Comparative Study of Generic Hybrid Topologies

This paper presents a detailed comparison of the performance, efficiency and emissions of four different hybrid topologies. The comparison is made by simulation with all motor models, battery models, control laws etc as similar as possible between the hybrid types. The simulation model uses an ICE model where efficiency and emissions are dynamically accounted for. The impact of transient operation of the ICE in the different hybrids is thus evaluated in as fair a comparison between different topologies as possible. All modelled hybrids are equipped with ICE and electrical machines with rated power and other properties as like a Toyota Prius as possible. The comparison is made when running a US06 driving cycle.
