Serieshybridi

Serieshybridi, also known as serial hybrid or series-parallel hybrid, is an advanced automotive powertrain configuration that combines elements of both series and parallel hybrid systems. In a series hybrid, the internal combustion engine (ICE) is decoupled from the wheels and is used solely to generate electrical power, which is then stored in a battery pack. This electrical power is used to drive the vehicle's electric motor(s), which in turn propels the vehicle.

The series-parallel hybrid configuration extends this concept by incorporating a mechanical connection between the ICE and the wheels, allowing for both series and parallel operation. This hybrid configuration offers several advantages over traditional parallel hybrids. Firstly, it allows for more efficient use of the ICE, as it can operate at its most efficient point regardless of the vehicle's speed or load. Secondly, it provides improved fuel economy, as the electric motor can assist the ICE during acceleration and other high-demand situations, reducing the need for the ICE to operate at less efficient points.

However, series-parallel hybrids also have some drawbacks. The additional complexity of the powertrain can lead to higher manufacturing costs and potential reliability issues. Additionally, the use of a battery pack can increase the vehicle's weight and reduce its cargo space.

Series-parallel hybrids are used in various vehicles, including some luxury and performance-oriented models. They are also being explored for use in electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs), where they can help to extend the vehicle's range and improve its performance.
