The invention belongs to the technical field of new energy vehicles, and particularly relates to a vehicle battery thermal runaway early warning method, a vehicle battery thermal runaway early warning device, a computer readable medium and electronic equipment. The vehicle battery thermal runaway early warning method comprises the steps of obtaining real-time battery data of a current vehicle, wherein the real-time battery data comprises one or more state parameters used for representing the real-time running state of a battery; counting the battery state change rate of the current vehicle in a specified time interval according to the real-time battery data, wherein the battery state change rate is used for representing the average change quantity of state parameters of the battery corresponding to unit time in the specified time interval; and according to the battery state change rate and an early warning threshold value, predicting a future time node when the battery thermal runaway of the current vehicle occurs, wherein the early warning threshold value is a threshold value dynamically updated according to historical battery data of a historical vehicle with the battery thermal runaway occurring. The battery safety of the vehicle can be improved.
