Technical challenge of hybrid and plug-in hybrid vehicles

Electrifying the propulsion systems of vehicles provides a number of functions that can help reduce energy consumption. This is achieved by optimizing the operating conditions of the internal combustion engine and by recovering a variable fraction of the available energy during braking,in hybrids that we will never be connected to the grid. The simplest systems,which make it possible to eliminate idling,yield fuel savings of 5 to 7% in the standardized European cycle. The most complex systems,which provide more functions,lead to savings of up to 40% in urban conditions. Electrification also allows the creation of additional functions,of benefit to the users of the vehicle or to the community,such as all-electric range and connection to the grid for plug-in hybrids. The implementation of these functions will require the addition of electric machine(s) that will be coupled to the engine in various architectures - series,parallel,series-parallel,through the road... We will briefly describe in the presentation these architectures,their specificities,together with their potential and drawbacks for the case of light duty vehicles applications.
