Fan speed regulation method and device, equipment and storage medium

The invention discloses a fan speed regulation method, device and equipment and a storage medium, and the method comprises the following steps: carrying out temperature partitioning on battery modules in a battery cluster to obtain at least two cluster temperature regions, the battery cluster comprising a plurality of battery modules; obtaining linear adjustment models and input temperature values corresponding to the cluster temperature regions, wherein the linear adjustment models are in one-to-one correspondence with the cluster temperature regions; inputting the input temperature value into a linear adjustment model corresponding to the cluster temperature region to obtain a fan target duty ratio corresponding to the battery module in the cluster temperature region; and the actual duty ratio of the fan corresponding to at least one battery module in the cluster temperature area is obtained, and the actual duty ratio of the fan is adjusted to be the target duty ratio of the fan. According to the method, th
