Hunan Tyen, a company associated with the Changan group, has developed a micro-turbine called the Power Turbine Generator (PTG). This technology can convert a fully electric vehicle into a range-extended electric model.

The turbine runs on fuel and serves solely as a generator. It doesn't drive the wheels but produces electricity to recharge the battery while driving. The vehicle's electronics activate the module only when needed, optimizing fuel consumption and efficiency.

According to the developers, using three-dimensional airflow modeling and modern bearings has increased efficiency by about 5% compared to traditional solutions. Special attention has been paid to the cooling system and thermal load management.

A key advantage of the PTG is its flexible integration. The module can be installed on both new models and existing electric vehicles. This opens the possibility to reduce battery capacity, lowering the vehicle's weight and cost, while maintaining long-distance capability thanks to the generator.

The developers believe the system could partially address issues like reduced range in cold climates and high energy consumption on highways. However, significant barriers remain, including certification requirements and regulatory restrictions in different countries.

Beyond the automotive market, the technology is being considered for large drones and specialized equipment operating in remote areas.
