電池過(guò)流保護(hù)片基本知識(shí)介紹
|
過(guò)流保護(hù)片概述：過(guò)流保護(hù)片是專門(mén)用于防止由于濫充電而引起的電池過(guò)溫，電池過(guò)溫是電池組設(shè)計(jì)人員主要關(guān)心的問(wèn)題。鋰電池組中盡管有過(guò)壓及過(guò)流檢測(cè)安全保護(hù)電路，（包括集成電路及為在有過(guò)強(qiáng)的靜電放電、溫度過(guò)高以及短路的情況下半導(dǎo)體電路會(huì)出現(xiàn)故障。）但在電壓保護(hù)電路失效而又沒(méi)有溫度保護(hù)的情況下，電池就會(huì)在過(guò)充或?yàn)E充時(shí)產(chǎn)生過(guò)多熱量，使電池破裂、漏液、冒煙、甚至燃燒。 |
