsystem.

Input to the current subsystem is power demand from the signal builder and feedback from the SOC.

OCV=Int(I/C)*dt

Charge calculation:

Q=C*Vmax

Voltage Calculation:

V=(SOC*Vmax)-(I*R)

SOC calculation:

SOC=Int((I*eff)/Q)*dt

The above graph shows that a sudden peak load power demand of above 100kw is required.

Conclusion: From the graph, we came to know that if the electric vehicle's average load is 100kw, then the peak load is about 600kw to meet the battery demand.
