CPT developing 48-volt electric supercharger for micro-mild hybrids

Green Car Congress

At 48 volts, a VTES electric supercharger will transform 7kW of battery power into a highly boosted charge of air for downsized gasoline and diesel engines. There will be no torque deficit or other tradeoffs from essential engine downsizing and higher gearing, which now dominates the development of internal combustion engines.

Magnetic eCVT could replace conventional hybrid mechanical eCVT with likely 1-2% fuel economy improvement and other benefits

Green Car Congress

Magnomatics has created three prototypes based on the specification of a 200 N·m C-Class passenger car: the original MAGSPLIT 1 with three rotors; MAGSPLIT 2a with surface mount magnets, running about the same magnet grade as the original MAGSPLIT; and MAGSPLIT 2b with interior magnets (magnets embedded within the rotor.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

In fact, the optimized PHEV is much more efficient as a long range liquid fuel vehicle, because the engine is downsized. The positive results including costs, need to be properly published and distributed, creating and accelerating the demand for all classes of PHEVs from small cars to full-size trucks and buses.
