EV & Charging Station
Pure operational mission is to pursue low carbon transport option, proving values for the selection of EV, energy efficient, hybrid vehicles as well as public transport.
Electric Vehicles and Future of Transportation
Electric vehicle (EVs) run on electricity only. They are propelled by one or more electric motors powered by rechargeable battery banks.
EVs have several advantages over gasoline vehicles:
• Environmentally friendly. EVs emit no tailpipe pollutants, although the power plant producing the electricity may emit them. Electricity from nuclear-, hydro-, solar-, or wind- powered plants causes no air pollutants.
• Performance benefits. Electric motors provide quiet, smooth operation and stronger acceleration and require less maintenance than internal combustion engines (ICEs).
• Reduce energy dependence. Electricity is a domestic energy source.
• Energy efficient. EVs convert about 59%–62% of the electrical energy from the grid to power at the wheels. Conventional gasoline vehicles only convert about 17%–21% of the energy stored in gasoline to power at the wheels.
EVs have some drawbacks compared to gasoline vehicles:
• Driving range. Range is typically limited to 120 to 240 kms on a full charge although a few models can go 400 to 550 kms.
• Recharge time. Fully recharging the battery pack can take 4 to 8 hours. Even a "fast charge" to 80% capacity can take 30 min.
Batteries for EVs are designed for extended life, and studies by National Renewable Energy Laboratory suggest these batteries may last 12 to 15 years in moderate climates and 8 to 12 years in severe climates. However, these batteries are expensive, and replacing them may be costly if they fail.
