What is the working principle of Lexus hybrid?

When starting the engine, you will notice an unusual quietness, with no engine noise audible at all. In fact, the engine has not yet begun to operate, and the central console display clearly shows the engine's working status. After starting the car, the electrical system inside the vehicle is activated. During low-speed starts, the engine does not need to be engaged at all; the electric motor, powered by the energy stored in the battery, can effortlessly move the car out of the parking space. The level of quietness throughout the vehicle is truly unimaginable. More relevant details are as follows: 1. Electric Motor: When preparing to depart, the engine remains off, and the two electric motors onboard begin to provide the power needed to move the car out of the parking space. With a slight press on the accelerator, such as when going uphill, the engine is immediately awakened, and the slight engine noise allows you to experience the surge of power. At this point, both the engine and the electric motor work together to propel the vehicle. Simultaneously, part of the engine's power is diverted to the generator set, which promptly charges the battery. 2. Cruising: When the vehicle is cruising at low speeds, since the battery has stored sufficient electrical energy, the system will automatically shut down the engine based on the vehicle's speed, allowing the electric motor to directly drive the vehicle forward, thereby achieving fuel savings.
I've always been fascinated by hybrid technology. The working principle of the Lexus hybrid system is the coordinated drive of the engine and electric motor. The engine primarily provides power during high-speed cruising while simultaneously charging the high-voltage battery via the generator; the electric motor takes the lead during low-speed or urban driving, offering quiet and zero-fuel-consumption propulsion. During braking or deceleration, the system can recover kinetic energy, converting it into electrical energy stored in the battery, thereby reducing energy waste. Pure electric mode enables zero emissions over short distances, with the control unit dynamically balancing the output of the engine and electric motor to ensure optimal efficiency. When driving such a car, I noticed remarkably low fuel consumption, approximately 4-5L/100km, saving half the fuel costs compared to traditional gasoline vehicles, with battery life extending over 10 years and requiring minimal maintenance. The overall design is efficient, environmentally friendly, and delivers smooth driving.
