A seeriahübriidsüsteemiga, or series hybrid system, is a type of hybrid electric vehicle drivetrain. In this configuration, the internal combustion engine does not directly drive the wheels. Instead, it acts solely as a generator to produce electricity. This electricity is then used to power an electric motor that propels the vehicle, or it can be stored in a battery for later use.

The primary advantage of a series hybrid system is its flexibility in engine operation. The internal combustion engine can be run at its most efficient speed and load, regardless of the vehicle's speed. This can lead to improved fuel economy and reduced emissions, especially in urban driving conditions where frequent stops and starts are common. The electric motor provides instant torque, resulting in smooth acceleration.

However, series hybrid systems also have drawbacks. The energy conversion process, from mechanical to electrical and back to mechanical, introduces some energy losses, which can reduce overall efficiency compared to parallel or series-parallel hybrid systems. Furthermore, the reliance on an electric motor for propulsion means that the vehicle's performance is dependent on the power output of the motor and the available energy from the generator or battery. The absence of a direct mechanical link between the engine and the wheels can also sometimes lead to a different driving feel compared to conventional vehicles or other hybrid types.
