Problems solved by technology

However, when charging with a large current, due to factors such as the charging circuit, battery protection board, and battery internal resistance, the battery voltage will be too high, and it will enter the constant voltage charging stage too early, which not only affects the charging efficiency, but also reduces the user's charging time. sense of experience

Abstract

The invention discloses a charging control device and method. The device comprises a detection module and a charging control module, wherein the detection module is used for, when a terminal is charged, detecting the voltage of a terminal battery according to a preset detection cycle; and the charging control module is used for, when the voltage of the terminal battery is smaller than or equal to a preset voltage threshold, charging the terminal battery via a constant current charging mode. By adopting the device and the method, the real voltage of the battery can be accurately detected at the constant current charging phase, so that the influence of over high battery voltage is avoided, the constant current charging time is prolonged, and the charging efficiency and the user experience are improved.

Description

technical field [0001] The present invention relates to the technical field of terminal charging, in particular to a charging control device and method. Background technique [0002] In the current terminal charging technology, with the gradual development of the technology of reducing charging heat, a larger charging current can be used for fast charging in the process of terminal low-voltage fast charging (ie, constant current charging). However, when charging with a large current, due to factors such as the charging circuit, battery protection board, and battery internal resistance, the battery voltage will be too high, and it will enter the constant voltage charging stage too early, which not only affects the charging efficiency, but also reduces the user's charging time. sense of experience. Contents of the invention [0003] The main purpose of the present invention is to propose a charging control device and method, which can accurately detect the real voltage of t...
