Jinan Daily reported that at noon that day, the two sides signed a comprehensive strategic cooperation framework agreement in Shandong Building, "to start the operation of Geely intelligent charging and replacing power station and urban travel project, and the construction of Geely intelligent new energy automobile factory project." But the mainstream auto media didn't publicize it.
In the afternoon, a few media, including journalists, were invited to visit the demonstration station for power exchange. However, based on the judgment of "low-key must have great events", the reporter is very curious about what "material" is behind the start of Geely Power Station.
Quick, not just quick.
Just one word. Come on. This is the reporter's feeling about Geely Technology's 90-second power exchange mode, so for its power exchange efficiency, Geely uses the word "extreme speed" to define the mode of power exchange within 90 seconds, without getting off the bus, and also adopts intelligent unattended design, and the whole process of power exchange is carried out automatically without manual assistance.
This power exchange station is the first intelligent power exchange station independently developed by Geely Technology. It adopts double warehouse receipt station design and is equipped with 39 batteries. Compared with the reserve of five batteries in Weilai Power Station, it undoubtedly has great advantages in quantity.
In addition, let's take a look at Aodong New Energy, which has the largest number of power stations in China. An Aodong 3.0 power station has 28 circulating batteries, which are changed every 3 minutes and can serve up to 420 times a day. In contrast, Geely still has advantages in quantity and power exchange efficiency.
Wang Zhihai, head of power exchange technology of Geely Technology, said that the power exchange development of Geely Technology Group has been going on for three years. From 20 17, the research and development of power exchange technology platform and vehicle architecture platform began. "We have conducted a lot of market research and analysis in three years and carefully selected the technical route. During the R&D period, the number of participants in R&D exceeded 1000, the investment was several billion yuan, and more than 30,000 related experiments were conducted. Patent/kloc-more than 0/000, this is the real thing.
Wang Zhihai also said that Geely Technology Group's power exchange technology platform has the characteristics of high modularity, high compatibility, high security and high intelligence, which are embodied in the following aspects: it is compatible with all models with a wheelbase of 2700~3 100mm; Advanced locking mechanism design, firm and reliable; Excellent intelligent temperature control system, which can operate normally and effectively in high altitude, high temperature and cold areas; There is a complete three-level fire protection system, which effectively avoids the spontaneous combustion risk of traditional new energy vehicles when charging.
In addition, Geely has also built a 5G cloud platform from the car to the station and then to the cloud, which enhances the experience through the interconnection of stations and monitors the status of each battery pack through the interconnection of stations and clouds. Geely's intention to create a new benchmark in the power exchange market is obvious.
"From the beginning of changing power stations, we put safety first." According to Wang Zhihai, this system has been tested in safety, durability, high temperature, cold and plateau. Among them, 30 prototypes were put into collision safety test, and more than 100 vehicles were put into test before and after. Completed more than 100 vehicle-level tests and more than 5,000 system and component tests. The cumulative mileage of vehicle performance and reliability test is * * * 1.5 million kilometers.
In the design of the core battery pack, Geely adopted a flat standard battery design consistent with the current mainstream platform design of pure electric vehicles in the market, and the service life of the battery can reach 8 years and 600,000 kilometers.
The design of locking mechanism for power exchange, including brand-new quick water exchange connector and electric connector, also fully considers safety factors. The durability test of the power exchange lock body and the quick water exchange connector has been completed for more than 16000 times, and the durability test of the system structure has exceeded 800,000 kilometers, which is equivalent to the service life of the whole vehicle 10 year, which fully verifies its reliability.
Geely Technology also said that a brand-new power exchange platform architecture has been developed for this power exchange mode. The architecture covers power exchange technology platform, vehicle architecture platform and big data operation platform. And for the first time in the industry, it has realized the operation of changing power stations, trams and electricity in industry consolidation.
Wang Zhihai said that he is in charge of this technology, but it is not clear whether this power exchange mode is free or charged. However, it can be referenced that Guangzhou Aodong Power Station, which serves Beiqi EU series vehicles, charges taxi drivers 0.33 yuan per kilometer for electricity exchange, and can actually travel more than 200 kilometers with one charge. In 33 yuan, the cost per 100 kilometers is slightly better than the fuel car when the oil price is 5.45 yuan/L. ..
In addition, Maple Leaf 80V, the first B-class battery replacement model of Maple Leaf Motor, which was seen in the afternoon, adopted the business model of separation of vehicle and electricity. In other words, buy a car and rent a battery, and the battery will be settled separately. An engineer vividly compared to the reporter, "just like the liquefied gas bottle we used before, you just need to take a breath and leave the cylinder alone." Gas cylinders are regularly tested by liquefied gas companies. "
Incidentally, the 80V looks like Geely Cargill, with a body size of 4706x 1909x 1699mm and a wheelbase of 2807mm. Like Cargill, it is a standard B-class MPV. However, this power-changing MPV is a 5-door and 5-seat online version, which enters the network for car operation.
Power conversion mode is restarted.
The power exchange mode is not unique in these two years. There was a wave of operation "power exchange mode" in the last round, but it was questioned. This time, it returned to the new infrastructure of the new energy industry and became a key area in the new infrastructure project.
