Semi hybrid

A semi hybrid vehicle is a vehicle that has a higher degree of hybridisation than a simple start-stop system but cannot operate in full electric mode. The following types of hybrid vehicles are available:

• micro hybrids;
• semi hybrids;
• full hybrids.

Principle of the semi hybrid vehicle

This type of vehicle has a start-stop system, a battery and an electric engine. The battery is recharged by an alternator coupled to the internal combustion engine and by the electric engine which operates as a generator during phases of regenerative braking.

The electric engine is used to start the vehicle and assist the internal combustion engine when it needs additional power during acceleration.

Moreover, the electricity produced and stored by hybrid motorisation powers several systems, such as lighting, on-board devices, etc.
