The invention relates to a vehicle energy management method and device, a vehicle and a storage medium, and the method comprises the steps: obtaining the path information of a current navigation path of the vehicle, and dividing the current navigation path into a plurality of segmented paths based on the path information; the current battery electric quantity and the current electric appliance accessory operation parameters of the vehicle are obtained; according to the path information and the current electric appliance accessory operation parameters, estimating the segmented electric quantity required by the vehicle on each segmented path under the pure electric driving working condition and the total electric quantity required by the vehicle for driving to the destination; and obtaining a current range extender control strategy meeting a preset noise standard based on the segmented electric quantity, the total electric quantity, a pre-constructed vehicle speed-power generation strategy range extender driving score table and the path information, so as to perform energy management on the vehicle by using the range extender control strategy. The control strategy of the range extender can be adjusted in real time according to the road traffic information and the navigation plan, the power system noise in the vehicle driving process is reduced, and the user experience is improved.
