SIX DEGREES OF ELECTRIFICATION

摘要

A micro hybrid has a conventional internal combustion engine (ICE) with a "stop/start" I mechanism that kills the engine whenever it pauses in traffic. This means it needs a more powerful lead-acid battery and starter motor. Advanced versions use this not just to start the engine, but also to drive the car briefly after it restarts, when running an ICE is at its least efficient. Offered as standard on many new cars, it can deliver fuel savings of 5 to 9 per cent. It is not generally considered to be an electric vehicle.
