Battery power display device and method

Abstract

The invention discloses a battery power display device and method. The method includes: collecting battery voltage values ​​in real time; obtaining the average value of the current battery voltage according to the battery voltage values ​​collected multiple times within a predetermined period; judging the current battery voltage value; The change range of the average voltage value relative to the previous average battery voltage value. When the change range is greater than a predetermined threshold, the current battery voltage average value is converted into a battery power value; and the battery power value is displayed. The current battery voltage value is determined by averaging the battery voltage values ​​saved by multiple samples, so that one or two large changes in the battery voltage value will not affect the large change in the battery voltage average value, and the change in the battery voltage average value Only when the change range of the average battery voltage is greater than the predetermined threshold, the battery power is updated and displayed, which can ensure the accuracy of the battery power display, and at the same time make the battery power display smooth without jumping.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a battery power display device and method. Background technique [0002] Batteries are used in mobile phones and mobile devices, and people often pay attention to the power of the battery. Therefore, the display of battery power is very important for users to understand the power status of the current device, and it also directly affects the user experience. [0003] In the long-term research and development work, the inventor found that the battery power in mobile devices such as mobile phones is displayed inaccurately. If the battery power display is inaccurate or unstable, it will affect the user experience of the product, such as: battery power display In the process of use, it suddenly jumps: it will display 50% for a while, then 40% for a while, and then 50% for a while. Especially in smart phones, the power display is more likely to jump, because when using some ap...

Problems solved by technology

Although this kind of processing overcomes the development of jumping, it introduces another problem, that is, the accuracy of the battery power display is poor, and the power display is not smooth enough, and the user can only see a few fixed power values ​​forever.

Another solution is to add a battery power detection chip (IC), and use the IC to obtain the real-time power of the battery, but this solution increases the cost due to the increase of the hardware IC.
