From May 13 to 15, the 5th Shanghai International Charging Pile Battery Swapping and Solar-Storage-Charging Exhibition 2026 (CPSE) concluded successfully at the Shanghai Automotive Exhibition Center. Under the theme “Solid-State Transformer (SST) Defines New Efficiency for Charging & Swapping,” WG Energy unveiled four full-scenario SST charging solutions: the MCS SST megawatt flash charging solution, the high-efficiency charging solution for heavy-duty trucks, the solar-storage-charging solution, and the integrated solution for highway service areas. The three-day exhibition was packed with highlights, marking a successful conclusion.

01 Grand Opening, Technical Booth Presentations

On the first day of the exhibition, a technical expert from WG Energy delivered a keynote speech titled “SST Redefines the EV Charging Ecosystem: Anchoring Reliability for Full Lifecycle Returns” at the company’s booth.

The speech focused on how SST reshapes the profitability model of charging stations from a “full lifecycle returns” perspective, highlighting its core advantages in areas such as transformer-free capacity expansion, efficiency leap, modular reliability, and operation & maintenance costs. Drawing on real-world data from already operational projects in Kunshan and Linyi, the expert demonstrated the predictable returns and long-term reliability that SST can deliver for charging operators. Packed with actionable insights, the presentation sparked lively discussions, with the audience actively raising questions and engaging in a dynamic interaction.

Customers from across the country inquired in detail about WG Energy's SST technical specifications, certification progress, and delivery capabilities, showing strong interest in its applications in heavy-duty truck ultra-fast charging, integrated PV-storage-charging systems, highway service areas, and other scenarios.

02 Signings + World Premiere: Co-creating Charging Ecosystem

On the morning of May 14, WG Energy reached its highest-profile moment at the exhibition, as strategic signing ceremonies with Hunan Jingneng New Energy Technology Co., Ltd. (CJNOO) and Xinjiang Xindianhui New Energy Technology Co., Ltd. were held grandly at Booth D80.

As a leading player in the heavy-duty truck charging sector, CJNOO jointly released with WG Energy the industry’s first true HV direct-connected full-link integrated DC bus solution centered on a SST. Built around WG Energy’s SST, the solution achieves direct conversion from 10 kV to 750 V DC, with a real-world charging efficiency of over 95%, 40% less floor space, and a two-day delivery time — marking the official entry of HV direct-connected charging technology into large-scale commercial application.

Xinjiang Xindianhui New Energy has been deeply cultivating the new energy market in Northwest China. This signing marks that WG Energy's SST solution will accelerate its deployment along the Xinjiang and western logistics trunk lines, supporting the construction of a green logistics corridor on the Silk Road.

03 Honor + Industry Media Interview: Top 10 Investment‑Worthy Brand in the Industry Award

At the award ceremony held alongside the exhibition, WG Energy won the "Top 10 Most Investment‑Worthy Brands in China’s EV Charging & Battery‑Swapping Industry 2026" award, thanks to its technological leadership in SST, large-scale delivery capabilities, and clear business model. This honor not only recognizes the company's achievements over the past three years driven by its "technology + industry" dual-engine strategy, but also highlights the strong recognition from capital markets and the industry regarding WG Energy's future growth potential.

During the three-day exhibition, several industry media outlets, including International Energy Network, Charging & Battery Swap Research Institute, and Yiwa Energy Huangshan, conducted live broadcasts or interviews. They focused on hot topics such as how SST solves the grid capacity anxiety of ultra-fast charging stations, and how the full-DC coupling scheme improves charging efficiency while reducing energy losses. The interview content will be released on major media platforms soon. Stay tuned.

04 Successful Closing – Sustained Strong Booth Engagement

On the final day of the exhibition, the WG Energy booth remained busy. Many charging operators, logistics companies, and energy investors came to inquire about details of the SST solution, and quite a few customers made on-site arrangements to visit the demonstration station after the event. Technical experts and the sales team stayed at the booth throughout the day, patiently answering key questions about heavy-duty truck ultra-fast charging, solar-storage-charging coupling, and grid-connection without capacity expansion, bringing the exhibition to a successful close.

Conclusion

Three days, four highlights – awards, speeches, signings, and launches. With four SST-based full-scenario charging solutions, WG Energy demonstrated to the industry its solid progress in SST – from technological leadership to large-scale commercialization.

Going forward, WG Energy will continue to deepen its core SST technology, partnering with more industry players to deliver "high-efficiency, grid-expansion-free, and fast-deployment" solutions for charging and swapping infrastructure — ensuring every kilowatt-hour of electricity delivers maximum value at charging and swapping stations.
