摘要：AbstractIn this paper, the optimization problem of energy management for a parallel hybrid electric vehicle equipped with a Step-Up converter is resolved analytically using Pontryagin’s Maximum Principle (PMP). The analytical method is based on convex models, which are identified from the reference models. A numerical method based on the reference models is also used in order to validate the analytical method by comparing their results. In this work, two optimization variables are considered: the power split between the Internal Combustion Engine (ICE) and the Electric Machine (EM) and the output voltage of the booster. The simulation results show that the analytical approach reduces considerably the computing time and has an very low suboptimality comparing to the numerical method.
