R&D patents

Decades of extensive experience in entrepreneurship and sustainable operations, coupled with proven management capabilities, have established a stable, efficient, and standardized operational management system.

The Wuling and Chenglong series of electric vehicles are equipped with a central computer control processor and boast more than 60 national invention patents. They employ advanced variable-frequency motor technology and regenerative braking, enabling them to tackle steep inclines while delivering exceptional range—core technologies that set them far apart from other EVs. The company’s products feature long driving ranges (with a range of 80–300 kilometers depending on the model), low operating costs (less than 5 cents per kilometer), and easy maintenance. The company collaborates closely with motor manufacturers and component suppliers to jointly develop high-performance sine-wave controllers that deliver outstanding hill-climbing capability, resulting in the launch of several models in the “Changpao Wang” series—ideal for the road conditions found in the Yunnan-Guizhou-Sichuan region. In 2013, the company conducted multiple long-distance road tests and successfully organized the “Chenglong Electric Vehicle 500-Li National Marathon Challenge: One-Charge, Endurance Run Across China,” held in partnership with dealers nationwide. During the event, the Liuzhou–Nanning leg alone exceeded 606 li, demonstrating the remarkable technological prowess of Chenglong electric vehicles as they traversed the entire Guangxi region. All of the company’s electric vehicles are manufactured using state-of-the-art, standardized assembly-line processes, with rigorous quality control at every stage of production and inspection. Each vehicle undergoes multiple inspection procedures before leaving the factory. Equipped with advanced professional tools such as motor dynamometers and battery testing and repair machines, the company accurately measures and records the key technical parameters of every critical component, ensuring that every vehicle delivered to customers is a high-quality, reliable electric vehicle.
