Week 9 Challenge

Complete the energy management strategy model with battery, UC and fuel cell for the positive power and distribute the power demand among these components. Set simulation stop time to 598 sec.

The output of the model should be the power request from UC, fuel cell and battery.

Answer:-

Matlab Model:-

Step:1) Selection between Positive Power & Negative Power

Step 2:- If Positive Power

Here as per the power demand range we are choosing between Battry, Fuel Cell and Ultra capacitor.

battery limits:-

FC limits:-

UC limits:-

Step 3) Fuel Cell Backup Calculation

Step4) Battery back up calculation

Step5) Negative Power

Overall Matlab Model:-

Power Demand Input:-

Conclusion:-

Here we have simulated the energy mngement system for an electric vehicle. As per the power demand the vehicle will shift the requirement which will be the most efficient ( battery, FC or UC). In the results shown above we can observe that when the power demand is upto 23000w the vehicle will run on battery, when power demand is in between 23000w to 55000w, it will run on FC and when it is beyond 55000w it will run on ultra capacitor. As the power demand is positive the regeneration is zero.
