All Electric Vehicles

All Electric Vehicles

All electric vehicles known as EV’s run solely on electricity. These  Electric vehicles are propelled by an electric motor, or in some cases multiple motors that are powered by rechargeable battery packs. Electric Vehicles have many advantages over gas powered vehicles:

  • Energy efficiency: Electric vehicles convert about 59% to 62% of the electrical energy from the grid to power at the wheels—gas fed vehicles convert only about 17% to 21% of the energy from the gas to power at the wheels.
  • Environment Friendly: Electric Vehicles emit no pollutants from the tailpipe or exhaust.
  • Performance Benefits: Electric vehicle motors are very quiet, smooth operation, and provide stronger acceleration. Electric Vehicles also require much less maintenance than gas powered vehicles.
  • Energy Dependence: Electricity is a huge energy source, gasoline on the other hand is much more expensive and quantity limited.

But electric vehicles do currently  face significant battery related issues:

  • Driving range: Most electric vehicles can only drive approximately 150 miles before having to be recharged. Gas powered vehicles can currently drive more than 300 miles before having to refuel.
  • Recharge time: To fully recharge the battery pack of an electric vehicle, it can take from 4 hours up to 8 hours. A quick charge  can take 30 minutes to get the battery back up to 80%.
  • Battery cost: Large battery packs for electric vehicles are expensive, and need to be replaced a few times during the lifetime on the vehicle.
  • Bulk and weight: The electric vehicle battery packs are very heavy and consume considerable space space in the vehicle.

Researchers are currently working on improved battery technologies for electric vehicles, that should increase driving range & decrease charging time, battery weight, & cost. Cross your fingers and hope that they are successful, so that vehicles in the future can be environmentally friendly, and powerful.
