Description

Method and device for displaying power of dual batteries

This application claims priority from Chinese patent application CN201810866103.4 entitled "Method, Device and Computer-readable Storage Medium for Displaying Electric Power by Dual Battery", filed on August 01, 2018, the entire contents of which are incorporated herein by reference. .

Technical field

Background technique

With the increase of mobile terminal applications such as mobile phones, the power consumption generated by them gradually increases, so the capacity of the battery is required to increase. Under the existing battery technology, a larger battery capacity means a larger and thicker battery. If it becomes larger, it limits the size and location layout of the mobile terminal circuit board and components, which affects the design of mobile terminals such as mobile phones; if it becomes thicker, it increases the overall thickness of the mobile phone and affects the appearance of the mobile phone.

Based on the contradiction in the current single-battery solution in the design of mobile phones, combined with the advent of dual-screen models, the design of dual-battery solutions has become increasingly possible. Dual batteries can be implemented in series or in parallel. The use of two batteries in parallel mode is more complicated. The two batteries can be powered alternately or both batteries can be powered simultaneously.

In order to ensure the accuracy of the display, the power of both batteries can be displayed, but this method has a poor user experience. To ensure the user experience, you can choose one of them. A battery level is displayed on the LCD, but the battery level indication is not accurate. It can be seen that the user experience and the accuracy of the display cannot be balanced.

Different fuel gauges work on the principle Also different, the common ways are:

1.Battery open circuit voltage detection method

Taking the current commonly used lithium-ion battery as an example, there is a definite relationship between the battery terminal voltage and the remaining capacity. The remaining capacity can be estimated by measuring the battery terminal voltage. Therefore, the earliest method of power detection was obtained by monitoring the battery open circuit voltage The remaining capacity.

2.Coulomb detection method

This power detection method needs to monitor the amount of charge flowing in and out, and calculate the remaining power through a certain algorithm, so it is called the coulomb measurement method. This method has a higher accuracy in the calculation of the amount of electricity. The learning algorithm of the charging-discharging process can show the actual capacity change of the battery.
