Micro-Hybrid Vehicles use “Start-Stop Engine System,” where regenerative braking technology helps to stop a combustion engine when the vehicle pulls to a stop, and to restart it when the driver accelerates. There are several different versions of the system, which some are now calling the “simplest hybrid technology” on the international market. Start Stop Engine System is a system designed to make the optimum use of the fuel in Start-Stop conditions. Though initially the technology failed to impress many drivers due to its high cost, it was later accepted whole heartedly.

Working Principle of Micro-Hybrid Vehicles

Micro-Hybrid VehiclesA micro-hybrid vehicle is the simplest kind of gasoline/petrol-electric technology. It is commonly composed of an energy storage device—like a battery—and a beefed-up starter-motor that can also act as a generator. The car’s engine control unit shuts off the engine when the car slows down or comes to a stop. As soon as the driver puts in the clutch, moves the shift lever, or accelerates, the battery powers the starter motor, which quickly switches on the engine. Stopping the engine while vehicle is at idle conserves fuel, but one disadvantage to this type of system can be the noticeable starting and stopping of the engine.

A new generation of low voltage micro-hybrid technologies in vehicles could allow existing engine technology and transmission combinations to be downsized and support significant reductions in fuel consumption and CO2 emissions.

Micro-Hybrid Vehicles, also known as start-stop systems, use regenerative braking and battery storage to allow cars not to burn fuel while at a stop. Cars using stop-start do not provide propulsion to the wheels, but the technology is low hanging fruit—a cheap and easy way to get about 10 percent more miles per gallon. The cost of a micro-hybrid system can be as low as $500 per vehicle.
