The invention relates to a power battery charging heat management method and device, computer equipment and a storage medium. The method comprises the following steps: firstly, acquiring charging data and thermal management data of a battery pack; then, a reward function of an initial charging thermal management strategy model is established based on the charging data and the thermal management data, and the initial charging thermal management strategy model is an offline reinforcement learning model; then, inputting the charging data, the heat management data and a reward function into the initial charging heat management strategy model to obtain an expected reward value, and adjusting parameters of the initial charging heat management strategy model based on the expected reward value to obtain a target charging heat management strategy model; and finally, inputting to-be-tested vehicle data into the target charging heat management strategy model to obtain a target charging heat management strategy. The charging strategy and the thermal management strategy of the whole process can be flexibly regulated and controlled according to the battery state of the whole process, so that the control effect is more accurate.
