British company Controlled Power Technologies (CPT) has announced the development of a belt-driven Integrated Starter Generator (B-ISG) that provides stop-start functionality. CPT claims that it suited for both gasoline and diesel engines, up to 3 and 2.5 liters respectively. CPT's SpeedStart device uses a liquid cooled switched reluctance (SR) electrical machine, coupled to power electronics, and is contained in a single housing. The unit is sold as a "very robust production-ready plug-and-play
Controlled Power Technology's Variable Torque Enhancement System (VTES) is currently being shown off in Stuttgart, Germany. According to Guy Morris, engineering director and chief technical officer, "From an idea first conceived in the year 2000, this technology has been progressively developed to the point where it is now a mature well-proven second-generation design, ready to be adopted by carmakers."
