Summary

Over the coming years the hybridization of the powertrain will be a key theme in the automotive industry – and the 48 Volt electrification will be a major part of it. Continental has worked with project partners intensively on 48 Volt hybrid solutions like the Gasoline Technology Car 1 (GTC1, P0, 2014) and its follower, the GTC2 vehicle on basis of a P2 architecture.

The always remaining question 'what is beyond' has lead Continental engineers to trends like the Connected Vehicle and 48 Volt Power net. These have been scouted in a next step to explore a more comprehensive system solution exceeding the 'classical' scope of hybrids.

As a result, the presented 48 Volt P2 system demonstrates a high fuel reduction potential under different driving cycles and thermal comfort (AC) user conditions. These are enabled by connectivity, data analytics, realtime, and individualization. Connected Energy Management (cEM) paves the way to get a seamless integration
of further 48 Volt power net functions which will be presented.
