Title:
METHOD AND APPARATUS FOR OBTAINING POWER BATTERY LIFE DATA, COMPUTER DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/208079
Kind Code:
A1
Abstract:
A method and apparatus for obtaining power battery life data, a computer device, and a medium. A planned number of discharge-charge cycles of a target power battery is obtained; then the planned number of discharge-charge cycles is put into a pre-built power battery life data regression model; the power battery life data regression model is obtained by performing model building on the basis of an accelerated aging data set of a sample power battery, a target power battery capacity data set can be used for describing life data of the target power battery, a target confidence interval is used as a reference probability of the target power battery capacity data set and describes uncertainty of the target power battery capacity data set, and therefore, the power battery life data regression model can output a corresponding target power battery capacity data set and a target confidence interval according to the planned number of discharge-charge cycles. Thus, the problem that power battery life data cannot be obtained is solved.
