The invention provides a battery detection method, a prediction model training method and related equipment, and the method comprises the steps: obtaining the parameter information of a battery of a vehicle in a current time period, and the parameter information comprises the voltage, current, temperature and resistance of the battery; determining each first index value corresponding to the current time period according to the parameter information, and performing preset operation processing on the first index values of the same type to obtain each second index value; and inputting each first index value and each second index value into a prediction model, and determining whether the battery has a thermal runaway risk or not according to output information of the prediction model. In the application, the first index values including the mean value, the variance, the extreme value, the kurtosis and the skewness are determined through the temperature, the voltage, the resistance and the current of the battery, and the second index values are derived based on the first index values, that is, the thermal runaway of the battery is predicted through various parameters, so that the detection accuracy of the thermal runaway of the battery is improved.
