How Does a Dual-Power Hybrid Car Work?

[Jeff]

The working principle of a dual-power hybrid car is that during startup, the hybrid power system does not engage the engine; instead, it relies solely on the electric motor to provide the maximum torque instantaneously using electrical energy. During driving, it utilizes both the electric motor and the engine, maintaining the output power and fuel economy at their optimal levels. When decelerating or braking, stepping on the brake pedal transforms the electric motor into a generator, storing the recovered energy in the HV battery. Disadvantages: Higher price, with the same displacement costing about 40% more; difficult maintenance, as only major cities have the necessary repair facilities; reduced space and increased weight due to the additional battery system, which occupies significant space and adds to the vehicle's weight; operational drawbacks include the need to monitor battery charge levels and the requirement to manually shut off the electric motor when parking, as it cannot be turned off with a single button. Advantages: Hybrid models of the same displacement generally consume about 30% less fuel compared to traditional gasoline-powered cars.
