Solum (CEO Jeon Seong-ho) has achieved the feat of opening up export routes by obtaining CE certification for key components for electric vehicle chargers in the 'unit-level' market.


Solum announced on the 18th that it has obtained CE certification for the power module (PSU), a key component of electric vehicle chargers, for the first time in Korea.

Although electric vehicle charging infrastructure products led by domestic companies are gaining prominence in the global charging market, the power module (PSU), which is the heart of electric vehicle chargers, is still largely dependent on China.

In particular, in the case of rapid chargers, the power module, which is a key component, is an expensive component that accounts for 40% of the charger cost, but the dependence on Chinese products is virtually 100%.

As it is directly connected to the output of the charger, high performance and high reliability are required, and domestic production 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 certification.

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

Also, Solum's 30kW power module for fast charging is a Chinese product sold on the market. Its significance lies in the fact that it has solved chronic problems.

Unlike other products that have lower output efficiency when the external temperature rises, this product has excellent heat resistance and can produce high output power even at temperatures up to 60 degrees. It is also slimmer and more compact than existing products, making it effective in reducing the size of electric vehicle chargers.

In addition, it guarantees a maximum efficiency of over 96% by applying the next-generation power semiconductor, SiC FET. In addition, it is noteworthy that each module is given a separate ID, so that defective modules can be immediately found and replaced even in power banks that contain multiple power modules.

An industry insider explained, “Despite starting development relatively late, SoluM was able to complete a power module for a high-speed charger that boasts both performance and reliability most quickly thanks to its high-power design and software technologies.”

With this certification, SoluM, which has the basic requirements to enter both domestic and overseas markets, is focusing on securing new customers. It is known that it is currently actively negotiating with global automakers to build charging stations and mass produce power modules for chargers. In addition, the company said that it is continuing business model cooperation with retailers and local charging operators that it has secured through the ESL business.

In addition, Solum is accelerating its global expansion by acquiring UL (United States safety standard certification) within the year. The completion of the new Mexican plant is expected to provide momentum for increased sales of power modules for electric vehicle chargers.

Global market research firm Qway Research forecasted that the global power module market size would grow at an average annual rate of 33.5% to reach USD 2.233 billion (KRW 2.96 trillion) by 2025, which means that sales in the trillions are guaranteed if the market is taken over.

“SoluM has built up high-power capabilities through extensive research and development, and we believe that the market where we can make the most of our accumulated technological know-how is the ‘power module for electric vehicle chargers,’” said Yoo Dong-gyun, head of SoluM’s power business division (executive director). “Now that we have secured a bridgehead for overseas expansion through this CE certification, we will achieve sales growth in our new business by mass producing 30kW power modules within the year and launching a high-capacity 50kW power module model by the first half of next year,” he emphasized.
