Problems solved by technology

[0003] However, in practical applications, there will also be a problem with the fuel gauge of the smart terminal, that is, the fuel gauge display is very different from the actual battery power during charging and discharging.
This seriously affects the experience brought by the smart terminal to the user.
[0004] Existing fuel gauge performance testing technology often manually conducts some free tests related to fuel gauges manually. Due to limited manual energy, the fuel gauge tests performed are often not very comprehensive, and the test depth is not very deep. Just do the most basic check of the fuel gauge, it is difficult to solve the performance test problem of the fuel gauge in an all-round way

Abstract

The invention discloses a coulometer test method and device. The method comprises that coulometer test is started when a terminal starts charging or discharging, and an initial electric quantity value of charging or discharging of the terminal serves as a first initial electric quantity value or a second initial electric quantity value; in the charging or discharging process of the terminal, at least one electric quantity value and at least one battery voltage value of the terminal are obtained at set time interval; and when the terminal completes charging or discharging, a coulometer test result is obtained according to whether the electric quantity value or the battery voltage value satisfies set standard. The coulometer test method is automatic and comprehensive, human participation is not needed in the test process, the test result is automatically generated, the test efficiency is greatly improved and the test result is accurate.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, in particular to a method and device for testing an electric quantity meter. Background technique [0002] Now the functions of smart terminal software are becoming more and more powerful, software updates are more frequent, and smart terminals are used more and more frequently, making battery life a bottleneck in the development of smart terminals at present. But battery life is certainly an important indicator, but how to make the battery power display more accurate is also very important, especially how to inform the user of the battery power in real time and accurately when the battery is low is very necessary, in addition to avoiding In addition to problems such as automatic shutdown caused by inaccurate display, it can also help users better plan battery usage, so as not to affect normal use. It is based on this that fuel gauges came into being. Fuel gauges have been ...
