Battery power value calibration method and device thereof

Abstract

The embodiment of the invention discloses a battery power value calibration method and a device thereof. The method comprises the following steps that a preexisting resistance value corresponding to a battery is acquired, battery state information and the current display power value of the battery are detected, and the battery state information includes completion of charging or discharging of the battery; the battery state information is matched with the current display power value; when the battery state information is not consistently matched with the current display power value, a current resistance value is calculated; and the preexisting resistance value is updated by the current resistance value so as to calibrate the power value of the battery. With application of the battery power value calibration method and the device thereof, the more accurate resistance value can be obtained so that accuracy of detection of the battery power value can be enhanced.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and a device for calibrating a battery power value. Background technique [0002] With the continuous development of electronic technology and network technology, terminals such as mobile phones, tablets, and notebooks have become indispensable necessities in people's lives. Most terminals use nickel-cadmium batteries, nickel-metal hydride batteries, or lithium-ion batteries for power supply, and display the power value on the terminal screen to indicate the battery usage status, so that users can flexibly manage the available power. [0003] Most of the existing terminals use a fuel gauge to calculate the power value. Specifically, the current flowing through the resistor is calculated by collecting the voltage drop of the resistor, and the current integration can be used to calculate the power value charged into the battery or the power value discharged f...

Problems solved by technology

However, in the process of calculating the power value, the resistors use uniform hardware configuration parameters. Due to the differences in the raw materials, patch and assembly processes of resistors from different manufacturers and different hardware batches, there is a large error in the resistor value. If you use Unified hardware configuration parameters calculate the power value, resulting in the situation that the battery is not fully charged but the battery is fully charged, and the power value shows that it can continue to be used but suddenly powers off and shuts down, which brings a lot of inconvenience to users and reduces the accuracy of battery power value detection. sex
