Week-4 Challenge WOT Condition Part-2
Question 1
Answer: Mapped model consists of predifined datas in lookup table.It does not depend on the real time situation and will deliver the same out put regardless of the current situation.But in dynamic mode a feed back is taken from the output so that real time situation is analysed and the input is provided accordingly.
Question 3
Answer:Here the driving cycle is changed to WOT and the nominal reference speed is 60 deceleration time is 30 that is after the speed wiil start to decrease at 30.From the graph we can see that the speed achieved is 90 approximately.From the battery current graph the negative current show the charging of battery during braking.
Question 2:
Answer:
Miles per gallon gasoline equivalent (MPGe or MPGge) is a measure of the average distance traveled per unit of energy consumed. MPGe is used by the United States Environmental Protection Agency (EPA) to compare energy consumption of alternative fuel vehicles, plug-in electric vehicles and other advanced technology vehicles with the energy consumption of conventional internal combustion vehicles rated in miles per U.S gallon
The unit of energy consumed is deemed to be 33.7 kilowatt hours without regard to the efficiency of conversion of heat energy into electrical energy, also measured in kilowatt hours. The equivalence of this unit to energy in a gallon of gasoline is true if and only if the heat engine, generating equipment, and power delivery to the car battery are 100% efficient. Actual heat engines differ vastly from this assumption.Here the calculation is done by converting battery power to kilowatt and is divided by 33.7
Question 4:
Answer:EV is having more fuel efficiency as compared to HEV.
