It is difficult for pure electric vehicles to become the mainstream in the market for at least 20 years.

Recently, the master saw two such news: after 2020, China will no longer approve new fuel vehicle companies, and Germany has decided not to build new fuel vehicle manufacturers. From the outside world, this may be just two policy news with similar contents, and it is no big deal.

But in fact, from the media point of view, these two news convey the same message: the future car market will be dominated by electric vehicles , and fuel vehicles will be phased out in the near future. In other words, in the future, the proportion of pure electric vehicles and hybrid electric vehicles will become larger and larger. Coupled with the recent measures introduced by the country, the average fuel consumption of fuel vehicles must be within 5 liters per 100 kilometers in 2020, which seems to be doomed to the end of the traditional car.

But are you really willing to choose an electric car?

Soft rib of electric car

Electric cars, it seems that they are all good, fast, quiet, no pollution, no need to worry about fuel explosion, even because the electric car is simple in structure, it will not be as small as a fuel car, and because the electric car is simple enough, the future price The downside is also larger. As a new era of car form, it is almost certain that electric vehicles can replace expensive and inefficient fuel vehicles.

But despite the many advantages of electric cars, buying electric cars is not a good idea. First of all, the biggest soft rib of an electric car is not the motor power, nor the appearance of the interior design, but the thousands of batteries that store electrical energy.

Looking at several battery technologies currently used by humans on a large scale, there are two serious problems without exception: low energy storage capacity per unit and serious battery degradation. The unit energy storage capacity refers to how much energy can be stored in a unit volume. From this point of view, all types of batteries currently installed in automobiles are far less than the chemical fuel of diesel locomotives. Under the same volume, the electric car can only run 300 kilometers, and the fuel car can run for more than 1000 kilometers. This also leads to the most important reason why the electric vehicle has a cruising range that is not as good as the fuel car.

The second is battery attenuation. We can use the mobile phone on hand to make a metaphor. Do you think that after a few years of use, the battery will become more and more durable? This phenomenon can also occur with batteries on cars. This has greatly affected the service life of electric vehicles. If the fuel vehicles are properly maintained, there are not many problems in using them for 20 years, but what about electric vehicles?

Can you charge faster?

If the fuel car is out of oil, it is going to be refueled. If the electric car is out of power, it has to be charged. Let's not talk about the size of the charging stations that are rare around the world. We will say this time of "refueling". How long does it take to refuel a fuel car? Everyone knows that it is nothing more than the time to go to the toilet.

But what about electric cars? It is said that the fastest super charging station, it takes ten to twenty minutes to fill a car. If you use a household 220V to charge, it will be charged all night. Just say this charging speed, how does the electric car compare with the fuel car?

In fact, the charging speed of electric vehicles is slow. In the end, it is still a problem of batteries. As long as human battery technology does not achieve a revolutionary breakthrough in one day, electric vehicles cannot be compared with fuel vehicles in terms of practicality.

Breakthrough in battery technology

Therefore, the most important factor affecting the popularity of electric vehicles is the battery. Although battery research and development companies all over the world are working hard, so far, there is no new generation of battery technology that can achieve mass production in a short period of time (Chinese scientists have already researched new batteries in the laboratory).

Therefore, as long as the battery technology does not break through the day, it is recommended that you choose a fuel car. According to our estimation, in the next 20 years, the absolute mainstream of the world's cars will still be fuel vehicles.

Bin Blender Equipment

The bin blender machine can execute automatically raising, blending and lowering tasks. One main machine can be configured with multi-bins, So variety blending can be satisfied, consequently it is considered as the ideal blending equipment in pharmaceutical industry. It is widely used in chemical, foodstuff industries, etc.
