Abstract

The invention provides a charging device and a charging method. The method comprises the steps of acquiring a target battery voltage of electronic equipment under the condition that electrical connection of the electronic equipment and a charging contact of the charging device is detected; acquiring a charging voltage matched with the target battery voltage, wherein the charging voltage is largerthan or equal to the target battery voltage, and the difference between the charging voltage and the target battery voltage does not exceed a preset threshold; and adjusting an output voltage of the charging device as the charging voltage by a voltage control unit, and charging the electronic equipment. Compared with a mode of fixing an output voltage in the prior art, the charging method providedby the invention has the advantages that waste of the output voltage can be reduced, the electric energy conversion efficiency of the charging device is improved, and the charging frequency of the charging device on the electronic equipment is further increased.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a charging device and a charging method. Background technique [0002] With the rapid development of electronic technology, the application of electronic devices has become more and more extensive, and the battery life of most electronic devices depends on the capacity of the battery. However, most of the current electronic devices have a small battery capacity due to volume limitations, and users need to charge the electronic devices frequently. [0003] Take wireless earphones as an example. Due to the limited size of current wireless earphones, the built-in battery is generally very small. Therefore, it will be equipped with a charging device (such as a charging box) to facilitate charging. In order to make the charging device convenient for users to carry, its built-in battery It is not very large, resulting in a limited number of times that can be used to charge wir...
