What is the working principle of the Honda CR-V hybrid?

The working principle of the Honda CR-V hybrid is that the engine serves as the primary power source, while the electric motor acts as an auxiliary power source. During startup and acceleration when the engine's fuel consumption is high, the electric motor assists in driving to reduce the engine's fuel consumption. Auxiliary power system: When the battery charge drops below 60%, the auxiliary power system activates. When the vehicle's energy demand is high, the auxiliary power system and the battery pack simultaneously supply energy to the drive system. When the vehicle's energy demand is low, the auxiliary power system not only provides energy to the drive system but also charges the battery pack. Hybrid vehicle incentive policies: Taking Guangzhou as an example, hybrid models listed in the energy-saving vehicle catalog have the right to display energy-saving license plates. The lottery success rate for these license plate quotas is as high as 60%.
The working principle of the Honda CR-V hybrid is quite ingenious. It employs a system called i-MMD, equipped with a gasoline engine and two electric motors. In most situations, the vehicle prioritizes electric drive: during low-speed starts or in traffic jams, the electric motor directly uses battery power to propel the car forward, while the engine remains completely idle, ensuring quiet operation and fuel efficiency. When you need to accelerate or climb a hill, the system detects the high power demand and starts the engine, but it doesn’t directly drive the wheels; instead, it powers a generator to produce electricity, which either charges the battery or directly supplies another drive motor. During high-speed cruising, the engine connects directly to the wheels via a clutch, reducing intermediate losses for greater efficiency. When decelerating or braking, the energy recovery system converts kinetic energy back into electricity, storing it in the battery, thus creating a cycle that conserves energy. The system continuously monitors vehicle speed, throttle input, and battery status, intelligently switching modes to ensure smooth and seamless driving, with an average fuel consumption of around 5L/100km. As a hybrid enthusiast, I find this design superior to the pure gasoline version—efficient and practical.
