The invention provides a temperature correction method, device and equipment of a power battery and a storage medium, relates to the technical field of battery optimization control, and is used for correcting the battery cell temperature output by a temperature sensor, so that the battery cell temperature is closer to the real battery cell temperature, and the driving safety of a vehicle is guaranteed. The method comprises the steps of determining that a current scene meets a correction scene condition of a power battery according to driving parameters of the hybrid vehicle; according to the first battery cell temperature of the first type of battery module and the second battery cell temperature of the second type of battery module except the first type of battery module, which are output by the temperature sensor, the degree of influence of the engine thermal radiation on the first battery cell temperature is greater than a preset threshold value, a correction starting condition meeting the first type of battery module is determined; and determining a temperature correction reference value of the first type of battery module according to the second battery cell temperature, determining a temperature correction target value of the first type of battery module by combining the first battery cell temperature, and correcting the first battery cell temperature output by the temperature sensor according to the determined temperature correction target value.
