The invention relates to the related technical field of engineering machinery, in particular to a hybrid power system of a crane and a control method. The power system comprises a fuel oil power subsystem and an electric power subsystem which are connected in parallel, and the two sets of power subsystems can provide power for a crane operation assembly. The fuel oil power subsystem is connected with a first operation assembly of the crane and used for providing power for the operation assembly of the crane in a first operation working condition, and the electric power subsystem is connected with a second operation assembly of the crane and used for providing power for the operation assembly of the crane in a second operation working condition. Thus, fuel oil consumption, emission and pollution are reduced by reducing the working condition of fuel oil energy supply, the requirement for the electric capacity of a battery is not high due to the fact that only power for part of the working condition needs to be provided through electric power, and the small-capacity battery can be used, so that the electricity utilization safety of engineering machinery is guaranteed, and cost is saved.
本申请涉及工程机械相关技术领域,具体涉及一种工起重机混合动力系统和控制方法。该动力系统包括并联的燃油动力子系统和电动力子系统,两套动力子系统均能为起重机作业组件提供动力。燃油动力子系统通过与起重机第一作业组件连接,用于在第一作业工况中为起重机作业组件提供动力,电动力子系统与起重机第二作业组件连接,用于在第二作业工况中为起重机作业组件提供动力。如此,通过减少燃油供能的工况,实现减少燃油消耗,降低排放和污染,而且因为只需要通过电力提供一部分作业工况的动力,所以对电池电容量要求并不高,可以使用小容量的电池,从而保证工程机械用电安全,以及节省成本。
