Abstract

The embodiment of the invention provides a charging device and a mobile terminal, and belongs to the technical field of charging of batteries. The charging device comprises a charging interface, a charging circuit, a battery pack, a first switching module and a control module, wherein the battery pack comprises at least two charging batteries; the charging circuit is connected between the charging interface and the battery pack in series; the first switching module is electrically connected with the battery pack; and the control module is connected with the first switching module and controls the first switching module to switch the connection state between the charging batteries into a parallel state or a series state. The problem of heating of the batteries caused by over-high circulating currents of the batteries is solved, so that, by the charging device provided by the embodiment, the problem of heating of the batteries caused by current rise of battery bodies can be effectively solved when the batteries are quickly charged.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of battery charging, and in particular, to a charging device and a mobile terminal. Background technique [0002] With the development of communication technology, mobile terminals (such as mobile phones, personal digital assistants and tablet computers, etc.) have more and more functions and their functions are gradually integrated. For example, mobile phones have functions such as cameras, navigation and games in addition to traditional calling functions. As the mobile terminal has more and more functions, there are more and more power consumption units, and the charging problem of the mobile terminal has also become a hot spot that people pay attention to. [0003] The existing mobile terminal adopts a single battery design, and in order to speed up the charging speed, it is necessary to increase the charging current of the mobile terminal. In the process of realizing the present i...
