Intelligent power management of plug-in hybrid electric vehicles, part II: real-time route based power management

PHEVs are considered as a viable solution to address environmental concerns facing the global automotive industry. In this paper, we design a new real–time route–based power management system for PHEVs based on the adaptive equivalent consumption minimisation strategy (A–ECMS). The designed controller takes advantage of preview trip information to achieve even higher efficiencies. To evaluate the designed system, this controller was assigned to a high fidelity model of Toyota Prius Plug–in Hybrid built in Autonomie. The results are compared against those of several existing power management systems, including: charge depleting charge sustaining (CDCS), manual CDCS, and rule–based strategies as well as Pontryagin's minimum principle (PMP). While PMP efficiency is slightly higher than the new controller, the real–time power management system proved more reliable in terms of the computational time. It is shown that route based power management strategy improved the fuel economy up to 11% compared to the rule–based controller within Autonomie.
