Electric cars are practically a reality in everyday life in many countries. In the US there is even an incentive for those who buy these models, and there are not a few. Right here in Brazil, we already have electric cars that run in big cities and highways. But there is still a lot of doubt on the subject.

Therefore, we conducted an interview with Marcelo Paranhos, mechanical engineer, specialist in project management, master in Educational and Technological Scientific Training and coordinator of postgraduate courses in the area of Engineering and Technologies in uninter, about the subject. Check it out below:

1. What is an electric car basically?

Like combustion-powered cars, electric cars are self-driving, non-autonomous vehicles used to transport goods and people. However, it has fewer production components than the combustion-powered car.

2. In practice, how does the electric car work in terms of consumption in cities and road?

It really depends on the brand of the electric car. On average, we can estimate that to travel 100 km a combustion car consumes an average of 10 liters, while an electric car consumes 20 kWh. Comparing the value of kwh with that of fuel, we can assume that paying the value of kwh is much more advantageous than gasoline.

3. Can you have an electric car in a city that doesn't have one? supply location?

The range of an electric car is between 200 and 400 km and depends on electricity supply points.

4. Can the car be refueled at home? And if you can, it's Do I need to make any changes? The energy consumption increases by how much?

Yes. It is possible to install a residential charging point at home, however, it is necessary to pay attention to some details: the cost is not low or popular to acquire the equipment and carry out the installation (it can exceed R$ 10,000), it is necessary to have a power source of high voltage on the wall and skilled labor.

5. Are electric cars 100% on energy or do they still use fuel?

There are two models: hybrid cars (which use fuel or electricity) and fully electric cars.

6. Some people say that electric cars are just for the high class. Is this really a reality in Brazil?

I believe that the mass use of the electric vehicle still has some challenges, mainly in relation to the sale price, which can vary between R$ 100,000 and R$ 150,000.

7. One of the points regarding sustainability: The statement that cars electrics are not sustainable due to the large expense in their manufacture and parts that pollute, is it true?

The cost to manufacture electric cars is lower than to manufacture the combustion car. However, the moment of great interest in this type of vehicle has raised prices.

8. Does Brazil have a policy for those who buy electric cars?

Yes. There is currently a project in progress that institutes an electric mobility policy with guidelines that encourage the acquisition, installation of refueling points and conversion of vehicles with combustion engines. This is the bill 2156/21.

9. Do you think that with all the crisis we are currently experiencing with the War between Russia and Ukraine, we will have an acceleration in the developing and manufacturing more electric cars?

It may be so, but I believe it will not be a significant acceleration. The war in Russia can in a way accelerate discussions on the subject, but the mass use of the vehicle will be a transition process, if the product is really sustainable and significantly good for the environment, and if it also passes through popular approval. .
