The embodiment of the invention provides a battery thermal runaway detection method and device, a battery management system, a vehicle and a storage medium. The battery thermal runaway detection method comprises the steps of obtaining temperature information of a battery; according to the temperature information, determining whether the temperature change of the battery in a preset time period conforms to a preset thermal runaway temperature early warning curve or not; and if the temperature change conforms to the thermal runaway temperature early warning curve and the maximum temperature value in the preset time period is greater than or equal to a preset value, sending early warning information. According to the battery thermal runaway detection method provided by the embodiment of the invention, early warning can be carried out on thermal runaway of the battery in advance, and enough escape time of a user is ensured.
