What is the working principle of hybrid electric vehicles?

[JourneyAnn]

Hybrid electric vehicles work by utilizing both the internal combustion engine and the electric motor within the vehicle to provide power, thereby driving the car forward. This results in certain improvements in fuel economy, comfort, and acceleration. Hybrid electric vehicles use an electric motor as an auxiliary power source to assist the engine in driving the car. The electric motor can generate strong and smooth power during normal driving. The engine and the electric motor have complementary roles. If the engine is operating in its optimal state, the engine works alone. If the engine is not in its optimal state, the electric motor begins to assist. The goal is to keep the engine operating in its optimal state at all times, thereby achieving the lowest fuel consumption. Hybrid electric vehicles combine fuel and electric power. The electric motor delivers strong torque at low speeds, providing power for vehicle start-up and acceleration. As the speed increases, the internal combustion engine's output power and torque continue to rise, providing power for mid-to-late-stage acceleration.
