What is the principle of the Accord hybrid car?
3 Answers
The Accord hybrid system has three driving modes: pure electric, hybrid, and internal combustion engine driving. In electric mode, the motor obtains energy from the lithium battery pack and drives the vehicle alone. The maximum speed is 60 mph, and the maximum driving range is not high. Once the battery energy is exhausted, it automatically switches to hybrid mode. The following is an introduction to the hybrid system: 1. Hybrid mode: The working principle of the Accord hybrid is similar to that of the Chevrolet Volt. The 2.0-liter gasoline engine drives the generator to produce electricity, which is then used for the electric motor. Honda refers to the combination of the generator and the motor as a dual motor. In this mode, the vehicle is driven solely by the electric motor. Internal combustion engine driving mode: In this mode, the motor is decoupled from the transmission system. 2. The engine directly drives the wheels through a single-speed transmission. According to Honda, the efficiency of this single-speed transmission is similar to that of a 6-speed manual transmission under highway conditions. Atkinson cycle engines are also used in hybrid vehicles from Ford and Toyota.
The core principle of the Accord Hybrid operates through Honda's i-MMD hybrid system, which consists of a 2.0-liter gasoline engine, two electric motors, and a lithium-ion battery. The system automatically switches between pure electric mode, hybrid mode, and engine direct drive mode. When you lightly press the accelerator to start or drive at low speeds, it primarily uses the electric motor for near-silent and fuel-efficient operation; during acceleration or high-speed driving, the engine intervenes to drive or charge. The regenerative braking function recovers braking energy and stores it back in the battery. Combined with the e-CVT transmission, the driving experience is smooth and jerk-free. Its advantage lies in achieving over 30% fuel savings in urban commuting, with the engine operating only in its most efficient range. The design ensures low emissions and high responsiveness, making it more eco-friendly and intelligent compared to the standard Accord.
Every time I drive my Accord Hybrid, it feels effortless. The engine doesn't always start, especially in traffic jams where it quietly moves forward on electric power, like riding an electric scooter. When braking, it silently recovers energy and stores it in the battery for later use, with daily fuel consumption below 6 liters per 100 kilometers. On the highway, the system automatically switches to gasoline power but can still assist with electric motor power. The battery is hidden under the car without affecting space, ensuring a smooth and fuel-efficient drive overall. Even on long trips, there's no need to worry about charging—the hybrid combines the advantages of electric and gasoline cars, saving money and offering convenience.
