The invention provides a battery equalization control method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a voltage value corresponding to each battery in a battery pack, and calculating a voltage difference value between the battery with the maximum voltage and the battery with the minimum voltage in the battery pack; performing filtering processing on the voltage difference value to obtain a filtered voltage difference value; taking the filtered voltage difference value as the input of a predetermined single neuron control algorithm model, performing nonlinear processing on the filtered voltage difference value by using a neuron self-learning algorithm and a vector converter in the single neuron control algorithm model, and outputting a target voltage difference state value; and calculating equalization time and a duty ratio according to the target voltage difference state value, and based on the equalization time and the duty ratio, controlling an equalization switch in the battery management system to carry out voltage equalization until the cell voltage of the battery reaches the target voltage. The battery equalization efficiency and equalization effect can be improved while the cost is reduced, so that the battery consistency is improved, and the service life of the battery is prolonged.
