Abstract: Power-split hybrid electric vehicles (PS-HEV) are the most efficient solution to reduce fuel consumption using electric hybridisation of vehicles. However, different architectures exist or can be developed and it is difficult to perform a fair comparison between these solutions. A global design approach, optimising the size of the components and using optimal energy management can be a good way to compare different PS-HEV architectures. This paper presents a method to size and design HEV in an optimal manner and to compare this vehicle on different objectives: fuel consumption, battery size, and global volume of the system. The method is then applied to four SP-HEV based on existing architectures (Toyota Hybrid System, Opel Ampera) and on alternative solutions (electrical variable transmission and serial-parallel architecture).
