Abstract
A method for predicting a life includes the following. Obtain multiple cycle numbers of a battery and multiple capacity data corresponding to the cycle numbers. Obtain multiple sets of first fitting data by fitting the cycle numbers and the capacity data with a bi-exponential empirical model. Obtain multiple sets of second fitting data by fitting the cycle numbers and the capacity data with a box-cox transformation method. Determine a first capacity error according to the multiple sets of first fitting data and the multiple capacity data. Determine a second capacity error according to the multiple sets of second fitting data and the capacity data. Generate a battery-life prediction model according to the first capacity error, the second capacity error, the multiple sets of first fitting data, and the multiple sets of second fitting data. Determine an RUL of the battery according to a predetermined battery-capacity-value and the battery-life prediction model.
