SoluM (CEO Jeon Seong-ho) has achieved a remarkable feat by pioneering export opportunities through CE certification for key components for electric vehicle chargers in a "trillion-won" market.


SoluM announced on the 18th that it has obtained CE certification for the Power Unit (PSU), a core component of electric vehicle chargers, for the first time in Korea.

While domestic companies are leading the way in electric vehicle charging infrastructure products in the global charging market, the power unit (PSU), which is the heart of the charger, is still heavily dependent on China.

In particular, in the case of fast chargers, the power module, a core component, is an expensive part that accounts for 40% of the charger's cost, yet dependence on Chinese products is virtually 100%.

As high performance and reliability are required due to its direct impact on the charger's output, the localization of power modules is urgently needed to minimize consumer damage and establish a stable supply chain.

In this market environment, it is considered encouraging that SoluM's 30kW power module for fast charging has simultaneously obtained CE and KC certifications.

The industry expects this certification to serve as a catalyst for leading domestic charger manufacturers to take their quality and performance to the next level.

In addition, SoluM's 30kW power module for fast charging is a Chinese product sold on the market It is significant that the chronic problems were resolved.

Unlike other products whose output efficiency drops as the external temperature rises, it has excellent heat resistance, allowing it to produce high output power even at temperatures up to 60 degrees, and it is slimmer and more compact than existing products, making it effective for reducing the size of electric vehicle chargers.

Furthermore, it guarantees a maximum efficiency of over 96% by applying SiC FETs, a next-generation power semiconductor. In addition, it is noteworthy that by assigning a separate ID to each module, defective modules can be immediately identified and replaced even in power banks containing multiple modules.

An industry insider explained, “Despite starting development relatively late, the fact that SoluM was able to complete a power module for high-speed chargers that possesses both performance and reliability the fastest must have been based on its high-power design and software technologies.”

With this certification, SoluM has met the basic requirements for entering both domestic and overseas markets and is focusing on securing new clients. It is reported that the company is currently in active discussions with global automakers regarding the construction of charging stations and the mass production of power modules for chargers. In addition, the company stated that it is continuing business model collaborations with retailers and local charging operators secured through its existing ESL business.

In addition, SoluM is accelerating its global expansion by acquiring UL (U.S. safety certification) within the year. Once the new factory in Mexico is completed, sales of power modules for electric vehicle chargers are expected to gain momentum.

Global market research firm QY Research forecasts that the global power module market will grow at an average annual rate of 33.5% to $2.233 billion (approximately 2.96 trillion won) by 2025, which means that securing the market first guarantees revenue in the trillions of won.

Yoo Dong-gyun, Head of SoluM’s Power Business Division (Executive Vice President), emphasized, “SoluM has built up High Power capabilities based on long-term research and development, and we believe that the market where we can fully utilize our accumulated technological know-how is ‘power modules for electric vehicle chargers.’ Now that we have secured a foothold for overseas expansion through this CE certification, we will mass-produce 30kW power modules within the year and launch a high-capacity 50kW power module model by the first half of next year, thereby achieving sales growth in new businesses as well.”
