What constellation is 52 1? Why is it still so difficult to charge?

Author: Dkp

In 2022, China's new energy vehicles continued to develop rapidly, leading the world for eight consecutive years. At the same time, the number of new energy vehicles in China has reached an unprecedented scale.

According to the data of the Ministry of Public Security, by the end of 2022, the number of new energy vehicles in China had reached 1 365,438+million, accounting for 4. 10% of the total number of vehicles, an increase of 5.26 million compared with 5,438+0 in 2026 and a year-on-year increase of 67. 13%.

The growth rate of new energy vehicles in China is visible to the naked eye, and the corresponding supporting facilities are also being laid rapidly. However, if you pay attention to traffic news, you will find that charging is still a problem.

According to media reports, during the Spring Festival, a car owner spent 15 hours on the original 8-hour drive, and the extra time was spent on queuing for charging. "On the way home, I charged the electricity three times, and it took about 2 hours to charge each time. It took 1 hour to charge once."

Compared with fuel vehicles, new energy vehicles need longer charging time and more charging frequency under the condition of gāo speed, so it is easy for owners to "get together" for charging. It seems that one of the reasons for this situation is that the number of charging piles is insufficient, but in fact it is not.

The problem of charging difficulty is not the shortage of charging piles.

In 2022, the laying speed of charging piles in China will not be slower than the growth rate of new energy vehicles.

On June 5, 2023, 5438+1October 18, at the press conference on the development of industry and information technology in 2022, Tian Yulong, chief engineer and spokesperson of the Ministry of Industry and Information Technology, said that by the end of 2022, 52 1 10,000 charging piles and power stations had been built nationwide.

Compared with the data released by the Ministry of Public Security, China currently has an average of 2.5 new energy vehicles per charging pile, and this proportion will decrease in 2022.

Obviously, in terms of total quantity, the number of charging piles in China has begun to take shape, and the growth rate is relatively fast. Based on the calculation of 4 hours of single energy supplement for each vehicle, the utilization time of each charging pile in a single day does not exceed 10 hour, and there is still 14 hours of free time in a day.

However, the facts are far from ideal. In actual use, due to the geographical distribution, the utilization rate of charging piles will be very low, and its inherent characteristics will amplify this problem.

Based on the characteristics of new energy vehicles, especially pure electric vehicles, it is necessary to replenish energy frequently in high-speed scenes. Combined with large-scale travel on holidays such as the Spring Festival, it is foreseeable that charging is difficult to queue up; In daily urban scenes, due to private charging piles and travel distance, the utilization rate of public charging piles is generally low.

In this regard, some insiders said that at present, the average utilization rate of urban public charging piles is insufficient 10%, and the utilization rate of highway charging piles is insufficient 1%. It is hard to imagine that this set of numbers corresponds to the 8-hour charging queue during the Spring Festival.

Demand for peak charging is in short supply, and off-peak utilization rate is low. Obviously, it is difficult for charging piles to flexibly meet the needs of car owners. Owl Chezhi believes that the utilization rate of charging piles reflects the needs of car owners to a certain extent, and there are many reasons for the low utilization rate, such as being located in a remote office area far away from residential areas.

Private charging piles are still a problem.

For car owners, the best way to solve the geographical location is private charging piles. However, private charging piles are still an industry problem.

Taking a residential area along the Fourth Ring Road in Beijing as an example, when Owl asked if it was possible to install private charging piles as the owner, the person in charge of the property replied: "At present, our residential area does not support charging piles because there is no parking space." The community was completed in 1992. "The problem of a parking space was not considered when the community was built, and now the parking space of 10: 1 cannot be reached." It is reported that the residential area covers an area of 3 1 1,000 square meters, with 44 buildings and 4575 households.

The property staff also said that "the existing parking spaces in the community were all transformed into de in the later stage, not fixed parking spaces and no property rights."

Fixed parking space is one of the basic conditions for private charging piles. Obviously, more than 4,000 households in this community cannot use private charging piles. When referring to the nearby charging facilities, the property staff said: "Several shopping malls nearby have heard that they can charge." The business circle referred to by the staff is about 2 kilometers away from the community, and the owner has to pay the parking fee of 8 yuan every hour in addition to the electricity bill.

