Project 1

SOLUTION

As shown in the above flowchart , there are two power sources mention as Fuel Cell (FC) and Battery. The logic which is been told to develop in this is that if the Power demand from the vehicle is less than the minimum FC power than the FC must go on standby and the power should be supplied from the battery storage system and if the power demand is greater than the min FC power than the FC should be used and if the power demand of vehicle is fore than the max power of FC than the Battery should supply the power. The Simulink model is been developed for this as shown below, For this the min FC power is kept between 0 to 1000w Operating region of FC is 1000w to 9000w And max power demand is set till 9000w to 10000w.

The signal Builder block is used as the input to give the power demand required by the vehicle , the simulation is been run for 598 sec and the output such as FC Power, Battery Power and FC status are been studied by connecting it to the scope. If we look inside the logic block of the Simulink the model is as shown below:-

As in signal builder, the power demand is between 0-1000w for 0 to 207 sec, 1000-9000w for 207-393 sec, and above 9000w for the rest of the time, so first the battery should provide power while the FC is on standby, and when the power demand is greater than min FC power, the FC should be used, and if the power demand exceeds max FC power, the battery should be switched back. The following are the scopes of the results, which show FC power, battery power, fuel cell condition, and actual power demand:-
