HEVs Comparison and Components Sizing Using Dynamic Programming

This paper presents a backward approach for HEVs modelling with a global optimization method. This method allows to determine the maximal potential gain in terms of CO2 emission for a given HEV. It is then applied to size and compare two hybrid architectures and conventional vehicles. Finally a comparison on measurement, classical forward approach and optimized backward approach is performed on the Toyota Prius 2004 vehicle.
