Week-3 Challenge: ADVISOR Tool

Aim:-

By using Advisor tool ,

1. we need to find the capacity of EV Vehicle for the cargo mass of 500 kg and result to be observed.

2. Battery Capacity for the above simulation is changed and the result to be observed.

3.To perform Gradeability test with PIRUS and result to be compared.

Description:-

ADVISOR:-

ADVISOR tool is ADvance VehIcle SimulatOR which is a model,script text file and data file used in Matlab which is used for Rapid analysis of performance and fuel economy of conventional , EV and Hybrid vehicles.

This toolbox also provide a detailed simulation and analysis of the drivetrain component, It also provides full advantage of modelling flexibility and analysis in Matlab.

STUDY 1:

EV_default_in Load Capacity Analysis:-

In the Advisor Tool, the vehiche file we choose is EV_default_in and the drivetrain is pure EV. The Cargo Mass Value is increased to 500 kg and all other parameters are kept as default.

The Block Diagram is seen as shown below for the provided vehicle input

Block Diagram:-

By continuing , we land on simulation parameters where the drive cycle we use is FTP drive cycle and we kept the no of cycle as 1 to check whether the vechicle can reach a distance of 45 km but we attain the distance of only 17.77 km. So the drive cycle number is increased to 4.

Result:-

The Vehicle model is run and the vehicle is able to cover a distance of only 41.5 km for 4 drive cycles which is less than the desired distance and the result is seen as shown below

The Vehicle cannot complete the desired distance for the given drive cycle since the battery has been completely discharged.

STUDY 2:-

EV_default_in Analysis by changing the battery capacity:-

The above simulation for Electric Vehicle is repeated by changing the capacity of the battery

The Vehicle Input parameters , the battery module is at 24 which is increased to 28 and other parameters are kept as in above simulation and the input is seen as below

Result:-

The battery capacity is increased to 28 module and then the distance covered by the vehicle for 4 drive cycle is 46.3 km

At higher battery capacity the EV vehicle can cover a longer distance with the given cargo load of 500 kg.

STUDY 3:-

Gradeability of Toyota Prius:-

To test gradeability of PRIUS_JPS_defaults_in model file

Model:-

In vehicle Input PRIUS_JPS_default_in is selected and gradeability test is selected to perform the required test

Block Diagram:-

The grading options are edited by changing the speed and duration of the test as shown below

Test Condition

By keeping the Speed at 15 mph and increasing it by 10 mph for every test for a period of 10 seconds.

Results:-

Gradeability at 15 mph:

The Gradeability is 24.4% at 15 mph (24.1 kmph)

Gradeability at 25 mph:

The Gradeability is 16.5% at 25 mph (40.2 kmph)

Gradeability at 35 mph:

The Gradeability is 13% at 35 mph (56.3 kmph).

The speed of vehicle is increased for a constant time period which leads to decrease in gradeability of the vehicle.

Conclusion:

1.For the given cargo load the capacity of Electric vehicle to travel a distance of 45 km is analysed.

2.By changing the capacity of battery for the Electric vehicle with the same condition as in the study 1 is analysed.

3. The gradeability of Toyato Prius with different speed for constant time is compared.
