News & Activities

The tide of the times surges forward, sweeping the world with an energy transition revolution. Efficiency and sustainability have become core imperatives for urban development, while the relentless growth in smart power supply demands urgently calls for integrated solutions with core competitiveness. Since its establishment in 2017, Tongyu Communications' Energy Division has dedicated eight years to deepening expertise in the charging and battery swapping sector. Through its end-to-end integrated product solutions, it has redefined the standards for battery swapping services, injecting robust momentum into the high-quality development of the green energy industry.

The foundation of exceptional quality stems from continuous exploration of cutting-edge technology. The division has established a dedicated R&D team, leveraging modern research laboratories to focus on critical areas such as core algorithm iteration and structural optimization upgrades. With hundreds of authorized domestic and international patents, it has built a robust technological barrier. Recognizing the diverse needs of different application scenarios, the division rejects a one-size-fits-all standardized approach. Through deep collaboration and communication with customers, it dynamically optimizes design parameters to tailor exclusive battery swap cabinet solutions for diverse environments like residential communities, commercial complexes, and industrial parks. This ensures every product precisely addresses the pain points of its specific application.

Our commitment to quality begins with rigorous control over every raw material. The division has established a comprehensive supply chain screening system, conducting thorough qualification reviews and on-site verification of partners. Critical components are exclusively sourced from world-leading strategic suppliers such as CATL and Infineon. From core chips to energy storage cells, all materials are affixed with traceable QR codes throughout the entire process. This enables full lifecycle traceability management from procurement and warehousing to production and assembly. Standardized processes eliminate quality risks at the source, fulfilling our solemn commitment to quality.

Stepping into Tongyu's intelligent manufacturing facility, the spacious, clean dust-free workshop reveals high-precision SMT placement lines operating at high speeds. Robotic arms execute assembly and soldering processes with precision, while AGV smart logistics vehicles automate material transport. Automated production lines seamlessly coordinate with intelligent management systems. Every production step strictly adheres to standardized operating procedures. Visual production boards display real-time core metrics like daily output and yield rates, transforming complex manufacturing processes into a precise, controllable standardized system. This approach not only ensures scalable, high-efficiency mass production but also guarantees consistent quality and reliable stability for every product leaving the factory.

The ultimate inspection before delivery serves as the final line of defense for quality assurance. The division has established a multi-tiered quality control system covering the entire production process: incoming raw materials undergo rigorous testing including spectral analysis and precision dimensional measurement; real-time online quality monitoring is implemented during manufacturing; finished products endure extreme environmental testing far exceeding industry standards, such as aging tests, high-low temperature cycling tests, waterproof and dustproof tests, and charge-discharge cycle tests. Multiple authoritative certifications, including CE, UL, and ISO9001, serve as robust technical endorsements for the division's commitment to “zero-defect delivery.”

Eight years of dedicated cultivation have yielded fruitful results benefiting the world. Leveraging the headquarters' mature global sales and service network, the division's premium products have reached over 10 countries and regions worldwide. Its product portfolio spans the full spectrum of new energy solutions, including photovoltaic storage, embedded energy storage, EV charging/swapping cabinets, and charging piles. Long-term strategic partnerships have been established with industry leaders such as China Tower.

Looking ahead, Tongyu Energy Division will continue leveraging its robust R&D resources, end-to-end quality control capabilities, and customized product solutions to empower the widespread adoption of green energy. By collaborating with global partners, we will jointly build a sustainable future, illuminating every city with green power and accelerating the global energy transition toward achieving the dual carbon goals!
