Electric Cars

Today I will focus on Cars that run on electricity as part of my series on alternative fuel.

Electric cars can also fall under the scope of the hybrid alternative. Vehicles using both electric motors and ICEs (hybrid electric vehicles) are examples of hybrid vehicles. Hybrid vehicles with batteries that can be charged externally to displace some or all of their ICE power and gasoline fuel are called plug-in hybrid electric vehicles (PHEV), and are pure battery electric vehicles (BEVs) during their charge-depleting mode.

Using regenerative braking, a feature which is standard on many electric and hybrid vehicles, a significant portion of the energy expended during acceleration may be recovered during braking, increasing the efficiency of the vehicle.

Vehicles that run on electricity produce no tailpipe emissions. As a matter of fact, the only emissions that can be attributed to electricity are those generated in the production process at the power plant. Electricity is easily accessible for short-range driving.

Electricity used to power vehicles is generally provided by the electricity grid and stored in the vehicle's batteries. Home recharging of electric vehicles only takes plugging them into an electric outlet.
Under the hood, there are a lot of differences between gasoline and electric cars:

* The gasoline engine is replaced by an electric motor.
* The electric motor gets its power from a controller.
* The controller gets its power from an array of rechargeable batteries.

You can replace lead-acid batteries with NiMH batteries. The range of the car will double and the batteries will last 10 years (thousands of charge/discharge cycles).
