CHARGING METHOD AND CHARGING DEVICE

A charging method includes: charging a battery according to a second current value after charging the battery according to a first current value in each of N charging cycles, the second current value being less than the first current value, and N being a positive integer; and charging the battery according to a target cutoff voltage value in the case where a target voltage value is greater than or equal to the target cutoff voltage value at the end of the N charging cycle. The target voltage value is a charging voltage value corresponding to the first current value, and the target cutoff voltage value is a first cutoff voltage value, or the target voltage value is a charging voltage value corresponding to the second current value, the target cutoff voltage value is a second cutoff voltage value.
