Abstract

The embodiment of the invention discloses a charging method and a charging device, which relate to the technical field of communication, so as to solve the problem of long charging time of a battery.The charging method comprises: after charging the battery according to a first current value, charging the battery according to a second current value, the second current value being smaller than thefirst current value, and N being a positive integer in each of N charging cycles; Charging the battery according to the target cutoff voltage value when the target voltage value is greater than or equal to the target cutoff voltage value at the end of each charging cycle; Wherein 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, and the target cutoff voltage value is a second cutoff voltage value, and the second cutoff voltage value is smaller than the first cutoff voltage value. The method can be applied to the scenario of charging the battery.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a charging method and a charging device. Background technique [0002] With the continuous advancement of science and technology, people rely more and more on terminals. [0003] Currently, battery charging for a terminal may generally include a constant current charging phase and a constant voltage charging phase after the constant current charging phase. Specifically: in the constant current charging phase, the battery can be charged with a constant current; in the constant voltage charging phase, the battery can be charged with a constant voltage. [0004] However, due to the polarization of the terminal battery during the constant current charging phase, charging the battery at a constant current for a long time will cause the battery impedance to accumulate continuously, so after entering the constant voltage charging phase, it may be nec...
