1. Course : Primary Movers For Automobile Topic of Presentation :Limitations of ICE Vehicles- Role of electrics-Components of EVs Guided By : Dr. AmbaPrasada Rao G Submitted By: Abhishek Yamini Roll No: 143701 Date: 13/10/2014 2. Why Hybrid Electric Vehicles are IMPORTANT ? 38% 22% 40% Percentage of Vehicles sold in 1900 classified on the basis of prime mover Electric Gasoline Steam 3. Limitations of Conventional ICE Vehicles 1. Fuel Conversion Efficiency: On an average < < 2. Mismatch of engine fuel efficiency characteristics with real-world driving conditions. 3. Waste of vehicle kinetic energy while braking, especially when driving in urban conditions. 4. Low efficiency of hydraulic transmission(automatic ). 5. Starting and Stopping of vehicle is constraint. 6. Tailpipe Emissions CO2, soot(optional), VOC etc are unavoidable. 7. Engines performance outside its optimum operating range suffers greatly Section 1 4. Well to Wheel Efficiency Data: We will come back to 30.2 % Hybrid 5. 66 87.5 82.2 88.6 82.2 66.5 41.6 30.2 17.8 15.1 43.9 36.6 24.8 15.8 12.4 BEV FCEV HYBRID DIESEL PETROL Efficiency Comparison Well to Tank % Tank to Wheel % Well to Wheel% 6. Rush Hour Limitations What is Rush Hour ? What is the average energy used by each of the technologies ? Justify the difference. Are we talking about well to wheel energy used or tank to wheel energy used ? 7. Roll of Electrics Components of EV 1. Definition 2. Applications of Modules 3. Classification of Electric Vehicles (EV) 4. Important Modules 5. Comparison with conventional vehicles Section 2 Conclusion of Previous Section 8. Define EV/HEV : 1. An electric vehicle (EV), also referred to as an electric drive vehicle, uses one or more electric motors or traction motors for propulsion. An electric vehicle may be powered through a collector system by electricity from off-vehicle sources, or may be self-contained with a battery or generator to convert fuel to electricity. EVs include road and rail vehicles, surface and underwater vessels, electric aircraft and electrically-powered space vehicles. 2. A hybrid electric vehicle (HEV) Combines a conventional internal combustion engine(ICE) propulsion system with an electric propulsion system There are a variety of HEV types, and the degree to which they function as EVs varies as well. The most common form of HEV is the hybrid electric car, although hybrid electric trucks (pickups and tractors) and buses also exist. 9. Video : Hybrid EV explained (Paris Auto show 2014 Kia optima T hybrid ) 10. Schematic diagram of a typical EV 11. Configurations = ( ) ( + ) 12. Classification of Electric vehicle (based on movers of automobile ) EV BEV HEV SHEV PHEV P-in-HEV CHEV SPHEV PEV FCEV SEV SCHEV Green: Can be Partially Zero Emission Vehicle CARB: California Air Research Board 13. Well to Wheel Efficiency Data: Explain how we get tank to wheel efficiency of 30.2 % . 14.
