The invention discloses a battery pack thermal runaway protection method and device, a heat pump system and a vehicle, a battery pack exchanges heat through the heat pump system, the heat pump system comprises a fire-fighting switch arranged corresponding to the battery pack, and the method comprises the steps that when the battery pack has a thermal runaway risk or thermal runaway occurs, the fire-fighting switch is switched on or switched off; acquiring the power supply condition of the battery pack; wherein the battery pack is used for supplying power to high-voltage components in the heat pump system; and the heat pump system is controlled based on the power supply condition of the battery pack, and the fire-fighting switch is controlled to be in an on state, so that the flame-retardant refrigerant in the heat pump system is sprayed to the battery pack. According to the protection method, the battery pack can be cooled, the concentration of combustible gas is reduced, and the purpose of emergency fire fighting is achieved.
