Huawei plans to deploy 100,000 super-fast charging piles in 2024 to create an efficient electricity consumption experience of "one kilometer per second" and "ten kilometers per kilowatt-hour" for car companies.
On April 24, Huawei held a new product launch conference for smart charging networks. At the conference, Hou Jinlong, President of Huawei Digital Power, announced the "One Body, Three Sides" electrification strategy, which aims to accelerate the process of vehicle electrification through high-quality collaborative development of smart electric vehicles and smart charging networks.
To this end, Huawei, together with car companies, charging operators, and industry partners, has established the Supercharging Alliance to build a comprehensive supercharging network for users and promote the rapid and high-quality development of the new energy vehicle and charging network industries.
In addition to Huawei, the car companies that have joined the alliance are: Nezha, Xiaopeng, BYD, Jihu, AVATAR, Cialis, Jiangqi, Great Wall, Ideal, GAC, and Chery.
Ecological construction
At present, there are mainly the following problems in charging piles, which are the pain points of car owners in daily use:
1. The number of charging piles is insufficient, and with the increase in sales of new energy vehicles (2023), the construction speed of charging piles is obviously unable to keep up, resulting in a rapid increase in the waiting time of new energy vehicle owners
2. The charging speed is slow, and a large part of the charging piles do not have a high-voltage fast charging function, which leads to the extension of the charging time
3. Compatibility problems, different brands of electric vehicle charging standards are different, resulting in some car owners unable to use normally even if they find a charging pile
In addition, uneven distribution and inadequate operation and maintenance are also serious problems for charging piles.
To solve these problems, it is necessary to build an alliance, the alliance collects more data, and uniformly deploys charging piles, which areas need to deploy more, and which areas need relatively less.
Enterprises that join the alliance use a common charging standard, which solves the compatibility problem, and there is no phenomenon that cannot be charged due to different standards.
It's also easier to operate, maintain, and upgrade.
The necessity of creating high-voltage fast charging
New energy vehicles have two major shortcomings, battery life and safety, which is basically a problem that all car owners are worried about, and it is also a problem that manufacturers urgently need to solve.
To solve the problem of battery life, we need to start from two aspects, one is the battery, and the other is charging.
At present, most of the power batteries are lithium iron phosphate batteries and ternary lithium batteries, lithium iron phosphate batteries are relatively safe, but the energy density is between 150Wh/kg and 300Wh/kg, and the energy density of ternary lithium batteries is relatively large, and the highest is only 300Wh/kg.
In winter, the battery life is discounted, and even as low as 1/3 is common, to solve the lack of battery life, it is necessary to use a new type of battery, and the current mainstream technology direction is solid-state batteries.
But it is too difficult to operate in practice, electrolyte, electrode, charge and discharge, each of which is a big mountain, and it is impossible to completely overcome it in a short period of time.
At the same time, it cannot be popularized in a short period of time because of the high cost.
Therefore, it is particularly important to complete the charging quickly. At present, public charging piles are mainly based on slow charging, and the charging time is generally 1 hour or more.
In order to solve the charging problem and accelerate the popularization of new energy vehicles, more and more companies have launched high-voltage fast charging platforms and high-rate batteries.
High-voltage fast charging will become the standard configuration of electric vehicles in the future, and the development of high-voltage architecture at the vehicle end has become a trend.
The newly released Xiaomi SU7, Wenjie, Zhijie S7, Leapmotor C16 and other models are equipped with 800V high-voltage fast charging, and car electrification, intelligence, and fast charging are rapidly popularizing. Chairman Xinwangda bluntly said: In the future, models of more than 100,000 yuan may support 800V ultra-fast charging technology.
Huawei will deploy 100,000 high-voltage fast chargers this year
Hou Jinlong said: In 2024, Huawei will work with customers and partners to deploy more than 100,000 ultra-fast charging piles.
These charging piles will use Huawei's all-liquid-cooled supercharging solution, with a 600/720 kW host and a single gun with a maximum power of 600 kW and a maximum current of 600 A, which can be charged to 1 km in one second.
At the same time, in terms of model compatibility, Huawei has also done a lot of docking tests, proving that the all-liquid-cooled supercharging solution can be adapted to different brands of models, with a one-time charging success rate of more than 99%.
At the same time, Huawei has also deployed technologies such as ultra-high-speed motors and thermal management, launched a variety of high-voltage and high-efficiency electric drive systems, and will work with car companies and leading battery manufacturers to jointly define supercharging vehicles.
Improvements have also been made in equipment maintenance, which is more convenient for maintenance, and the service life has reached 15 years.
At present, Huawei's supercharging has covered more than 30 provinces, municipalities and autonomous regions, including Beijing, Shanghai, Guangdong, Chongqing, and Sichuan, and has adapted to extreme cold, heat, and high-altitude environments.
At the same time, Huawei has also sunk into the county and township markets to achieve "county and county supercharging stations, and township supercharging piles".
For Huawei's technology, netizens are not worried, but they are worried about 100,000 super charging piles a year, can the funds and progress keep up?
The cost of an ultracharging pile is hundreds of thousands, 100,000, and the investment has reached tens of billions, which is not small, and it is still very difficult to rely on Huawei alone, after all, Huawei also has to engage in AI chips, Pangu large models, and pure-blooded Hongmeng, Mate 70, cloud computing and so on in the second half of the year.
If you can introduce PetroChina, Sinopec, and State Grid, I think the progress of super charging piles will be faster, and the scale will be larger.
At present, there are 107,600 gas stations in the country, and if all of them are replaced with charging piles, more than 2 million will be needed.
What's even more worrying is that if 2 million charging piles are really built, can the power grid withstand it? This is why many places are rapidly developing energy storage and virtual power grids.
China's new energy vehicles are in full swing, with production and sales of new energy vehicles in China reaching 9.587 million and 9.495 million units in 2023, an increase of 35.8% and 37.9% year-on-year, respectively, with annual sales of nearly 10 million.
According to the current growth rate, the sales of new energy vehicles in mainland China will exceed 10 million units in 2024, far exceeding developed countries such as Europe and the United States. But at the same time, these huge electric vehicles also need more supporting facilities.
Charging piles are undoubtedly the most critical and important, and at this time, Huawei has launched super charging piles, which are not only in line with the national conditions but also conform to the people's will, and will be supported by more car companies.
If it can get the support of central enterprises such as SAIC, Dongfeng, FAW, and Changan, Huawei will basically have no rivals in the field of charging piles, and it will be easier to do a good job in the ecosystem.
Only by allowing enterprises with capable and technical strength to do charging piles can they be charged for one kilometer in one second and fully charged with a cup of coffee, so that consumers can rest assured and boldly buy new energy vehicles.
The better the development of new energy vehicles in China, the better the use effect, in order to attract more overseas people to buy Chinese new energy vehicles, and the supporting charging facilities, batteries, and motors will also be more favored.
Who doesn't love such a commodity, such a commodity is of good quality, low price, and advanced technology? Even if the United States wants to blockade it and use bad money to drive out good money, it must weigh how many pounds and taels it has.
I'm a science and technology master, if you like it, give it a like!
