seeriahübriidsüsteemist

A seeriahübriidsüsteem, also known as a series hybrid electric vehicle (SHEV), is a type of hybrid electric vehicle where the internal combustion engine does not directly power the wheels. Instead, the engine acts solely as a generator to produce electricity, which can then be used to charge a battery pack or directly power electric motors that drive the vehicle. This configuration separates the power generation from propulsion.

In a seeriahübriidsüsteem, the internal combustion engine is optimized for running at its most efficient speed and load, regardless of the vehicle's speed or acceleration demands. This generated electricity is stored in a battery, which then supplies power to the electric motors for propulsion. The battery can also be recharged by an external source, such as a charging station, making it a plug-in hybrid electric vehicle (PHEV) if it has this capability.

The primary advantage of a seeriahübriidsüsteem lies in its potential for improved fuel efficiency and reduced emissions compared to conventional vehicles. By allowing the engine to operate at its optimal point, it can burn fuel more completely. The electric motors provide instant torque, leading to smooth acceleration. Disadvantages can include the added weight and complexity of the dual powertrain, and the reliance on the internal combustion engine for electricity generation when the battery is depleted or if charging infrastructure is unavailable. Examples of vehicles that utilize series hybrid technology include some range-extended electric vehicles.
