Problems solved by technology

[0007] To sum up, we have no way of knowing how long each battery can supply the voltage required to make the load operate normally, so we need a reliable way to indicate whether the primary lithium battery is short of power

Abstract

A method and device for indicating the power shortage state of spare battery is provided, which comprises: starting up the spare battery; monitoring the spare battery; when the power shortage state is monitored, it will indicate the power shortage state. The device comprises a startup module for starting spare battery, a monitor module for monitoring spare battery, a power shortage indicating module for indicating the power shortage state after monitoring module's monitoring. The invention thus realizes the credible indication for power shortage state of spare battery.

Description

technical field [0001] The present invention relates to a method and device for indicating the state of power shortage of a spare battery, and more particularly, to a method for indicating whether a primary lithium battery is short of power. Background technique [0002] Primary lithium batteries are a widely used power supply for portable electronic devices. [0003] Sometimes the disposable lithium battery is used as the backup power of the system. During the use process, the battery power is the key to the use of the battery, and it is also the key to whether the data can be saved when the system is powered off. General disposable lithium batteries have a limited usage time under the condition of specific current consumption. [0004] Under a specific load, the usage of the battery is shown in the graph of Figure 1. [0005] It shows that under a specific load, the time for the battery to supply voltage above 2.0V is about 1200 hours. And in the case of different load ...
