SOLUTION

SIMULINK ULTRACAPACITOR MODEL

As a power demand source, the Signal Builder block is employed. Current and voltage calculation subsystems, as well as SOC calculation subsystems, are included in the Ultracapacitor subsystem. The current, voltage, open circuit voltage, and charge calculation subsystems are generated in the charge and voltage calculation subsystem.Power demand from the signal builder and feedback from the SOC are the present subsystem's inputs. Then, using the formula, the SOC calculation is performed.

SIMULATION RESULTS:-

We can observe from the graph above that a sudden peak load power consumption of more than 100kW is necessary. The ultracapacitor can handle that without any problems. It can also be charged quickly to a certain value with less than 25 kw of power. It can also reach a peak three to four times higher than typical. Conclusion: Based on the graph, we can deduce that if the electric vehicle's usual load is 100 kw, the peak load will be around 600 kw to match the battery need.
