Mitsubishi Electric has begun mass-producing the first crankshaft-mounted integrated starter-generator system for 48V hybrid systems. This system will be used by Mercedes-Benz and is on display at Tokyo Motor Show 2017.
Most hybrid systems are belt-driven, with the motor transferring power to the engine or drive shaft through belts and pulleys. These can limit maximum torque output allowances and can bleed some of the energy off. The Mitsubishi Electric integrated starter-generator (ISG) system connects directly to the crankshaft and eliminates those issues.
