If you are asked what is the reason why you don't buy new energy vehicles, many people's answer may be that the charging speed is too slow.
Because of the current range anxiety problem, the core is the charging speed problem, at present, many new cars have reached more than 600 kilometers, or even reached 1000 kilometers, battery life is no longer the biggest problem, but the charging speed is slow, it is still difficult to solve the problem of electric vehicles.
Recently, Huawei announced that it will launch a new liquid supercharge, "Electric vehicles will be fully high-voltage, and the charging experience of 1 km in 1 second, 200 km in 5 minutes, and refueling has become a reality." On February 27, Hou Jinlong, Director of Huawei Board of Directors and President of Huawei Digital Power, said at the 2024 Huawei China Digital Power Partner Conference, "It is expected that the number of electric vehicles will increase tenfold in the next ten years, which will promote the rapid and substantial growth of charging volume and demand for charging piles." ”
With a maximum output power of 600kW and a maximum current of 600A, this brand-new fully liquid-cooled supercharging station can achieve a charging speed of one kilometer per second, infinitely close to the charging experience like refueling. At present, the 200-1000V charging range of Huawei's fully liquid-cooled supercharging is compatible with all models, including passenger cars such as Wenjie, Tesla, Xpeng, and Li, as well as commercial vehicles such as Cargo Lala.
Speaking of which, there will definitely be smart doubts, such a large power grid can't withstand it, so I want to ask, if the power grid can't withstand it, why did Huawei spend so much manpower, material and financial resources to develop it? Others won't do research before R&D and won't consider feasibility?
I say responsibly that the current new energy vehicle charging power bottleneck is not because the power grid can not withstand it, but because the battery capacity is limited.
Grid load problem, the current solutions are many, such as virtual power grid, such as energy storage station, believe it or not, if the solid-state battery comes out, can withstand 800 kilowatts of high-power fast charging, then tomorrow car companies will announce the follow-up launch of the corresponding ultra-high power charging pile, the power grid will also launch the corresponding scheme, the problem now is that the carrying capacity of the battery is limited.
Huawei's innovative all-liquid-cooled supercharging technology has passed highly reliable design and high-quality verification, with a service life of more than 15 years.
He Bo, Vice President of Huawei Digital Power Technology, summarized that there will be four major trends in the future:
Trend 1: The demand for supercharging has penetrated from a single scenario to multiple scenarios to achieve three major benefits.
After users get used to overcharging, they are no longer willing to use slow charging, so in the future, supercharging stations will enter buses, heavy trucks, logistics, parks, and even counties from high-speed, urban and other scenarios.
Trend 2: Build a safe and reliable charging network.
Huawei is also working with battery manufacturers to develop battery safety technologies, and the risk of charging safety will be lower and lower in the future.
Trend 3: Integrate optical storage and charging to build a grid-friendly charging network.
The charging capacity in 2023 is 03 trillion kWh, with an estimated charging capacity of 1 in 20282 trillion kWh, with a charging capacity of 2 in 2035700 million kWh. In response to the above-mentioned problem of a large burden on the power grid, He Bo said that photovoltaic storage and charging will be a high-quality solution, and the fixed cost of photovoltaic power generation in Huawei's campus is only two cents, and it is sold to the grid for 4 cents, but if it is sold through charging piles, it may be sold for more than one yuan.
Trend 4: The integration of vehicles, piles, and networks has developed, and the charging network has entered a comprehensive intelligence.
In the future, car owners will not only buy electricity from the grid to charge, but also buy electricity at a low price, and feed electricity to the grid when selling electricity, which will give birth to more business models and will further drive the development of electric vehicles and charging networks.
So, when will Huawei's supercharging pile be built? Huawei said that it will take the lead in deploying more than 100,000 Huawei fully liquid-cooled ultra-fast charging piles in more than 340 cities and major highways across the country in 2024, hoping to achieve high-quality charging where there are roads.
At present, it takes 3-5 minutes to change the battery, if you encounter the queuing time, it is not easy to say, the speed of the battery replacement is also related to the battery reserve of the battery swap station, once the fully charged battery is used up, the time of battery replacement will depend on the time of battery charging, in addition, the battery swap station has high construction costs, and the problem that only one car can be replaced at the same time, therefore, in the face of the menacing Huawei supercharge, the advantages of the battery swap mode are gradually lost.
