Mitsubishi Electric Begins Mass-producing Auto Industry’s First Crankshaft ISG System for 48V Hybrid Vehicles

Mitsubishi Electric announced today that it has begun mass-producing the auto industry’s first crankshaft-mounted integrated starter-generator (ISG) system for 48V hybrid vehicles, which will be mounted in Mercedes-Benz vehicles. Compared to belt-driven starter-generators, the crankshaft-mounted motor produces higher output power and generates more power, which contributes to better fuel efficiency. The Newly developed transfer-molded power module for 48V systems reduces heat resistance and enhances durability.

The demand for 48V hybrid vehicles, which offer excellent fuel efficiency at relatively affordable costs, is expected to increase, especially in Europe. Mitsubishi Electric developed its ISG system-a crankshaft direct-driven system for idling-stop-start, energy recovery and torque assist-to achieve higher output power and better fuel efficiency in 48V hybrid vehicles.
