Abstract:
In this paper, an energy management strategy (EMS) for a specific multi hybrid plug-in electric bus is designed.
This bus is equipped with an internal combustion engine, a hydraulic motor, an electric motor and battery.
Considering the physical characteristics of the studied hybrid electric bus (i.e., the system dynamics and the
power sources limits), an optimal control technique based on Pontryagin’s minimum principle (PMP) is used in
order to ensure that the bus achieve a significant improvement in energy efficiency. Furthermore, information
of traffic conditions obtained from intelligent transportation systems is used to further optimize the energy
management strategy and to accurately control the battery depleting rate. The work proposed in this paper is
conducted on a dedicated high-fidelity model of the hybrid bus, that was developed on MATLAB/TruckMaker
software. The obtained results verify the effectiveness and validity of the developed energy management
strategy.
