- 4. “Electric cars”generally refers to road going automobiles powered by electricity. Propelled by one electric motor or more using batteries Electric motors give instant torque, and smooth acceleration 4
- 5. Electric carsenjoyed popularity between the late 19th century and early 20th century Early History In 1890s, electric automobiles held many speed and distance records. Before the 1920s, electric automobiles were competing with petroleum-fuelled cars for urban use of a quality service car. 5
- 6.
- 7. From 1990sto Present Renewed interest in the perceived independence that electric cars had from the fluctuations of the hydrocarbon energy market. As on July 2012, other electric automobiles, city cars, and light trucks available in some markets for purchase include the REVAi, Tesla, Volt, etc. 7
- 8. Contributes tocleaner air. To preserve the fossil fuels. Less maintenance More efficient Cost Effective 8
- 9. • Consists ofthree parts 1. Battery 2. Controller 3. AC/DC motor • Controller connected with the accelerator. • 300v DC battery. • AC or DC motor. 240V AC motor or 96- 192 DC motor. 9
- 10. The driverpresses the accelerator which in turn sends the signals to the controller. When fully accelerated, maximum voltage is supplied to the motor. On releasing the accelerator, no voltage is supplied. Two potentiometers are connected. When both potentiometers show same deviation, voltage is supplied further and car moves 10

- 13. • Both theelectric motor and the internal combustion engine needed to run the car. • Combustion engine is used only to charge the battery • Rechargable batteries-Recharged by internal combustion and regenerative braking. • It has a larger battery pack that is plugged into the electric grid for charging, increasing the share of electric power used by the car. 13
- 14.
- 15. • Uses asmall electric battery to support the internal combustion engine. • Provides increased fuel efficiency. • The battery is recharged by both the gasoline engine and regenerative braking. • Regenerative braking captures kinetic energy to charge batteries when the driver pushes the brakes 15
- 16.
- 17. • Battery electricvehicles are all electric. • No internal combustion engine • Needs large recharge time (7-8 hours) • Car halts when the battery dies. • In order to run 80 plus miles, it requires a large battery i.e, 18kWH to 36 kWH. 17
- 18.
- 19. • Companies likeMahindra, Chevrolet and Toyota have launched electric cars in India. • Mahindra launched the first model of EV Reva back in the late 1990s. • However efforts have been made to improve the power and luxury of the car. • In November 2011, Reva NXR was launched which could run 160 km when fully charged. 19
- 20.
- 21. Other carsinclude 1. Hyundai i10 Electric • Termed as zero-emission urban commuter • Consists of a 16kWh battery and a 49kWh electrical motor . • Can be driven upto 160km when fully charged. 21
- 22. 2. Chevrolet E-Spark • The Electric Spark will run on an all-electric drive train. • Will save an estimated 1,892 liters of petrol every year if driven for 64kms every day. 22
- 23. 3. Chevrolet Volt • It is an extended range/plug-in electric car. • When charged completely, it is ready to run on electric charge for up to a range of 40 miles i.e. 64.374 km. • Can go 100 miles in a single tank of fuel. 4. Toyota Prius • The second hybrid car launched at Auto Expo that will be available in Indian market. • The engine includes electric pump. • Requires no accessory belts improving fuel economy. 23
- 24. Different typeof electric cars have different life spans. Battery EVs can run for 5 years or 1,00,000 miles before fully disintegrated. The Plug-in hybrids and hybrids have a longer life span due to continuous recharging from the internal combustion engines and batteries. 24
- 25. ELECTRIC CARS COMBUSTION CARS From electricity produced bybatteries By combustion of fossil fuels and petroleum Slightly higher due to expensive batteries Cheaper than that of electric vehicles due to cheaper parts Doesn’t produce harmful emissions and contributes in clean air. Produces harmful carbon emissions therefore polluting the air. Running cost is low due to lesser number of parts. High due to more number of parts and replacement of oils, etc. ENERGY PRICE POLLUTION RUNNING COST 25
- 26. ELECTRIC CARS COMBUSTION ENGINECARS Expensive due to expensive batteries Cheaper than electric cars. Electricity rate may vary from place to place. Fuel prices remains almost constant in every region across the world. Most companies don’t have certified mechanics for servicing of electric cars. A lot of mechanics know how to service a combustion cars PRICE FUEL RATE SERVICING 26
- 27. ELECTRIC CARS COMBUSTION ENGINECARS Zero greenhouse gases from the cars. Releases harmful greenhouse gases. Less carbon emissions than combustion engine cars 27% more carbon emissions than that of electric cars. But overall, particulate matter produced is 3.6 times more than gasoline cars(in countries relying on natural resources for electricity). Particulate matter production is less. 27
- 28. • Cheaper torun because of low rates of electricity than petrol. • Zero harmful emissions, better for environment. • Nearly 100% recyclable batteries. • Reduces noise pollution. • Can be recharged almost anywhere in urban areas. 28
- 29. • Time requiredto recharge the batteries is more. • Lesser charging stations. • More expensive than the combustion engine cars. • The batteries provided are quite heavy increasing the net weight of the car. 29
- 30. • Electric carscontribute to cleaner air. • Reduced carbon emissions hence less air pollution. • Produce 27% less carbon(monoxide and dioxide) than combustion engines. 30
- 31. • Been inmarket since 1990s and created a new era in field of automobiles. • EV has reduced carbon emissions significantly in the area where it is used. • It restores the balance of ecosystem to some extent. • The future of EVs is bright as there is sufficient Lithium reserves to power 4 billion electric cars. 31
