Atom Partners with U.S. Harbinger to Develop Ultra-Slim ICCU for Large Commercial Trucks, Accelerates North American Expansion

KOSDAQ-listed Atom is accelerating its push into the North American electric vehicle (EV) component market by launching a joint development project with U.S. electric commercial vehicle company Harbinger Motors to create an ultra-slim ICCU transformer for large electric commercial trucks. Following last year’s equity investment in Harbinger Motors, Atom is expanding the partnership to encompass the joint development of key EV components, raising expectations about whether the company will enter Harbinger’s supply chain.

Atom announced on the 24th that it has begun joint development of a 22-kilowatt-class ultra-slim ICCU transformer with Harbinger Motors.

The ICCU is a core EV component responsible for charging, power conversion, and management. The new product under development will offer 22 kilowatts of output—twice as much as the 11-kilowatt models typically used in passenger EVs—and is aimed at the high-power charging environment needed for large commercial trucks.

High-output ICCUs must effectively manage heat generation as power throughput increases, while also reducing the size and weight of components. Atom plans to enhance space efficiency and achieve superior thermal management in high-output environments by applying planar magnetic technology, which uses a thinner flat-type (planar) core compared to traditional wound-type transformers.

In particular, Atom aims for a power conversion efficiency of more than 97% in the 22-kilowatt-class product. As the component will be installed in large commercial vehicles, the company is designing it to meet vehicle-specific requirements such as vibration resistance and durability. At the mass production stage, Atom will implement automated manufacturing processes to ensure productivity and quality stability.

This collaboration follows Atom’s equity investment in Harbinger Motors last year. The company explained that what began as a simple investment has now developed into a strategic partnership for jointly developing core components to be used in next-generation electric commercial vehicles.

Harbinger Motors is a U.S.-based company that develops chassis platforms for medium- and large-sized electric commercial vehicles. The company is targeting the North American commercial vehicle electrification market in partnership with major global logistics firms such as FedEx.

Atom, which has maintained a technology collaboration with Harbinger Motors, recently completed an on-site assessment of its production plant in Vietnam and has now launched this joint development project in earnest. If the products developed are selected for Harbinger’s electric commercial vehicle platform, the company hopes this will lead to actual mass production project contracts.

Atom is also expanding its EV component business portfolio from passenger to commercial vehicles. The company has previously targeted the 11-kilowatt and 22-kilowatt EV ICCU market in Korea by collaborating with domestic EV component firms such as Hyundai Mobis and LS Automotive. Now, Atom is extending its business scope to the North American large commercial truck market.

The company is also working to expand its manufacturing base. Atom recently completed a rights issue at a subscription rate of 101.11%, raising 14 billion won. Atom plans to use the proceeds to fully automate all production lines at its Vietnam manufacturing base, preparing for global-scale production of EV components.

An Atom official commented, “Our equity investment in Harbinger Motors has led to a substantial technology collaboration on the joint development of 22-kilowatt-class core parts for large commercial vehicles. Based on ultra-slim, high-efficiency power conversion technology, we will step up our efforts to target the North American and global electric commercial vehicle markets.”
