Shanghai Auto Show just announced that the ideal pure electric MPV plus overcharge scheme has something to watch?

Six years after the establishment of Ideal, it is finally going to enter pure electricity, which should be done this year.

it is not beneficial for the development planning after the brand to rely on a single driving form of extended range, which will only make the market smaller and smaller. LI's long-planned pure electric plan should be revealed at the Shanghai Auto Show in mid-April. At present, the information exposed is that a scheme for charging pure electric vehicles will be announced.

As for LI's pure electricity scheme, it's almost announced now: the first pure electricity may be a pure electric MPV； code-named "W1" just like the online exposure; Contemporary Amperex Technology Co., Limited interacted with the ideal on the Weibo before, and also admitted that the ideal Kirin battery for 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 make pure electricity ideally, which meets the needs of mass consumption, and 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". Now there are several mainstream solutions, such as ordinary charging piles, high-power overcharged piles and power replacement.

according to the actual situation, the ideal can be brought out now, and it should only be the combination of ordinary charging piles and high-power super-charged piles. The question that consumers care about should not be how many advanced technologies are covered, but whether this overcharge can be used easily. High-power overcharge can solve the pain point?

The construction information now exposed is Chehejia (Dongguan) Energy Service Co., Ltd., a wholly-owned subsidiary of LI. The project starts on November 28th, 222 and will be completed on March 31st. The picture shows that the overcharging station has four charging piles, which are expected to be one 48kW overcharging pile and three 25kW charging piles.

Let's think about a question first. If charging piles and super-charged piles are easy to use and can perfectly solve the problem of energy replenishment, why is Weilai still spending energy on self-research and burning money to change power stations with coverage? In fact, by thinking about this problem, we can analyze that if we have the ability, ultra-fast charging is definitely not the optimal solution of the energy replenishment 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, and the whole experience process is very close to the experience of adding a tank of oil to a fuel car.

is the technical content of over-filled piles high?

At present, the technology of fast filling is not uncommon, including Weilai, Tucki, Tesla, etc., all choose this scheme of fast filling piles. 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 keep the whole process, and the charging capacity of the battery should be considered, so the slogan "X minutes, XXX kilometers of charging" was used instead of the propaganda slogan "X minutes, fully charged".

then, it is unknown whether the ideal fast-filling pile is cooled by liquid or water, and the specific details are not said. However, the high probability should be the liquid-cooled charging cable. Liquid-cooled cables are superior to water-cooled cables in terms of heat dissipation capacity and external environmental impact. Tesla's V3 quick-filling pile uses liquid cooling module, which can also be used under the extreme cold test on the plateau. Secondly, during the Beijing Winter Olympics, the fast-charging piles in some charging stations also used liquid-cooled modules.

Then, the ideal plan is to invest 1 billion yuan to build 3, overcharging stations by 225, and these overcharging stations are expected to be built in the expressway service area to solve the pain point of long waiting time for high-speed charging. In cities, fast charging stations and household charging piles are mainly used (48kW). It is understood that over-filled piles are mainly placed in high-speed service areas, and ordinary charging piles are mostly in the city (25kW).

why did you move the express charge to the expressway?

here we have to deal with a matter of "cutting off the peak and filling the valley". Take the basic electricity load of a typical residential area as an example. During the late rush hour after work, no matter charging at home or nearby charging stations in the residential area, the peak electricity load will overlap. This kind of 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 acquire transformers.

especially in the distribution network in the city, the product of charging station may not have been considered at the beginning of design, especially in the distribution network around the old community. Moreover, the resistance of distribution network construction is great, and the expansion of substation is difficult; And put a high-power overcharge station around it? The charging power is bigger and the peak value is higher, which aggravates the gap between the peak and the valley of the load, and then makes the capacity of the distribution network more tense. Moreover, this charging station does not have the function of storing energy like changing power stations, and it can't "cut the peak and fill the valley" of the power grid, so it will be even more idle waste to the power grid.

then again, even if you are overcharged and standing in the city, when the models are piled up to charge (one 48kW with two 25kW electric piles), the power really allocated to you for the 48kW charging pile may not be enough for this electric pile to run full, 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.

On this issue, 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 stations are equipped with several times the capacity of vehicle battery packs, overcharge can be used in theory and will not bring pressure to the power grid. By this time, overcharge can solve the problems of slow charging and mileage anxiety of pure trams.

compared with recharging, recharging experience is more comfortable at least for now. There is no innovation in replenishing energy, and the car owners' car experience will be discounted?

LI, who has been working hard in the field of program increase before, turned to the field of pure electricity this year, and there is no advantage in the new track. It can also be said that he started 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 rationally allocate the ratio of over-filled piles and fast-filled piles, and the over-filled stations can't enter the urban area.

From this point of view, compared with Weilai's two energy-replenishing modes, Ideal has some shortcomings in selectivity and experience. Moreover, the coverage area of its charging station is unknown, but in fact, LI began to lay charging stations before the announcement of the plan, which should have started in the fourth quarter of last year, so there is no need to worry about the ideal coverage of charging stations.

as a prospective owner, do you need to worry?

according to the exposure information, the first pure tram is an MPV product, which should still be the main product in the home market. It will not be small in size, and it will use Contemporary Amperex Technology Co., Limited's Kirin battery. In the same market, Kykrypton 9 also uses Contemporary Amperex Technology Co., Limited's Kirin battery, which is a 14-degree battery pack scheme with a comprehensive cruising range of 8km.

if it is assumed that the first pure electric MPV in LI can also pack a Kirin battery pack of 14 degrees, its cruising range will theoretically fluctuate at the level of 8km, and the charging efficiency will be very high. In Contemporary Amperex Technology Co., Limited's words, it is called "charging to 8% in 1 minutes", but it needs the cooperation of the whole vehicle platform and electric piles to achieve this effect. Even using home-filled piles or third-party charging piles is enough, and the cruising range of 8km level will not have too high charging frequency.

Therefore, to say that the ideal is good at "fostering strengths and avoiding weaknesses" in vehicle type selection.
