Tonhe Technology Shines at The Smarter E South America 2025

Event Background

Amid the booming development of the global smart energy sector, The Smarter E South America 2025 was held grandly from August 26–28, 2025, at the Norte Convention Center in São Paulo, Brazil. As a pioneer in the new energy industry, Tonhe Technology showcased a range of cutting-edge products, including TÜV SÜD–certified power modules, at booth BB1.35, drawing significant attention from professionals and industry leaders.

Recognized as the largest and most influential new energy and storage exhibition in South America, The Smarter E South America 2025 covered 65,000+ square meters, hosted 600+ international exhibitors (including over 200 Chinese companies), and welcomed more than 55,000 visitors. Many global industry leaders gathered to present their latest products, technologies, and solutions in the field of smart energy.

Positive Policy Trends Across South America

Stronger policy support: Governments promote growth through tax incentives, subsidies for EV purchases, and ambitious charging infrastructure targets.

Expanding infrastructure: Coverage is extending from major cities to highways and remote regions.

Focus on innovation: Acceleration of fast-charging, smart charging (e.g., V2G), and solar-storage-charging integration projects.

Public transport electrification: Countries such as Chile, Peru, and Brazil actively advance the adoption of electric buses.

Product Highlights

30/40kW EV Charging Power Module Certified to IEC 61851-23:2023 by TÜV SÜD Fully compliant with the latest IEC 61851-23:2023 international standard, with upgraded insulation for enhanced safety and reliability. No need for external devices (e.g., magnetic rings or filters) to meet EMC Class B requirements. Designed with SiC technology and magnetic integration, reducing winding component volume by 30%. Achieves ≥97.5% peak efficiency with full-load noise as low as 60dB, meeting the high-end product demands of overseas markets.
30kW DC-DC Charging Module Ultra-high efficiency: Peak efficiency ≥98%. Ultra-low noise: As low as 55dB, ideal for noise-sensitive environments such as residential and commercial areas. Wide voltage range: Supports 200–865Vdc input, adaptable to diverse battery systems and storage applications. Pre-charge circuit: Built-in input-side pre-charge for reliable battery protection.
Industry-First Double-Sided PCB Gel-filling Technology Tonhe Technology is the first in the industry to adopt fully automated double-sided PCB gel-filling technology, eliminating at least four manual handling steps and reducing risks during manufacturing. This ensures consistency and reliability. Process details: Silicone rubber with high viscosity is applied around the PCB edges, followed by low-viscosity silicone encapsulation covering the entire PCB at a 2.5mm thickness. Result: Significantly lowers charging module failure rates under extreme environments. Given South America's vast geography and diverse climates, charging equipment faces severe operational challenges. As the core of charging stations, charging modules directly determine maintenance costs: Amazon (Brazil): Hot, humid conditions may cause short-circuits from moisture. Pampas (Argentina): Dust intrusion disrupts circuitry. Coastal regions: Salt spray corrodes PCB components. Traditional triple-proof modules struggle in such conditions, leading to high maintenance costs. Tonhe’s double-sided PCB gel-filling addresses these challenges at the root, offering operators a reliable solution to reduce downtime and enhance profitability.

Outlook

Participation in The Smarter E South America 2025 marked a strategic step for Tonhe Technology in expanding global presence and strengthening brand influence. The exhibition delivered significant outcomes in product showcase, brand promotion, business cooperation, and market feedback.
