The invention relates to a hybrid power driving system and method of a loader and the loader, the hybrid power driving system comprises an engine, an ISG motor, a steering pump, a battery pack, a walking motor, a working hydraulic motor and a complete machine controller, the engine, the ISG motor and the steering pump are sequentially in transmission connection, and the ISG motor, the walking motor and the working hydraulic motor are respectively connected with the battery pack through the complete machine controller. The engine and the steering pump are respectively connected with the whole machine controller, and the walking motor and the working hydraulic motor are further respectively connected with the ISG motor. The complete machine controller judges whether the power required by the walking system, the working hydraulic system and the steering system can be met or not according to the obtained output power requirements of the walking system, the working hydraulic system and the steering system and the SOC value of the battery pack, so as to control the output power of the ISG motor and/or the battery pack; the walking system, the working hydraulic system and the steering system are coordinated to work, the energy utilization rate is increased, and the purposes of saving energy and reducing consumption are achieved.

    一种装载机的混合动力驱动系统、方法及装载机,包括发动机、ISG电机、转向泵、电池组、行走电机、工作液压电机、整机控制器,所述发动机、ISG电机和转向泵依次传动连接,所述ISG电机、行走电机、工作液压电机分别通过整机控制器与电池组连接,所述发动机、转向泵分别与整机控制器连接,所述行走电机、工作液压电机还分别与ISG电机连接。所述整机控制器根据获取到的行走系统、工作液压系统和转向系统输出的功率需求及电池组SOC值,判断行走系统、工作液压系统和转向系统所需功率是否能被满足,从而控制ISG电机和/或电池组输出功率,进而协调行走系统、工作液压系统、转向系统工作,提高能源利用率,达到节能降耗的目的。
