Week-3 Challenge: ADVISOR Tool
1. For EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, can the vehicle travel for 45 km with FTP drive cycle? Conclude your observations.
Sol:
2. In the above case, try changing the battery capacity and repeat the simulation.
Sol:
3. Perform gradeability test with PRIUS_Jpn_defaults_in file. Compare your results in table and conclude.
Sol:
In the ADVISOR Vehicle Input GUI select Load File as EV_defaults in file from the drop down menu. Also change the Cargo mass to 500 kg in the bottom right comer of the interface.
Then select 'continue. Here from the drop down menu of the Drive Cycle select 'CYC FTP driving cycle.
Then keep all the parameters as default and select RUN
In the above results we can see that, Distance (km) is 17.8 km. So, the vehicle can't travel a distance of 45 km in a single recharge. Also, it can be seen that, SOC (second plot) has fallen to zero after nearly 2500 seconds.
2. In the above case, try changing the battery capacity and repeat the simulation.
Sol: Changing the Energy Storage to 'ESS_PB65_FocusEV and keeping the other parameters similar to the last case.
Then keep the driving cycle same we RUN the simulation
From the results we can see that. Distance (km) is 17.8 km and the figure hasn't changed but, SOC % at end of 2500 seconds is 0.83 approximately and not zero like the last case. So this means that, in one FTP cycle it covered 17.8 km and charge is still remaining in the battery. So to get how much distance the vehicle will travel in a single charge we need to increase the number of drive cycles for which the simulation is performed. We will perform the simulation for 7 drive cycles.
Change the value of #of cycles value to 7 from 1. Then RUN the simulation.
From the above results we can see that, Distance (km) is 96 km and also the % of SOC as indicated by second plot is 0% by 13000 seconds approximately. So in a single charge the vehicle with this configurations can travel a distance of 96 km in a single charge.
3. Perform gradeability test with PRIUS_Jpn_defaults_in file. Compare your results in table and conclude.
Sol: In the Load File drop down menu select 'PRIUS_Jpn_defaults_in' and rest of the parameters are kept default.
Then select continue
Select gradeability
The speed is at 55M/hr
The gradeability is 1.7%. Then speed is changed to 45 MPH.
The gradeability at 45 Mph has increased to 2.2%. Now speed is 35mph
The gradeability at 45 Mph has increased to 2.4%
So we can conclude by saying that, as speed increases the gradeability decreases.
