The invention relates to the technical field of automobiles, and discloses a vehicle energy consumption prediction method, system and equipment, and the method comprises the steps: obtaining the route information, vehicle position information and average energy consumption information of a vehicle, predicting and recording the energy consumption of the vehicle at an energy consumption calibration road section according to the obtained information and an initial energy consumption prediction model, and if a difference value between the first energy consumption information and the actual energy consumption information is greater than a preset threshold value, iteratively updating parameters of the initial energy consumption prediction model according to the difference value until a target energy consumption prediction model meeting a preset condition is obtained, and finally, predicting the energy consumption of the road section to be driven according to the target energy consumption prediction model to obtain second energy consumption information, and generating energy consumption prompt information according to the second energy consumption information. According to the technical scheme, the energy consumption of the pure electric vehicle can be predicted and updated, and the problem that the difference between the predicted energy consumption and the actual energy consumption is large when the energy consumption of the vehicle is predicted is solved.
