Electric Cars: Promises and Pitfalls - Tech News #4

In the last few years, electric cars have come a long way and now appearing to be a viable alternative to the fossil fuel powered cars. Electric cars come with the promises of greater efficiency, lower running costs, zero emissions, lower noise levels, lower maintenance costs, and improved safety.

 Promises and Pitfalls

While the benefits of electric cars are many, we need to be aware of the potential pitfalls such as low driving range in a single charge, long charging time of batteries, number of charging stations, and the battery life itself. We should also make sure whether we are adequately prepared for such a huge transformation from fossil-fuel powered cars to battery powerd cars.

How electric cars work?

Electric cars convert the energy stored in batteries using electric motors into the mechanical energy of the wheels which move the cars. This is principally different from how a gasoline powerd car works. In electric cars, an electric motor does the work of the internal combustion engine.

Hydrogen fuel-cell powered cars: An alternative electric vehicles technology

In Hydrogen fuel-cell cars, the energy stored in hydrogen is converted into electricity using fuel-cells which is used to power the electric motors of the cars. The only byproduct in this process is water and it is environment friendly.

Unlike the electric cars which take some time to recharge, the hydrogen fuel-cell powered cars can be refueled with hydrogen in very less time.