"I haven't seen how to drive a tram. There is a 1 tens of thousands of Tesla that has been parked. It is estimated that the owner does not want to charge. " Pure electric vehicles are a "rarity" in this old community. "There was also a household asking about the charging pile before. Later, he pulled wires from home to charge the car. It was so dangerous that we stopped it. "

Private charging piles are an unattainable happiness for old communities where fixed parking spaces are problematic. Even if there is a fixed parking space, residents in the community are not necessarily allowed to install private charging piles.

The second threshold for private charging piles is the property, or the property is responsible for related affairs. With a fixed parking space, car owners need to worry about another thing-capacitance. The capacity of power grid in Beijing is limited, and rashly connecting charging piles may lead to a large-scale power outage. So this happens because the application of electrified parking spaces was not expected during the construction of the community. Not only fixed parking spaces are difficult to predict, but also electrification of parking spaces is difficult to predict.

The capacity of the community can be improved and increased, but correspondingly, it will involve the cooperation of the property, owners, power companies, fire protection and other parties. The overall operation has a certain threshold and also involves economic costs. At the same time, the property will also face fire problems. Perhaps based on the principle of "don't do it, don't make mistakes", many owners were rejected in communication with property companies.

In addition, there are many problems, such as the distribution of property rights and the maintenance of charging piles. Private charging piles are beautiful, but only a few people can enjoy them.

It is difficult to charge, and things are developing in a good direction.

If there are difficulties, there are natural ways to solve them.

The charging problem of electric vehicles will inevitably affect the enthusiasm of consumers, which is something that vehicle manufacturers do not want to see. Charging, exactly the problem of charging pure electric vehicles, has a solution from another angle.

It is argued that changing electricity is the characteristic of Weilai automobile. Weilai has a slogan, "It is more convenient to power up than to refuel". By the end of 2022, Weilai has built 1 305 power stations in China, of which 346 are expressway power stations.

Recently, Weilai Automobile officially released data. During the peak period in Spring Festival travel rush (65438+1 October13-February 5), Weilai provided over110,000 power exchange services, including over 300,000 high-speed free power exchange services and over 700,000 charging services. Among them, the free power exchange service of expressway reached its peak on June 27, 65438 (the sixth day of the first month), and the number of power exchanges per day reached 23866, and the average waiting time for power exchange of expressway was 13.08 minutes. Compared with waiting for the charging pile to be empty and then waiting for the charging to be completed, changing the electrode greatly saves time and cost.

Although the cost of changing power stations is generally high, its practical application experience can really solve the current charging problem and is also a feasible strategy.

In 2022, a "network celebrity technology" was born-800 V high-voltage fast charging. If the power exchange strategy is another way, then 800V high-voltage fast charging is a direct hit.

Based on mileage anxiety, the battery capacity of new energy vehicles is constantly improving, and how to improve the charging speed accordingly has become a new topic. Compared with 400V DC fast charging, if the voltage of DC fast charging is increased to about 800V, more charging power can be obtained under the condition of constant charging current.

In a word, in the same time, the vehicle equipped with 800V high-voltage platform can charge more electricity than the vehicle equipped with 400V platform, thus shortening the charging time. This can not only solve the problem of slow charging of large-capacity batteries, but also give new energy owners a more flexible way to replenish energy.

This jì technology is widely known with the advent of Taycan, Porsche's first pure electric vehicle. It is regarded as the high-end technology of "Xie Wang Tang Qianyan", but this technology "flew into the homes of ordinary people" in 2022.

At present, this technology has been used in OITA 1 1, Extreme Focus Alfa SHI, Guangzhou Automobile Aian AIONVPlus, Tucki G9 and other vehicles. Although 800V high-voltage fast charging is not unusual enough, the technology will always land. With the fiercer competition in 2023, it is not impossible for this technology to be decentralized to more models.

In addition, the supporting infrastructure of new energy vehicles, mainly charging piles, is still being explored. The China Charging Alliance predicts that the cumulative number of charging infrastructures in China will reach 9.584 million in 2023. Recently, the Ministry of Industry and Information Technology and other eight departments issued a document, directly pointing out that the charging and replacing service system is an important goal of ZH in 2023-2025.

The problem of difficult charging will obviously be solved in the near future.

Write at the end:

Compared with fuel vehicles, consumers have noticed the improvement space of pure electric vehicles in battery life, which is why some consumers do not consider pure electric vehicles for the time being. It is a fact that it is difficult to charge new energy vehicles, and this problem is being optimized. At the same time, it can be seen that this is not a problem faced by an industry alone. From infrastructure construction to automobile technology upgrading, it is a pain point for consumers. Perhaps, things are about to turn around.
