The invention discloses a residual driving range estimation method and device, a vehicle and a storage medium, and the method comprises the steps: obtaining the first average power consumption of the vehicle, the current residual electric quantity and the whole vehicle mass during the current residual driving range estimation, and obtaining the second average power consumption obtained during the previous residual driving range estimation; determining a weight factor according to the mass of the whole vehicle; according to the weight factor, carrying out weighted summation on the first average power consumption and second average power consumption obtained when the last residual driving range is estimated, so as to obtain second average power consumption when the residual driving range is estimated at this time; and according to the second average power consumption and the current remaining electric quantity during the current remaining driving mileage estimation, obtaining the remaining driving mileage during the current remaining driving mileage estimation so as to obtain the current remaining driving mileage. Therefore, the weight factor is determined according to the vehicle mass, weighted summation is carried out according to the weight factor to update the average power consumption, the accuracy of estimation of the remaining driving range is improved, and the method is simple.
