Problems solved by technology

However, it is difficult to reduce the total power impedance
In addition, if the battery has been used for a long time, the battery impedance will increase, making the total power impedance correspondingly higher and making the above problem worse

Abstract

An electronic system (300) comprising: a battery (303); at least one electronic device; and a power managing unit (301), arranged for detecting a battery voltage of the battery (303), and arranged for limiting at least one performance of the at least one electronic device if the battery voltage is not higher than a first low threshold voltage.

Description

[0001] cross reference [0002] This application claims priority to US Provisional Patent Application Serial No. 61 / 981,294, filed April 18, 2014. The aforementioned US Provisional Patent Application is hereby incorporated by reference. technical field [0003] The invention relates to a power management method and an electronic system applying the power management method. In particular, the present invention relates to a power management method for avoiding a sudden drop in battery voltage and an electronic system applying the power management method. Background technique [0004] Traditionally, portable electronic systems (eg, mobile phones, laptops, or tablets) contain batteries for power. However, if the battery's cell voltage suddenly drops due to a load spike, many problems can arise. [0005] figure 1 is a schematic diagram describing the voltage drop problem of a conventional battery. Such as figure 1 As shown, due to the appearance of the peak load P, the b...
