Optimization of Series Hybrid Electric Vehicle Operational Parameters By Simulated Annealing Algorithm

Aimed at solving the more and more serious problems of energy and pollution, hybrid electric vehicle (HEV) is one of the best practical applications for transportation with high fuel economy and low emission. Since the extent of improvement included with HEV greatly depends on selection of the operational parameters, simulated annealing (SA) algorithm is introduced to optimize the operational parameters for fuel economy and emissions in this paper. Compared with one of the widest used strategies, dividing rectangles (DIRECT), the computation procedure of simulated annealing algorithm are discussed, and simulation study based on the model of series hybrid electric vehicle is given to illustrate the optimization feasibility of the simulated annealing algorithm.
