Chinese automaker Changan Auto has developed a detachable turbine generator capable of transforming conventional electric vehicles (EVs) into extended-range electric vehicles (EREVs), a move that could address range anxiety and charging infrastructure limitations. The innovation, originating from Changan’s Hunan Tyen subsidiary, offers a solution for drivers facing limited access to charging stations.
The system functions as a removable generator that increases a vehicle’s energy capacity without requiring structural modifications to the car itself, according to company statements. Changan leveraged its expertise in fluid machinery design and advanced numerical simulations to create the turbine. Analysis of compressor and turbine internal flows was conducted using three-dimensional modeling, alongside the development of high-efficiency bearings and blade systems, resulting in a performance increase exceeding 5%.
The technology is not limited to passenger vehicles; Changan envisions applications for drones and other mobile equipment. The company’s approach aims to reduce reliance solely on battery power, offering a flexible alternative for extending vehicle range. The turbine’s design prioritizes high power density, a compact structure, and compatibility with various fuels.
The launch of the A06 sedan, featuring this technology, highlights Changan’s commitment to expanding the possibilities of electric vehicle ownership. The turbine system represents a novel approach to addressing the challenges of EV adoption, particularly in regions with underdeveloped charging infrastructure.
