It can be said that as long as the battery problem is not solved, electric vehicles cannot completely replace fuel vehicles, which is basically the most difficult problem in the whole electric vehicle industry.
How do these car manufacturers want to solve the battery problem?
Tesla's idea is to charge quickly.
So we have been developing fast charging technology!
But Wei Lai doesn't think so. What they want to do is change the electricity!
As the name implies, when the car is running out of power, drive to their power station and directly replace it with a fully charged battery. Here's a question:
Is this power exchange technology promising?
Will Tesla be unable to keep up with the pace in the future because it does not pay attention to this field?
Let's talk about the benefits of changing electricity first!
First of all, save money-if you buy an electric car now, the battery is very expensive. After several years of use, the battery is aging, so you can get a new one. You can't get it without tens of thousands of dollars. This is a high cost!
But if you change the electricity, you don't have to bring a battery when you buy a car. Just buy a car and rent a battery at the power station. Moreover, the battery will be upgraded in the later stage and its performance will be better. You can also enjoy the latest achievements at any time, otherwise you can only watch them.
Second, it is fast. Now charge quickly. If you want to fill it, it will take dozens of minutes anyway, right?
But changing electricity is different. The battery, cracking, dismantling and unloading will be over in three to five minutes.
After you change it, you drive away, which is full of electricity;
Moreover, third, the burden on the power grid is small, especially in some old communities.
Now these charging piles have hundreds of kilowatts of power!
Then, these air-conditioned refrigerators in our family have a power of one kilowatt, which is a big item. If the power of the reactor is fast, it will support hundreds of air conditioners, and the power consumption is still unstable. At eight or nine in the evening, everyone will concentrate on charging, and no one will use electricity in the middle of the night.
The burden on the power grid is relatively large, but there is no such problem when changing power stations, which can be centralized and coordinated, and the power consumption is stable and controllable.
These are all advantages. I think the future seems really good!
But! The shortcomings are also obvious!
The key problem is that the battery specifications are not uniform, and the battery standardization, interface standardization and even battery management system standardization have not been realized. Everyone has their own pattern. And we built a power station, of course, hoping that I have a battery of a specification, and you can change it when any car comes, just like a gas station.
In addition, in general, the investment in changing power stations is large, and the basic investment and battery reserve are not enough. Coupled with the later operating expenses, it must be supported by scale. Otherwise, ten power stations will be built there, and there will be more than a dozen cars that can be replaced on the road. What family can't be destroyed like this!
This is actually the advantages and disadvantages of electric vehicle replacement.
Which direction is the power exchange technology pushed by Weilai VS the fast charging technology advocated by Tesla?
The two are likely to complement each other in the future!
For example, in densely populated cities, changing power stations should be a better way to make intensive and efficient use of social resources and avoid building charging piles everywhere;
But if you want to run a long distance, the charging pile is more suitable, so this matter, in many cases, is not to say whether there is you or not, but to complement each other!
Only by properly solving the battery problem can electric vehicles really change the world as it depicts. ...
Is it possible for Weilai to turn over Tesla by changing the power technology? -Very likely!
When the battery standardization, interface standardization and even battery management system standardization of all brands of electric vehicles are completed, scale effect will be formed. In first-and second-tier cities, the potential for changing electricity will be even greater!
