When everyone thinks that Huawei is still focusing on the automotive industry, it has actually quietly entered the charging pile industry. We are talking about Huawei’s “liquid-cooled supercharging” charging piles that have become a hit in the industry this year. By the end of 2024, it plans to deploy them on highways in many cities across the country and invest in the construction of more than 100,000 new charging piles.
Even for the new energy vehicle circle, "liquid-cooled overcharging" is a new concept. So what is "liquid cooling overcharging"?
As we all know, for new energy car owners, the biggest worry besides mileage is charging. The charging time of AC charging pile is as short as 6 hours and as long as 8 hours. DC charging piles are faster than current charging, but it will take at least half an hour to charge the car from 20% to 80%.
Liquid-cooled supercharging has a special liquid circulation channel between the cable and the charging gun. Liquid coolant for heat dissipation is added to the channel, and the coolant is circulated through a power pump, thereby dissipating the heat generated during the charging process. come out. To put it bluntly, the charging head contains two tubes, one tube goes in and one tube comes out. During use, the liquid in it continuously dissipates heat to the charging pile, so its charging efficiency is the same as The charging efficiency of traditional electric piles has greatly widened the gap, and can even charge more than one kilometer per second.
In addition, the "liquid-cooled supercharge" charging pile has very low operating noise and high safety. Because of the liquid cooling and fully enclosed design, the entire charging pile can effectively isolate flammable and explosive gases and has a high level of protection. Its charging cable is also very slim. The current national standard 250A charging gun cable generally has a wire diameter of 80mm², which is bulky and difficult to bend and store. The cable diameter of the 500A liquid-cooled charging gun is only 35mm², and the charging gun is also lighter than a conventional charging gun.
Finally, the service life of "liquid-cooled supercharging" charging piles is twice that of traditional electric piles, which is undoubtedly more cost-effective for electric pile operators. According to relevant statistics, by 2026, models that require fast charging of more than 480 kilowatts will account for half of that year’s sales. In order to cope with this trend, more and more car manufacturers and operators may begin to lay out this supercharging industry in the future.
As the global market share of new energy vehicles gradually expands, charging piles will be a key link for new energy vehicles to completely replace fuel vehicles. Charging piles are as important to new energy vehicles as gas stations are to fuel vehicles. Once the industry leads to explosive growth, it is bound to create a new main market.
