Abstract

Embodiments of the invention provide a voltage output method for a charger and the charger, and relate to the technical field of communications. The method comprises the steps of detecting whether the output end of the charger is connected with an external device or not when the charger is connected with a power supply; when the output end is not connected with the external device, determining that the charger is in a no-load state; detecting whether a power pin voltage of the output end exceeds a preset voltage threshold or not, wherein the voltage threshold is a maximum voltage value corresponding to the no-load state; and if the power pin voltage exceeds the voltage threshold, reducing the power pin voltage or turning off a voltage output to a power pin. According to the method and the charger provided by the embodiments of the invention, the output end of the charger in the no-load state is provided with a low voltage or is not electrified, so that the purpose of reducing an electrolytic corrosion situation of the charger in the no-load state is achieved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a voltage output method of a charger and a charger. Background technique [0002] With the development of mobile communication technology, mobile terminals such as mobile phones, tablet computers, and personal digital assistants are becoming more and more popular, bringing great convenience to people's life, study, and work. [0003] These mobile terminals are usually configured with a Universal Serial Bus (Universal Serial Bus, USB) interface, so as to use a UDB data line for data transmission and / or charging. When charging the mobile terminal, the charger is plugged into a socket connected to a power supply, and connected to the mobile terminal through a UDB data cable. [0004] In order to facilitate the user to charge the mobile terminal at any time, the charger is usually plugged into a socket connected to a power supply such as commercial power, so that the output e...
