Developing a Health-Conscious Energy Management Strategy Based on Prognostics for a Battery/Fuel Cell Hybrid Electric Vehicle

Since the degradation of energy sources in battery/fuel cell hybrid electric vehicles (HEVs) is inevitable and highly influences the durability of the system, an energy management strategy (EMS) aiming at prolonging the lifetime is demanding. In fact, the predictive nature of prognostics gives chance to develop such an EMS, which performs energy management through automatic corrective actions with the help of the awareness of energy sources' health states. This paper has addressed some scientific issues encountered when considering EMS based on prognostics and proposed an EMS based on fuzzy logic control which has successfully mitigated the battery degradation.
