GASOLINE Vs ELECTRIC

AIs it better to choose an electric car or a fuel-powered car? Here are some key questions to ask yourself: How much do you drive every day? Do you have access to charging stations or refueling stations? How important is reducing your environmental impact to you? What is your budget?

ARE ELECTRIC CARS GOOD FOR THE ENVIRONMENT?

Electric vehicles improve air quality because they do not emit CO2 and also reduce noise pollution. However, to ensure that they are truly sustainable, all stages of their production must be examined.

EXTRACTING MATERIALS TO BUILD ELECTRIC CARS

Batteries are composed of:

Lithium

Nickel

Graphite

Manganese

Cobalt

A great deal of energy is required to extract these materials.

The false myth of electric cars

No, electric cars do not explode more than gasoline-powered ones. It's a myth that electric vehicles (EVs) are more prone to explosions or fires than gasoline-powered cars. In fact, the data suggests the opposite. Gasoline-powered vehicles are significantly more likely to catch fire due to the combustibility of gasoline, which is inherently more volatile than the materials used in EVs

EV fires represent a very small fraction of the total fire incidents—around 0.02%​ but is it harder to turn it off

Problems with electric car fires

A fire in an electric car is generally more difficult to extinguish than one in a gasoline car. This is mainly due to the nature of lithium-ion batteries, which can continue to burn and reignite for longer, unlike the fuel in a gasoline car, which can run out more quickly. Electric car fires require specialized techniques and greater attention from rescuers.

Battery disposal

• Safe removal

• Transport and storage

• Recycling

• If damaged...

The whole process is governed by strict environmental regulations to ensure safety and reduce ecological impact.

Nickel

• Nickel is a hard, lustrous, silvery-grey metal.
• It has good resistance to corrosion and oxidation

Transport and storage in authorised centres to avoid environmental risks. Batteries are stored in special containers.

Manganese

• Is white-grey metal similar in appearance to iron.
• In batteries, manganese increases stability and the ability to store energy.

• Is d

Safe removal of the battery from the vehicle by specialised technicians.

Recycling to extract precious metals such as lithium, cobalt and nickel, because they are rare materials

Cobalt

• it is a blue and very hard element.
• Cobalt favoring very rapid recharges

Litium

• It is extracted from minerals such as spodumene and from salts in water.
• Lithium is a very dangerous and polluting material

Graphite

• Graphite is matt black in colour, and resistant to heat and corrosion.
• It is a good conductor of electricity

If damaged, they are disposed of in specialised facilities to avoid contamination.
