Another black technology that is far ahead and subverts the new energy market

Author：AliceDate：2024-1-12

        During festivals and holidays, highways experience the most intensive traffic of self-driving people,  and whether they can grab charging piles has become a matter of great concern to car enthusiasts. Te Laidian quietly launched a new technology that is far ahead of the curve: liquid-cooled supercharging technology that can charge a vehicle for 300 kilometers in 5 minutes, which shows how marketable it is.

         Whether it is in a highway company or a city business district, Te Laidian has long been able to "charge the car as soon as it comes, charge and go". It is compatible with all car models and can be charged as soon as the car arrives: the one-time charging success rate is as high as 99%, and the 200-1000V charging range matches all car models, including various passenger cars and commercial vehicles such as Lalamove. In high-altitude areas, it can still provide new energy car owners with a charging-like experience. “A cup of coffee and a full battery to start” is enough to describe the advancement of this technology.

1. How far ahead is 600kW?

         Generally speaking, the greater the power, the faster the charging. A charging power of 600kW means "600 degrees of charging in one hour." Then it only takes 10 minutes to charge 100 kilowatt hours of electricity, and the charging efficiency is greatly improved.

         By comparison, the general power of supercharging piles on the market is still around 300kW. The peak power of Tesla V3 supercharging pile can reach 250kW, charging for 15 minutes to run 250 kilometers; the peak power of Porsche 800V high-voltage supercharging has also reached 270kW. , it takes 30 minutes to charge from 5% to 80%.

         While competitors are still producing 800V voltage and 360kW charging power, Te Laidian has already achieved 600kW or even 720Kw. First of all, we need to understand what the concept of 600kW overcharging is. Ordinary home slow charging is generally 7kW, and the speed of special power overcharging is nearly a hundred times that of home slow charging. The power of State Grid charging piles is generally 40~60KW, and 600KW is more than ten times that.

Second, what is "liquid cooling overcharging"?

         It is to set up 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 to take out the heat generated during the charging process.

         The power part of the system uses liquid cooling for heat dissipation, and there is no air exchange with the external environment, so it can achieve an IP65 design. At the same time, the system uses a large air volume fan to dissipate heat with low noise and high environmental friendliness.

         Why is it said that Telaidian’s super charging pile represents the highest technical level in the industry? What are the harsh conditions required to manufacture such a high-power supercharger?

         Today we will briefly talk about it from the perspective of consumers, so that even if you are a novice who has never studied physics, you can fully understand it.

         Under ideal conditions, the calculation is based on charging time (h) = battery capacity (kWh) / charging power (kW), which means that a new energy vehicle with a battery capacity of 50kWh can charge 600 kWh in one hour, with a power of 600kW. It only takes 5 minutes to complete the energy replenishment. Generally speaking, 14-18 kilowatt hours of electricity can last 100KM, which means that after 5 minutes of charging, the battery can last 300+KM.

         Of course, the premise is that your electric car is equipped with a kilovolt high-voltage platform.

3. How to achieve ultra-fast charging with liquid-cooled overcharging?

         Liquid-cooled supercharging charging piles have the characteristics of high charging efficiency, low heat generation, high safety, and low noise.

         First, the current is larger and the gun wire is lighter. The innovative liquid-cooled high-power module can intelligently adjust the flow rate, fan, and water pump speed to meet the heat dissipation of the 600A cable. The weight of the liquid-cooled gun cable is less than half of the traditional charging gun cable.

         Secondly, the charging noise is small and the protection level is high. It adopts a silent gear pump, a special cavity line design, and the noise is less than 60db. It adopts a partitioned design to withstand a variety of extreme weather conditions, and the safety protection level is as high as IP55.

         Finally, there is intelligent interaction, plug and charge. Liquid cooling equipment has cloud monitoring and remote upgrade functions. Just perform "car authentication" on the Telaidian APP to automatically identify the car model, plug in the gun and charge.

4. What is the future trend of liquid cooling overcharging?

         Looking back at the entire development process of fast charging/overcharging, Te Laidian has achieved the initial effect of overcharging as early as 2018. After the accumulation and maturity of industry technology, it has achieved fast charging and overcharging - 5 minutes of charging, 300 kilometers of battery life .

         The penetration rate of high-power liquid-cooled supercharging piles in my country is still low. This is not only because the cost of liquid-cooled charging guns is relatively high, but more importantly, whether the battery performance of electric vehicles can carry high-power fast charging, and power distribution. Whether the network can support simultaneous high-power charging of large-scale electric vehicles.

         Here, we have to mention TeLaidian’s group charging technology. Its latest group charging 4.0 adopts two emerging technologies: “power cascading” and “power pool modular expansion”, which can realize intelligent scheduling according to the charging power of the vehicle. And orderly charging can effectively meet the charging needs of different vehicles. The liquid-cooled supercharger can charge in 5 minutes at the fastest and has a range of 300 kilometers, making the entire charging efficiency 2% better than the industry.

        Group charging technology and liquid-cooled supercharging are a core technology of Te Laidian. It has changed the speed and efficiency of electric vehicle charging, and has also provided important support for the popularization and development of electric vehicles.
