The battery charging device and method

The present invention belongs to the technical field charging, there is provided an apparatus and method for battery charging. The present invention, in the process of charging the battery, the power adapter to charge the battery in accordance with the normal charging mode by using a power adapter comprising a charge control module and a battery charging apparatus, when the output current value of the power adapter for a preset time interval while in conventional current interval, the power adapter and the charging control module fast charge inquiry communication, sent battery voltage information to adjust the output voltage fast charge instruction command, the power adapter feedback charge control module to the power adapter charging control module, and in that when the output voltage matches the fast-charge voltage condition preset charge control module, the power adapter according to adjust fast charge mode output current and output voltage to charge the battery, and the charge control module simultaneously introduced direct current from the power adapter to charge the battery, enabling the battery fast charge to reduce the charge time of the object.
