The invention discloses a method and a related device for determining generated power of an extended-range mine truck, and relates to the field of extended-range mine trucks, and the method comprises the steps: predicting target vehicle demand power in a second time domain length in the future based on historical vehicle demand power in a first time domain length before a current moment, and determining a target equivalent factor by adopting a dichotomy based on the target vehicle demand power and an equivalent consumption minimization strategy, so that the actual SOC of the power battery at the end moment of the predicted time domain after the current moment converges to the theoretical SOC of the power battery, and determining the actual SOC of the power battery based on the target equivalent factor and the actual vehicle demand power. And determining the target generated power of the extended-range mine truck by adopting an equivalent consumption minimization strategy. According to the method, the target equivalent factor that the actual SOC of the power battery converges to the theoretical SOC of the power battery is determined according to the predicted target vehicle demand power in combination with the equivalent consumption minimization strategy, and the target generated power meeting the actual operation condition of the extended-range mine truck is obtained according to the target equivalent factor and the actual vehicle demand power.
