ENERGY MANAGEMENT STRATEGIES FOR VEHICULAR ELECTRIC POWER SYSTEMS

In this paper, the authors examine hybrid electric vehicle (HEV) energy management strategies for controlling the vehicular electric power system. In order to reduce fuel use and emissions, the authors propose generating and storing electrical energy only at the most suitable moments. This is done by developing and testing off-line optimization methods using knowledge of driving patterns and on-line implementation in a simulation environment. Results show that even without a prediction of the driving cycle being used, a reduction of 2 percent in fuel use is seen, as well as even larger reductions of emissions. The authors relate that their strategies are also applicable to a mild HEV with an integrated starter alternator (ISA), without any modifications, as well as to other types of HEVs with small modifications to the formulation.
