The World's First Supercapacitor Pure Electric Off-Highway Wide-Body Dump Truck Commences Operations at Tengyuan Coal Mine

[Ordos, Inner Mongolia – April 21, 2026]   Man Yue Technology Holdings Limited ("Man Yue Technology" or the "Group"), in collaboration with Inner Mongolia Wanjiang Investment Co., Ltd. and Wanrui New Energy (Ordos) Co., Ltd., and supported by ecosystem partners including Changzhou Yikong, Chengdu Yikong, Great Wall Heavy Industry, Dongguan FNETech, and Shenzhen Olip, has successfully developed the world's first supercapacitor pure electric off-highway wide-body dump truck (mining truck). The vehicle recently completed full-condition testing at the Tengyuan Coal Mine in Ordos and officially commenced operations through a series of launch events. This milestone marks a revolutionary breakthrough in the electrification of mining transport equipment and opens a new chapter in the green and low-carbon development of China's mining sector.

Successful Launch and Operational Event

The launch event was executed with a well-organized and concise agenda. Attendees first visited the Tengyuan Coal Mine dispatch room to tour the intelligent command and dispatch center. There, they conducted in-depth research on the mining area's production organization, safety control, and intelligent dispatch operations, laying the groundwork for the deep integration of supercapacitor mining trucks into actual mining scenarios.

Subsequently, at the vehicle demonstration site, technical experts provided a professional presentation on the supercapacitor power system and the 105EH mining truck's core performance, technical advantages, and operational adaptability. This comprehensively showcased the innovative achievements and application value of the world's first supercapacitor wide-body truck.

In a solemn and enthusiastic atmosphere, leaders from all parties participated in a ribbon-cutting ceremony, marking the official deployment of the vehicle. Following the ceremony, the supercapacitor wide-body truck slowly drove into the operational area to begin its trial run, officially kicking off a new journey of green transportation in the mining zone.

Attendees also observed the fast battery-swapping workflow at the swapping station, directly witnessing the "efficient replenishment, swap and go" operational model. This fully validated the product's practicality and high efficiency in real-world environments.

Concluding the event, Wanjiang Investment, Man Yue Group, and Wanrui New Energy held a strategic partnership signing ceremony. The three parties will continue to deepen their comprehensive cooperation across technology R&D, product manufacturing, and market promotion to jointly drive the large-scale implementation of electrified mining equipment.

Core Advantages of the Supercapacitor Power System

The supercapacitor wide-body truck launched in this operation was coordinated by Man Yue Group and jointly manufactured by Wanrui New Energy and Wanjiang Investment. It is custom-designed for the extreme working conditions of open-pit mines, including short-distance high-frequency operations, heavy-load hill climbing, and complex environments.

The vehicle is equipped with Wanrui New Energy's proprietary ZHD 603V/3068F Supercapacitor Power System, which can directly interface with existing lithium battery swapping bases to achieve a low-cost upgrade.

Technical Specifications

Compared to traditional lithium iron phosphate (LiFePO4) battery power solutions, this supercapacitor power system offers significant advantages:

· Millisecond-level response to meet heavy-load, high-power demands.

· 500,000 to 1 million cycle life, far exceeding the lifespan of standard lithium batteries.

· -40°C to 80°C wide temperature adaptability, perfectly suited for freezing northern mining regions.

· Physical energy storage mechanism, cutting off the risk of thermal runaway at its root.

Economic Benefits and Environmental Value

Validated by field tests and official operations at Tengyuan Coal Mine, the vehicle perfectly aligns with the mining area's

"operate—unload—charge—operate" cycle. Boasting high attendance rates and strong stability, the comprehensive transportation cost is reduced by approximately 65% compared to traditional fuel-powered mining trucks, with a single vehicle reducing carbon emissions by over 108 tons annually.

Relying on energy recovery technology and an integrated "wind-solar-storage-swap" microgrid, the system achieves highly efficient utilization of green electricity and a low-carbon closed loop, providing core equipment support for Tengyuan Coal Mine's transformation into a zero-carbon smart mine.

Strategic Partnership and Future Outlook

The collaborative innovation and powerful alliance among Wanjiang Investment, Man Yue Group, and Wanrui New Energy have achieved breakthroughs across the entire chain of technology R&D, equipment manufacturing, and scenario application. The successful testing and deployment of the world's first supercapacitor wide-body truck indicates that China's supercapacitor power technology for mining equipment has reached an international leading level.

Looking ahead, taking the Tengyuan Coal Mine demonstration as a starting point, the three parties will continuously optimize product performance, promote serialized and large-scale applications, and deepen cooperation with mining areas nationwide. Together, they will empower the mining industry's green, low-carbon, safe, and efficient transition, making significant contributions to the realization of the nation's "Dual Carbon" goals.
