The favorite argument of fans of electric cars that such vehicles do not harm the environment is simply not true. Of course, such cars do not emit themselves, with the exception of rubbing tires and dust from the brake pads. But after all, many forget about the main thing – electricity, which is really important for the transport of the future. It won't come from anywhere. From an ecological point of view, an electric car is clean as much as the electricity, produced for it.
This general statement is partly correct - but it depends on how to determine the serviceable life. If we consider this concept as a ratio of time that has passed since the production of a car and the timing of its repair, then the electromobiles have more chances to win in this sense.
Now, for example in Europe, the average service life of a car is 18 years. It is too early to say what this indicator will be for electric cars. Nevertheless, the relevant tests of Nissan Leaf, conducted by the ADAC (General German Automobile Club), show that electric cars have good endurance. In particular, although at the end of the five-year test, this Nissan model has lost about 10% of its battery capacity and driving range but otherwise it has proved to be durable and reliable.
Here, as an exception, we can agree without any reservations. Since, in terms of design, electromobiles consist of much fewer parts than petrol-powered cars, maintenance costs are substantially lower.
Manfred Schoch, the chairman of the BMW production council, explains the situation on a very impressive example: "The eight-cylinder internal combustion engine consists of 1,200 parts which need to be connected together, and the electric motor has only 17". The situation is similar with the transmission of electric cars, which has fewer parts, and such vehicles don't have the exhaust system - and we all know that where there are fewer parts, there is less likelihood of breakdowns.
Only tires in electric vehicles wear out faster than in the cars with ICE. The reason is that the thin tires of electric cars are forced to withstand a greater torque and, as a result, they need to be changed after near 15,500 miles on.
To be able to realistically assess the actual risk of fire after an accident, you need to consider the statistics in relation to the proportion of electric cars in the fleet of the country. So far, there are no certain statistics on such fires, so it is not possible to make any clear statements. However, it is likely that soon the need for such discussions will fall off. The appearance of solid-state lithium batteries on the market is not far off. Such batteries do not contain liquid and are capable of operating at higher temperatures even more reliably. Toyota can become a pioneer in this area - the company can start installing the batteries in its cars as early as 2020.
The last myth for today is not taken, as they say, from the air. So, maximum performance in electric cars can't be received in the constant mode, unlike petrol cars. it's all the fault of electric motors, which, regardless of the load, work with an efficiency of over 90%. The higher the speed of the car becomes, the higher the level of the consumed energy. As a result, the engine and battery become very hot. Therefore, electric cars automatically reduce the performance so that the components can cool down.
