The invention relates to a remaining mileage estimation method and device, a vehicle and equipment, and relates to the technical field of vehicles, and the method comprises the steps: obtaining the historical average energy consumption, navigation data and battery remaining capacity of the vehicle; the historical average energy consumption is the energy consumption per unit mileage calculated based on the historical operation information of the vehicle; the navigation data comprises road information of at least one driving road section from the current position to the target position; the road information comprises driving distance information and gradient information; the historical average energy consumption comprises motor average energy consumption and first heat management average energy consumption; determining target predicted energy consumption based on the motor predicted energy consumption and the first thermal management average energy consumption; the motor predicted energy consumption is predicted motor energy consumption per unit mileage; and calculating a predicted remaining mileage of the vehicle based on the battery remaining capacity and the target predicted energy consumption. Therefore, the remaining mileage of the vehicle can be accurately estimated by the remaining capacity of the battery.
