The invention provides a hybrid power system, a vehicle-mounted pump and a control method of the hybrid power system. The hybrid power system comprises an engine, a clutch, an operation motor, an upper motor controller, a rectification distribution box, a hydraulic system and an upper whole vehicle controller. The top-mounted vehicle control unit comprises a plug-in pumping mode control module which is used for sending a plug-in loop conduction request to the rectification distribution box if the rectification distribution box is externally connected with a power supply under the condition that the working mode request instruction is a plug-in pumping mode request instruction; under the condition that a plug-in circuit of the rectification distribution box is conducted, monitoring a first electric control bus voltage in the plug-in circuit, and if the first electric control bus voltage is greater than or equal to a preset first voltage threshold after a first preset time threshold and the power of the external power supply is smaller than a preset power threshold, switching on the rectification distribution box; and the engine and an external power supply are controlled to supply energy to the hydraulic system through the operation motor. And the condition that the power of an external power supply is insufficient in an electric plugging pumping mode can be well compensated.

    本发明提供一种混合动力系统、车载泵及混合动力系统的控制方法,混合动力系统包括:发动机、离合器、作业电机、上装电机控制器、整流配电箱、液压系统和上装整车控制器;上装整车控制器包括:插电泵送模式控制模块,用于在工作模式请求指令为插电泵送模式请求指令的情况下,若整流配电箱已外接电源,则向整流配电箱发送插电回路导通请求;在整流配电箱的插电回路导通的情况下,监测插电回路中的第一电控母线电压,若在第一预设时间阈值之后,第一电控母线电压大于或等于预设的第一电压阈值,且外接电源的功率小于预设的功率阈值,则控制发动机和外接电源通过作业电机为液压系统供能。能够较好地弥补插电泵送模式下外接电源功率不足的情况。
