The invention discloses a power battery thermal runaway control method, a new energy vehicle and a storage medium. The method comprises the steps that the vehicle state is obtained; the temperature detection module is started in response to the vehicle state, so that the temperature detection module obtains the current temperature of the outer surface of the power battery in real time; when the current temperature is larger than or equal to a preset first temperature threshold value, the cooling system is controlled to input cooling liquid into the cooling channel; when the current temperature is larger than or equal to a preset second temperature threshold value, an unlocking pushing device is controlled to work so as to relieve the locking relation between the power battery and the vehicle body power battery assembling groove, and the unlocking pushing device is controlled to push out and separate the power battery from the vehicle body power battery assembling groove; wherein the second temperature threshold value is greater than the first temperature threshold value. According to the invention, the thermal runaway power battery can be cooled and separated, the property loss is reduced, and the personnel safety is improved.
