经济型燃料电池混合动力轿车控制策略研究与参数优化

In this paper, control strategy for economy fuel cell hybrid electric vehicle(FCHEV) is studied by using power-following control mode. Based on a domestic economy car configuration, simulation analysis for a refitted economy fuel cell hybrid electric vehicle is conducted by means of ADVISOR software. Fuel economy and power characteristics of the FCHEV are calculated under different degrees of hybridization in 4 typical driving conditions. Optimal match hybridization degree is obtained for the FCHEV. Under the best degree of hybridization, parameter optimization is done on final drive ratio, fuel cell maximum and minimum working power, battery charge power in order to obtain minimum hydrogen consumption. Optimal working points were achieved for FCHEV.
