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
3
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
Why Consider Electric Drive?
4
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
5
Additional Points to Consider Battery life, charge time Electricity production may lead to
emissions EV price vs. conventional vehicle
price
6
Energy independence for the U.S. EVs produce no local emissions
Health Environment
Supports the U.S. economy
Electric Drive Benefits
7
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
Health Benefits
8
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
Environmental Benefits
9
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
Economic Benefits
10
Did You Know?
Many states, particularly California, have public access electric charging stations at libraries, shopping centers, hospitals, and businesses.

11
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
Energy Security Benefits
12
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
Electric Drive – Today and Tomorrow
13
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 topower fuel cell
Do not require large batteries

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 water

15
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
16
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

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?
