Problems solved by technology

However, when using the current voltage measurement method to measure battery power, the working state of the mobile communication terminal is generally not considered, that is, the measured voltage does not consider the load and current of the battery brought by the working state of the mobile communication terminal. The influence of the measured voltage, which greatly affects the accuracy of the battery power measurement in the voltage direct measurement method
[0013] For example, during the service period of a mobile communication terminal, because the battery discharge current varies with time in different service states, it is difficult to determine a fixed time to measure the battery voltage, and it is also difficult to use a fixed compensation value for the measured voltage value. to compensate

Embodiment Construction

[0037] A mobile communication terminal is generally in two states, namely a standby state and a service state. In the standby state, the power consumption of the mobile communication terminal is generally small. In the service state, the battery current of the mobile communication terminal has different characteristics according to the service type of the mobile communication terminal. For example, a TD-SCDMA mobile communication terminal is in TDMA (Time Division Multiple Access) mode, which transmits and receives data in units of subframes when conducting communication services, and allows multiple uplink transmission slots and reception slots in each subframe, Transmitting time slots and receiving time slots are interleaved with each other, and generally speaking, the battery current of a mobile communication terminal is relatively large when transmitting time slots. Therefore, when a communication terminal in the TDMA mode performs services, the current magnitude generall...

Abstract

A method for measuring electric capacity of battery on mobile communication terminal includes selecting different chance to measure voltage of battery when mobile communication terminal is on standby state or on communication state then confirming electric capacity of battery on mobile communication terminal according to condition of measuring out voltage of battery on mobile communication terminal.

Description

technical field [0001] The invention relates to a method for measuring battery power of a TD-SCDMA mobile communication terminal. Background technique [0002] For the convenience of users, the new generation of mobile communication terminals integrates more and more functions. In addition to traditional communication functions, some data processing functions, such as surfing the Internet, processing emails, taking pictures, and video recordings, are also integrated on mobile communication terminals. . The increase of functions will inevitably lead to the increase of system power consumption, so battery management has become a crucial link in the design of mobile communication terminal products. [0003] For mobile communication terminals, it is very important to accurately measure the remaining battery power. During the working process, the mobile communication terminal continuously tracks the remaining power of the battery, and controls the charging and discharging proce...
