By continuously improving product efficiency, reliability, and system integration capabilities, Tonhe is dedicated to delivering advanced EV charging power modules and comprehensive charging solutions that empower global partners to build a greener,
Tonhe Technology successfully participated in the 19th Vietnam International Exhibition on Electrical Technology & Equipment (Vietnam ETE & Greenergy Expo 2026), held at the Saigon Exhibition and Convention Center (SECC) in Ho Chi Minh City.
As one of Vietnam's leading trade exhibitions for the power, renewable energy, energy storage, and EV charging industries, this year's event attracted more than 400 exhibitors from around the world across 15,000+ square meters of exhibition space. The exhibition brought together industry leaders to showcase the latest technologies driving Southeast Asia's energy transition.
At the exhibition, Tonhe Technology presented its latest 40kW and 50kW air-cooled EV charging power modules, 40kW liquid-cooled charging module, and complete EV charging solutions. During the three-day event, the company's booth welcomed numerous EV charger manufacturers, charging network operators, and distribution partners from Vietnam and across Southeast Asia.
Visitors engaged in in-depth discussions with Tonhe's technical team on charging module applications, advanced power conversion technologies, localized product development, and future cooperation opportunities. By delivering highly efficient and reliable power conversion products together with comprehensive technical support, Tonhe helps partners accelerate charger development and expand into the rapidly growing EV charging market.
Vietnam's EV Charging Market Continues to Accelerate
Vietnam is rapidly advancing its transition toward green transportation and has identified the electric vehicle industry as a strategic component of its national energy transformation and sustainable economic development.
Supported by favorable government policies, including tax incentives, investment encouragement, and infrastructure development initiatives, the country's EV charging network is expanding at an unprecedented pace.
In addition, Vietnam's National Power Development Plan VIII (PDP8) prioritizes renewable energy deployment and grid modernization, creating significant opportunities for EV charging infrastructure, power electronics, and energy storage technologies.
Beyond Vietnam, neighboring ASEAN markets—including Thailand, Malaysia, and Indonesia—are also accelerating investments in electric mobility and charging infrastructure, providing substantial growth opportunities for global EV charging solution providers.
High-Efficiency Charging Modules Designed for Diverse Applications
During the exhibition, Tonhe introduced its latest portfolio of high-performance charging power modules designed for different charging scenarios.
Class A Charging Modules for Commercial EV Charging Stations
For commercial and public charging applications, Tonhe introduced its latest 40kW and 50kW air-cooled charging modules with a unified mechanical design.
Both modules comply with Class A EMC standards and have obtained CE certification issued by TÜV SÜD. Featuring a peak efficiency of up to 97.3%, these modules help customers reduce product development complexity, shorten certification cycles, and accelerate project deployment.
Class B Charging Modules for Residential Charging Applications
For residential and community charging infrastructure, Tonhe showcased its 30kW and 40kW charging modules, also featuring a unified module size.
These products comply with Class B EMC standards and have received both CE and cTUVus certifications from TÜV. Delivering peak efficiency above 97.3% while maintaining an operating noise level as low as 60 dB, they provide an ideal balance of energy efficiency and quiet operation.
40kW Liquid-Cooled Charging Module for Ultra-Fast DC Charging
Tonhe also demonstrated its 40kW liquid-cooled EV charging module, specifically designed for high-power ultra-fast charging systems.
The module adopts an advanced liquid cooling architecture with a fully sealed enclosure, effectively isolating internal components from dust, moisture, and harsh environmental conditions. With an IP65 protection rating, the module delivers exceptional environmental adaptability and long-term reliability.
Combined with efficient liquid cooling technology and Silicon Carbide (SiC) power devices, the module achieves peak efficiency of up to 97.2%, while offering a design lifetime exceeding 10 years with virtually maintenance-free operation, helping operators significantly reduce total operating costs.
Turnkey EV Charging Solutions for Local Manufacturers
Recognizing that Vietnam's EV industry is developing rapidly while local charger R&D capabilities are still evolving, Tonhe also presented its complete EV charging solution.
Powered by Tonhe's self-developed main control system and SECC communication control system, the solution provides comprehensive technical support covering everything from core power modules to complete charger control systems.
This one-stop solution enables local power equipment manufacturers and new energy companies to shorten development cycles, lower engineering complexity, accelerate product commercialization, and rapidly establish competitive EV charging businesses.
Double-Sided PCB Potting Technology for Superior Environmental Protection
To address the challenging operating environments commonly found across Southeast Asia—including high temperatures, humidity, heavy rainfall, and coastal salt spray—Tonhe integrates its proprietary Double-Sided PCB Potting Technology into its charging modules.
The fully encapsulated PCB protection process creates a robust barrier around critical electronic components, significantly improving resistance to moisture, condensation, corrosion, and salt spray.
This advanced protection technology enhances system stability and reliability under demanding environmental conditions while reducing equipment failures and maintenance costs, ensuring long-term, safe, and efficient charger operation.
Driving a Greener and Smarter EV Charging Future
As the global transition toward sustainable transportation continues to accelerate, Tonhe Technology remains committed to innovation in EV charging power technology.
By continuously improving product efficiency, reliability, and system integration capabilities, Tonhe is dedicated to delivering advanced EV charging power modules and comprehensive charging solutions that empower global partners to build a greener, smarter, and more sustainable charging ecosystem.
