Abstract

The invention belongs to the technical field of charging and provides a cell charging device and method. In the process of charging a cell by utilizing the cell charging device comprising a power adapter and a charging control module, the power adapter charges the cell in a conventional charging mode first; when the output current value of the power adapter is in a conventional current range in a preset time interval, the power adapter is in quick charge inquiry communication with the charging control module; after the charging control module sends a quick charge instruction command to the power adapter, the power adapter adjusts output voltage according to the cell voltage information fed back by the charging control module; when the output voltage accords with the preset quick charge voltage condition of the charging control module, the power adapter adjusts output current and output voltage according to the quick charge mode so as to charge the cell; and meanwhile, the charging control module introduces a direct current from the power adapter to charge the cell, and thus the purpose of reducing charging time by carrying out quick charge on the cell is realized.

Description

technical field [0001] The invention belongs to the technical field of charging, and in particular relates to a battery charging device and method. Background technique [0002] At present, the battery of electronic equipment is charged through its power adapter, and the power adapter usually uses a constant voltage output method to charge the battery, but for a large-capacity battery, charging the battery through a constant voltage output method will cause charging time It is too long, so the above-mentioned prior art cannot realize fast charging to the battery to shorten the charging time. Contents of the invention [0003] The object of the present invention is to provide a battery charging device, aiming to solve the problem that the prior art cannot realize fast charging of the battery to shorten the charging time. [0004] The present invention is achieved in this way, a battery charging device, which includes a power adapter and a charging control module, the power...
