That combustion engines have their days numbered in the automotive industry is something that is practically taken for granted. What is missing, yes, is to put a date. And some experts believe it will be sooner rather than later. Therefore, for those who still resist opting for electric vehicles because they are convinced that, on asphalt, there is nothing better than burning gasoline; or for those who have already moved from one model to another, but are still not 100% sure of having made the correct decision, we list the main reasons why an electric motor exceeds a combustion one.
1. Batteries: heavy but flexible.
The weight of the batteries, which is unquestionable, is one of the points that are often argued against electric vehicles, compared to those that are powered by internal combustion engines. However, although the weight is there, there are also the advantages that derive from the flexibility of the batteries.
Thus, for example, if you opt for its central placement, you get in return a good distribution of weights in addition to greater agility of the vehicle, basically because of its low polar moment of inertia. To these strengths can be added others, such as those provided by a flat battery located along the bottom of the tourism. In this case, the maintenance of the low center of gravity would be added as positive aspects. In addition, with this configuration the airflow under the vehicle would help to cool the battery.
2. Acceleration control.
A 50% acceleration translates, in an electric vehicle, into 50% power. This, which seems obvious, is not so obvious because in turbocharged cars it will not always be the case. Although it is true that, in them, with an acceleration of 50 you can obtain a 100, it is also true that the result can be much lower.
Thus, in the face of uncertainty, the electric vehicle offers security at this point: you will receive exactly what you are demanding from the acceleration pedal. Basically, with them you can choose more exactly how much power you want at any given moment, something that is more difficult in cars with a combustion engine, which are much more sensitive at low acceleration.
3. Fade-free brakes.
Although electric vehicles are not exempt from brake fade, it is much less common than in vehicles with a combustion engine. Why? In essence, because mechanical brakes are used much less.
Thus, for example, when braking dry with an electric vehicle, it is possible to use the battery as a generator and thus avoid overheating the brakes. This translates, among other things, into less rotating mass, less unsprung mass and, finally, in the possibility of using smaller brakes and less brake-dependent driving which, in an electric, will be more durable.
4. Instantaneous torque.
One of the main strengths of electric vehicles, especially visible in urban driving, is their ability to reach maximum torque from 0 revolutions per minute (RPM). When you brake, start, brake again, start again (classics of urban driving), that’s when you really notice this advantage. Thus, depending on the set-up, the electric vehicle will respond with good acceleration and, when the speed and RPM increase, the torque will decrease.
5. Simplicity of transmissions.
Another of the strengths of electric vehicles is that it is not necessary to have multiple gears or complex transmissions. This translates into very simple configurations – this is the case, for example, in Formula E vehicles – that favor lower weight, greater simplicity and, with all this, superior confidence.
At this point the door can be opened to the eternal doubt: manual transmissions or dual-clutch transmissions? And, here, there are tastes for everything. One of the most frequently used arguments is that driving with manual gears is more dynamic. And, although it is true, it is also true that more and more advanced vehicles are opting for the semi-automatic gearbox. The main reason is none other than the less time required for the change, thus moving towards faster cars and, in the case of electric cars, as has been seen, with nothing to envy those that have combustion engines.
Everything results in greater ease of maintenance.
