Week-4 Challenge WOT Condition Part-2

1.Mapped and Dynamic Model of Engine,Motor,Generator :

Mapped Model:

1.In Modelling of Vehicle, Mapped model can be referred as Static Model also. In which the Data should be provided in Look up table.

2. It represents the macro engine characteristics in Lookup table like Brake torque, fuel air,air flow mass flow,temperature,efficiency,emissions functions commanded load and measured.

Dynamic Model:

1. Dynamic model represents the Actual model of the components. It is intake air flow and turbo charger dynamics.

2. We can activate based on application.

3.These models are suitable for the Design Control,estimator,diagnostic algorithms that depends on the subsystem .

Change the Model Type:

Passenger Car > Electrical plant > Motor generation EV mapped > We can see the Default model

Passenger Car > Electrical plant > Motor generation EV mapped > By giving right click we can see the '' Variant"

> open lable mode > select as per our requirement.

Model Calculation for Mile per Gallon:

Calculating the battery power and Vehicle speed in miles per gallon is uesd to find that the Battery is compare to engine fuel consumption. This mile per gallon is equivalent to the energy generated by electric power.

The vehicle speed and battery power are input to compare the fuel economy of engine with battery, we simply convert to the battery piower to gallon and vehicle speed to mile using following model steps

Vehicle speed is main criteria for the evalating fuel consumpion. Distance in Km.Total battery power required to propel the vehicle is simulated along way, battery is converted into 'kw' and battery rating is obtained in terms of 'kWh'. Torque generated by the vehicle while moving is also main factor to be considered.

3.

Run the HEV ReferenceApplication with WOT drive cycle. Change the grade and wind velocity in the environment block. Comment on the results.

Changed to WOT Driving cycle.

Changing Grade value 5

Wind velocity value 6

Velocity reaches approx. 60m/s with Considering Grade and Wind.

Battery state of charge is decreases up to 20 sec and ramains conastant at 70 all these due to sudden fully acceleration condition.

4.

Keeping all other parameters same, compare the simulated results of Hybrid and Pure electric powertrains

HEV

EV

With default conditions of HEV& EV set to Run the simulation and Results are shown above.

Temperature of HEV higher power and more aggressive charge/discharge profile due to Engine and Electrical components.

SOC increases in HEV while running in Engine drive mode.
