Charging apparatus, power supply method, terminal device and charging method

Abstract

The embodiment of the invention discloses a charging apparatus. An output matching circuit of the charging apparatus includes the following components of: a first communication module which establishes a communication connection with a communication module of a terminal device, and receives a parameter configuration request message which is sent by the terminal device and includes a rated parameter value of the terminal device, and sends the parameter configuration request message to a processing module; the processing module which sets an output value matched with the terminal device according to the rated parameter value; and a switching power source which is used for adjusting the output of the charging apparatus so as to make the output equal to the output value matched with the terminal device. The embodiment of the invention also provides a power supply method, a terminal device and a charging method. With the charging apparatus, power supply method, terminal device and charging method of the embodiment of the invention, matched working voltage and current can be provided for different brands and categories of terminal devices, and the universalization of the charging apparatus can be realized, and environmental protection can be benefitted.

Description

Technical field [0001] The present invention relates to the technical field of terminal power supply, in particular to a charging device and a power supply method, a terminal device and a charging method. Background technique [0002] Terminal devices generally use rechargeable batteries to provide power. Rechargeable batteries need to be replenished regularly, and the power required for charging is generally converted from 220V alternating current by the charger. [0003] Such as figure 1 Shown is the working principle diagram of a prior art charger. In the prior art, the charger 1a converts 220V alternating current into 5V direct current voltage, and outputs it to the terminal device 3a through the USB connection line 2a to charge the rechargeable battery of the terminal device 3a. [0004] With the continuous updating of terminal equipment types and the increasing popularity of terminal equipment, the generalization trend of chargers has received more and more attention. For ex...

Problems solved by technology

However, due to the different voltage standards of different brands or types of terminal equipment, there are certain differences in the voltage or current required for the operation of each terminal equipment, so that the compatibility between the respective chargers corresponding to each terminal equipment still has a certain degree of difficulty. Difficulty

[0006] Therefore, in the prior art, it is difficult to achieve compatibility between chargers corresponding to different brands or types of terminal equipment
