摘  要:
A real-valued genetic optimization algorithm is proposed to improve fuel economy for a plug-in HEV using hybrid energy storage system during SOC sustaining phase. The optimization algorithm is developed based on the objective function of minimizing fuel consumption, and the optimal operation torque of engine, the optimal split coefficient for battery current, the maximum velocity in pure electric mode, and the upper / low limits of battery SOC can be achieved. The simulation results showed that fuel economy of the plug-in HEV can be increased while sustaining battery SOC, and charge / discharge performance and life cycle of battery can also be improved.
