過流保護片概述:過流保護片是專門用于防止由于濫充電而引起的電池過溫,電池過溫是電池組設計人員主要關心的問題。鋰電池組中盡管有過壓及過流檢測安全保護電路,(包括集成電路及為在有過強的靜電放電、溫度過高以及短路的情況下半導體電路會出現故障。)但在電壓保護電路失效而又沒有溫度保護的情況下,電池就會在過充或濫充時產生過多熱量,使電池破裂、漏液、冒煙、甚至燃燒。
華巨公司推出一種新型條狀過流保護片,與以往產品相比電阻低,該器件能同時起到過流保護及過溫保護的作用,專為降低電池組阻抗、滿足更長工作時間要求的便攜式電子產品而設計。特別適合于鋰離子及鎳氫等對溫度較為敏感的二次(可充電)電池。
電池過流保護片和電池組里面的原電池串聯在一起,無論溫升是由短路造成的還是由過充引起的,器件都可以發揮保護作用,無須熱熔斷絲或雙金屬斷路器。此條狀器件采用鎳做引腳,尺寸又小又薄,可直接焊到原電池上,既節省空間,又降低安裝費用
