Automobile storage battery voltage prediction model training method, voltage prediction method and device

The invention relates to an automobile storage battery voltage prediction model training method and device, a voltage prediction method and device, equipment and a medium. The method comprises the following steps: acquiring multiple pieces of time sequence data of a sample automobile corresponding to a first time interval, and inputting the multiple pieces of time sequence data into a to-be-trained automobile storage battery voltage prediction model to obtain time sequence features corresponding to the time sequence data; obtaining a feature weight corresponding to each time sequence feature through an attention mechanism, and obtaining a predicted storage battery voltage signal, corresponding to the second time interval, of the sample automobile according to each time sequence feature and the feature weight; and according to the difference between the actual storage battery voltage signal of the sample automobile and the actual storage battery voltage signal of the sample automobile corresponding to the seco
