Abstract

The embodiment of the invention provides a charging device and a charging method thereof. The charging device comprises a charging chip, a controller, a pulse controller and a first switch device, the charging chip is connected with a power supply, the first switch device and the controller, the controller detects the battery information to obtain the type of the battery, outputs the current control information corresponding to the type of the battery to the charging chip according to the type of the battery, and outputs the pulse control information corresponding to the type of the battery to the pulse controller according to the type of the battery; the charging chip outputs current to the battery through the first switch device according to the current control information; and the pulse controller controls the switch frequency of the first switch device according to the pulse control information to allow the charging chip to perform pulse charge through the first switch device and employs larger charging current when the battery is subjected to constant current charging so as to improve the battery charging speed.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a charging device and a charging method thereof. Background technique [0002] At present, there are many ways to quickly charge mobile phones, including high-voltage charging and low-voltage high-current charging. Mobile phone battery charging is usually divided into three steps. The first step is trickle charging, that is, when the battery voltage is relatively low, usually below 3.4V , in order to protect the battery from being damaged, the charging IC will charge the battery with a small current, about a few hundred mA; the second step is constant current charging, that is, when the battery voltage reaches 3.4V or more, the charging IC will charge the battery with a large current, The charging current in this step is much larger than the charging current in step 1; step 3 and 4 constant voltage charging, that is, when the battery voltage reaches the nominal ma...
