Cctv newsRecently, at the press conference on the development of industrial communication industry in the first half of the year held by the State Council Office, Xin Guobin, Vice Minister of the Ministry of Industry and Information Technology, gave a detailed introduction to the characteristics of new energy vehicles’ power exchange mode when answering a reporter’s question, which was clear in organization and could be called a textbook answer.
He believes that charging and changing electricity are both ways to supplement the energy of electric vehicles, each with its own advantages, its own application fields and consumer groups. At present, although new energy vehicles have made great progress, they are still in the early stage of industrial development. The technical route and business model are still being explored and changed. He suggested that everyone should support the innovative development of new technologies, new formats and new models, encourage enterprises to develop new charging and power exchange technologies, and explore the application of the mode of separation of vehicles and electricity to meet the needs of different markets.
Compared with the charging methods that you know more about, the power exchange mode also has its own characteristics. Xin Guobin can be summarized as follows.
First, the separation of vehicles and electricity can greatly reduce the cost of consumers buying cars.Now it is generally felt that new energy vehicles are relatively expensive, although the state has a subsidy policy. Moreover, the subsidy policy of this country has made it clear that the slope retreat will be completed by the end of this year. Due to the impact of the epidemic, it is decided to postpone the progress of slope retreat, and it can be extended for another period. Therefore, the separation of vehicle and electricity can greatly reduce the cost of car purchase for consumers.
Second, it can increase the convenience for consumers to travel.The time for changing batteries is even shorter than that for adding a tank of oil. Relevant comparisons show that, for example, if the power station is changed now, it takes less than 3 minutes for the car to drive in and out, and it takes 5 minutes or 8 minutes to add a tank of oil. Therefore, changing electricity is actually very convenient as long as you get used to it.
Third, the centralized monitoring, maintenance and management of batteries by battery operating companies is conducive to prolonging the life of power batteries and improving the safety of batteries.Consumers buy new energy vehicles, and many people just drive them, so the care, attention and maintenance of the vehicles are not so timely. In fact, the battery is also a very fragile component. In addition to the battery monomer, there is also the management problem of the battery pack, which requires high technical requirements and needs to be maintained and tested in time during use. Otherwise, there is a great risk during charging and one hour after charging. Once the thermal control and management are not good, deflagration may occur. Even with this problem, the spontaneous combustion rate of new energy vehicles is lower than that of traditional vehicles. Centralized management by battery operating companies can improve the safety of batteries. In fact, it is very important to change the concept. It is natural and normal for traditional cars to go to gas stations to refuel, so it should be possible for new energy vehicles and electric vehicles to change batteries and rent electricity.
The fourth is to use the difference between peak and valley electricity prices to reduce the charging cost.At present, new energy vehicles are often driven home to charge at night and charged at peak hours, so the price of electricity will be relatively high. If a battery operation company manages batteries, it can fully use the peak-valley preferential electricity price to charge, which can reduce the cost of renting batteries.
Fifth, we can consider how much electricity to rent that day according to the daily mileage.At present, the basic driving range of new energy electric vehicles is 400 kilometers, and a set of batteries in a car is six or seven hundred kilograms, which accounts for a high proportion of vehicle weight. In fact, most people don’t travel more than 50 kilometers a day. Imagine that if you want to run 50 kilometers today, you can rent 50 kilometers of batteries instead of carrying 400 kilometers of batteries, so the weight of the car will be greatly reduced and the power consumption will be greatly reduced. For the whole society, if everyone does this, it will be a great savings. If you are worried about how to rent 50 kilometers of electricity, as a battery operating company, you can do it if you want 50 kilometers and allocate 70 kilometers of electricity just in case there is a little problem.
There’s another way,It can solve the problem of difficult construction of charging piles in old communities.Now, there is still a concern for people to buy new energy vehicles. They live in an old community and need to build a charging pile. The voltage load in this community is not enough, so they can’t install it. When the charging pile company wants to install in this community, it encounters some problems, such as insufficient power load. Who will expand the capacity? Who will pay for the expansion? Therefore, it brings a series of problems. The construction of charging piles in old communities is a social problem and difficult to handle. Therefore, if the power exchange mode is adopted, this problem can be effectively solved.
Sixth, the power exchange model can also give birth to some new service formats.Nowadays, express delivery is very convenient. You can get to your side in 10 minutes by making a phone call. If the industry adopts the mode of changing electricity, engages in a tram and swims in the street, whoever proposes to change electricity must ensure that it will arrive within 10 minutes. In fact, there is no technical problem. This may give birth to some new service models.
Of course, there are still many problems to be solved to promote this power exchange mode. For example, the overall design of the vehicle, the battery box should be standardized and unified, there should be national standards, and the battery should also be standardized, whether it is soft or hard, square or cylindrical, the specifications should be standardized. In addition, the plug-in of batteries should also be standardized, which still needs further exploration.
However, from a technical point of view, there should be no major problems. Therefore, in the next step, the Ministry of Industry and Information Technology will continue to vigorously promote the construction of this charging and replacing infrastructure with relevant departments, further improve relevant technical standards and management policies, and encourage enterprises to develop battery replacement models according to usage scenarios. It will also support pilot projects in places like Beijing and Hainan to promote the high-quality development of new energy vehicles.
In this regard, some places are still moving faster, such as Beijing, where enterprises are ready to push this mode of power exchange. In some fields, such as buses in public transportation, some electric buses adopt the mode of changing electricity. In the field of taxis, some have adopted the electricity-changing mode. For example, after the taxis in Beijing adopted the electricity-changing mode, the order-taking rate increased by more than 30%, the driving mileage increased by nearly 30%, and the personal income of taxi drivers also increased by more than 30%.This is a very beneficial model for all parties.
In the next step, relevant departments will actively promote it. Xin Guobin also put forward an initiative. Welcome everyone to publicize these new things and new formats, give them more encouragement and support, let them mature at an early date, and make more contributions to the green development of the whole society.
