Tonhe Technology Showcases Industry-Leading Charging Solutions at EV TREND KOREA 2025

[Seoul, Korea-June 3-5, 2025]-Tonhe Technology made a strong impression at EV TREND KOREA 2025, the nation's premier exhibition for new energy vehicles and battery industries, held at COEX Convention & Exhibition Center in Seoul. Led by the Seoul Metropolitan Government, the event gathered top-tier manufacturers and technology innovators from around the globe.

Tonhe presented a full lineup of cutting-edge power modules, including:

40kW Taihang Series Charging Module (Overseas Edition)

40kW Liquid-Cooled Charging Module

30kW DC/DC Converter

With the theme of "Low Noise, High Protection, Ultra-High Efficiency", Tonhe's technology matrix attracted strong interest from global buyers, offering forward-looking solutions for the rapidly evolving EV charging landscape.

Surging Demand in Korea: Fast-Charging Subsidies Drive Growth

Korea plans to install 500,000 EV chargers by 2025, including 100,000 new units. The proportion of ultra-fast chargers (350kW class) is rising, supported by government incentives:

KRW 618.7 billion allocated for charging infrastructure (↑43% YoY)

Subsidy for 350kW ultra-fast charger: KRW 82 million (↑30% vs. 2024)

Subsidy for 100kW fast charger: Increased from KRW 20 million to KRW 26 million

This policy boost is driving significant opportunity for high-efficiency, low-noise solutions like those offered by Tonhe.
