The invention is suitable for the technical field of automobiles, and provides a defrosting method and device of an outdoor heat exchanger, a storage medium and a vehicle. The outdoor heat exchanger is arranged in a heat pump system of the vehicle, and the defrosting method comprises the steps that whether the outdoor heat exchanger is frosted or not is detected; if it is detected that the outdoor heat exchanger is frosted, the cooling liquid temperature of a target cooling liquid loop is detected, the target cooling liquid loop is used for providing heat for a refrigerant of a heat pump system, and the refrigerant is used for defrosting the outdoor heat exchanger; if the cooling liquid temperature of the target cooling liquid loop is smaller than a first temperature threshold value, the target cooling liquid loop is controlled to store heat, and the first temperature threshold value is associated with the environment temperature of the vehicle; and if the cooling liquid temperature of the target cooling liquid loop is larger than or equal to the first temperature threshold value, the heat pump system is controlled to conduct defrosting on the outdoor heat exchanger. According to the embodiment of the invention, the defrosting effect can be improved.
