Lithium-sulfur battery pack with automatic alarming function

Abstract

The invention discloses a lithium-sulfur battery pack with an automatic alarming function. The lithium-sulfur battery pack comprises a lithium-sulfur battery pack body and an automatic monitoring and alarming system, wherein the automatic monitoring and alarming system is arranged on an integrated plate inside the lithium-sulfur battery pack body; an embedded CPU (Central Processing Unit), a timer and an ampere meter are sequentially connected to the middle part of an inner cavity of the lithium-sulfur battery pack body from right to left; in addition, a buzzer is connected to one side of a lithium-sulfur battery pack casing; a red indicating lamp and a green indicating lamp are sequentially connected to the other side of the lithium-sulfur battery pack casing from left to right; the automatic monitoring and alarming system comprises the embedded CPU arranged on a circuit board inside the lithium-sulfur battery pack body. According to the lithium-sulfur battery pack disclosed by the invention, residual electric quantity of the lithium-sulfur battery pack is detected and calculated by using a specific calculation formula and arranging corresponding detection elements; in addition, after comparison processing, whether the lithium-sulfur battery pack needs to be charged or not is judged, so that the problem that a user blindly charges is avoided, the charging times are reduced, the charging time is shortened, and the generation of an intermediate is reduced.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium-sulfur battery pack with an automatic alarm function. Background technique [0002] Lithium-sulfur battery is a kind of lithium battery, which is still in the research stage as of 2013. Lithium-sulfur batteries use sulfur as the positive electrode of the battery and metallic lithium as the negative electrode. The specific capacity is as high as 1675mAh / g, which is much higher than the capacity of lithium cobalt oxide batteries widely used in commerce. In addition, sulfur is an environmentally friendly element that basically has no pollution to the environment, and is a very promising lithium battery. Lithium-sulfur batteries use sulfur as the positive electrode reactant and lithium as the negative electrode. During discharge, the negative electrode reaction is that lithium loses electrons and becomes lithium ions, and the positive electrode reaction is that...
