Since 2025, the energy replenishment technology for new energy vehicles has entered a new stage of development. From BYD's launch of a megawatt level flash charging platform, to CATL's continued promotion of the supercharging ecosystem layout, and to Huawei's proposal to enter the megawatt era of charging networks, the industry is forming an increasingly clear consensus: the competition for supercharging in the future is not only about power, but also about thermal management capabilities. Supercharging networks are accelerating their evolution towards megawatt level, high reliability, and intelligence, and liquid cooling technology is increasingly seen as an important support for high-power charging infrastructure by more and more enterprises.

In this industry context, Xi'an Tiantai Electronics Co., Ltd., which has long focused on the field of new energy thermal management, is continuously conducting product research and development and technological optimization around ultra charging liquid cooling systems, using thermal management capabilities to serve the construction of new energy charging infrastructure.

The development of supercharging is changing the role of thermal management

In the past few years, the new energy vehicle industry has been pursuing "faster charging". 350kW, 480kW, and 600kW liquid cooled supercharging are gradually becoming popular, and with the emergence of megawatt level supercharging platforms, "charging for a few minutes and recharging for hundreds of kilometers" is moving from concept to reality. But the faster the charging speed, the greater the current and the more concentrated the heat. Industry insiders generally believe that as the charging power continues to increase, the real challenge facing the device is not whether it can output greater power, but whether it can maintain stable operation under sustained high load conditions. This is also why more and more supercharging devices are adopting liquid cooling solutions.

Liquid cooling not only effectively reduces the operating temperature of charging guns, cables, and power modules, but also enhances the continuous output capability of the system, reduces derating caused by temperature rise, and creates a more stable operating environment for high-power charging.

Liquid cooled supercharging is becoming a common direction for industry development

If we go back three to five years, liquid cooling supercharging was still a "new thing" in the industry, but today, liquid cooling has become an important technological route for leading companies to layout supercharging networks. When BYD released its megawatt flash charging platform, it also simultaneously launched a liquid cooled charging system; Huawei also regards liquid cooling technology as an important component of high-power charging networks in the latest charging network trends, and proposes that the future electrification of commercial vehicles and heavy trucks will further promote the development of megawatt level liquid cooling charging. This indicates that liquid cooling is no longer just a technological choice for a single enterprise, but is becoming a common direction for industry development. The reason is also simple. Air cooling can solve the problems of ordinary charging equipment, but in the face of continuously increasing power density, relying solely on air heat exchange is becoming increasingly difficult to meet long-term stable operation needs. Liquid cooling enables equipment to maintain a stable state even under complex conditions such as high temperature, high current, and long-term operation through more efficient heat transfer capability. For operators, this means higher equipment availability; For users, it means a more stable high-power charging experience.

In the era of supercharging, the competition is about system capabilities

Many people believe that the most important aspect of supercharging equipment is power, but in fact, when the industry enters the megawatt era, power is no longer the only indicator. What truly determines the value of equipment is whether the entire system can operate stably for a long time, from liquid cooling of charging guns and cables, to heat dissipation of power modules, to liquid cooling units, intelligent temperature control, and heat exchange systems. Each link will affect the final operating effect. Therefore, the competition of supercharging devices has gradually evolved from single device competition to system capability competition. As an important participant in the field of new energy thermal management, Xi'an Tiantai Electronics has continuously carried out research and development work around liquid cooling and heat management systems in recent years, forming a product system covering liquid cooling units, heat exchange systems, intelligent temperature control, etc., and continuously optimizing products in combination with new energy charging scenarios. The company focuses more on the operational performance of equipment under real working conditions, rather than short-term test data in the laboratory. Because what truly determines the value of a device is whether the system can still maintain stability after thousands of hours of continuous operation.

From charging stations to energy storage systems, thermal management capabilities are expanding

It is worth noting that the application of liquid cooling and heating management is no longer limited to supercharging equipment. With the continuous development of integrated storage and charging modes such as light storage and charging, charging stations have begun to integrate multiple systems such as energy storage and power electronics. The overlapping thermal management requirements between different devices also pose higher demands on the overall thermal management scheme. This means that in the future, thermal management will no longer be about single device heat dissipation, but rather temperature management of the entire energy system. Xi'an Tiantai Electronics is also continuously improving its thermal management system solutions around this trend, enhancing the adaptability of its products in multi scenario and multi system collaboration.

The new energy vehicle industry has entered the "supercharging era", which not only brings about an improvement in charging speed, but also promotes the upgrading of the entire industry chain technology system. Power can be continuously broken through, but for equipment to truly achieve long-term, efficient, and stable operation, more mature thermal management technology is indispensable. Liquid cooling is evolving from a heat dissipation method to an important underlying capability supporting high-power charging infrastructure. In the future, with the continuous implementation of applications such as megawatt supercharging, heavy-duty truck energy replenishment, and storage and charging integration, the importance of thermal management will further increase. Xi'an Tiantai Electronics stated that it will continue to deepen its cultivation in the field of ultra liquid thermal management, adhere to the guidance of technology research and development and scenario application, continuously improve product reliability and system integration capabilities, and provide more stable and efficient thermal management support for the construction of new energy replenishment infrastructure. Today, as supercharging moves towards the megawatt era, what truly determines equipment competitiveness is not just how much power is output, but also whether each degree of heat can be managed well.
