en.Wedoany.com Reported - On April 28, 2026, the world's first supercapacitor pure electric non-road wide-body dump truck completed full-condition testing and officially entered operation at the Tengyuan Coal Mine in Ordos, Inner Mongolia, China. The vehicle was jointly developed by Wanrui New Energy (Ordos) Co., Ltd., Inner Mongolia Wanjiang Investment, and Hong Kong Wanyu Technology Group, with support from ecosystem partners such as Changzhou Econtrol and Great Wall Heavy Industry. The vehicle is equipped with Wanrui's self-developed ZHD 603V/3068F supercapacitor powertrain system.
The supercapacitor powertrain system operates within a voltage range of 450~756Vdc, has a nominal energy of 168.6kWh, a maximum continuous charge/discharge current of 2000A, and can charge to 80% in just 6.72 minutes. The system can be directly adapted to existing lithium battery swap bases, enabling low-cost upgrades. Compared to traditional lithium iron phosphate battery solutions, the supercapacitor boasts a power density exceeding 10kW/kg, more than 30 times that of lithium batteries; a cycle life of 500,000 to 1,000,000 cycles; an operating temperature range from -40°C to 80°C, with low-temperature capacity retention exceeding 80%; charge/discharge efficiency over 95%; and an IP67 protection rating.
In field tests at the Tengyuan Coal Mine, the supercapacitor wide-body truck demonstrated a high attendance rate, reducing comprehensive transportation costs by approximately 65% compared to traditional fuel-powered mining trucks, with an annual carbon emission reduction of over 108 tons per vehicle. The vehicle leverages energy recovery technology and an integrated "wind-solar-storage-swap" microgrid to utilize green electricity. Wanrui New Energy had previously delivered batches of YK105EH mining wide-body trucks to the Tengyuan Coal Mine, and the deployment of this supercapacitor model further completes its mining electrification product matrix. Following the commissioning, Wanjiang Investment, Wanyu Technology, and Wanrui New Energy signed a strategic cooperation agreement to promote the large-scale deployment of supercapacitor mining equipment.
