How hybrid motor car works?
A hybrid car (HEV) is based on the combination of an internal combustion engine (gasoline or diesel thermal engine) and one or more electric motors that use energy stored in batteries. These engines can operate jointly or alternately.
This combination allows to take advantage of the advantages of each type of energy while limiting the disadvantages. This saves fuel and reduces exhaust emissions without sacrificing performance.
Hybrid motorization systems can save fuel by stopping the thermal engine when the vehicle is in parking, idling at a traffic stop or when the electric motor’s energy is sufficient to power the vehicle without the assistance of the thermal engine. The battery also provides energy to the air conditioner and accessories while the vehicle is idling. If necessary, the thermal engine reengages to provide more power for acceleration.
Mixed hybrid car (mild hybrid)
Soft hybridization, also known as mild hybridization or micro-hybridization, uses a small 48V lithium-ion battery and alternno-starter to support the heat engine in order to save fuel, increase performance, or both.
However, the micro-hybridization system cannot propel the car using only electricity. The electric block is only used as a starter for the automatic Start & Stop system, which cuts the engine when the car stops to save fuel, such as in traffic jams or traffic lights. On some light-hybridized car models, the electric motor can also help the thermal engine maintain a constant speed of up to 120 km/h.
While considered a simpler and cheaper way to market hybrid technology, since all conventional vehicle models can be equipped with hybrid technology, micro-hybrid systems do not improve fuel consumption as much as full hybrid systems. The model economy is about 0.5 L/100 km compared to a conventional thermal vehicle.
