Problems solved by technology

In fact, although the battery power is divided into 5 parts, the power represented by each part is not equal, and the charging current during the charging process is not a constant value, so the user's estimated charging time is uncertain.

Abstract

The embodiment of the invention discloses a determination method, a determination device and terminal equipment for charging time. The determination method for the charging time comprises the following steps: a current charging current value, a currently applied electricity consumption current value and a current battery voltage are detected, and the current electric quantity of a battery is obtained according to the current battery voltage; and the remaining time needed by finishing the charging of the battery is determined according to the current charging current value, the currently applied electricity consumption current value, the current electric quantity of the battery, total electric quantity of the battery, and the ratio between the charging electric quantities at different stages of the charging of the battery and the total electric quantity of the battery, thereby realizing the determination of the remaining time needed by finishing the charging of the battery and prompting the remaining time.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and terminal equipment for determining charging time. Background technique [0002] Due to the requirements of portability and mobility, terminal devices such as mobile phones are usually powered by batteries. After the battery power is consumed within a certain period of time, the user needs to charge the battery to meet the power supply demand. [0003] The existing technology obtains the current battery voltage through voltage sampling in a uniform cycle, and at the same time, according to the mapping relationship between the battery voltage and battery power in the charging curve, and the battery power and the number of charging grids, the LED (Light Emitting Diode, light-emitting diode) is obtained through mapping calculation. ) or LCD (Liquid Crystal Display, liquid crystal display) displays the number of charging grids. [0004] The prior ...
