E N D
Objectives • Describe how electric drive vehicles may help improve public health • Describe the benefits of electric drive vehicles to the environment • Explain how electric drive vehicles may help stimulate the economy • Describe what energy security is and how using electric drive vehicles can help attain it • Explain the future of electric drive vehicles • Explain the suggested actions to support electric drive vehicles
Why Consider Electric Drive? • No tailpipe emissions – effects of air pollution and global warming are lessened • Electricity used is produced domestically • Renewable sources can be used to generate the electricity needed • Domestically produced electricity increases energy independence
Advantages of Electric Drive • Best of both electric and conventional systems • Range and efficiency can be improved • EVs and conventional vehicles are essentially driven in the same manner • All-electric systems do not produce any emissions (use grid power) • Increased use = decreased reliance on foreign oil • Low maintenance costs
Additional Points to Consider • Battery life, charge time • Electricity production may lead to emissions • EV price vs. conventional vehicle price
Electric Drive Benefits • Energy independence for the U.S. • EVs produce no local emissions • Health • Environment • Supports the U.S. economy
Health Benefits • High air pollution levels negatively affect public health • Vehicles that burn conventional fuels create emissions that add to these levels • EVs produce fewer emissions, some produce no emissions at all • Lower emissions = improved air quality
Environmental Benefits • Fewer CO2 emissions through increased efficiency • Greenhouse gas emissions contribute to global warming – use of EVs would help reduce these emissions • EV emissions vary by type • BEVs produce no local emissions
Economic Benefits • EVs reduce fuel costs for consumers • Advanced vehicle component sector employs 155,000 Americans • Federal, state, local incentives help reduce the initial purchase price of EVs
Many states, particularly California, have public access electric charging stations at libraries, shopping centers, hospitals, and businesses. Source: DOE.
Energy Security Benefits • Increased EV use = lessened reliance on foreign oil • 94% of transportation in the U.S. utilizes oil as its fuel source • Nearly half of U.S. oil consumption comes from foreign sources • Utilization of EVs will reduce this reliance
Electric Drive – Today and Tomorrow • More technologically refined vehicles • Recent BEV developments • Many light-duty HEV options • Some medium- and heavy-duty EVs are also available • Medium- and heavy-duty applications may utilize diesel-electric hybrid systems
The Future of Electric Drive • Fuel Cell Electric Vehicles • Produces electricity while converting hydrogen and oxygen into water • Platinum may be required for some components • Hydrogen gas used to power fuel cell • Do not require large batteries Figure 1: Mercedes-Benz F600 fuel cell prototype.

The Future of Electric Drive • Fuel Cell Electric Vehicles • Fuel cell and fuel storage tank • Onboard reformation • Proton exchange membrane facilitates reaction • Captures energy from chemical reaction • Only byproduct is waterand heat Figure 2: FCEV proton exchange membrane. Source: NAFTC.
Wireless Charging • Can shorten charging times • Electricity is sent through charging pad under vehicle • Automatically charge the batteries when placed within a specified range of charger • Operates at 240 volts, Level 2
Suggested Actions • Federal and state incentives for the implementation of EVs • Information can be obtained from local dealerships • Limited range of current BEVs • Extended range technologies must be developed
Upon completing this presentation, can you: • Describe how electric drive vehicles may help improve public health? • Describe the benefits of electric drive vehicles to the environment? • Explain how electric drive vehicles may help stimulate the economy? • Describe what energy security is and how using electric drive vehicles can help attain it? • Explain the future of electric drive vehicles? • Explain the suggested actions to support electric drive vehicles?
Test Your Knowledge • Give an example of an EV that is successfully reducing carbon emissions. • True or False: An extensive electrical grid acts as the distribution network. • True or False: There are many tax incentives for alternative fuel and advanced technology vehicles.
