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.

As an automotive technology enthusiast with a deep understanding of hybrid vehicles, I've extensively researched, followed the advancements, and have hands-on experience working with hybrid systems. Over the years, I've studied the evolution of hybrid technology, its principles, and applications in various vehicles.
In the realm of hybrid vehicles, there are distinct classifications: micro hybrids, semi hybrids, and full hybrids. A semi hybrid vehicle, as described in the article, represents a higher level of hybridization beyond a mere start-stop system but lacks the ability to operate solely in electric mode. This type of vehicle integrates components such as a start-stop system, a battery, and an electric engine.
The semi hybrid's operational functionality involves a synergy of its components. The battery undergoes recharging through an alternator connected to the internal combustion engine and also via the electric engine, which functions as a generator during regenerative braking phases. Notably, the electric engine is responsible for initiating the vehicle's start and supports the internal combustion engine during acceleration by providing additional power.
Furthermore, the hybrid motorization system's electricity production and storage play a pivotal role in powering various vehicle systems beyond the propulsion, including lighting, on-board devices, and other auxiliary functions.
Regarding the concepts mentioned in the article:
-
Micro hybrid: This refers to a vehicle with a basic start-stop system designed to conserve fuel by shutting off the engine during idle times and restarting when needed.
-
Full hybrid: It represents a type of hybrid vehicle that can operate using only the electric motor, internal combustion engine, or a combination of both. Full hybrids offer the capability of running solely on electric power at lower speeds.
-
Secondary energy: This term often refers to stored or transformed energy used for various purposes, typically derived from primary energy sources.
-
Sensitive Natural Space: This could indicate a specific term related to environmentally or ecologically delicate areas that require special attention or protection due to their ecological significance.
-
Hybrid: A hybrid system combines two or more different technologies or power sources to achieve enhanced performance, efficiency, or functionality.
-
Semi-conductor: A semiconductor is a material with conductivity between that of a conductor and an insulator. It's crucial in electronics and forms the basis of most electronic devices.
-
Semi-crystalline polymer: This refers to a polymer material with a structure that contains both crystalline and amorphous regions, impacting its mechanical properties.
-
Semi-permeable membrane: A membrane that allows certain substances to pass through while blocking others based on size, charge, or other properties.
-
Hybrid hard drive: A storage device that combines traditional magnetic hard drive technology with solid-state drive (SSD) technology for enhanced performance and capacity.
-
Semi-major axis: In orbital mechanics, this refers to half of the major axis of an ellipse, describing the size of an elliptical orbit.
Understanding these concepts provides a comprehensive grasp of hybrid vehicles and related technologies, showcasing the diverse applications and interdisciplinary nature of hybrid systems in various fields.
