Product Highlights
|
30/40kW EV ChargingPowerModule Certified to IEC 61851-23:2023 by TÜV SÜDFully 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 ModuleUltra-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-fillingTechnologyTonhe Technology is the first in the industry to adopt fully automated double-sided PCB gel-fillingtechnology, 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 lowerschargingmodule 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,chargingmodules 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-fillingaddresses 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.
Looking ahead, Tonhe Technology will remain committed to innovation-driven growth, increase investment in R&D, and continuously optimize product performance and solutions to meet the evolving demands of the global new energy market. Leveraging international exhibitions, the company will further strengthen partnerships worldwide, expanding its global footprint and contributing to the advancement of the renewable energy industry.
