Resumen:
Hybrid electric vehicles (HEV) present several advantages over conventional mobility platforms. Inorder to maximize the benets of incorporating a hybrid transmission an adequate energy manage-ment strategy (EMS) is required. The later sets the operating condition of both the propulsionsystem and the internal combustion engine (ICE) given the operational state of each component andthe driving requirements set by the driver. The EMS main objective is to maximize the overall effi-ciency of the vehicle; however, other indicators like tailpipe emissions and component deteriorationhave to be taken into account when establishing the optimum EMS. This paper assesses two onlineEMS applied to a hybrid electric bus (HEB). Specically, the Load Following Strategy (LFS) andthe Equivalent Consumption Minimization Strategy (ECMS) are evaluated performing a parametricsweep. In order to establish the driving conditions to which the bus will be subjected to, a BuenosAires urban bus driving cycle (BADC) based on GPS data is presented. A model of the HEB isdeveloped using maps and low order models to establish efficiency and dynamics of the differentsubsystems involved. Furthermore, a dedicated model to quantify the battery deterioration is im-plemented. Results show that using either strategy a considerable reduction on battery stress canbe achieved at expense of a relatively low fuel consumption increase. The best fuel performance isobtained with the LFS while the lower battery deterioration is performed by the ECMS. Results arevalidated using Autonomie and compared with the optimal solution obtained from the deterministicdynamic programming
