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.
