Control method and device for preventing power shortage of storage battery and vehicle

The invention discloses a control method and device for preventing power shortage of a storage battery and a vehicle, and relates to the technical field of electric automobiles, the control method comprises the steps that the descent rate of electric energy parameters of a first storage battery within a preset time interval is obtained, and the electric energy parameters comprise electric quantity parameters; when the electric quantity parameter is greater than or equal to a first preset threshold value, comparing the relationship between the descent rate and the first rate, and when the descent rate is greater than the first rate, controlling to close the first power consumption equipment; when the electric quantity parameter is smaller than a first preset threshold value and larger than or equal to a second preset threshold value, the relationship between the descent rate and a second rate is compared, and when the descent rate is larger than the second rate, the second power consumption device is controlle
