“SHVS is a mild hybrid system”

Mild hybrid system is the simplest form of hybrid in which the electric motor can function as an additional power source to the engine. The electric motor cannot run the car alone. They can just move the car along with the engines while starting.

The system uses the Integrated Starter Generator (ISG). The ISG replaces the standard alternator and also supplements the power of the engine.

To make it simple,

It is a small generator that uses electricity from the battery to pass through the stator windings (copper wire coils) and create a magnetic field that causes the rotor to spin and start the engine. In reverse, the rotors spin when operating freely (when the engine is not in any load; going down from the flyover) and the spinning magnets within the stator windings create electricity, which can be stored in the battery for the later use. It is a small unit generally fixed between the engine and the transmission and can also be connected to crankshaft via a drive belt.

It is a relatively simple solution to boost up the vehicle’s efficiency. Earlier this technology was only used in expensive cars but its great to see that Maruti has opted for this technology even for their budget cars.

This SHVS:  mild hybrid system is fitted in the DDiS model (diesel version) and not on the petrol version as the diesel cars in India outsells the petrol counterparts and thus to improve the diesel mileage even more, SHVS is a smart move by Maruti.

The basic technological functions under the SHVS are –

  1. IDLE STOP START:

The engine stops automatically when the car is idle and silently starts when the clutch is pressed. This helps in increasing fuel efficiency of the car.

  1. BREAK ENERGY REGENRATION:

Breaking charges the special high capacity battery and generates the energy to assist the engine’s idle stop start function, helping the engine during acceleration.

  1. TORQUE ASSIST FUNCTION:

The regeneration of energy assists the torque function of the car. This helps the engine in providing optimal acceleration and performance.

  1. GEAR SHIFT INDICATOR:

It prompts the driver to efficiently change gears. This helps ensure a smoother ride and better fuel-efficiency.

Under the SHVS category, Maruti currently has two offerings in India : Maruti Ciaz SHVS and Maruti Ertiga SHVS.
