Shanghai Auto Show just announced the ideal pure electric MPV charging scheme. What's interesting?

Ideal has been established for six years, and it is finally going to enter pure electricity. It should be possible this year.

Relying on the single driving form of extended range is unfavorable to the development planning after the brand and will only make the market smaller and smaller. Li's long-awaited pure electric plan should be announced at the Shanghai Auto Show in mid-April. The information currently exposed is that a scheme for charging pure electric vehicles will be announced.

About Li's pure electricity scheme, in fact, it's almost announced now:

The first pure electric MPV may be pure electric MPV, which is code-named "w 01"just like the online exposure; Contemporary Ampere Technology Co., Ltd. interacted with the ideal at the Weibo before, and also admitted that the ideal Kirin battery was pure electricity; Then, in a high-speed service area in Guangdong, the ideal fast-filling pile+charging pile under construction was found. It is a good thing to do pure electricity, which meets the needs of mass consumption. Pure electricity is the mainstream trend in the future. After entering the field of pure electricity, both brands and consumers will begin to care about a problem "endurance anxiety". At present, there are several mainstream solutions, such as ordinary charging piles, high-power overcharged piles and power supply replacement.

The ideal can be brought out now. According to the actual situation, there should be only this combination of ordinary charging piles and high-power super charging piles. What consumers care about should not be how many advanced technologies are covered, but whether this overcharge can be used easily.

Can high-power overcharge solve the pain point?

The construction information now exposed is Chehejia (Dongguan) Energy Service Co., Ltd., a wholly-owned subsidiary of Li. The commencement date of the project is 165438+20221October 28th, and it will be completed on March 3rd1day. The picture shows that the overcharging station has four charging piles, which are expected to be 1 480kW overcharging pile and three 250kW charging piles.

Let's think about a problem first. If charging piles and overcharging piles are easy to use and can perfectly solve the problem of energy supplement, then Weilai is still spending energy on self-research and burning money for covered power stations. What is this for? In fact, if we think about this problem, we can analyze that if we have the ability, ultra-fast charging is definitely not the optimal solution of the energy supplement scheme. At present, the most suitable for pure trams to replenish energy is definitely a more efficient power station change. Leave after a few minutes of full charge, without spending time and cost. The whole experience process is very close to the experience of adding a tank of oil to a fuel car.

Is the technology content of over-poured pile high?

At present, rapid filling technology is not uncommon, including Weilai, Tucki and Tesla. , choose this quick pile filling scheme. To put it bluntly, the fast charging pile means that the cable can bear more power output, thus improving the charging speed of the vehicle and shortening the charging time. However, this high-power output will not be maintained all the time, and the charging capacity of the battery should be considered, so the slogan "X minutes, XXX kilometers to charge" is used instead of the propaganda slogan "X minutes, fully charged".

Then, it is not known whether the ideal fast filling pile is liquid-cooled or water-cooled, and the specific details will not be mentioned. However, the high probability should be the liquid-cooled charging line. In terms of heat dissipation capacity and external environmental impact, liquid-cooled cables are superior to water-cooled cables. Tesla's V3 fast-filling pile adopts liquid cooling module, which can also be used under extreme cold test at plateau. Secondly, during the Beijing Winter Olympics, liquid-cooled modules were also used in the fast charging piles of some charging stations.

Then, the ideal plan is to invest 654.38+0 billion yuan to build 3000 overcharged stations before 2025. These overcharged stations are expected to be built in expressway service areas to solve the pain point of long waiting time for high-speed charging. In cities, fast charging stations and household charging piles (480kW) are mainly used. It is understood that overcharged piles are mainly placed in high-speed service areas, and ordinary charging piles are mostly in urban areas (250kW).

Why did you move Kuaichong to the expressway?

This has to involve a problem of "cutting peaks and filling valleys". Take the basic electricity load of a typical residential area as an example. During the off-duty peak hours, whether charging at home or charging at a charging station near the community, the peak electricity consumption will overlap. This ultra-fast charging will cause great load to the power grid in a short time, and the load summit will seriously affect the safety and stability of power supply, so it is necessary to improve the lines and transformers, and the power grid will have to spend extra money to lay new feeders and purchase transformers.

Especially in the urban distribution network, the product of charging station may not be considered at the beginning of design, especially in the distribution network around the old community. Moreover, the construction resistance of distribution network is great, and the expansion of substation is difficult; And put a high-power overcharge station around? The higher the charging power, the higher the peak value, which aggravates the peak-valley gap of the load, and then makes the capacity of the distribution network more tense. Moreover, this charging station does not have the energy storage function of changing power stations, and it cannot "cut peaks and fill valleys" for the power grid, so it will be more idle and wasteful for the power grid.

On the other hand, even if you are overcharged, standing in the city, the models are piled up for charging (one 480kW with two 250kW electric piles), and the power really allocated to your 480kW charging pile may not be enough for this electric pile to run at full load, and it will not be ideal. Overcharging, in the case that the supporting capacity of the power grid is not so plentiful, the gimmick is greater than the actual use.

About this problem, it can only be that most subsequent overcharge stations need to be equipped with energy storage systems, and the charging and discharging speed of batteries is getting faster and faster, and the technology is becoming more and more mature. As long as the overcharge station is equipped with several times the capacity of the vehicle battery pack, it can be used in theory without bringing pressure to the power grid. At this time, overcharging can solve the problems of slow charging and mileage anxiety of pure trams.

Compared with charging, the charging experience is more comfortable, at least for now.

There is no innovation in replenishing energy, and the owner's car experience will be discounted?

Li, who has been working hard in the field of program promotion before, transferred to the field of pure electricity this year, and has no advantage in the new track, which can also be said to be starting from scratch. Moreover, it seems impossible to use high-end liquid-cooled over-filled piles in the scheme, but in fact there are many hidden problems, including the above, how to allocate the ratio of over-filled piles to fast-filled piles reasonably, and the over-filled station cannot enter the urban area.

From this point of view, in the pure electricity market, Ideal has some shortcomings in selectivity and experience compared with Weilai's two modes of energy supplement. Moreover, the coverage area of its charging station is unknown, but in fact, Li began to lay the charging station before the planning was announced, which should have started in the fourth quarter of last year, so there is no need to worry about the ideal coverage of the charging station.

As a prospective car owner, do you need to worry?

Judging from the exposure information, the first pure tram is an MPV product, which should still be the main home market, with a large size and Kirin battery of contemporary Amperex Technology Co., Ltd. In the same market, Kykrypton 009 also adopts the Kirin battery of Contemporary Ampere Technology Co., Ltd., which is a 140 degree battery pack scheme with a comprehensive cruising range of 800km.

If it is assumed that the first pure electric MPV in Li Can is also equipped with a Kirin battery pack of 140 degree, its cruising range will theoretically fluctuate at the level of 800km, and the charging efficiency will be very high. In the words of contemporary Amperex Technology Co., Ltd., it is called "10 minute charging to 80%", but to achieve this effect, the whole vehicle platform and electric piles need to cooperate. Even using household charging piles or third-party charging piles is enough, and the cruising range of 800km level will not have too high charging frequency.

Therefore, in the choice of vehicle models, the ideal will "foster strengths and avoid weaknesses".
