In this study, two fuel‐cell hybrid systems for the energy performance comparison of fuel‐cell hybrid vehicles (FCHVs) are presented. A Matlab/Simulink modelwas constructed, and the main power source was a fuel cell. A lithium battery and a flywheel battery were the auxiliary power sources. A vehicle driving test, FTP‐75 (Federal Test Procedure), was applied for four different control modes:mixed common output mode, normal driving charge mode, fuel‐cell mode, and braking mode. FTP‐75 simulated the energy requirements and energy output stateof the full‐motor hybrid system. The results show that the recovered energy of the flywheel battery was higher than that of the lithium battery, and the output power was close to the motor output curve. The flywheel battery can withstand rapid charging and discharging, which substantially reduces time and instantaneous motor current output. It can also effectively reduce the load on the motor. Finally, the flywheel battery enhanced the driving range of the hybrid vehicle to a greater degree than the lithium battery did under the same conditions. The overall energy consumption is reduced by 22.7%; corresponding to a hydrogen saving of 17.8 g.
