Atom Advances Tesla Cybertruck 'ICCU Slimming' Technology, Initiates Joint Development with LS Automotive

KOSDAQ-listed company Atom is advancing its ultra-slim planar transformer technology for electric vehicle (EV) integrated charging control units (ICCUs), drawing on the flat transformer structure implemented in the Tesla Cybertruck. Building on its collaboration with Hyundai Mobis, Atom is now undertaking joint development with LS Automotive, moving in earnest to enter the global automotive supply chain.

On August 21, Atom announced that it is pursuing the development of next-generation ultra-slim planar transformers for 11-kilowatt (kW) and 22kW class ICCUs in partnership with automotive electronic component specialist LS Automotive.

This joint effort focuses on reducing the size and weight of ICCUs by benchmarking the printed circuit board (PCB)-based flat transformer structure adopted by the Tesla Cybertruck. Atom explained that it completed its analysis of the Cybertruck’s transformer structure in June and has since validated its own planar transformer technology, which addresses heat dissipation and durability issues under high-output conditions.

An ICCU is a key electronic component in EVs, responsible for charging, power conversion, and management. As lightweight and compact components become more important to increase EV driving range and space efficiency, technology that maintains high output performance while reducing volume is emerging as a new competitive factor.

Atom and LS Automotive are aiming for an ultra-slim structure that reduces the height of the core component to within 30 millimeters, compared to the approximately 60 millimeters of conventional wound transformers. By halving the component’s height, their plan is to maximize ICCU internal space utilization while achieving miniaturization and weight reduction for the overall system.

Unlike wound transformers, planar transformers employ a flat structure. Atom plans to optimize the current path and control heat generated under high-output conditions through this approach, while also strengthening cost and quality competitiveness via automated production.

Notably, Atom is pushing forward with building a fully automated production line based on its ultra-slim planar transformer technology. The company expects that, if this technology is adopted in mass-produced 11kW and 22kW ICCUs in the future, it will achieve a proven case for the commercialization of ultra-slim planar transformers.

The ultimate objective of this collaboration is to secure entry into the next-generation EV platforms of global automakers. By combining LS Automotive’s electronic system development and manufacturing capabilities with Atom’s planar transformer technology, the two companies plan to develop and validate products before expanding their business to the global automotive supply chain.

According to the company, once automotive electronic components are adopted by automaker platforms, mid- to long-term supply can be secured in line with vehicle mass production cycles, enabling stable revenue streams if mass production materializes.

Atom has also been accelerating the expansion of its global automotive electronics customer base. Following its registration as a first-tier supplier to Hyundai Mobis and winning related orders, the company is further enlarging its client base in the EV electronic component business through this new joint development with LS Automotive.

Atom is simultaneously investing to expand production capacity. The company recently secured 14 billion won in growth funds through a paid-in capital increase, which will be used to automate production lines at its manufacturing base in Vietnam. It also plans to leverage the precise electronic component fabrication capabilities of its subsidiary, DST, to respond to future large-scale mass production.

An Atom representative stated, "This project is significant in that it extends the proven miniaturization technology for power conversion components, verified through the Cybertruck, to mass-produced EV platforms of global automakers. We plan to use this opportunity as a bridgehead to further expand our customer base among global car manufacturers."

Atom CEO Taeksoo Han commented, "Our joint development with LS Automotive will be a crucial milestone in expanding Atom’s planar transformer technology into the global automotive market. By leveraging our ultra-slim, high-efficiency power conversion technology and automated production competitiveness, we will continue to bolster our presence in the next-generation automotive electronics market and grow our global customer base."
