For pure electric vehicles, people have always had endurance anxiety, but with the advancement of technology, the battery life is increasing. There have been many companies that have released a “big satellite” of 1,000 kilometers, such as the sauce, Guangqi Ean, SAD, and Tesla. Indeed, if you can run 1000 kilometers, you don’t have to worry about life, let’s take a look at whether these cars are reliable, is the technical breakthrough or a head?
Available Solid State Battery
The first sedan ET7 released on the next day, the price is 448,000 -52.6 before subsidies 10,000 yuan, it is expected to be delivered in the quarter of 2022. But this is a normal version, and it is equipped with the latest 150KWH battery pack, and the official website can reach 1000 kilometers, but the traffic will wait until 2022 fourth quarter.
It is not announced where the battery supply is from, but the industry is generally considered to be Ningde era, and there is also a rumor that it is to develop. It is a solid state battery technology to achieve a super high energy density of 360WH / kg.
Theoretical solid state battery energy density is more than 700Wh / kg, and is more security compared to liquid batteries, when damaged, it is not burned or produced. Explosion, the technology is indeed more advanced.
However, the solid-state battery, which is currently mentioned, is “in situ curing” battery, which uses solid-liquid electrolyte technology, in fact “Semi-solid batteries” is a transition program that is currently no breakthrough in the world. Therefore, it takes two years to be listed two years later, because there is no supplier for the time being, so I can only look forward to it.
Guangqi Ean uses graphel batteries
Guangqi Egyan aspect, the Future of its Aion LX, Aion VThe change model will be equipped with a stone-based battery and a long-lasting silicon negative electrode battery, and NEDC has ended 1000 kilometers, and it can achieve 80% of 80%.
However, the statement of GAC has been questioned by authoritative experts. In fact, from the official statement of Guangzhou Automobile, the proposed graphene supercharged battery and long-range silicon negative battery are two different technologies, which solve the “slow charging speed” and “battery short”. Different pain points in power battery applications.
Experts questioned that the continuation of the long, the fast charging and low cost, and the current point of view is true. However, Guangzhou Automobile said that there is a conditional realization, and when it is refuted, “laboratory and business promotion cannot be mixed into a talk.”
Guangqi’s statement is actually very expensive, and the means of improving charging efficiency is to increase charging power, which can be achieved by increasing charging voltage and current, most of the current products can If you are charged to 80%, if the vapor is doubled while the charging current and the voltage are doubled, then 8 minutes charging to 80% is not to be realized, but it is necessary to improve the capacity of the battery.
Therefore, for this “satellite” of Guangqi Ean, consumers are still happy. According to the timetable given by Guangzhou Automobile, the graphene super fast charging battery is expected to be mass production in September, the first mounting model is GAC ENA AION V, and the endless mileage is 500-600km.
The new battery of the 1000km endless silicon will also produce in the fourth quarter of this year, the first mounting model is GAC ENA AION LX. It is equipped with a safety battery through a shooting experiment, will be taken first on the AION Y in March this year. 
Shangqi wisdom has adopted a silicon-donate battery
As a newly created brand, the feeling of superficial wisdom has given people still is quite pragmatic. When I officially debuted on January 13, I sent it.There are two new cars, which are cars and an SUV. It is expected that on the April 2021 Shanghai Auto Show, there will be 3-4 cars unveiled, and open the first mass production vehicle pre-sale. By the fourth quarter of 2021, the mass production car will be officially sold, and the speed is very fast.
Battery, TAK has determined that the use of “silicon-doned lithium battery cell battery” technology will have 200,000 kilometers 0 attenuation, and finally NEDC life mileage or will break through 1000km, the supplier is basically determined to be the Ningde era, the new car will equip the 11kW powerful wireless charging, combined with the automatic autofed parking function “No need to operate, no sense of complement”. 
From SAV, Ali and Pudong New Area, jointly investment, holding 10 billion huge money, ShangAqi wisdom can be said to be a “rich second generation”, I don’t currently see the problem of lack of money.
From the current new car, the appearance interior design does make people look bright, 39 inch huge display, can also achieve score or drop, and claim At the end of 2021, the “full scene, the most continuous, zero-tube” point-to-point automatic driving, 2022, in the country, the main cities in China pushed autonomous valet parking.
Tesla uses cobalt battery
Currently, the sales of electric vehicles, Tesla is on the issue of 1000 kilometers, relatively Compare low-key. In fact, Tesla new generation of electric sports car Roadster, known as the battery life reached 1000 kilometers.
This car is equipped with a battery pack of 200kw / h to drive the motor, the maximum battery life exceeds 998km, 0-96km / h acceleration time is only 1.9 seconds. It is scheduled to be delivered in 2020, but “jump”, it may be delayed until 2022.
There is nothing special on the battery, which is “cobalt battery”, 即 Tesla Self-research ” ten thousandMile “battery, as the name suggests, this battery life is expected to reach 1 million miles (about 1.61 million kilometers), and the energy density reaches 400 wh / kg. I believe that as long as Tesla’s battery problem is solved, the car is also listed, And it will also be promoted to more models, but there is only no breakthroughs.
Summary 
Point can be determined: First, battery core technology has no quality breakthrough; second, the manufacturer said 1000 kilometers is setting conditions. That is to say, even if it is true, it is not necessarily the best program, the car Affiliate is also the high price, can’t fly into the home of the usual people.
So, everyone’s 1000 kilometers more is to prove their strength, improve the brand image, and the real amount of models. Still five or six hundred kilometers. With the improvement of infrastructure, this continuous number of large number of applications is enough. And the pure electric car next core pain will be the control experience and safety.
