Abstract
The battery of mine-used portable equipment selecting suitable protection mode after the treatment of intrinsically safe can meet the safety requirements of battery components.In this paper,using a typical lithium battery as an example,in an explosive environment of single lithium battery overcharge,short circuit,two battery parallel connection test and external explosion case,whether the battery itself is explosion or can cause environmental explosion around the explosion is found.Real time monitoring test of pressure and temperature changes in the two cases of the opening and closing of the pressure relief valve in the explosion protection box is provided.Studies show that the lithium battery itself has a huge explosion pressure and temperature rise is high with a certain risk.关键词
