42V System for Future Passenger Cars 2001-28-0019

Fuel economy and emission reduction assume significant importance for automotive research activities and conversion of many mechanical / hydraulic loads to electrical loads helps in realizing this objective. As a result, many electrical power hungry loads are anticipated to be introduced soon in global market with average power requirement exceeding the practical limit of the present automotive electrical system implying the necessity of a suitable higher voltage system. Many OE and component manufacturers have come to a consensus to choose 42V as the system voltage for future passenger cars considering various aspects. This paper highlights the advantages of the high voltage system together with some of the issues associated with the new system.
