Abstract

Embodiments of the present invention relate to the technical field of intelligent terminals, and disclose a terminal device, a charging method and a power calculation method. The terminal device provided by the present invention comprises: a charging interface and N charging circuits, wherein N is a natural number greater than 1. N charging circuits are connected in parallel to the charging interface; and the charging circuit comprises a charging battery and a charging chip, the charging battery is electrically connected with the charging chip, and the charging chip is electrically connected with the charging interface. The charging chip charges the charging battery according to a preset charging current, and the preset charging current is less than a preset threshold. According to the embodiments of the present invention, while achieving fast charging, the heat generated by the battery is minimized to the greatest extent and the battery life can be prolonged.

Description

Technical field [0001] The embodiments of the present invention relate to the technical field of smart terminals, and in particular to a terminal device, a charging method, and a power calculation method. Background technique [0002] With the advent of the intelligent era, the continuous improvement of software and hardware has greatly increased the power consumption of mobile phones, and fast charging technology has also emerged. Fast charging technology refers to adjusting the input voltage and current value of the mobile phone through the chipset, thereby increasing the charging power of the battery and shortening the charging time. There are three common adjustment methods: increasing voltage constant current, increasing current constant voltage, and simultaneously increasing voltage and current. [0003] The inventor found that there is at least the following problem in the prior art: in the process of fast charging with high current, the battery generates a lot of heat. Su...
