Abstract

An adapter and charging method therewith. The adapter comprises: a power supply input module, a power supply output module, a battery capacity detection module, a temperature detection module and a control module. The adapter performs detection on a nominal battery capacity of a terminal, determines a maximum permitted charging current according to the battery capacity of the current terminal, and outputs a charging electrical signal in compliance with the maximum permitted charging current. The charging method performs detection on a battery capacity of a terminal currently connected for charging, and adapts for a maximum permitted charging current for charging the terminal, thus meeting the charging demands of terminals having different charging current requirements, and improving universality of a charger for terminals. In addition, a battery temperature of a currently connected terminal is detected to terminate charging in a timely manner when the battery temperature is too high, thus protecting the battery. Moreover, real-time detection of a charging current of a battery enables an output current of the adapter to be within a range of a maximum permitted charging current throughout the entire charging process, thus ensuring the integrity of battery charging.

Description

technical field [0001] The invention relates to terminal charging technology, in particular to an adapter and a charging method thereof. Background technique [0002] The current terminal charging implementation is divided into two parts from the physical function, namely the charger and the charged terminal. Among them, the charger is responsible for converting the high-voltage electric energy of alternating current (AC) into low-voltage energy of direct current, which is generally 5V voltage, so as to provide it to the terminal; and the terminal itself is designed with a charging chip, which is responsible for charging the battery of the terminal Carry out specific charging management, including the management of the external input current, the battery charging current, the charging voltage, and the realization of battery temperature protection, etc. [0003] The existing terminal charging technology has the following problems: [0004] On the one hand, it is manifested ...
