The invention discloses a range extender power generation control method and device for engineering machinery, and the method comprises the steps: selecting a range extender working point according to the bus voltage of a whole machine and a preset range extender power generation efficiency map, and carrying out the linear interpolation according to the preset map if a current voltage platform does not correspond to the preset power generation efficiency map, and correcting the power generation efficiency of the current voltage platform. Presetting basic power generation power and basic operation intensity according to the whole machine operation working condition; and obtaining the whole machine operation intensity in a preset time period, calculating a deviation value with the basic operation intensity, and correcting the generated power by taking the deviation value as a correction value of the basic generated power. The problem that the range extender adapts to different complete machine voltage platforms is solved, meanwhile, the problems that the range extender adapts to the engineering machinery operation working condition is complex, and the operation load change is large are solved, the power generation efficiency and the power generation precision are improved, and the complete machine energy consumption is further reduced.

    本发明公开了一种工程机械用增程器发电控制方法及装置,根据整机母线电压及预设的增程器发电效率map,选择增程器工作点,若当前电压平台与预设发电效率map不对应,则根据预设map进行线性插值,修正当前电压平台发电效率。根据整机作业工况,预设基础发电功率和基础作业强度;获取预设时长内整机作业强度,计算与基础作业强度的偏差值,将偏差值作为基础发电功率的修正值,对发电功率进行修正。解决了增程器适配不同整机电压平台的问题,同时解决了增程器适应工程机械作业工况复杂且作业负载变化大的问题,提高了发电效率和发电精度,整机能耗进一步降低。
