Open-circuit voltage prediction method and device, electronic equipment and storage medium

The invention provides an open-circuit voltage prediction method and device, electronic equipment and a storage medium. Relates to the technical field of batteries, and the open-circuit voltage prediction method comprises the steps that under the condition that a to-be-detected battery is in a standing state, characteristic parameters of the to-be-detected battery at each moment under a preset sampling frequency are acquired, and the characteristic parameters comprise sampling voltage, sampling time and a battery state before standing; based on the sampling voltage, the sampling time and a preset parameter model, an open-circuit voltage prediction model is determined, and the preset parameter model is used for obtaining model parameters of the open-circuit voltage prediction model according to the sampling voltage and the sampling time so as to determine the open-circuit voltage prediction model; and according to the sampling time, the open-circuit voltage prediction model and the battery state before standin
