(1) Problem Definition / Development Background

As e-Mobility expands, vehicles require efficient power conversion systems to bridge high-voltage traction batteries and low-voltage electronic subsystems.
Existing converters face challenges of thermal efficiency, size, and communication reliability under real driving conditions.

(2) Value Proposition / Solution

GNT’s LDC solutions offer:
- Compact, lightweight structure reducing design complexity.
- Stable power output even under load fluctuation.
- Efficient cooling and high protection rating (IP67).
- Automotive-grade reliability and durability proven through field validation.

Core business: Design and production of LDC converters for EV/HEV/H₂ platforms.
Expanding supply partnerships with domestic and global automotive OEMs.
Preparing for IPO and export certification to strengthen global competitiveness.
Developing next-generation 3.0 kW+ LDC systems for high-capacity EVs.

(1) PoC Progress

GNT is preparing international PoC projects with key overseas OEMs and system integrators to validate performance of its 1.8 kW water-cooled and 1.0 kW air-cooled LDCs under diverse operating environments (temperature, humidity, vibration).
Target regions for initial PoC include Japan (EV/HEV component testing), Europe (hydrogen mobility platforms), and Southeast Asia (bus and logistics fleet electrification).
Each PoC focuses on evaluating power conversion stability, CAN communication reliability, and thermal efficiency under local standards.

(2) Global Expansion

GNT plans to establish strategic partnerships with automotive OEMs and Tier-1 suppliers in Europe and Asia to supply its LDC systems for hydrogen-fuel and e-mobility platforms.
The company is pursuing technology export and joint-development programs with Japanese and European EV manufacturers, leveraging its compact, IP67-certified converters as high-reliability solutions for harsh conditions.
Medium-term (2025–2027): build overseas branches for after-sales service and localization of LDC manufacturing, starting with Japan and the Czech Republic.
Long-term (2028 onward): expand into North America and the Middle East, integrating next-generation 3.0 kW+ converters into heavy-duty and hydrogen commercial vehicles.
