Serieshybridiin

Serieshybridiin refers to a type of hybrid vehicle powertrain architecture. In a series hybrid, the internal combustion engine (ICE) does not directly drive the wheels. Instead, its primary function is to act as a generator, producing electricity to charge a battery pack or directly power an electric motor. The electric motor is the sole component responsible for propelling the vehicle. This design allows the ICE to operate within its most efficient speed and load range, independent of the vehicle's speed.

When the battery is sufficiently charged, or when the vehicle is operating at lower speeds or loads, the electric motor can draw power directly from the battery. During periods of higher demand, such as acceleration or climbing hills, both the ICE-generated electricity and the stored battery power can be used to drive the electric motor. This arrangement offers potential benefits in terms of fuel efficiency and reduced emissions, as the engine can be optimized for power generation rather than variable driving conditions.

A key characteristic of series hybrids is the decoupling of the engine from the drivetrain. This means the driver does not experience a direct mechanical connection between the engine's RPM and the vehicle's speed, which can lead to a different driving feel compared to conventional vehicles or other hybrid types. Examples of vehicles that utilize or have utilized a series hybrid configuration include certain models of buses and range-extended electric vehicles.
