For a long time, the problem of long charging time of charging piles has caused trouble to owners of electric vehicles and seriously affected the user experience. The emergence of liquid-cooled supercharging technology has greatly improved the charging speed and alleviated charging anxiety.
Liquid-cooled supercharging technology solves the problem that heat dissipation and high-power charging cannot be combined, and accelerates the charging speed. During the charging process, the high-power current will generate a lot of heat, which will cause damage to the battery and the charging pile if the heat is not dissipated in time. Conventional charging piles use air-cooled modules for heat dissipation, which can take away limited heat. Under such conditions, it is difficult to increase the charging current. Liquid cooling has a stronger heat dissipation capacity than air cooling, and the liquid-cooled supercharging technology adds a liquid-cooled channel between the cable and the charging gun, in which the coolant or oil-cooled insulating oil is driven by the power pump to complete the cycle, taking away more heat, which means that the power of the charging pile can be further improved, theoretically only need to charge for 5 minutes, and the cruising range can exceed 300 kilometers, bidding farewell to the problem of slow charging in the past.

However, although liquid-cooled supercharging technology can effectively alleviate charging anxiety, there are technical barriers to the cable components connecting the liquid-cooled gun and the charging pile, and the production cost is also high, so it has not been deployed on a large scale. Cables need to use materials with higher strength to meet the requirements of high temperature resistance, low temperature resistance, cold resistance, corrosion resistance, and blasting resistance, which is technically difficult and costly. In addition, the cost of liquid-cooled charging cables accounts for about 20% of the charging pile, which is the second highest cost per component, after the charging module, and the material needs to be improved to reduce costs.
Therefore, it is very important to develop low-cost cable materials and liquid-cooled charging cables, which are one of the future development ideas. In addition, expanding the scale of mass production to reduce production costs is also one of the ways to solve the cost problem. The good news is that due to the continuous improvement of the penetration rate of new energy vehicles, domestic car companies and pile enterprises will accelerate the layout of liquid-cooled charging piles in the future. When the scale of the industry expands, the average cost of mass-produced liquid-cooled charging piles will decrease. At that time, liquid-cooled supercharging piles will be popularized, benefiting more tram owners.
