Week-3 Challenge: ADVISOR Tool
Use ADVISOR tool and simulate the following
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.
By taking the case of typical EV , we are simulsting it in advisor tool.
Specification are as follows
Battery Electric vehicle Specification
Lead Acid Battery with 25 modules having nominal volatage 308 volts and efficiency is 92 %
Motor - AC induction Motor with 75 kw
Cargo Mass is 500 kg
Now taking input drive cycle is CYC_FTP which is 11 miles long distance, to drain battery completely soc 0%. calculation of range of vehicles 4 drive cycle are considered. So that vehicle can travel upto 25 miles.
from the given results show that
plot first explain drive cycle for which vehicle was travelled.
plot second shows SOC fall with time
plot third and fourth shows power output according to throttle condition.
from the graph it shows that Soc becomes zero after 2.5 drive cycle, hence concluded that vehicle cannot run for 25 miles in single charge.
2. In the above case, try changing the battery capacity and repeat the simulation.
In this case also same default condition are taken for the vehicle simulation and here we are going to increase the battery capacity on order to accelerate the vehicle.
here 3 extra modules of the battery are taken in addition to 25 so that to overcome the 25 miles distance.
so the total modules to 28 and nominal voltage to 345 volts.
Hence it shows that after addition of 3 more modules to the battery SOC is 0% after completion of all full 4 cycles.
3. Perform gradeability test with PRIUS_Jpn_defaults_in file
Compare your results in table and conclude.
Model TOYOTA prius parallel hybrid vehicle.
It uses both battery and IC engine to move the wheels.The differential is connected to the motor and the IC engine which is called power split device. Power split divides the power according to the throttle condition and try to keep the engine efficiency maximum.It also provide additional power via battery during transient condition
vehicle Specification
Power( IC Engine)- 43kw
Battery Capacity (nickel Metal Hydride) of 40 modules having 308 nominal voltage.
Generator diring regenerative mode 15 kw
Transmission CVT
Drive- Front Wheel Drive
For gradeability test, keeping grade value constant we change the speed to obtain maximum gradeability for 10sec.
case 1 speed 5mph
case2 speed 10mph
case 3 speed 30mph
| sl no | speed(mph) | Gradeability(%) |
| 1 | 5 | 18.1 |
| 2 | 10 | 23.7 |
| 3 | 15 | 26.4 |
| 4 | 20 | 25.5 |
| 5 | 25 | 24.1 |
| 6 | 30 | 13.8 |
| 7 | 35 | 13.1 |
| 8 | 40 | 12.6 |
hence gradeability is highest at speed between 10 to 25mph.
