In the current era of scientific and technological development, science and technology has become saturated, although there are many technologies still under development, but relative to the civilian, speed technology is enough to use. In terms of the development of automobiles, the speed and performance of the vehicles have been constantly improving, but the fuel used is oil. Oil is not only non-renewable resources exhausted without getting, but also not clean energy, very environmentally friendly, the current development of science and technology must pay attention to environmental protection, so in this case new energy vehicles appeared. But are new energy vehicles really good?

Advantages of new energy vehicles
Many car owners can't wait to buy new energy vehicles when they go online. Many people also expressed the advantages of new energy vehicles, some car owners said so, new energy vehicles whether they are uncomfortable to buy, because ordinary fuel vehicles are too polluted air, for new energy vehicles such as no pollution of the car, they naturally have to support this aspect, but also said that their efforts can not change the overall situation, I hope that everyone can buy and sell new energy vehicles like him, which can ensure today's air quality.
Objectively speaking, the new energy vehicle is driven by electricity, the performance is certainly very high-end, relatively quiet and comfortable when driving. The most important thing is that you can save a lot of oil money without refueling, the use and discharge of oil are unreasonable, and the advantages of such a tram are very large, which is very in line with the strategy of sustainable development.
Disadvantages of new energy vehicles
However, some car owners said not to believe the results of any brain test, or to use the instructions to see, first of all, this owner bought a Tesla new energy vehicle, at the beginning of the use is quite good, minutes can crush the oil car, do not need to refuel very comfortable. But this is only one side of the word, although many trams do not need to refuel, but the battery life is not very long, often do not replace can also be but need to spend money to maintain, otherwise the battery of this new energy vehicle is very unsurable, so many times the owner of the new energy vehicle is always concerned about the battery situation.
Secondly, the maintenance fee will be very expensive, if there is a car broken, simply repair it, but if the new energy vehicle is broken, it needs to be done, the electronic components of the battery are very difficult to engage, and it may be necessary to change the battery at every turn, change the whole, who can stand it.
The last is the retention rate, to know that the battery is the lower the service life, so compared to the oil car is more unprotected, many want to buy second-hand car owners see such a new energy vehicle is generally difficult to choose to buy. If it has been used, the battery life will be a problem, that is, the more you open the road, the less you can take, which is very unreasonable. In just two years, the tram's endurance can be cut in half, and the price will soon be cut in half.
Problem charging
If the oil truck will choose to refuel and replenish fuel at the gas station, the large number of trams will eliminate the old oil truck, there may be many gas stations that will be eliminated, Sinopec is a central enterprise, it is impossible to eliminate. And if the tram needs a charging pile, if it is set up at the parking place, it will not be charged, or will it be a charging station with centralized charging? The most critical thing is that charging is actually a relatively slow thing, but also very inconvenient, if there is no place to charge the tram, the tram will not be able to continue to run.

summary
In fact, new energy vehicles have advantages and disadvantages and are very obviously complementary to fuel vehicles. As long as the problem of battery materials can be solved, it is estimated that the problems existing in most new energy vehicles can be solved, otherwise the number of new energy vehicles will never be too high.
