Week-3 Challenge: ADVISOR Tool

AIM :

• For EV defaults in file simulate for the range of vehicle carrying the Payload of 500kg
• Changing the better capacity of the above Vehicle for the next simulation
• To perfom the Gradeability test for PRIUS_Jpn defaults_in Vehicle.

Introduction of ADVISOR:

ADVISOR : ADvanced VehIcle SimulatOR

This too, originally developed by the National Renewable Energy laboratory (NREL), allow users to simulate and analyze conventional, advanced , light and heavy vehicles including hybrid and fuly electric and fuel cell vehicles.

ADVISOR approximate the continious behavior of a vehicle as a series of discreate steps during each of which the components are assumed to be STEADY STATE. This allows us to plot the graphs as per our requriments.

1.EV_defaults_in:

• To check if the vehicle can travel for 45km with the cargo mass of 500 kg with all other defaults conditions with FTP drive cycle.

Motor characteristics:

Vehicle Configuration:

Drive cycle :

• FTP drive cycle consists of a total distance of 7.45 miles (i.e 11.989 km) in a single cycle. in order to check for the range for 45km. the Vehicle must run atleast 3 drive cycles.

Plots after 3 Drive cycles:

• The 1st plot shows the driver cycle speed aganist time.
• The 2nd plot shows that battery SOC has declined to 0 at time ca.5500s even before.
• Emission is absolute zero because it is an elecric vehicle. The 3rd plot shows this
• The 4th plot shows the distance traveeled by the Vehicle by carrying the 500 kg cargo

• THE VEHICLE FAILED TO TRAVEL THE DISTANCE OF 45 KM UNDER FTP CYCLE WITH AN PAYLOAD OF 500KG

2. To change the Battery Capacity for EV_defaults_in in the above simulation and check for the Range

• The number of battery modules is increased from default 25 to 30 check for the range.
• Increase in the Number of battery modules will increse the nominal voltage from 308 volts to 370 volts.
• This also resulted in the increse the overall weight of the vehicle.

Plots:

• The 1st plot shows that drive cycle Sped vs time
• From the 2nd plot the the battery SOC has declined to 5800 or less.
• the total distace travelled is 47.9 km

WITH INCREASE IN THE BATTERY MODULE BY 5 NUMBER THE VEHIICLE MANAGED TO TRAVEL 45 KM WITH A PAYLOD OF 500KG

3.PIRUS_Jpn_defaults_in

To perform the gradeablity test for pirus_jpn_defaults_in vehicle.

Drive cycle:

Gradeablity test can be performed by two methods

• Gradeablity at some defined speed, grade test option available test
• Greadeablity with constatnt grade ubder any of the drive cycle

Case 1

speed at 10 mph for 50 seconds

The Gradeablitiy is 34% with speed of 16.1 kmph for 50 seconds

CASE 2:

speed @ 20mph for 50 seconds

The Gradeablitiy is 23.5% with speed of 32.2 kmph for 50 seconds

CASE :

speed @ 30mph for 50 seconds

The Gradeablitiy is 18% with speed of 48.3 kmph for 50 seconds

CASE 4:

speed @ 40mph for 50 seconds

The Gradeablitiy is 15.8% with speed of 64.4 kmph for 50 seconds

CASE 5:

speed @ 50mph for 50 seconds

The Gradeablitiy is 13.6% with speed of 80.5 kmph for 50 seconds

CASE 6:

If the gradeablity is greater than 14% ie (G>14%) the grade test fails when gradeabiity is more than the max gradeablity at respective speed.

Conclusion :

SPEED(KMPH)	GRADEABLITY IN % (FOR 50 SECONDS)
16.1	34.4%
32.2	23.5
48.3	18.8
64.4	15.8
80.5`	13.6

• THE GRADEABILITY DECREASES WITH INCRESE IN THE SPEED
• AT CERTAIN GRADE THE VEHICLE DECREASES UPTO A POINT AND THAN REACHES THE STEADY STATE AS THE PLOT
