Method and device for predicting cycle life of battery, and computer storage medium

The invention discloses a battery cycle life prediction method and device, and a computer storage medium, and the method comprises the steps: carrying out the first charging and discharging cycle operation of a first preset cycle number on a target battery in a determined target SOC interval, and obtaining the test capacity retention ratio of the target battery, the target SOC interval is determined by the battery parameters of the target battery, and the battery parameters of the target battery comprise the SEI membrane impedance of the target battery and the expansion force of the target battery; according to the capacity retention ratio prediction relational expression corresponding to the target battery and the test capacity retention ratio, the target capacity retention ratio of the target battery after second charge-discharge cycle operation of the first preset cycle number is predicted, and the target SOC interval is within the interval range of the SOC interval corresponding to the second charge-disch
