The invention discloses a method and system for displaying the remaining driving range of an electric vehicle and the vehicle. The method comprises the steps that the normal-temperature energy consumption and the normal-temperature driving range of the electric vehicle are obtained; based on the real-time environment temperature and the first fitting curve, a real-time temperature correction coefficient corresponding to the electric vehicle is obtained; obtaining a real-time health degree correction coefficient corresponding to the electric vehicle based on the real-time driving mileage and the second fitting curve; acquiring a second battery discharge capacity and a second driving mileage of the electric vehicle within a preset time range before the current moment, and calculating an energy consumption correction coefficient corresponding to the electric vehicle based on the second battery discharge capacity, the second driving mileage and the normal-temperature energy consumption; based on the SOC information, the normal-temperature driving mileage, the real-time temperature correction coefficient, the real-time health degree correction coefficient and the energy consumption correction coefficient, the remaining driving mileage of the electric vehicle is calculated; and controlling an instrument of the electric automobile to display the remaining driving mileage in real time. The display accuracy of the remaining driving range of the electric vehicle is effectively improved.
