Electric cars: pros and cons

Elon Musk was one of the first to invest in his Tesla, and today there is no manufacturer that does not include at least one model in its catalog: Electric cars are now a constantly growing reality, and the future of the automotive industry will do nothing else. than to confirm this trend. However, not everyone is yet convinced to abandon fossil fuel-powered means of transport and switch to more sustainable cars. The reasons for this reluctance? A recharging system that is still too little prevalent, the fear associated with an autonomy that is thought to be insufficient, and the small tendency to change its habits. So let’s try to understand something more about their function, so the choice to buy them or give them up is really conscious.

What are electric cars

By electric car we mean a car that, instead of being equipped with a classic petrol-powered engine (which also has hybrids), uses a rechargeable battery to move. These are therefore the models that you can now more and more often see stopped at the charging columns, and which give very little noise when running on the street. They are certainly not new in the car world, but lately they have started to spread enormously thanks to a much greater autonomy than the first examples (we are also talking about 600 kilometers with full tank) and the implementation of a system of charging stations very more widespread throughout the territory. Not only that, government incentives have also contributed to their proliferation: in recent years, the government has actually allocated large sums of money to enable citizens to buy one at an affordable price. Moreover, this was one of Italy’s attempts to try to respect the goals of sustainability and environmental awareness that Europe has imposed.

How electrical machines work

In electric cars, the energy needed to produce the movement of the vehicle comes not from fossil fuels, but from an electric motor, actually equipped with batteries located either under the car or in the trunk. These are usually lithium ions, which allow faster recharging, longer life and longer autonomy combined with more compact dimensions: A medium-capacity battery can actually hold up to seven thousand cells and is equipped with a refrigerant that prevents overheating.

Seen from the outside, however, the traditional and electric cars are practically identical if it were not for the absence of the exhaust pipe in the latter. The differences are all under the body and can be summed up in a single element: the inverter, which is the entire car’s command center, as it is able to transfer energy from the batteries to the engine. It is the latter that transfers energy to the wheels by acceleration and accumulates it during deceleration and braking. Furthermore, the gearbox and the clutch are missing, because on the one hand the motor guarantees the drive torque independently, and on the other hand the transmission of energy stops by itself without having to be interrupted. One of the few electric cars equipped with two gears is the Porsche Taycan: for all the others, however, it is the manufacturer himself who limits the speed.

How to recharge an electric car

One of the biggest doubts that blocks many people from buying an electric car is the autonomy, not so much because it is actually low (almost always it is sufficient for normal use of the car), but rather for a charging method that many consider . inconvenient or not very functional. As mentioned, the pillars are much more widespread today than a few years ago, but still there are still too few not to notice a difference between the more classic service stations. To recharge an electric car, however, there are two useful ways: the towers installed in the area or the normal socket at home, which must be made compatible via an adapter, which – as a rule – is delivered in the purchase phase. The latter, however, for obvious reasons fails to deliver the same performance: fast recharging takes place in a few hours, but reaching 100% can take up to a day. Not only that: If you do not have a garage or parking in the immediate vicinity of the house, it is completely impossible to get on with home charging.

Pros and cons of buying an electric car

The time has come to draw conclusions: what are the pros and cons of an electric car? The first certainly include reduced electricity costs, not having to pay stamp duty and the possibility of taking out reduced insurance coverage (at the discretion of the individual companies). Furthermore, with an electric car you can access the cities’ limited traffic areas without the risk of fines, and you can very often make use of concessions for the purchase and installation of a pillar in your area. Finally, they allow you to drive a vehicle with less impact on the environment, as long as the energy used comes from renewable sources and not from fossil fuels. However, the disadvantages include very high maintenance costs, poor comfort – at least for now – when charging and insufficient autonomy for longer journeys (from north to south in Italy or vice versa). In short, the purchase must, as always, be assessed on the basis of one’s specific needs and the individual’s habits.
