- 3. INTRODUCTION • An electricvehicle (EV) is one that operates on an electric motor, instead of an engine that generates power by burning a mix of fuel and gases.
- 4. Working of ElectricVehicles The electric vehicle power source is a battery which supplies the electric motor with energy necessary to move the vehicle. The controller acts as a regulator and controls the amount of power received from the batteries so the motor does not burn out. Since the electric vehicles use an electric motor the driver can take advantage of motor’s momentum when pressure is applied on the brakes. Instead of converting all the potential energy in the motor into heat like a fossil fuel powered car does, an electric car uses the forward momentum of the motor to recharge the battery. This process is known as regenerative braking.
- 5. TYPES OF EVs Hybrid Electric Vehicles •HEVs are powered by both petrol and electricity. HEVs start off using the electric motor, then the petrol engine cuts in as load or speed rises. The two motors are controlled by an internal computer which ensures the best economy for driving conditions. HEVs can recharge the battery through regenerative braking . Example: Honda Civic Hybrid, Audi Q7. Battery Electric Vehicles • They are only powered by electricity and do not have a petrol engine, fuel tank or exhaust pipe. They are also known as plug in EVs. Example: BMW i3.
- 6. Comparison Parameters Electric VehiclesOther Vehicles Energy From electricity produced by batteries By combustion of Fuel. Price Higher due to usage of expensive batteries and higher maintenance Cheaper due to more availability and feasibility of resources Pollution Does not produce harmful emissions and contributes in clean air Produces harmful carbon emissions Running Cost Running cost per km is Rs 1.5 Diesel per Km running cost is 4 to 4.5 and petrol per km running cost is 6.5 where as for CNG it is 3 to 3.5
- 7. Lithium Ion Batteries Alithium ion battery is a type of rechargeable battery that is charged and discharged by lithium ions moving between negative and positive electrodes • Efficiency The batteries can work upto 10+ years and over 7000+ charging cycles.
- 8. USAGE OF EVsBY VARIOUS COUNTRIES • As of Dec 2016, China has the worlds largest stock of highways legal light duty plug in electric vehicles with sales of more than 6,00,000+ electric cars. • US ranks second with more than 5,00,000+ electric vehicles. • Japan is the worlds third Largest electric car country market with about 1,00,000+. 0 100000 200000 300000 400000 500000 600000 700000 No. of EVs No. of EVs
- 9. USAGE OF EVsBY INDIA • Gujarat topped the list with sales of just over 4330 units. • WB appeared in the second place with sales of 2,846 units. • followed by UP which sold a total of 2,467 electric vehicles during the said period. • Rajasthan reported sales of around 2,388 EV units. 0 500 1,000 1,500 2,000 2,500 3,000 3,500 4,000 4,500 5,000 NUMBER NUMBER
- 10. TESLA : AREVOLUTION IN EV • Tesla was founded by Elon Musk in 2003. • In June 2008 it announced Model S • Tesla launched Model 3 in 2017 which has a high range battery which can run for 354 kms or 500kms . • Tesla has proved the capability of an electric vehicle by developing high performance sports car and affordable cars for daily use.
- 11. CONCLUSION • There arevarious challenges including financial, technical, supply chain challenges for development of EVs in India. • Charging stations can be increased once the sales of EVs increase, This could be achieved by customer awareness about EVs. • Educational activities can be organized by company so that the awareness about EVs is increased, which would further lead to increase in sales of ev’s.
