These things about new energy vehicles

Nowadays, new energy vehicles have made a lot of progress than before, so we can't always look at them from the previous perspective.

Just like a mobile phone, a few years ago, you never imagined that a few years later, the mobile phone would realize 120W fast charge and 120Hz high brush. ...

Or "Oh, you can charge wirelessly without a plug". You certainly didn't realize this at that time, and now the charging speed has really improved a lot.

Where new energy vehicles are not good, they have all been improved.

The charging speed is greatly improved.

Many people talk about new energy vehicles. Isn't this trouble? Not as convenient as a gasoline car. Look at people, the pipe "dua" is installed, and you can go after 5 minutes of filling up.

Charging is fast now. Most new energy vehicles can be charged from 20% to 80% within 1 hour, which is a common 60kW DC fast charging pile in China.

For example, GAC GE3 can charge from 20% to 80% in 30 minutes under the charging power of 530,6060kW.

BYD Tang EV600 and Geely Emgrand GSe can charge 30% to 80% in half an hour. Is this the kung fu of playing games?

The faster charging speed also makes the charging experience of the owner better.

China Charging Alliance and Kuaidian released a White Paper on Charging Behavior of Electric Vehicle Users in China in 20021year, which contains data that users' satisfaction with charging experience has exceeded 70%.

The battery warranty policy is also improving.

In addition to charging, new energy vehicles also have a big problem, that is, the cost of battery replacement is high.

But in fact, people who have bought new energy vehicles know that the battery warranty policies of major car companies are getting better and better.

As far as time is concerned, national policies are influential and are constantly making these things longer.

For example, on 20 10, the Ministry of Finance, in conjunction with other departments, issued the Notice on Launching Pilot Subsidies for Private Purchase of New Energy Vehicles.

It requires car companies to provide a warranty of not less than 5 years or 65,438+10,000 kilometers for key components such as power batteries.

That's 10, right?

In 20 15, the Ministry of Finance and other four departments jointly issued the Notice on Financial Support Policies for the Promotion and Application of New Energy Vehicles from 20 16 to 2020, extending the battery warranty period to 8 years or120,000 kilometers.

Now most car companies have a battery warranty time above this requirement.

For example: Tesla Model 3, the warranty period of high-voltage battery is 8 years or 1.6 million kilometers; BYD guarantees the batteries of non-operating vehicles for life, and the core parts are guaranteed for 8 years or 654.38+0.5 million kilometers.

It is very likely that the car was changed at that time, and the battery warranty period has not expired. It's a bit like: all the functions of the mobile phone are fine, all of them are fine, and a new mobile phone has been replaced.

Where new energy vehicles are good, there are actually shortcomings.

All the above are places where new energy is improved, and they are all good. So, buying new energy is still a headache or a fly in the ointment.

Although the electricity bill is low, the purchase cost is high.

First of all, everyone thinks that new energy vehicles are cheaper than oil vehicles. In fact, they are not as cheap as expected, and the cost is not low.

When you buy a car, what you consider most is the range of 50,000 to150,000, right? The price of new energy vehicles will be much more expensive for the same car.

For example, BYD Qin Pro, the official guide price of gasoline version is at least 79,800 yuan, and the lowest price of pure electricity is 654,380+049,900 yuan, which is more than 70,000 yuan directly, almost the distance of a car.

Another example: Changan Yidong, the official guide price of the gasoline version is more than 60,000 cheaper than the pure electric version, which is not a product of the same price.

There are many problems in installing charging piles.

Moreover, the charging speed of new energy vehicles has indeed become faster, but when installing private charging piles, it is not as easy or as fast as we thought.

Now you need to provide three certificates to apply for installing private charging piles. In addition to the simplest personal identification, you also need proof of parking space use. Must have a fixed parking space property right or a long-distance parking space use right of more than 1 year.

In addition, you need to prove that the property allows construction and the property allows installation before you can install it. Many friends who work in first-and second-tier cities and have not settled down are stuck here, which is very uncomfortable.

And even if there is a parking space, if the residential property does not agree, it will not work. It is not easy to get people to agree.

Wu said in the paper "Development Status and Strategy Analysis of Private Charging Piles" published in the magazine "Industrial Innovation Research".

When installing the charging pile, the owner needs to go through the steps of preparation of installation materials, installation of power supply bureau, on-site investigation, scheme confirmation, installation of charging facilities, installation of electric meters, and acceptance of power connection.

Listen to such complicated installation steps, if something goes wrong, for example, there is no reserved meter box, wiring is too difficult and so on. In the end, it may not be installed.

The problem of battery life reduction has not been solved.

Finally, although the battery warranty of new energy vehicles has improved a lot, the problem of battery life still exists. Especially in the low temperature environment, the battery life is quite powerful.

Yang Jiaoyuan, Wei Song and others published a paper "Analysis of the Influence of Low Temperature on the Performance of the Power Battery System of Pure Electric Vehicles" in Shanghai Automotive magazine, which said.

At-10℃, the energy of the power battery is 94% of that at room temperature of 25℃, which sounds ok, but under the same working conditions, the cruising range is only 68% of that at room temperature.

To put it simply, those who used to run 300km can only run 200 km now, 180km.

New energy vehicles have made great progress, but there is still a long way to go.

Generally speaking, although new energy vehicles have made great progress, there is still a long way to go to satisfy all parties.

But it is also a good opportunity for domestic cars to overtake in corners, because everyone is walking slowly, not to say that others are ahead for decades.

Friends who really want to buy, such as charging, price and use cost, should look at the specific model and brand clearly.

Don't promise as soon as you hear new energy; When it comes to new energy sources, they are all cheap. Some are good, some are not; Some are guaranteed, some are not.
