What is the Meaning of Mild Hybrid in Cars?

[McTalia]

Mild hybrid refers to mild hybrid electric vehicles (MHEVs), which alter the traditional power output method of cars, resulting in minimal vibration and noise when starting the vehicle. Hybrid generally refers to the combination of fuel and electric power. The output characteristics of internal combustion engines and electric motors are opposite: electric motors can deliver strong torque at low speeds, providing ample power for vehicle acceleration from a standstill. In contrast, internal combustion engines increase their power and torque output as the engine speed rises, supplying power for mid-to-high-speed acceleration. Mild hybrid vehicles feature a power recovery system. When braking, this system recaptures wasted energy to charge the vehicle's battery, achieving energy-saving and emission-reduction effects. Types of Hybrid Electric Vehicles: Series hybrid electric vehicles (SHEVs) primarily consist of three major powertrain components—engine, generator, and drive motor—connected in series to form the HEV powertrain system. Parallel hybrid electric vehicles (PHEVs) utilize both the engine and drive motor as power sources, allowing their power outputs to be combined or used independently. Power-split hybrid electric vehicles combine the structures of series and parallel hybrids, consisting mainly of three powertrain components: engine, electric generator, and drive motor.
