The invention provides a lithium battery thermal runaway prevention and control system and method and a storage medium, and relates to the technical field of electric vehicle safe driving. The prevention and control system for lithium battery thermal runaway comprises a data monitoring device, a temperature transmitting device, an automatic fire extinguishing device and an automatic early warning system, the data monitoring device is used for collecting and detecting the temperature in the storage battery cabin and sending a corresponding temperature variable to the temperature transmitting device; the temperature transmitting device is used for converting the temperature variable into a standardized output signal and then transmitting the standardized output signal to the automatic early warning system; the automatic early warning system is used for judging whether an early warning state is started or not according to the standardized output signal and sending out an automatic starting signal in the early warning state so as to control the automatic fire extinguishing device to extinguish fire of the storage battery cabin. According to the technical scheme, the temperature of the storage battery cabin can be monitored in real time, fire behavior can be accurately recognized, and automatic fire extinguishing can be carried out.
