The invention discloses an endurance mileage estimation method and device. The method comprises the following steps: acquiring a first driving path, residual energy and real-time driving behavior data of a vehicle; performing driving style identification on the real-time driving behavior data to obtain a real-time driving style, and predicting a vehicle operation condition of the vehicle according to the first driving path and the real-time driving style; the vehicle mirror image model is controlled to run under the vehicle running working condition, and predicted energy consumption is determined; the vehicle mirror image model is constructed according to a digital twin algorithm; determining target energy consumption according to the predicted energy consumption and the historical average energy consumption; and estimating the endurance mileage of the vehicle according to the residual energy and the target energy consumption. According to the method, the predicted energy consumption obtained through the digital twin technology is combined with the historical average energy consumption obtained through the historical data of the vehicle, the target energy consumption is determined, and the endurance mileage can be estimated more accurately according to the target energy consumption.
