Abstract
The global automobile industry is rapidly changing towards zero impact mobility with regards to CO2 and Emission. The Indian regulatory provides a clear direction with regards to emission requirements and the key technologies that need to be considered. One key topic for development of conventional powertrains is linked to the Real Drive Emission regulatory that limits NOX and particulates even in cold conditions, hence the efforts for the exhaust after treatment will rise significantly. This paper will provide a possible synergetic pathway of today’s conventional technology and electrified powertrains for the Indian market. Starting with an overview on state of the Art solutions for CO2 reduction and NOX improvement for diesel engines. The results of a 48V PHEV with a gasoline engine and an electric axle with 20kW will be illustrated, the limitations highlighted and the system synthesis for a novel scalable 48V solution, enabling higher transient power will be discussed. The new 48V high power topology enables affordable zero emission in inner cities for small to medium size vehicles. The outlook on modularity and boundaries of such a system from 48V MHEV, PHEV up to BEV will be given.
