The invention relates to a battery temperature rise fault diagnosis method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining a temperature value set of a plurality of periods, the temperature value set comprises the temperature value of each collection position in the same period, processing the temperature value sets of adjacent periods, and obtaining the temperature value of each collection position in the same period; the method comprises the steps of obtaining a temperature difference value set corresponding to adjacent periods, sorting each temperature difference value based on a collection position corresponding to each temperature difference value in the temperature difference value set, obtaining an accumulated time length when the temperature difference value corresponding to the collection position continuously reaches a preset temperature difference threshold value based on a sorting result, and obtaining a temperature difference value corresponding to the collection position based on the accumulated time length. According to the method and the device, the problem that whether the temperature rise fault exists in the power battery or not cannot be accurately judged is solved, and the situation that the battery management system fails to report or misreports the temperature rise fault is effectively avoided, so that irreversible damage to the power battery is prevented.
