To be kicked

In recent years, new energy vehicles, which have been very popular, are also relatively popular. Many people have also bought new energy, including pure electric power and hybrid fuel electric power. In general, batteries are widely used in automobile energy consumption.

When it was not popularized, the battery was only used for ignition, and the other was lighting. There was nothing else about the battery. Now the battery has been used as energy to supply electric motors to drive cars, which is really a new revolution.

But is that success? Personally, I have always held a skeptical attitude. Of course, it may be that my own insight is not deep and I stay on the surface.

For new energy, I think the biggest problem is the endurance, which is the same as electronic products. For example, when a large screen mobile phone comes out, the power consumption is terrible, and the mobile phone may need to be charged N times a day. But mobile phones can play while charging! What about cars? Can the charging pile follow you? So during the charging period, you can't run. Can only wait at the charging post obediently!

One day, I accidentally saw the official website of a Peng car and looked at the battery life. It was just driving in the urban area. See the following figure:

It can be seen that when the outdoor temperature is 20 degrees, the vehicle speed is 100km/h (more than that on the highway, calculated according to the average speed), the battery's endurance is 300km. I have not returned to my hometown yet, so I have to charge half way early. How long will it take to charge? Semih. an hour?

If the temperature is assumed to be 10 degrees, the endurance will decrease. Although it is not much, it can be seen that it has a lot to do with the temperature. What is the endurance if it is below zero N degrees in the north? What about battery life??

Of course, I still think hybrid technology can be considered, but at present, Toyota is said to be doing a better job in hybrid technology, which is just said to be bad. At least it can be driven by fuel. After all, it takes only a few minutes to fill a tank of fuel, although environmental protection is not as good as new energy. However, new energy needs electricity. Where does electricity come from? Wind power generation? Hydropower?? Or nuclear power generation???

Therefore, those who dare to buy new energy are either interested in subsidies, the so-called licensing policy, or have too much money. I wonder what kind of new energy you bought?
