What is a mild hybrid car?

Use of the electric engine

Microhybrid, mild hybrid, MHEV, are different names to refer to an improvement in the alternator of a conventional gasoline or diesel combustion engine vehicle, together with a small additional battery to store the recovered energy, but not the incorporation of an electric engine that can move the car. The function of the conventional alternator is to generate the necessary electricity for the vehicle's starter, lights and electronics. The improvement consists in the possibility of decoupling this generator from the engine when it is not necessary and thus saving fuel by not constantly braking it and only coupling it when the car brakes or decelerates (to generate electricity using kinetic energy) or as a momentary aid when accelerating (due to this generator can be reversible and help the combustion engine if it receives electricity instead of generating it). Additionally, and depending on the configuration of each vehicle, it can act on the Stop-Start mechanism and allow it to circulate with the combustion engine off, taking advantage of the inertia of the car when the accelerator is not pressed.
Compared to a hybrid car (full hybrid), the fuel economy with mild hybridization is less but it provides some of the benefits of hybrid technology, being less expensive to apply since it lacks the duality of propulsion engines.

Range of a mild hybrid car.

Electric and total range

The range of a mild hybrid car is similar to that of a non-hybrid car and dependent on the fuel tank for the combustion engine. It may be somewhat larger since this system improves the efficiency of the set.
Unlike a plug-in hybrid vehicle PHEV (electric range of about 50 km) and a hybrid vehicle HEV (electric range of a few km), a vehicle with mild hybridization MHEV does not have an electric engine capable of moving the car alone.
