Week-3 Challenge: ADVISOR Tool

ADVISOR TOOL:

AIM:

1.For EV_defaults_in file,if cargo mass is 500kg with all other default conditions,can the vehicle travel for 45Km with FTP drive cycle?

2.In the above case,Try changing the battery capacity and repeat the simulation.

3.Perform gradeability test with PRIUS_JPN_defaults_in file.

OBJECTIVES:

Using advisor tool added with MATLAB to simulate different EV/HEV and understand the results from the simulation.we include for each vehicle the model image of vehicle inputs,simulation parameters,and results from those simulations.

ADVISOR TOOL is a rapid analysis of the performance and fuel economy of EV/HEV.it is used as backward looking facing model.in this we just look up to tables and not based on any model.in this we just look up to tables and not based on any model file like in matlab model.

PROCEDURE:

1.first of all we open the vehicle input page in ADVISOR tool and the load the EV_defaults_in file and change the cargo mass to 500kg keeping all other default conditions

• on this simulation parameter we just change the drive cycle to CYC_FTP out of a number of different drive cycles.
• as the vehicle in 1 cycle takes 2477 sec to cover distance of 17.77km with 25modules of battery,where the maximum and average speed are 91.25km/hr,25.82km/hr respectively
• according to CYC_FTP PLOT 43% speed of these vehicles remains between 0 to 8km/hr.It also gains the maximum speed in the intial 500 sec

as we can see an error occur as the EV ran out of battery for this type of drive cycle

as we need total distance covered to be 45 kilometers and this drive cycle can only complete 17.8 so we need more than 1 drive cycle to complete more than 45 kilometres. so we can use 3 drive cycles

as we can see a warning sign pops up which means that the distance is more than the range of the current battery pack so the vehicle can not travel 45 kilometers but will be short by 3.2 kilometers.

2)IN THE ABOVE CASE,TRY CHANGING THE BATTERY CAPACITY AND REPEAT THE SIMULATION.

THE current battery capacity is kept at 25 we need to increase the battery pack capacity so that the vehicle can run more than 45kms

so for this we will increase the battery capacity from 25 to 45

by increasing the battery capacity we can see that the range has been increased to 53.3km which is more than the required range we need.

3)PERFORM GRADEABILITY TEST WITH PRIUS_IPN_defaults_in'file from the load file option to load the prius model

hit continue and select the grade options to open the grade test options in this we need to change the option which will include both fuel and energy storage system.hence we will select all systems to enable and in basic parameters the speed of the vehicle can be controlled we need to change the speed from 5-35 mph with an increment of 5mph to check the gradebility at different speeds.

after running the prius model with different speeds we can check the gradebility percentage we need to take the values at different speeds and tabulate the information

from the table .we can see that the gradebility decrease with increase in speed the maximum gradebility during 5mph and lowest during 35mph
