Week 9 Challenge

Q1) 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.

Energy management:

The energy management system is used to determine which energy source is to be used and which is to be charged

The input to the model is the power requirement of the vehicle which is given from a signal builder and the positive requirement is separated using the switch block and is fed into the subsystem

The subsystem has two parts one for the ultracapacitor and the other for the fuel cell. The power demand is separated according to the ultracapacitor test values as low and high and the result is compared with the soc of the battery which is gives as a ramp signal and the result from both low and high and added to give the entire UC power request.

The fuel cell backup is done by comparing the low and high values of UC and soc of battery and the result is added to give the backup which is then added with result obtained from the fuel cell test containing the power demand.
