On July 23, the "2025 Qi2.2 Wireless Charging New Technology Seminar," hosted by Charging Head Network, concluded successfully online. As an annual flagship event in the wireless charging field, this seminar brought together numerous leading industry companies to discuss the latest advancements and future trends of Qi2.2 technology.

Mr. Huang Gang, Product Marketing Manager at NuVolta Technologies (Hefei) Co., Ltd., was invited to participate and delivered a keynote presentation titled "Driving the Popularization of Qi2.2: Product Innovation is NuVolta's Endless Driving Force." He shared NuVolta's innovative achievements and industry insights in the Qi2.2 technology domain.

Qi2.2 Technology: A New Milestone in Wireless Charging / MILESTONE

As the latest standard released by the Wireless Power Consortium (WPC), Qi2.2 further optimizes charging efficiency, compatibility, and safety, opening up broader possibilities for consumer electronics, automotive, medical, and other fields. In his speech, Huang Gang emphasized that the popularization of Qi2.2 is not just a technological iteration but a comprehensive upgrade of the user experience. The core of achieving this goal lies in continuous product innovation and ecosystem collaboration.

NuVolta's Innovation Practice: From Chips to Solutions / INNOVATION

As a pioneer in the wireless charging field, NuVolta Technologies has always been driven by technological innovation, dedicating itself to Qi2.2 technology R&D. Huang Gang announced that NuVolta has obtained certification for four of the first batch of Qi2.2 products.

NuVolta's Qi2.2 solutions have not only passed rigorous WPC Plugfest tests but have also made breakthroughs in the following areas:

• High Integration
      Integrates the protocol chip, main controller, phase demodulation, and other modules into a single chip (e.g., NU6801), reducing peripheral components and PCB area; supports wired/wireless charging integration, simplifying customer design processes.
• Intelligent Demodulation Technology
      Significantly improves charging success rate and stability through multi-mode demodulation algorithms (e.g., VDM demodulation, load-adaptive parameter configuration).
• Thermal Optimization
      Utilizes new packaging (e.g., specific "package" designs) to increase heat dissipation paths, achieving a 5% temperature reduction under equivalent conditions and supporting sustained high-power output.
• Performance and Compatibility
      Supports the PPS protocol, low-power mode, and optimized EMI performance, ensuring compatibility with multi-brand devices.
• Cost-Effectiveness
      Reduces BOM cost and PCBA complexity through integration and packaging innovations, accelerating mass production.

Industry Collaboration: Building the Qi2.2 Ecosystem Together / COLLABORATION

During his speech, Mr. Huang Gang also mentioned the concept of "Ecosystem Win-Win." He pointed out that the popularization of Qi2.2 requires industry collaboration – every step, from chip design and solution integration to certification testing, is crucial.

With NuVolta's CEO Michael being elected as a WPC Director and NuVolta's Li Zeng elected as Vice Chairman of the WPC 50W SWG, NuVolta hopes to contribute more effectively to the collaboration across the industry chain in the future.

Future Outlook: Innovation Never Stops / VISION

Huang Gang concluded, "The ultimate goal of wireless charging is 'invisibility' – making charging as natural as breathing." NuVolta's Qi2.2 solutions, centered on technological innovation and customer needs, address industry pain points in efficient charging, thermal management, and compatibility. "We firmly believe that product innovation is the endless driving force for promoting the standardization and popularization of wireless charging technology."

In the future, NuVolta will continue to focus on performance enhancement and cost control, providing the market with more competitive solutions.
