Abstract: The hybrid ratio of a parallel hybrid electric vehicle (PHEV) and its energy management strategy are analysed. On the basis of the drivetrain configuration of the CFA6470 parallel hybrid electric vehicle (CFA6470PHEV), the energy management system of the CFA6470PHEV is designed. The optimisation of the engine throttle angle and vehicle shift, along with the mild hybrid and full hybrid strategy are also studied. An energy balance method is introduced to estimate the state of charge for the battery pack. The energy management system is simulated with the experimental data of the engine and ECE-EUDC cycles. Simulation results indicate that the energy management system is feasible and achieve the anticipated goal.