In May this year, the power exchange mode was written into the 2020 government work report for the first time, expanding "building charging piles" to "adding charging piles, changing power stations and other facilities". At the press conference of the State Council Office on July 23, the Ministry of Industry and Information Technology made a detailed positive interpretation of the new energy exchange model. This also means that the power exchange mode has been officially promoted through national policies.
"Spring River Plumbing Duck Prophet", the actions of car companies naturally follow. In addition to Weilai and Geely, recently, the newly independent Changan New Energy established the Chongqing Power Exchange Alliance, and formally signed a contract with Aodong New Energy to serve Changan New Energy E-series cars in the power exchange mode.
At the same time, Softbank Energy also reached a strategic investment cooperation with Aodong. As of June this year, Aodong New Energy has 222 power stations, and the second and third places are Weilai 136 and Hangzhou Botan Technology 94 respectively. Aodong maintained the speed of building two power stations within one month. Weilai is twice as fast. Next year, Weilai will launch the second generation power station, reaching the frequency of a new station 1 day. In addition, Weilai Automobile is also planning to establish a joint venture with Contemporary Ampere Technology Co., Ltd. to establish a battery management asset company.
But the current situation is that the power exchange station and the charging station are not of the same order of magnitude. On July 23rd, Vice Minister of the Ministry of Industry and Information Technology said that at present, 38,000 charging stations and 449 power stations have been built, and various charging piles 1.3 million have been built, including 55 1.0 million public charging piles and 749,000 private charging piles.
According to the planning of Geely Technology, up to now, its power exchange network has been laid out at home and abroad (including Southeast Asia), and more than 1000 power exchange stations have been signed. Chongqing is the first city to start, and Jinan is the second. In addition, Geely Science and Technology Group plans to reach the scale of 5,000 power stations in 2025.
As the largest power exchange station operator in China, according to the planning of Aodong New Energy, it is estimated that it will enter 100 cities nationwide in 2025, build and operate 5,000 power exchange stations, and serve more than 2 million new energy vehicles. It seems that everyone's dreams and ambitions are not small. However, compared with charging piles, the supporting facilities for power exchange in the market are still very scarce. There are still many problems to be solved urgently. For example, the construction and maintenance costs of power stations are much higher than those of charging piles.
Pain point of power exchange mode
Let's take a look at the operation of the power change mode. According to the reporter's understanding and interview, still want to? The direction of b is dominant.
Why do you say that? For example, Beiqi New Energy began to operate and promote power station change on a large scale from 20 18. By the end of May this year, 87 power stations 18000 vehicles have been built and put into operation, with a total of 4.8 million power stations. That is to say, it has not been involved yet? C-end consumers change electricity.
Huang Chunhua, general manager of Aodong New Energy Marketing Center, also said that the power exchange mode has changed from? B To go to? C needs to be gradual. This is easy to understand. One is the standardization of batteries, and the other is the breakthrough of battery technology. With the continuous breakthrough of battery capacity density and cruising range, what is the battery replacement mode? C there is still a long way to go.
After all, the biggest disadvantage of the power exchange mode is that the battery standard is not uniform. It is almost impossible to change batteries between multiple brands, which is a "beautiful plan" for everyone in the long run. Of course, at present, the power exchange mode still has opportunities to grow in public transportation fields such as bus, taxi and online car rental. The step of Geely Technology is also: "The first step is to solve the pain points of operating vehicles first, and then change the network layout. After that, vehicles at the C end can join. "
In addition, according to relevant surveys, in Beijing, the service radius of Beiqi New Energy Power Station is 2.53km in the urban area and 5.6km in the suburbs, which is convenient for users to get to the nearest gas station. Obviously, for? B is more suitable for the business model of power exchange, which has been recognized by the industry.
Cui Dongshu, secretary-general of the All-China Automobile Federation, also made it clear to reporters that the future power exchange mode will not become the mainstream. However, the incorporation of the power exchange station into the new infrastructure will strongly promote the development of power exchange in public areas such as taxis and online car rental.
In addition, the reporter once took a taxi and met a driver of Cao Cao's car. When chatting, he talked about the mode of changing electricity. He made a few very pertinent remarks. "The problem of the power change mode will definitely not be seen at first, but after the traffic comes up, the problem will definitely be exposed. Just like mobike at the beginning, how good he said at first, and then there were more cars, right? "
At present, Geely's power exchange efficiency can rival or even surpass fuel vehicles in terms of convenience. In addition, the government hopes to reduce the burden of urban power grid through distributed energy storage. In addition, the energy efficiency of the power station is more than 50 times that of the charging pile with the same floor space.
Moreover, the reporter believes that one of the ideas of Geely Technology is very good, that is, the concept of sharing platforms and technologies, and fully opening up the power exchange technology platform, vehicle architecture platform and big data operation platform of major enterprises in the industry. The ideal result is to realize the establishment and unification of national and industrial standards for power exchange mode.
However, although the power exchange mode has many advantages, at the moment when the power exchange mode is restarted, the reporter still hopes that the new form must be based on rational market and user considerations, rather than rushing headlong into it and sighing.
