- 1. Future Trends In Electric Vehicles By:- Adarsh Singh Sachin Yadav Ashmit Prasad Gaurav Kumar Nitesh Yadav Guided By:- Dr. Shailendra Kumar
- 2. Future Trends In Electric Car Introduction To Key Technologies Wireless Charging Battery Swap Technology Renewable Energy
- 3. A Little Thought ““Gasoline cars will be a history, As soon as we solve the electric cars mystery”” ~ Anonymous
- 4. • What is Powertrain? • Designing Electric Vehicles bottom up. • More Efficient and Reliable Electric Vehicles. • Powertrain Integrated Design. • Cost, efficiency, safety and reliability will improve. Powertrain Design • Energy density the most vital parameter. • 5 fold increase potentials with concept like Fuel cell and Lithium Air cells(1000 Wh/kg). • Current most used is li-ion cells with 200 Wh/kg energy density. • Specific purpose designs like Li-C cells which have small capacity but charge within 90s. • Supercapacitors for sudden power surge. Battery Technology Solar Power Technology • Powering Electric Vehicles by solar cells. • Limited power per unit area currently restricts fully solar powered EV. • Concepts of solar roofs to increase range relatively more practical as of now. Fuel Cell Technology • Powered by hydrogen cells. • Extremely large range and quick fueling times. • Concept expected in far future due to safety concerns, financial implications and infrastructure development constraints. Introduction To Some Key Futuristic Trends
- 5. • Switching out depleted battery with a recharged one. • Fastest battery charging technique. • Implemented on small scale by Taiwan. • Challenge - Uniform and universal designing. • Standardised battery, battery interface and chassis required. Battery Swap • Commercially available for mobiles. • Works on principle of induction. • On road charging extension about the concept also in talks but limited to theory. • On road concept can be revolutionary as battery size, range, charging time, cost etc will reduce to several folds. • Implemented on small scale in Korea for public transport. Wireless Charging Smart Charging • Involves control of charging power as function of time. • Reducing charging costs. • Can use power when available more(Night times). • Using the car as a storage for the renewables and a grid back up with the use of vehicle-to-grid. • Amsterdam tested Vehicle to grid on small scale. Autonomous Charging • Full capacity semi-autonomous driving already developed by companies like tesla. • plethora of opportunities in the future such as shared and connected mobility. • Cities decongested of cars and parking spaces, higher utilization of vehicles, lower cost of mobility and more efficient point-to-point connectivity. Introduction To Some Key Futuristic Trends
- 6. Wireless Charging Of Electric Vehicle
- 7. Capacitive Wireless Power Transfer Power is transferred between the electrodes such as metal plates via electric field 02 Magnetic Gear Wireless Power Transformer In this method two synchronised permanent magnets, one acts as generator and other acts as receiving mode 03 Inductive Wireless Power Transfer Power is transferred between coils of wire via magnetic field 01 Wireless Charging Of Electric Vehicle
- 8. 2 Expensive Project Advantage And Disadvantage Of Wireless Charging 1 3 Battery size is reduced No wired connection between source and Car Time Efficient 1 2 3 Slow Charging Speed Energy Loss
- 10. Advantage of Battery Swap Technology Electric Easy Economic Ecologic Quick and easy refiling like fuel in cars Take less for the car to be recharged No issue of range as it will have stations Batteries can be charged conviently
- 11. Disadvantage Of Battery Swap Technology Battery Health Checkup Wear and tear of connection between battery and car Standardized battery interface Consumer Acceptance
- 12. Renewable Energy for Electric Vehicle
- 14. CHARGING OF EV FROM WIND ENERGY 1. Long distance between the wind turbine and EV 2. The power scale are different • Wind turbine (~ MW) • EV charger (~KW) 3. Generation is predominantly in winter and in the night
- 15. CHARGING OF EV FROM SOLAR ENERGY 1. Close proximity (Rooftop PV)Long distance (solar farm) 2. The power scale are similar • Rooftop PV (~ KW) • EV charger (~KW) 3. Generation is predominantly in summer and in the day
- 16. Some concepts here are not practical and feasible at all right now, and the list is topped by Fuel Cell Concept. But just 1 years back, did you imagine you could attend your college like this? Did you imagine a whole world over few inch screens just a few years back? Was it practical a decade back to think a normal citizen can access satellite images of any place in the world? We are humans. We are powered by imagination. And we use this power harnessed for change. These two sentences are the reason we have come this far together as mankind and we will move ahead with exponential rates in future too. Electric mobility may change the world for every single organism on Earth. And it is Coming Soon..... and we, the STEM community are the ones Bringing it Soon..... Summary
