How Does a Hybrid Electric Vehicle Work?
2 Answers
Hybrid electric vehicles work by utilizing both an internal combustion engine and an electric motor to power the vehicle, thereby improving fuel efficiency, comfort, and acceleration performance. In hybrid vehicles, the electric motor serves as an auxiliary power source to assist the engine, providing strong and smooth power during normal driving. Drivers can enjoy more powerful starts and acceleration while achieving higher fuel economy. Hybrid vehicles start using electric power, operating quietly with zero emissions and no fuel consumption. At low speeds, the engine provides the primary driving force, minimizing noise at low RPMs. During full acceleration, both the engine and electric motor work together, delivering swift and smooth acceleration. When decelerating or braking, energy is recovered and stored for reuse as electricity.
As a hybrid car owner for five years, the question I get asked most by friends is how this car works. Simply put, it's a teamwork between gasoline and electric systems. At startup or low speeds, it runs purely on electric motor, as quiet as driving an EV; when accelerating or overtaking, the engine kicks in instantly with powerful force; while waiting at red lights, the engine automatically shuts off for zero fuel consumption. The smartest part is converting braking and downhill energy into electricity stored in the battery - my Corolla Hybrid can go 900km on one tank. The battery only charges to about 80% to protect its lifespan. This switching logic is calculated in real-time by computer, requiring no manual operation at all, making driving exceptionally worry-free.
