The invention provides a power control method for a hybrid power system, and the hybrid power system. According to the control method, the target power of the generator is determined by considering the efficiency value and the equivalent oil consumption value of the power generation system comprising the engine and the first motor, so that the generator is controlled to generate the actual power of the generator based on the target power of the generator; a driving power for driving the vehicle and a charge-discharge state of the battery are allocated based on a magnitude relationship betweenthe generator actual power and the requested driving power. Thus, according to the method, a special engine and a high-efficiency battery energy conversion technology are not needed, the energy generation mode and the energy use mode can be optimized in a mode of not increasing the cost, and then the relation between energy generation and energy use of the series hybrid power system is optimized.
本发明提供了一种混合动力系统用功率控制方法及混合动力系统。在该控制方法中,通过兼顾包括发动机和第一电机的发电系统的效率值和等效油耗值两方面确定发电机目标功率,从而基于该发电机目标功率控制发电机产生发电机实际功率,基于发电机实际功率与请求驱动功率之间的大小关系来分配用于驱动车辆的驱动功率和电池的充放电状态。这样,上述方案不需要专用的发动机和高效率的电池能量转换技术,能够以不增加成本方式优化能量产生方式和能量使用方式,进而优化了串联式混合动力系统的能量产生和能量使用之间的关系。
