• Establishment of production processes and quality standards

Upon successful completion of the PoC, preparations will be made to enable full-scale production starting in July 2026, leveraging PRETTL Group’s global manufacturing and distribution infrastructure to accelerate market entry. This milestone marks a critical turning point in which TMEVnet’s technology advances beyond the R&D phase into practical industrial mass production.


 

 

At IAA Mobility 2025 in Munich, Germany, TMEVnet showcased its groundbreaking Phase-Change Liquid Evaporation Cooling Technology, a next-generation thermal management solution designed to eliminate the root causes of heat buildup and efficiency loss in ultra-fast EV charging systems.

Unlike conventional liquid-cooling methods, TMEVnet’s phase-change system harnesses the natural process of liquid evaporation to instantly absorb and release heat, maintaining a self-stabilizing thermal equilibrium throughout the charging cycle. The result is a highly efficient and lightweight Flux5 Cable and CryoCooling Connector, capable of sustaining –40 °C core temperatures while delivering megawatt-level power with minimal thermal resistance and zero performance degradation. During the exhibition, numerous European OEMs and CPOs visited the TMEVnet booth,

expressing strong interest in the technology’s scalability and compatibility with the upcoming Megawatt Charging System (MCS) standard.
Through this global debut, TMEVnet reaffirmed its vision — “Thermal Management for Energy” — and set the stage for collaborative projects, pilot deployments, and certification initiatives across Europe’s fast-evolving EV charging ecosystem.

Lightweight for MW class via optimized cross-section & thermal routing

–40 °C cooling core with instantaneous heat absorption

Higher efficiency from reduced temperature rise & losses

Strong interest from EU OEMs & CPOs with on-site meetings

Next steps: EU certification, pilot deployments, co-development

“Under the vision of Thermal Management for Energy, TMEVnet advances as a standard-setting partner for megawatt charging.”

With the growth of the electric vehicle (EV) industry, the evolution of charging infrastructure has emerged as a critical challenge.

TMEVnet is presenting a new paradigm in the ultra-fast charging sector by promoting “innovation beyond existing standards,” going beyond merely supplying hardware.

At CES 2025, TMEVnet received an Innovation Award, gaining recognition in the global market for its technological capabilities.

The company's core competitive edge lies in being the first in the industry to apply a "liquid evaporation–phase change" cooling technology to charging cables.

This technology dramatically resolves the issues of cable weight and heat generation compared to traditional air-cooling methods. It reduces the cable weight to under 10 kg and maintains ultra-low temperatures below -40℃, enhancing both safety and efficiency.

The CryoFlux PowerCable offers over 50% higher efficiency compared to existing technologies and enables megawatt (MW)-level charging.

TM EVNet’s cooling system minimizes power loss by reducing electrical resistance and decreases both the thickness and weight of the cable by more than 50%.

This advancement makes it possible to ultra-fast charge large-capacity battery mobility systems, including heavy-duty EVs, ships, and urban air mobility (UAM).

TM EVNet has been selected for Germany’s Mercedes-Benz startup program “Startup Autobahn,” and is currently conducting a Proof of Concept (PoC) project for megawatt charging in collaboration with Siemens and Mercedes-Benz.

In partnership with strategic investor KingoSpring, the company is enhancing its R&D and pushing for global expansion. It is also in talks to supply its technology to global clients including Tesla and Charging Solutions.

In addition, TMEVnet is expanding the application of its technology to various electrified mobility sectors, such as hydrogen charging stations and electric ships.

The company also prioritizes eco-friendliness, focusing on minimizing energy loss and extending battery life. Its cooling technology prevents overheating during charging, ensuring both safety and efficiency.

This year, TMEVnet was selected for the Deep-Tech TIPS program by the Ministry of SMEs and Startups, receiving up to 1.5 billion KRW in R&D funding.

By going beyond simple charging cable manufacturing, TM EVNet is delivering on the three key values of charging speed, safety, and eco-friendliness—earning attention as an innovator in EV charging infrastructure across Europe, the U.S., and Asia.

 

Cheonan City announced on the 12th that it has finalized the selection of the third cohort of “Cheonan Future Unicorn C-STAR,” which is expected to grow into a key player in the K-Startup hub. The city is promoting the Cheonan Future Unicorn C-STAR development project, which discovers and selects promising startups in collaboration with five local startup support organizations and provides tailored support. The 14 companies selected in the previous two cohorts last year achieved significant results, such as listing on KOSDAQ, by leading the local startup ecosystem with the city’s customized support. For the third cohort, 24 startups based on advanced technologies applied, and after evaluations by more than 10 startup support organizations and private investment institutions, 8 companies were finally selected. The city reaffirmed that the startup ecosystem in the Cheonan region has been further strengthened, as startups with excellent technological competitiveness and high growth potential in a short period of time applied for the program.

The 8 companies selected for the third cohort are: ▲G&T ▲Vision Innovation ▲AD System ▲Mithril ▲HUNIQ ▲TMEVnet ▲Rowane ▲DIGO Labs.

TMEVnet is a company that has developed an innovative ultra-fast charging system based on advanced thermal management technology, and is currently collaborating not only with domestic but also globally renowned electric vehicle manufacturers.

Kim Seok-pil, Acting Mayor of Cheonan, stated, “Cheonan offers an optimal environment for promising startups to grow, thanks to its geopolitical advantages, startup infrastructure, and expanding networks,” and added, “We will continue to provide unwavering support and encouragement so that the companies selected this time can establish themselves as key players in regional growth.”

TMEVNET, a startup developing next-generation ultra-fast EV charging solutions, has been awarded a CES 2025 Innovation Award in the Vehicle Tech & Advanced Mobility category.

The CES Innovation Awards honor companies shaping the future of the global tech industry with cutting-edge technology and groundbreaking products. TMEVNET earned the award for its CryoFlux PowerCable, an innovative solution that tackles the persistent issue of heat generation during EV charging.

The CryoFlux PowerCable is the industry’s first to implement liquid evaporation phase-change cooling technology, maintaining ultra-low temperatures inside the cable to minimize energy loss. This breakthrough drastically reduces the cable’s weight to under 10kg and resolves both overheating and bulkiness, enabling safe and efficient megawatt-level charging.

TMEVNET is a promising startup nurtured within the Cheonan-Asan Innopolis Special R&D Zone, with the Korea Automotive Technology Institute (KATECH) serving as its key technology partner. Through a region-specific global expansion program supported by the zone, TMEVNET challenged for and secured the prestigious CES 2025 Innovation Award.

Following the award, TMEVNET plans to further enhance its technological capabilities through joint R&D with KATECH, while also conducting PoC (Proof of Concept) testing in collaboration with Mercedes-Benz and Siemens in Germany to validate CryoFlux performance in the European market.

“We are honored to be recognized at CES for our technology,” said Hyungnam Cho, CEO of TMEVNET. “With CryoFlux, we aim to redefine the standard for megawatt charging in the era of future mobility.”

Meanwhile, TMEVNET was recently selected for the Deep-Tech TIPS program in partnership with the Korea Automotive Technology Institute, securing up to KRW 1.5 billion in R&D funding. The company intends to leverage this support to further advance CryoFlux performance and strengthen its global competitiveness.
