The invention relates to a battery thermal runaway early warning method and device and a storage medium, and the method comprises the steps: detecting an air pressure abnormal signal transmitted by an air pressure sensor; wherein the air pressure sensor is arranged in a battery pack and is used for detecting the air pressure state in the battery pack; when the air pressure abnormal signal is detected, judging whether an air pressure value generated by the air pressure sensor is effective or not; if yes, the air pressure value sent by the air pressure sensor is continuously obtained, and the change trend of the air pressure value is determined according to the continuously obtained air pressure value; and generating thermal runaway early warning information of the battery according to the change trend of the air pressure value and battery information. According to the invention, the problems of high false alarm rate and low accuracy of a battery thermal runaway early warning method in the related technology are solved.
