Lithium battery charge state prediction method, apparatus and device, and storage medium

The invention relates to the technical field of lithium batteries, and discloses a lithium battery state-of-charge prediction method, device and equipment and a storage medium, and the method comprises the steps: determining an actual capacity value of a target battery through a particle filtering algorithm, obtaining a state-of-charge prediction value of the target battery based on the actual capacity value through a state-of-charge prediction model, the method comprises the steps of obtaining an initial charge state actual value of a target battery, calculating a difference value between a charge state predicted value and the initial charge state actual value, taking the calculated difference value as input of a preset residual model to obtain a residual estimated value, and determining a current charge state value of the target battery according to the residual estimated value and the charge state predicted value. According to the method, the actual capacity value is calculated by adopting the particle fil
