What is the Working Principle of a Range-Extended Hybrid?

[MacAshlyn]

Range-extended hybrid works as follows: 1. The car is driven by an electric motor, also known as a series plug-in hybrid system. The internal combustion engine's role is to drive the generator to produce electricity, which powers the battery, motor, and other equipment in the car. 2. A range-extended electric vehicle is developed on the basis of a pure electric vehicle, with an additional range extender installed. 3. The purpose of installing a range extender is to increase the driving range of the pure electric vehicle and avoid frequent charging. 4. The engine speed of a range-extended hybrid does not need to match road conditions, ensuring that the engine can always operate within the most thermally efficient range, thus maintaining high fuel economy. However, compared to ordinary plug-in hybrid vehicles, range-extended hybrids consume more energy at high speeds, resulting in slightly poorer fuel economy performance.
