How Does a Non-Plug-In Hybrid Vehicle Work?
2 Answers
Non-plug-in hybrid vehicle working principle: The vehicle is driven by both an internal combustion engine and an electric motor. At low speeds, the electric motor powers the car using electricity from the battery. At high speeds, both the internal combustion engine and the electric motor work together to provide power. The battery's electricity comes from a generator driven by the internal combustion engine. When the car brakes or decelerates downhill, the generator acts as a resistance to recover the vehicle's kinetic energy and converts it into electrical energy stored in the battery. The commonly referred to hybrid generally means a gasoline-electric hybrid, which is a combination of fuel and electric power. Hybrid vehicles use an electric motor as an auxiliary power source to assist the engine. Moreover, the electric motor assisting the engine can generate strong and smooth power during normal driving, allowing the owner to enjoy more powerful starts and acceleration.
From the internal mechanism of a non-plug-in hybrid vehicle, it operates quite ingeniously. I understand that its core is the combination of a gasoline engine and an electric system, eliminating the need for external charging. The engine's primary function is not to directly drive the wheels but to act as a generator to charge the battery; the electric motor propels the vehicle at low speeds or during startup. The key lies in the regenerative braking system—whenever you press the brakes, the kinetic energy that would otherwise be wasted is converted into electricity and stored in the battery. The computer control unit adjusts the energy flow in real-time, such as using the engine for efficient driving at high speeds and the electric motor in congested areas, thus avoiding fuel consumption from engine idling. The battery pack is designed to be small yet durable, maintaining its health through continuous charge-discharge cycles. This integration saves over 30% more fuel than pure gasoline vehicles, emits less pollution, and makes daily driving more environmentally friendly and economical.
